INTRODUCTION The purpose of this study was to compare, in a split mouth design, the external apical root resorption (EARR) associated with orthodontic treatment in root-filled maxillary incisors and their contralateral teeth with vital pulps. METHODOLOGY The study sample consisted of 38 patients (14 males and 24 females), who had one root-filled incisor before completion of multiband/bracket ...

The area of the oral vestibule is often a place where pathologies appear (e.g., peripheral odontomas). The origin of these pathologies is not fully understood. In the present study, we traced a cell population expressing Sonic hedgehog (Shh) from the beginning of tooth development using Cre-LoxP system in the lower jaw of wild-type (WT) mice. We focused on Shh expression in the area of the earl...

To test the role of the miR17-92 (miR) cluster in dental bones, we evaluated the incisor tooth phenotype by micro-CT in 5- and 12-week-old conditional knockout (CKO) mice deficient in the miR17-92 cluster in type-I collagen-expressing cells and bone strength by finite element analysis. The incisor teeth of CKO mice showed a 23-30 % reduction in tissue volume and bone volume. Accordingly, the st...

BACKGROUND The aim of the study was to determine the root canal morphology of permanent mandibular incisor teeth in the Indian subpopulation with the use of cone beam computed tomography (CBCT). MATERIAL/METHODS CBCT images of 200 patients with 800 permanent mandibular incisors, fulfilling necessary inclusion criteria and aged 18 to 60 years were evaluated. The number of roots, number of root...

AIMS This article aimed to characterize the incidence of supernumerary teeth in Turkish children according to sex, location, number and morphology and to explore possible correlations between these variables. METHODS The study population comprised 7,551 non-syndromic patients aged 3-16 years who applied for routine check-ups at the Ankara University Department of Pediatric Dentistry between J...

Luxational injuries to the permanent anterior teeth in children are a cause of concern. Palatal luxation of maxillary left central incisor with bleeding of gingival sulcus and fracture of maxillary right central incisor involving enamel and dentine in a 9-year- old girl is presented. The dental occlusion was deranged due to the luxation. Management consisted of repositioning of the luxated toot...

MANY APPROACHES FOR CROWDED MANDIBULAR ANTERIOR TEETH ARE CURRENTLY EMPLOYED: distal movement of posterior teeth, lateral movement of canines, labial movement of incisors, interproximal enamel reduction, removal of premolars, removal of one or two incisors, and various combinations of the above. Selecting the best treatment is often difficult, and all guidelines do not apply to every case. Trea...

AIM To describe the successful non-surgical endodontic management of a permanent maxillary lateral incisor tooth with four root canals. SUMMARY Aberrant morphology of root canals can occur in any tooth, including maxillary lateral incisors. In the presented case, clinical examination and radiographs clearly depicted the presence of four root canals in a right maxillary lateral incisor. The di...

Anomaly in the number of teeth may manifest as a supernumerary tooth. Occurrence of a supernumerary tooth in the mandibular incisor region is uncommon. This report presents a rare case of five mandibular permanent incisors in a nine year old non-syndrome healthy male child. Clinical and radiographic examination revealed the presence of a supplemental (type of supernumerary) permanent incisor in...

Fusion of teeth is the union of two or more tooth germs, which are usually separated. Depending upon the stage of odontogenesis, it can be complete or incomplete. The present case describes fusion between the maxillary primary right central and lateral incisor with a supernumerary tooth. Clinical and radiographic examination revealed the presence of fused triple teeth. The fused teeth were extr...
