Summary
BACKGROUND: The semilunar coronally repositioned flap (SLCRF) has been used for the treatment
of recession defects (GR). Recently a microsusgical (MICRO) has been successfully employed
with the procedure apparently resulting in improved results, however, no previous controlled
clinical study has evaluated the MICRO SLCRF in comparison with SLCRF performed as originally
described (MACRO). The objective of the present study was to compare the clinical outcomes of
the MICRO and MACRO SLCRF in the treatment of human GR.
METHODS: Fourteen patients, with bilateral Miller class I GR defects were randomly assigned
to MICRO or MACRO SLCRF. Clinical parameters, assessed at baseline and 6 months later,
included recession height (RECH), recession width (RECW), width of keratinized tissue (WKT),
probing depth (PD), clinical attachment level (CAL), pain measurements and esthetic
evaluation with the Root Coverage Score (RCS). Inter-measurements differences were analyzed
with a Chi-square or a paired t-test, with significance set at α<0.05.
