Dens evaginatus is a developmental anomaly that is observed as additional tuberculate cusp on the palatal surface of incisor teeth (talon cusp) or the occlusal surface of molar teeth. This additional cusp consists of enamel, dentin, and usually pulp. A 9-year-old boy presented with a talon cusp on the palatal surface of maxillary left lateral incisor. The clinical and radiographic appearance an...

INTRODUCTION Panoramic imaging is a technique for producing a tomographic image of the facial structures, maxillary, mandibular dental arches and their supporting structures [1]. The primary advantage of panoramic imaging is the broad coverage of the facial bones and teeth and the most common demerit is that of the resolution. Image interpretation in an OPG demands a systematic approach and a t...

dens invaginatus is a rare developmental anomaly of teeth with complex root canal system morphology. the present case describes a peg shape maxillary lateral incisor with dens invaginatus (oehlers type ii), necrotic pulp, and an associated large periradicular lesion. nonsurgical endodontic treatment was performed with the aim of removing the blind sac with diamond bur under the use of operating...

A case of a compound odontoma which caused delayed eruption of right maxillary central incisor in a ten year old girl is presented with clinical and radiographic findings. The patient presented with complaint of a hard painless swelling in the right anterior region of the maxilla and absence of right maxillary central incisor. After clinical examination, periapical and occlusal radiographs of t...

eral incisors. EW springs were then bonded to anchor-wire segments as described above (Fig. 3). Three months later, the upper lateral incisors had been significantly intruded (Fig. 4). After the intrusion auxiliaries were removed, a bracket was bonded to the left lateral incisor for incorporation into the main archwire; an .008" ligature wire was bonded to the surface of the right lateral incis...

A series of 6-aryl-5-cyano-2-thiouracil derivatives (1a-d) was synthesized by the reaction of ethyl cyanoacetate with thiourea and aldehydes. These products were used as intermediate compounds for the synthesis of a number of thiouracil derivatives (2a-d to 10a-d). All compounds were screened for antibacterial and antifungal activities. Some of the prepared compounds, 6-(4-fluorophenyl)-4-oxo-2...

Vertical loads and root surface strains in extracted teeth during lateral condensation using finger and hand spreaders were measured and compared with loads and strains at fracture. Six groups each of 10 teeth were tested: maxillary central incisor, premolar and molar; and mandibular incisor, premolar and molar. Root strains were measured using strain gauges mounted on the apical and middle thi...

BACKGROUND Dental anomalies associated with different severities of cleft lip and palate have been rarely reported. This retrospective study investigates the characteristics of dental anomalies associated with different types of cleft, and compares the dental anomaly traits based on sex and severity of cleft. METHODS Cleft patients born in 1995 with qualified diagnostic records from 7 to 11 y...

INTRODUCTION Our aim was to comparatively investigate the amount of external apical root resorption (EARR) between conventional and passive self-ligating brackets. METHODS Ninety-six patients were selected from a pool of patients satisfying the following inclusion criteria: no evidence of resorption on the pretreatment panoramic radiographs; no contributing history of trauma; no dilacerations...
