AIMS: This prospective case series evaluated whether hard tissue radiographic parameters influence treatment outcomes of deep mandibular gingival recessions (≥5 mm) treated with connective tissue grafts (CTG) using either a double-papilla envelope (DPE) or lateral sliding flap (LSF).
METHODS: Fifteen patients received CTG+DPE (n=7) or CTG+LSF (n=8). Clinical parameters-recession depth (RD), root coverage (RC), complete root coverage (CRC), and keratinized tissue width (KT)-were measured at baseline and 12 months. Pre-treatment CBCT scans assessed root width, mesiodistal root circumference, buccal prominence, and interproximal distance to correlate with outcomes.
RESULTS: No significant differences in clinical outcomes were found between flap designs. When data were pooled, RD significantly decreased from 6.8±1.7 mm to 0.9±0.9 mm (RC=85.8%, p<0.05), and KT increased from 0.1±0.3 mm to 3.6±1.5 mm (p<0.05). Greater baseline RD correlated with more RD reduction (p<0.05). However, none of the radiographic parameters showed significant correlation with root coverage outcomes. RT1 defects achieved 93% of root coverage while RT2 defects achieved 77.6% (p=0.06).
CONCLUSION: Within study limitations, the examined radiographic parameters did not affect outcomes. Deep mandibular gingival recessions can be effectively treated using either CTG+DPE or CTG+LSF.
