The high sensitivity and specificity of salivary IL-1β and PGE2 in identifying periodontitis suggest a potential use as biomarkers for diagnosis of periodontitis presence and severity.

Periodontitis induces an increase in the output of proteins, including mucin and amylase, thereby enhancing the protective potential of saliva, but this is accompanied by a decrease in flow rate.

The close relation between salivary LTB4 and mucin levels suggested that LTB4 might be involved in the defense mechanism of the oral cavity. The correlation of LTB4 with the alveolar bone level indicates that they are one of the mediators responsible for bone resorption.

Candida albicans is involved in periodontal disease, which is influenced by sex hormones. Aim: To study the effects of the estrogen antagonist tamoxifen (TAM) on periodontal disease of oncological patients; clinical oral strains of C. albicans. Patients: With periodontitis and breast cancer and other with AIDS were used. Materials & methods: Periodontal disease was evaluated by the academy of periodontology procedures and the growth of clinical C. albicans isolates were evaluated by the Clinical and Laboratory Standards Institute techniques. Results: Women who consumed TAM for more than 2 years decreased periodontitis severity. In vitro, TAM inhibited the growth of both fluconazole-sensitive and resistant C. albicans. Conclusion: Administered TAM chronically improves periodontal health and has antifungal activity on oral strains isolated from patients with odontologic and medical pathologies.
