Brief Summary

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.

Detailed Description

This study aimed to evaluate the effectiveness of two different oral hygiene instruction methods on oral hygiene behavior in older adults. Secondly, we intended to assess the self-perception of oral health changes with each instruction method.

This study was a clinical trial that included a convenience sample of 60 participants attending a university dental hospital (Egas Moniz Dental Clinic, Almada, Portugal).

Data were collected in two phases: The first phase (baseline) consisted of three parts: a questionnaire focusing on the participant's socioeconomic data and oral hygiene behaviors, clinical records obtained through an intraoral examination, using the Oral Hygiene Index-Simplified (OHI-S), and oral hygiene instruction.

For the oral hygiene instruction, the sample was divided into two groups of 30 participants (n=30) each group, exposed to different methods of professional education. The first one, identified as "General Approach" (GA), focuses more broadly on the different topics of oral diseases and oral hygiene care. The second group, identified as "Personalised Technique" (PT), was based on the specific needs of each participant.

After two months, to establish a follow-up session, the self-reported questionnaire on oral hygiene behavior and self-perceived oral health was administered again and the same clinical records on OHI-S were collected.

Primary Outcome Measures
NameTimeMethod
Interdental devices usage2 months

Assessment of dental floss or interdental brushes usage (yes/no)

Denture care2 months

Assess whether participants sleep with their dentures in (yes/no)

Treatment needs (oral clinical observation)2 months

Assessment of participants' treatment needs (yes/no)

Brushing frequency2 months

Assessment of toothbrushing frequency (\<2x/day or ≥ 2x/day)

Oral Hygiene Clinical Indicator2 months

Assessment of Oral Hygiene Index - Simplified (OHI-S) (Greene \& Vermillion, 1964). The six surfaces examined for the OHI-S are selected from four posterior and two anterior teeth. For posterior teeth, the buccal surfaces of the selected upper molars (usually 16 and 26) and the lingual surfaces of the selected lower molars (usually 36 or 46) are examined. For the incisors, the labial surfaces of the upper right central incisor (11) and the lower left central incisor (31) are evaluated.

A score from 0 to 3 was then recorded for each surface, according to the classification for each index (debris or calculus). For each participant, the debris or calculus index was obtained by summing the scores and dividing by the number of surfaces scored.

The Simplified Oral Hygiene Index is the sum of the Debris Index and the Calculus Index and can range from 0 to 6, with higher scores indicating poorer oral hygiene.

Denture hygiene2 months

Assessment of daily denture cleaning (yes/no)
