Co-occurring species might be morphologically similar because they are adapted to the same environment, or morphologically dissimilar to minimize competition. We use sister species comparisons to evaluate the relationship between morphological disparity and regional patterns of co-occurrence across carnivores. Up to 63% of the variation in range overlap can be explained by morphological diverge...

OBJECTIVE The purpose of the modified repositioning appliance was to overcome the shortcoming of existing design for repositioning protruded premaxilla in a child with bilateral cleft lip and palate. METHODS The basic principles of design were similar to Latham's appliance but the surgical pinning of premaxillary segment was avoided and instead acrylic splint was prepared. CONCLUSIONS This ...

It is often very difficult to replant avulsed teeth in the deciduous and mixed dentition when the cortical bone is fractured and there are no adjacent teeth for anchorage. In this article, we describe the management of avulsed maxillary incisors in a 7-year-old boy. The avulsed teeth could be successfully repositioned by intra-alveolar transplantation using the 180° rotation (buccolingual rever...

Dental caries in the primary dentition can have significant damaging effects on a childs growth due to impairment of oral functions. Since the first encounter of a child to a medical environment is often through pediatricians and medical practitioners, it is important that they be aware of the prevention of oral disease that begins early in life. The aim of this article is to diminish the exist...

Idiopathic hypoparathyroidism (IHP) is a rare endocrinopathy, characterized by the disturbances in calcium and phosphorous metabolism, owing to deficiency in parathyroid hormone, which leads to tetanic manifestations. Onset of the clinical features occurs early in life, and the severity depends on the extent of chemical imbalance. This article describes a case of 22-year-old patient undiagnosed...

Radicular cysts are considered rare in the primary dentition, comprising only 0.5 to 3.3% of the total number of radicular cysts in both primary and permanent dentitions. The aim of this case report is to present the clinical, radiographic and histological characteristics of radicular cyst associated with primary central incisor. Extraction and enucleation of the cyst was carried out under loca...

Dens evaginatus (DE) is a rare developmental anomaly characterized by presence of an extra cusp arising from occlusal or lingual surfaces. Isolated occurrence or concomitant presence of DE with other dental anomalies has been reported. DE commonly affects permanent teeth and is rarely seen in primary dentition. Treatment may be conservative or radical. This article presents two unusual cases of...

Dental disease and its prevention and treatment comprises approximately 10% of the general equine practitioner’s work. The most common disease affecting the equine hypsodont teeth is the development of dental overgrowths. Brachydont dentition (canines and wolf teeth) are less often diagnosed with dental disease. Gingivitis and periodontal disease as seen in many young horses can affect any toot...

Papillon-Lefèvre syndrome (PLS) is a rare autosomal recessive disorder, characterized by diffuse palmoplantar keratoderma and precocious aggressive periodontitis, leading to premature loss of deciduous and permanent dentition at a very young age. Various etiopathogenic factors are associated with the syndrome, like immunologic alterations, genetic mutations, and the role of bacteria. Dentists p...
