BACKGROUND: The surgical extraction of the third molar is the most frequently encountered procedure in oral and maxillofacial surgery and is related with a variety of complications. This study examined the efficacy of intentional partial odontectomy (IPO) in the third molars which have no periapical lesions and are located near important anatomical structures such as inferior alveolar nerve. METHODS: Seven patients (four males, three females, 39.1 ± 11.6 years), who received IPO to reduce the risk of inferior alveolar nerve injury (IANI), were followed long-term...

The restoration of normal function and esthetic appearance with a dental prosthesis is a major challenge in the rehabilitation of patients who have lost their teeth and surrounding bone because of surgery for oral cyst or tumor. Rehabilitation with fixed or removable prosthesis is even more challenging when the edentulous span is long and the ridge is defective. Anatomic deformities and unfavorable biomechanics encountered in the region of resection add to the misery. In such situation, a fixed-removable prosthesis allows favorable biomechanical stress distribution along with restoration of esthetics, phonetics, comfort, hygiene, and better postoperative care and maintenance...

AIM: Periodontists frequently experience inconvenience in accurate assessment and treatment of furcation areas affected by periodontal disease. Furcation involvement (FI) most commonly affects the mandibular molars. Diagnosis of furcation-involved teeth is mainly by the assessment of probing pocket depth, clinical attachment level, furcation entrance probing, and intraoral periapical radiographs. Three-dimensional imaging has provided advantage to the clinician in assessment of bone morphology...

INTRODUCTION: To evaluate fracture healing in mandible of rats under zoledronate therapy. METHODS: A total of 135 Wistar rats were randomly allocated into 3 groups. Group L received two intravenous infusion of 0.06 mg/kg zoledronate 6 weeks apart. Group H received the same dose of zoledronate as group L once a week for 6 weeks and group C were treated with normal saline. Seven days after the last infusion, rats underwent unilateral mandibular osteotomy to replicate a fracture...

INTRODUCTION: Lingual nerve damage is one of the common complications following mandibular third molar surgery. On considering the impact of lingual nerve damage on the patient's quality of life, it is necessary to exercise caution to minimize its occurrence. MATERIAL AND METHODS: Although many lingual retractors are available, in this article we describe an indigenously designed lingual retractor for use in mandibular third molar surgery. CONCLUSION: The indigenous lingual retractor described in this article provides advantages like clear access and excellent retention unlike conventional retractors...

BACKGROUND: Microorganisms may invade the blood stream by oral routes through surgical procedures like extractions, fractured teeth and periodontal pockets. The incidence of bacteremia is 70-80 % following tooth extraction, sub gingival scaling and intra ligament injection. AIMS AND OBJECTIVES: Aim of study was to evaluate and compare the efficacy of two topical antimicrobial agents for the prevention of post-surgical bacteremia during mandibular third molar surgery...

The aim of this study is to investigate the position and course of the mandibular canal through the ramus, angle and body of mandible using computed tomographic (CT) imaging pre-operatively and to relate these predetermined values intra-operatively to perform sagittal split ramus osteotomies. Pre-operative CT scans were taken and four points were marked at mandibular foramen, mandibular angle, mandibular body and midpoint and different dimensions of IAN were measured to localize the inferior alveolar nerve...

INTRODUCTION: Apical surgery on the separate distolingual (DL) root of a 3-rooted mandibular first molar is thought to be difficult because DL roots are always severely curved, small, and shorter than distobuccal (DB) roots, and they are located far from the buccal cortical bone. The purpose of this study was to use cone-beam computed tomographic images to investigate the apical surgery-related morphological characteristics of DL roots in a Chinese population. METHODS: The screening process identified 83 subjects with 128 mandibular first molars with separate DL roots...

OBJECTIVE: The aim of this study was to determine whether patients with a pain score ≥7 (high pain group) after a mandibular block injection had a higher physiologic response compared with patients with scores <7 (low pain group). STUDY DESIGN: Before oral surgery, patients (n = 66) filled out questionnaires to measure anxiety and expected pain. The questionnaires also assessed patients' experiences with dental injections and dental anxiety, as well as their emotional state and intensity of anxiety...

INTRODUCTION: Cutting and drilling guides manufactured using computer-aided design/computer-aided manufacturing (CAD/CAM) technologies have attracted increasing interest in orthognathic surgery, particularly in complex cases. The development of these guides requires virtual surgery planning and three-dimensional modelling before they can be printed in titanium, polyamide, or resin. We report the use of a personalized titanium device to assist bilateral sagittal split osteotomy (BSSO) with or without genioplasty combined with individual implants for repositioning and fixation...

BACKGROUND: Pierre Robin sequence (PRS) is a triad of micrognathia, glossoptosis, and respiratory distress. There is no standard clinical classification used in the management of neonatal airway in patients with PRS. The goal of our study was to review the presentation and management of patients with PRS and formulate a clinical grading system and treatment algorithm. METHODS: A 10-year retrospective review of all neonates diagnosed with PRS was performed after obtaining institutional ethics approval...

OBJECTIVE: The aim of this study was to evaluate the effect of phototherapy on bite force, facial swelling, mandibular movements, and pain in patients having undergone surgical treatment for mandibular fractures. BACKGROUND: These are among the predominant types of facial fractures, and treatment involving surgical fixation with titanium plates is one of the most common procedures in oral-maxillofacial surgery. Phototherapy has been used to accelerate the muscle healing process and significantly improves muscle regeneration by inducing the formation of new muscle fibers...

PURPOSE: To performed a histomorphometric and radiological study to evaluate the effects of alendronate sodium administered locally in mandibular bone defects created in rabbits. METHODS: Two circular defects 5 mm in diameter were created bilaterally in the mandibular corpus of 20 New Zealand rabbits (i.e., four defects per animal). Each defect received one of four treatments: no treatment (EC group), alendronate irrigation (AL group), autogenous bone grafting (AG group), or alendronate irrigation with autogenous bone grafting (AL+AG group)...

BACKGROUND: The authors updated a previously published systematic review to assess the effects of low-level laser therapy (LLLT) on reducing complications after the removal of impacted mandibular third molars. TYPES OF STUDIES REVIEWED: The authors searched for randomized clinical trials in which the investigators evaluated the efficacy of LLLT compared with that of placebo or no treatment. Two reviewers independently screened studies, extracted data, and assessed risk of bias...
