   Abstract:	The purpose of the study was to evaluate cytotoxicity of AH Plus, compared to AH26 in vitro on Chinese hamsters V79 fibroblasts. The materials were prepared according to the manufacturer's instructions. After the initial setting period, the materials were crumbled and dissolved in dimetil-sulfoxide solution. The extracts obtained were incubated at 37C during one hour, 24 hours and 7 days. After incubation period the samples were diluted with Eagle’s minimum essential medium to concentrations ranging from 1.67 μg/ml to 167 μg/ml. Each concentration was placed on a plate with 24 wells with 5x103 V79 cells per 1.2 ml of medium. The number of cells was counted by electronic counter and the percentage of viable cells was determined by a light microscope. Both materials, AH26 and AH Plus were found to be cytotoxic. In both materials cytotoxic effect was related to the concentration of endodontic sealer in the extract solution. The critical concentrations, above which the sealers totally destroy the cell line are between 5.57 μg/ml and 167 μg/ml for AH Plus and 16.57 μg/ml and 167 μg/ml for AH26. The setting time did not have a statistically significant effect an cytotoxicity.

   MeSH:	MARGINAL ADAPTATION (DENTISTRY) INLAYS DENTAL PORCELAIN MATERIALS TESTING DENTAL CAVITY PREPARATION COMPOSITE RESINS
   Abstract:	The aim of this study was to analyse the quality of marginal adaptation of ceramic inlays, fabricated by the Cerec 2 CAD/CAM method after cementation with two different materials (Tetric and Compolute). The study was carried out on 20 extracted premolars and molars on which ceramic inlays were fabricated. The first 10 inlays were cemented with a composite material with microparticles (Tetric), and the other 10 with a dual composite cement (Compolute). The samples were cut in the vestibular-oral direction and in the mesialdistal direction and analysed with a stereomicroscope, OPTON SV 8, with 160x magnification. Adaptation of the inlay after cementation with Tetric was ideal in 82%, good in 16% and bad in 2% of the samples. In the vestibular-oral direction (occlusally) complete adaptation was determined in 34%, negative adaptation in 20% (the inlay was not completely seated on the cavity wall) and positive in 46% of the samples (the inlay was higher than the surface of the prepared cavity). In the mesiodistal direction (gingivo-approximal) complete adaptation was determined in 54.8% of the samples, negative in 19% and positive in 26.2%. After cementation with Compolute ideal adaptation was determined in 70%, good in 25% and bad in 5% of the samples. Complete adaptation was recorded in 35.9%, negative in 38.5% and positive in 25.6% of the samples. Difference in the quality of adaptation of inlays in the vestibular-oral and mesiodistal direction was not statistically significant. Cerec inlays were completely adapted in more than 50% of the samples. Mean value of variations in the vestibularoral direction (occlusally) amounted to negative 555.29 m and positive 332.19 m, which is statistically significantly less. Mean value of variations in the mesiodistal direction (gingivo-approximal) amounted to negative 710.31 m and positive 361.39 m, which is statistically significantly less. The obtained results indicate that both materials are suitable for clinical use.

   MeSH:	ALVEOLAR BONE LOSS + therapy BONE MATRIX BONE SUBSTITUTES BONE REGENERATION APICOECTOMY PERIODONTITIS + surgery TRANSPLANTATION, HETEROLOGOUS
   Abstract:	Large bone defects of the jaw have, so far, been filled with various types of bone implants, mainly synthetic nonresporative aloplastic implants (hydroxilapatite). As we have data only for two types of resorptive xenogenic bone implants, the purpose of this investigation was to examine resorption and osteoinductive capability of OSTEOVIT as a material for filling bone defects after removing large cysts (more than 20 mm in diameter) and after apicectomy of the tooth, where more than 1/3 of the tooth has no strong bone bases.Osteovit is a collagen matrix of calf spongiose consisting of porous collagen purified of antigens, fats minerals, enzymes and all other noncollagen materials.Forty-one patients, 9 female and 32 male aged 15-54 years were included in the investigation Nineteen of them had a clinical diagnosis of OPC and 22 a clinical diagnosis of cysts radicularis. All patients had a indication for apicectomy indicating that they had bone defects larger than 20 mm in diameter or destructive alveolus along more than 1/3 of the tooth root.The results are shown on the basis of a clinical follow up and radiographic examination 6 months, 1,2,3 and 4 years after surgery. If, in some cases, a fistula was found during the postoperative followup the treatment was recorded as clinically unsuccessful. Success on the basis of radiographic criteria was also evaluated. First we classified defects into periapical (circumscriptive) and those along the tooth root and than divided the rays into two groups.Unfortunately results for only for 22 patients were abtained and the others were excluded from the investigation because of incomplete follow-up.With regard to total success, according to clinical criterium, 20/22 patients had good clinical diagnosis, i.e. 91%. By radiographic analysis we found complete healing in 13/22 patients or 59%. We also analysed results according to the localization of the periapical change. It was concluded that patients with circumscriptive changes were 88% clinically successful while those with a defect along the tooth root were 93% clinically successful.According to the results of this investigation it can be concluded that OSTEOVIT is a very good resorptive material for filling bone defects and with OSTEOVIT it is possible to widen indication for apicotomy to include cases where more than 1/3 of the tooth has no strong bone base.

