Translation and validation of the French version of the child perceptions questionnaire for children aged 11 to 14 years old (CPQ11-14) short-form.

Objectives: The COHQoL is a set of questionnaires used to evaluate the impact of oral health on children's quality of life. Although the CPQ8-10 and the P-CPQ have been translated and validated in French, the CPQ11-14 14 has not yet been validated. The aim was to develop a French version of the CPQ11-14 16-items.

Elements of morphology: Standard terminology for the teeth and classifying genetic dental disorders.

Dental anomalies occur frequently in a number of genetic disorders and act as major signs in diagnosing these disorders. We present definitions of the most common dental signs and propose a classification usable as a diagnostic tool by dentists, clinical geneticists, and other health care providers. The definitions are part of the series Elements of Morphology and have been established after careful discussions within an international group of experienced dentists and geneticists.

Translation and cross-cultural validation of the French version of the Sleep-Related Breathing Disorder scale of the Pediatric Sleep Questionnaire.

Background: Sleep-disordered breathing (SDB), including obstructive sleep apnea syndrome, is often underestimated because it requires a burdensome test (ie, polysomnography) to ensure diagnosis. To improve polysomnography referral, it is of utmost importance to validate efficient alternative screening tools. This study aimed to provide a translation and a cross-cultural validation of the Pediatric Sleep Questionnaire (PSQ) into French to obtain an easy-to-use and reliable screening tool.

Parental-Caregivers Perceptions Questionnaire (P-CPQ): translation and evaluation of psychometric properties of the French version of the questionnaire.

Background: The Parental-Caregivers Perceptions Questionnaire (P-CPQ) is a measure of parental/caregivers' perceptions of the impact of children's oral health on quality of life. The aim of the study was evaluate the psychometric properties of the French version of the P-CPQ.

Method: The original P-CPQ was developed in English language and has 31 items divided into four sub-scales.

Translation and validation of the French version of the Child Perceptions Questionnaire for children aged from 8 to 10 years old (CPQ ).

Background: The Child Perceptions Questionnaire (CPQ) belongs to a set of questionnaires measuring Child Oral Health Quality of Life (COHQOL). The CPQ is used to collect the perceptions of children on the impact of oral diseases on their quality of life. This cross-sectional study was aimed to translate the CPQ into French language and evaluate its psychometric properties.

Rare diseases with oral components: care course and quality of life.

Aim: To describe links between the care course of individuals suffering from rare diseases and socio-behavioural risk factors and to ascertain the impact of dental conditions on the quality of life.

Design: A cross-sectional comparative study involving self-reported questionnaire was performed. Care course was evaluated using predisposing, enabling and needs factors.

Caries experience in a severely obese adolescent population.

Aim: The present study assessed caries experience in an adolescent population being treated for severe obesity. The DMFT indices of a group of obese adolescents (n = 41) and a group of nonobese adolescents (n = 41) were compared.

Design: The parameters examined in this transversal study were body mass index (BMI) and the number of decayed, missing, and filled teeth (DMFT).

Orthodontic treatment need in French schoolchildren: an epidemiological study using the Index of Orthodontic Treatment Need.

This survey was undertaken to assess the orthodontic treatment need in a sample of 9- to 12-year-old French children (mean age: 9.77 years; standard deviation: 0.84) attending 12 different schools in the same geographic area of Ile de France.

Evaluation of a dental care program for school beginners in a Paris suburb.

Objectives: Dental care for children is available in France, but the method of administration is cumbersome: care is generally provided by private dentists, and parents can claim reimbursement of at least 70% of the costs afterwards. In the Département of Val d'Oise (north of Paris and including some densely populated suburbs), a scheme is in place to provide 100% reimbursement. To encourage participation, schoolchildren are screened by dentists who advise if treatment is needed.

1.4 Research and the dental student.

There has been significant concern that the dental curriculum and system of clinical education, in particular, is not designed to take advantage of the explosion in knowledge in biomedical science and its application to the health of the public. Although there are some examples of innovations in dental education on a global scale that have the capacity to increase the assimilation of basic and clinical knowledge, most of the dental education models are mired in the traditional '2 + 2' approach to education. This can be seen in North America and the European '2 + 3' model or the stomatological '4 + 2' approach.

Quality of prosthetic care: patients' level of expectation, attitude and satisfaction.

