The osteoblastic cells incubated for 45 min with ALAD gel as commercialized and exposed for 7 min to the red light of 630 nm LED showed a statistical increase of cell growth, and a stimulatory effect on ALP activity and mineralization.

Photodynamic Therapy by Mean of 5 Aminolevulinic Acid for the Management of Periodontitis and Peri-Implantitis: a Retrospective Analysis of 20 Patients.

The articole showed that in periodontal patients, all sites evaluated had a beneficial effect on PPD, BOP, and MOB with statistically significant differences between baseline and at 3 and 6 months after. For the periimplantitis sites, all patients confirmed that the SRP+ALAD-PDT was not painful, and all perceived a benefit after the treatment at all timing points.

Abstract: Dental implants may be considered a reliable routine procedure in clinical practice for the replacement of missing teeth. Results from long-term studies indicate that implant-supported dental prostheses constitute a predictable treatment method for the management of fully and partially eden-tulous patients.
Implants and their restorations, however, are not free from biological complications.
In fact, peri-implantitis, defined as progressive bone loss associated to clinical inflammation, is not a rare finding nowadays. This constitutes a concern for clinicians and patients given the negative impact on the quality of life and the sequelae originated by peri-implantitis lesions. The purpose of this narrative review is to report on the prevalence of peri-implantitis and to overview the indications, contraindications, complexity, predictability and effectiveness of the different surgical therapeutic modalities to manage this disorder.

Without discriminating between implants placed in native vs. augmented bone, the prevalence of peri-implant diseases was reported from longitudinal and from cross-sectional studies, respectively. The outcomes of a systematic review with meta-analysis reported a weighted mean prevalence of peri-implant mucositis of 43% (range: 19–65%) and of peri-implantitis of 22% (range: 1–47%), respectively.
