Morphological aberrations of the width of attached gingiva and their influence

Since many years, a great number of studies have been discussing the role of attached gingiva in marginal periodontal behavior, either accepting that a minimum of 2.0 mm of width is required to maintain marginal periodontal health or suggesting that width is negligible if excellent oral hygiene is performed, yet areas with narrow width of attached gingiva seem to be prone to periodontal attachment loss. Therefore the main aim of our study was to determine the influence, if any, of different widths of attached gingiva on attachment loss. The survey was carried out on 209 lower incisor due to extraction. Prior to extraction plague index, index of gingival bleeding upon probing, and gingival inflammation (Sillnes Loe) were noted for each tooth. Afterwards the width of attached gingiva in lower vestibule was measured. After extraction the periodontally involved part of the root was carefully scaled and cleaned in running water and then stained for 10 seconds in 0.1% toludine blue to facilitate the measurement of attachment loss. Loss of attachment was then measured along the long axis of the tooth from cemento–enamel junction to the most coronal level of the stained periodontal ligament on the vestibular, distal and lingual surface. Obtained data were divided into two groups according to the previously measured width of attached gingiva. -Group1 teeth extracted from regions with attached gingiva equal or more than 2 mm (n=115) -Group2 teeth extracted from regions with attached gingiva less than 2 mm. (n=94) Obtained data showed statistically significant higher values of plague and gingival indices for the second group. Attachment loss was significantly higher in regions with inadequate width of attached gingiva
