Odontometric and Skull Anthropometric Parameters as a Forensic Tool in Stature Estimation: A Cross-sectional Analysis

ABSTRACTBackgroundThe aim of the study was to evaluate the relation between height of an individual with the circumference of skull and combined mesiodistal width (CMDW) of the permanent maxillary anterior teeth in forensic and medicolegal investigations.Materials and methodsIn this study, 100 persons were evaluated. Mesiodistal widths of the permanent maxillary anterior teeth and height and circumference of the skull were measured. Linear regression analysis was used for the known heights of the combined data and data for males and females against the odontometric and anthropometric variables.ResultsHighly significant correlation was observed between height and other parameters for combined data and data for males. There was statistically significant difference between equation relating height to the CMDW of the maxillary anterior teeth and equation relating height to head circumference.ConclusionIt can be stated that the skull with teeth may provide accurate clues to stature from an individual's fragmentary remains and thus provide a reliable method of estimation of height from skeletal remains during forensic investigations.Clinical significanceOdontometric parameters along with regression equations may be used as a supplementary approach for stature estimation, especially in situations of unavailability of extremities. In the advancement of field of forensic odontology, skull anthropometry including maxillary extent, mesiodistal dimension of anteriors, and circumference of the skull are beneficial for stature estimation.How to cite this articleGondivkar SM, Gadbail AR, Vedpathak PR, Sarode S, Sarode G, Mankar M, Patil S.

Evaluation of the Current Techniques and Introduction of a Novel Approach for Estimating Maxillary Anterior Teeth Dimensions

Several techniques and methods have been proposed to estimate the anterior teeth dimensions in edentulous patients. However, this procedure remains challenging especially when preextraction records are not available. Therefore, the purpose of this study is to evaluate some of the existing extraoral and intraoral methods for estimation of anterior tooth dimensions and to propose a novel method for estimation of central incisor width (CIW) and length (CIL) for Saudi population. Extraoral and intraoral measurements were recorded for a total of 236 subjects. Descriptive statistical analysis and Pearson's correlation tests were performed. Association was evaluated between combined anterior teeth width (CATW) and interalar width (IAW), intercommisural width (ICoW) and interhamular notch distance (IHND) plus 10 mm. Evaluation of the linear relationship between central incisor length (CIL) with facial height (FH) and CIW with bizygomatic width (BZW) was also performed. Significant correlation was found between the CATW and ICoW and IAW (p-values <0.0001); however, no correlation was found relative to IHND plus 10 mm (p-value = 0.456). Further, no correlation was found between the FH and right CIL and BZW and right CIW (p-values = 0.255 and 0.822). The means of CIL, CIW, incisive papillae-fovea palatinae (IP-FP), and IHND were used to estimate the central incisor dimensions: CIL = FP-IP distance/4.45, CIW = IHND/4.49. It was concluded that the ICoW and IAW measurements are the only predictable methods to estimate the initial reference value for CATW. A proposed intraoral approach was hypothesized for estimation of CIW and CIL for the given population. Based on the results of the study, ICoW and IAW measurements can be useful in estimating the initial reference value for CATW, while the proposed novel approach using specific palatal dimensions can be used for estimating the width and length of central incisors. These methods are crucial to obtain esthetic treatment results within the parameters of the given population.

Analysis of the width ratio and wear rate of maxillary anterior teeth in the Korean population.

PURPOSEThe purpose of this study was to compare the width ratio of maxillary anterior teeth according to age in the Korean population and to evaluate the maxillary central incisor width-to-length (W/L) ratio, given differences in age and gender.MATERIALS AND METHODSNinety-three Korean adults were divided into 3 groups (n = 31) by age. Group I was 20 - 39 years old, Group II was 40 - 59 years old, and Group III was over 60 years of age. After taking an impression and a cast model of the maxillary arch, the anterior teeth width ratio and central incisor W/L ratio were calculated from standard digital images of the cast models using a graph paper with a digital single lens reflex (DSLR) camera. The calculated ratios were compared among all groups and central incisor W/L ratio were analyzed according to age and gender. All comparative data were statistically analyzed with one-sample t-tests, one-way ANOVAs with Tukey tests, and independent t-tests.RESULTSNo significant differences in maxillary anterior teeth ratios were found among the age groups. The maxillary central incisor W/L ratios in Group III were the greatest and were significantly higher than those in the other groups. The central incisor W/L ratio of men was higher than that of women in Group II.CONCLUSIONMaxillary anterior teeth width ratios were similar in all age groups in the Korean population. The maxillary central incisor was observed as worn teeth in the group over 60 years of age, and a significant difference between genders was found in 40 to 50 year olds.

