“…The data demonstrate marked differences in the trabecular bone composition at different skeletal sites with regard to their mineral components and their content of skeletal proteins. Several factors may contribute to this heterogeneity of the bone composition, including differences between bone cell populations derived from different skeletal sites (Kasperk et al 1995), differential biomechanical strain (Lean et al 1995), and/or local differences in the vascular supply of bone (Bradly 1975). Alterations in the concentration of bone components, both minerals and collagenous or noncollagenous proteins, can have significant effects on the mechanical behavior of the bone tissue, and thus make the bone more (or less) resistant to fracture (Burstein et al 1977, Leichter et al 1982, Currey et al 1996.…”

Skeletal site-related differences in trabecular bone composition have been studied in autopsy samples from 63 individuals (age range 23-92 years). From each individual, bone samples were excised from the iliac crest, lumbar spine, femoral neck, and calcaneus. Samples were analyzed for their content of ash, calcium, collagen, extractable proteins, osteocalcin, and IGF-I. Significant differences were found between the skeletal sites, the lumbar spine being the least mineralized site and the femur the most. The femur and lumbar spine had a higher osteocalcin and IGF-I content compared with the other skeletal sites, suggesting a higher bone turnover rate. The intercorrelations between the anatomical sites were low for minerals and collagen but high for osteocalcin and IGF-I. The latter might indicate that the presence of these proteins in the bone matrix is mainly controlled by endocrine mechanisms which may influence the osteoblast function. Finally, regression analysis showed a significant age-related decrease of skeletal IGF-I at all sites examined. This finding supports the hypothesis of an IGF-I-mediated pathogenesis of senile osteoporosis. In summary, our data imply that a global assessment of skeletal function and bone quality, based upon analyses at one anatomical site, should be applied with caution.

“…The pattern of the blood supply in the mandible is thought to change from one that is largely centrifugal in the young dentate individual, to one that is primarily centripetal, with the supply being increasingly dependent upon periosteal and submuscular sources by the time old age is reached (Castelli, 1963;Wallenius and Heyden, 1972;Bradley, 1975Bradley, , 1981Poirot et al, 1986). This is likely to be of immense importance if the mucosa is used to support a denture (Weinmann and Sicher, 1955;Ortman, 1962), since prolonged pressure could occlude the fine periosteal plexus of vessels.…”

Following tooth loss, the mandible shows an extensive loss of bone in some individuals. This may pose a significant problem in the prosthodontic restoration of function and esthetics. The many factors which have been proposed as being responsible for the inter-individual variation in post-extraction remodeling mean that a perfunctory analysis of the literature, in which well-controlled, relevant studies are scarce, may not provide the whole story. This article reviews the local and systemic factors which may play a role in the post-extraction remodeling of the mandible. Since severe residual ridge resorption may occur even when the bone status in the rest of the skeleton is good and vice versa, it is concluded that local functional factors are of paramount significance. It is now essential to determine how they can be modified and applied to help maintain ridge height and quality in our aging, edentulous population.

“…On peut observer un retard d'érup-tion, des agénésies, des dents incluses, des aplasies dentaires, des malformations coronaires et radiculaires, des hypoplasies de l'émail, une absence de desmodonte, une hypominéralisation de la dentine et de l'émail rendant les dents extrê-mement sensibles aux caries, un épaississement de la lamina dura, ainsi qu'une chute prématurée des dents [85,[158][159][160][161][162] . Les anomalies dentaires apparaissent avec l'éruption des premières dents : elles se traduisent par un retard d'éruption et une ankylose qui s'aggravent au cours des années.…”

“…Bien que la transplantation de moelle osseuse ait pu sensiblement améliorer plusieurs cas d'ostéopétrose maligne, elle ne permet pas de rétablir chez l'homme, contrairement à ce qui a pu être démontré chez le rat op, l'éruption des dents ankylosées [162,170] . L'absence de ligament alvéolo-dentaire n'est pas uniquement observée sur les dents incluses ; sur les dents ayant eu une évolution apparemment normale le desmodonte est bien souvent remplacé par une membrane fibreuse [160,161,167] . Cette dernière n'assure pas un ancrage correct de la dent sur l'os, et il n'est pas rare de constater la chute prématurée de dents 2 à 3 ans après leur éruption [160] .…”

“…Le plus souvent, elles ont été présentées en deux groupes principaux comme s'il n'y avait que deux formes cliniques, bénigne et maligne. En réalité, neuf formes ont déjà été identifiées chez l'homme, et les manifestations stomatologiques sont rarement spéci-fiques d'une forme particulière d'ostéopétrose [6,81,[158][159][160][161] . Le degré d'atteinte des maxillaires est variable: macromandibulie, prognathisme et malformations palatines sont parfois retrouvés, indé-pendamment de la forme clinique considérée [85,[158][159][160][161] .…”

RÉSUMÉLes manifestations stomatologiques de l'ostéopétrose sont nombreuses. Elles intéressent la structure osseuse des maxillaires mais aussi l'organe dentaire : malformations diverses, troubles de l'éruption dentaire, et anomalies du ligament alvéolo-dentaire ; ces dernières sont probablement responsable de la chute prématurée des dents. Les manifestations osseuses sont secondaires à l'hyperminéralisation osseuse et à l'hypovascularisation qu'elle induit. A côté de la fragilité bien connue de l'os, on retrouve un risque accru d'ostéomyélite des maxillaires dont la prise en charge se révèle souvent difficile. Une meilleure compréhension de la physiopathologie de l'ostéopétrose et l'identification des facteurs favorisants l'ostéomyélite devraient permettre de proposer des mesures adéquates pour prévenir cette redoutable complication.
