[Comparison of clinical and radiological features of keratinized gingiva and buccal cortical bone in patient with gingival recession].

Compare clinical and radiological features of keratinized gingiva and buccal cortical bone of identical corresponding contralateral teeth with recession (recession group) or without recession (control group). A total of 60 teeth from 27 patient were observed. The thickness of gingiva was significant reduced in recession group (0.85 mm, range 0.7-0.95 mm) that in control group (0,95 mm, range 0.8-1.0 mm), p<0.05. In recession and control group the height of keratinized gingiva was 1.58 mm (range 0.9-1.9 mm) and 3.0 mm (range 2-3.4 mm), correspondingly (p<0,05). The mean distance from cementoenamel junction to buccal cortical bone was strongly different in recession and control group (5,8 mm vs 4,47 mm, p<0.05).
