   Abstract:	Loss of teeth not only leads to aesthetic but also to functional impairment of the stomatognathic system. Solving edentulousness still presents a great challenge in contemporary dentistry. Various approaches are possible depending on the type and number of lost teeth, and also the condition of surrounding tissue. Regardless of whether it is a case of a single tooth or several, it is necessary to know the function of the masticatory organ and therapeutic procedures in order to correctly carry out treatment. Lack of teeth can be dealt with orthodontically, prosthetically or implanto prosthetically. Which method is chosen depends on the case itself, choice of therapist and on the practicability and cooperation of the patient. This study presents several cases which were treated by classical prosthetic restorations, as opposed to several similar cases which treated by intra-osseous implants and prosthetic constructions on the implants.The purpose of this presentation is to show different methods of treatment of the same or similar cases, and to give guidelines to clinicians, when and in which cases a particular treatment should be opted for. It is important to mention that the information acquired by the therapist, as well as the patient, represents the key role in the choice of the most suitable therapeutic procedure.

   MeSH:	LYMPHOMA, NON-HODGKIN
   Abstract:	Non-Hodgkin lymphomas (NHL) are a heterogenetic group of lymphoproliferative neoplasms, characterised by the occurrence of malignantly changed lymphocytes in a lymph node, and rarely primary in other organs. The disease most frequently manifests with painlessly enlarged lymph nodes, which in the gastrointestinal and urinary tract may cause compression. Infiltration of the bone marrow causes insufficiency of myelopoiesis, resulting in anaemia, trombocytopenia and neutropenia. Classification of the disease is based on PHD and peripheral blood findings.Extranodular disease occurs most frequently in the gastrointestinal tract, and also often occurs in the sinuses, thyroid gland, salivary glands, breasts, kidneys and lungs. Approximately 25% of extranodular lymphomas first occur on the head and neck in the so called Waldeyer's ring, although primary lymphomas of the oral cavity are rare.We present the case of a 63-year-old man with primary occurrence of NHL on the gingiva. The suspect lesion in the oral cavity was noticed during extraction of an inflamed root in the upper jaw. The lesion was located in the immediate vicinity of odontogenic inflammation, although it was not connected with it, and thus a specimen was taken for biopsy. The radiographic finding did not show anything specific. PHD finding of the lesion showed necrosis, bleeding and polymorphonuclear inflamed infiltrate and a tumorous mass with atypical lymphocyte cells. After a further examination by a haematopathologist NHL was confirmed with a high degree of B-cell malignancy. Immunohistochemistry confirmed giant cell NHL, B immunophenotype, and the patient's condition was defined as NHL II E.

   MeSH:	ORAL HYGIENE DENTAL CARIES
   Abstract:	The aim of this study was to assess the influence of certain oral hygienic habits (such as general hygiene of the mouth, frequency of toothbrushing, toothbrush hardness) on non-carious lesion development. The study was conducted on 873 subjects, aged 10 yrs or older. Results showed that there is a statistically significant difference regarding oral hygiene between subjects with cervical lesions and those without them. Furthermore, there is no statistically significant difference in non-carious cervical lesion development regarding frequency of toothbrushing and toothbrush hardness.

   MeSH:	BRUXISM
   Abstract:	The aetiology of temporomandibular disorders (TMD) remains controversial. The role of bruxism is still under discussion.The objective of this investigation was to determine the effect of bruxism on the function of the stomatognatic system.A group of 46 bruxers, aged from 24-52 years (x = 35.03 ± 6.92) was examined. The control group consisted of 50 nonbruxers aged from 25-51 years (x = 37.24 ± 6.37) bruxism was assessed by a questionaire and clinical examination. A precise calliper was used to measure jaw movement. Maximal opening, right and left aterotrusion, and maximal protrusion were measured. The mean value of maximal opening in the bruxers group was 48.51 ± 5.01 mm, and in the nonbruxers group 49.76 ± 6.92 mm. Ther mean value of maximal right laterotrusion in the bruxers group was 10.04 ± 2.51 mm, and of left laterotrusion 9.74 ± 2.50 mm compared to thenonbruxers group where the mean value of right laterotrusion was 10.31 ± 2.47 mm, and left laterotrusion 10.33 ± 2.30 mm. The mean value of maximal protrusion in the bruxers group was 9.53 ± 1.97 mm, while in the nonbruxers group it was 10.81 ± 2.29 mm. Pearson ?2 test analysis shows statisticaly significant difference (p < 0.05) between the groups only in relation to the maximal protrusion(t = 2.93, p = 0.0004).The results of this study suggest that bruxism may only have a limited influence on mandibular mobility.

