980nm Diode Laser in the Treatment of Periodontal Disease in Cardiac Patients

The study will cover 80 patients under 70 years of age. Initially they will be assigned to three groups: patients generally healthy with periodontitis (P), patients after myocardial infarction with periodontitis (CP) and patients generally healthy with a healthy periodontium (H). Periodontal examination will be performed before treatment, 2 weeks and 3 months after the treatment with a Williams probe calibrated at intervals 1-2-3-5-7-8-9-10mm. Pocket depth (PD), clinical loss of the attachment (CAL) bleeding on probing (BOP), plaque control record (PCR) measurements will be performed. Clinical data will be collected at six sites per tooth (mesiobuccal, midbuccal, distobuccal, mesiolingual, midlingual, and distolingual) of the designated study teeth. PD will be measured in millimeters from the free gingival margin to the base of the probable pocket using a periodontal probe. The presence of BOP will be determined as being present or absent (+/-) within 30 seconds after probing. CAL will be defined as the distance from the cementoenamel junction to t the base of the probable pocket . Patients within CP and P groups will be randomly assigned to one of the two groups (study group and control group) and an later visit will be scheduled. Before treatment, teeth will be rinsed and the study areas will be isolated with cotton rolls and dried gently. Supragingival plaque will then be removed with a sterile curret without coming into contact with the gingiva. GCF samples will be collected from the deepest single root tooth pockets previously identified. The sample will be collected from the deepest pocket using the Periopaper strips (OraflowInc., USA). Before collecting the material, the teeth will be insulated with cotton swabs. The teeth will then be dried with air. The strips will be placed in pockets until a slight resistance is perceived, and they will be left in place for 30 seconds and then transferred to Periotron 8000 (OraflowInc., USA) for the determination of flu
