title: Comparison of coronally advanced and semilunar coronally repositioned flap for the treatment of gingival recession.
abstract: BACKGROUND
  Gingival Recession (GR) occurs in population with low oral hygiene levels. Root coverage may be achieved by a number of surgical techniques, including pedicle gingival grafts, free grafts, connective tissue grafts, gtr may also be used. The objective of the present study is to compare the clinical outcomes of the Semilunar Coronally Repositioned Flap (SCRF) and Coronally Advanced Flap (CAF) procedure in the treatment of miller's class I gingival recession defects in maxillary teeth.
  
  
  METHODS
  Twenty systemically healthy patients, with isolated miller's class 1 gingival recessions, were selected and allocated randomly into two groups, Group I and Group II with 10 patients in each. In Group I, the patients were treated with coronally advanced flap procedure with sling sutures, whereas in Group II, patients were treated with semilunar coronally repositioned flap without sutures.
  
  
  RESULTS
  Descriptive statistical analysis has been carried out in the present study. RESULTS on continuous measurements are presented on Mean ± SD. Significance is assessed at 5 % level of significance. Student t-test (two tailed, dependent) has been used to find the significance of study parameters between baseline - 3 months and baseline - 6 months, 90% Confidence interval for mean has been computed.
  
  
  CONCLUSIONS
  CAF provides consistently better results than SCRF With all other parameters, such as clinical attachment levels, percentage of root coverage and complete root coverage and esthetics were taken into account, caf was found to be superior. In contrary to this, there is significant increase in width of keratinized tissue in scrf group.
