All patients were scheduled for quarterly check-ups for monitoring of orthodontic stability by measurement of intercanine width at the beginning of the study (t0) and every 4 months t1, t2, t3) for 1 year of observation. Patients in the SG additionally participated in a WhatsApp chat group, where they would send, on a weekly basis, snapshots showing his/her occlusion. Every month, the orthodontist acting as the moderator awarded the best five snapshots by publishing a ranking in the chat.Results: Participants in the SG featured smaller changes from the intercanine widths at baseline (at debonding) compared to the CG patients at all times during 1 year of follow-up. Follow-up attendance was regular in both groups in the first 8 months of follow-up. After that, patient compliance decreased in the CG, with eight patients missing check-up appointments.Conclusion: Engaging adolescent patients directly through WhatsApp activity seems to increase regularity in wearing removable retainers, attendance to follow-up schedule, and yield better long-term outcome in terms of orthodontic stability and compliance.Keywords: apps, technologies, orthodontics relapse, orthodontic compliance, patient compliance, young patient
Chromatic Adaption of Two Universal Composites: Spectrophotometric Analysis
No full textObjective: The purpose of this study was to evaluate the chromatic adaptability and color stability of two different composite resins, Omnichroma and Estelite Bulk-Fill Flow, in Class V restorations at different times. Materials and methods: Standardized Class V cavities were prepared on the labial surface of 34 extracted intact and noncarious human permanent molars. The dental elements were randomly divided into two groups according to the resin composite material. Group 1 was restored with Omnichroma (Tokuyama Dental Corporation Inc., Tokyo, Japan) and Group 2 was restored with Estelite BulkFill Flow Universal (Tokuyama Dental Corporation Inc., Tokyo, Japan). Color properties were assessed using a spectrophotometer, SpectroShadeTM Micro (MHT Optic Research, Niederhasli, Switzerland), at baseline (T0), immediately after Class V restoration (T1), 24 h after restoration (T2) and after thermocycling (T3) (ISO/TS 11405, 2015 protocol). Color difference (ΔE) was analyzed with a Student's t-test and a Wilcoxon-Mann-Whitney test to evaluate the differences, in terms of chromatic adaptability, between the two materials (inter-group analysis) while Kruskal-Wallis test e Two-way ANOVA statistical tests were used to evaluate the color stability of each material over time (intra-group analysis). Results: Regarding the inter-group analysis, there were no statistically significant differences between the two materials in all the comparisons: T0-T1 (p = 0.9025), T0-T2 (p = 0.2779), T0-T3 (p = 0.4694). Moreover, both groups showed an average ΔE > 2. In the intra-group analysis, no statistically significant differences were observed in either Group 1 (p = 0.954) or Group 2 (p = 0.8654). Conclusions: The in vitro color matching, assessed by spectrophotometry, of the two tested resin composites does not vary at different time intervals. Furthermore, even though both composites use different mechanisms to produce the color the human eye perceives, they show very similar chromatic adaptability
Impact of adhesive layer addition on the optical properties of remineralized white spot lesions
No full textBackground. The present in vitro study evaluated the camouflage effect of two treatments
for white spot lesions (WSLs): remineralization with Mi Paste Plus© (GC Europe N.V.) and
remineralization combined with a Scotchbond Multi-Purpose© (3M ESPE 2015) adhesive layer.
Additionally, the study assessed the color stability of the treatments when exposed to a staining
agent, such as coffee.
Methods. Sixty extracted anterior and posterior teeth were preserved in saline solution and
divided into two groups. Artificial WSLs were created using 37% orthophosphoric acid for 1
minute. Both groups underwent daily 6-hour remineralization treatments with Mi Paste Plus©
for 14 days. In the second group, a thin adhesive layer was applied after remineralization. Color
analysis was performed using an MHT SpectroShade Micro spectrophotometer at baseline (T1),
after remineralization (T2), after adhesive application for group 2 (TR), and after immersion in
coffee for 24 hours (T3). Color differences (ΔE) between healthy tissue and WSLs were assessed,
with ΔE ≤ 3.3 considered clinically acceptable. Data were analyzed using STATA 17 (P ≤ 0.05).
Results. ΔE analysis showed a statistically significant improvement in the camouflage effect in the
adhesive-treated group (TR) compared to remineralization alone (T2). After coffee exposure (T3),
ΔE values increased significantly in both groups, with higher values observed in the adhesive-
treated group. Intragroup analyses indicated significant differences between T2 and T3, as well
as TR and T3.
Conclusion. The application of an adhesive system can be considered a valid option to improve
the aesthetic outcome of a remineralization treatment; however, this approach carries the risk of
resin staining over time
A Snapshot of Knowledge about Oral Cancer in Italy: A 505 Person Survey
No full textObjectives: Patients' knowledge about oral squamous cell carcinoma (OSCC) plays an important role in primary prevention, early diagnosis, and prognosis and survival rate. The aim of this study was to assess OSCC awareness attitudes among general population in order to provide information for educational interventions. Methods: A survey delivered as a web-based questionnaire was submitted to 505 subjects (aged from 18 to 76 years) in Italy, and the answers collected were statistically analyzed. Information was collected about existence, incidence, features of lesions, risk factors of oral cancer, and self-inspection habits, together with details about professional reference figures and preventive behaviors. Results: Chi-square tests of independence with adjusted standardized residuals highlighted correlations between population features (age, gender, educational attainment, provenance, medical relationship, or previous diagnoses of oral cancer in family) and knowledge about oral cancer. Conclusions: Knowledge about OSCC among the Italian population is limited, and it might be advisable to implement nudging and sensitive customized campaigns in order to promote awareness and therefore improve the prognosis of this disease