Determination of proportional relationships between maxillary intercanine distance and various facial dimensions: A cross sectional study

The study was conducted on 231 subjects (101 males and 130 females) ranged from 15 years to 69 years in age, with all natural upper anterior teeth present in mouth having no caries, severe attrition, erosion, fracture or restorations were selected. Intercanthal distance (ICthD), intermedialcanthal distance (IMCthD), interpupillary distance (IPD), interalar width (IAW ), inter lip commissural distance (ICmD) and maxillary Intercanine distance from tip to tip (ICD) were measured with a venire caliper with an accuracy of 0.01 mm. Obtained data was entered into Microsoft excel program and various statistical calculations and tests were applied to find out correlation between above mentioned various facial measurements and maxillary intercanine distance in male and female subjects. The statistical results of this study showed that there was positive correlation between intercanthal distance and maxillary intercanine distance in both male and female subjects. Other facial measurements showed no statistically significant correlation with maxillary intercanine distance. Suggesting that the intercanthal distance can be used as a preliminary method to determine the width of the maxillary anterior teeth while constructing complete denture in edentulous patients.

Evaluation of widths of maxillary anterior teeth and their relation to the golden proportion in the southwestern part of Saudi Arabia

Background: With available esthetic dental materials in dentistry, satisfactory restoration of anterior teeth is possible. However in addition to the material aspect, the size and form to be given to the maxillary teeth assumes great significance. Aims: The aim of this study was to evaluate the existence of golden proportion in the widths of maxillary anterior teeth. Methods: This study was conducted with 30 male and 30 female students studying in the College Of Dental Sciences and Hospital, Jazan, Saudi Arabia. The students were screened for the fulfillment of selection criteria, Alginate impressions were taken and dental casts of maxillary arches made. The widths of anterior central incisors, lateral incisors and canines were measured using a digital caliper. The existence of golden proportion was investigated in the width ratios of the maxillary anterior teeth. Results: Comparison of perceived width ratios of lateral to central and canine to lateral with the golden proportion of 0.618 was carried out. In males the results showed that while the mean width ratio for the lateral to canine corresponded to the golden proportion, the lateral to central ratio did not correspond to the golden proportion. In females, the central to lateral ratio was in accordance with the golden proportion but not the canine to lateral ratio. Conclusion: Golden proportion was found to exist in the mean width ratios of canine-lateral teeth in males and in the mean width ratio of maxillary central and lateral teeth in females. Keywords: Golden proportion, anterior teeth, esthetic dentistry, canine-lateral width- ratio

Evaluating Recurring Esthetic Dental Proportion (RED) and Golden Proportion in Natural Dentition

Background: The width ratio of teeth is an important factor in dental and facial esthetics. The Golden proportion (62%) and the recurring esthetic dental proportion (RED) are two theories in this field that have been suggested to create harmony among anterior teeth. These have rarely been studied among the Iranian population. Objectives: The aim of this study was to evaluate the Golden proportion and RED proportion in students, staff, and patients of Shahed dental school. Patients and Methods: This study was conducted with 116 subjects in Shahed dental school photographs of the subject’s anterior teeth were taken from the frontal view. The perceived width ratios of canine to lateral incisor and lateral incisor to central incisor were calculated. In this study, the Golden proportion was evaluated within the range of 0.55 – 0.64. To evaluate the existence of the RED proportion in each subject, the width ratio of canine to lateral incisor was compared with the width ratio of lateral incisor to central incisor. Results: The Golden proportion existed in 25% of the perceived width ratios of lateral incisor to central incisor, and 2.1% of the width ratios of canine to lateral incisor in natural dentition. The RED proportion existed in 18.5% of subjects, and the most recurring proportion was 0.73 in these subjects. Conclusions: The Golden proportion and the RED proportion cannot be used as constant proportions to create a harmonious proportion throughout the width of maxillary anterior teeth.

Preferences of Lay Persons and Dental Professionals Regarding the Recurring Esthetic Dental Proportion.

