   Title in English:	Tooth wear related signs in the croatian navy employees
   Title in Croatian:	Znakovi povezani s trošenjem zuba kod pripadnika Hrvatske ratne mornarice
   Type of Article:	original scientific paper
   MeSH:	(no MeSH data)
   Abstract:	Objective: The objective of this study was to determine the severity of tooth wear in a sample of Croatian navy employees and to evaluate oral signs and demographic factors related to it. Materials and Methods: The sample included 1092 navy employees aged 20 to 60 years (mean age 37.06±7.85), 985 men and 107 women. The tooth wear severity measurements were based on the relative degree of faceting (0-4 scale). The tooth wear score (the sum of all facets scores) and tooth wear index (average annual growth of sum of ratings corrected for the percent of missing teeth) were correlated to demographic data, masticatory muscles hypertrophy, masticatory muscles tension upon awakening, tooth mobility, linea alba, tongue indentations, traumatic ulcers, noncarious cervical lesions (NCCL), number of teeth and self-reported bruxism in order to determine the specific correlates of tooth wear. Results: The percentage of teeth with occlusal wear ranged from 21.66% in the youngest age group to 52.45% in the oldest age group. The tooth wear score was highest in 40-60-year-old subjects, and lowest in 20-30-year-old subjects. The stepwise multiple linear regression analysis showed that increased tooth wear was significantly associated with NCCL (ß=0.55, p<0.001), tongue indentations (ß=0.17, p<0.001), male gender (ß=- 105, p<0.001), muscle tension (ß=0.103, p<0.05), and muscle hypertrophy (ß=0.063, p<0.05). The R² of the model was 0.49. Conclusion: The results of this study suggest that NCCL, tongue indentations, muscle tension, male gender and muscle hypertrophy are potential factors that may influence or predict tooth wear. There was no significant relationship or association between tooth wear index and linea alba, tooth mobility, traumatic ulcers and self report of bruxism.

   MeSH:	TEMPOROMANDIBULAR JOINT DISORDERS JAW RELATION RECORD OCCLUSAL SPLINT
   Abstract:	Temporomandibular disorder is the term that includes all functional disturbances of temporomandibular joint and masticatory muscles. This paper deals with one of the most common types of temporomandibular disorders that is articular disc displacement into an anterior position or so called articular disc dislocation. The most common risk factor related to this disorder is trauma. This can be a macrotrauma, such as an impact into the jaw, or microtrauma, which is related to chronic muscle hyperactivity or the occlusal instability. Magnetic resonance imaging is used for noninvasive evaluation of temporomandibular joints and soft tissues. Although irreversible therapeutic means are recommended for temporomandibular disorder treatment, the most common dental treatment is reversible and noninvasive which implies occlusal stabilization splint fabrication. This paper reports a case of a female patient with anterior articular disc displacement of her left temporomandibular joint and the treatment by a stabilization splint in order to obtain functional effi ciency of her masticatory system.

   Abstract:	Oral lichen planus (OLP) is a chronic inflammatory disease which is characterized by an immunoreactivity directed against basal keratinocytes and mediated by T/lymphocytes. However, it is well known that salivary immunoglobulins have important role in the protection of mucosal surfaces. The aim of this study was to determine salivary immunoglobulin A1 (IgA1) and IgA2, together with IgG 1,2,3,4 subclass levels in patients with oral reticular lichen planus during acute stage and remission period as well as in comparison to the controls. In the whole resting saliva of 19 patients with OLP, age range 30-72, mean 58 years in acute phase and during remission period, and in 21 controls, age range 20-52, mean 35 years, salivary IgA and IgG subclasses were determined with radial immunodiffusion and enzyme immunoassay respectively. There were no significant differences in salivary IgG1 and IgG2 as well as IgA1 and IgA2 between patients in acute phase and controls (p>0.05). Patients in acute phase had significantly increased IgG3, IgG4 and proteins in comparison to the controls (p=0,021; p=0,004; p=0,029). No significant differences could be found between patients in acute phase and during remission period in IgG1,2,3,4 and IgA1 while IgA2 was significantly increased in acute phase in comparison to the remission period (p=0,049). Between patients in remission period and controls there were no significant differences in any IgA or IgG salivary subclasses (p>0,05). We can conclude that acute phase is characterized with increase in IgA2 which might reflect increased activity of secretory immunity as a possible result of microbial stimulation seen in acute phase in comparison to the remission period.

