The aim of this study was to evaluate a newly formulated mouth rinse containing cymenol in patients undergoing supportive periodontal care in terms of safety (primary outcome) and the impact on dental biofilm and gingival inflammation (secondary outcomes). This research was designed as a pilot, controlled, randomized, parallel, triple-blinded, single-center, clinical trial of a 12-week duration. Adverse events and product perception were assessed by a questionnaire. Clinical, patient-reported outcomes (PROs), compliance, tooth staining, dentin hypersensitivity and microbiological variables were also evaluated. Student T, Mann–Whitney-U and Chi-square tests were applied. Thirty participants (15 per group) were included, randomized and followed for 12 weeks. No adverse events were reported. The questionnaire showed an overall rating of 7.2 (out of 10) in the experimental group and of 8.2 in the control group (p = 0.165) at 12 weeks. No statistically significant differences were observed in terms of gingival health, tooth staining, dentin hypersensitivity or microbiological outcomes between groups at baseline, 6- and 12-week visits. The adjuvant use of the new mouth rinse formulation proved to be as safe as the control product and no significant differences were observed in terms of clinical efficacy. Full article

Chlorhexidine (CHX) is one of the most widely used antiseptics in the oral cavity due to its high antimicrobial potential. However, many authors have stated that the effect of CHX in nonsurgical periodontal therapy is hampered by its rapid elimination from the oral environment. The aim of this study was to determine the antibacterial efficacy of a new compound of chlorhexidine 0.20% + cymenol (CYM) 0.10% on a multispecies biofilm. For this, an in vitro study was designed using a multispecies biofilm model of Streptococcus mutans, Fusobacterium nucleatum, Prevotella intermedia, and Porphyromonas gingivalis. Quantification of the microbial viability of the biofilm was performed using 5-cyano-2,3-ditolyl tetrazolium-chloride (CTC) to calculate the percentage of survival, and the biofilms were observed using a a confocal laser scanning microscopy (CLSM). It was observed that the bactericidal activity of the CHX + cymenol bioadhesive gel was superior to that of the CHX bioadhesive gel, in addition to higher penetrability into the biofilm. Therefore, there was greater elimination of bacterial biofilm with the new compound of chlorhexidine 0.2% plus cymenol 0.1% in a bioadhesive gel form compared to the formulation with only chlorhexidine 0.2% in a bioadhesive gel form.

The primary objective was to assess the safety of a new toothpaste formulation containing cetylpyridinium chloride (CPC) and cymenol as active agents. In addition, clinical efficacy and patient perception were evaluated. A 6-week randomized clinical trial was designed and patients were randomly allocated to use a test or control dentifrice. Adverse effects were assessed at 3- and 6-week follow-up visits, together with the following clinical parameters: Turesky plaque index (PlI), bleeding on marginal probing (BOMP), bleeding on probing (BOP) and Gründemann modification of the stain index (GMSI). Patient-reported outcome measures (PROMs) were also evaluated. A total of 60 patients were randomized and 55 were finally included in the analysis (test, 29; control, 26). Both toothpastes were safe and well tolerated by the patients. Statistically significant differences between test and control groups were observed for BOP changes between baseline week 6 (p = 0.031) and lower levels of plaque were registered in the test group at the 3- and 6-week visits (p < 0.05). No differences were observed for staining or PROMs. The use of a toothpaste containing CPC and cymenol was safe and not associated with any adverse effects. Significantly better clinical results were observed for the test group in terms of PlI levels and BOP reductions. Full article

Objective: xerostomia is a very common problem in the general population. The objective of this study was to determine the efficacy of a new gel and toothpaste in patients with xerostomia, analyze the role of salivary cytokines as biomarkers of xerostomia and assess the possible changes in salivary cytokines following treatment. Materials and methods: A randomized, controlled double-blind clinical study was carried out in 73 patients with xerostomia divided into two groups: placebo and active treatment (cymenol; tocopheryl acetate; D-panthenol; Aloe barbadensis; citrate tribasic dihydrate; fluoride) with oral gel and toothpaste three times a day for four consecutive weeks. The Thomson Xerostomia Inventory was applied, with the assessment of oral quality of life (OHIP-14) at baseline and after four weeks of application of the product. Sialometry was also performed in both groups, with analysis of the IL-1b, IL-6, IL-8 and TNFa levels in saliva. Results: In the active treatment group, the xerostomia scores decreased significantly at the end of the study versus baseline, from 33.47 to 27.93 (p < 0.001). No significant decrease was recorded in the placebo group (34.5 to 32.75; p = 0.190). There were no adverse effects in either group. Regarding the saliva samples, the active treatment group showed significant differences in IL-6 concentration versus the control group (18.55 pg/mL (8–38.28) and 5.83 pg/mL (1.19–12.04), respectively; p = 0.002). No significant differences in salivary cytokines were observed in either the treatment group or the control group. Conclusions: The use of a new toothpaste and gel developed for patients with xerostomia proved effective, with greater symptom relief than in the placebo group. Further clinical studies involving longer time periods and larger samples are advisable in order to confirm the benefits of the described treatment. Full article
