    Notes: Abstract 11 adult patients with moderate to advanced periodontitis were treated with oral hygiene instruction and an initial, single episode of root debridement. Before therapy, 3 independent clinicians examined all patients and identified sites that in their opinion probably would not respond to the therapy and would continue to lose attachment. On 2 occasions, 3 and 12 months later, the clinicians reexamined and reevaluated all patients and all sites. The results of therapy were also monitored by probing attachment level measurements performed every 3rd month. All 11 patients completed 24 months of follow-up, and 6 subjects were available until 36 months. Sites with probing attachment loss after 12, 24 and 36 months were identified using linear regression analysis and compared to the clinicians' prediction of probing attachment loss. The results demonstrated a limited agreement between probing attachment loss determined by linear regression and the clinicians' predictions of probing attachment loss. It appears that the traditional clinical signs and factors used to forecast and identify periodontal disease activity are only moderately associated with probing attachment loss. This suggests that attachment loss may be caused by several factors, at least following initial therapy. The progression of an inflammatory disease of microbial etiology may be only 1 of such causes. Further studies are needed to clarify the nature and cause of probing attachment loss.

    Notes: Abstract The aim of this study was to determine whether changes in probing attachment levels are related to subgingival spirochete or leukocyte counts in periodontal pockets. Following initial clinical recordings and therapy consisting of oral hygiene instruction and root debridement, the probing attachment levels of proximal sites of 120 single-rooted teeth in 7 patients were measured every 3 months for 12 months. The measurements of each site were subjected to regression analysis, which determined whether the site was deteriorating, improving, or non-changing. Subgingival washings were taken of 19 deteriorating, 22 improving, and 127 non-changing sites to determine the number and % of spirochetes and the number of leukocytes at each site. Improved probing attachment levels were associated with reduced numbers of spirochetes and leukocytes. However, the ranges of individual measurements of subgingival washing variables overlapped considerably between groups. Spirochete and leukocyte counts related better to the 12-month probing depths than to changes in probing attachment levels during the preceding 12 months. These findings suggest that none of the tested subgingival washing parameters are suitable indicators of changes in attachment levels on an individual site basis.

    Notes: Abstract The removal of interproximal plaque was compared using a standard toothbrush alone, a toothbrush with unwaxed dental floss and a toothbrush with an interdental brush. 30 previously treated periodontal patients were given the cleaning aids in a three-way crossover study design. After each 1 month trial period, scores for gingivitis, buccal/lingual plaque and proximal plaque were recorded. Mean GI scores for subjects were 0.37 using the toothbrush only, 0.36 using the toothbrush with floss and 0.32 using the toothbrush with the interdental brush. Mean buccal/lingual plaque scores were 0.64 using the toothbrush only, 0.62 using the toothbrush with floss and 0.51 using the toothbrush with the interdental brush. Mean proximal plaque scores were 2.32 with the toothbrush only, 1.71 using the toothbrush with floss and 1.22 using the toothbrush with the interdental brush. Statistically significant differences were seen in proximal plaque scores between the 3 treatment groups. The results indicate that the interdental brush used in combination with a toothbrush is more effective in the removal of plaque from proximal tooth surfaces than a toothbrush used alone or in combination with dental floss.

    Notes: Abstract 19 adult periodontitis patients were treated with plaque control and a single episode of root debridement. Results of this treatment were monitored in non-molar sites, molar flat surface sites, and molar furcation sites by probing attachment level measurements every 3rd month for 24 months. After 24 months, sites with probing attachment loss were identified using linear regression analysis. Clinical scores for supragingival plaque, bleeding on probing, suppuration on probing, and probing depth, obtained from these sites during the 24-month study, were analyzed to determine if they could be used diagnostically as indicators of probing attachment loss. The results demonstrated that the diagnostic accuracy for these clinical indicators was generally low at all 3 anatomical site locations. A possible explanation for this limited diagnostic accuracy may be that some areas of probing attachment loss following basic periodontal therapy are caused by factors other than the progression of an inflammatory periodontal disease of microbial etiology.

    Notes: Abstract Recordings of supragingival plaque, bleeding, suppuration and probing depth were obtained for 42 months following initial periodontal therapy. Scores accumulated after various time intervals during monitoring were studied for their predictive value in revealing probing attachment loss as determined by regression analysis during the 0–42 month period. Accumulated plaque scores demonstrated low predictability. Accumulated bleeding scores showed modest predictive values. Suppuration on probing was not a frequent finding during the observation interval and also had modest predictive power. Increase in probing depth compared to baseline and deep residual probing depth had modest predictability after 3 and 12 months, but showed increasing accuracy in revealing probing attachment loss over later time intervals. After a few years of maintenance, increase in probing depth, particularly if combined with high frequency of bleeding on probing, showed the highest predictive value for probing attachment loss of the scores examined.

