Self-harm, dentofacial features, and bullying.

Introduction: Self-harm is a growing public health problem. The study aimed to investigate the prevalence of self-harm among a representative sample of school children and the contribution of dentofacial appearance and being bullied because of dentofacial appearance to self-harm.

Methods: This was a cross-sectional study in which a representative sample of eighth-grade students (aged 13-14 years) from randomly selected schools was asked to complete anonymous questionnaires distributed in the classroom.

Do various degrees of tooth decalcification affect orthodontists', general dentists' and laypersons' ratings of smile esthetics?

Objectives: To compare the effect of various degrees of decalcification after orthodontic treatment (white spot lesions) on orthodontists', general dentists', and laypersons' ratings of smile esthetics.

Materials And Methods: Eight photographs representing incrementally altered tooth decalcification lesions of maxillary anterior teeth ranging from mild to severe were shown randomly to the study participants. Photographs were rated by a matched sample of orthodontists (N = 42), general dentists (N = 52), and laypeople (N = 58).

Impact of bullying due to dentofacial features on oral health-related quality of life.

Introduction: The aim of this study was to investigate whether there is a relationship between self-reported bullying because of dentofacial features and oral health-related quality of life among a representative sample of Jordanian schoolchildren.

Methods: This was a cross-sectional study in which a representative sample of sixth-grade students (age, 11-12 years) from randomly selected schools in Amman, Jordan, were asked to complete questionnaires distributed in the classroom in the presence of the researchers. The questionnaire used for this purpose was the short form of the Child Perceptions Questionnaire for 11- to 14-year-old children.

Bullying among Jordanian schoolchildren, its effects on school performance, and the contribution of general physical and dentofacial features.

Introduction: The aims of this study were to investigate the experience of bullying in a representative sample of Jordanian schoolchildren in Amman, to look at its effect on school attendance and perception of academic performance, and to look at the contribution of general physical and dentofacial features to this phenomenon.

Methods: This was a cross-sectional study in which a representative sample of sixth-grade students (11-12 years of age) from randomly selected schools was asked to complete questionnaires distributed in the classroom in the presence of the researchers. The final sample size was 920 children (470 girls, 450 boys).

A comparison between a new 2-dimensional digital on-screen tooth measurement method with direct measurements.

Objective: To compare the accuracy and reproducibility of tooth measurements using newly developed software that gives 2-dimensional scanned images of dental setups with direct measurements using digital calipers.

Methods: This experimental study was performed at the Dental Laboratories of the Faculty of Dentistry, University of Jordan, Amman, Jordan from September 2010 to December 2010. Ten sets of acrylic teeth (10 upper and 10 lower arches) were used.

Effect of gender on performance of undergraduate dental students at the University of Jordan, Amman.

The purpose of this study was to see if gender-based differences exist in the performance of dental students at the University of Jordan (UJ), Amman. The retrospective analysis included data from two groups of students: 413 fourth-year dental students (178 males and 275 females) from four consecutive years (2005 through 2008) and 357 fifth-year students (128 males and 229 females) who graduated in the years 2005 to 2008. The influence of gender on the results of the fourth-year students in six theoretical and six clinical courses and the cumulative GPAs of the fifth-year students were studied.

Condition-specific quality of life in Jordanian patients with dentofacial deformities: a comparison of generic and disease-specific measures.

Objectives: To determine the impact of dentofacial deformities and related treatment on quality of life (QOL) of Jordanian patients, and to make a comparison between the generic and specific measures used.

Study Design: A case-control study was performed involving 143 subjects: 36 before surgery, 35 after orthognathic treatment, 35 who declined surgery (Dec-surg), and 37 control subjects. Their QOL was assessed using the 36-item Short-Form Health Survey (SF-36) and Orthognathic Quality of Life Questionnaire (OQLQ).

Factors affecting satisfaction of patients after orthognathic surgery at a University Hospital.

Objective: To analyze factors that influence patient's satisfaction with orthognathic treatment and evaluate patient's perception of changes in physical and psychosocial aspects.

Methods: In a retrospective clinical study conducted at Jordan University Hospital, Amman, Jordan between December 2006 and December 2007, we examined 38 patients who had orthognathic surgery after an average follow-up of 20 months. Examination included evaluation of nerve function and temporomandibular function with Helkimo index.

Tooth size discrepancies among Jordanian schoolchildren.

The aims of this study were to determine the tooth size discrepancies (TSD) in a representative sample of Jordanian schoolchildren and to compare TSD between genders. Dental casts of 367 (174 males and 193 females; mean age 15.5 years) Jordanian schoolchildren were selected.

Mixed dentition analysis in a Jordanian population.

Objective: To examine the applicability of the Tanaka and Johnston method of prediction in a Jordanian population and to develop a new prediction method for this specific population if necessary.

Materials And Methods: Three-hundred and sixty-seven Jordanians (193 female, 174 male, mean age 15.5 years) were randomly selected to represent 0.

Application of Pont's Index to a Jordanian population.

The aim of this study was to assess the applicability of Pont's Index to a Jordanian population and to compare the results with those obtained from studies of different ethnic subjects. Dental casts of 144 Jordanians (71 males and 73 females; mean age, 15.5 years) with 'normal' occlusions were selected from the records of a random stratified sample of 383 Jordanian schoolchildren in the 10th grade.

Ranking dental aesthetics and thresholds of treatment need: a comparison between patients, parents, and dentists.

The aims of the present study were to compare rankings of dental aesthetics and the threshold at which orthodontic treatment would be sought among patients, parents, and dentists. A prospective cross-sectional study was designed to address these aims. The study sample comprised 100 patients and parents and 23 dental specialists.

Regional odontodysplasia: a review of the literature and report of a case.

We present a rare case of a developmental anomaly called regional odontodysplasia or 'ghost teeth' in an 8.5-year-old Jordanian girl. The anomaly affected both the mandibular primary and permanent incisors, and the canines bilaterally.