   Type of Article:	original scientific paper
   MeSH:	COMPOSITE RESINS DENTISTRY, OPERATIVE
   Abstract:	Degree of conversion of composite materials is an important factor that influences both quality and longevity of the composite restoration during polymerization. Besides the components of the composite material, degree of conversion is greatly influenced by properties of the light source and polymerization time. The purpose of this study was to compare the effect of three polymerization modes of various intensities (medium, exponential and standard) of Elipar Trilight halogen curing (3M/ESPE, Seefeld, Germany) unit on samples of Tetric Ceram (Vivadent, Schaan, Liechtenstein) and Filtek Z 250 (3M/ESPE, Seefeld, Germany) on the surface and at 2 mm depth. For determining the degree of conversion, Fourier transform infrared spectroscopy (FTIR) was used. Results of the degree of conversion measurement showed the highest degree of conversion when using light source of highest intensity as well as a higher degree of conversion on the surface than at 2 mm depth regardless of the type of composite material and light intensity used for polymerization.

   Type of Article:	congress abstract
   MeSH:	CARCINOMA, SQUAMOUS CELL
   Abstract:	Nonaromatic naphthalane (NAVS) is a specific fraction of Croatian oil, extremely rich in steranes from which the aromatic system is removed. Steranes are attributed with bioactivity similar to steroid hormones, modulators of tumour growth. Encouraged by the results of earlier in vitro and in vivo studies on the inhibitory effect of NAVS on the growth of planocellular carcinoma, we carried out a study on its effect on oral planocellular carcinoma (OPCC) in mice.Aims: 1) To test the validity of the simple experimental model OPCC, 2) to test possible antiproliferative effect of NAVS on the above model by monitoring tumour growth, 3) to test the antineoangiogenic effect of NAVS to explain the possible antiproliferative effect, and to estimate the possibility of crisis reactivity of anti-human immunohistochemical markers with mice tissue. A suspension of 100 μl s 105 SCC VII cell was inoculated intraorally under the buccal mucous membrane in 48 syngeneic C3H mice. Seven days after inoculation the animals were divided in six equal groups and the mice, depending on the group, were intratumorously injected with 100 μl of the following substances: paraffin oil (PO) as a negative control, NAVS (in one group 7 days, and in the second group 14 days, after inoculation of the tumour), 1.25 dihydroxyergotamine (1.25-D3) as a positive control, and a combination of NAVS with 1.25 D3 and PO with 1.25- D3. Tumour growth was monitored weekly by measuring with callipers. The animals were sacrificed 1, 2, 3 and 4 week after application of the tested substance. Histological specimens of explanted tumours were stained with hematoxylin-eozine, and immunohistochemically with anti-CD34 antibodies for estimation of tumour neoangiogenesis. Compared with the PO group, tumour growth and angiogenesis were decreased in the 1.25-D3 and NAVS groups. NAVS probably reduced growth by OPCC inhibition of vascular proliferation, needed for tumour growth.

