The oral hygiene of individuals with Parkinson disease (PD) is markedly impaired by difficulties in toothbrushing due to motor impairment and tremors. Additionally, it appears that other features associated with PD have an impact on the quality of oral health. Objective: this cross-sectional observational study characterized the oral health condition of individuals with PD. Methods: fifty individuals with PD, aged 53 to 94 years, users of medication for such condition were examined. The research participants had their oral cavities examined to assess prosthetic use and need; index of Decayed, Missing and Filled Teeth (DMFT); Community Periodontal Index (CPI); Periodontal Attachment Loss (PAL); and oral mucosa. In addition, a questionnaire was applied to obtain personal data, general health, and oral health. The data were analyzed using descriptive statistics. Results: a high prosthetic use was observed in the upper arch (92%), while the lower arch revealed high prosthetic need (66%). The DMFT index showed a high number of missing teeth, CPI showed a prevalence of 43% of dental calculus, and PAL revealed 28% of attachment loss of 4-5 mm. The most frequent findings in the assessment of oral mucosa were denture stomatitis and inflammatory fibrous hyperplasia. Conclusion: PD patients refer xerostomia and present high number of missing teeth, a minority of healthy teeth, and oral lesions, representing a target population for specialized oral health care.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
