Talon cusp is an odontogenic anomaly in anterior teeth, caused by hyperactivity of enamel in morphodifferentiation stage. Talon cusp is an additional cusp with several types based on its extension and shape. It has enamel, dentin, and sometimes pulp tissue. Moreover, it can cause clinical problems such as poor aesthetic, dental caries, attrition, occlusal interferences, and periodontal di...

OBJECTIVE The purpose is to compare temperature rise in the pulp chamber during fabrication of provisional crowns using different materials and on different types of teeth using direct technique. MATERIALS AND METHODS An extracted, sound, caries free maxillary central incisor and a mandibular molar were selected for the study and crown preparations of all ceramic and all metal were done on ce...
The aim of this study was to re-examine Leon Williams geometric theory and to find the degree of correspondence between the face and the tooth form in the population of Zenica, Bosnia and Herzegovina. Two thousand individuals with intact frontal teeth, in age between 17 and 24 years, were measured for 3 horizontal distances on the face: temporal width (Ft-Ft), zygomatic width (Zyg-Zyg) and goni...