This study evaluated the preferences of dental professionals and lay persons with respect to the Recurring Esthetic Dental (RED) Proportion, an objective mathematical tool used in treatment planning the "apparent" widths of maxillary anterior teeth. Stock dentofacial and facial images of a prototypical smiling male and female were digitally altered to demonstrate five different RED proportion relationships (0.62, 0.65, 0.70, 0.75, and 0.80). Four sets of the five altered images were presented to dental professionals and lay persons using a web-based survey site. The professional group included dentists and dental laboratory technicians. The lay group included anyone without previous dental education or experience. Study participants were asked to rank each series from most to least esthetic and their preferences were extracted from the data. Preference data from the five RED proportion relationships was consolidated into two categories: a narrow group including 0.62, 0.65, and 0.70 and a broad group including 0.75 and 0.80. Analysis shows that the level of professional training or experience does not play a significant role in the RED proportion preferences of study participants. Only in the prototypical male facial views was there any significant difference between professional and lay groups. For that view, a greater percentage of the layperson group preferred the narrow RED proportions. However, for the male dentofacial views that difference disappeared and both participant groups showed a slight preference for the broad proportion category. This may be due to the traditional esthetic stereotype for males to have broader, more vigorous appearing anterior teeth. For the prototypical female images, all participants expressed a clear, statistically significant preference for the narrower RED proportions in both full face and close up views. Based on the results above, dental professionals who are developing a treatment plan should attempt to utilize a RED proportion ≤ 0.70 for both male and female patients. The RED proportion is an objective numeric tool for relating the apparent widths of maxillary anterior teeth. It may be used by dental professionals to help diagnose and develop an optimal esthetic treatment plan. This paper offers insight into whether there are specific RED proportions that are preferred, whether there is a difference in preference when considering the male or female smile and whether professional educational training changes those preferences.

A comparative study to find out the relationship between the inner inter-canthal distance, interpupillary distance, inter-commissural width, inter-alar width, and the width of maxillary anterior teeth in Aryans and Mongoloids.

BackgroundOne of the most confusing and difficult aspects of complete denture prosthodontics is the selection of appropriately sized maxillary anterior denture teeth. Various guidelines have been suggested for determining the size of anterior teeth, but different opinions have been reported regarding their significance. In the study reported here, the relationships between facial measurements and the width of maxillary anterior teeth in two ethnic groups, namely Aryans and Mongoloids, were determined.ObjectiveThe aims of the study were to determine the inner inter-canthal distance (ICAD), inter-pupillary distance (IPD), inter-commissural width (ICOW), inter-alar width (IAW), and the combined width of maxillary anterior teeth (CW) in Aryans and Mongoloids and to determine the relationships between these measurements.Materials and methodsImpressions of the teeth of 170 dentulous subjects (85 males and 85 females) were made with alginate then Type IV gypsum product was poured in. Measurements of the cast maxillary anterior teeth at their widest dimension (contact areas) were made with the Boley gauge. ICAD, IPD, ICOW, and IAW distances were also measured with a Boley gauge.ResultsFor all 170 subjects, 85 Aryans and 85 Mongoloids, Pearson’s correlation coefficient (r) for IAW, IPD, ICOW, ICAD, and CW was calculated. In Aryans, highly significant (P<0.001) but weak correlations were found between CW and IAW, IPD, and ICOW. In Mongoloids, a highly significant (P<0.001) and weak correlation was found only between CW and IPD.ConclusionWithin the limitations of this study, the results suggest that the IAW, IPD, and ICOW for Aryans and IPD for Mongoloids can be used as a preliminary method for determining the width of the maxillary anterior teeth in edentulous patients.

Determination of stature from combined maxillary anterior teeth and head dimensions among the Efik and Ibibio of South-South Nigeria

Background: Studies on human identification by stature from combined width of maxillary anterior teeth and head dimensions have been carried out for forensic reasons. Materials and Methods: Body height, head circumference, head length, and width were measured in centimeter. Mesiodistal crown widths of central and lateral incisors, as well as canines of both sides, were also measured in centimeter. Statistical Analysis: Statistical analysis was carried using descriptive statistics, t-test, linear multiple regression analyses where P ≤ 0.05 was considered statistically significant. Results: In general, body height, head dimensions, and combined width of maxillary anterior teeth showed males had significantly higher values than females (P < 0.05). In the majority of data studied, the correlations between stature and head dimensions; stature and combined teeth dimension were statistically significant (P < 0.05). Coefficients of correlation were very low and reliability of the models were on the low side in the majority of the data studied. Conclusion: Based on the poor reliability of the models, these parameters can be employed only as supportive tools in stature estimation using regression analyses.