   Title in English:	Suggested parameters in the assessment of stomatopyrosis
   Title in Croatian:	Prijedlog parametara u procjeni stomatopiroze
   Type of Article:	original scientific paper
   MeSH:	BURNING MOUTH SYNDROME + diagnosis
   Abstract:	Stomatopyrosis is a state characterized by a burning sensation in the oral cavity. Various etiological factors contribute to the occurrence of stomatopyrosis. They may be local, systemic and psychogenic. As it was not feasible to gain any accurate and detailed diagnostic and therapeutic effect, and due to the differences in the definition of stomatopyrosis as a disease, we designed a questionnaire which can helpto solve the problem. Our research was conducted on 60 subjects, 30 suffering from stomatopyrosis and 30 in a control group, with no clinical pathological oral finding. Members of both groups were persons of the same age. With regard to sex, both groups included a female population. The testing was conducted by means of a questionnaire, which, apart from general data on the subjects, included subjective and objective assessments of the symptoms present in the oral cavity. General data required referred to the subjects age, sex and occupation. Objective assessment comprised localization of symptoms, their description, intensity of symptoms, their frequency, the time of their occurrence, factors intensifying symptoms, change in taste, etc. Subjective assessment was conducted by means of thermoestesiometric measurement and visual analogue scale (VAS-scale). The findings showed that stomatopyrosis occurs in older subjects, primarily female. The localization of symptoms was confined mostly to lips. Description of the symptoms showed that the burning sensation was the most frequent symptom occurring within the oral cavity. The intensity of the symptoms in the mouth cavity was reported to be unbearable and as far as the frequency of the symptoms is concerned, it was said to be of a continuous nature. The symptoms occur in the daytime, and factors contributing to intensification of the symptoms are anxiety and dentures. The subjects taste was also reported to be changed. Visual analogue scale showed a high subjective assessment of the intensity of the symptoms, while thermoestesiometry did not reveal any inflammatory changes in the oral cavity.These findings suggest that our questionnaire can contribute to better diagnostic and therapeutic effects and help to establish an accurate definition of stomatopyrosis and its occurrence.

   Abstract:	Staphylococcus aureus and Enterococcus faecalis species were used for the experiment. 0,5 McFarland bacterial inoculum was diluted using saline in proportions 1:10, 1:10 2, 1:10 3, 1:10 4, 1:10 5 and 1:10 6. 0.2 millilitre of solving agent was mixed with an equal quantity of bacterial suspension. Sixty specimens, 10 for each proportion, were prepared. Specimens were hermetically closed and left for 10 and 30 minutes. 0.1 millilitre of each specimen was planted to the blood agar and put in the thermostat at 37°C for 24 hours. The procedure was repeated twice. Halothane exhibited greatest antibacterial activity, destroying all concentrations of Staphylococcus aureus and Enterococcus faecalis. Eucalyptol showed activity towards Staphylococcus aureus, while orange oil did not show any antibacterial effect on the examined bacteria.

   MeSH:	BONE MORPHOGENETIC PROTEINS BONE REGENERATION ALVEOLAR BONE LOSS + therapy PERIODONTIUM REGENERATION PERIODONTAL DISEASES + therapy
   Abstract:	Bone morphogenetic proteins are a group of nine known proteins which represent factors of growth and differentiation with the ability of inducing new bone. Osteoinduction is a precisely defined sequence of biological reactions which lead to the transformation of mesenchymal cells into cartilage and bone.In vitro and in vivo, studies have demonstrated that in order for proteins to realise their clinical function they need carriers. So far ACS (absorbable collagen sponge) has been most frequently used as a carrier. However the search for the best carrier continues. Investigations carried out so far on experimental models (rats, dogs, minipigs and chimpanzees), and in human volunteers, have indicated the great potential of BMP in the reconstruction of bone defects of the stomatognathic area. Promising results have been obtained so far in periodontal surgery, augmentation of alveolar ridges, augmentation of the floor of the maxillary sinus, treatment of periimplantitis and treatment of larger bone defects after extirpation of tumours.

   Abstract:	Although cleft palate patients are not regularly seen in general dental practice, their number is not negligible. Prosthodontic treatment of such patients requires good planning, taking into account the remaining teeth and roots, deformation of maxillary segments, residual palatal defect and the disproportion between the upper and lower alveolar ridge.The authors describe prosthetic therapy of a cleft palate patient using root copings, modified Dolder bar, cone and veneer crowns with rests and metal base partial prosthesis, with the aim of providing satisfactory function, aesthetics and alleviation of the deformities.

   Abstract:	A 22 year-old man was referred to our Department for evaluation of white hyperkeratotic multiple flakes, together with tiny erosions localized on both cheeks. Detailed medical history and clinical examination revealed habitual cheek biting as a result of a bad habit, which was manifest with a typical clinical finding. During treatment we applied a combination of salycil acid and corticosteroids as well as vitamin A drops and the patient was advised to stop the bad habit, and to take sedatives during states of nervousness. The therapy resulted in complete regression of the lesions.