The aim of this study was to compare pre-treatment level of expectation and attitude and post treatment level of satisfaction with different types of prosthetic treatment according to socio-economic and demographic factors. 162 patients attending for a prosthetic rehabilitation completed an initial questionnaire to assess their level of expectation and attitude; after completion of their treatment, a second questionnaire was mailed to evaluate the level of satisfaction. 94 answers were returned (response rate: 62%).

Socio-economic characteristics and personal attitudes of patients attending a French prosthodontic teaching clinic.

The aims of the study were to define the socio-economic characteristics of patients attending a Teaching Hospital Prosthetics Department and to determine the attitudes and aspirations of such patients. The study was performed on 162 patients who requested prosthetic treatment in a French university dental hospital department. They were asked to complete a questionnaire at the beginning of their treatment.

Glycoproteins expression in apical pathologic tissues: clinical incidences.

Indirect immunofluorescence was used for the localization of the primary collagens, fibronectin and laminin. Specimens were extracted from untreated teeth with periapical lesions from patients 20 to 30 years of age. An histological examination enabled the differentiation of granulomas and cysts, and 5 microns sections were used for the indirect immunofluorescence procedure.

Phenotypic characterization of the 3/A/1D-1M osteogenic cell line derived from in vivo transplantation of 3/A/1D-1 chondroprogenitor murine teratocarcinoma cells.

Bone cells involved in the replacement of cartilage by bone in the endochondral ossification process are known to enter via the medullar pathway. A hypothesis for the development of osteoblasts from chondroblasts was investigated by analyzing the phenotypic characteristics of the 3/A/1D-1M cell line derived from endochondral bone ossicle which was formed after in vivo transplantation of 3/A/1D-1 chondroprogenitor mouse teratocarcinoma cells. The 3/A/1D-1M cell cultures exhibited a triphasic evolution: after reaching confluence (day 3), cultures developed well-delimited cell clusters (days 6-8), which ultimately were organized into multilayered nodules (days 12-15).

Expression of collagen, osteocalcin, and bone alkaline phosphatase in a mineralizing rat osteoblastic cell culture.

Rat calvaria bone cells isolated by collagenase digestion form a bone-like matrix which mineralizes in vitro in the presence of beta-glycerophosphate, in less than 2 weeks. The purpose of this work was to investigate, in this mineralizing rat osteoblastic cell culture, the synthesis of collagen, osteocalcin, and bone alkaline phosphatase (ALP). The results obtained indicate (1) After 15 days in culture, the extracellular-matrix contains collagen type I, V, and to some extent type III.

[Bacterial interaction in periodontal diseases].

The aim of this review is to study the different interactions between human oral bacteria which, through specific mechanisms such as coaggregation, contribute to increase periodontal disease.

[An epidemiologic study of the oro-dental health status of children in the region of Ile de France].

An epidemiological survey was conducted of the oral conditions in the region of lle de France of a representative sample of 2,062 children aged 6 to 15 years. The sample was selected among the population of Paris and the departments of Hauts de Seine, Seine St-Denis, Val-de-Marne, Val d'Oise and Seine et Marne; 1,962 children came from urban zones. The mean DMFT increased with age and was 0.

Collagen expression during teratocarcinoma cell line-induced endochondral bone tumor.

Collagen immunotyping by indirect immunofluorescence was performed in order to investigate the sequential development of bone formation. Osseous tumors were obtained after subcutaneous injection of 3/A/1D-1 teratocarcinoma cell line into 129/Sv mice (Nicolas et al., 1980).

Mineralization in vitro of matrix formed by osteoblasts isolated by collagenase digestion.

Osteoblasts from calvaria of 18-day-old fetal Sprague-Dawley rats were isolated using a dissecting procedure followed by collagenase digestion. Freshly isolated or previously frozen cells were cultured for up to 4 weeks in a Dulbecco's modified Eagle's medium supplemented with 10% fetal calf serum and 50 micrograms/ml ascorbic acid, with or without 10 mM beta-glycerophosphate. Most of the cells were alkaline phosphatase positive throughout the culture period and expressed a type-I collagen as assessed by immunofluorescence.

Collagen synthesis in mouse embryonal carcinoma cells: effect of retinoic acid.

In five lines of mouse embryonal carcinoma cells, PCC3/A1, PCC4, PCC4/Aza-R1, and F9, collagen synthesis was examined by immunofluorescence reaction using specific antibodies directed against collagen. All the embryonal carcinoma cell lines showed type IV collagen, and PCC7-S/Aza-R1 revealed the additional presence of type III collagen. When the F9 and PCC3/A1 EC cells were treated with retinoic acid and dibutyryl-cAMP, they differentiated into morphologically different cellular types.
