INTRODUCTION The purpose of this study was to evaluate the skeletal and dental changes in patients who underwent distalization of their maxillary molars with pendulum appliances. METHODS The sample consisted of 31 patients (initial mean age, 14.58 years) with Angle Class II molar relationships and all permanent teeth up to the second molars. The maxillary molars were distalized with pendulum ...

OBJECTIVES The purpose of this study was to investigate the incidence of root fusion and C-shaped root canals in maxillary molars, and to classify the types of C-shaped canal by analyzing cone-beam computed tomography (CBCT) in a Korean population. MATERIALS AND METHODS Digitized CBCT images from 911 subjects were obtained in Chosun University Dental Hospital between February 2010 and July 20...

As PART of a study of spacing-crowding at the Burlington Orthodontic Research Centre, cognisance was taken of the presence of mesial and distal restorations in primary molars in the sample. Since at age nine, more than half the sample of primary molars which could be measured had such restorations, the validity of the spacingcrowding data could be questioned. Specifically, it was of interest to...

The modification of the col shape and position by the restorative alveolar interface technique (RAI) was studied in the interproximal areas between the mandibular first molars and fourth premolars of 10 dogs. Full thickness flaps were raised to expose the interproximal root surface and alveolar bone crest. The RAI procedure was performed only on the experimental sides and the control areas were...

Abrasion of dental crown and the shape of denture occlusal surface are significant indicators in age determination of domestic mammals. The factors that significantly influence age determination of Eneolithic deer game in conditions of an open wildlife habitat are climatic changes that influenced their survival, as well as specific features of teeth morphological structure. In this paper the ag...

INTRODUCTION The purpose of the present study was to evaluate the prevalence of bilateral three-rooted mandibular first and second molars in Indian population. MATERIALS AND METHODS A total of 215 patients were screened bilaterally for mandibular first and second molar and 430 samples of periapical radiographs were obtained. The gender, symmetry, and prevalence of three-rooted mandibular firs...

The influence of diet and fluoride on odontogenesis in rats was investigated. 20 foetuses, 20 days old, were divided into four groups. The control group was fed with the standard diet and drank water with 0.16 mg F/l. The second, third and fourth groups were fed with the deficit, experimental diet and drank distilled water with 10 and 110 mg of natrium fluoride per litre or without fluoride. In...

The aim of the present study was to investigate the relationship between developmental changes in sagittal occlusion and the presence of caries on the occlusal surface of the lower first permanent molars. Dental casts were taken from 60 children at 2-monthly dental examinations after the emergence of the lower first molars through to when they reached 22 years of age. Data on the state of the o...

Relapse after orthodontic tooth movement (OTM) is an undesirable outcome that involves a number of factors. This study investigated the remodelling of the alveolar bone and related periodontal structures during orthodontic relapse in rat molars. The maxillary right first molars of 35 Wistar rats were moved mesially by a fixed orthodontic appliance for 10 days and the contralateral molars served...

AIM: This study aims to investigate effect of mandibular third molars on angulation second and canines.
 MATERIAL AND METHOD: A total 16 patients (10 female, 6 male) were included. All had two panoramic radiographs. available in the first radiograph. The radiograph was taken approximately 124.81 ± 21.63 weeks after one-sided molar extraction. angulations canines measured These evaluated ex...
