Background: Clinical crown lengthening by forced tooth eruption is followed by conventional surgical methods. This study aimed to determine the clinical usage of Nd:YAG laser in clinical crown lengthening by forced tooth eruption. Materials and Methods: Twenty patients who were candidates for clinical crown lengthening underwent forced tooth eruption. Inclusion criteria: a single-rooted tooth with a crown to root ratio clinically appropriate. Exclusion criteria: plaque index higher than 20%, positve bleeding on probing. Intervention: Fiberotomy with Nd:YAG laser was performed 2 days after initiation of forced tooth eruption and every 2 weeks thereafter to reach to optimum clinical crown. Primary outcome: Position of gingival margin.
