Primary Outcome Measures

Name	Time	Method
Clinical attachment (CAL), measured with a periodontal probe (PCP UNC 15, Hu Friedy) from the bottom of the periodontal pocket to the cementum-enamel-junction, at baseline and 12 months

Secondary Outcome Measures

Name	Time	Method
<br> Measured at baseline and 12 months:<br> 1. Periodontal pockets measured with a periodontal probe (PCP UNC 15, Hu Friedy) from the bottom of the periodontal pocket to the gingival margin<br> 2. Bone sounding (BS) measured with a periodontal probe (PCP UNC 15, Hu Friedy) under anaesthesia in contact to the bone within the periodontal pocket to the gingival margin<br> 3. Radiological bone level (BL) measured on x-rays as the distance from the most apical point of the intrabony defect to the cemento-enamel junction<br>