An Analysis of the Correlation between Mesiodistal Width of the Maxillary and Mandibular Anterior and Posterior Teeth in Iranian Population

Background and objective: Many authors have emphasized the difficulty of choosing suitable replacement teeth for edentulous patients and arranging these teeth in a natural way. In dentures, mesiodistal width of anterior teeth is the most important factor, because complete denture will not be able to provide a real appearance if artificial teeth are too small. For obtaining proper occlusion, maxillary and mandibular teeth must be proportional in size.. The purpose of this study is to determine correlation between the average mesiodistal width of posterior teeth and anterior teeth. Materials and methods: The sample consisted of 40 pairs of study casts of both jaws with normal occlusion (50% male and 50% female; aged 18-26). The mesiodistal width was measured directly on plaster models by use of a digital caliper (Mitutoyo, Tokyo, Japan) at the widest level of proximal contact area of the teeth. Measurements were repeated 1 day and 1 week later. Data was analyzed using SPSS 10 (Statistical Package for Social Sciences SPSS Inc., Chicago, IL). Mean and standard deviation values were calculated for each variable. Comparisons between female and male samples were made for each variable using Student's t-test. Results: The mean value for the mesiodistal width ratio of upper anterior to posterior sextant was calculated for female and male samples (1.38 ± 0.1 and 1.36 ± 0.07m respectively). The mean ratio for mesiodistal width of lower anterior to posterior sextant was calculated for female and male samples (1.00 ± 0.05 and 1.02 ± 0.05, respectively). Conclusions: the ratio of mesiodistal width of anterior teeth to posterior teeth can be used as a guideline for choosing correct artificial teeth for partially edentulous patients.

Evaluating the reliability of the interalar width and intercommissural width as guides in selection of artificial maxillary anterior teeth: A clinical study

Objective: Oral rehabilitation of a completely edentulous patient is essential to improve the patients self-esteem and self-confidence through the fabrication of conventional or implant supported overdentures. To achieve this, there is a need to restore the natural appearance of the patient through appropriate anterior tooth selection which requires reliable guidelines. Thus, the objective of this study was to determine the correlation and evaluate the reliability of the interalar width to intercanine distance and intercommissural distance to the distal aspects of the canines in the selection of maxillary anterior teeth. Materials and Methods: Two-hundred individuals who satisfied the inclusion and exclusion criteria were selected. The four parameters such as interalar width, intercanine distance, intercommissural width, and distance between distal aspects of canines were measured. The data obtained were statistically analyzed. Results: The results revealed that the mean values for interalar width and intercanine distance in males were 3.852 and 3.538 cm, respectively, and in females, it was 3.396 and 3.402 cm, respectively. In addition, the mean values for intercommissural width and distance between the distal aspects of canines were 4.921 and 3.913 cm in males, respectively. In females, it was 4.590 and 3.740 cm, respectively. In males and females, the correlation between interalar width and the difference between the intercanine distance and interalar width is statistically highly significant (in males r = 0.707, in females r = 0.619). Correlation of difference of intercommissural width and the distance between the distal aspects of the canines with the average of intercommissural width is statistically significant (in males r = 0.777, in females r = 0.712). Conclusion: A correlation was observed between the interalar distance and the intercanine distance and also between the intercommissural distance and the distance between the distal aspects of canines. Clinical Relevance To Interdisciplinary Dentistry It is the dentists' responsibility to preserve the natural dignity of advancing age while fabricating a complete denture prosthesis, with appropriate and careful selection and arrangement of teeth As it is difficult to determine the dimensions of the maxillary anterior teeth for an edentulous patient when preextraction records are not available, other guidelines must be taken into consideration and the development and implementation of an esthetic proforma to guide the dentist and patient may be essential One area of prime concern may be to determine correlations and relationships between interalar width and intercommissural width with the mesiodistal width of upper anterior teeth which can be interpreted as a useful guide in clinical practice.

