For the second premolar, the average distance to the IANC was 0.88-13.03 mm for males and 0.00-5.49 mm for females. The average distance of IANC to the mesial root apex of first molar was 1.46-13.23 mm for males and 0.93-8.03 mm for females. For the second molar, the average distance was 1.31-14.71 mm for males and 0.00-6.91 mm for females (values on left side were shorter as compared to right side). In the overall population, only second molar exhibited significant difference in the distance from root apex to IANC when compared bilaterally. In addition to gender differences, age-related differences were found to be significant for the first molar on left side and second molar on the right side of the population (P< 0.05).

Within the parameters of this study, a combination of platelet-rich fibrin and PPP demonstrated higher number of viable PDL cells and hence could be a good biologic rejuvenating media for avulsed teeth.

Periapical surgery is required when periradicular pathosis associated with endodontically treated teeth cannot be resolved by nonsurgical root canal therapy (retreatment), or when retreatment was unsuccessful, not feasible or contraindicated. Endodontic failures can occur when irritants remain within the confines of the root canal, or when an extraradicular infection cannot be eradicated by orthograde root canal treatment. Foreign-body responses toward filling materials, toward cholesterol crystals or radicular cysts, might prevent complete periapical healing. We present here a case report wherein, combination of platelet-rich fibrin (PRF) and the hydroxyapatite graft was used to achieve faster healing of the large periapical lesion. Healing was observed within 8 months, which were confirmed by computed tomography, following improved bone density. PRF has many advantages over platelet-rich plasma. It provides a physiologic architecture that is very favorable to the healing process, which is obtained due to the slow polymerization process.

Objective:The objective of this study is to evaluate the fracture resistance of newer restorative materials that could serve as an alternate to crown coverage.Materials and Methods:Forty extracted human mandibular molar teeth were selected for this study and were divided into four groups (n = 10). All the teeth in the experimental groups (Group 2–4) were subjected to access cavity preparation with roughly 1.5 mm of tooth structure remaining throughout the circumference. Group 1: Intact teeth used as control. Group 2: Access cavities reinforced with biodentine. Group 3: Inner circumference of access cavities reinforced with polyethylene fiber and nano-hybrid composite. Group 4: Access cavities were reinforced with fiber reinforced composite. All the teeth were subjected to fracture resistance using universal testing machine.Results:The results of the study were evaluated statistically using one-way ANOVA and Tukey post hoc test. Group 2 demonstrated the least mean values of fracture resistance and was significantly different from the control and other experimental groups. Statistically significant difference among Groups 1, 3, and 4 was not found.Conclusion:Within the limitation of this in vitro study, it can be concluded that fiber reinforced composite and polyethylene fibers with nanohybrid composite could serve as an alternate to crown coverage.
