    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 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 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.
