INTRODUCTION Literature reports on a method for dental age calculation which is based only on radiological measurements on periapical dental radiographs: the relationship between chronological age and the two-dimensional dental pulpal size was analysed by means of multiple regression analyses. The purpose of the present study was to evaluate whether this approach could be feasible and could lea...
With increasing age there are many changes in teeth such as attrition, peridontal disease, deposition of secondary dentine, root translucency, cementum apposition, root resorption, color changes, and increase in root roughness. By taking into consideration these secondary changes in teeth with advancing age, various studies were done to estimate the age of an individual. Such research has resul...
STATEMENT OF PROBLEMS Dental age can be estimated on the basis of the tooth mineralization level during the developmental process of the teeth. Among various radiological methods reported for the dental age determination in children, Demirjian method is widely used. PURPOSE To evaluate the applicability of Demirjian method in age estimation of the children aged 7-15 years in Babol, a northern...
BACKGROUND AND AIMS The aim of this study was to investigate the prevalence of permanent teeth extracted due to periodontal disease and its relation to age, military rank, and type of extracted teeth due to periodontal and non-periodontal reasons among a group of Greek Army personnel attending a military dental practice. MATERIALS AND METHODS Study population consisted of 509 officers, non-co...
Teeth are extremely useful in the estimation of age and are preferable over other skeletal methods As they are durable in archaeological contexts, have minimal remodeling, and the growth of permanent and deciduous teeth continues over the entire juvenile period [1,2]. Formation of deciduous teeth begins in utero at about 4 months and permanent teeth complete formation at approximately 25 years ...
BACKGROUND AND AIM: Recurrent caries is defined as caries in the marginal edges of filled teeth and is the most common reason for restoration replacement. The aim of this study was to evaluation of recurrent caries in amalgam, resin-based restorations and crowns in bitewing radiographies in patients who attended Kerman dental radiology centers, Iran.METHODS: This cross-sectional study conducted...
The aim of the present study was to obtain data on the reliability and reproducibility of two non-destructive dental-age estimation methods in adults by calculating inter- and intra-observer effects. Both a morphological and a radiological technique available in the scientific literature were evaluated on a number of recently extracted teeth: the morphological technique was evaluated on a total...
Introduction: Working length determination is important in successful endodontic treatment and retreatment.This study evaluated the accuracy of two electronic apex locators Root ZX and Raypex®6 (EALs) in determining the electronic working length (EWL) of the root canals in endodontic treatment and retreatment. Materials and Methods: Access cavities were prepared on forty extracted, singl...
