Subcutaneous Emphysema of Periorbital and Canine Space Following Endodontic Treatment.

Emphysema of the subcutaneous tissue is an uncommon complication of dental procedures. Certain dental surgical procedures, such as extraction of teeth using air-driven handpieces and endodontic procedures are more prone to cause subcutaneous emphysema. Subcutaneous emphysema is typically self-limiting and only in a few instances has an impact on the long-term health of the patient.

Clinical Evaluation of Modified Technique of Alar Base Cinch Suture to Prevent Widening of Alar Base.

Introduction: Following Lefort I osteotomy, widening of the alar base is the most common secondary postoperative change resulting in deepening of the alar facial groove, which may be unaesthetic. Therefore, various surgical techniques to control lateralization of the alar base have been widely described in the literature. The purpose of this study was to analyze the cause and to prevent the changes in the nasolabial region, especially excessive widening of the alar base following Lefort I osteotomy by using modified alar base cinch suture.

Evaluation of healing by Cone Beam Computed Tomography (CBCT) using Platelet-Rich Plasma (PRP) + β -Tricalcium Phosphate (β -TCP) and Platelet Rich Fibrin (PRF) + β -Tricalcium Phosphate (β - TCP) in periapical lesions: Case report.

When teeth have responded poorly to conventional endodontic treatment or when they cannot be treated adequately by nonsurgical means, surgical endodontics remains the treatment of choice. Healing of apical lesions occurs by repair, most of the time. "Repair is the healing of a wound by tissue that does not fully restore the architecture or function of the affected unit".

Association of COL1A2 (PvuII) gene polymorphism with risk and severity of dental fluorosis - A case control study.

Introduction: Dental fluorosis is a foremost public health problem in many countries, including India. Very few studies investigated gene polymorphism and risk of dental fluorosis. Genetic polymorphisms in Collagen Type I, alpha 2 (COL1A2) gene, found to be linked with bone pathogenesis, may affect the tooth formation resulting in the vulnerability to dental fluorosis.

Versatile midfacial degloving approach in oral and maxillofacial surgery.

Objectives: Oral and maxillofacial surgeons must gain mastery of various approaches to the midface due to the increasing incidence, complexity, and severity of presenting midfacial fractures. Unlike in the case of other body parts, the need to preserve facial aesthetics makes it more difficult for the surgeon to select an approach for managing the facial injuries. The midfacial degloving (MFD) approach is a combination of intraoral and intranasal incisions made to access the midface without any external incision.
