BACKGROUND Leptin, initially described as an adipocyte-derived hormone to regulate weight control, is expressed in normal and inflamed human dental pulp, being up-regulated during pulp experimental inflammation. Leptin receptor (LER) has been identified in human periapical granulomas. The aim of this study was to analyze and characterize the expression of leptin in human periapical granulomas. ...

AIM To compare in an ex vivo model the ability of digital intraoral radiography and cone beam computed tomography (CBCT) to detect simulated external inflammatory root resorption lesions, and to investigate the effect of altering the degree of rotation of the CBCT scanners X-ray source and imaging detector on the ability to detect the same lesions. METHODOLOGY Small and large simulated extern...

Objectives: To find out the accurate prevalence of periapical pathology and to see the significance of the clinical signs in diagnosing each variant of periapical pathology. Methods: A study of 1000 patients chosen consecutively, who visited the department of oral radiology, for intraoral periapical radiographs. The clinical data of all the variants of periapical pathology were registered in a ...

Macrophages are major constituents of periapical granulomas. They have a central protective role in both innate immunity and adoptive, antigen-specific immune response. Macrophage activation may occur in periapical granulomas by cytokines produced by antigen-activated T-lymphocytes; by bacterial endotoxin, as part of the innate immunity; or by both these processes. Recent studies in athymic ani...

AIMS AND OBJECTIVES To conduct a survey of the current radiographic prescription practices among implant practitioners in the state of Kerala, India. METHODS 300 dentists were interviewed by employing a questionnaire which enquired about the radiographic evaluation methods prescribed by practitioners in implant site assessment in their implantology practice. Other reasons for choosing particu...

Image registration plays an important role in the diagnosis of dental pathologies such as dental caries, alveolar bone loss and periapical lesions etc. This paper presents a new wavelet based algorithm for registering noisy and poor contrast dental x-rays. Proposed algorithm has two stages. First stage is a preprocessing stage, removes the noise from the x-ray images. Gaussian filter has been u...

Periapical diseases are induced as a result of the direct or indirect involvement of oral bacteria. The etiologic factor being the degenerating pulp tissue. A periapical lesion is formed within an area of apical periodontitis which cannot form by itself and is inflammatory in origin. If the microbial etiology of periapical lesions and in the root canal is removed by nonsurgical root canal thera...

b a u c g picoectomy involves the surgical management of tooth with a periapical lesion which cannot be esolved by conventional endodontic treatment root canal therapy or endodontic retreatment). ecause the term “apicoectomy” consists of only ne aspect (removal of root apex) of a complex eries of surgical procedures, the terms “periapical urgery” or “periradicular surgery” are more approriate. ...

Before the advent of OPG and CBCT; Intraoral periapical radiography was mainstay of dental imaging since years. CBCT was rst adapted for potential clinical use in 1982 at the Mayo Clinic Biodynamics Research Laboratory. This technique is a recent development and is found to be more efcient and economical than conventional tomography or CT in oral diagnosis. CBCT allows better 3D visualisation...
