RESUMO
Background: Periodontal disease, characterized by inflammation and infection of the supporting structures of teeth, poses a significant oral health challenge. Traditional periodontal surgery and non-surgical therapy, such as scaling and root planing, are established treatment approaches for addressing periodontal disease. Materials and Methods: The study enrolled 120 adult patients diagnosed with moderate to severe periodontal disease. Participants were randomly allocated to one of two groups: the traditional surgery group (TSG) or the non-surgical therapy group (NSTG). In the TSG, patients underwent traditional periodontal surgery, which included flap surgery and grafts when deemed necessary. The surgical procedures were performed by experienced periodontal surgeons. In contrast, the NSTG received non-surgical therapy in the form of scaling and root planing administered by trained dental hygienists. Outcome measures encompassed clinical parameters and patient-centered outcomes. Periodontal pocket depth and clinical attachment level, both measured in millimeters, were assessed at baseline, 3 months, and 6 months. Patient-reported outcomes, including pain, discomfort, and satisfaction, were collected through standardized questionnaires at each follow-up visit. Results: Patients in the TSG experienced a notable reduction in pocket depth from a baseline of 6.8 mm to 3.7 mm at the 6-month mark, resulting in a change of -3.1 mm. Conversely, the NSTG exhibited a reduction from 6.7 mm to 4.0 mm, with a change of -2.7 mm. In the TSG, the baseline attachment level of 7.2 mm decreased to 5.1 mm at 6 months, indicating a change of -2.1 mm. In the NSTG, the attachment level decreased from 7.1 mm to 5.5 mm, resulting in a change of -1.6 mm. Patients in the TSG reported an average pain score of 3.6 on a 1-10 scale, discomfort of 4.2, and satisfaction of 7.8. In contrast, patients in the NSTG reported lower pain (2.1) and discomfort (2.9) scores but similar satisfaction levels (8.4). Conclusion: In this randomized controlled trial (RCT), both traditional periodontal surgery and non-surgical therapy demonstrated improvements in clinical parameters and patient-reported outcomes. Traditional surgery resulted in greater reductions in periodontal pocket depth and clinical attachment loss at the 6-month follow-up.
RESUMO
BACKGROUND: Shear bond analysis is the procedure used most frequently to gauge the tensile strength of adhesives incorporated in orthodontic treatments. In shear tensile strength analysis, pressure is placed as close as feasible to the interface between the orthodontic bracket and the surface of the tooth, parallel to the long axis of the tooth. Although numerous research on extracted teeth of human and bovine teeth have been conducted, there may still be variables such as pH, humidity, temperature, and others that could affect how these materials behave in the mouth cavity. The impact of chlorhexidine (CHX) on the binding capacity for non-metallic orthodontic brackets in vivo is not well understood. OBJECTIVE: The goal of the current study is to determine how mouth rinses containing 0.12% CHX affect the adhesive strength of polycarbonate orthodontic brackets. METHODS AND MATERIALS: Thirty-four patients were part of the test category, and they were instructed to wash their oral cavity for approximately 30 seconds using 20 ml of 0.12% CHX gluconate (Septodent). Thirty-four patients made up the control category and were instructed to wash their oral cavity for 30 seconds with a placebo mouthwash of a similar hue (20 ml). Both types of mouthwash were administered to the participants by an administrator who was not specifically involved in the trial and were kept in 120 ml labeled plastic bottles. The study participants were also kept unaware of the type of mouthwash. For the mouthwash utilized by study participants, a double-blinding technique was applied. RESULTS: Thirty-four patients were evaluated in the test category. Since the orthodontic bracket broke in two patients, therefore, 32 patients were evaluated in the control category. The mean value of the strength of the shear bond in the experimental category was 15.32 megapascal (Mpa). The SD value was 2.51. The mean value of the strength of the shear bond in the control subgroup was 15.63. On statistical analysis, the t-value was 0.47. The p-value was 0.671. The difference in findings of the strength of the shear bond was statistically non-significant. CONCLUSION: The results of this investigation allow us to draw the conclusion that the shear bond properties of polycarbonate orthodontic brackets are unaffected when treated with 0.12% CHX preceding the binding. The clinically meaningful adhesion strength was likewise attained by the polycarbonate orthodontic brackets.
