UNLABELLED The radicular groove is a developmental anomaly that predisposes the tooth to periodontal break-down. Sometimes the situation becomes more complicated by pulp necrosis and development of a combined endodontic-periodontal lesion which is a diagnostic and treatment challenge for the clinician. This report presents the successful management of an endodontic-periodontal lesion in a maxil...

INTRODUCTION Clinicians are regularly confronted with difficult choices. Should a tooth that has not healed through nonsurgical root canal treatment be treated through endodontic microsurgery or be replaced using a single implant? Acquiring complete, unbiased information to help clinicians and their patients make these choices requires a systematic review of the literature on treatment outcomes...

PURPOSE Subcutaneous emphysema arises when air is forced beneath the tissue, leading to swelling, crepitus on palpation, and potential to spread along the fascial planes. The goal of this literature review is to alert the oral and maxillofacial surgeon to the inciting factors, diagnosis, and management of subcutaneous emphysema. PATIENTS AND METHODS A comprehensive search of the medical and d...

The aim of this in vitro study was to evaluate the influence of endodontic therapy, veneer preparation, and their association on fracture resistance and deflection of pulpless anterior teeth and assess whether restoration with quartz fiber-reinforced post can influence these properties. Seventy-five freshly extracted human maxillary central incisors were selected. Teeth were randomly divided in...

INTRODUCTION This retrospective study examined the potential prognostic factors on the outcome after endodontic microsurgery and compared the predictors of isolated endodontic lesion with those of both isolated endodontic lesions and endodontic-periodontal lesions. METHODS The data were collected from patients with a history of endodontic microsurgery performed between August 2004 and Decembe...

The hazard of surgical smoke is often overlooked when considering the safety medical laser procedures but can present a high level occupational risk. Administrative for operating external extraction devices and reliance on personal protective equipment are not sufficient reducing This paper aims to quantify laser-generated demonstrate how effective engineering control solutions reduce A new des...

INTRODUCTION Endodontic-periodontal combined lesion is a clinical dilemma because making a differential diagnosis and deciding a prognosis are difficult. METHODS Twenty-six cases from 14 articles involving the successful management of endodontic-periodontal lesions with concurrent regenerative procedures were reviewed. This article also presents successful treatment of an endodontic-periodont...

Success of endodontic treatment requires the knowledge and morphology of root canal anatomy. Undetected additional canals in mandibular premolar is a common reason for endodontic failure. This presents with diagnostic difficulty and subsequent flare ups and poor prognosis. Location of additional canals is the key to successful endodontic management. This case report describes endodontic managem...

High-pressure air enters the air-turbine of the dental handpiece and strikes the blades to drive the impeller. The air-turbine has impeller and the air tube is connected to the air-turbine housing. The flowfield of the air-turbine were investigated for the optimum air-turbine design using ANSYS CFX. The objective of the research was to find an optimum design variables for the air-turbine to inc...
