摘要:

AbstractPeriodontal surgery should eliminate disease and produce a good gingival contour to allow ease of cleaning and maintenance. An important factor in the achievement of these aims may be the contour of the attached gingiva following surgery. At present, gingival contour is evaluated by one of two indices. A new disease‐related gingival contour index was designed and compared with existing indices (plaque index, periodontal index, sulcus bleeding index) following inverse bevel flap procedures. The results demonstrated that there was a statistically significantincreasein the scores for gingival contour (p<0.001) a significantdecreasein scores for the periodontal index (p<0.001) and sulcus bleeding index (p0.7

摘要:

AbstractThis study investigated the relationship between internal and external locus of control classified patients and improvement in oral hygiene skills and plaque scores. Locus of control scores, and initial and final skill and plaque scores were recorded for 22 dental patients with moderate periodontitis. Oral hygiene instruction was given over a 3‐month period to each patient. Although patient oral hygiene skill level increased significantly and plaque scores declined significantly, no relationship was detected between the locus of control personality dimension and skill or plaque scores. It was concluded that personal oral hygiene instruction reinforced by self‐instructional manual was effective in improving oral hygiene skill and reducing plaque scores; additional strategies for future studies investigating the locus of control dimension were presen

摘要:

AbstractGingivitis was experimentally induced in 8 human subjects using an acrylic overlay to cover the teeth in the experimental area during any oral hygiene procedures. The overlays were used for a period of 3 weeks, after which the subjects received a scale and polish and then practised normal oral hygiene. At regular intervals during the experimental period, mixed saliva was collected for assay of peroxidase activity by spectrophotometric and test‐strip procedures and plaque and gingival indices were assessed clinically. A considerable increase in peroxidase activity was observed during the experimental period, which declined after normal hygiene was resumed. This procedure may allow assessment of the progression of gingivitis under experimental condition

摘要:

AbstractIn the management of chronic periodontitis, there has been a renewed interest in the local delivery of antimirobial drugs into periodontal pockets. This study assessed the effects of the acrylic strip delivery system containing chlorhexidine, metronidazole or tetracycline on subgingival microflora assessed by dark field microscopy. Strips containing 40% chlorhexidine, metronidazole or tetracycline were placed for 2 to 3 days into pockets>6 mm which bled on probing. Plaque samples were obtained before and after treatment and counts of morphological and motile groups of organisms were made by dark field microscopy. Prior to treatment, the dark field microscopic counts were similar to those previously reported for diseased sites with motile bacteria, in particular spirochaetes, present in high numbers. Following treatment, all 3 antimicrobial drugs produced a significant increase in the proportion of cocci and significant decreases in all other types of organisms. Motile organisms, in particular, were markedly reduced and spirochaetes could not be recovered from some sites treated with metronidazole and tetracycline. Metronidazole was significantly more effective than tetracycline or chlorhexidine on spirochaetes. The results indicate that acrylic strips may be useful in the management of chronic periodontitis as an adjunct to routine mechanical methods.

摘要:

AbstractThe purpose of the study was to examine the relationship between spacing and dental health in 15‐year‐old adolecents. The whole sample consisted of 156 subjects. Out of them, 74 females and 73 males with 6 anterior teeth made up the study group for examination of the upper jaw. 75 females and 75 males had 6 anterior teeth in the lower jaw and made up the study group for examination of the lower jaw. The Plaque Index (PII) and the Gingival Index (GI) were recorded. Probing depths (PD) were measured as explained by Glavind&Løe. Filled surfaces (FS) were taken from the individual ease sheets and controlled clinically. The spacing of the individuals was assessed by counting the number of proximal surfaces without visible contact with the adjacent proximal surfaces, on model casts. The sum of proximal surfaces without contact made up the Space Index (SpI) of the individual jaw. Parametric and non‐parametric statistical methods were used to analyze the data. In both sexes and both jaws proximal surfaces without interdental contact had a more favourable periodontal condition than surfaces with contact. In the upper jaw of both sexes, proximal surfaces without interdental contact had a reduced number of filled surfaces compared to surfaces with contact. The linear relationship between SpI and FS was significant, i.e., an increased number of surfaces without contact was accompanied by a reduced number of filled surfaces. In the lower jaw, the differences between the SpI groups and the linear relationship between SpI and FS did not reach significance. In both sexes and both jaws, proximal surfaces without fillings had a more favourable periodontal state compared to surfaces with fillings. Indications are that the summation effect of the presence of interdental contact and the presence of fillings contributed to the differences in periodontal condition between surfaces with and without interdental c

摘要:

AbstractThe present investigation was performed to study the effect on localized juvenile periodontitis (LJP) of a treatment program which included tetracycline administration, surgical elimination of inflamed tissues, scaling and root planing, and careful plaque control during healing. Treatment of LJP lesions was carried out on 16 individuals aged 14 to 18 years (JP group). Lesions in first molars and incisors in a group of patients with adult periodontal disease (AP) were treated in an identical manner and served as controls. The presence of angular bony defects adjacent to first molars and incisors was first documented in all patients. Thereafter, a clinical examination was carried out, including assessments of oral hygiene status, gingival conditions, probing depths and attachment levels. The patients were subjected to a treatment program involving administration of tetracycline (250 mg 4 times per day for 2 weeks), removal of granulation tissue after flap elevation, and root curettage. After surgery, the patients were instructed to rinse the mouth with 0.2% chlorhexidine for 2min twice a day during the first 2 postsurgical weeks. Professional tooth cleaning was carried out once every 3 months during a 5‐year period. At 6, 12, 24 and 60 months after surgical treatment, the patients were re‐examined regarding oral hygiene, gingival conditions, probing depths and attachment levels. Treatment of LJP lesions resulted in resolution of gingival inflammation, gain of clinical attachment, and refill of bone in angular bony defects. The healing of the lesions of this patient sample was similar to healing observed in patients with

摘要:

AbstractThe influence of differences in imaging geometry on the detection of small periodontal bone lesions was studied when using a digital subtraction technique. The results were compared with those from conventional radiographs. Reference radiographs were obtained on human mandibular jaws before small lesions were made in the marginal alveolar bone. Subsequent radiographs were taken with the same imaging projection as well as with changes of the angulation in cither vertical, or horizontal direction, or both.10 dentists served as observers, who compared the conventional radiographs taken before and after the lesions were made, and registered the presence or absence of lesions using a diagnostic rating scale. The conventional radiographs were digitized, and subtraction images made. These images were interpreted by the same observers. For each observer, image modality and projection, the resulting rates of true positive and false positive diagnoses were plotted on a graph. The area under the curve, obtained by connecting the paired values of true positive and false positive results associated with the different diagnostic ratings, was used as a measure of diagnostic accuracy. Statistically significant differences could be demonstrated between the results obtained from the subtraction images, whether produced from identical or non‐identical pairs of conventional radiographs, and the results from the conventional radiographs obtained under ideal condition
