Detailed Description
Clinical monitoring. MGI (0: no bleeding when a periodontal tube is passed along the mucosal margin adjacent to the implant; 1: visible isolated bleeding points; 2: blood forms a confluent red line at the mucosal margin and 3: profuse bleeding) and the MPI (0: no plaque; 1: plaque recognized only by probing through the smooth marginal surface of the implant; 2: plaque can be seen with the naked eye; 3: abundance of alba matter). PD was determined using a soft plastic periodontal probe for torque-controlled implants at 0.15 N / cm. Three buccal and three lingual reference points for each implant were used to calculate the mean probing depth in millimeters for each implant. PB was dichotomously evaluated: the presence of bleeding was considered positive when it occurred within 20 seconds after insertion of the probe to measure PD. The height of the keratinized mucosa present around each implant was also measured.
All clinical parameters described above were recorded at baseline (pre-intervention period) as well as at 12 and 24 weeks after study initiation.
Treatment of peri-implant mucositis and maintenance care. Prior to the beginning of the intervention, all patients received oral hygiene instruction. Mechanical debridements were performed with titanium curves and polishing using a rubber bowl and polishing paste. In the Test Group the treatment session was completed by a professional topical application around the carboxymethylcellulose gel implants containing 109 colony (CFU) forming units of B. lactis HN019. The gel was applied sub and supragingivally. The patients then received commercial capsules containing the same bacteria and were instructed to dissolve the capsule contents in 20 mL of water and rinse for 30 to 60 seconds, followed by swallowing twice a day for 12 weeks. The control group received the same oral hygiene instructions, mechanical debridement and was treated with gel and placebo tablets. At 3 months postoperatively, the same local mechanical and chemical treatment was repeated for the Test and Control groups.
