TITLE:
"Comparative Evaluation Of the Restorative Capacity Of Marginal Gingiva Using Minimal Invasive Non-Surgical Periodontal Therapy and Conventional Subgingival Instrumentation Involving RT1 Gingival Recession : A Randomized controlled clinical trial."
RATIONALE:
Gingival recession is a common condition and its extent and prevalence increase with age. Majority of patients probably present with localized and shallow gingival recession that need a specific treatment because they are susceptible to further apical displacement of gingival margin. So if gingival recession is detected early, removal of causative factors and non surgical treatment initiated then it can prevent more advanced mucogingival defects. Studies have shown that non surgical periodontal therapy including proper oral hygiene instructions, periodic scaling and root planning obtained successful root coverage in shallow gingival recession. Minimal invasive non surgical periodontal therapy (MINST)uses the delicate instruments and magnifying loupes performing periodontal debridement with more effective calculus and biofilm removal and less soft tissue trauma , maintain the tissue architecture, benefit the healing phase, improve the clinical results and increase visibility. There is no study to evaluate efficacy of MINST versus conventional subgingival instrumentation in the restorative capacity of marginal gingival in RT1 gingival recession , so the present study will evaluate the same.
AIM:
To compare and evaluate the efficacy of minimal invasive non surgical periodontal therapy (MINST) and conventional subgingival instrumentation in the restorative capacity of marginal gingiva involving RT1 gingival recession.
OBJECTIVES:
PRIMARY OBJECTIVE
1. Comparative evaluation of improvement in recession depth, recession width and root coverage percentage after using Conventional Subgingival Instrumentation.
2. Comparative evaluation of improvement in recession depth, recession width and root coverage percentage after using MINST.
SECONDARY OBJECTIVE To assess the improvement in other clinical parameters which include- Clinical attachment level (CAL), Probing Pocket Depth (PPD), Bleeding on probing (BOP), Plaque index (PI), Gingival index (GI),Gingival thickness (GT), Keratinized tissue width (KTW) and Visual analog scale for patient reported outcome of pain and hypersensitivity.
SETTING:
Department of Periodontics and Oral Implantology, PGIDS, Rohtak, Haryana.
STUDY DESIGN:
Randomized controlled clinical trial
TIME FRAME:
12-14 months
POPULATION:
Systemically healthy patients with RT1 gingival recession will be recruited in the study from out patient department of Periodontology. Recruitment of the patients for the study will be based on eligibility criteria after obtaining informed and written consent.
MATERIAL AND METHOD:
Systemically healthy patients having RT1 gingival recession will be assigned into control group (Conventional subgingival instrumentation) and test group( MINST). One group will be treated with Conventional subgingival instrumentation and other group will be treated with MINST. All the patients will be recalled twice in 1st and 2nd month followed by 3 months and 6 months for reevaluation. Standardized oral hygiene instructions will be imparted and reinforced at each appointment. Minimal Invasive non surgical periodontal therapy(MINST) and conventional subgingival instrumentation will be performed at follow up visits if required.
STATISTICAL ANALYSIS:
Data recorded will be processed by standard statistical analysis. The normality of distribution of data will be examined by Shapiro Wilk test. Statistical analysis will be performed according to distribution of data. If it is in normal distribution, inter group comparison will be done by using Independent T test and paired T test will be use for intragroup comparison and if non normal distribution of data, inter group comparison will be done by Mann-whitney U test and intragroup by signed rank test . The Chi square test will be applied to analyze categoric data. Correlation and association between predictors and dependent variables will be analyzed by correlation analysis and regression analysis.
RESEARCH QUESTION:
Does the use of minimal invasive non surgical periodontal therapy enhances the restorative capacity of marginal gingiva of RT1 gingival recession than conventional subgingival instrumentation.
