In a recent paper Schwartz ('74) proposes revised homologies of the deciduous and permanent teeth in living lemuriform primates of the family Indriidae. However, new evidence provided by the deciduous dentition of Avahi suggests that the traditional interpretations are correct, specifically: (1) the lateral teeth in the dental scraper of Indriidae are homologous with the incisors of Lemuriadae ...

Introduction: Papillon­Lefevre Syndrome (PLS) is a rare autosomal recessive disorder of keratinisation, characterized by palmoplantar hyperkeratosis, periodontitis and early loss of dentition. Since these features are common to both dentistry and dermatology, members of both disciplines should be aware of the same because an early diagnosis of this condition can help to preserve the teeth by ea...

Mesiodistal and buccolingual crown dimensions of the right deciduous teeth of 133 white children were analyzed for information on sexual dimorphism and sex discrimination using discriminant analysis. Even though consistent differences were found for only 15 out of 20 paired measurements, five of them significant a t p = 0.05 or better, discriminant analysis showed the possibility of correctly s...

OBJECTIVE The establishment and maintenance of normal occlusion constitutes one of the important objectives of pediatric dentistry. There are very few studies assessing the occlusal characteristics of primary dentition in the preschool children. The objective of this study was to assess the occlusal characteristics of primary dentition and difference in various parameters, in children between 3...

A characteristic feature of mammalian dentition is the evolutionary reduction of tooth number and replacement. Because mice do not replace teeth, here we used Sorex araneus, the common shrew, as a model to investigate the loss of tooth replacement. Historically, shrews have been reported to initiate the development of several, milk or deciduous teeth but these soon become rudimentary and only t...

OBJECTIVE The objective of this study is to investigate the eruption pattern and root resorption of the bovine anterior dentition in relation to growth-related parameters based on dental maturity. METHODS A cross-sectional study was conducted on 110 bovine anterior mandibles by using standard radiography, cone-beam computed tomography (CBCT), and actual measurements. We determined the relatio...

dental anomalies are rare findings that may affect development of occlusion and early intervention may be required. here, a case of multiple anomalies in primary and perma nent dentitions is reported. the patient referred to the dental center with the chief complaint of multiple tooth decay. in the oral examination, the rare case of triplica tion between the right geminated man-dibular a and ri...

Objective To estimate the risk of PDC occurrence in children with dental anomalies identified early during mixed dentition. Material and Methods The sample comprised 730 longitudinal orthodontic records from children (448 females and 282 males) with an initial mean age of 8.3 years (SD=1.36). The dental anomaly group (DA) included 263 records of patients with at least one dental anomaly ident...

Perianesthetic dental trauma is not uncommon with an incidence as low as 0.02%-0.07% up to 12.1% of cases of the general anesthesia (GA) 1. Incidence of overall oral trauma is reported as high as 7% of individuals who underwent GA 2. Indeed, emergency endotracheal intubation and less experienced staff probably increase the chance of traumatizing hard and soft oral tissues 3. The majority of inc...

The prevalence, possible etiological factors and management of multiple missing primary teeth was briefly reviewed. Oligodontia of the primary dentition is a rare finding. This paper reports a rare case of multiple missing (n=9) primary teeth in a 3-year-old male of Asian origin.
