One beagle dog with a healthy periodontium was used in the study. The maxillary right first and second molars and the mandibular left first and second molars acted as the experimental group in which furcation perforations were treated by guided tissue regeneration. The maxillary left and mandibular right first and second molars served as the controls in which furcation perforation lesions were only treated by open flap debridement. Clinical, histological, and standardized radiographic evaluation showed significant differences between the test and control groups. In addition, digital subtraction radiography revealed a gain in alveolar bone height and increased density at all experimental sites, and a loss at all control sites. Histological evaluation showed extensive regeneration of both alveolar bone and connective tissue at experimental sites, but none at control sites. The results of this study suggest that the use of guided tissue regeneration in furcation lesions produced by endodontic perforations will result in significant new bone and connective tissue attachment.","PeriodicalId":77319,"journal":{"name":"Periodontal clinical investigations : official publication of the Northeastern Society of Periodontists","volume":"19 2","pages":"9-15"},"PeriodicalIF":0.0,"publicationDate":"1997-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"20420309","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study group consisted of 12 systemically healthy patients with bilateral mandibular furcation defects with attachment loss > or = 6 mm; one site was randomly assigned for GTR treatment while the contralateral site received surgical flap debridement only. Subgingival plaque samples were collected by paper point on the day of surgery and at 2, 4 and 6 months post-surgery. Three sites were sampled in each patient: a collagen membrane site, a control surgical site, and an unoperated control site. Plaque samples were transported in a non-phosphated buffer solution and examined by phase-contrast microscopy. Cocci, rods, spirochetes, fusiforms, curved rods, and total bacteria were recorded per 10 high-power fields. Following statistical analysis utilizing the Bonferroni (Dunn) t test, no differences in total bacterial counts were found among the sites at any of the time intervals examined. Total bacterial counts were found lower at both the collagen membrane and control surgical sites post-surgery as compared to unoperated control sites, but these differences were not statistically significant (P > .05). In addition, no significant differences were detected in bacterial profiles between sites or individual time points. Results from this 6-month limited clinical trial suggest that the placement of an absorbable collagen membrane as part of a standard surgical regimen for GTR therapy does not alter the local microflora.","PeriodicalId":77319,"journal":{"name":"Periodontal clinical investigations : official publication of the Northeastern Society of Periodontists","volume":"19 1","pages":"27-35"},"PeriodicalIF":0.0,"publicationDate":"1997-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"20420305","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The major etiologic factor has been identified as microbial plaque. In periodontally treated patients, significantly higher root caries prevalence and incidence have been found in patients with high levels of Streptococcus mutans and Lactobacilli in saliva. Reducing the levels of S. mutans and Lactobacilli in saliva may lower the risk of root caries development. The purpose of this investigation was to determine the effect of an oral enzymatic rinse on the salivary counts of S. mutans and Lactobacilli in periodontally treated patients. Fifteen adult subjects participated in a double-blind, cross-over designed clinical trial. Each subject had previously undergone comprehensive periodontal therapy and had been maintained on a regular program of supportive periodontal therapy. Paraffin-stimulated whole saliva was collected from each participant. Each subject was then randomly given either the enzymatic rinse product or a control rinse and instructed to rinse with one tablespoonful twice a day for 2 weeks, after which saliva samples were taken. After a washout period, salivary samples were again taken, and the subjects received the alternate rinse product. Two weeks later, final salivary samples were taken. The salivary samples were serially diluted and incubated aerobically on selective culture media. S. mutans and Lactobacilli were counted on the basis of colonial morphology. Pretreatment and posttreatment salivary counts of S. mutans and Lactobacilli were analyzed using the Wilcoxon matched-pairs signed-rank test at the 5% level of significance. Analysis of data revealed that neither the test nor the control rinse significantly lowered salivary counts of either species in the sample population.","PeriodicalId":77319,"journal":{"name":"Periodontal clinical investigations : official publication of the Northeastern Society of Periodontists","volume":"19 2","pages":"17-21"},"PeriodicalIF":0.0,"publicationDate":"1997-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"20420310","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
