Relationship between dental knowledge and tooth cleaning behavior.

A study was carried out to determine whether knowledge about dental health is related to dental behavior in a group of patients who have a positive attitude towards their dental health. Recall patients attending a clinic for periodontal care were asked to fill in a questionnaire to assess: 1) attitudes and beliefs, and 2) dental knowledge and reported behavior. They were then examined to assess their gingival health and plaque control (actual behavior). 161 patients were seen in Social Classes 1-3. Responses to the attitudinal questions indicated that approximately 80% of the patients had positive attitudes. Patients were grouped (1-5) according to Gingival Index scores (range 0.13-1.83). None of the attitudinal concepts tested were associated with the lower GI groupings. Correct knowledge about gingival disease and reported higher frequency of cleaning did not show correlation with the lower GI groupings. No significant relationship could be determined between positive attitudes and knowledge levels as predictors of gingival health.

Periodontal disease and type I diabetes mellitus in children and adolescents.

This study compared the periodontal status of a juvenile diabetic study group with that of a non-diabetic control group similar in age and sex. The study group consisted of 26 type I diabetic patients with an average age of 13.42 years and 24 control subjects of similar age. The diabetic subjects were evaluated with glycosylated hemoglobin (GHb) to obtain a measure of diabetic control. Clinical periodontal evaluations were performed for all teeth in each subject, and consisted of the plaque index, gingival fluid flow, gingival index, probing depths, clinical attachment levels, recession, and bleeding on probing. Analysis of the data demonstrated no statistically significant differences in the overall means for the 2 groups for average attachment loss, probing depths, recession, gingival index, plaque index, gingival fluid flow, or bleeding on probing. There was no significant association between the level of control of diabetes (GHb) and clinical variables. However, comparisons based on site-specific measurements showed the gingival index to be somewhat higher among the diabetics (p = 0.0002), and examination of interaction effect plots showed the diabetic group to have higher average gingival index for most teeth and higher or the same plaque index levels on all teeth relative to controls. Thus, a young study population with type I diabetes mellitus was found to have significantly increased severity of inflammatory gingival disease compared to controls of similar age.

Root coverage with the free gingival graft. Factors associated with incomplete coverage.

The free soft tissue autograft when used for increasing the amount of attached gingiva is a relatively simple surgical procedure. The use of the free soft tissue autograft for root coverage, however, is a much more technically demanding procedure requiring the periodontist to consider additional factors. Overlooking or failing to properly address a single one of these factors can result in incomplete coverage. The purpose of this paper is to outline those factors that must be considered when complete root coverage is attempted.

Novel ceramides recovered from Porphyromonas gingivalis: relationship to adult periodontitis.

The primary purpose of this study was to characterize the major structural features of ceramides recovered from Porphyromonas gingivalis, a suspected periodontal pathogen. Complex lipids extracted from P. gingivalis were treated with N, O-bis(trimethylsilyl)-trifluoroacetamide and analyzed using gas chromatography-mass spectrometry. Mass spectra of lipid derivatives revealed cleavage products consistent with structures of four major ceramides. Two of the major ceramides are proposed to contain long chain bases of either 2-amino-1,3-octadecanediol or 2-amino-1, 3-nonadecanediol in amide linkage to 3-hydroxy isobranched C17:0. The remaining major ceramides are proposed to contain either 2-amino-1,3-octadecanediol or 2-amino-1,3-nonadecanediol in amide linkage to C17:1. Alkaline hydrolysis of P. gingivalis lipids and subsequent formation of suitable derivatives revealed 3-hydroxy isobranched C17:0, C17:1, 2-amino-1,3-octadecanediol, and 2-amino-1, 3-nonadecanediol as hydrolysis products. Therefore, the constitutive fatty acids and long chain bases recovered in alkaline hydrolysis products of P. gingivalis lipids are consistent with the proposed ceramide structures. The next goal of this study was to investigate whether these bacterial ceramides exist in lipid extracts of human teeth and gingival tissue at sites of severe adult periodontitis. Using selected ion monitoring of characteristic ions and retention times for each ceramide described above, lipids from teeth and gingival tissue were shown to contain primarily the ceramides containing C17:1. It is concluded that P. gingivalis synthesizes at least four major ceramides and two of these ceramides are selectively adsorbed to diseased tooth surfaces and may penetrate into diseased gingival tissue.

Molecular identification of an invasive gingival bacterial community.

A woman with neutropenia developed gingival hyperplasia. Biopsy showed invasion of gingival tissue with mats of filamentous organisms, and molecular analysis by polymerase chain reaction and fluorescence in situ hybridization revealed Capnocytophaga sputigena, Leptotrichia species, and Fusobacterium nucleatum. Oral bacterial flora may cause invasive gingival disease with hyperplasia in immunocompromised patients.
