Brief Summary

The objective of this study is to test a personalized oral hygiene instruction form (POHIF) elaborated after oral examination by a dentist and implemented by caregivers in nursing homes or similar medicalized homes.

Conditions

Oral Hygiene, Oral Health; Plaque Score; Dental Plaque Index; Denture Hygiene; Tongue Coating Thickness

Keywords

oral hygiene; oral health; elderly; denture plaque score; dental plaque score; Tongue coating; medicalized homes; nursing homes

Outcome Measures

Primary Outcomes (1)

• Plaque Index (PI) by O'Leary, Drake and Naylor

  It is a simple, non-invasive plaque index utilizing visualization of deposits to assess a person's oral hygiene effectiveness. Plaque index is then calculated using the following formula: (the number of surfaces with plaque) / the total number of available tooth surfaces) x 100. PI percentages range from a minimum of 0% (i.e. no plaque on any tooth surface) to maximum of 100% (i.e. all remaining surfaces are covered by plaque).

  3 weeks

Secondary Outcomes (2)

• Denture cleanliness index modified (DCIM) by Ambjornsen

  3 weeks

• Tongue coating index (TCI) by Shimizu

control group

NO INTERVENTION

In the control group, both independent and dependent residents will receive a hygiene kit and verbal instructions on how to conduct care by the hygienist. Independent residents will perform their oral care themselves. Caregivers will provide oral care to dependent residents.

ACTIVE COMPARATOR

In the intervention group, the participants will receive and oral hygiene kit along with the verbal instruction and in addition to that, they will also receive the written personalized oral instruction form by the second investigator, it will be displayed in the personal bathroom of the residents. For dependent residents, the personalized oral instruction form will be handed to the caregivers along with the personalized oral hygiene kit.

Procedure: personalized oral instruction form

Interventions

personalized oral instruction form PROCEDURE

The investigators will customize the POIF for participants. The POIF will be conceived to have a cover, and participants extraoral photos and intraoral photos will be covered when not conducting oral hygiene, the cover will ensure participants confidentiality. The personalized oral instruction form will be handed to the independent residents along with a hygiene kit comprising the necessary tools to conduct oral hygiene by the second investigator. For dependent residents, the personalized oral instruction form will be handed to the caregivers along with the personalized oral hygiene kit.
