OBJECTIVE A study is made of the efficacy of the Erbium:YAG laser in granulomatous periapical lesions, based on clinical and radiographic controls. MATERIAL AND METHODS The study comprised a series of 45 patients amenable to periapical surgical treatment of incisors, canines and premolars. A conventional surgical technique was used, with silver amalgam retrograde filling and irradiation of th...

JADA 142(6) http://jada.ada.org June 2011 651 A45-year-old woman visited her general dentist because of severe pain in the right mandibular posterior region. Her first molar contained a large mesialocclusal-distal amalgam restoration, and the patient experienced symptoms consistent with irreversible pulpitis. In addition, radiographs showed changes associated with the mesial root. The second mo...

Abstract:
 Aim: to evaluate the bone healing in failed endodontically treated teeth after surgical removal of periapical lesions and placement hydroxyapatite (HA), nanohydroxyapatite (nHA) a combination with platelet rich fibrin (PRF) periapically. Subjects methods: study was conducted on twenty-four patients having radiolucency single rooted teeth. The selected were divided into three gro...

INTRODUCTION The fusion of permanent teeth is a development anomaly of dental hard tissue. It may require a hard multidisciplinary approach with orthodontics, endodontics, surgery and prosthetics to solve aesthetic and functional problems. CASE PRESENTATION A 20-year-old Caucasian man presented to our Department to solve a dental anomaly of his upper central incisors. An oral investigation re...

Posterior atlantoaxial (C1-2) fixation with individual screw placement in C1 and C2 has been one of the technical options to treat C1-2 subluxation or instability. In the present study, we demonstrate the surgical technique of C2 nerve root resection to avoid the troublesome bleeding from the perivertebral venous plexus and achieve full exposure of the lateral C1-2 joints. The present study inc...

Purpose: The treatment for furcation involvement is a great challenge to the general dentists. Tunneling may be a treatment alternative for class II and III furcation involvements in mandibular molars with large angle separation and great divergence between the mesial and distal roots. This alternative is a conservative treatment that allows a great condition to oral hygiene maintenance by the ...

Traditionally, when a root-originated fracture (ROF) was diagnosed in an endodontically treated tooth, the tooth was scheduled for extraction. However, modern endodontics offers new treatment options to manage and maintain certain ROF teeth. The decision of whether to extract a ROF tooth and substitute it with a dental implant, or to implement a more conservative management approach by attempti...

Root resection is the process by which one or more of the roots of a tooth are removed at the level of the furcation while leaving the crown and remaining roots in function [1]. Indications for root resection therapy include: teeth with periodontal problems, endodontic problems, root fractures, and prosthetic problems [2]. Vertical root fracture (VRF) is an untoward complication to root canal t...

All patients in this study were referred to the Hospital of Stomatology, Fujian Medical University, Fujian, China, for orthodontic consultation between 2004 and 2014. Nolla’s method was utilized to determine each patient’s dental age.15,16 A tooth with only one-third (stage 7) or two-thirds (stage 8) of its root formation was assigned to the early dental-age group; a tooth with an almost comple...

Background and Objectives: The most recent technological breakthroughs incorporated in the latest generation of Variable Square Pulse (VSP) Er:YAG dental lasers involve two additional features: SSP (Super Short Pulse) mode for extremely fine and minimally invasive laser ablation; and MAX mode for maximum optical drilling speeds. The objective of this study was to make a comparison between the t...
