A 2D Photographic and 3D Digital Dental Model Analysis of Golden Percentage in Maxillary Anterior Teeth.

The objective of this paper was to evaluate the existence of golden percentage in natural maxillary anterior teeth with the aid of 3D digital dental models and 2D photographs. And to propose regional values of golden percentage for restoration of maxillary anterior teeth. For this purpose, one hundred and ninety dentate subjects with sound maxillary anterior teeth were selected. Standardized frontal images were captured with DSLR, and the apparent width of maxillary anterior teeth was measured utilizing a software on a personal laptop computer. Once the dimensions were recorded, the calculations were made according to the golden percentage theory (GPT). The data were analyzed by independent and paired T-test. The level of significance was set at p < 0.05. The golden percentage values were not found in this study. The values obtained were 16%, 15%, 20%, 20%, 15%, and 16% moving from the right canine to the left canine teeth. There was no significant gender difference in the golden percentage values. Thus, golden percentage should not be used solely for the correction of anterior teeth or for determining dental attractiveness. Emphasis should be given to a range of dental proportion on regional basis.

Evaluation of Maxillary Anterior Teeth Width and Their Relation to the Calculated Values for Smile Designing

The present study was conducted to determine the golden proportion, golden mean, and the Preston proportion of the individuals between the widths of six maxillary anterior teeth and to determine which proportional formula exists in the population. This study was conducted among 60 participants between 18 years and 30 years of age with an esthetic smile. They were grouped into 30 females and 30 males. Maxillary arch impressions were made using irreversible hydrocolloid material from each individual. The width of the anterior teeth on the graph paper was analyzed by using digital vernier caliper. The data were statistically analyzed by one way ANOVA test. The study revealed that the formula of golden proportion and golden mean had no statistical differences between males and females but the Preston proportion has shown statistical differences in the total population. From the current study, it was concluded that the formulas of golden mean and golden proportion proposed by Ward can be used for smile designing and full mouth rehabilitations. Demand for smiles has gained its importance with time. The golden proportion, golden mean, and the Preston proportion are the guidelines used by the professional for better esthetic proportion in the dentition.

Revealing Stature and Facial Proportions from Teeth: An Adjunct to Forensic Science

Background: Teeth and skull remains are often some of the evidences available that can be used reliably for identification in medicolegal cases. Determination of Stature and facial proportions from teeth dimensions have not been utilised fully in the field of forensics. This study was designed with the aim to estimate stature as well as facial proportions from teeth and head measurements. Objectives: To correlate height of an individual to combined mesiodistal width (CMDW) of maxillary anterior teeth and head circumference and to correlate the facial height and facial width to the cervicoincisal and mesiodistal dimensions of maxillary central incisor. Methodology: This was a descriptive cross-sectional study conducted among 1000 patients of age group 18–30 years of Kerala origin by birth and domicile who fulfilled the inclusion and exclusion criteria. Study variables included length and width of the face, combined mesiodistal (MD) width of maxillary anterior teeth, mesiodistal and cervicoincisal dimension of maxillary central incisor, circumference of the head and height of the individual. The results were statistically analysed using Karl Pearson’s correlation coefficient. Results: Correlation between height and head circumference, height and combined mesiodistal width of maxillary anterior teeth, width of face to mesio-distal width of maxillary central incisor showed significant correlation with p value &lt;0.05, but the correlation coefficients were very weak. But while correlating facial length to cervicoincisal length of maxillary central incisor the values obtained were not statistically significant.

DETERMINATION OF THE COMBINED WIDTH OF MAXILLARY ANTERIOR TEETH USING INNERCANTHAL DISTANCE WITH RESPECT TO AGE GENDER AND ETHINICITY

Objective: To evaluate the relationship between inner canthal distance and maxillary anterior teeth width withrespect to age, gender and ethnicity.&#x0D; Study Design: Cross sectional study.&#x0D; Place and Duration of Study: Altamash Institute of Dental Medicine, Karachi, from Aug 2019 to Jan 2020.&#x0D; 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.&#x0D; 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.&#x0D; 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.