   Title in Croatian:	Suvremena dijagnostika i terapija temporomandibularnih disfunkcija (TMD)
   Type of Article:	congress abstract
   MeSH:	TEMPOROMANDIBULAR JOINT DISORDERS
   Abstract:	Temporomandibular dysfunction in al its variety tends to present a problem with high morbidity and increasing prevalence in the dental office. A systematic approach to gathering and interpreting clinical evidence must be the primary goal when dealing with patients who suffer from TMD signs and symptoms.According to W. Bell diagnosis of TMD must:• Properly identify and classify the disorder.• Establish the mechanism of dysfunction and the source of pain.• Determine the etiology, if possible.• Provide a basis prognosis in the light of effective therapy.As a result of these principles we can canclude that TMD is not an acceptable diagnosis. It refers to a group of diseases with overlapping and similar signs and symptomatologies and cannot be solely used to determine appropriate therapy.Apart from good clinical judgement the patient can benefit from any inanimate objective measuring device which improves the clinician’s sensory acuity. Information obtained from electomyography, electrosonography, electrokinetic and axiographic tracings analyzed properly can aid in assessing what a specific TM disorder does toa patient and the effect treatment has on that disorder.

   MeSH:	TEMPOROMANDIBULAR JOINT DISORDERS + therapy INLAYS
   Abstract:	In some cases of heavily damaged posterior teeth, especially those on which endodontic treatment was performed, there is no possibility for full prosthodontic treatment. An alternative is chair side made composite inlay, onlay and overlay.These fillings can be made in the special partial articulator (Easy Croc, Girrbach Dental Gmbh, Germany) which makes them sutiable for final treatment of temporomandibular dysfunctions. Impressions are taken by a special a bimaxillary tray which is then poured into stone type IV gypsum and at the same time mounted in an articulator. Standard composite resin is modelled according to similar occlusal morphology of neighbouring teeth and gnathological rules. Occlusion is then adjusted in the articulator and programmed to a chosen occlusal scheme. Complete work is finally polymerized outside the mouth which eliminates shrinking stress and increases polymerization ratio. After try in, such work finally cemented using composite dual luting cements and then polished. Such chair side made prosthodontic devices increases the structural integrity of heavily damaged posterior teeth and can provide adequate treatment for the TMD patient.

   Title in English:	Pilocarpine-Hydrocloride Has a Short-Time Effect on Reducing Xerostomia
   Title in Croatian:	Pilokarpin-hidroklorid ima kratkotrajan učinak u liječenju kserostomije
   Type of Article:	congress abstract
   MeSH:	XEROSTOMIA + therapy PILOCARPINE + therapeutic use
   Abstract:	Xerostomia, i.e. oral dryness, is mainly caused by side effects of medications, immunologic diseases, e.g. Sy. Sjoegren, and radiation treatment for oral and neck cancer. There are variable, although far from satisfactory, treatment options, including that of muscarinic receptor agonist pilocarpine-hydrochloride. Pilocarpine treatment of salivary hypofunction is not yet an established method in croatia.The aim of this preliminary study was to assess the autcome of oral administration of pilocarpin on minor salivary glands and whole saliva production, as well as to monitor possible side effects and patients subjective responses to treatment.Is was a single blind-placebo controlled trial. Ten patients suffering from xerostomia underwent this trial. Patients with cardiac or pulmonary diseases were excludet, as well as those that did not show any increase in salivary flow rate after administration of ascorbic acid solution (chemical stimulant) at inclusion testing one week prior to the experiment. The experiment comprised 7 repeated measurements in time intervals of 15-30 min., from the baseline up to 2 h after single oral administration of 5 mg of pilocarpine hydrochloride ( 5 drops of slution, Pilokarpin 2%, pliva, Croatia). The flow rate of minor salivary glands was measured on the lower lip and palate by means of Periotron (Oraflow Inc., Plainview, USA) and whole saliva was collected in calibrated test tubes . A simple questionnaire was filled in to record patients subjective perception of treatment. The same procedure was repeated one week later, when dexpanthenol drops (DPanthenol, Ljekarne Zagreb, Croatia) were used as placebo instead of pilocarpine.Pilocarpine increased salivary output and gave symptomatic relief in every patient. The differences in salivary output were significant both compared to baseline and to placebo controls (p = 0,01). There were no side effects during the trial, either after administration of pilocarpine; or placebo. After increasing salivary flow rate the action of pilocarpine decrease in time, which was recordable during the observation session.Respecting possible contraindications and side effects, according to our finding pilocarpine should be regulary used in treatment of xerostomia.