   MeSH:	TEMPOROMANDIBULAR JOINT DISORDERS + diagnosis DENTAL OCCLUSION
   Abstract:	The influence of occlusion on the occurrence of sound in the temporomandibular joint had not been complately proved.The objective of this investigation was to determine the effect of type of occlusion on the occurrence of sounds in the TMJ.A group of 96 subjects, aged from 24-52 years (x = 35.03 ± 6.92) was examined. The type of occlusion was dentermined by clinical examination. Depending on the contacts on the laterotrusal and mediotrusal side the subjects were categorized into three groups (canine guided occlusion, group function and balanced occlusion). The existence of sounds was registred by means of a clinical examination and auscultation by stethoscope.In the examined group 70.83% of examinees had canine guidance, 16.66 % group function and 12.5 % balanced occlusion. Temporomandibular joint sound was present in 41.6 % of subjects. The results of the statistical analysis (Pearson ?2) shows no statistically significant difference between these 3 groups (?2 = 2.09 p = 0.351).The results of this study suggest that the type of occlusion does not have an influence on the occurrence of sound in the TMJ.

   Type of Article:	congress abstract
   MeSH:	BONE REGENERATION DENTAL IMPLANTATION + methods
   Abstract:	Loss of anterior teeth can be caused by pathological processes, tooth retention (mostly upper canine), result of trauma (avulsion or root fracture) or missing tooth germ.Such defects can be solved by orthodontic treatment (orthodontic space closure), prosthetic treatment (different bridge constructions) or with surgery treatment (dental implants). Inadequancy of orthodontic therapy is long lasting rehabilitation ond mostly esthetical imperfection. At the bridge constructions, hard tissues of adjacent teeth must be removed. Another contraindication is the presence of diastemas. Dental implants enable making selfsupporting mastication units, but require sufficient bone to adequately stabilise. When there are changes in alveolar bone height and width, we use guided bone regeneration (GBR). GBR has proved to be a suitable technique for promoting bone regeneration. GBR treatment with collagen membranes may significantly enhance bone regeneration.The left first incisor of a 27 years old patient was extracted because of resorptive processes on alveolar bone as a result of longitudinal fracture of the root. Immediately after extraction, the bone defect was filled with Bio-Oss spongiosa granules and covered with Bio-Gide resorbable bilayer mambrane. After one year the defect was restored to nearly original condition and ITI Straumann implant was placed. Because of labial dehiscence Fisiograft was used. The definitive restoration was placed after 6 months.

   Title in English:	An Evaluation of the Quality of Tooth Preparation with Intraoral Parallometer-Axisgraph - Pilot Study
   Title in Croatian:	nema
   Type of Article:	congress abstract
   MeSH:	TOOTH PREPARATION
   Abstract:	Measuring of the axial angle in practice shows an average angle of 20 degrees. The result of the high taper angles is a nonsatisfactory resistance form in 22.5% cases. The purpose was to examine the efficiency of the Jonjić oral parallelometer, known as the "AXISGRAPH", with respect to basic ergonomic rules, leading to savings in working energy and time and an increase in the qualityof the preparation.METHODS: On the basis of clinical cases models were made of the upper and of the lower jaw of acrylic resin. The practitioner, who has 10 years experience, initially prepared each model set in a KAWO-EWL model, conventionally using freehand preparation, and then withan Axisgraph. Both models were in the same condition. Comparison was made between the time required for preparation, working energy used, and the quality of the preparation. The quality of the preparation was determined using the axial angle of the prepared tooth, measured by the method described in Jonjic's dissertation.RESULTS: The freehand preparation took 80 minutes while preparation with the Axisgraph took 50 minutes. The average angle in freehand preparation was 15.03 degrees while, (the average angle of preparation was 10.4 degrees) using Axisgraph, and in 30 minutes less time than the freehand preparation.CONCLUSION: Preparation with the Axisgraph significantly saves time on preparation and allows better quality for the prepared tooth.