Maxillary anterior teeth dimension and relative width proportion in a Saudi subpopulation

ObjectivesAchieving a natural smile while restoring anterior teeth is challenging. Selecting appropriate dimensions of teeth is important for aesthetics. This study aims to measure and analyse the dimensions of the maxillary anterior teeth and their relative width proportions in a Saudi subpopulation. MethodsOne hundred and eighty patients (112 men and 68 women) with intact maxillary anterior teeth (age range = 20–30 years) participated in this research. Maxillary impressions (Vinyl Polysiloxane) were created and poured. A digital caliper was used to record the length and width of maxillary anterior teeth in millimetres (mm) from the dental casts, and the casts were digitally photographed to calculate relative width ratios. ResultsThe mean width for central incisor was 8.74 mm (men = 8.89 mm, women = 8.60 mm), lateral incisor 6.64 mm (men = 6.79 mm, women = 6.49 mm) and canine 7.82 mm (men = 8.01 mm women = 7.63 mm). The recorded mean lengths for these teeth were 9.84 mm (men = 10.04 mm, women = 9.64 mm), 8.09 mm (men = 8.30 mm, women = 7.89 mm) and 9.08 mm (men = 9.48 mm, women = 8.69 mm). The mean values of apparent width/width ratio measured on the cast photographs were 63.69 mm for the lateral incisor/central incisor and 78.35 mm for canine/lateral incisor. No statistically significant difference was found between the mean values of the apparent width/width ratio of the right and left sides and between men and women. ConclusionsThis study showed a minor asymmetry between left and right side anterior teeth among the participants. The width to length ratio of the central and lateral incisors was similar for both genders, with minor differences in the canines. A squarish form of anterior teeth for the Saudi population with dimensional similarities to the Turkish population was found.

Evaluate the Association between the Interpterygomaxillary Notch and the Width of Maxillary Anterior Teeth

Aim: Among the most challenging aspect of complete denture construction is the proper selection ofmaxillary anterior teeth. The main objective of this study was to examine the relationship between the totalmesiodistal width of the six maxillary anterior teeth and the interpterygomaxillary notch distance.Materials and Methods: One hundred maxillary impressions were taken on subjects using irreversiblehydrocolloid impression material and stock trays. The distance between two pterygomaxillary notcheswas measured on a straight line using a digital caliper with a 0.01-mm precision level. For each cast, themaximum coronal widths of each of the maxillary anterior six teeth were measured with a caliper. Theresults were analyzed using correlation regression tests.Results: The mean mesiodistal width of the six maxillary anterior teeth was 52.97 (+2.29) mm, and the meandistance of the interpterygomaxillary notch was 44.28 (+ 3.29) mm. The corelation and regression testsshowed that there was a stastically significant positive corelation (p=0.001), Pearson coefficient = 0.498between the interpterygomaxillary notch distance and total mesiodistal width of the six maxillary anteriorteeth.Conclusion: The majority of cases showed a significant relationship between the interpterygomaxillarynotch distance and total mesiodistal width of the six maxillary anterior teeth. Though other parametersshould also be considered to analyze and compare other morphological structures to improve the aestheticrequirement for the conventional denture wearer.

Accuracy of trial restorations from virtual planning: A comparison of two fabrication techniques

