OBJECTIVE The study tested the hypothesis that case management provided to mentally ill offenders both in jail and after release from jail would reduce their recidivism. METHODS A total of 261 inmates of the Lucas County (Toledo, Ohio) jail who were diagnosed with a mental disorder were tracked for three years after their release. The relationships(More)
OBJECTIVE To assess the activities related to the occurrence of traumatic dental injuries (TDI) in order to establish the relationship between gender, socio-economic status (SES) and major TDI related events, using classification and examination procedures suitable for epidemiological purposes, in a sample of 15- to 18-year-old students in Taiwan. METHODS(More)
Bone morphogenetic proteins (BMPs) are highly conserved signaling molecules that are part of the transforming growth factor (TGF)-beta superfamily, and function in the patterning and morphogenesis of many organs including development of the dentition. The functions of the BMPs are controlled by certain classes of molecules that are recognized as BMP(More)
AIM To examine the nature of dental anxiety in paediatric patients, and to identify factors relevant to paediatric dental anxiety in a sample of 5 to 17 year-old children residing in Cairns, Australia. MATERIALS AND METHODS A convenient sample of 125 children, their parents and corresponding student practitioners were selected. Each was assessed with(More)
OBJECTIVES   This study aimed to investigate dental undergraduate students' tobacco usage and social nicotine dependence in Australia. A special interest was to identify the role of factors such as age, gender, year of dental education and cohabitants' smoking status for social nicotine dependence. MATERIALS AND METHODS   A sample of 252, first-to-fifth(More)
Maxillofacial dysmorphogenesis is found in 5% of the population. To begin to understand the mechanisms required for maxillofacial morphogenesis, we employed the inhibitors of the differentiation 2 (Id2) knock-out mouse model, in which Id proteins, members of the regulator of basic helix-loop-helix (bHLH) transcription factors, modulate cell proliferation,(More)
OBJECTIVES To determine first year dental students' perceptions of intimidation by instructors and bullying by fellow students. METHODS Data were collected through a cross-sectional survey of first year dental students from seven dental schools representing five countries; one each from Romania, South Africa, Australia and the U.S.A., and three from(More)
OBJECTIVE To investigate dental appearance and cephalometric features, using a sample of orthognathic and/or orthodontic patients. A special interest was to identify the relationship of the Dental Aesthetic Index (DAI) with anteroposterior basal bone discrepancy (APBBD) and cephalometric indicators. MATERIALS AND METHODS A full sample of 159 patients in(More)
OBJECTIVES This study aimed to carry out a histological examination of the temporomandibular joint (TMJ) in ank mutant mice and to identify polymorphisms of the human ANKH gene in order to establish the relationship between the type of temporomandibular disorders (TMD) and ANKH polymorphisms. MATERIALS AND METHODS Specimens from the TMJ of ank mutant and(More)
Although runt-related transcription factor 2 (RUNX2) has been considered a determinant of cleidocranial dysplasia (CCD), some CCD patients were free of RUNX2 mutations. CCAAT/enhancer-binding protein beta (Cebpb) is a key factor of Runx2 expression and our previous study has reported two CCD signs including hyperdontia and elongated coronoid process of the(More)