The selection of maxillary anterior teeth width in relation to facial measurements

Objectives: This clinical study was carried out to determine the relationships between maxillary anterior teeth width [canine arc distance, central incisor width], and certain horizontal facial parameters which include: [(Interzygomatic, inner and outer canthus and interpupillary) distances, and (interalar, mouth and philtrum of upper lip) widths], to be used as a guide to selection of the maxillary anterior teeth width.&#x0D; Materials and Methods: The facial measurements were taken directly from (60) under-graduate students in age range (19-24) years old by using an electronic digital vernier caliper. While canine arc distance and central incisor width were measured indirectly on the casts made from impressions of the selected subjects using flexible millimeter ruler. The collected data were analyzed and correlated using statistical package SPSS version 20.&#x0D; Results: The mean value of all the parameters measured were significantly higher in males than female, for male just a significant correlation was found between canine arc distance and mouth width, CARCD =0.994×MW, while for females significant correlation was found between canine arc distance mouth width, inner and outer canthal distance, and interpupillary distance, but the most significance relation was with the mouth width, CARCD=1.036×MW, and central incisor width was significantly correlated with, mouth width, CIW = MW ÷6.15, CIW = MW ×0.16. &#x0D; Conclusions: This study demonstrated that certain horizontal facial parameters could be used as a guide in maxillary anterior teeth width selection to achieve an optimal esthetic result for each gender.

Selecting maxillary anterior tooth width by measuring certain facial dimensions in the Kurdish population

Statement of problemOne of the most difficult aspects of complete denture fabrication is selecting appropriately sized maxillary anterior teeth that will harmonize with the face. There are no generally accepted or naturally observed principles to guide dentists in this selection. PurposeThe purpose of this study was to determine whether a relationship exists between various facial measurements and the different single or combined mesiodistal widths of maxillary anterior teeth in a Kurdish population. Material and methodsA total of 65 Kurdish dental students participated in this study. Two standardized digital photographs of the face (relaxed and smiling capture) were recorded. The interpupillary distance (IPD), inner canthal distance (ICD), interalar distance (IAD), and width of the 2 central incisors were determined by Image J software. The mesiodistal width and the combined straight-line width of the centrals, laterals, and canines were measured directly from the casts of the participants with digital calipers. A simple linear regression and the Pearson correlation coefficient were used to investigate the relationship between the particular facial measurement and the widths of the anterior teeth (α=.05). ResultsSignificant correlations existed between the IPD and different tooth measurements; the highest was with the mean width of the canines (r=0.55). The proposed proportion between the IPD and the central incisor width was 6.93. The golden proportion of the ICD to the width of the central incisors and of the IAD to the straight-line width of the 6 anterior teeth could be used as a dependent parameter in Kurdish men. ConclusionsThe IPD can be used to predict the width of anterior teeth in both sexes. In men, the width of the central incisors may be estimated from the ICD and the straight-line width of the 6 anterior teeth from the IAD.

Morphological features of maxillary anterior teeth in a sample of Chinese population

The purpose of this study is to investigate the morphological features of maxillary anterior teeth in the Chinese population. The width-to-height ratios of these teeth and the width proportions of the central incisor and canine to the lateral incisor were calculated on the casts of 101 Chinese individuals with normal occlusion. The mean width in the sample was taken as the given lateral incisor width. The given central incisor width and canine width were decided according to the width proportion relationship. The maxillary anterior teeth with the given width were placed in the dentitions with three different types of arch forms, and the esthetic effect from the front view was analyzed. The results showed that the width-to-height ratios for the central incisor, lateral incisor, and canine were 87.75% (SD=8.31%), 84.02% (SD=7.74%), and 86.99% (SD=7.80%), respectively. The width-to-width proportions of the central incisor to lateral incisor and canine to lateral incisor were 1.19% (SD=0.09) and 1.13% (SD=0.09%), respectively. With the given maxillary anterior tooth width, the golden ratio or other recurring proportion between the teeth is not obtained in any arch form from the front view. These results lead to the conclusion that Chinese maxillary anterior teeth display a square-like form with rather high width-to-height ratios. There is the possibility that there is no golden ratio or other recurring proportion in the width relationship between the maxillary anterior teeth of Chinese individuals.

The relationship between innercanthal dimension and interalar width to the intercanine width of maxillary anterior teeth in central Indian population.