Statement of problemDifferent technologies have been used to fabricate trial restorations. However, studies investigating the accuracy of trial restorations fabricated with different techniques in comparison with the initial 3-dimensional virtual design are lacking. PurposeThe purpose of this clinical study was to evaluate completely digital workflows for managing the esthetic outcome through the production of trial restorations with 2 different technologies: stereolithography apparatus (SLA 3D) and computer-aided design and computer-aided manufacturing (CAD-CAM). The aim was to determine which of them provided trial restorations more similar to those of the 3D virtual design. Material and methodsThirty participants who did not meet ideal esthetic proportions for the anterior maxillary teeth were enrolled. For each, 2 intraoral and extraoral frontal photographs and intraoral digital scans were made. The digital images were processed by using the Digital Smile System (DSS) software program to have a smile preview after the treatment. Virtual designs were matched with the surface tessellation language (STL) files from the intraoral scans and edited by exocad DentalCAD to create custom trial restorations using SLA 3D and CAD-CAM technologies. Two independent examiners measured the virtual restorations by using virtual calipers in the software program and then the trial restorations by using digital calipers. The measurements were carried out from the incisal edge to the gingival margin, mesial-distal widths of the central incisors, and the distance from the distal margins of maxillary right and left canines. The trial restorations were evaluated intraorally for fit. The participants approved the definitive treatment outcome after the evaluation. The normality of data was verified with the Shapiro-Wilk test, and the Friedman test for matched groups with the Bonferroni and Dunn tests for multiple comparisons were used (α=.05). ResultsComparing the 3D designs with the printed trial restorations, a significant increase was only found in the mesial-distal width of central incisors (P<.05), while the milled trial restorations showed a significant increase (P<.05) of all measurements except for the maxillary right and left canines. Comparing printed trial restorations with the milled ones, the only significant difference was found in height measures of maxillary right central incisor, with the milled trial restorations exhibiting higher values than the printed ones (P<.05). The printed trial restorations showed good clinical fit, and the milled restorations had poor clinical adaptation. ConclusionsThe accuracy of printed trial restorations was higher than that of milled trial restorations, except for the canine to canine width of maxillary anterior teeth. However, this difference did not compromise the fit of the printed trial restorations. The milled trial restorations had increased dimensions in comparison with the measurements made in 3D designs, and consequently, their clinical fit was compromised. SLA 3D- printing technology provided the best fit.

Evaluation of the golden proportion and golden standard of maxillary anterior teeth in relation to smile attractiveness

Objective: The present study aimed to explore the existence of golden proportion (GP) between the widths of maxillary anterior teeth and golden standard (GS) for width to height ratio of maxillary central incisor in individuals with attractive and non-attractive smiles. Material and Methods: A total 82 females were recruited and divided into 2 groups: attractive smile (n=41) and non-attractive smile (n=41). Frontal photographs were taken, scanned, and saved in a personal computer. The apparent mesiodistal width of each anterior tooth was measured. The data were analyzed using the appropriate statistical tests at a P-value of &lt;0.05. Results: Frequency of GP was very low among the total sample, and most proportions were higher than GP. No significant differences were found between both groups in relation to central-to-lateral ratio while, significant differences were found in relation to canine-to-lateral ratio. Similarly, most proportions of width to height ratio were higher than GS. Differences between groups were significant for the left side and for both sides (P&lt;0.05) but was not for the right side (P&gt;0.05). Conclusion: Frequency of the golden proportion was very low among the study population. Smile attractiveness was not greatly related to the proportions between the teeth. KeywordsGolden proportion; Golden standard; Attractive smile; Esthetic; Anterior teeth.

Golden proportion evaluation in maxillary anterior teeth amongst Saudi population in Riyadh

IntroductionIn achieving pleasing dental aesthetics, the maxillary anterior teeth are essential. Numerous methods are used to measure their dimensions, including the golden proportion between their perceived widths and the width-to-height ratios, referred to as the golden proportion and is considered as a gold standard for esthetic evaluation.The objective of this study was to evaluate the existence of the golden proportion between the width of the maxillary anterior teeth of Saudi males and females. MethodsThis clinical observational study included a total of 61 participants that met the inclusion criteria having 36 females and 25 males, all Saudi nationals, presented to Princess Nourah bint Abdulrahman University (PNU), College of dentistry, clinics. Dental casts of the maxillary arches for each participant were made after taking digital impressions in addition to taking photographs. The dimensions and the perceived width of the anterior teeth viewed from the front were measured using a digital caliper. SPSS was used to analyze the data. ResultsThere were significant differences between the subject’s width-to-height ratios and the golden proportion of 0.80 where (p-value < 0.05). Thus, indicating that no golden ratio was observed except in case of tooth number 12 in male subjects where mean value was (0.83) with a standard deviation of (0.09) and the p-value of (p = 0.144) > 0.05. ConclusionsFrom the perceived widths of maxillary anterior teeth, the golden proportion was not found to exist. No gold standard was detected for the width-to-height proportions of maxillary incisors. Therefore, in addition to anterior teeth measurements, specific population characteristics and perception of an agreeable smile should be considered for evaluating esthetics.

