Mechanisms of Bone Resorption in Periodontitis.

Alveolar bone loss is a hallmark of periodontitis progression and its prevention is a key clinical challenge in periodontal disease treatment. Bone destruction is mediated by the host immune and inflammatory response to the microbial challenge. However, the mechanisms by which the local immune response against periodontopathic bacteria disturbs the homeostatic balance of bone formation and resorption in favour of bone loss remain to be established.

Prevalence of clinically relevant oral mucositis in outpatients receiving myelosuppressive chemotherapy for solid tumors.

Purpose: Chemotherapy-induced oral mucositis (CIOM) is a common side effect of cancer therapy that may lead to significant morbidity and interfere with the treatment plan. The present prospective, cross-sectional study intended to describe the prevalence of clinically relevant CIOM (CRCIOM) in outpatients receiving chemotherapy for solid tumors.

Methods: Intra-oral assessments were performed on 298 consecutively recruited patients, who had undergone at least 14 days of chemotherapy for solid tumors in our outpatient oncology department.

Labial piercing and localized periodontal destruction - partial periodontal regeneration following periodontal debridement and free gingival graft.

Localized periodontal destruction has been reported as a rare complication of intraoral piercings. The purpose of this case report was to illustrate the destructive nature of a lip stud and to describe the successful treatment of this case. The lip stud was removed and supra- and subgingival debridement was performed.

Quantification of bone resorption in the interforaminal region of the atrophic mandible.

Purpose: This anatomic study was undertaken to examine the effects of atrophy on bone quantity and quality in the mandibular interforaminal region.

Materials And Methods: Three sections were made from each jaw studied, and each section was measured by means of a morphometric software program (Artma-Biomed, Vienna, Austria). The mandibular specimens were grouped according to the classification of Cawood and Howell and also according to that of Lekholm and Zarb.
