Background: Hajdu-Cheney Syndrome (HCS) is a rare hereditary bone metabolism disorder characterized by acro-osteolysis, short stature, craniofacial changes, periodontitis and premature tooth loss. Extensive search of the current literature revealed no reports of implant placement in patients with HCS.
Case Report: A 22-year old woman with osteoporosis, generalized advanced chronic periodontitis and premature tooth loss was referred to the Postgraduate Clinic of Periodontology, University of Athens-Greece.
During the last three centuries since the identification of periodontal disease, various non-surgical and surgical forms of periodontal therapy have been described and documented in the dental literature. The main objective of periodontal treatment has been initially the removal of "diseased gingiva," either through the implementation of various surgical techniques, or through the application of caustic drugs or pressing patches. Although the differences in the suggested techniques created significant controversies between some of the greatest clinicians and researchers in dentistry, their main goals remained the rehabilitation of the oral cavity and the therapeutic management of the problems sustained from periodontal disease.

- The study investigates the expression of eNOS and CD105/endoglin in pyogenic granulomas (PGs) to understand their role in the lesion's blood vessel formation.
- Approximately 93 PG samples were analyzed, with findings showing strong eNOS expression in most cases and a significant correlation with patient age.
- Results indicate differing levels of eNOS and CD105/endoglin expression in PGs compared to related tumor types, suggesting these proteins may play a role in the angiogenesis of oral pyogenic granulomas.
Background And Objective: Limited information is available on the expression and distribution of syndecan-1 within human gingival tissues/cells and on putative factors that might affect its expression. Therefore, the objective of the present study was to determine immunohistochemically the expression and distribution of syndecan-1 in the gingival tissues of patients with chronic periodontitis and to examine the correlation of syndecan-1 expression with various putative factors (environmental, patient/systemic and local factors).
Material And Methods: Gingival specimens were surgically excised from the area of the junctional/pocket epithelium (study group 1, including 30 chronic periodontitis patients) or the gingival oral epithelium (study group 2, comprising another 30 chronic periodontitis patients), adjacent to teeth with poor prognosis.
Purpose: This article reviews available data on the outcome of dental implants in osteoporotic patients.
Materials And Methods: A search was performed in PubMed and completed in July 2007. The keywords "dental AND implants AND osteoporosis," "dental AND implants AND age," "dental AND implants AND gender," and "dental AND implants AND bone AND quality," with no limitations for language or year of publication, resulted in 82, 598, 94, and 541 articles, respectively.
