Trauma resulting in crown-root fracture is one of the most challenging fracture types. However, biologic width involvement should be carefully evaluated. Reattachment of tooth fragment to a fractured tooth remains as the treatment of choice because of its simplicity, natural esthetics, and conservation of tooth structure. The reattachment procedure using composite resin should be considered if the subgingival fracture can be exposed to provide isolation. This report presents a case of complicated crown-root fracture of permanent maxillay left central incisor, involving the biologic width in a 10-year-old girl. The traumatized tooth was treated endodontically. Access to the subgingival margins was gained by orthodontic extrusion followed by gingivectomy. The fractured fragment was reattached using bonding system and composite resin.

Peripheral ossifying fibroma (POF) represents a non-neoplastic, reactive lesion of gingiva. The precise etiopathogenesis of POF is unclear; however, it is suggested to originate from the connective tissue of periodontal ligament. This lesion predominantly occurs in the maxillary anterior region. The standard treatment protocol involves surgical excision followed by the biopsy of lesion. The reactive nature and unpredictable course attribute to a high recurrence rate of the lesion; hence, proper postoperative monitoring and follow-up of the lesion are necessary. The present case was surgically managed using diode laser and did not show any sign of recurrence during the follow-up period of 6 months. Minimum intraoperative bleeding and postoperative pain, ease of operation, and patient's acceptance enable laser-assisted growth excision as a better treatment modality to other conventional surgical procedures, thus offering diode laser as a viable and effective treatment alternative in the management of massive overgrowth.

We report a rare case of a two-rooted maxillary central incisor, stressing the importance of three-dimensional imaging in treatment planning and conservative approach of management. Endodontic treatment of this central incisor was carried out with a successful outcome.

Aim: To determine the clinical efficacy of biphasic hydroxyapatite+β-tricalcium phosphate (HA/β-TCP) alone or in the presence of collagen membrane (CM) in the management of intrabony defects. Materials and methods: Nineteen bilateral intrabony defects with an intrabony component ≥4 mm were selected and randomly allocated in a double-blind, split-mouth design to receive either HA/β-TCP+CM (test) or HA/β-TCP (control). Analytical parameters measured at baseline and 1 year after surgery included plaque index, gingival index, probing depth (PD), clinical attachment level (CAL), gingival recession (R), radiographic defect depth (RDD), and radiographic percentage bone fill (PBF). Results: One year after therapy, the test treatment resulted in statistically higher PD reductions (p < 0.001) and CAL gains (p < 0.001) than the control one. In the test group, all sites (100%) gained at least 3 mm of CAL, whereas in the control group only 10 sites (53%) gained CAL of ≥3 mm. The mean radiographic PBF calculated at the end of 1 year was found to be 41.3 ± 20.6% for the test group and 30 ± 20.5% for the control group, with a significant (p = 0.016) improvement in the PBF for the former. Conclusion: The present data appear to indicate that treatment with HA/β-TCP in combination with collagen barrier may result in higher clinical improvements than that achieved with HA/β-TCP alone.