   Title in English:	Periotron as a Modern Sialometric Method in Xerostomia Diagnosis and Treatment Monitoring
   Title in Croatian:	Periotron: Suvremena sijalografijska metoda u dijagnostici i u nadzoru liječenja kserosromije
   Type of Article:	congress abstract
   MeSH:	XEROSTOMIA + diagnosis
   Abstract:	The Periotron micro-moisture meter (Oraflow, Plainview, USA) is an electronic instrument that has been designed for gingival vrevicular fluid (GCF), periodontal pocket fluid (PPF), salivary flow and saliva thickness measurments, by using a variety of paper collection strips. Collection strips (Periopaper strips, PerioCol strips, Sialopaper strips) are applied to the oral tissues of interest for a certain period of time, after which the are inserted between Periotron electrodes. The special insulation coating on the electrodes enables them to work as two plates of a capacitor, being able to measure submicroliter quantities of oral fluids. Periotron displays the numerical output on LCD. By inputting data obtained during prior calibration process into Periotron professional software for Windows, we design a standard curve, from which we interpolate actual fluid volume. We have designed a single blind placebo controlled study to evaluate possible presence of long-term effect of pilocarpine-hydrocloride (PHC) on salivary flow rate in patients with xerostomia. 12 patients suffering from xerostomia underwent this trial. We used strict inclusion criteria regarding the possible side effects. Six patients were instructed to self-administer 5 mh of PHC (5 drops of solution, Pilokarpin 2%, pliva Zagreb, Croatia), three times a day, for 7 days. Another 6 patients (placebo group) were instructed to take 5 dexapanthenol drops (D panthenol, Ljekarne Zagreb, Zagreb, croatia), 3 times a day for 7 weeks. The flow rate of minor salivary glands was measured on the lower lip and palate by means of Periotron and whole saliva was collected in calibrated test tubes. mesurements were repeated once a week. Each patient filled in an extensive Oral Health Impact Profile questionnaire (OHIP) at te baseline and after completion of PHC treatment to monitor oral health influence on patients lives. After 7 weeks of treatment the placebo group was swiched to PHC, but there no apparent need for switching pilocarpine group to placebo, because we found no improvement in salivary flow rate after 7 weeks of treatment. in the group previously taking placebo, there was also no improvement in salivary flow rate after taking PHC. OHIP findings were calculated and showed no statistically significnt improvement after 7 weeks of PHC administration. One patient from the pilocarpine group and one from palcebo group ( while taking placebo) reported side effects and discontinuited the trial. oral administration of PHC does not seem to produce log-term salivary flow rate increase, but rther immediate and shortr lasting improvement. Judging by Periotron and whole saliva scores, our results showed that PHC is not able to “cure” xerostomia after prolonged administration, i.e. there is no residual effect in salivary gland simulation once the drug is discontinued and eliminated.

    Abstract:	The term temporomandibular dysfunction (TMD) encompasses a group of disorders of the masticatory muscles and temporomandibular joints. Major precipitating factors are occlusal, traumatic, psychosocial and systemic factors. The aim of this investigation was to determine possible altered muscular function in patients with TMD, as well as to determine the need for EMG application in TMD diagnosis. Forty young adults participated in this study: 13 subjects with signs and symptoms of TMD and 27 asymptomatic subjects, sex and age matched. Surface EMG recordings were obtained from left and right anterior temporal muscle, left and right masseter muscle and from left and right digastric muscle in eight mandibular positions. Right side to left side ratio of examined muscles myoelectrical signals in lateral occlusal and maximal lateral positions for the asymptomatic group showed significantly higher activity of the working side anterior temporal muscle (p<0.05). In the group of patients with TMD, regarding the same muscle, statistically significant differences were found only in the left occlusal and left maximal lateral position (p<0.05), at which greater activity was found for the working side temporal muscle. In the same positions of the right side no significant differences in anterior temporal muscle activity were found (p>0.05). Comparison of myoelectrical signals in the position of maximal intercuspation of teeth between the patients and the controls, showed significantly higher activity in right and left masseter muscle at 50% MVC (p<0.05) in the symptomatic group.Results of this investigation showed the presence of altered masticatory muscle activity in TMD patients and confirmed the use of electromyography in TMD diagnosis.

