Dentigerous cyst is the most frequently encountered odontogenic cyst which is epithelial lined and is developmental in origin. It usually affects young males below 30 years of age. Thus, its early diagnosis and treatment with rehabilitation becomes very important. Here a series of three cases with rare involvement of impacted maxillary lateral incisor, maxillary premolar and mandibular canine i...

In this clinical report, we discuss the length of service and subsequent replacement of a maxillary anterior 2-unit cantilever fixed partial denture (FPD). The FPD provided 53 years of service to the patient and was finally replaced with a 2-unit porcelain-fused-to-metal (PFM) FPD. The original prosthesis replaced a missing maxillary lateral incisor using a partial coverage metal retainer, wher...

INTRODUCTION The purpose of this study was to evaluate differences in periodontal status, root length, and visual assessment in patients with palatally impacted maxillary canines that were surgically exposed, allowed to erupt freely into the palate, and orthodontically aligned. METHODS Clinical examinations of the maxillary lateral incisors, canines, and adjacent premolars were performed on 1...

A 20-year-old man presented with the history of pain and swelling in the anterior maxillary segment. The periapical radiography was indicative of a dental anomaly in right maxillary lateral incisor. Due to the insufficient information from conventional radiography, cone-beam computed tomography (CBCT) was ordered. CBCT showed apical root resorption, large apical lucency and two separate canals ...

Congenitally missing teeth are frequently presented to the dentist. Interdisciplinary approach may be needed for the proper treatment plan. The available treatment modalities to replace congenitally missing teeth include prosthodontic fixed and removable prostheses, resin bonded retainers, orthodontic movement of maxillary canine to the lateral incisor site and single tooth implants. Dental imp...

a 16 year old female was referred to an oral and maxillofacial radiologist for evaluation of a radiolucent area at mesial radicular aspect of right maxillary central incisor which was detected accidentally during pre-orthodontic treatment check ups. clinical examination showed no particular signs or symptoms except for slightly tenderness to lateral percussion. second radiograph with altered ho...

OBJECTIVE The aims of this study were to investigate the frequency and characteristics of dental transpositions and to evaluate associated dental anomalies in a large sample of Turkish Anatolian population. STUDY DESIGN A retrospective study was performed using panoramic radiographs of 6983 patients (4092 females and 2891 males) ranging in age from 12 to 27 subjected to Faculty of Dentistry a...

Understanding of tooth eruption in humans remains incomplete. We hypothesized that genetic factors contribute significantly to phenotypic variation in emergence of primary incisors. Modelfitting was applied to data from Australian twins to quantify contributions of genetic and environmental factors to variation in timing of emergence of human primary incisors. There were no significant differen...

this report describes the non-surgical treatment of an invaginated maxillary lateral incisor with two fused roots. the mesial root had a c-shaped canal, while the distal one had a type iii dens invagination. cone-beam computed tomography (cbct) was used to help with the diagnosis and treatment decision making. clinical and radiographic follow-up revealed satisfactory periapical repair and absen...

This research used the spectroradiometer (Pritchard Model 1980 B) to measure the spectral radiance factors of women's maxillary anterior teeth. The following conclusions were reached: 1. The spectral distributions of the anterior teeth were all similar at the cervical, middle, and incisal areas respectively. Their spectral distributions ran in parallel at an almost equal distance, with the curv...
