Our results showed a continuously increasing incidence trend of both basal cell and squamous cell skin carcinomas in the population of the city of Belgrade between 1999 and 2011. Adequate primary and secondary prevention would certainly be successful in reducing this type of cancer in the future.

Our results show a significantly decreasing trend of the incidence rate for lip cancers in the population of the city of Belgrade between 1999 and 2010. On the contrary, the incidence of oral cavity and pharyngeal cancers increased for both men and women.

Within the limitations of this experimental animal study, it may be concluded that the type of surgery (flap or flapless) affects peri-implant bone preservation and osseointegration of regular platform implants. Flapless surgery is associated with peri-implant crestal bone preservation. Flapless surgery in combination with submerged implants allows higher osseointegration values.

Age-related cataract is a slowly progressive disease, and its appearance probably reflects the cumulative action of numerous causative factors over decades of life. Serum albumin concentration seems to be important in cataract development in some age-related cataract patients.

Increase in the number of mast cells in the infected gingiva can be correlated with an increased influx of inflammatory cells from blood circulation into the gingival stroma, as well as with the collagen lysis, since these cells produce substances with collagenolytic potential. Based on the distribution of mast cells, it could be concluded that in the evolution of periodontal disease there are significant dynamic alterations in migration and localization of these cells.

The diagnosis of macroglossia is based on subjective clinical criteria such as the morphology and amount of protrusion of the tongue, difficulty in articulating sounds, breathing, and hypersalivation. Some authors have suggested that the tongue size may be analyzed radiographically with a cephalogram. Treatment of macroglossia is controversial because of the absence of objective clinical criteria.

Background/Aim. This study aimed to examine the correlation of CBCT analysis derived bone density with primary stability value. Methods. Clinical prospective experimental study was conducted in 38 healthy patients missing one tooth in the lateral region. It was planned to install Bredent Blue Sky Narrow self-taping dental implants with dimensions 3.5 x 10 mm. During preoperative preparation, a CBCT scan was performed on Planmeca apparatus, followed by pre-implantation measurements and planning in the CBCT apparatus software (Romexis). The mean value of the average bone volume is automatically generated and expressed in Hounsfield units. Upon implant placement, we performed measurements of the primary implant stability using Osstell apparatus. Results. Of the thirty-eight patients included in the study, there were 68.4% male patients and 31.6% female patients. The arithmetic mean of the measured bone density of all subjects in the study amounted to 536.2 HU. The arithmetic mean of dental implant primary stability for all subjects in the study was 68.7 ISQ. There is statistically significant strong positive connection between HU and ISQ (r = 0.744, p <0.001). Higher HU values are connected to higher ISQ values. In the multivariate linear regression model, statistically significant predictors of higher ISQ values are as follows: male (B = 4.669; p = 0.047) and higher HU values (B = 0.032; p <0.001). Conclusion. We have shown in our clinical study that there is a statistically significant strong positive correlation between the bone density expressed in HU units measured in the software of the CBCT device and the primary stability of dental implants expressed in ISQ units.
