Complete denture palatal rugae design impact on satisfaction and quality of life

OBJECTIVES

To compare the impact of three complete denture palatal rugae designs on participants' satisfaction and oral-health-related quality of life.

BACKGROUND

Complete dentures palatal rugea are usually polished to a smooth finish, which can affect the patient's adaptation. Roughening or keeping an opening in the rugae area to replicate the natural sensation of the palatal rugae has been suggested but lacks clinical evidence.

METHODS

This randomised crossover trial included participants with complete dentures randomly allocated to six sequences. Each sequence alternated between polished, roughened, and open rugae designs. Participants evaluated general and domain-specific satisfaction (eating, taste, speaking, phonetics, and ease of cleaning) on a 100-mm visual analogue scale. They also completed the Oral Health Impact Profile for Edentulous Patients (OHIP-EDENT) and indicated their preferred design at the end. Repeated-measure ANOVA compared satisfaction, and one-way ANOVA with Tukey's test compared OHIP-EDENT scores.

RESULTS

Forty-two participants were randomised. Seven dropped out. General satisfaction ratings were comparable for the polished (Mean = 80.2, SD = 19.7) and roughened designs (Mean = 79.5, SD = 20.2). However, the open design had a significantly lower satisfaction rating (Mean = 41.1, SD = 32.2). OHIP-EDENT scores for the open design (Mean = 44.9, SD = 17.5) were significantly worse than those for the polished (Mean = 36.1, SD = 12.7) and roughened designs (Mean = 36.2, SD = 13.3). Two-thirds of the participants chose the polished design. One-third chose the roughened design; of those, 83% were first-time denture wearers.

CONCLUSIONS

Complete dentures with polished and roughened rugae designs were perceived similarly. Both designs could be recommended based on the patient's preference. However, the open design should be avoided due to negative perception.

Oral health status, oral health related quality of life, and personality factors among users of three‐sided sonic powered toothbrush versus conventional manual toothbrush

OBJECTIVES

This longitudinal within subject controlled randomized observational investigation studied the impacts of three-sided sonic-powered toothbrush versus conventional manual toothbrush on oral health- and oral health-related quality of life (OHRQoL) and assessed the relationship between personality factors and OHRQoL.

METHODS

A total of 96 participants (48 females and 48 males; mean age = 22.61 years, SD = 1.21) were recruited into this investigation and were randomly allocated into two groups. The participants were instructed to control oral hygiene for 1 month using either a three-sided sonic brush (Triple Bristle, Dayton, Tennessee, USA) (sonic group) or a conventional manual toothbrush (manual group). Dental plaque was assessed via Turesky-Modified Quigley-Hein Plaque Index (TMQHPI). Bleeding on probing (BOP) was recorded as 1 if present and zero if absent. The NEO Five-Factor Inventory (NEO-FFI) and Oral Health Impact Profile (OHIP-14) were used to assess personality factors and OHRQoL, respectively. TMQHPI, BOP and OHIP were assessed at study baseline and 1 month later.

RESULTS

The TMQHPI, BOP and OHIP-14 scores were reduced after 1 month in both groups (p < 0.05), and were more reduced among the three-sided sonic brush users (p > 0.05). Higher neuroticism scores were associated with worse OHRQoL (p < 0.05) in both groups after 1 month.

CONCLUSIONS

The three-sided sonic-powered toothbrush was associated with superior oral health and OHRQoL in comparison with the conventional manual toothbrush. Utilizing three-sided sonic toothbrush, less plaque deposits and lower neuroticism scores contributed towards and predicted better OHRQoL after 1 month of oral hygiene maintenance.

Impacts of the Triple bristles three-sided sonic powered toothbrush on tooth shade, plaque control and gingival health

OBJECTIVES

To evaluate the efficacy of the Triple bristles three-sided sonic powered toothbrush in plaque removal and its impact on tooth shade and gingival health, and to compare this with a conventional manual toothbrush.

METHODS

Fifty two participants (26 males and 26 females; mean age [SD] = 22.48 [1.52], SE = 0.210, 95% CI = 22.06-22.90) were recruited into this controlled within-subject, randomized, two-treatment, 1-month crossover and examiner-blinded observational study between October 2020 and January 2021 in the School of Dentistry, University of Jordan. Within each participant, the upper and lower jaws were randomized to receive a brushing protocol either with the Triple bristles three-sided sonic brush or with a soft manual standard toothbrush with flat trimmed bristles. Tooth shades were recorded for upper and lower anterior and premolar teeth. The Turesky-Modified Quigley-Hein Plaque Index (TMQHPI) and bleeding on probing (BOP) were evaluated at study baseline, 1 week and 1 month after applying the brushing protocol.

RESULTS

Both tested brushes were associated with significant reduction in plaque scores and BOP (p < 0.05). The Triple bristles brush was more effective in reduction in plaque and BOP in the lower jaw and among females than the manual brush (p < 0.05).

CONCLUSIONS

The Triple bristles brush was more superior for reduction in plaque and probing on bleeding in the lower jaw and among females.