    MeSH:	MASTICATORY MUSCLES + physiology DENTAL OCCLUSION
    Abstract:	The aim of this study was: 1. To measure latency and duration of the silent period elicited in an open-close-clench cycle in individuals with all teeth and normal occlusion. 2. To compare the latency and duration of a silent period between the different elevator muscles examined and the symmetry of the reflex responses. 3. To analyze isotonic and isometric muscle activity in open-close-clench cycles and to compare it to the maximum voluntary myoelectric activity. Silent periods were registered and measured in 62 individuals with normal occlusion on the EMGA-1 apparatus. Ten registrations of an open-close-clench cycle was made for each participant to elicit silent periods. Signals from the right and left anterior temporal and left and right masseter muscles were recorded by surface electromyography during 240-300 ms. Silent periods had a latency of 12.5-12.9 ms after the occlusal contact and had only a single short inhibitory pause with complete inhibition of motoneurons. The duration of the silent period was 20.1-21.1 ms. There were no statistically significant differences (p>0.05) of the silent period latency and duration between the examined muscles and the left and the right side. Isotonic muscle activity was equal to isometric muscle activity for each muscle in open-close-clench cycles. The mean isotonic muscle activity was spontaneously constant between open-close-clench cycles and was approximately 60% to 70% of the mean muscle activity during maximum voluntary clencing. The reflex was considered oligosynaptic. The reflex was fully symmetrical and of equal latency and duration between the examined muscles. Stimulation of the primary mechanoreceptor afferents in periodontal ligament by tensile forces generated between occlusal tables of opposing teeth and/or vibration of the unique teeth contact (normal occlusion) and consequent stimulation of mechanoreceptors in temporomandibular joint, tendons or muscles by vibration could be responsible for the reflex.

    Type of Article:	congress abstract
    MeSH:	DENTAL CASTING TECHNIQUE
    Abstract:	Type IV gypsum (stone gypsum) is an essential material in prosthetic treatment. Improper handling can change hardness, expansion and compressive strength and it is the most common reason for inaccurate casts. In that case even the most perfect impressions will result in inadequate prosthetic treatment. Using optical instruments-digital camera (2.5 million pixels) and digital microscope we attempted to identify the visual appearance of inadequate casts and relate them to specific causes. All casts were poured in highly controlled conditions and only one factor, whose influence we tried to determine, was changed during the procedure. Most common mistakes are: outdated gypsum, incorrect powder to water ratio, mixing without a vacuummixer, pourring without a vibrator and etching by alginate acid. All the mistakes were visualised, easily recognized and categorized by using digital optical equipment.

    Abstract:	The aim of this prospective study was to record the presence of Candida albicans yeast in a geriatric population, and to compare the results between denture wearers and non-wearers, in order to evaluate the role of dentures as a factor influencing Candida growth. We performed an oral examination on 217 institutionalized elderly people living in the hospice "Sv. Josip" in Zagreb, recorded dataregarding oral health and collected detailed information on denture wearing status. Furthermore, we performed oral smears for Candidacultures, cultivated on Sabouraud's dextrose agar (“Emmon's”) at 37°C for 48 hrs and counted the Candida colonies. Collected data were stored in the database created for this purpose in "Microsoft Access 2000". The number of Candida colonies from denture wearers andnon-wearers were compared (Man-Whitney U test, p<0.05), and the obtained results are discussed.