Statement of Problem:Selection of proper sized maxillary anterior teeth is one of the difficult clinical steps in complete denture esthetics. Several studies have been reported to establish methods of estimating the combined width of maxillary anterior teeth.Purpose:The aim of this study was to determine whether a relationship exists between the innercanthal distance (ICD) and interalar width (IAW) with the combined width of maxillary anterior teeth.Material and Methods:The maxillary anterior teeth of 600 adult subjects were examined. ICD was measured between the median angles of the palpebral fissure. IAW was measured between the ala of the nose at their widest point. The mean combined width of the maxillary anterior teeth was determined intraorally at their widest dimension. Pearson's correlation coefficients were calculated to determine the relationship between ICD, IAW and the combined width of maxillary anterior teeth (α =0.05).Results:Although the Pearson correlation coefficients were relatively small, a significant relationship existed between innercanthal dimension and IAW (P < 0001).Conclusion:Within the limitations of this study, the results suggest that ICD and IAW cannot be used as a preliminary method for determining the width of the maxillary anterior teeth for edentulous patients.

The Selection of Maxillary Anterior Teeth Width in Kashmiri Population

Introduction: Determining the width of maxillary anterior teeth is a difficult aspect in complete denture fabrication. The width of maxillary anterior teeth is determined by taking various anatomical landmarks on the face as a guide, such as the interpupillary, interalar, intercommissure and interzygomatic distance, etc. The present clinical study was carried out to evaluate the relationships between maxillary anterior teeth measurements (canine to canine and central incisor width) and various horizontal facial parameters. Materials and methods: The facial and dental measurements were obtained directly from 60 Kashmiri undergraduate dental students by using vernier calliper and dental floss. Result: Correlation analysis was done using Pearson’s correlation analysis and it was determined that the incisor width and canine to canine distance show positive correlation with some of the facial measurements. Conclusion: This study inferred that while most of the measurements showed a positive correlation with the incisor width and canine width in the different face forms none of them were found to be significant.

Determination of mesiodistal width of maxillary anterior teeth using inner canthal distance

BackgroundSelection of appropriately sized maxillary anterior teeth is one of the important aspects of complete denture prosthodontics. In the past several methods have been proposed, but little consensus on an effective method for anterior teeth selection has been reached. Inner canthal distance is one of the reliable anatomic dimension that may provide a valid approach to anterior teeth selection. This study was aimed to ascertain the co-relation between inner canthal distance (ICD) and combined mesiodistal width of maxillary anterior teeth. MethodThis study was conducted in Army Dental Centre (R & R) Delhi Cantonment between Aug 2006 to Mar 2008. Eight hundred dentate Indian subjects of four different ethnic group; Such as Rajputs, Marathas, Sikh and Tamilian. 100 males and 100 females from each race under the age group of 18–30 years formed the subjects of study. The ICD and mesio-distal width of maxillary anteriors were measured using Digital Vernier Caliper. The Data obtained was statistically analyzed. ResultsA consistent ratio of 1.61 was found between ICD and combined mesiodistal width of maxillary anteriors in all four ethnic group. The mean value showed no statistically significant difference between sex. The variation in the ratio between the ethnic groups was negligible. ConclusionThe findings of the study indicated that, to select the combined mesiodistal width of maxillary anterior teeth, ICD of the required patient should be multiplied by 1.61. This ratio was consistent with all the four ethnic groups irrespective of sex.

Correlation between Combined Width of Maxillary Anterior Teeth, Interpupillary Distance and Intercommissural Width in a Group of Indian People

ABSTRACT Purpose The objective was to evaluate the correlation between the width of distal surface of canine (CWC), interpupillary distance (DMP) and intercommissural width (DCM) in a group of central Indian people. Materials and methods A total of 540 central Indian subjects (277 males and 263 females) aged 19 to 30 years were selected. DMP and DCM were measured on subject's face using digital vernier caliper [Mitutoyo (UK) Ltd.] with precision of 0.01 mm. Irreversible hydrocolloid impression of the upper arch was taken, and a cast was poured with dental stone. The CWC measurements were done on these casts with the help of a dental floss fixed between the distoproximal contacts of upper canines using a dental tape. Spearman's correlation test was used to determine the correlation between the three variables studied. Results The results revealed that the correlation between CWC-DMP was 0.015 and CWC-DCM was 0.031. The correlation showed negative values when compared between the sexes. Also, the proportions were calculated: DMP/CWC and DCM/CWC for the whole sample and for the sexes found no statistical significance (p &gt; 0.05). Conclusion The results of this study suggest that the examined interpupillary distance and intercommissural width cannot be considered reliable guidelines in the selection of artificial upper frontal teeth. However, they may be used as a useful additional factor combined with other methods for objective teeth selection in complete denture therapy.
