Background: The aim of this 2‐year longitudinal study was to compare the width of keratinized gingiva after orthodontic therapy for buccally erupting premolars that had been pretreated by extraction of deciduous teeth alone versus interceptive mucogingival surgery. Methods: In 8 patients (aged 9 to 12 years) who presented with bilateral buccal eruption of homologous teeth (premolars), one side was randomly treated with extraction of the deciduous molar and mucogingival surgery (test site), while the other side was treated only by extraction of the deciduous molar (control site). All of the subjects underwent orthodontic treatment with fixed appliances. Results: At the baseline visit prior to any treatment, there was no significant difference between the mean amount of keratinized gingiva at test sites (3.06 mm) and control sites (2.93 mm). Two years later, upon completion of orthodontic treatment, there was a significant difference between test (2.93 mm) and control (1.37 mm) sites in the mean width of keratinized tissue. In the control (untreated) group, 2 sites exhibited 1 mm of gingival recession after orthodontic treatment. Conclusions: Mucogingival interceptive surgery is an effective technique to maintain keratinized tissue in correspondence with buccally‐erupted teeth. J Periodontol 2000;71:182‐187.