    Abstract:	The aim of this study was to measure main variables influencing mandibular function-movements of mandible during chewing, speech and breathing. Measurements taken were: vertical and horizontal overlap of central incisives, side shift from centric relation (CR) to maximal intercuspation (MI) measured in the sagittal and frontalplain, maximal mouth opening, maximal mouth opening using force, maximal dextrotrusion and sinistrotrusion. Method used included the same number of subjects and examiners. This was achieved by educating final year dental students before the measurement took place. They were both examiners and subjects for each other. Comparison of this method to single examiner and multipleexperienced examiner methods revealed no statistically different results. Measurements were divided by gender, dental status, and the number of signs and symptoms related to temporomandibular dysfunctions (TMD) that were then statistically analyzed. There were no significant differences between the results of this study and findings in current literature.

    MeSH:	ELECTROMYOGRAPHY MASTICATORY MUSCLES + physiology MASTICATION
    Abstract:	Mastication is a highly coordinated neuromuscular function that involves fast effective movements of the jaw and continuous modulation of muscle force. To understand the relationship between muscles during mastication it is necessary to know the position and direction of movement of the mandible.MATERIAL AND METHODS: Twenty-four young healthy adults, age ranged 17 to 27, participated in this study. They were chosen among dental students of School of Dental Medicine University in Zagreb and had to be free of sign and symptoms of TMD. Surface EMG recordings were obtained from left and right anterior temporal muscle, left and right masseter muscle and from left and right digastric muscle on the 8 channel PC based EMGA-1, apparatus for simultaneous recording of myoelectrical activity (6 differential EMGchannels, input impedance 100 MW, CMRR> 95 dB at 50 Hz, bandwidth 2 Hz-1 kHz, programmable input sensitivity from 100mVpp to 20 mVpp, an 8 bit resolution A/D conversion, 2 kHz sampling rate) - occlusal sound (2 audio channels), specially designed and developed for the purpose of kinesyological examinations of stomatognathic system’s function. The disc electrodes (Ag/AgCl,diameter 10 mm) were placed 2 cm apart in the main direction of the muscle fibres.RESULTS:1. Main effect of factor "functional movement" was significant at p<0.01, and values were the highest for gum chewing, and the lowest for empty chewing except fordigastric musclewhich had lowest values at continuous isometric contraction.2. Main effect of factor “muscles” was significant at p<0.01 for all muscles involved, values were similar for the same muscles on left and right side.3. Main effect of factor “time” was statistically significant p<0.05 for all cases showing decreasing trends except in last minute duringfunctional movements.4. Interactions between factors “functional movement” and “time” were present at significance p<0.01.

    Abstract:	Improving retention and stability of complete dentures is of considerable interest in prosthetic dentistry. Approaches to this problem over the years have included overdentures, implants and denture adhesives. Although denture adhesives are widely used, there are few quantitative data on the effects of an adhesive on denture retention and stability during normal functional activities. The purpose of this investigation was to study the influence of denture adhesive on the surface EMG activity of the masticatory muscles in a sample of complete denture wearers. In this study 6 denture wearers were investigated. Surface EMG recordings were obtained from left and right anterior temporal and masseter muscle and from the sub-mandibular group in the region of the anterior belly of the digastric muscle on the left and right side. Data were recorded during standardized jaw positions that included clenching in the position of maximal intercuspation of teeth (at 100%, 50% and 25% of the maximum activity), lateral eccentric positions, maximal lateraleccentric positions, protrusion, maximal protrusion and wide opening. The results demonstrated higher digastric muscle activity in protrusion with the teeth at an edge-toedge position after the use of adhesive (p<0.05). In the laterotrusive position, after the use of adhesive, the working side elevator muscles activities increased, although without any statistical significance (p>0.05). This investigation demonstrated that patients were able to produce greaterlevels of muscle activity in protrusive and laterotrusive positions with the use of adhesive.

