SYSTEMIC DISEASE, PATHOLOGY, CARIES
Sixty patients aged between 19 and 40 years were referred to the Department of Periodontology during the study period because of the presence of GR in the upper and lower anterior teeth. The patients were investigated by the principal researcher (WA). The principal investigator searched for healthy patients who have bilateral deep GR with Class I or II according to Miller classification (≥3 mm in depth) at the buccal gingiva of upper or lower anterior teeth. A preoperative clinical examination was done to assess the probing depth and GR classification to determine the included cases. Those who met this condition were 48 patients. Thirty‐two patients were excluded due to the presence of systemic diseases that compromised their general immune status. Moreover, smoker patients, and those who were contraindications for surgery, or their recession defects associated with caries, deep abrasion restoration, or pulpal pathology were also excluded.Therefore, 16 patients (10 females and 6 males) with 2 recessions on the contralateral anterior teeth of the same arch were included in the current research. All included patients, who accepted to participate in this study, signed an informed consent sheet after explaining all the details about the trial and the therapeutic part of it.
