Interventions for promoting the eruption of palatally displaced permanent canine teeth, without the need for surgical exposure, in children aged 9 to 14 years.

Background: A permanent upper (maxillary) canine tooth that grows into the roof of the mouth and frequently does not appear (erupt) is called a palatally displaced canine (PDC). The reported prevalence of PDC in the population varies between 1% and 3%. Management of the unerupted PDC can be lengthy, involving surgery to uncover the tooth and prolonged orthodontic (brace) treatment to straighten it; therefore, various procedures have been suggested to encourage a PDC to erupt without the need for surgical intervention.

WITHDRAWN: Extraction of primary (baby) teeth for unerupted palatally displaced permanent canine teeth in children.

Background: The permanent canine tooth in the maxillary (upper) jaw sometimes does not erupt into the mouth correctly. In about 1% to 3% of the population these teeth will be diverted into the roof of the mouth (palatally). It has been suggested that if the primary canine is removed at the right time this palatal eruption might be avoided.

Open versus closed surgical exposure of canine teeth that are displaced in the roof of the mouth.

Background: Palatally displaced canines or PDCs are upper permanent canines, commonly known as 'eye' teeth, that are displaced in the roof of the mouth. This can leave unsightly gaps, cause damage to the surrounding roots (which can be so severe that neighbouring teeth are lost or have to be removed) and, occasionally, result in the development of cysts. PDCs are a frequent dental anomaly, present in 2% to 3% of young people.

Orthodontic Camouflage Treatment of Class II Division I Malocclusion in a Patient with Myotonic Dystropy.

Case report of a patient with Class II division I malocclusion, increased overjet and reduced overbite treated with combination of functional and fixed appliance is presented. Medically she suffered from myotonic dystrophy. Rationale for the treatment plan and effect of myotonic dystrophy on treatment outcome are discussed.

Bond failure of gingivally offset mandibular premolar brackets: a randomized controlled clinical trial.

Introduction: The purpose of this randomized controlled clinical trial was to examine the clinical bond failure rate of gingivally offset mandibular premolar brackets and compare it with that of standard mandibular premolar brackets.

Methods: Eighty-three patients were enrolled in this trial. A total of 240 brackets--120 standard and 120 offset--were bonded in a split-mouth design.

Open versus closed surgical exposure of canine teeth that are displaced in the roof of the mouth.

Background: Palatal canines are upper permanent canine (eye) teeth that have become displaced in the roof of the mouth. They are a frequently occurring anomaly, present in 2% to 3% of the population. Management of this problem is both time consuming and expensive and involves surgical exposure (uncovering) followed by fixed braces for 2 to 3 years to bring the canine into alignment within the dental arch.

A comparison of tungsten-quartz-halogen, plasma arc and light-emitting diode light sources for the polymerization of an orthodontic adhesive.

This study investigated whether there were differences between the debond stress and adhesive remnant index (ARI) of an adhesive cured with three different orthodontic light sources. Sixty sound premolar teeth were divided into three groups of 20. A standard pre-adjusted edgewise premolar bracket (Victory Series) was bonded to each tooth using a light-cured orthodontic adhesive, Transbond X.

Management of hypodontia: restorative considerations. Part III.

This paper, the third in the series, initially details the role of the restorative dentist in treating patients with hypodontia. (See Quintessence Int 2005;36:263-270 and 345-353 for the first two papers.) A range of treatment options, including implants, adhesive techniques, and removable prostheses, are covered.

Management of hypodontia: orthodontic considerations (II).

Patients with congenitally missing teeth (hypodontia) present with complex problems. Meeting their treatment needs requires a joint effort between the disciplines of orthodontics and restorative dentistry. There are a number of options available to restore space generated by missing teeth.

Hypodontia--a retrospective review of prevalence and etiology. Part I.

A retrospective literature review was carried out to determine the prevalence of hypodontia and current knowledge of associated etiological factors. Reported studies vary widely in their reports of prevalence. The majority are retrospective radiographic studies, and reported rates vary from 2.
