摘要:

AbstractA case report of the clinically successful management of an intrabony pocket associated with a periodontal abscess of a lone‐standing, functioning mandibular canine utilizing an autogenous, intraoral site cortical and cancellous bone graft concurrently with a lateral pedicle soft tissue graft is presented. The rationale for the diagnostic, prognostic and therapeutic considerations is discussed in light of the experimental and observational knowledge gained from the literature to dat

摘要:

AbstractFour clinical methods to evaluate healing after reconstructive therapy of intraosseous periodontal defects were compared: 1. probing attachment level, 2. probing bone level, 3. entry/re‐entry bone height measurements, 4, radiographic bone height determinations. Thirteen patients with a total of 33 defects volunteered for the study.It was found that the depth of the lesions recorded by the various methods showed differences which seem to relate to the varying nature of the methods, On the average, the periodontal probe penetrated 0.8 mm deeper during probing for bone level than during probing for attachment level and another O.3mm deeper after denudation of the lesions during entry/re‐entry. The average‐ gain of periodontal support following treatment was approximately 1.4mm as recorded by probing attachment level, probing bone level and entry/re‐entry bone height determinations, respectively. A high degree of correlation was found between all three probing methods when the changes following therapy for the individual sites were compared (r = 0.8 5, 0.75 and 0.81, respectively), Radiographic bone height showed lower degrees of correlation with all three probing parameters (r = 0.45, 0.46 and 0,47, respec

摘要:

AbstractThe present investigation was undertaken (1) to analyze the prevalence of root surface caries prior to and after periodontal treatment and (2) to determine the feasibility of using simple clinical criteria for predicting a patient's risk of developing root surface canes following periodontal therapy.Thirty‐one patients were given advanced periodontal treatment including periodontal surgery. At baseline they were examined for oral hygiene status, periodontal status, root surface canes experience and number of lactobacilli per ml saliva as evaluated by the Dentocult® dip‐slide method. Follow‐up examinations 1, 2 and 4 years after baseline showed that a majority of the patients were treated successfully and maintained in periodontal health. Root surface caries developed in approximately two‐thirds of the patients during the 4–year observation period. However, the total increment of root lesions during these years was mostly extremely low. i.e. less than 5% of exposed root surfaces.In higher risk patients developing new root surface caries, significant correlations were demonstrated with initial pretreatment scorings for (1) their previous root surface caries experience, (2) high lactobacillus counts and (3) advancing age. In addition, root surface caries incidence and low saliva secretion rates were found to correlate significantly during the course of

摘要:

AbstractForty‐three patients with severe periodontal destruction were treated by a modified flap operation and their periodontal condition reassessed about 4 years later. The aim of the study was to see what would happen to the periodontium when the responsibility for oral hygiene was left to the patients themselves. Before the operation the importance of plaque in the etiology of periodontal disease was explained to the patients. They were requested to return for reexamination every 6 months, but no recall system was used.A highly significant reduction in the depth of the gingival pockets was achieved and the average loss of bony support during the observation time was only 0.3 mm.However, an increased bleeding index, loss of marginal bone and deepening of the gingival pockets were found around teeth provided with artificial crowns, especially when the crowns had ill‐fitting margins extending into the gingival poc

摘要:

AbstractThe objective of this study was to compare tooth mobility following two methods of eliminating nonworking side interference (NWSI). The first method involved the complete elimination of any tooth contact on the NWS. The second method involved the reduction of the NWSI to a level which was harmonious with the occlusion on the working side.Thirty‐three clinically healthy individuals having nonworking side interferences and no pathological signs of occlusal trauma, participated in the study. After 1 month of intensive training in oral hygiene, the volunteers were divided into three groups of 11 each. The first two groups were experimental and the third group received no occlusal adjustment to serve as a control.In the first group tooth mobility measurements and periapical x‐ray films of teeth with nonworking interferences were taken. Occlusal interferences were then totally eliminated by selective tooth grinding. Two months later mobility and x‐ray recordings of same teeth were repeated. In the second group the same procedure was performed, but nonworking side interferences were adjusted to harmonious contacts with occlusion on the working side. Tooth mobility was measured in hundredths of a millimeter, using the microperiodontometer designed by Mühlemann (1954). Data were subjected to statistical analysis and the following conclusions were drawn:1Tooth mobility was significantly (P<0.001) reduced after complete elimination of nonworking side interferences, as well as after adjusting the nonworking side interferences to harmonious contacts with occlusion on the working side (P<0.01).2The reduction in mobility was significantly (P<0.001) greater when occlusal interferences were completely eliminated than when harmonious contacts were achieved.3There were no detectable radiographic changes, either in the interproximal alveolar bone level or periodontal ligament spaces, 2 months following occlusal adju

摘要:

AbstractThis study investigates the possible use of unstandardized bite‐wing radiographs to determine the rate of alveolar bone loss over long periods of lime. A total of 100 pairs of bite‐wing radiographs obtained from patients of two general dental practitioners were read on a 3M Reader, normally used for reading microfilm. For the purpose of measurement, two reference points were selected on the teeth; the highest point on the occlusal surface of the crown, the mesial and distal points of the cemento‐enamel junction. Both vertical and horizontal bone loss was measured. Initially bone levels on 20 full mouth bite‐wing radiographs on all posterior teeth were measured, then in the next 80 cases, an abbreviated index was used. The bone heights were first examined at the beginning and then at the end of a 10–year time span. The percentages of measurable distances were 28% and 57%. From the Occlusal measurement point and the C E J measurement points, reasons for unreadability were also recorded. The annual rate of horizontal boneless was 0.06 mm and 0.04 mm from the Occlusal reference point and the CEJ reference point. The rates for the vertical bone loss were 0.05 and 0.03 mm. In order to study whether there was a constant loss over a period of time, bone levels were measured for 10 successive years. The findings suggest that the bone loss rate per year fluctuated. The study suggests that the bite‐wing radiographs can be used in longitudinal studies of periodontal disease and can provide important information on the natural history of
