The plaque control record

Abstract: A N U M B E R OF examination systems have been developed to record the oral hygiene status of an individual. Most systems use either selected teeth or the highest score for a group of teeth within a segment as the basis for their scores. When used for epidemiological studies or for evaluating the results of treatment in a study group these methods yield useful information. A numerical score, however, is of limited value for the clinician treating an individual patient. He is concerned with the locations where plaque accumulates and in the patient's progress in learning how to effectively clean these surfaces.

The Relationship Between the Width of Keratinized Gingiva and Gingival Health

Abstract: Thirty-two dental students between 19-29 years of age with no pathologic pockets performed supervised oral hygiene (daily supervision with the Plak-Lite® dis­ closing system) 3 1 for 6 weeks. Following this period, the gingiva of all buccal and lingual tooth surfaces was assessed using the Gingival Index system. 2 Oral hy­ giene was scored on all surfaces according to the criteria of the Plaque Index system. 3 The identification of the mucogingival junction was facilitated by staining with Schiller's IKI solution. 3 4 Using this method, the epithe­ lium of the alveolar mucosa yielded an iodine-positive reaction while the keratinized gingiva was iodine-nega­ t i v e , 3 4 3 6 (Figure 1 a,b). After application of the Schiller solution, the width of keratinized gingiva was measured FIGURE 1.

The Periodontium of Ageing Humans

Abstract: T H E R E IS LITTLE INFORMATION on the periodontium of ageing humans. Patients in the fifth, sixth, and seventh decades of life, and older, are viewed with caution by dentists. Their treatment, however, is much the same as that given to younger adults. The main differences are that extensive elective surgery is avoided and fewer complex restorations are placed. This approach is probably based on the thought that the older patient may not be able to endure extensive dental treatment or even that he doesn't have long to live. It is not based on any broad knowledge of the dento-periodontal structures of the aged and their functional and reparative capacities.

Formation of the Periodontal Ligament

Abstract: Since the report by Fischer, a number of varying and often conflicting descriptions have appeared on periodontal ligament formation. These reports tend to be fragmentary and do not record the detailed morphological changes in various stages of the developmental sequence. Some investigators suggest that the principal fiber bundles develop from the dental fol l ic le 2 , 9 , 1 0 while others disagree. Some reports describe the "intermediate p lexus" 1 , 2 , 3 , 7 while others deny its existence. Faced with both incomplete evidence and controversy, a rather general view of the development of the periodontal ligament has been postulated. Ten Cate states: "There is general agreement that the fiber bundles of the periodontal ligament develop in relation to alveolar bone and cementum. Ultimately these fiber bundles meet in the forming ligament and it is in part this union of separate fiber bundles which has generated the concept of an 'intermediate plexus' " . 1 7
