One hundred adult South African Negro skulls having a complete maxillary dentition were examined for the pre­ sence of dehiscence and fenestrations o f the labial or buccal alveolar plate. The defects were diagnosed ac­ cording to the definition in the Journal o f Periodontology, Glossary.of Terms (1977). It was found that 8,4 per cent o f teeth had either dehiscences or fenestrations and 28,5 ...

The orthodontic treatment of an adult patient with a skeletal Class III malocclusion, increased anterior facial height, negative overjet, and bilateral posterior crossbite is presented. Treatment options included mandibular first premolar or third molar extractions with dentoalveolar compensation or combined surgical-orthodontic treatment. Mandibular third molar extraction with dentoalveolar co...

BACKGROUND The objective of this retrospective case-control study was to measure the maxillary lateral incisor root dimensions and quantify the labial and palatal bone in patients with unilateral maxillary lateral incisor agenesis (MLIA) after orthodontic treatment and compare them to non-agenesis controls using cone beam computed tomography. METHODS The labiopalatal and mesiodistal root dime...

OBJECTIVE To examine the ultimate accuracy of bracket placement in labial vs lingual systems and in direct vs indirect bonding techniques. MATERIALS AND METHODS Forty pretreatment dental casts of 20 subjects were selected. For each dental cast, four types of bracket placement were compared: labial direct (LbD), labial indirect (LbI), lingual direct (LgD), and lingual indirect (LgI). Direct bo...

We propose PALPS, a Process Algebra with Locations for Population Systems. PALPS allows us to produce spatially-explicit individual-based ecological models and to reason about their behavior. PALPS has two abstraction levels: At the first level, we may define the behavior of an individual of a population and, at the second level, we may specify a system as the collection of individuals of vario...

One hundred and thirty-three second graders in rural public school were assessed on a number of dental, skeletal, and oral muscle function measures. Correlational analyses were conducted in order to determine whether specific myofunctional variables were associated with dentofacial development. Significant relationships were observed between open mouth posture and a narrow maxillary arch and lo...

This report describes a rare palato-radicular groove in a maxillary lateral incisor with an accessory root and an atypical root canal. Failure to identify the presence of the palatal groove allowed infection to persist, which led to palatal swelling and labial fistula. During endodontic retreatment of the infected root canal, an accessory root with a second root canal was detected. Owing to the...
