“…All probands were selected from the Caucasian population. Analyses of the CCL and WAG were performed on the following teeth: the maxillary and mandibular canines (13,23,33,43) and the maxillary and mandibular central incisors (11,21,31,41). Since this was an observational cross-sectional study, there was no predetermined sample size.…”

Background The anatomical features of the gingiva and the clinical crowns and their interrelation, especially in aesthetically and functionally demanding areas, are important in complex dental or implant-retained prosthetic rehabilitations. This observational cross-sectional study was designed to evaluate gender- and age-related differences in the width of attached gingiva (WAG), the clinical crown length (CCL), and their interrelation in the anterior teeth to determine the relationship between the pink and white aesthetics. Methods Eighty (54 females, 26 males) fully dentate Caucasian participants between the ages of 20 and 25 years and 36 probands (23 females, 13 males) between the ages of 45 and 55 years were included in the present study. The CCL of the maxillary and mandibular canines, as well as the central incisors of the maxilla and mandible, were determined with a dental sliding caliper measuring from the middle margin of the gingiva at its deepest point to the incisal edge. The clinical investigation of the WAG was performed by inserting a periodontal probe into the gingival sulcus in the middle of the buccal surface to firstly measure the probing pocket depth. The distance between the gingival margin and mucogingival junction (MGJ) was then measured with a Beerendonk sliding caliper in the middle of the labial curvature, and the clinical WAG was determined by subtraction of the measured probing depth. For the statistical analysis, the Mann–Whitney U test, the Wilcoxon-Test, the Spearman’s rank correlation, and a two-factorial non-parametric analysis were used. Results There was no correlation between the CCL and the WAG in a healthy periodontium. Gender influenced the CCL, with men having significantly longer teeth than women in both maxilla (P ≤ 0.01) and mandible (P ≤ 0.05). Age did not influence the CCL significantly neither in the upper (P = 0.06) nor in the lower jaw (P = 0.33). Gender did not show to have a significant influence on the WAG of maxilla (P = 0.69) and mandible (P = 0.26). But differences in the WAG between young and old participants were observed in both upper (P ≤ 0.01) and lower jaw (P ≤ 0.05). Conclusion The present observational study demonstrated that the mean values of cohorts with mixed age groups and genders should not be considered when attempting to determine the ideal relationships between the pink and white aesthetics since the statistical analyses showed significant differences between different age groups and genders.

Background: The vital role of the prosthetic dentistry is not only the restoration of function, comfort and health of oral tissues but also esthetics in general. Upper jaw anteriors commonly seen in smile and contribute to the beauty of a smile. This study may help us to determine standard ideal tooth dimension of maxillary anterior six teeth to restore pleasing esthetics. Aim: To determine the mean width, height and width/height ratio of clinical crowns of natural maxillary anterior six teeth. Setting: Department of Prosthodontics, dental OPD LUMHS Jamshoro. Duration: Six months from 2018 to 2019 Design: Cross-sectional descriptive. Methods: A total of 101 Volunteer subjects with maxillary anterior six teeth present in mouth were included in the study. Impression of maxillary arch was made. The maximum mesiodistal width perpendicular to the longitudinal axis of the tooth and maximum cervicoincisal (CI) length parallel to the longitudinal axis of the maxillary central incisors, lateral incisors, and canines were recorded and width/height ratio was calculated. The final measurements were recorded into proforma. Results: The average age of the subjects was 24.74±3.89 years. The average crown width / length ratio was 0.78±0.12mm for right central incisor and 0.78±0.12mm left central incisor. The average crown W/H ratio was 0.63±0.16mm for right lateral incisor and 0.63±0.14mm left central incisor. Similar the mean crown W/H ratio was 0.64±0.16mm right canines and 0.65±0.18mm left canine. Conclusion: The tooth dimension showed high precision in length/width ratio. Since it showed the least variance in both genders, the crown width-to-length ratio was recognized as the most reliable standard. Keywords: Crown length, Crown width, Ideal tooth dimensions, Maxillary anterior teeth.

“…Maxillary anterior teeth, being the most prominent ones, are paramount to the restoration of anterior dental esthetics as well as overall facial esthetics [ 5 ]. Selection of appropriate crown length and width is essential to creating esthetically pleasing smiles.…”

“…Magne et al, in contrast, utilized extracted teeth to measure CWHR and observed mean ratios of 78% for central incisors and 73% each for lateral incisors and canines [ 9 ]. While Chu [ 10 ] reported a CWHR of 78% for all maxillary anterior teeth using “Chu's esthetic proportion gauge,” Shahid et al [ 11 ] and Yuan et al [ 5 ] utilized digital calipers to measure the dimensions of maxillary teeth and reported significant differences only in terms of crown widths and height between males and females and not in CWHR. With advancements in digital dentistry, 3D digital models and software are now being used for easier and faster measurements of dental clinical parameters [ 7 , 12 ].…”

Objective. To analyze the width and height ratios of maxillary anterior teeth at different crown levels through photographs, 3D, and plaster dental model techniques in a subset of the Pakistani population. Material and Methods. This clinical study consisted of 230 participants. The maxillary impression, standardized photographs, and models were constructed for crown width and height analysis. The SPSS version 25 was used for statistical analysis. Descriptive statistics were carried out for mean, standard deviation, and percentage calculation of teeth width and height, gender, and age of participants. Paired t -test analysis was carried out to compare the dependent variables (teeth size, width, and height ratios) with independent variables (techniques applied, side disparity). A p value of ≤ 0.05 was considered statistically significant. Results. The mean width and height of maxillary anterior teeth obtained through photographs, 3D, and plater models were statistically different. The 3D dental model analysis showed reliable and accurate results. The mean width and height ratio of teeth were different on both sides of the arch. There was a significant difference ( p = 0.001 ) in crown width-height ratios at different crown levels. Conclusion. The width and height ratios in the studied population were different at various crown levels. The dimensions of teeth varied from the incisal to the cervical part of the crown. Hence, rather than relying on a single, fixed ratio of 78% to 80% suggested by researchers for anterior teeth, the clinician should adopt different crown width-height ratios to restore teeth with the optimum esthetic outcome.
