Title: Rough Dental Implant Surfaces and Peri-Implantitis: Role of Phase-Contrast Microscopy, Laser Protocols, and Modified Home Oral Hygiene in Maintenance. A 10-Year Retrospective Study

The aim of this study was to evaluate two different kinds of rough implant surface and to assess their tendency to periimplantitis disease, with a follow-up of more than 10 years. Data were obtained from a cluster of 500 implants with Ti-Unite surface and 1000 implants with Ossean surface, with a minimum follow-up of 10 years. Implants had been inserted both in pristine bone and regenerated bone. We registered incidence of peri-implantitis and other causes of implant loss. All patients agreed with the following maintenance protocol: sonic brush with vertical movement,
interdental brushes, and oral irrigators at least two times every day. For all patients with implants, we evaluated subgingival plaque samples by phase-contrast microscopy every 4 months for a period of more than 10-years. Ti-Unite surface implants underwent periimplantitis in 1.6% of the total number of implants inserted and Ossean surface implants showed peri-implantitis in 1.5% of the total number of implants. The total percentage of implant lost was 4% for Ti-Unite surfaces and 3.6% for Ossean surfaces. Strict control of implants leads to low percentage of peri-implantitis even for rough surfaces dental implants.

Title: Pain perception due to laser protocols in dentistry

The purpose of this research is to assess the analgesic efficiency of Photobiomodulation (PBM) in pain reduction in patients during dental therapies in orthodontics, implantology and periodontics. Materials and Methods: we made different RCT where patients were included and allocated to an experimental group [1. orthodontic treatments, as self ligating appliances, clear aligners, Rapid Palatal Expansion, bands on upper molars, and PBM, 2. single implant placement and PBM, 3. comparison between Dye free PDT and LANAP in non surgical periodontal treatment] and a control group (orthodontics, implants and perio only) at random. We used different devices, laser and LED. Patients referred the pain they felt using a Numerical scale rate (NRS), ranging from 0 to 10, with specific intervals of time: 6 h, 12 h, 24 h, and from days 2 to 7. The Wilcoxon-Mann-Whitney test was used to evaluate differences in NRS reported values between the two groups. Results: The pain that was felt at each time interval and the maximum score of pain were significantly lower in the experimental group (p < 0.05) and decreased faster in the experimental group, with a score test near to 0 after 2/3 days. Conclusions: PBM is efficient in reducing the intensity and the time of pain in orthodontics, in single implant placement and in non surgical periodontal protocols.
