    This study evaluated the effect of a mouthwash containing 0.075% cetylpyridinium chloride and 0.28% zinc lactate (CPC + Zn) in a multispecies biofilm model. A 7-days 33-species biofilm, formed on Calgary device, was 1-min treated with: 0.12% chlorhexidine (CHX), culture medium (negative control), 0.075% cetylpyridinium chloride (CPC) or CPC + Zn, 2x/day, from day 3 until day 6. The metabolic activity and the microbial composition were evaluated by colorimetric method and checkerboard DNA-DNA hybridization, respectively. The three antimicrobials (CPC, CPC + Zn and CHX) reduced metabolic activity, total biofilm count and several species counts, including <i>Porphyromonas gingivalis</i>, <i>Fusobacterium nucleatum</i>, <i>Parvimonas micra</i>, <i>Campylobacter gracili</i>s and <i>Streptococcus mutans</i>. However, only CPC + Zn reduced counts of the pathogen <i>Prevotella intermedia</i> and did not interfere with the levels of some beneficial species in relation to the negative control. The treatment of multispecies subgingival biofilm with CPC + Zn was effective in controlling periodontal pathogens and favored the colonization of health-associated bacterial species.

    Perceptions, Attitudes and Needs of Periodontitis Patients: A Qualitative Systematic Review
    (Wiley, 2024) Camila Pinheiro Furquim; Lina J. Suárez; Renata Tavares; Belén Retamal‐Valdes; Murilo Fernando Neuppmann Feres; Magda Feres; Magda Feres; Magda Feres
    Significant physical and psychosocial impacts of periodontitis on patients' lives were identified, along with critical gaps in knowledge and awareness, emphasizing the important role of dentists in patient education. Specific PROs for use in validated instruments tailored to periodontitis were identified. These results can enhance patient-centred care by guiding future studies in accurately assessing patient perspectives on their condition and treatment.
