Impact of oral health management on mental health and psychological disease: a scoping review

Dental decision-making for persons with dementia: A systematic narrative review

Dental decision-making represents the establishment of a common understanding between the dental professional and the recipient of the intervention, which determines oral healthcare and dental treatment policies. Dental decision-making for persons with dementia can be challenging, and there have been no systematic reviews on this topic. Therefore, this systematic narrative review aimed to identify the current state of dental decision-making in persons with dementia. Literature search was performed using PubMed, Web of Science, Cochrane Library, CINAHL, and Google Scholar databases. Through the process of research selection, 7 articles with a high risk of bias were included in this study. This review clarified that there is limited information on the dental decision-making processes for persons with dementia. In conclusion, although this may be difficult due to different medical and socioeconomic conditions, the dilemma between the need to establish evidence for dental decision-making and medical ethics that prioritize a patient-centered position should be discussed globally in the future.

Impact of natural disaster on oral health: A scoping review

Natural disasters may affect oral health as a result of serious damage to social function and public health. However, no article has systematically summarized the impact of natural disasters on oral health. This review aimed to map the existing literature on the impact of natural disasters on oral health. Targeted literature was searched using PubMed, Web of Science, Cochrane Library, and CINAHL databases with the keywords "disaster" and "oral health." Eligibility criteria were established based on the Participant-Concept-Context model, and eligible studies were identified based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 flow diagram. Eight eligible studies related to earthquakes were included in this review. Of these, 7 studies were related to the 2011 Great East Japan Earthquake. Oral health status of victims of disaster was analyzed by assessing the following parameters: questionnaire surveys; examination for fungal infection; and analyses of the teeth, periodontal, and oral hygiene condition. Six studies suggested that natural disasters had a negative impact on oral health. Two studies could not determine the impact of natural disasters on oral health. Only 1 study analyzed the impact of disasters on oral health based on pre- and postdisaster surveys. This scoping review found that there was insufficient evidence to suggest a relationship between natural disasters and oral health and that there are biases in geographical areas and types of natural disasters in this research field. Further research is needed to promote evidence-based support by dental professionals during different disaster phases.
