Eligibility criteria were: 60-80 years old, ≥20 teeth present (excluding third molars), systemically healthy (controlled systemic disease), not using medication affecting the gingiva. Chronic tobacco smokers were excluded. All participants completed questionnaires, received clinical periodontal examination, and had gingival biopsies harvested for histopathological assessment.Results: Most coca leaf chewers reported several oral changes resulting from the habit, such as bitterness, numbness and mouth dryness, while none of the non-chewers reported experiencing such changes. Within the clinical periodontal parameters, it was found that there was a significant difference in terms of clinical attachment level loss, with a p value of 0.014 in those who chewed coca leaves, who appeared to have less clinical attachment loss.Conclusions: Chewing coca leaf produce bitterness, numbness and mouth dryness, and clinical attachment loss.

Cell proliferation was measured by MTT and BrdU incorporation. Osteogenic differentiation was measured by alkaline phosphatase (ALP) activity. Nodule formation was measured for osteoblast function. The expression of markers of potential signaling pathways (RUNX2, OCN, BSP and Osterix) was evaluated by quantitative PCR.Results: PDL fibroblasts grew at the same rate during the first 5 days in response to both Pam3CSK5 and MPLA. On day 7, cells cultured in the presence of Pam3CSK4 had a significantly higher rate of DNA replication, while cells in MPLA group had a significantly lower DNA replication rate (one-third) compared to the control (p less than 0.05). Pam3CSK4 induced significantly higher ALP activity and larger calcified nodules. TLR4 activation significantly reduced the expression of RUNX2 and osterix and enhanced OCN. Neither TLR2 nor TLR4 affected BSP expression.Conclusions: These data suggest that the activation of TLR2 and TLR4 differentially and perhaps antagonistically modulate osteogenesis by human PDL fibroblasts and have a direct role of TLR-mediated PDL function during periodontal regeneration as a potential target for therapeutics.","PeriodicalId":17281,"journal":{"name":"Journal of the International Academy of Periodontology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8142849/pdf/nihms-1698823.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"38874546","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