Evaluation of “Golden Proportion” in Saudi individuals with natural smiles

BackgroundThe Golden Proportion (GP) has been considered by many as the most harmonious recurrent tooth-to-tooth ratio and has long been proposed as an aesthetic guideline for restoring/replacing maxillary anterior teeth. Researchers investigated GP in various populations. PurposeThe aim of the current study was to investigate the occurrence and prevalence of the GP between the perceived widths of maxillary anterior teeth in a Saudi population with natural smiles. Materials and MethodsA total of 360 Saudi dental students (180 males and 180 females) with natural smiles and who met the inclusion criteria were included in the study. Frontal photographs were captured for all participants while maximally smiling using a digital camera with standardized settings. Photo-editing software was used to measure the perceived mesiodistal width of each anterior maxillary tooth in all digital images. Paired and student t-tests were performed to detect side and/or gender differences respectively. Calculated ratios of the perceived mesiodistal widths of the teeth were compared with their respective GP values using a one sample t-test. Statistical significance was set at 5%. ResultsFor both genders, there were significant differences (P < 0.001) between the calculated ratios and the golden ratios. No side differences in the GP were detected. Males had wider teeth than females however significant differences between genders was detected for the centrals (P < 0.001) only. ConclusionsWidth ratios of the maxillary anterior teeth did not follow the GP for the examined Saudi population. Males had wider anterior teeth with the centrals exhibiting a significant gender-based difference. There was no side-dependent variation for both genders.

Dimensional Relationship between Maxillary Anterior Teeth and Inter Hamular Distance

Introduction: Selection of anterior teeth for the fabrication of artificial denture during Prosthodontic rehabilitation is a complex process. Different authors have suggested various methods, however no single method can be used reliably to select artificial teeth. This study aims to assess dimensional relationship of maxillary anterior teeth with inter hamular distance which may assist in the artificial teeth selection.&#x0D; Materials and methods: This clinical study was carried out on 95dentate subjects meeting the inclusion criteria. Prior to impression making, hamular notch was located precisely with T-burnisher and was marked with indelible pencil. Impression of maxillary arch was made using irreversible hydrocolloid impression material and casts were poured using Type III dental stone. Measurements were made directly on the cast using digital vernier caliper. The contact point widths of maxillary right and left maxillary central incisors, lateral incisors and canines were measured. The distance between the right and left hamular notch was measured. The sum of contact point widths of all maxillary anterior teeth was calculated. All the data were recorded and statistically analyzed.&#x0D; Result: There is a positive correlation between combined width of maxillary anterior teeth and inter-hamular notch distance with Pearson’s correlation coefficient (r) 0.217 and p value 0.035 which is statistically significant.&#x0D; Conclusions: There is significant correlation between combined width of maxillary anterior teeth and distance between right and left hamular notch. This correlation is valuable and practicable in estimating the six maxillary anterior teeth width.

Relationship Between Width of Maxillary Anterior Teeth and Interalar Distance

There are few guides to estimate the size of denture teeth. The purpose of this observational cross sectional study of Iranian adults was to evaluate the relationship between interalar width compared to intercanine tip distance and to the summed width of the maxillary anterior teeth in adults. The samples were selected from dental students in Isfahan University. Interalar width was measured with calipers. Maxillary inter-canine distance was measured between cusp tips on dental casts. Mesiodistal widths of the six anterior teeth also were measured. Independent t-tests, Pearson’s correlation coefficients, and linear regression were used for statistical analysis. Mean interalar width was 36.38 mm (sd = 3.81), intercanine tip distance was 34.15 mm (sd = 2.05), and mean width of maxillary anterior teeth was 48.23 mm (sd = 2.07). There were significant associations between interalar width and summed widths of the maxillary anterior teeth and with intercanine distance. In addition, predictive equations for estimation of tooth sizes using interalar width were calculated by regression. These statistical relationships may also be useful forensically.

