AIM The aim of this study was to investigate the cementoenamel junction of a group of 11 primary sound mandibular incisors extracted for orthodontic reasons. MATERIALS AND METHODS Eleven caries and defect-free human inferior deciduous incisors were extracted for orthodontic reasons and the cementoenamel junction was investigated by scanning electron microscopy (SEM). The types of tissue inter...

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...

Megaraptorid theropods were an enigmatic group of medium-sized predatory dinosaurs, infamous for the hypertrophied claw on the first manual digit. Megaraptorid dentition is largely restricted to isolated teeth found in association with skeletal parts; however, the in situ maxillary dentition of Megaraptor was recently described. A newly discovered right dentary pertaining to the Australovenator...

Background and Aim : The objective of this study was to evaluate the prevalence of non–syndromic supernumerary teeth, to classify them, to identify the related complications, and to determine the type of the treatment for them. Subjects and Methods : This retrospective study used 7753 panoramic radiographs of patients who presented themselves at Oral and Maxillofacial Surgery Department from Ja...

Clinicians frequently encounter hypodontia in their practice. It can be associated with any syndrome or more commonly it is asyndromic. This asyndromic form is commonly familial and can be followed in heredity of the patient. The patient referred in this report presented with a rare anomaly of hypodontia with altered morphology where the patient had all the teeth single rooted and single canall...

Objective: To evaluate root canal configuration and morphology of premolar teeth among Saudi subpopulations using cone beam computed tomography (CBCT). Material Methods: In this retrospective cross-sectional study, CBCT images 314 patients comprising 346 maxillary 412 mandibular first (FPM) teeth, 298 387 second (SPM) were analyzed to the number roots, morphology, based on Vertucci's classifica...

Supernumerary teeth or hyperdontia are defined as the teeth that exceeds the normal dental formula, regardless of their location and morphology. A supernumerary tooth is a developmental anomaly and it has been argued to arise from multiple aetiologies. Supernumerary teeth with orthodox shapes and sizes, that resemble the normal dentition are called 'supplemental teeth'. The supplemental teeth a...

The overall aim of this thesis was to study dentofacial morphology in Turner syndrome (TS) versus controls and the influence hereupon from karyotype. One hundred thirty two TS females (5-66 years of age), from Göteborg, Uppsala and Umeå were participating. Cephalometric analysis, cast model analysis concerning palatal height, dental arch morphology and dental crown width were performed. Eightee...
