Validation of a French version of the Child-OIDP index.

The Child-OIDP index is an indicator of oral health-related quality of life, which has been validated among 12-yr-old children in Thailand. The aim of this study was to assess the reliability, validity, and applicability of this questionnaire among French children. After translation and cultural adaptation, the Child-OIDP was tested on 414 10-yr-old children in France. The children completed the Child-OIDP in face-to-face interviews, were clinically examined, and answered questions evaluating their global self-rated oral health. Parents filled in a questionnaire concerning their socio-demographic background. An oral impact on daily life was reported by 73% of the children. The mean Child-OIDP score was 6.32 [standard deviation (SD) 8.22] and the median was 3.33. The internal reliability was confirmed with a Cronbach's alpha of 0.57. The retest procedure (n = 62) showed a satisfactory reproducibility (r = 0.81, kappa = 0.75). The index was shown to be a valid instrument. Construct validity was satisfactory as the Child-OIDP score increased when the children's perceived oral health decreased. The Child-OIDP score was able to discriminate between different socio-demographic groupings and varied according to dental status. This study showed that the Child-OIDP is applicable for use among children in France. It has promising psychometric properties but further research is required to evaluate its sensitivity to change.

Primate dentine extracellular matrix induces bone differentiation in heterotopic sites of the baboon (Papio ursinus).

In rodents, demineralized dentine matrix induces local differentiation of endochondral bone. This study investigated the osteoinductive potential of primate dentine matrices when implanted extraskeletally in allogeneic recipients. Demineralized dentine cylinders prepared from adult baboon incisors and demineralized dentine matrix pulverized to a particle size of 74-420 microns were implanted into the rectus abdominis of 4 subadult male baboons (Papio ursinus). Specimens were harvested 30 and 90 d after implantation. Histological analysis on serial sections showed bone differentiation in demineralized dentine cylinders after partial resorption of the external demineralized layer, and in resorption lacunae and excavation chambers within the matrix. Implants of demineralized dentine matrix of 74-420 microns particle size showed no osteoinductive activity as determined biochemically (alkaline phosphatase activity) and histologically. The demonstration of bone induction by primate dentine prepared from fully erupted tooth matrix suggests that putative osteogenic proteins may be conserved after dentinogenesis and embryonic tooth development, and may play a role during healing after surface demineralization of exposed root surfaces during regenerative procedures in humans.

Intra-alveolar surgical uprighting of impacted teeth: a case report.

Although orthodontic repositioning of impacted teeth is widely used, the treatment has its limitations. Autotransplantation or intra-alveolar surgical repositioning of teeth is an alternative therapy that may be used in selected cases of desperate impactions, when orthodontic extrusion is unsuccessful or when orthodontic treatment is rejected by the patient. A case report is presented to stress both the indications and limitations of a modified technique of intra-alveolar surgical uprighting of impacted teeth.

Dental characteristics of the Wolf-Hirschhorn syndrome: a case report.

Little attention in the dental literature has been given to the dental characteristics of patients with the Wolf-Hirschhorn Syndrome (WHS). The syndrome is caused by deletions of the terminal portion of the short arm of chromosome 4. This case report provides information on dental anomalies noted in a child with WHS. The dental findings include agenesis of multiple permanent teeth, particularly premolars and molars, taurodontism, and over-retained primary teeth. This syndrome exhibits variable clinical expressivity, possibly due to the extent and the specific locus of the chromosomal deletion. Further studies are required to obtain a clearer view of the clinical oral/dental manifestations of this syndrome.

Familial malignant osteopetrosis in children: a case report.

The clinical, radiological, pathological and laboratory findings of two brothers with autosomal recessive malignant osteopetrosis are presented. Our findings are similar to characteristics previously reported in the literature about patients with osteopetrosis. The 6-year-old male patient was pale and had petechiae on his arms and legs. He also had macrocephalia, splenomegaly, severe pancytopenia, genu valgus, hypocalcemia, amaurosis, cessation of physical development, generalized bone sclerosis and recurrent infections with a history of multiple incidences of acute otitis media. Generalized bone sclerosis and irregular sclerosis of the maxilla and mandible were seen on radiographs. The oral mucosa was apparently normal but permanent tooth eruption was delayed although there was early loss of deciduous teeth. The recommended treatment was blood transfusion and therapy with antibiotics when necessary; a bone marrow transplant was not possible due to lack of a compatible donor.

Comparison of mesiodistal crown diameters of the deciduous and permanent teeth in Australian aboriginals.

Mesiodistal crown diameters of corresponding deciduous and permanent teeth were compared in 106 male and 66 female Aboriginal subjects from Yuendumu in the Northern Territory of Australia. On average, the size relationships were similar to those reported for Caucasoid groups but there was considerable variation between subjects, particularly in the deciduous first molar--permanent first premolar comparison.