Clinical Evaluation of Maxillary Anterior Teeth in Relation to Golden Proportion, Red Proportion and Golden Percentage

Golden proportion, recurrent esthetic dental proportion and golden percentage are the widely accepted tools to measure perceived mesiodistal width of maxillary anterior teeth. Our study was aimed to identify appropriate tool among the above mentioned proportion to measure perceived mesiodistal width. A cross-sectional observational study was conducted in National Academy of Medical Sciences, Bir Hospital, Nepalese Army Institute of Medical Sciences and Patan Academy of Health Sciences between March 2014 to March 2015.Sixty-three respondents were recruited in the study by the convenient sampling technique. Photographs of the maxillary anterior teeth were taken using digital single reflex camera with macrolens. Data analysis was done using SPSS version 17.0 and paired sample t- test was performed. In our study the golden proportion was 14.28% between central and lateral incisor and 12.69% between canine and lateral incisor. Therefore, golden proportion in our scenario doesn't exist. Recurrent esthetic dental proportion in female Aryans was 71 and 71 on left side and 71and 75 on right side. Golden percentage of respondents was near to values 11, 15, 22, 22, 15, and 12 %. Golden percentage is an appropriate anterior tooth proportion which may serve as a guideline for the restoration of anterior tooth. RED proportion is applicable only in Mongoloid female population.

Determination of Correlation of Width of Maxillary Anterior Teeth using Extraoral and Intraoral Factors in Indian Population: A Systematic Review

ABSTRACT Introduction Various anthropometric measurements have been used to determine the size of maxillary anterior teeth. However, which anthropometric measurement is the most reliable indicator to determine the width of maxillary anterior teeth remains unclear. Aims and objectives To evaluate which anthropometric measurement is the most reliable indicator in determining the width of maxillary anterior teeth. Materials and methods An electronic search was conducted for scholarly articles discussing various anthropometric measurements used for determination of width of maxillary anterior teeth, written in English or translated into English listed with PubMed, Cochrane Library, ScienceDirect, Wiley Online Library, and Google scholar databases. The search strategy yielded 119 articles. Out of them, 70 were excluded following reading of abstract, and 49 were selected for full-text reading. Of these, 21 were excluded based on exclusion criteria. Finally, 28 articles were included for final search. Due to heterogenicity of studies, a meta-analysis was not performed. Results High degree of correlation was seen between interalar width (IAD), interpupillary distance (IPD), bizygomatic width (BW), and width of maxillary anterior teeth, in Indian population, whereas in Saudi population, intercanthal distance (ICD) has high degree of correlation to the width of maxillary anterior teeth, and in Brazilian (mulatto and blacks) population, high degree of correlation was seen between intercommissural width (ICOW) and width of maxillary anterior teeth. Conclusion The anthropometric measurement used depends on the population group in which it is being used. There is no single anthropometric measurement that can be used to determine the width of maxillary anterior teeth. Hence, more studies with large sample size and different population groups need to be conducted. Clinical significance In Indian population, high degree of correlation was seen between IAD, IPD, BW, and width of maxillary anterior teeth. The results of the previous study should be validated by including a large population size spread over entire Indian subcontinent. This would also help to generate multiplication factor for various anthropological measurements for use limited to the Indian population.

Correlation between Interalar Distance and Mesiodistal Width of Maxillary Anterior Teeth in Thrissur, Kerala, Indian Population.

Aims and Objectives:The aim of this study was to assess the validity of interalar distance as an aid in maxillary anterior teeth selection in Thrissur, Kerala, Indian population. The study also evaluated whether interalar distance and maxillary anterior teeth undergo any changes as age increases in this population and whether there is a gender difference in these parameters in this population.Materials and Methods:A study was planned on 1200 participants in Thrissur Municipal Corporation area, Kerala, India, with the aim of checking the validity of interalar distance as a successful aid in maxillary anterior teeth selection. The collected data were analyzed using SPSS version 21.0. Mean standard deviation and 95% confidence intervals were estimated. Student's t-test was used for comparison between gender and two age groups such as 18–25 and 40–50 years. One-way ANOVA analysis was done for combined effects.Results:The study showed that there is a high statistical significance between the interalar distance and the mesiodistal width of six maxillary anterior teeth in females (P < 0.01) and no significance in males.Conclusion:The study concluded that, within the population evaluated, there was a high significant correlation between interalar distance and the mesiodistal width of six maxillary anterior teeth in both males and females. Both interalar distance and mesiodistal width of maxillary anterior teeth showed a significant increase in size as age increases. There was a significant increase in size difference for males compared to females in relation to interalar distance and not for mesiodistal width of maxillary anterior teeth.