    MeSH:	DENTURE + adverse effects ALVEOLAR BONE LOSS + etiology DENTAL ABUTMENTS
    Abstract:	Loss of interdental alveolar bony septum can be determined directly from a radiograph as a percentage length of the interdental bony crest of the alveolus to the distance from cemento-enamel junction of the tooth to the tooth apex. The aim of this study was to measure the height of interdental alveolar bone around the abutment and nonabutment teeth in removable partial denture wearers (RPD) on dental panoramic radiographs (DPR) through a period of six months. Twenty RPD patients (5 males, 15 females participated in the study. The alveolarbone loss measurement was performed on DPRs, using Shei index, on each mandibular abutment and non-abutment tooth on its mesial and distal side, after the RPD delivery and six months later. Recordings of plaque index (PlI) were made at the mid-buccal, mid-palatal, mesio- and disto-palatal surfaces of each abutment and non-abutment teeth after the RPD delivery and six months later. Theresults revealed a decrease of Shei index values on both abutment and non-abutment teeth, which reached a statistically significant level for distal Shei index values of the abutment teeth and mesial and distal Shei index values of the non-abutment teeth (p<0.05) in a 6 month period. There was no statistically significant difference inPlI values between the first and the second measurement (p>0.05). We concluded that the decrease in bone support on both abutment and non-abutment teeth was attributed to the high levels of PlI and low level of oral hygiene than to RPD loading.

    MeSH:	PROSTHODONTICS + trends INTERNET EDUCATION, DENTAL
    Abstract:	Since the late sixties when the ARPANET- first computer network was developed, Internet has had a great impact on the way of thinking, buying, teaching, learning and everyday life, including dentistry. The beginning of internet in science and research, has proved to be irreplaceable way of communication between researchers all over the word. Currently (April 2002) one of the most popular search engines on the net (Google) indexed about 2 billion web pages, 35 million of non HTML documents and 700 million Usenet messages, which makes the Internet the greatest information service ever. The purpose of this study was to investigate which part of the web space is taken by prosthetic dentistry and the importance which it gains on the Internet. The method used was standard Internet search engine keyword queries preformed using six web search engines: Google, Lycos, Infoseek, AltaVista, Northern Light, HotBotand Excite. Research results suggest that there is currently (May 2002) about 30 thousand pages (0.0015% of searched web space) which contain terms: prosthetic dentistry or prosthodontics and about one thousand web pictures connected to these terms. Content analysis suggests that quality and real informative value of the majority of those pages is low. To conclude-informative space on the Internet concerningprosthetic dentistry is still in development and the need for confirmation and authorized information is obvious.

    MeSH:	DENTURE, PARTIAL PATIENT SATISFACTION SOCIOECONOMIC FACTORS
    Abstract:	The aim of this study was to evaluate patients' satisfaction with their partial dentures in relation to some socio-economic variables. The aim was also to evaluate patients' satisfaction with denture retention, speech, aesthetics, chewing ability and comfort while wearing dentures. The influence of some factors, such as age, sex, marital status, level of education, smoking, chronic diseases, socio-economic status, ordinal number and age of thepresent dentures, on patients' satisfaction with partial dentures was also evaluated. A total of 165 patients with partial dentures took part in the study. There were 59 males and 106 females aged between 38 and 87 years. Patients graded their satisfaction with their partial dentures in total and then graded aesthetics, speech and retention, chewing ability and comfort while wearing dentures by using a scale from 1 to 5. Following a statistical analysis the following conclusions were made: 1. Patients were mostly satisfied with their partial dentures (the distribution of the scores of the patients' assessments was asymmetrical towards the highest scores in all examined categories). Only 3.2% of the patients were not absolutely satisfied with their partial dentures, 2. More then half of the examined patients scored all the examined variables in the best score category (5), 3. Patients of a higher level of education had higher criteria for the aesthetic appearance, as they assessed their partial denture aesthetics with a lower grades than patients with lower level of education. Males were less satisfied with the chewing ability of lower partial dentures (p<0.05) than females, 4. There was no significant difference in patients' assessments of the quality of their partial dentures between different age groups, ability of self-supporting life, socio-economic and economic status, marital status, smoking, presence of chronic diseases, number of previous dentures and age of present dentures (p>0.05).
