Edentulous Jaw
Conditions
Brief summary
The palatal rugae, refer to asymmetrical and irregular elevations of the mucosa located in the anterior third of the palate, on each side of the median palatal raphe and behind the incisive papilla. The lack of the rugae area on the polished areas of the dentures has been suggested to impact phonetics in denture patients due to lack of tactile feedback. Therefore, the aim of this randomized crossover clinical trial was to compare patients' reported satisfaction with their complete dentures and oral health related quality of life, when provided with a denture with a rough palatal surface in the rugae area compared with a polished palatal surface or an open palatal surface.
Detailed description
The use of dentures could impact the patients' phonetics which could impact their speech. Phonetics could be affected by multiple factors such as having a proper occlusal vertical dimension, proper occlusal plane, correctly positioned anterior and posterior teeth, and adequate contouring of the palatal surface. The lack of the rugae area on the polished areas of the dentures has been also suggested to impact phonetics in denture patients. The palatal rugae, refer to asymmetrical and irregular elevations of the mucosa located in the anterior third of the palate, on each side of the median palatal raphe and behind the incisive papilla. In addition to enhancing phonetics, the precise reproduction of the rugae in the complete dentures has been suggested to enhance mastication, deglutition and better taste perception. However, these suggestions were based on empirical evidence. Many studies have described methods for replicating the patients rague on complete dentures or modifying the palatal area, however there are no clinical study to ascertain or negate the impact of this procedure. Therefore, the aim of this randomized crossover clinical trial was to compare patients' reported satisfaction with their complete dentures and oral health related quality of life, when provided with a denture with a rough surface in their rugae on the anterior palatal area as opposed to a polished palatal surface or an open palatal surface. The null hypothesis was that there would be no difference in patients' reported satisfaction rate using visual analogue scale (VAS) and Oral Health Impact Profile for Edentulous Patients (OHIP-EDENT) Questionnaire response between the three types of palatal contours after using each type for two month post-delivery.

Masking description
The outcomes assessor will not be aware of which group he/she is interviewing at the assessment session.
Intervention model description
Patients will randomly be allocated to either group P/R/O. Group P: Patients receiving a smooth palatal surface. Group R: Patients receiving a rough surface in the rugae area. Group O: Patients receiving an open surface in the rugae area After insertion, all participants will be followed up for a minimum of 1 week to correct any issues with the dentures and eliminate patient complaints. All patients will be recalled at 2 month after insertion to answer questions using the VAS and to fill out the Oral Health Impact Profile-20 EDENT (OHIP-EDENT), and receive the other type of palatal contour. After the second and third period the same process will be repeated.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 100mm Visual analogue scale of patients' reported overall satisfaction with their dentures | 90 days | Patients overall satisfaction rate using visual analogue scale (a measurement instrument represented in a straight horizontal line of fixed length, 100 mm. The ends are defined as the extreme limits of the parameter to be measured (satisfied and unsatisfied). Orientated from the left 'best' to the right 'worst'). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| OHIP-EDENT Measure | 90 days | Patients reported oral health related quality of life using the Oral Health Impact Profile for Edentulous Patients (OHIP-EDENT) Questionnaire; The OHIP-EDENT index has 20 items and uses a 0-5 scale where 0 is never and 5 is always. The minimum overall score can be 20 and maximum 100. |
| 100mm Visual analogue scale of patients' reported overall satisfaction with their dentures during speaking | 90 days | Patients overall satisfaction rate during speaking using visual analogue scale (a measurement instrument represented in a straight horizontal line of fixed length, 100 mm. The ends are defined as the extreme limits of the parameter to be measured (satisfied and unsatisfied). Orientated from the left 'best' to the right 'worst'). |
| 100mm Visual analogue scale of patients' reported overall satisfaction with their ability to clean their dentures | 90 days | Patients overall satisfaction rate with their ability to clean their dentures using visual analogue scale (a measurement instrument represented in a straight horizontal line of fixed length, 100 mm. The ends are defined as the extreme limits of the parameter to be measured (satisfied and unsatisfied). Orientated from the left 'best' to the right 'worst'). |
| 100mm Visual analogue scale of patients' reported overall satisfaction with their phonetics | 90 days | Patients' reported overall satisfaction with their phonetics using visual analogue scale (a measurement instrument represented in a straight horizontal line of fixed length, 100 mm. The ends are defined as the extreme limits of the parameter to be measured (satisfied and unsatisfied). Orientated from the left 'best' to the right 'worst'). |
