Treatment of an apical cyst with platelet concentrate - a case report.

Apical cysts are typically caused by dental pulp disease and are difficult to treat. In the majority of cases, surgical intervention is required. The rate of success after apical osteotomy varies between 60% and 91%. The introduction of platelet concentrates in treating chronic apical periodontitis is a promising direction for achieving quick and secure results. This article examines the healing of a sizable apical cyst after conservative surgical intervention and the application of platelet concentrate.

Television advertising and development of dental caries in children aged 6 to 12 years.

INTRODUCTION: Advertising today is increasingly seen to be targeting children as they can be easily persuaded. The influence on them is reinforced by children's difficulty in perceiving messages critically, in distinguishing the real from the imaginary, in their great confidence in messages from the media and popular characters and personalities, and in their inability to recognize risk and their propensity for imitation. AIM: The aim of the study was to investigate the impact of television advertising on children's nutritional preferences and the intensity of dental caries in children aged 6 to 12 years.Materials and methods: The study included 277 children (158 boys and 119 girls) aged 6 to 12 years from different schools in Sofia. A survey was used to assess the nutritional preferences of these children who are under the influence of watching television commercials. The DMF (T+t) index introduced by Klein, Palmer & Knutson (1938) was used to assess the intensity of dental caries. A correlation analysis was performed between the time spent watching TV and the development of dental caries. RESULTS: Many children buy on their own or ask their parents to buy advertised sweet candies, fizzy drinks and fruit juices, which are a risk factor for the development of dental caries. The results show that the longer they spend in front of the TV, the stronger the pronounced caries activity in children, supported by a statistically significant difference (p<0.001), Rho (277)=0.438. CONCLUSIONS: The studied children aged 6 to 12 years have unhealthy dietary preferences for low molecular weight carbohydrate foods, increasing their oral risk profile. Prolonged standing in front of the TV screen correlated with an increase in the intensity of dental caries in half of the children.

Caries Risk Assessment in Adults Using the Cariogram.

INTRODUCTION: This study identifies the caries risk in adult patients using the Swedish software product Cariogram. Early detection and timely management of risk factors for caries development are crucial for its prevention and non-operative preventative treatment. AIM: To identify patients at high risk for caries and implement a prophylactic program aimed at the individual patient based on the assessment of the individual risk factors. MATERIALS AND METHODS: The study included 59 women and 41 men aged 19-65 years. A detailed medical history was obtained from all patients who underwent thorough clinical examination, evaluation of saliva with Saliva-Check Buffer (GC) test and of Streptococcus mutans and Lactobacillus levels using the CRT Bacteria kit (Ivoclar Vivadent AG products), and assessment of the caries risk using the Cariogram software. RESULTS: The results showed that the most important risk factors were as follows: DMFT, (rs [100] = 0.358, p<0.001), levels of Lacto-bacilli (rs [100] = 0.321, p<0.001), levels of Streptococcus mutans (rs [100] = 0.302, p<0.05), plaque amount (rs [100] = 0.291, p<0.05), food intake frequency (rs [100] = 0.252, p<0.05), and diet content (rs [100] = 0.220, p<0.05). Insignificant correlation coefficients in risk assessment were shown by the application of fluorides (rs [100] = 0.114, p>0.05), saliva rate (rs [100] = 0.018, p>0.05), and saliva buffer capacity (rs [100] = 0.144, p>0.05). CONCLUSIONS: Cariogram is a very useful method in clinical practice for evaluation of the caries risk and its preventive, non-operative management.

Analysis of the causes of dental implant fracture: A retrospective clinical study.

OBJECTIVE: Fracture of osseointegrated dental implants is the most severe mechanical complication. The aim of the present study was to analyze possible causative factors for implant body fracture. METHOD AND MATERIALS: One hundred and one patients with 218 fitted implants and a follow-up period of 3 to 10 years were studied. Factors associated with biomechanical and physiologic overloading such as parafunctional activity (eg, bruxism), occlusion, and cantilevers, and factors related to the planning of the dental prosthesis, available bone volume, implant area, implant diameter, number of implants, and their inclination were tracked. The impact of their effect was analyzed using the Bonferroni-corrected post-hoc Mann-Whitney test for each group. RESULTS: The incidence of dental implant fracture was 2.3% in the investigated cases. Improper treatment planning, bruxism, and time of the complication setting in were the main factors leading to this complication. Typical size effect was established only for available bruxism, occlusal errors, and their activity duration. These complications were observed most often with single crown prostheses, and in combination with parafunctional activities such as bruxism and lack of implant-protected occlusion. CONCLUSION: Occlusal overload due to bruxism or inappropriate or inadequate occlusion as a single factor or a combination of these factors during the first years after the functional load can cause implant fracture. Fracture of the implant body more frequently occurred with single crowns than with other implant-supported fixed dental prostheses.
