Retromolar space has long been identified as a major factor in the aetiology of mandibular third molar impaction. The aims of this study were to compare mandibular third molar space between the different antero-posterior (A-P) skeletal patterns, between erupted and impacted third molars in the different A-P skeletal patterns, and to report on the status of third molar eruption/impaction among t...

. AbstrAct Gender determination of skeletal remains is a part of many medico-legal as well as anthropological examinations. Many anatomical structures have been studied, but the teeth and their measurements seem to be the most reliable method since teeth represent the most durable and resilient part of the skeleton. The purpose of this study was to investigate the accuracy of a method with whic...

Tongue enlargement and mandibular prognathism are clinically recognized in almost all patients with acromegaly. An acromegaly-like rat model recently developed by exogenous administration of insulin-like growth factor I (IGF-I) was used to investigate morphological and histopathological changes in orofacial structures and to clarify whether these changes were reversible. Exogenous administratio...

ObJECTivE: To evaluate and compare the effectiveness of rapid maxillary expansion (RME) and slow maxillary expansion (SME). MaTERiaLS aND METHODS: PubMed, Embase, Web of Science, CENTRaL, ProQuest Dissertations & Theses, ClinicalTrial.gov, and SiGLE were searched from January 1980 to October 2012 for randomized or nonrandomized controlled trials. The processes of study search, selection, and qu...

OBJECTIVE The aim of this study was to analyze the dental and alveolar intercanine, interpremolar and intermolar widths in patients with Class II/2 malocclusion and to compare the data with a patient group with normal occlusion and also with a patient group with Class II/1 malocclusion. MATERIALS AND METHODS The study was conducted on 140 untreated patients with permanent dentition, aged 16 t...

The purpose of this article is was to introduce a mathematical model, investigating the anticipated changes in intercanine width associated with the resolution of crowding, using the leeway space. A linear regression formula was computed to predict the change per millimetre of 'intercanine tip space deficiency'. After digitizing 61 mandibular casts, 14 co-ordinates per model were used to fit an...

Primary canine hypoplasia (PCH) is an enamel defect located on the mesial aspect of the facial surface at approximately the junction of the gingival and the middle thirds of the tooth. 1-5 The defect exists in two forms: minimal hypoplasia consisting of brown, white, or yellow opaque areas with a smooth surface; and obvious hypoplasia having a combination of pitting, invagination, missing ename...

OBJECTIVE The aim of this study was to verify, in vivo and in vitro, the prevalence of root canal bifurcation in mandibular incisors by digital radiography. MATERIAL AND METHODS Four hundred teeth were analyzed for the in vivo study. Digital radiographs were taken in an orthoradial direction from the mandibular incisor and canine regions. The digital radiographs of the canine region allowed v...

Objectives To assess the relationship between dental follicle width and maxillary impacted canines' descriptive and resorptive features with three-dimensional (3D) cone-beam computed tomography (CBCT). Methods The study comprised 102 patients with cone-beam computed tomography 3D images and a total of 140 impacted canines. The association between maxillary impacted canine dental follicle widt...
