摘要:

Abstract.A detailed review of periodontal dressings is presented, covering physical, chemical and biological aspects. Areas requiring further research are outlined, particularly in the physico‐chemical sphere; and some contra‐indications to particular substances are described. It is concluded that there is a definite place for dressings, but that more knowledge is required before optimal properties can be develo

摘要:

Abstract.An experimental clinical trial design is described in which the onset of gingival bleeding was used as an indicator of early gingivitis. Twenty‐nine dental students participated in a double‐blind crossover trial utilising chlorhexidine as a known plaque inhibitor. The onset of gingival bleeding was assessed in three ways, one of which yielded a statistically significant difference in favour of the active mouthrinse (P =0.02). The method has a role in screening agents believed to be active against gingivi

摘要:

Abstract.A surgical technique to establish wide zones of attached mucosa was performed in 28 patients presenting with inadequate amounts of attached gingiva. The clinical results of the procedure were monitored over a period of 2 years. Biometric assessment of 112 mucogingival units immediately before and at 1, 3, 6, and 24 months after surgery revealed that the mean width of attached gingiva changed from 1.1 mm to 5.3 mm of attached tissue (gingiva plus vestibular mucosa). A surgically produced increase of 4.9 mm in width (P<0.001) and subsequent shrinkage of 0.7 mm or 14 % (P<0.01) resulted in a total averagegain oj 4.2 mm of attached mucosa 2years after surgery (P<0.001). A begin/end analysis ofthe coronal level of clinical periodontal attachment and the extent of gingival recession showed no clinically significant changes. The meanwidth of keratinized gingiva increased 0.8 mmduring the 2‐year postoperative period. The subperiosteal vestibule extension is recommended as an alternative to the free autogenous mucosa graft for establishing wide bands of attached mucosa in areas where loss of attached gingiva is associated with mechanical or microbial irritation of the marginal periodontiu

摘要:

Abstract.Thirty‐six subjects with no evidence of clinical gingival inflammation underwent a standardized toothbrushing procedure. Blood specimens, obtained from a vein in the antecubital fossa during the last 30 seconds of brushing, were cultured under aerobic and stringent anaerobic conditions. Three subjects exhibited detectable bacteraemias,Propionibacterium sp. being isolated from two of the subjects, whileAclinomyces sp, Streptococcus sanguisandStreptococcus mitiswere isolated from the third. The implications of these results are discusse

摘要:

Abstract.The objective of this study was to determine if the regular vascular network previously reported as occurring in noninflamed marginal gingiva would become re‐established following plaque control and treatment of gingiva by gingivectomy and scaling.Gingivectomies were performed on dogs with and without pre‐experimental gingivitis in order to obtain gingival specimens healed for 4, 8 and 12 weeks. Plaque was controlled using toothbrushing and topical applications of 0.2 % chlorhexidine gluconate. After 12 weeks, the animals were perfused via the carotid arteries with glutaraldehyde and Microfil® latex compound. Specimens were processed for either routine histology or examination of vascular morphology in methyl salicylate cleared tissues. The absence of inflammation in healed gingiva was evaluated clinically, using the Gingival and Plaque Indices, and histologically.Results showed that in healed clinically and histologically noninflamed gingiva, the vascular morphology was established as a series of looped vessels which could readily be distinguished from the regular network of vessels described by Hock (1975) in marginal gingiva that had neither been inflamed nor rese

摘要:

Abstract.The purpose of this study was to assess whether fixed splinting aided in the reduction of posterior tooth mobility during initial therapy. A “split‐mouth” approach was used in order to compare splinted segments with similar unsplinted segments. Seven patients were selected, all of whom demonstrated chronic destructive periodontitis and mobile teeth. Initial therapy, consisting of oral hygiene instruction, root curettage and occlusal adjustment, was performed over a 2‐week period. At the time of initial therapy, teeth in contralateral segments were splinted with an intracoronal wire‐and‐acrylic splint. Tooth mobility and gingival inflammation were recorded in all four segments every 3 weeks for a 15‐week monitoring period following initial therapy. The splints were removed before each data recording session and then replaced and the occlusion refined. Prophylaxis and oral hygiene instruction were repeated every second week throughout the monitoring period. The reduction in the mobility of teeth splinted during the entire therapy period did not differ from the reduction observed in the unsplinted segments. The reduction in tooth mobility observed in both the splinted and unsplinted segments over the 17‐week period can be attributed to the improved occlusal relationships and reduction
