Periodontal disease is an inflammatory condition which affects the covering and support structures of the teeth and, if left untreated, leads to tooth loss. Resorption of the alveolar bone from bi-and trifurcation regions of a multirooted tooth due to the progression of a periodontal disease bears involvement furcation. The degree of furcation involvement is clinically assessed by changes in the vertical and horizontal plane at the root separation area. In the approach of the furcation treatment, the morphological and functional particularities of pluriradicular teeth must be considered and the current techniques look for solutions for the regeneration of the destroyed periodontal tissues. Enamel matrix derivative (EMD) has the role of stimulating healing processes through effects on various growth factors, cement formation, angiogenesis and are used single or in combination with bone graft substitute (BGS) or guided tissue regeneration (GTR) in the complex treatment of periodontal disease. The present study follows PubMed publications on the efficiency of EMD in the treatment of pluriradicular tooth furcations. The findings are that there are not many studies in the usage of EMD associated with the treatment of furcations, but it is an important choice in the complex treatment of destructive periodontal disease, and further studies are needed to be done in periodontal regeneration.

(1) Background: The aim of the study was to evaluate the benefit of combining chlorhexidine with the mechanical treatment of peri-implant mucositis. (2) Methods: Articles from 2016 to 2021 included in the PubMed and Scopus databases were analyzed, following the PICOS criteria and the randomized controlled study model that used chlorhexidine in various forms in the treatment of peri-mucositis. According to the established criteria, a limited number of studies were selected. These studies had as their criteria of evaluation for the effectiveness of chlorhexidine, plaque indices, bleeding indices and depth probing indices. Chlorhexidine has been used after mechanical debridement as a solution, with different concentrations of 0.06%/0.12%/0.2% alone or in a concentration of 0.03%, in combination with 0.05% cetylpyridinium chloride, as well as in the form of a gel with a concentration of 0.2%. (3) Results: The results were assessed to a placebo or other substances, and showed a significant reduction in the indices with a follow-up period ranging from 3 months to 1 year. (4) Conclusions: The association of chlorhexidine with the mechanical treatment of peri-implant mucositis has a role in reducing inflammation, although a complete remission was not obtained in all cases, and the results were not statistically significantly different from the use of other antiseptics.
