Oral Hygiene Among Portuguese Older Adults

The goal of this clinical trial was to compare two different oral hygiene instruction methods on oral hygiene behavior in older adults. We also wanted to evaluate the self-perception of oral health changes with each instruction method. The main questions we aim to answer were: * Which method has better results in changing oral hygiene habits? * Which method has better results in reducing bacterial plaque? Participants: * Completed a questionnaire about socioeconomic aspects and oral hygiene habits; * Were examined to assess their oral hygiene status; * Completed a questionnaire about self-perception of oral health; * Received oral hygiene instruction (depending on the group: Generalised Approach or Personalised Technique). Two months later, they were assessed again on oral hygiene habits, oral hygiene status, and self-perception of oral health.