    Notes: Abstract The healing response of non-molar sites, molar flat surface sites, and molar furcation sites was investigated in 19 adult periodontitis patients following a periodontal therapy of plaque control and root debridement. A total of 2472 sites were monitored by recordings of dental plaque, bleeding on probing, probing depth, and probing attachment levels every 3rd month for 24 months. The results demonstrated that in sites with initial probing depth of 4.0 mm or greater, molar furcation sites responded less favorably to the therapy as compared to molar flat surface sites or non-molar sites. This was demonstrated by higher mean scores for bleeding on probing, less reduction in probing depth, and a mean loss of probing attachment of 0.5 mm over 24 months. Site analyses using linear regression showed a higher % of deeper sites with probing attachment loss for the molar furcations than either molar flat surface or non-molar sites. Among sites initially 7.0 mm or deeper, 21% of molar furcations were identified as showing probing attachment loss as compared to 7% of the molar flat surface sites and 11 % of the non-molar sites.

    Notes: Abstract 10 adult patients with periodontitis were treated with oral hygiene instruction and a single episode of supra- and subgingival debridement using either a sonic or an ultrasonic instrument in a split-mouth design. The clinical response was evaluated by measurements of dental plaque, bleeding on probing, probing depths, and probing attachment levels taken at baseline and every 3rd month for 12 months. An improvement of periodontal conditions was observed during the initial 3–6 month period followed by a stabilization of parameters. No difference in clinical response could be observed between sites treated with the sonic or ultrasonic instruments.

    Notes: Abstract 64 sites with probing pocket depth 〈inlineGraphic alt="geqslant R: gt-or-equal, slanted" extraInfo="nonStandardEntity" href="urn:x-wiley:03036979:JCPE568:ges" location="ges.gif"/〉6 mm from 11 patients were treated with plaque control instruction and one episode of root planing. Subsequently, selected sites in each patient were irrigated with either chlorhexidine, tetracycline, saline or served as non-irrigated control sites. Irrigation immediately followed instrumentation, and was repealed every 2 weeks for 24 weeks. Healing was monitored at 8, 16, and 24 weeks clinically and at 7, 15, and 23 weeks with subgingival washings for determination of % as well as total number of spirochetes.The following changes were apparent from comparing pooled site means al 24 weeks with pre-treatment data: (1) bleeding sites decreased from 62 of 64 sites initially to 22 of 64 at 24 weeks; (2) spirochetes decreased from 34% to 2%; (3) probing pocket depths decreased from 7.6 to 4.7 mm; (4) probing attachment levels showed a gain of 1.2 mm. The improvement of the chlorhexidine and tetracycline irrigated sites was similar to that of the saltne irrigated and non-irrigated control sites.Thus, biweekly chlorhexidine, tetracycline or saline irrigation of deep pockets did not appear to augment the effects of non-surgical periodontal therapy.

    Notes: Abstract The healing events of 7 patients with generalized chronic periodontitis were monitored clinically during 3 consecutive phases of treatment: 1) tooth brushing and flossing, 2) subgingival use of the Perio-Aid®, and 3) supra and subgingival instrumentation. The clinical parameters evaluated were plaque score, bleeding score, probing pocket depth, probing attachment level, and gmgival recession. Each phase continued until maximum effects were achieved (5,3, and 9 months respectively) determined by minimal or no changes in bleeding scores and probing pocket depths between 3 successive examinations. The results showed limited improvement in the bleeding scores and probing pocket depths with tooth brushing and flossing only (Phase 1). During use of the Perio-Aid (Phase2), there was no additional improvement, but the initial limited gains made during Phase 1 were maintained. By the end of Phase 2, however, a slight loss of probing attachment level was noticeable. After instrumentation (Phase 3), there was further and more pronounced improvement in bleeding scores and probing pocket depths, as well as a reversal of the probing attachment loss. The results of this study indicate that significant improvement in periodontal pockets should not be expected following home care procedures alone, and that instrumentation may account for the bulk of improvement seen following a combined therapy of plaque control and instrumentation.

    Notes: Through-and-through furcation defects were experimentally created in one group of monkeys (Study 1) and in one group of dogs (Study 2). The effect of reconstructive periodontal surgery using citric acid conditioning of the instrumented root surfaces was studied. Two experimental variables were investigated: (1) variation of the placement and suturing of the flaps and (2) variation of the size of the furcation defects.The results of these studies indicate that adequate postoperative flap coverage of the furcations seems to be critical for successful healing of the furcation defects. Variations in the vertical dimension of the defects seems to play a secondary role. Future studies in experimental animals should evaluate methods which will provide improved post-operative coverage of the furcation area during healing of furcation defects in human patients.
