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 -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.
背景
全口义齿治疗的成功在于使其与天然牙难以区分。上颌六颗前牙的选择至关重要，因为它对义齿美观的贡献最大。尽管已经采用了各种技术和方法来确定上颌前牙的宽度及其与各种身体测量值的关系，但使用头围的简单技术记录较少，特别是针对印度人群。
目的
本研究的目的是确定上颌六颗前牙的宽度与头围之间是否存在关系，目标是确定头围是否可以用作选择印度中部人群上颌前牙大小的决定标准。
材料和方法
本研究对300人进行，其中包括135名男性和165名女性。测量头围（A）和上颌六颗前牙的总宽度（B），并确定A:B的比例。
结果
使用EPO Info软件版本6进行非配对学生t检验的统计分析。在男学生中，头围与上颌前牙总宽度之比的平均值为10.14:1。在女学生中，头围与上颌前牙宽度之比的平均值为10.09:1。得出头围与六颗前牙近远中宽度之比的平均值为10。
结论
在本研究的局限性内，结果表明头围除以10可用于选择一组一组牙齿，所得值作为六颗前牙的近远中总宽度。这可以作为确定无牙患者上颌前牙宽度的起点，可通过美观外观和其他面部测量进一步确认。
