1/3. Plaque control in the treatment of juvenile periodontitis.With the purpose of establishing to what extent "periodontosis" responds to total plaque control, 21 such patients were observed over periods ranging from 8 to 34 years. Total plaque control in the present context means complete removal of all supragingival plaque by the patient and complete removal of all subgingival plaque by the dentist. The results were evaluated in terms of the number of lost teeth and the percentage of lost attachment during the observation period. It was observed that "periodontosis" cases responded to total plaque control in the same way as do ordinary cases, but with periodontosis, incomplete plaque control on any teeth led to extremely rapid bone loss and eventually to extraction. The reason for this is the unusually rapid apical migration of the subgingival plaque which is the most typical feature of the juvenile periodontitis. Some attachment and some teeth were lost in most of the patients, but a sufficient number of teeth with a sufficient amount of supporting tissue were maintained to provide a set of natural teeth that functioned well. This study shows that the reduced resistance to the invasion of subgingival plaque can be compensated for by a correspondingly strong emphasis on total plaque control. The term "periodontosis" is misleading, and should be replaced by the name "juvenile periodontitis" as suggested by Lehner et al.

2/3. Precocious periodontitis: a clinical entity and a treatment responsibility.This report has proposed that the term, periodontosis, be discarded and replaced with the term, precocious periodontitis. The literature review has shown that, although the exact causative agents are unknown, certain microbiological reactions do occur and the condition is a periodontitis. The term, precocious periodontitis, has been suggested because the disease entity differs from chronic periodontitis in some of its characteristic features and etiologic factors. Three important local etiologic factors are: (1) contact and eruption of the first molars, (2) occlusal traumatism, and (3) ineffective oral hygiene. The recent literature concerning possible hereditary characteristics, bacteriological findings, and immunological reactions has been cited. The reports presented showing successful results of therapy were selected to illustrate that this condition can have the same prognosis and response to therapy as other similarly involved cases of periodontitis as a clinical entity with a definitive treatment responsibilities.- - - - - - - - - - ranking = 1.5keywords = periodontitis (Clic here for more details about this article) |
3/3. Lack of effect of citric acid treatment of root surfaces on the formation of new connective tissue attachment.Previous reports have described an accelerated induction of new attachment and repair of furcations in dogs after treatment of roots surfaces with citric acid, but few controlled clinical studies have examined its usefulness in surgical treatments for periodontitis. This study compared the effects of a comprehensive surgical plaque control procedure with or without citric acid treatment for generalized and localized effects on gingival height, probing pocket depth and attachment level in 72 teeth in 3 patients who were treated surgically for moderate periodontitis and examined every 3 months for 1 year. No statistically significant differences in the effects of the 2 treatments were observed. These observations suggest that there is no clinical advantage of citric acid conditioning of the root surface during surgical treatment of periodontitis.- - - - - - - - - - ranking = 0.5keywords = periodontitis (Clic here for more details about this article) |
