Application of platelet-rich fibrin and freeze-dried bone allograft following apicoectomy: A comparative assessment of radiographic healing.

Background: Apicoectomy conceptualizes surgically maintaining a tooth with an endodontic lesion that cannot be resolved by conventional endodontic (re-) treatment. To achieve this, continuous improvement in surgical techniques, materials and instruments is being done to enhance the outcome of periapical endodontic surgeries. The purpose of this study was to compare, radiographically, the healing kinetics of platelet-rich fibrin (PRF) and mineralized freeze-dried bone allograft (FDBA) in patients undergoing apicoectomy. Materials and Methods: Nineteen patients (aged 18-40 years) were included in the study and randomly assigned to groups A or B, where they received PRF or FDBA, respectively. Following apicoectomy, PRF gel and FDBA graft were prepared and placed in the osseous defect followed by placement of PRF membrane for graft stabilization and flap closure. Radiographic follow-up was done at the 1st, 3rd, 6th and 12th months for evaluation of healing using Molven's criteria. Statistical analysis was done with Pearson's and McNemar's Chi-square tests. Results: A highly significant difference (P = 0.002) in radiographic healing was observed at 6 months. Complete healing was observed in 50% of cases in Group A whereas in Group B, none of the cases presented with complete radiographic healing. However, at the end of 12 months, complete radiographic healing was observed in both groups. Conclusion: Our data suggest that PRF accelerates bone healing as compared to FDBA and is both time and cost-efficient.

Comparison of Radiovisiography, an Apex Locator and an Integrated Endomotor-inbuilt Apex Locator in Primary Teeth Endometrics.

Aim and objective: To compare the accuracy of radiovisiography (RVG), Root ZX mini Apex locator, and Endo radar's inbuilt Apex Locator during working length determination determination in primary teeth with the actual/direct canal length. Materials and methods: 58 primary teeth indicated for extraction in children of age group 4-12 years were selected. RVG, Root ZX mini Apex Locator, and Endo radar's Apex Locator were used to determine the working length intraorally. Following extraction of the teeth, the actual working length was determined with magnifying loupes (2.5×) using a K-file and an endodontic ruler. The data was tabulated and statistically analyzed. Results: 84 canals (58 teeth) were evaluated and Root ZX mini Electronic Apex Locator (EAL) showed no statistically significant difference with the actual measurement (p = 0.18) whereas Endo radar and RVG showed statistically significant difference. Endo radar underestimated, while RVG overestimated the working length. The most accurate method for working length measurements of the root canals in primary teeth was Root ZX mini EAL, followed by Endo radar and the least accurate was RVG. Conclusion: The Root ZX mini Apex Locator showed the most promising results and had an excellent degree of agreement with actual working length, followed by Endo radar and RVG.

Cheiloscopy and Dactyloscopy as Behavior Assessment Tool in Dental Settings: A Cross-sectional Study.

PURPOSE: Assessment of children's behavior in the dental setting and its correlation with thumb print and lip print. MATERIALS AND METHODS: The behavior pattern, lip print pattern, and thumb print pattern of 518 children aged 5-12 years were recorded in their first dental visit. The behavior pattern, lip print pattern, and thumb print pattern were determined using Frankl's Behavior Rating Scale, Tsuchihashi's classification, and Cummin's classification, respectively. The data were tabulated according to the classified criteria and statistically analyzed. RESULTS: It was observed that positive and definitely positive Frankl Behavior was associated with the children bearing an arch pattern of thumb print, whereas their lip pattern had no association with their behavior pattern, particularly in dental sittings. CONCLUSION: Thumb print pattern can aid as a behavior marker before a child's first dental appointment and this can prove beneficial for both the child and the clinician in providing a high quality of dental care and modify behavior for future dental appointments.
