The ultimate goal of periodontal therapy is the regeneration of periodontal tissue which has been lost due to destructive periodontal disease. Various periodontal procedures have been used throughout the years in an attempt to reestablish attachment of periodontal tissues to root surfaces affected by periodontitis. Flap debridement surgery has been demonstrated to be a successful procedure in gaining the probing attachment level and reducing probing depth. A tendency towards impaired wound healing following periodontal procedures in smokers has been clinically documented. But, previous clinical studies on healing response in smokers are based on a retrospective design. The purpose of this study was to evaluate the treatment outcome following flap debridement surgery in smokers compared to nonsmokers. 25 patients with moderate to advanced periodontitis were included for study. Among these patients, 13 patients were smokers, and 12 patients were nonsmokers. Mucoperiosteal flap was raised with the sulcular incision. No antibiotic treatment was administered postsurgery. The patients was recalled at monthly intervals during a period of 6 months following the surgery. The patients were received supragingival scaling and oral hygiene reinforcement. All the recordings, including modified O' Leary plaque control record, bleeding on probing, probing pocket depth, probing attachment level,were recorded, presurgery and 6 months postsurgery. The changes of all the recordings at 6 months after flap debridement surgery revealed the following results: 1. PI on all the dentitions and surgical sites showed no statistical significance between smokers and nonsmokers at presurgery. But, smokers demonstrated a significantly lower % of PI than nonsmokers at 6 months postsurgery. 2. Smokers demonstrated a greater % of BOP sites than nonsmokers on the surgical sites and all the dentitions, presurgery and 6 months postsurgery. But, there was no statistical significance between two groups. 3. Smokers exhibited significantly less reduction of probing depth in the 3 mm or less probing pocket depth(PPD) group, 6mm or more PPD group and total PPD group when compared to nonsmokers at 6 months postsurgery. 4. Smokers exhibited significantly less gain of probing attachment level(PAL) in the 3mm or less PPD group, 6 mm or more PPD group and total PPD group when compared to nonsmokers at 6 months postsurgery.

Purpose: To evaluate the results from arthroscopic repair versus debridement for full-thickness tears of the upper subscapularis tendon. Materials and Methods: Ninety-nine patient outcomes were evaluated and compared prospectively. Sixty-nine patients with full-thickness tears of the upper subscapularis tendon underwent arthroscopic repair (group I) and thirty patients underwent simple debridement (group II) between May 2003 and October 2007. In all patients, the tear was localized to the superior one third of the upper subscapularis tendon. The results of the treatment were assessed by evaluating the UCLA, ASES, and VAS for pain and internal rotation strength scores before and after the operation. Results: In groups I and II, UCLA, ASES, VAS, and internal rotation muscle power (perfect score = 5) scores were improved after surgery. In comparing group I and group II, the UCLA and VAS scores were not significantly different (p>0.05), while the ASES and internal rotation strength scores were significantly different (p<0.05). Conclusion: The arthroscopic repair of full-thickness tears of the upper subscapularis tendon was a better surgical method than simple debridement.

Purpose: This study evaluated the clinical outcomes of debridement arthroplasty using the posteromedial approach in elbow joints with pain and bony limitation of motion. Materials and Methods: This study involved 16 elbows in 16 patients with pain and bony limitation of motion, which were treated by debridement arthroplasty using the posteromedial approach from March 2005 to March 2008. The mean follow up period was 27.6 (13~52) months. The clinical outcomes were analyzed using the Visual Analogue Scale(VAS) for pain scale, the preoperative and postoperative range of motion and the Mayo Elbow Performance Scores(MEPS). Results: The VAS was decreased significantly from a preoperative mean of 4.5 to a postoperative mean 1.1 (p<0.001). The average arc of motion improved significantly from $61.6 (0~90)^{\circ}$ preoperatively to $109.4 (80-120)^{\circ}$ postoperatively (p<0.001). The MEPS also improved significantly from 59.4 to 85.6 postoperatively (p<0.001). There were no complications, such as hematoma and elbow instability. Conclusion: Debridement arthroplasty using the posteromedial approach is a useful surgical procedure in the elbow joint with pain and bony limitation of motion, where all compartments can be debrided, the ulnar nerve can be manipulated easily and damage to the medial collateral ligament can be minimized.

Medially retracted large-sized rotator cuff tears includes large-sized tears, massive tears and irreparable tears. Generally arthroscopic repair or open repair of rotator cuff tears is used in reparable tears. However, arthroscopic repair requires long period practice and endurance. In irreparable tears, arthroscopic debridement, partial repair, latissimus dorsi transfer and retrograde arthroplasty can be the option. Arthoscopic debridement gives temporal relief who experienced improvement in pain and increase in range of motion after subacromial local anesthetic injection. Also arthroscopic partial repair gives good results in irreparable cases, especially in suprascapular nerve traction neurapraxia. Tendon transfer can be used in mild to moderate muscle weakness in shoulder abduction for long term treatment. Pectoralis major transfer can be used in anterosupeior tears and latissimus dorsi transfer can be used in posterosuperior tears. Reverse shoulder prosthesis is used in extreamly weakened shoulder pseudoparalysis. The authors discussed the method of arthroscopic repair in irreparable tears. The debridement, partial repair, and tendon transfer could be used in medially retracted large-sized rotator cuff tears.

Peri-implantitis is defined as an inflammatory process affecting the tissues around an osseointegrated implant, resulting in the loss of the supporting bone. Microbial adherence and colonization appear to play a major role in the pathogenesis of periimplantitis. The decision regarding treatment strategies is based on the diagnosis. The severity of the peri-implant lesion and the treatment strategies must include mechanical cleaning (infection control) procedures. Mechanical instrumentation is widely used for the debridement of dental implants, but this may alter the titanium's surface properties. Therefore, selection of the type of instrumentation should be made depending on the type of surface to be debrided. Also, patients with dental implants must always be enrolled in a supportive therapy program.
