When a tooth shows discoloration and does not respond to the cold test or electric pulp test (EPT) after a traumatic injury, its diagnosis can be even more difficult due to the lack of proper diagnostic methods to evaluate its vitality. In these case reports, we hope to demonstrate that ultrasound Doppler might be successfully used to evaluate the vitality of the tooth after trauma, and help re...

PURPOSE The objective of this study was to assess the outcomes for treated root-fractured permanent incisors with respect to pulp vitality, root tissue union, and tooth survival and to examine the effects of clinical and radiographic parameters and rigid splinting on the outcome. METHODS Eighty-four teeth were identified and data extracted from case notes prior to transfer to an SPSS data bas...

The indications for impacted third molar extraction include the prevention of dental reabsorption on the adjacent tooth. Resorption can be classifi ed as physiological (when deciduous teeth are exfoliated) or pathological (when caused by injury or irritation to the periodontal ligament). Many causes can trigger external root resorption (ERR), the most common cause of which is orthodontic forces...

A study of the degree and gradient of attrition was undertaken on 352 molar teeth of 88 selected Nigerian subjects. A method for the quantification of attrition experience per molar tooth is described. There is a close correlation between age and the degree of attrition of the first molar. This finding may be of value in age determination in forensic odontology. The wear on the first molar is a...

Retention, that is, a permanent tooth which is unerupted more than a year after the normal age of eruption, is a relatively rare event, except in the case of the third molars and the upper canines. Transmigration is defined as the phenomenon of more than half an unerupted impacted tooth crossing the midline. We report the clinical case of a twenty-year-old patient presenting transmigration of t...
