Background. Occlusal rims are used to determine the jaw relationships in the transverse and vertical dimensions and estimate the inter-occlusal distance in edentulous patients. It is important to find ways to determine the height and shape of the occlusal rims correctly. This study was undertaken to determine the exact distance from the oral cavity floor to the incisal edges of mandibular incis...

BACKGROUND Root resorption is one of the most common and undesirable sequelea of orthodontic treatment. The aim of this study was to evaluate the amount of root resorption in permanent incisors during 3 month active period of fixed orthodontic appliance therapy using periapical radiographs. METHODS Periapical radiographs of a total of 138 permanent teeth (n = 138, mandibular n1 = 52, maxillar...

AIM To investigate the root canal morphology of mandibular incisors in a Jordanian population using a canal staining and tooth-clearing technique. METHODOLOGY Four hundred and fifty extracted mandibular incisors were collected from dental clinics within north Jordan. Following pulp tissue removal and staining of the canal systems, the teeth were decalcified with 5% nitric acid, dehydrated wit...

Aim: To investigate the incisor wingings of the Southern Chinese and compare these with studies in different populations. Materials and Methods: The maxillary and mandibular incisor alignment in study casts of an unselected sample from a 12 year old Hong Kong Oral Health Survey of 12 year old children (n=459; 295 boys and 164 girls) were studied. Results: The prevalence of bilateral winging in ...

OBJECTIVE To assess the prevalence of severe external root resorption and its potential risk factors resulting from orthodontic treatment. METHODS A randomly selected sample was used. It comprised conventional periapical radiographs taken in the same radiology center for maxillary and mandibular incisors before and after active orthodontic treatment of 129 patients, males and females, treated...

PURPOSE The objective of this study was to assess the pattern of permanent teeth present in a self-selected sample of 17 female and 35 male patients with ectodermal dysplasia presenting for treatment with dental implants. METHODS Mean age of sample: 18.7 years, age range: 5.9 to 60.9 years. Panoramic radiographs were examined independently by two investigators to determine the permanent teeth...
