Effect of electric toothbrush on oral hygiene in nursing home residents tested I randomized clinical trial for 2 months and followed up 12 months after baseline

Patients in nursing homes often have many natural teeth with exposed root surfaces, bifurcations, a complexity of dental restorations like partial prostheses, bridges/crowns, fillings and implants. In addition they have a limited physical ability, like reduced muscular strength, rigidness in the neck and spine. All these factors contribute to make it difficult, both for themselves and their nursing staff to maintain good oral hygiene.

Electrical toothbrushes have been proved effective in removal of dental plaque. There have also been reports from nursing homes that approves of electrical toothbrushes as a helpful aid among the nursing staff.

The present study examine if the overall oral hygiene actually improves with the use of electric toothbrush.
