Common variants of EDA are associated with non-syndromic hypodontia.

Objective: The aim of this case-control study was to investigate the association between non-syndromic hypodontia and nineteen common variants of candidate genes ectodysplasin A (EDA), paired box 9 (PAX9), msh homeobox 1 (MSX1) and axis inhibition protein 2 (AXIN2).

Settings And Sample Population: Sixty-one hypodontia cases were frequency-matched to 253 controls with no missing teeth (excluding the third molars).

Material And Methods: Self-report data and DNA samples were collected from each participant.

Bone fill following secondary alveolar bone grafting for children with cleft of the alveolus in New Zealand.

Objective: To investigate the amount of bone fill post-secondary alveolar bone grafting for children with cleft in New Zealand.

Settings And Sample Population: Retrospective analysis of post-operative intra-oral periapical and upper anterior occlusal radiographs of 45 grafted sites where all grafting was undertaken within the New Zealand public hospital service.

Materials And Methods: A modified Kindelan Index and a 100 mm visual analogue scale (VAS) were used to assess the amount of bone fill using intra-oral radiographs by 4 orthodontists experienced in cleft care and who were blind to the patient's identity.

Long-term changes in oral health-related quality of life of standard, cleft, and surgery patients after orthodontic treatment: A longitudinal study.

Introduction: The aim of this study was to assess long-term changes and describe the trajectories of oral health-related quality of life (OHRQoL) in a cohort of cleft, surgery, and standard patients who received orthodontic treatment.

Methods: Standard (n = 16), cleft (n = 19), and orthognathic surgery (n = 22) patients completed the short-form of the Oral Health Impact Profile (OHIP-14) before treatment, immediately posttreatment, and approximately 5 years posttreatment.

Results: An overall reduction in OHIP-14 scores (improvement in OHRQoL) occurred after orthodontic treatment; however, this was only significant for the surgery and standard groups (P <0.

Comparison of Reliability of Categorical and Continuous Scales for Radiographic Assessments of Bone Infill Following Secondary Alveolar Bone Grafting.

Objectives: To investigate examiner reliability of scoring intraoral radiographs of bone infill following secondary bone grafting using a categorical scale (modified Kindelan Index) and a 10-cm visual analog scale (VAS). To investigate the level of clinical experience on the reliability of these assessments.

Design: Retrospective study involving 10 clinicians of varying clinical experience who were blind to the patient's identity.

Hypodontia: An Update on Its Etiology, Classification, and Clinical Management.

Hypodontia, or tooth agenesis, is the most prevalent craniofacial malformation in humans. It may occur as part of a recognised genetic syndrome or as a nonsyndromic isolated trait. Excluding third molars, the reported prevalence of hypodontia ranges from 1.

Management of missing mandibular second premolars: a review.

Tooth agenesis is the most common developmental dental anomaly and it is frequently associated with other dento-skeletal disturbances, such as structural variations of other teeth, late dental eruption, transpositions and crowding. Except for the third molars, the mandibular second premolars are the most commonly missing teeth. Oral rehabilitation of patients with missing mandibular premolars often requires a multi-disciplinary approach, and usually results in prolonged treatment time and a greater burden of care.

An osteosclerotic form of Robinow syndrome.

Robinow syndrome (RS) is a clinically and genetically heterogenous condition primarily characterized by short stature, mesomelia, genital hypoplasia, oral abnormalities, and a facial gestalt that includes hypertelorism, a short nose, and a broad mouth. The disorder exists in both a dominant and a more severe recessive form. Here two unrelated cases of sporadic RS are described with the additional finding of axial and appendicular osteosclerosis.

New Zealand dentists' use of gingival retraction techniques for fixed prosthodontics and implants.

Objective: To identify the techniques most commonly used in New Zealand for gingival retraction for impressions of natural teeth and implants in fixed prosthodontics.

Design: Postal survey of a random sample of dentists

Methods: A questionnaire was mailed to all members of the New Zealand Dental Association (NZDA). Data were analysed using SPSS.
