11/12. Host defensive functions in a family manifesting early-onset periodontitis.family case studies help us identify host risk factors in periodontal disease. In this study we examine a family consisting of a mother (40 years old, with rapidly progressive periodontitis), her elder daughter (14 years old, with localized juvenile periodontitis), and younger daughter (13 years old, with simple gingivitis). We examined 1) the peripheral neutrophil functions (chemotactic migration, phagocytosis, superoxide production); 2) lymphocyte functions (proliferative activity and cytokine productivity of T cells, immunoglobulin [Ig] M productivity of B cells when stimulated with pokeweed mitogen); 3) phenotypic analyses of peripheral lymphocyte subpopulations; 4) serum IgG antibody titers against periodontopathic bacteria; and 5) serological type of HLA class II. All the subjects exhibited high T4/T8 ratios due to high percentage of CD4-positive cells, showed high IgG titers to actinobacillus actinomycetemcomitans, and had a HLA DQw1 in common. The mother showed a slight deficiency of neutrophil chemotactic migration to N-formyl methyonyl leucyl phenylalanin (fMLP), raised interleukin-2 productivity of T cell, and high levels of IgG titers to Porphyromonus gingivalis and fusobacterium nucleatum. Both daughters showed weak T cell proliferative response to anti-CD3 monoclonal antibody and low IgM productivity. Low lymphocyte responsiveness may be involved in the pathogenesis of periodontal disease of these daughters; therefore, the lymphocyte dysfunctions shown should be considered in relation to the progression of periodontal disease.- - - - - - - - - - ranking = 1keywords = progression (Clic here for more details about this article) |
12/12. Complications associated with diabetes mellitus after guided tissue regeneration: case report.Dental practitioners need to be aware of the complications that can arise in the management and treatment of patients with diabetes mellitus. patients with diabetes, and patients with a family history of diabetes, are at-risk dental patients. They are more likely to develop periodontal disease, and the periodontitis is more likely to be severe. Diabetes influences the progression and severity of periodontitis through changes in the small blood vessels, decreased collagen formation, and impairment of the host's defense mechanisms. Furthermore, complications associated with diabetes, such as impaired wound healing, can affect the patient's response to periodontal therapies like guided tissue regeneration (GTR). The case report in this article discusses the postsurgical complications that occurred during GTR treatment of a patient with non-insulin-dependent diabetes. The diabetic's susceptibility to periodontal disease and impaired wound healing can affect the progression of the disease and its treatment. Dental patients with diabetes require close supervision and frequent monitoring of their medical and dental health by the dental clinician.- - - - - - - - - - ranking = 2keywords = progression (Clic here for more details about this article) |
