AbstractThis study aimed to noninvasively assess the relationship between the labial gingival thickness (GT) and the underlying bone thickness (BT) of maxillary anterior teeth by two digital techniques. A total of 30 periodontally healthy participants with 172 maxillary anterior teeth were enrolled. GT and BT were measured at 2, 4 and 6 mm apical to the cemento-enamel junction (CEJ) by two digital techniques: M1—cone-beam computed tomography (CBCT) and M2—digital intraoral scanning (DIS) combined with CBCT. The Pearson's correlation coefficient was calculated to determine the correlation between GT and BT. A significant negative correlation was identified between GT and BT at 2 mm apical to the CEJ for central incisors (CI), lateral incisors (LI), and canines (CA) both by M1 and M2, while a weak negative correlation at 4 mm apical to the CEJ was observed by M1 for CA. No significant correlation was found at other sites by both M1 and M2. The labial BT was < 1 mm in most cases (85% of CI; 97% of LI; and 90% of CA). Within the limitation of this study, it was concluded that GT and BT seemed to be negatively correlated at 2 mm apical to the CEJ. Therefore, caution is warranted when implant restoration at the esthetic area of the anterior teeth.

SUMMARY Examining three bleaching systems, this in vivo clinical trial evaluated the relationship among tooth sensitivity, light activation, and agent concentration, and it correlated dental sensitivity with tooth thickness. Materials and Methods: Eighty-seven volunteer patients were included. Inclusion criteria were the presence of anterior teeth without restorations as well as the absence of a previous bleaching experience and absence of noncarious cervical lesions or dental pain. Exclusion criteria included pregnancy or breastfeeding, a maximum of TF3 hypoplasia, tetracycline-fluorosis stains, malpositioned teeth, orthodontic treatment, periodontal disease, and/or analgesic/anti-inflammatory intake. Patients were randomly assigned to three bleaching groups: Group A (n=25) was treated with 15% H2O2 and nitrogenous-titanium-dioxide and was light activated (Lase Peroxide Lite, DMC, SaoCarlos, Sao Paulo, Brazil); Group B (n=27) was treated with 35% H2O2 and was light activated (Lase Peroxide Sensy, DMC); and Group C (n=35) was treated with 35% H2O2 (White Gold Office, Dentsply, 38West Clark Ave., Milford, USA) without light activation. Tooth sensitivity (TS) was self-reported by the patients using the visual analog scale (VAS) at baseline (TS0), immediately after treatment (TSI), and at seven days after treatment (TS7). In 46 patients, tooth thickness was determined by computed tomography. TS0, TSI, and TS7 were compared between the A and B groups to determine the effect of concentration and between the B and C groups to determine the effect of light using analysis of covariance. The correlation between tooth thickness and TSI was determined by Spearman Rho test (SPSS 15). Results: Eighty-seven patients were evaluated at baseline, and 61 were evaluated at seven days. Separated by groups, tooth sensitivity, expressed as VAS value at the time points TS0, TSI, and TS7, respectively, were as follows: Group A: 13.76 ± 13.53, 24.40 ± 25.24, and 5.94 ± 5.5; Group B: 15.07 ± 18.14, 42.4 ± 31.78, and 8.68 ± 17.99; and Group C: 10.80 ± 14.83, 31.51 ± 29.34, and 7.24 ± 9.2. Group A showed significantly lower tooth sensitivity than group B at TSI (p=0.032). No differences were observed in the tooth sensitivities between groups B and C. No correlation was encountered between tooth thickness and tooth sensitivity immediately after treatment (Rho=−0.088, p=0.563). The median tooth thickness was 2.78 ± 0.21 mm. Conclusions: Increases in the concentration of bleaching agents directly affect tooth sensitivity, and LED/laser activation and tooth thickness are not correlated with tooth sensitivity after dental bleaching.

The Relationship

Aim: to assess the relationship between deep overbite with palatal impingement and periodontal health status in a cohort of adult Saudi dental patients. Materials and Methods:Ten patients (4 males and 6 females, aged 16 to 31 years old) with deep traumatic overbite and palatal impingement were examined. A Hawley retainer appliance with an anterior bite plate was provided for all patients.Pocket depth, bleeding index, gingival index, plaque index and mobility were recorded for four visits after using the appliance with fixed intervals in-between. Repeated measures analysis of variance (ANOVA) was used to assess the differences between visits, control /experimental teeth and surfaces (palatal /labial) for pocket depth, bleeding index, plaque index,gingival index and mobility.

The Relationship

Objective: To evaluate the relationship between inner canthal distance and maxillary anterior teeth width withrespect to age, gender and ethnicity. Study Design: Cross sectional study. Place and Duration of Study: Altamash Institute of Dental Medicine, Karachi, from Aug 2019 to Jan 2020. Methodology: One hundred participants from both genders with full permanent dentition, no interdental space or pathology and facial symmetry were included in this study. The measurements were carried out with digital Vernier caliper. SPSS-25 was used for statistical analysis. Results: The mean ± SD of inner canthal distance and width of maxillary anterior teeth were 2.99cm ± 0.46and 3.82cm ± 0.35 respectively. A significant difference was found between gender (p=0.037) and inner canthaldistance. The maxillary anterior teeth width and inner canthal distance varies amongst different ethnicities(p=0.01). The inner canthal distance does not vary with advancing age (p=0.87) whereas width of maxillaryanterior teeth varies (p=0.04). A weak correlation value of 0.47 was found between inner canthal distance andmaxillary anterior teeth width. Conclusion: This research suggests that there is a weak relationship between inner canthal distance and maxillary anterior teeth width. Therefore, a multiplication ratio of 1.27 is advised to get combined mesiodistal width of maxillary anterior teeth. Additionally, the value of both differs in various local ethnicities. Inner canthal distance does not vary with age though has significant gender disparities while maxillary anterior teeth width remains constant.

The Relationship

Smile is one of the facial expression that are essential in expressing friendliness, agreement, and appreciation. Most patients that come to dentist to have treatment for an attractive smile. One of the component to make an attractive smile is smile arch. Smile arch have been the interest of the orthodontist in recent years. Smile arch is the relationship between a hypothetical curve drawn along the edges of the maxillary anterior teeth and the inner contour of the lower lip in smile. This study was to differ male and female’s smile type base on smile arch. This study was to evaluate of smile type based on smile arch with gender. A total of 31 females and 31 males were selected among criteria inclusion. Photographs taken with digital camera showing the subjects with a posed smile were used for this study and Adobe photoshop used to determine the smile arch. Student Mann Whitney test were used for statistical analysis. The resulting data showed that significantly difference (p<0,05) between smile arch and gender. The most common female’s smile are parallel smile (64.5) and male’s smile are straight smile (51.6%). In this study concluded that the curvature of the incisal edge anterior maxilla appears to be more pronounced or parallel for woman than for a men.
