Implementation of a Medical Ethics Course in Undergraduate Dental Education and Assessment of Knowledge and Attitudes.

OBJECTIVES: A medical ethics course was launched in 2012 in a French University Dental School. We compared knowledge and attitudes, before and after implementation of that course. The aim of this study was to compare students who received an ethics course (third year) to those who did not have such training, however, most of them did have some clinical traineeship. MATERIALS AND METHODS: An anonymous questionnaire was sent to the second-, third-, and sixth-year students. It comprised questions with Likert item format answers and clinical vignettes with open responses. The results were analyzed by two approaches: a statistical analysis (chi-square or Fischer exact tests) and a content analysis using a predefined grid. RESULTS: A total of 299 respondents replied (75% students) the questionnaire. The analysis showed a statistically significant association between knowledge of the law and information procedures (P < 0.0001), access to medical files (P = 0.004), and recording consent (P = 0.049). It was also significant between knowledge of the law and the principles of biomedical ethics (P < 0.0001 for autonomy and beneficence). The third-year students could state the principles of medical ethics with their percentage always greater than the sixth-year students. After the third year, the students' attitudes switched from a social to a medical emphasis, and their point of view regarding patient's autonomy evolved. Patient's refusal of care raised potential conflicts between autonomy, professional judgment, information, and consent. CONCLUSION: Ethics teaching could offer a way to turn positive attitudes into real competencies and should be considered at an early stage.

Dental complications of rickets in early childhood: case report on 2 young girls.

Vitamin D is an essential hormone for calcium gut absorption. It is also involved in child growth, cancer prevention, immune system responses, and tooth formation. Due to inadequate vitamin D intake and/or decreased sunlight exposure, vitamin D deficiency has resurfaced in developed countries despite known inexpensive and effective preventive methods. Vitamin D deficiency is a common cause of rickets, a condition that affects bone development in children and that can have serious dental complications. Deficiency during pregnancy can cause enamel hypoplasia of primary teeth. Enamel regeneration is currently impossible; hypoplasia is therefore irreversible, and once affected, teeth are prone to fast caries development. Deficiency during early childhood can affect permanent teeth and ensuing caries can sometimes lead to tooth loss at a young age. Oral manifestations of rickets should be diagnosed early by both physicians and dentists to prevent severe dental complications. This case study presents 2 young girls with rickets in early childhood who suffered from subsequent serious tooth decay.

Sedation with 50% nitrous oxide/oxygen for outpatient dental treatment in individuals with intellectual disability.

Persons with intellectual disability have difficulty in cooperating with outpatient care, and many are referred for general anaesthesia. Intellectual disability has traditionally been a contraindication for conscious sedation. We evaluated the behavioural impact, effectiveness, and tolerance of sedation in this population using a fixed 50% nitrous oxide/oxygen mixture as a single agent. We used dental treatment as a model of outpatient care; 349 patients (192 males, 157 females; mean age 22y [SD 14]; range 3-81y) were recruited over a 12-month period at seven centres. Sedation was deemed successful if planned dental treatment was completed. Behaviour was scored with the modified Venham scale. Out of 605 sessions, 91.4% were successful. No serious adverse effects occurred. Minor adverse events (such as nausea) occurred in 10.1% of sessions. We conclude that the use of safe and effective conscious sedation may reduce the indications for general anaesthesia.

Caries experience in the primary dentition among French 6-year-olds between 1991 and 2000.

BACKGROUND: There are few national caries preventive policies for children in France. Various surveys suggest that in the late 1980s, oral health of the 6-year olds in France was poorer than in those of other European countries. In Val de Marne (a Department just east of Paris) a public dental service was established in 1991. A programme to inform preschool staff about dental diseases was commenced and volunteers brought oral health information to parents and health professionals. Periodical monitoring of primary tooth caries of 6-year olds was planned. AIM: The aim of the study was to evaluate changes in primary tooth caries in 6-year olds over the 10 years of the programme. METHODS: Participating 6-year olds, randomly selected, were examined in schools by dentists. Clinical data were collected (WHO criteria). Sociodemographic data were collected through questionnaire. Statistical analysis involved comparison of mean values, variance analysis and chi-square test for categorical variables. RESULTS: The proportions of children with caries experience were, 38.9%, 30.6% and 22.2% in 1991, 1995 and 2000 respectively (P < 0.01). The dft index decreased from 1.74 to 1.39 and 1.05 respectively. About 75% of children with dental caries remained untreated. Children of non-European native parents or belonging to low socioeconomic families remained those most affected by dental caries in 2000. CONCLUSION: Dental caries in 6-year olds improved between 1991 and 2000 in Val de Marne but caries remained a socially inequitable disease. Most children did not have access to dental care. The situation requires changes to the dental care provision system.

Dental abnormalities in patients with familial hypophosphatemic vitamin D-resistant rickets: prevention by early treatment with 1-hydroxyvitamin D.

OBJECTIVE: To evaluate the dental effects of 1-hydroxylated vitamin D3 treatment in patients with familial hypophosphatemic vitamin D-resistant rickets. Study design Forty-eight children and adult patients were included in the study; 16 had received no treatment or phosphate supplements with vitamin D/25-(OH) D3 before puberty. The 32 younger ones had received phosphate supplements with 1alpha-(OH)D3 from infancy. All patients were clinically examined, and panoramic and periapical radiographs were made. Evaluations of decayed, missing, or filled teeth and decayed or filled teeth indexes and of pulp ratios allowed comparison with healthy age-matched control patients. RESULTS: Poor dental health and characteristic dental anomalies were found in the 16 older patients. In contrast, the 32 younger patients had a normal dental status as regards reference ranges in healthy age-matched populations, although they still showed prominent pulp horns on deciduous teeth and increased pulp area/tooth area ratios. CONCLUSIONS: This investigation shows the beneficial effects of 1alpha-(OH)D3 treatment on the dental status of vitamin D-resistant rickets patients and emphasizes the necessity of early treatment. Remaining defects may result from early exposure of odontoblasts and surrounding osteoblasts to hypophosphatemia, before the commencement of treatment, and/or from intrinsic cell disturbances linked to the genetic alteration(s).
