Clinical Trial Randomized Controlled Trial
The efficacy of a topical anesthetic on pain and unpleasantness provoked by scaling of gingival pockets was investigated in 20 patients with mild chronic periodontitis. A eutectic mixture of local anesthetics (EMLA) and a placebo cream, both occluded by Orahesive Oral Bandages, were applied in a balanced, randomized, double-blind, split-mouth design, which enabled within-subject comparison of the anesthetic and the placebo in the upper and the lower jaw. Pretreatment interviews showed that approximately two-thirds of the patients considered gingival scaling to be associated with some degree of pain and unpleasantness. Pain intensity and unpleasantness were evaluated on 100-mm visual analog scales (VAS). Application of EMLA reduced both pain intensity and unpleasantness significantly compared to placebo cream. Median reductions in VAS pain intensity in the upper and lower jaw were 58.9% and 61.9%, and corresponding reductions in VAS unpleasantness were 31.9% and 25.6%, respectively. Generally, the patients accepted the anesthetic procedure well. The residual perception of pain and unpleasantness following topical anesthesia may be dependent on activation of nonanesthetized nociceptive fibers in the tooth pulp. However, the present study clearly demonstrates the efficacy of a topical anesthetic in a clinical situation, which may be recommended as a simple pharmacologic strategy to reduce pain and unpleasantness during scaling procedures.

Comparative Study
The clinical effects of a periodontal dressing after modified Widman flap surgery were studied. A total of thirty surgical sites in 13 patients were included in the study. Half of the sites were not covered by a periodontal dressing while the other half were. To effect a blind evaluation, the dressings were placed and removed by someone other than the examiner. Gingival crevicular fluid flow and gingival inflammation were measured prior to surgery, 2 weeks, 1 month and 2 months after surgery. Clinical attachment level and pocket depth were measured prior to surgery, 1 month and 2 months after surgery. All patients were instructed in oral hygiene procedures and received rubber cup prophylaxes and flossing at 1 week, 2 weeks, 1 month and 2 months postoperatively. At the conclusion of the study, a questionnaire was administered to each patient. No significant differences were found between dressed and undressed segments regarding changes in clinical attachment levels, pocket depth, or gingival inflammation. The omission of a dressing did not result in a greater incidence of discomfort. More patients stated preference for no dressing.

Comparative Study
The effects of three periodontal dressings (Coe-Pak, PPC, Perio Putty) upon subcutaneous tissues in 26 Sprague-Dawley rats were investigated. The three dressings, and a control (Teflon), were placed into polyethylene tubes. Two tubes per animal were implanted on either side of the dorsal midline area. After 14 days the specimens were retrieved and prepared for histological examination. Three methods of scoring were utilized for evaluation. First, a system evaluating the overall number of inflammatory cells, connective tissue capsule thickness, and the vascular changes produced; second, an inflammatory cell count, the Inflammatory Index (I.I), computing the inflammatory cells in a particular field of view for each material; and third, a Reaction Spread Index (R.S.I.) comparing the distance of the spread of the inflammatory reaction into the connective tissues. Statistical analysis of the data was carried out utilizing the Chi-square test and analysis of variance. While the three scoring systems utilized did result in some comparative variation in reactions, the overall order of decreasing severity was always PPC, Coe-Pak, Perio Putty, and Teflon.
