PURPOSE The aim of this retrospective study was to investigate the possible association between peri-implant marginal bone loss and the apicocoronal (vertical) positioning of dental implants placed adjacent to a tooth. MATERIALS AND METHODS Dental records at the University of Michigan, School of Dentistry, were screened. To be included in the study, the patient had to have at least one implan...

The purpose of this study was to study the stability of teeth adjacent to posterior edentulous spaces and correlate it with patient age and time lapse since tooth loss. Dental casts, panoramic radiographs, and questionnaires of patients treated in a University setting were employed. Teeth adjacent and opposing posterior edentulous spaces were examined for the following parameters: Supraeruption...

A Dentigerous Cyst (DC) is the most common developmental odontogenic cyst that mostly happens in patients between 10 to 30 years of age. It is usually completely asymptomatic and is discovered on a routine radiographic examination or to evaluate the reason for an erupted tooth. Radiographically, this cyst usually presents a well-defined unilocular radiolucency attached to CEJ of an unerupted to...

The development of alveolar bone adjacent to the tooth root during tooth eruption is not well understood. This study tested the hypothesis that predominantly woven bone forms adjacent to tooth roots during tooth eruption, but that this immature structure transitions to lamellar bone when the tooth comes into function. Additionally, bone resorption was predicted to play a key role in transitioni...

In order to clarify the peripheral mechanisms of ectopic persistent pain in a tooth pulp following pulpal inflammation of an adjacent tooth, masseter muscle activity, phosphorylated extracellular signal-regulated protein kinase (pERK) and TRPV1 immunohistochemistries and satellite cell activation using glial fibrillary acidic protein (GFAP) immunohistochemistry in the trigeminal ganglion (TG) w...

An increased number of teeth in relation to normal dental formula is called hyperdontia, and the additional tooth are termed as supernumerary tooth. A supplemental a that closely resembles shape its adjacent with which they associated supplements for occlusion. Primary dentition presents lower prevalence compared permanent dentition.

This article will discuss and evaluate the potential conditions that can present in patients who require or already have had multiple anterior tooth extractions; the proper considerations for the use of ovate pontics in the treatment plan also will be discussed. While the ultimate treatment decisions must be determined on a case-by-case basis, it is important to recognize in advance the various...
