Evaluation of Stain Removal Efficacy and Color Stability of Three Different Dentifrices on Artificially Stained Enamel Surface-An In Vitro Study.

AIM: The aim of the present study was to assess the stain removal ability and color stability of three distinct dentifrices on artificially stained enamel surface. MATERIALS AND METHODS: This study included 75 intact, healthy premolars free of dental caries that were extracted during orthodontic therapy. The samples were allowed to dry for 6 hours after being submerged in the prepared tea solution for roughly 18 hours every day. Then this procedure was repeated for seven successive days. All samples were randomly divided into three experimental groups with 25 samples in each group. Group I: control dentifrice, group II: dentifrice containing hydrogen peroxide, group III: dentifrice containing papain and bromelain. A specially designed toothbrushing simulator was used to brush every sample in the relevant group. Using a spectrophotometer and a measurement program, color measurement was evaluated after staining process after 4 weeks and 8 weeks of teeth cleaning. Using a profilometer, the surface roughness values (Ra) were assessed. RESULTS: After 8 weeks of brushing of stained samples, the color stability was better in dentifrice containing hydrogen peroxide (1.14 ± 0.11) followed by dentifrice containing papain and bromelain (1.22 ± 0.08) and control group (1.30 ± 0.09). And after 8 weeks of brushing of stained samples, the surface roughness was more in dentifrice containing hydrogen peroxide (0.237 ± 0.02) followed by dentifrice containing papain and bromelain (0.229 ± 0.13) and control group (0.207 ± 0.05). CONCLUSION: The present study concluded that the dentifrice containing hydrogen peroxide showed a superior whitening effect on the stained enamel surface than dentifrice containing papain and bromelain and control dentifrice. CLINICAL SIGNIFICANCE: The development of various dentifrice products has been greatly aided by the increased demand for an improved esthetic appearance. Teeth's natural color and any external stains that could accumulate on the tooth surface combine to determine a tooth's color. Additionally, the use of whitening dental pastes to remove external stains has grown in favor. With the development of these whitening toothpastes, dentifrices' ability to lessen or eliminate extrinsic dental stains has increased. How to cite this article: Mishra D, Kamath DG, Alagla M, et al.

Do Parenting Styles Affect Children's Oral Health in Saudi Arabia?

Objective The purpose of the study is to correlate the parenting styles of parents with the oral health of their children, in Riyadh, Saudi Arabia. Study design Two hundred and eighty healthy preschool children, who have never been to the dentist, were recruited. Parenting style was determined by the Parenting Style and Dimensions Questionnaire (PSDQ). World Health Organization (WHO) criteria and simplified debris index (DI-S) were used for the diagnosis of dental caries and oral hygiene of the children respectively. Results Two parenting styles were identified among Saudi parents; authoritative (94%, n = 265) and permissive (6%, n = 17). The majority of children were brushing by themselves (n = 130, 46.1%) and once per day (n = 163, 57.8%). Significant correlations were detected between parenting style and children's brushing times (P-value of 0.016) and the number of meals consumed by children (P-value of 0.031). The age of the child and oral hygiene score were significantly correlated to dental caries (P-value < 0.05). Conclusion Two parenting styles were identified among Saudi parents. Parenting style influenced the child's oral health but not significantly. Early childhood caries and fair to poor oral hygiene were commonly detected among children. Clinically interesting correlations were identified regarding factors affecting the child's oral health status.

Dental and medical health status and oral health knowledge among visually impaired and sighted female schoolchildren in Riyadh: a comparative study.

BACKGROUND: The impact of visual impairment on oral health in the literature is inconclusive, and the available information on the medical and dental health status of visually impaired children is limited. The aim of this study was to evaluate the dental and medical health status, and to assess the oral health knowledge of visually impaired girls aged 6-12 years, and compare them to that of sighted children. METHODS: This analytical cross-sectional study was carried out on 79 visually impaired and 83 age-matched sighted female primary school children. The children's demographic data, medical history, and dental history were obtained through a validated questionnaire. The study population was examined to evaluate their dental caries status using the Decayed Missing Filled Teeth/Surface indices DMFT/DMFS/ and dmft/dmfs for permanent and primary teeth, respectively. Oral hygiene index (OHI), Plaque index (PI) and gingival index (GI) were obtained for periodontal evaluation. Pearson's Chi-square test and t-test were used for the statistical analyses. RESULTS: The general health for both groups was found to be good; however, 21.5% of the visually impaired children had systemic diseases compared with only 4.8% of the sighted children (P = 0.002). Statistically significant differences (P < 0.001) were found between the two groups with regards to OHI. Among the sighted children, 49.4% had good oral hygiene compared with only 22.8% of the visually impaired group. The plaque accumulation was found to be greater among the visually impaired group and gingivitis was also higher. The DMFS score was found to be higher (P = 0.03) among the visually impaired group. CONCLUSIONS: The visually impaired children had more medical conditions and poorer oral health status compared to their sighted peers.
