The most common oral solitary pigmented lesion is the dental amalgam tattoo. It occurs as a result of colouring of the tissue by alien pigment which was administered intra or subepidermaly either intentionally or accidentally. The most common material used for the colouring of the oral mucosa is amalgam from amalgam fillings and metal particles from prosthetic restorations which are absorbed accidentally. The oral mucosa tattoos are most often found in the area of the marginal gingiva or the buccal mucosa. The metal particles may accidentally reach the area of the oral mucosa during various dentistry interventions. The therapy most often involves surgical intervention with excisional biopsy while in the recent period the low power laser therapy has provided exceptional results. The aim of the paper was to present the successful removal of the oral mucosa tattoo in a single visit.

Objective. Th e aim of this paper is to determine the concentration ofnitric oxide (NO) in the saliva of subjects resulting from the presenceof various metal restorative activities in the oral cavity. Patients andmethods. Th e research was conducted on 20 subjects (12 women and8 men), aged 18-30, with no metal fi llings in their oral cavity and 20subjects (11 women and 9 men) aged 18-30 with prosthetic and conservativework in their oral cavities made of various metals. Th e pHof the saliva was established by means of an “Orion” type pH meter atan optimal temperature of 250C. Th e concentration of NO was determinedby conversion of NO3-2 into NO2-2 with the help of elementaryzinc and then by colorimetric testing of the NO2-2 concentration bymeans of the Griess reagent. Results. Our results established that theconcentration of NO in patients with various metals (60.18±10.24) is33.7% higher, which is statistically insignifi cant, in relation to the controlgroup (45.01±6.28). Conclusion. Various metal restorative activitiesstemming from dentistry practice do not cause changes in the pHvalues of saliva and NO concentrations.

Oral environment of orthodontic patients undergoes changes, such as pH reduction, largernumber of sites available for Streptococcus mutans collection, and increased accumulation of foodparticles, which may lead to an increased number of S. mutans colony-forming units (CFU) insaliva. Chlorhexidine gluconate (CHX) is the most potent documented antimicrobial agent againstMutans streptococci and dental caries. The aim of this work was to assess efficiency of CHX-basedmouthwashes in patient with fixed orthodontic appliances. Methods: Twenty patients with fixedappliances were selected for this study. They were undergoing full-bonded non extraction treatmentwith metal brackets (Roth 0.22, Discovery Dentaurum) on their teeth and bands on their molars.Each patient was provided with a toothbrush and toothpaste. The mouthwashes were used bypatients according to the manufacturersAE directions 15 min after toothbrushing: 5 mL of 0.2% CHX(Corsodyl, GlaxoSmithKline) was applied for 60 s in the morning and before bedtime for 2 weeks.Results: The data were analyzed according to the nonparametric Wilcoxon signed rank test (SPSSsoftware). Statistical significance level was set at p

Objective. The aim of this study was to evaluate the influenceof candida infection on denture stomatitis. Patients andMethods. Our study included 90 examinees of both sexes andall of them were wearers of mobile prosthetic devices for atleast a year. On the basis of the anamnesis data and clinicalcheck-up, the examinees were divided into 6 groups. In themethodology framework palate and denture plate scrapingswere taken. For identification of Candida albicans and nonalbicansCandida species the blastesis (germ) test, cultivationon the chromo-phyl base (Chrom agar) and the Candidaassimilation test (API test) were used. Results. The resultsshowed that denture stomatitis was detected in 50% of thecases. The proof of the interrelation between Candida albicansand denture stomatitis is the highly significant positivepalate culture finding to Candida albicans and the dentureplate culture finding. Conclusion. Denture stomatitis is a localdeterminant for stronger adherence of Candida albicanswith consequent pathologic implications for the oral mucousmembranes.

The constantly present dilemmas concerning the existence/non-existence of a relationship between bone density andperiodontal disease gave us the idea to do this research. Ourstudy covered 128 female patients in post menopause whowere, on the basis of their densitometry findings, divided intothree groups (healthy, with osteopenia, with osteoporosis).All the patients under research were clinically examined anddental X-rayed (orthopantomogram). Results were processedstatistically and compared to the relevant reference data. Onthe basis of the obtained results we came to the conclusionthat there is a relationship between periodontal disease andsystemic osteoporosis.
