    Notes: Objectives: The purpose of the present paper is to review available information on the treatment of peri-implant mucositis and peri-implantitis.Materials and Methods: The results of animal research and human studies are presented. Proposed strategies for the treatment of peri-implantitis presented in the literature are also included.Results: Most of the information accessible at this time derives from case reports. The reports provide evidence that efforts to reduce the submucosal infection may result in short-term improvements of the peri-implant lesion. They also indicate that regenerative procedures in intrabony peri-implant defects can result in the formation of new bone.Conclusions: Several uncertainties remain regarding the treatment of peri-implantitis. Properly conducted long-term follow-ups of consecutively treated cases would seem to be a realistic avenue for accumulation of more information. This may assist in establishing the predictability, magnitude and stability of improvements that can be achieved.

    Notes: Abstract This study was designed to histologically determine the relationship of the periodontal probe tip to the periodontal tissues during probing of untreated periodontal pockets and periodontal pockets treated with oral hygiene and root planing. Human, condemned, single rooted teeth with buccal probing pocket depth at least 6 mm were used. Two groups of specimens were included: 12 untreated teeth from six patients and 15 treated teeth from 10 patients.In the treated group, the effects of therapy were monitored clinically every 2 weeks until maximum improvement had taken place. A periodontal probe tip was then inserted on the buccal aspect of the tooth using 0.50 N pressure, and block section biopsies were taken. The histologic examination of the untreated teeth showed that the probe tip penetrated beyond the apical termination of the functional epithelium and into the subjacent connective tissue by a mean of 0.45 ±0.34 mm, whereas in the treated specimens the probe stopped coronally to this landmark by a mean of 0.73±0.80 mm.This study demonstrated that the probe tip most often does not reach the base of the junctional epithelium in pockets treated by plaque control and root planing, and that clinical measurements of attachment levels are not reliable in determining the true histologic level of connective tissue attachment.

    Notes: Abstract. Sixteen dental, dental hygiene, and dental assisting students and dental faculty members who had contralateral or unilateral areas of minimal (≤ 1.0 mm) and appreciable (≥ 2.0 mm) widths of keratinized gingiva on mid-buccal plaque-free surfaces of mandibular bicuspids were examined. Gingival exudate amounts and clinical inflammation based on color change and/or swelling and bleeding on probing were evaluated. The result showed that gingiva with “appreciable” width as well as gingiva with “minimal” width of keratinized tissue exhibited only minute amounts of gingival exudate. Also, there were generally no clinical signs of inflammation for both types of tissue.From the groups of 16, six subjects were selected who had contralateral pairs of minimal and appreciable keratinized gingiva. They were instructed to cease oral hygiene in the lower bicuspid area for 25 days. At day 0, 4, 7, 11, 14, 18, 21, and 25, plaque, gingival exudate, and clinical gingival inflammation were evaluated. Results revealed increases in plaque, gingival exudate scores and clinical gingival inflammation over the 25-day period with no apparent difference between the areas with minimal and appreciable width of keratinized gingiva.

    Notes: Abstract 2 main concepts seem to exist for the progression of periodontitis: (1) a slow continuous process of attachment loss; (2) periodic bursts of activity followed by quiescence or remission. This study addresses this problem and presents data for 69 sites having experienced a net loss of probing attachment amounting to ≥3.0 mm over 42 months. The sites originated from 16 adult patients monitored after nonsurgical treatment of advanced chronic periodontitis. Probing attachment level recordings were obtained every 3rd month. The sequential probing attachment level data for each site were smoothed using cubic splines. Subjective evaluation of the raw and the smoothed data from the study sites suggested that the majority of the sites seemed to lose probing attachment in a continuous fashion, and over periods of 12 months or more. The smoothed curves were subjected to principal components analysis, which allowed the 69 sites to be ordered according to curve similarity. Nonparametric runs test failed to show that the shape of the curves for the sites was significantly associated with any of the following characteristics: patient, tooth type, tooth surface, initial probing depth, bleeding frequency, occurrence of suppuration, or a combination of inflammatory characteristics of sites.

    Notes: Abstract Two plaque control programs were compared. One of the programs was given as a series of three consecutive 30-min instruction appointments during a 14-day period. The other program was condensed into one 15-min instruction appointment and two subsequent 15-min follow-up visits. Fifty-nine blue-collar workers served as subjects and were divided into three matched groups: two experimental groups (30-min and 15-min group) and one control group.The 30-min program as well as the 15-min program significantly reduced the plaque scores in the participants. No difference could be observed between the results of the two programs during the immediate 12-week observation interval or throughout the subsequent 24 months of maintenance care. The results of the present study together with results by Söderholm et al. (1980) and Woofter et al. (1980) indicate that comprehensive plaque control programs may not be necessary and may not increase the effect of basic plaque control instruction.

    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 Previous studies indicate that root resorption is a frequent sequela to significant amounts of periodontal repair in animal models. A model was developed in tabrador dogs to study periodontal wound healing in large circumferential defects in the absence of influence from the oral environment. A polytetrafluore-thylene membrane of 1 μm pore size (GORE-TEX®) was used to occlude cells from specific tissues from populating the healing den tin-connective tissue wound. 3 modalities were studied: (1) control, in which no membrane and therefore no cell occlusion was used, (2) flap occlusion, in which the internal surface of the flap was lined with the membrane preventing contribution of cells from the flap, (3) bone occlusion, in which the reduced alveolar bone was lined with the membrane preventing contribution from bone cells. Wound closure included total submergence of teeth and membranes. The membranes remained incorporated and no exposure of membranes or teeth occurred during the 3 months healing period. Histology revealed bone regrowth in all 3 treatment modalities. It is suggested that inductive elements in the connective tissue or dentin, or bone cells from periosteum were responsible for bone regrowth in the bone membrane treatment modality. No significant difference was seen for root resorption between the 3 treatment modalities. This study found that physical occlusion of cells from the inside of the surgical flap, or from the pre-existing bone, is not sufficient to prevent root resorption in periodontal wound healing.
