The Effect of Palatal Brushing on Denture Stomatitis
Palatal brushing has several advantages including removal of debris and stimulation of blood flow and saliva, which may help to prevent or treat oral diseases, such as denture-related stomatitis in complete denture wearers.
However, there is no previous clinical trial testing this effect. Therefore, the investigators goal is to evaluate whether palatal brushing may change the severity of denture stomatitis and counts of microbes on denture and palatal mucosa.
After an initial exam and data collection, participants will receive instructions about palatal brushing and they will be assessed after 1 and 3 months. Collection of data will include patient-reported information, intraoral photographs and swabbing (for counting microbes).
- There is no difference in the extent of palatal inflammation in edentulous patients with denture stomatitis before and after 3 months of palatal brushing.
- There is no difference in the number of colony forming unit (CFU) of Candida isolated from palate and denture of patients affected by denture stomatitis before and after 3 months of palatal brushing.

|Official Title:||Phase-I Clinical Trial on the Effect of Palatal Brushing on Denture Stomatitis|
- Palatal Inflammation [ Time Frame: 3 months ]
Modified Newton classification 0: Healthy mucosa
1: Type IA, Petechiae in a normal palatal tissue, which are usually found around the orifices of the ducts of the palatal mucous glands 2: Type IB, Localized area of inflammation of the denture-bearing area 3: Type II, Generalised area of inflammation of the denture-bearing area 4: Type III, Hyperplasic palatal surface with inflammation of the denture-bearing area Inflammation area index 0: No inflammation
- Inflammation of the palate extending up to 25 % of the palatal denture-bearing tissue
- Inflammation of the palate extending between 25 % and 50 % of the palatal denture-bearing tissue
- Inflammation covering more than 50 % of the palatal denture-bearing tissue Inflammation severity index
0: Normal tissue
- Mild inflammation
- Moderate inflammation
- Severe inflammation Total score for inflammation = area + intensity (range 0 to 6)
- Candida Species Count [ Time Frame: 3 months ]Candida colony forming units (CFU), defined as the number of colonies formed on a 75 mm agar plate inoculated with collected samples obtained from A)plaque formed on denture surface and B)palatal mucosa.
|Study Start Date:||July 2012|
|Study Completion Date:||March 2013|
|Primary Completion Date:||March 2013 (Final data collection date for primary outcome measure)|
Experimental: Palatal brushing
Palatal brushing after each meal for 3 months.
Behavioral: Palatal brushing
Participants will be instructed to brush their palate with a manual soft-bristle brush after each meal and before sleeping for a period of 3 months. They will be asked to keep to their usual oral and denture hygiene routine during the trial to allow the isolation of the effect of palatal brushing.
