Objectives: The purpose of present study was to assess the surgical management of impacted third molar with proximity to the inferior alveolar nerve and complications associated with coronectomy in a series of patients undergoing third molar surgery.
Material And Methods: The position of the mandibular canal in relation to the mandibular third molar region and mandibular foramen in the front part of the mandible (i.e., third molar in close proximity to the inferior alveolar nerve [IAN] or not) was identified on panoramic radiographs of patients scheduled for third molar extraction.
Results: Close proximity to the IAN was observed in 64 patients (35 females, 29 males) with an impacted mandibular third molar. Coronectomy was performed in these patients. The most common complication was tooth migration away from the mandibular canal (n = 14), followed by root exposure (n = 5). Re-operation to remove the root was performed in cases with periapical infection and root exposure.
Conclusions: The results indicate that coronectomy can be considered a reasonable and safe treatment alternative for patients who demonstrate elevated risk for injury to the inferior alveolar nerve with removal of the third molars. Coronectomy did not increase the incidence of damage to the inferior alveolar nerve and would be safer than complete extraction in situations in which the root of the mandibular third molar overlaps or is in close proximity to the mandibular canal.

Statement Of The Problem: Root canal preparation with rotary files causes dentinal cracks in root canals of primary teeth affecting their longevity.
Purpose: Nickel-titanium rotary files have been widely used for root canal preparation in primary teeth. The present study compared occurrence of dentinal microcracks in root canals of extracted primary molar teeth prepared using Hedstrom (H) files, ProTaper Universal rotary files, and ProTaper Next rotary file systems.

Statement Of The Problem: Dentin bonding with etch-and-rinse adhesives involves demineralizing the 5-8µm of the surface dentin to create micro space for resin infiltration. The presence of continuous fluid movement in dentin tubules and positive pulpal pressure prevents complete water replacement by resin monomers. This results in areas of demineralized dentin, which contain collagen fibers without resin infiltration.

This case report describes the management of a 31-year-old male with a large hemangioma of the tongue and pharynx undergoing surgical extraction of mandibular third molars under intubated general anesthesia. Despite taking precautions and avoiding traumatizing the hemangioma while securing the airway, massive bleeding occurred during the surgical extractions, which prompted emergent transfer for angiographic embolization and a stay in the intensive care unit until extubation.

The analgesic efficacy and safety of liposomal bupivacaine (LB) in third molar extraction was evaluated in this phase 3, double-blind, placebo-controlled study of subjects undergoing bilateral third molar extraction. Subjects were randomized 2: 1 to infiltration with LB (133 mg/10 mL) or placebo, and received opioid rescue medication as needed. Primary efficacy measure was cumulative area under the curve (AUC) of numeric rating scale (NRS) pain severity scores through 48 hours (AUC of NRS0-48) postsurgery.
