摘要:

AbstractAn experimental study was designed to compare the claimed antibacterial effect of Betadine® and Blend‐a‐med® Fluid with the known plaque growth inhibiting effect of a 0.2% aqueous solution of chlorhexidine digluconate (Hibitane®). Before the test period 21 dental students refrained from all active oral hygiene measures for 5 days. During the following week they cleaned their teeth mechanically with toothbrush and toothpicks. For the third week the students were divided into three experimental groups. Following closely the manufacturers' recommendations, one group rinsed their mouths four limes daily with 10 ml of Betadine, one group every 2 hours with a glassful of water containing 5–8 drops of Blend‐a‐med Fluid, and the control group twice daily with 10 ml of the 0.2 % chlorhexidine solution. Mechanical cleaning of the teeth was not allowed during the experimental week. The Plaque Index scorings decreased significantly from the end of the no‐hygiene to the end of the mechanical cleaning period. During the experimental period a further decrease of the mean PII score was recorded in the control group using chlorhexidine while in the two test groups the PII scores returned to the level recorded after the no‐hygiene period. As neither Betadine nor Blend‐a‐med Fluid proved able to prevent plaque growthin vivo, there seems to be no indication for their use in tre

摘要:

AbstractThe effectiveness of plaque disclosure by several liquid food colourants and disclosing agents was compared in a group of eight subjects. The subjects refrained from all forms of oral hygiene for a 48‐hour period prior to rinsing with 5 ml of each dye in turn at weekly intervals. Kodachrome film records were taken and projected for the assessment of plaque staining efficacy by a panel of 38 assessors. Acceptability with respect to taste, extent and duration of mucosal staining and any side effects was also evaluated.The food colourants were as effective as the disclosing agents. Ability to stain plaque appears to be related not only to the constituents of each dye, but also to their concentrations and relative proportions. Other desirable properties of an ideal disclosing agent tended to be fulfilled to a level equivalent to, or better than, that reached by the proprietary disclosing agents. Difficulty in obtaining proprietary disclosing agents should not act as a handicap to achieving better levels of oral cleanliness as inexpensive food colourants of equal effectiveness to the best proprietary agent are readily availabl

摘要:

AbstractStages in the pathogenesis of gingival recession were observed in rats in which pocketing had been induced by replacement of natural incisors with dental implants. Suitable conditions were thus created on the palatal aspect of the implant sockets for recession to occur.The recession process was examined at intervals by taking transverse serial sections. In the epithelial and connective tissues deep to the receding margin, morphological changes were seen which apparently lead to cleft formation and recession. These appeared to be associated with mononuclear cell infiltration of the connective tissue. The study suggests that gingival recession involves a localized inflammatory process which causes breakdown of connective tissue and leads to proliferation of the epithelium into the site of connective tissue destruction. Proliferation of the epithelial cells into the connective tissue brings about a subsidence of the epithelial surface, which is manifest clinically as recession.

摘要:

AbstractA previous paper described a suggested protocol which could be used for testing therapeutic measures. In this paper the protocol has been used as a basis for testing experimental toothpastes over short and medium periods of time. The effects on plaque and gingivitis of a chlorhexidine paste used for 4 weeks, and of two other experimental products used over 8 weeks, have been investigated. Statistically significant improvements in gingivitis were observed during the use of chlorhexidine and one of the experimental pastes compared with their respective placebo pastes. The benefit observed for the experimental paste became evident when the data were analyzed considering only participants with‘frank' gingivitis. The findings have also been presented in various ways in attempts to express the benefits of the therapeutic measures in clinical terms by using arbitrarily determined success criteri

摘要:

AbstractA clinical trial was undertaken to study the healing capacity of the periodontal tissues following different modes of periodontal surgery in patients whose oral hygiene was professionally maintained at an optimal level. Fifty patients, distributed into five groups, participated in the study. Following an initial examination and presurgical treatment, the various patient groups were subjected to one of the following surgical procedures: 1) the apically repositioned flap operation including elimination of bony defects, 2) the apically repositioned flap operation including curettage of the bony defects but without removal of bone, 3) the “Widman flap” technique including elimination of bony defects, 4) the “Widman flap” technique including curettage of the bony defects but without removal of bone, 5) gingivectomy including curettage of the bony defects but without removal of bone. After surgery, all patients received oral hygiene instruction and professional cleaning of the teeth once every 2 weeks during a 2‐year period.The results showed that periodontal disease can be cured and further destruction of the periodontal tissues avoided irrespective of the surgical technique utilized for pocket elimination. Different surgical techniques, however, promoted varying degrees of regeneration of the supporting tissues. The most favourable healing was obtained when resection of bone was avoided and when complete coverage of the alveolar bone wa

摘要:

AbstractThe importance of an adequate amount of keratinized and attached gingiva to maintain gingival health has been stressed by several authors (Friedman&Levine 1964, Lang&Löe 1972, Bernimoulin&Mühlemann 1973) and though the rationale for increasing the width of the gingiva applies equally well to both the lingual and the vestibular surfaces, only one report of a graft on the lingual aspect of the mandible in dentate patients has been found in the literature (Goldman&Cohen 1973).The object of this report is to describe the indications, the surgical procedure devised and the results obtained in two patient
