The partial labyrinthectomy petrous apicectomy (PLPA) approach is a transpetrous route that provides the advantages of the labyrinthine removal but with hearing preservation. Using seven temporal bone tissue blocks and three formaldehyde-fixed cadaveric heads we have made a morphometric and comparative study on this approach that summarizes the invasiveness, the optimal surgical exposure, the a...

INTRODUCTION Almost the entire human creativity today, from the standpoint of its efficiency and expediency, is conditioned with the existence of information systems. Most information systems are oriented to the management and decision-making, including health information system. System of health and health insurance together form one of the most important segments of society and its functionin...

This study investigated the effect of doxycycline irrigation on wound healing and the apical seal of three filling materials. Part 1: 220 extracted teeth received root canal therapy followed by root resection (2 mm) and ultrasonic root end preparations (3 mm). Groups of 20 were irrigated with saline, citric acid, or doxycycline and filled with amalgam, Super EBA, or MTA. Leakage was measured (m...

AIM The objective of this study was to radiographically assess and compare the quality of post-retained crowns fabricated at the Dental Health Centre of the Jordan University of Science & Technology (JUST). METHODS AND MATERIALS Study data were collected in 2002 from existing dental records for all patients receiving treatment with post-retained crowns between October, 1997 and June, 1999. Th...

Biomaterials such as membrane barriers and/or bone grafts are often used to enhance periapical new bone formation. A combination of apical surgery and these biomaterials is one of the latest treatment options for avoiding tooth extraction. In case of periapical lesions, guided tissue regeneration (GTR) is attempted to improve the self-regenerative healing process by excluding undesired prolifer...

BACKGROUND/AIM Suture materials play an important role in healing, enabling reconstruction and reassembly of tissue separated by the surgical procedure or trauma, and at the same time facilitating and promoting healing and hemostasis. Suture materials are used daily in oral surgery, and are considered to be substances most commonly implanted in human body. The aim of this clinical study was to ...

INTRODUCTION Procedural accidents have a negative effect on healing and might contribute to the persistence of infections in inaccessible apical areas, requiring surgical intervention. This report describes a case of persistent apical periodontitis of a lower left first molar associated with the sinus tract and a periapical lesion that required nonsurgical endodontic retreatment and apical surg...

INTRODUCTION It is imperative that the endodontic surgeon be knowledgeable of the anatomic dimensions of the surgical site. If cone-beam computed tomography is not available because of location/cost, it is prudent for the clinician to consult a knowledge base for the surgical site. An understanding of the root thickness of maxillary premolars and molars at the preferred level for root resection...

as gray-yellowish necrotic material. Necrotic material is not observed in an intact cystic lesion, such as a dentigerous cyst. This material was probably keratin, which is not produced in dentigerous cysts 3. Although the diagnosis is established solely after histo-pathological analysis, some imaging features presented in this case are more likely to indicate OKC. Radiolucencies distal to the t...

Finite element analysis (FEA) is an engineering method for the numerical analysis of complex structures based on their material properties. It is used to determine the distribution of stress when a structure is subjected to force. Recently, FEA has been employed in endodontic. Endodontic diseases, such as pulpits or periradicular periodontitis, often require root canal therapy. During or after ...
