The Relationship Between Widths of Upper Anterior Teeth and Facial Widths

2016

The scope of the study was to determine the ratio between maxillary anterior teeth widths to width of facial proportions in a dental college in Karachi, Pakistan. The widths of facial proportions were determined using a Vernier Caliper. The widths of maxillary anterior teeth were measured intraorally using Boley’s gauge on a sample of 116 human subjects visiting the Diagnosis Department in Dr Ishrat-ul-Ebad Khan Institute of Oral Health Sciences, (DIKIOHS), Dow University of Health Sciences, Karachi, Pakistan. All readings were measured in millimeters. Pearson’s correlation test was applied and it showed no significant relation between width of central incisor and bizygomatic width (0.11). But a significant relationship was found between intercanine width and width of mouth (0.03), width of philtrum and mean width of central incisors (p=0.05), interalar width and intercanine width (p=0.00). Facial proportions solely do not provide a secure prototype in selecting maxillary anterior t...

A Comparison of Morphometric Parameters Observing Tooth Size Discrepancies and Archwidth Among the Indian and Iranian Population- a Pilot Approach

2016

BackgroundOrigin and the gender have a definitive role to play in the growth and development of an individual. The Bolton’s ratio and arch width parameters are such parameter which are taken into consideration while treating malocclusion. A definite relationship between the two arches is often hampered due to the discrepancy in the above mentioned parameters. There are definite differences in the developmental milestones between the males and females, the malocclusions also do show differences when these parameters are considered. The reports based on the differences in these parameters based on the malocclusion, gender and ethnicity altogether are scanty and hence this must be taken into consideration as a part of research which can help orthodontist to render better treatment understanding of these core concepts. Aims and objectives-The aims and objectives of the present study were to determine and compare the anterior and overall Bolton’s ratios and arch width between Iranian and...

Significance of Intercanthal Distance in the Selection of Width of Maxillary Anterior Teeth Size in Kashmiri Population: A Research

The selection of appropriate size of artificial teeth takes an important place in designing complete denture prosthesis. However, the standards or proportions commonly used as a guide have been developed mainly on Caucasian populations. Objectives: To investigate the relationship between intercanthal distance and two variables i.e. mesiodistal width of central incisors and combined width of six maxillary anterior teeth size in Kashmiri population. Materials and methods: This is a descriptive cross sectional study conducted on 200 subjects, (100 males -100 females), from Kashmiri population. The age range was from 18-55 years. The intercanthal distance was measured as the distance between the medial (inner) angles of the palpabral fissure. Mesiodistal width of the maxillary central incisors and combined width of six maxillary anterior teeth were recorded. An electronic digital caliper (Narex -Czechoslovakia), was used for all measurements. Data were analyzed using Person chi-square test. Results: For the sample population the ratio was 1:0.268 for the central incisors and 1:1.395 for six anterior teeth. Mean intercanthal distance was found to be 31.67. Conclusion: These results could be used as a helpful guide for initial selection of anterior teeth width in the Kashmiri population.

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

World Journal of Dentistry

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.

Prediction the widths of maxillary and mandibular canines and premolars from the widths of maxillary incisors and first molars (Iraqi study

Background: This study aimed to use the combined mesio-distal crowns widths of maxillary incisors and first molars as predictors to the combined mesio-distal crowns widths of maxillary and mandibular canines and premolars. Materials and methods: The sample included 110 Iraqi Arab subjects with an age ranged between 17-25 years and class I skeletal and dental relations. The crown widths of maxillary teeth and mandibular canines and premolars were measured at the largest mesio-distal dimension on the study casts using digital electronic caliper with 0.01 mm sensitivity. Pearson's correlation coefficient was used to determine the relation between the combined mesio-distal crowns widths of maxillary incisors and first molars and the combined mesio-distal crowns widths of maxillary and mandibular canines and premolars. Regression analysis was used to determine the equations that predict the widths of maxillary and mandibular canines and premolars. Paired sample t-test was used to compare between the actual and predicted mesio-distal crown widths. Results and Conclusions: The findings showed a non-significant difference between the predicted and actual mesio-distal crown widths; hence the combined mesio-distal widths of maxillary incisors and first molars can be used as predictors for the combined mesio-distal widths of maxillary and mandibular canines and premolars.