   MeSH:	SUBMANDIBULAR GLAND + radiation effects
   Abstract:	INTRODUCTION: Life-long severe xerostomia is a common complication after radiotherapy of head and neck malignancy. It is a clinical entity which causes a great deal of suffering and disability for the patient. Saliva is an important factor for denture retention. Hyposalivation causes reduced retention of full dentures. The aim of the study was to determine late consequences of irradiation in the mouse submandibular gland.MATERIAL AND METHODS : Mouse submandibular glands were locally X-irradiated by single dose irradiation with 15Gy. Day 90 post-irradiation tissues were analyzed by morphology and morphometry.RESULTS: Strong vacuolization of almost all acini was noted. Kariopyknotic nuclei were found in numerous acini and the largest amount of acini was in the lysis. The epithelial cells of the granular convoluted tubule were degenerated and desquamated in the lumen, and some granular convoluted tubules were in the lysis. In the interstitial connective tissue disseminated focal mononuclearinfiltrate was found. With respect to the control group a statistically significant decrease in the number of acinar cells (p<0.001) was determined, as well as a significant increase in the number of granular convoluted tubule cells (p<0.001). Whereas the number of intercalated duct cells was not different with respect to the control (p=0.10).CONCLUSION: The results of this study suggest that hypofunction in the late stage is a consequence of morphological changes and loss of acinar cells. The patients should use a saliva substitute to alleviate their symptoms easier.

   MeSH:	DENTAL OCCLUSION DENTAL CARIES + epidemiology ROOT CARIES
   Abstract:	INTRODUCTION: The term 'noncarious cervical lesions’ (NCCL) stands to indicate the loss of hard tissue at the tooth cervix. This loss can be caused by different physical and/or chemical agents. One of the causes of NCCL can be occlusal stress, which lead to toothflexureand loss of enamel at the cervical area. In different types of occlusion there are numerous lateral eccentric movements that can cause NCCL. The purpose of this study was to determine differencesin the frequency of NCCLs between patients with different occlusal conception.METHODS AND RESULTS: The study involved 815 persons over the age of 10 years, chosen at random. The cervical third of the vestibular surface of the upper and lower teeth was clinically examined. NCCLs were measured with plus and minus. The type of occlusal conception was established by clinical examination and classified as canine guidance, group function and combinedocclusion. The results showed that the NCCLs were equally participatein both sexes, and in all three types of occlusion (Chi-square values were 1.96, df=2, p>0.05).CONCLUSION: The results of the study indicate that there is no statistically significant difference in the frequency of NCCLs between patients with different occlusal.

    MeSH:	DENTAL OCCLUSION
    Abstract:	OBJECTIVE OF INVESTIGATION: The aim of the study was to determine anterior tooth relationship (overbite and overjet) according to the type of occlusion (canine guided, group function).METHODS: A total of 111 test subjects (56 men and 55 women, mean 23.9 years of age) were examined, and it was determined that they have occlusional conception. The relationship of the front teeth in the position of maximum intercuspidation was evaluated by a portable meter.RESULTS: By analysing the obtained results of vertical overjet and horizontal overbite of the front teeth, we concluded that there was significant statistic difference in the amount of the vertical overjet with regard to occlusional conception (t=6.669, p=0.00001). Average value of the vertical overjet in examinees with occlusion leadby the canine was 2.22+0.09 mm, while in examinees with group function it was 1.58+0.26 mm. No significant statistical difference was found by analysing vertical overjet with regard to gender. No significant statistical difference between the groups was found by comparing the results of horizontal overbite of frontal teeth with regard to occlusional concepcion and gender. Average value of horizontal overjet was 1.62+0.29 mm.CONCLUSION: Subjects with canine guided occlusion have significantly and statistically bigger overjet of frontal teeth.
