RESUMO
This study compared tooth color and enamel and dentinal thickness between orthodontically treated and untreated individuals. (1) Methods: A matched case-control study was conducted. The sample included 26 patients who had received orthodontic treatment and 31 matched controls. The color assessment was performed subjectively using the VITA 3D-Master (VM) shade guide and objectively using the VITA Easyshade (VE) spectrophotometer. Differences in L*, a*, and b* (lightness, red/green, and blue/yellow) were calculated. The color change was evaluated using ΔE*ab and the whiteness index (WID). Tooth structure thickness (labiolingual, labial enamel, and labial dentin) was evaluated using cone-beam computerized tomography. The correlations between overall tooth color and tooth structure thickness were evaluated. (2) Results: A total of 228 teeth were evaluated. Color assessment using VM showed significant differences between orthodontically treated and untreated teeth (p < 0.001), while VE revealed no significant differences. Both groups showed no difference in tooth enamel and dentinal thickness. Significant differences in tooth color (p < 0.05) were observed between genders. Both VM and VE showed weak to moderate correlations with tooth color and enamel and dentinal thickness (p < 0.05). (3) Conclusions: Orthodontic treatment may demonstrate visually perceptible but acceptable and clinically undetectable tooth color alteration.
RESUMO
AIM: The study aimed to assess the efficacy of using WhatsApp instant messages in enhancing the oral hygiene in patients with gingivitis. MATERIALS AND METHODS: Forty-three systemically healthy male dental patients with gingivitis were recruited consecutively and randomly divided into two groups: WhatsApp group (n = 24) and a control group (n = 19). At baseline visit, the participants were educated and motivated about oral health and given a folio on instructions about the oral hygiene preventive measures. The participants in the study group further received WhatsApp messages about the dental care at weekly intervals throughout the study (3 months). Plaque index (PI) and gingival index (GI) were measured at baseline and after 1 and 3 months. RESULTS: The averages of PI and GI were not significantly different between both groups at any time point of measurement (baseline, after one, and three months; p value >0.05). Intragroup comparisons revealed that the reductions in PI were highly significant after 1 and 3 months (-0.26 ± 0.26 and -0.57 ± 0.35, respectively, for WhatsApp group, and -0.24 ± 0.27 and -0.64 ± 0.4. respectively, for the control group; p value range: 0.001 to <0.001). Similar were the reductions in GI in each individual group (-0.17 ± 0.46 and -0.67 ± 0.05, respectively, for WhatsApp group, and -0.28 ± 0.29 and -0.69 ± 0.41, respectively, for the control group: p value < 0.001). CONCLUSION: Implementing WhatsApp instant messages does not appear to add extrabenefit to the traditional motivation and education on oral hygiene practices in terms of changes in PI and GI over time in patients with gingivitis. CLINICAL SIGNIFICANCE: Although the results were not motivating, this does not preclude the dental professionals from using WhatsApp and the similar technology to deliver oral healthcare advices.