Odontometry and skull anthropometry: A possible tool for stature estimation using minimum armamentarium

Introduction: In the Asia Pacific region, because of variation in topography and climatic conditions, India is a disaster-prone country. The identification of an individual is one of the most important aspects of forensic medicine. There are different methods for identification of a person's age and gender. However, there are relatively fewer methods to estimate the stature of an individual. Stature correlation to skull and jaw dimensions is less frequently reported. The aim of the study is to investigate the relationship between height of the person and diameter of the head (DH) and circumference of the head with the combined mesiodistal (MD) width of maxillary anterior teeth using minimum and easily available armamentarium. Materials and Methods: Fifty model casts of students were considered to measure the MD width of the anterior teeth along with the circumference of the head and DH (distance from glabella to inion) with the help of a nonstretchable measuring tape. Heights of the students were recorded in inches. All the findings were tabulated and statistically analyzed. Observations and Results: When combined MD width of the maxillary anterior teeth was plotted against height, a statically significant correlation was seen. When head circumference was plotted against height, a higher correlation was seen. When two measurements were added and plotted against height, improved elevated correlation was seen. Similarly, when the MD width was added to circumference of the head and DH, a greater correlation was observed. Conclusion: It can be safely concluded that with more data to prove the study, a formula can be drawn to estimate the height of the person using MD width of the anterior teeth, DH, and circumference of the head.

Evaluation of the role of skull anthropometry for complete denture teeth selection: A cross-sectional study.

Background:Success of complete denture treatment lies in the ability to make it indiscernible from the natural. The selection of the six maxillary anterior teeth is of utmost importance as it contributes most to denture esthetics. Although various techniques and methods to determine the width of maxillary anterior teeth and its relation to various body measurements were done, the simple technique of using circumference of head has been less documented, specifically for Indian population.Aims and Objective:The aim of this study was to determine whether a relationship exists between the widths of the upper six anterior teeth to head circumference and the objective was to decide whether head circumference can be used as a deciding criterion to select size of maxillary anterior teeth for Central Indian population.Materials and Methods:This study was done on 300 people who included 135 males and 165 females. The circumference of head (A) and the combined width of the six anterior maxillary teeth (B) were measured and the ratio of A: B was determined.Results:EPO Info software version 6 was used to derive the statistical analysis with unpaired Student's t-tests. In male students, the mean of the ratio between the head circumferences to the combined widths of the anterior maxillary teeth was 10.14:1. In female students, the mean of the ratio between the head circumferences to the widths of the anterior maxillary teeth was 10.09:1. The average circumference of head to mesiodistal width of six anterior teeth ratio was concluded to be 10.Conclusion:Within the limitations of this study, the results suggest that head circumference divided by 10 can be used to select a teeth set with the resulting value as the combined mesiodistal width of six anterior teeth. This can be used as a starting point for determining the width of the anterior maxillary teeth for edentulous patients, which can be further confirmed with the esthetic appearance and with other facial measurements.

An Innovative Method to Determine the Width of Maxillary Anterior Teeth with the Help of Measurements Obtained from the Master Cast

Analyse the correlation between the measurements made from the landmarks on the cast and the width of the anterior teeth in dentulous study subjects and assessed whether a similar correlation exists in edentulous condition. Measurements were made on the cast of dentulous and edentulous subjects. The measurements made were, from incisive papilla to the right hamular notch, from incisiv e papilla to left hamular notch and distance between two hamular notches. After measuring these distances, the predicted value was calculated by taking mean of these three distances. The actual value in both the groups was measured with a flexible ruler. The mean and standard deviation of both groups were calculated. Results were analyzed with correlation and regression analysis. The analysis showed that there was a positive correlation between actual and predicted values in both dentulous and edentulous group of study subjects (p-value <0.01). As the actual value increased in both the groups, the predicted value also increased. So the actual value can be derived with the help of predicted value which will be useful in selecting the proper tooth mold size of the maxillary teeth for edentulous patients. A positive correlation exists between the width of the maxillary teeth (actual value) and mean of the distance (predicted value) between the right hamular notch and incisive papilla, left hamular notch and incisive papilla and interhamular distance in dentate subjects. The results obtained from the present study will be helpful for selecting the proper teeth mold size along with other teeth selection methods. Further studies are required to derive a more scientific and reliable method for anterior teeth selection.
