Correlation between Skull width among Different Age Groups

Introduction: Human bone increases in both size and complexity during the growth period which lasts from conception upto until maturity at about 16 to 18 years. The skull width is increased from 105 mm to around 146 mm as the age is increased from 6 months to 20 years. At the age of around 20,both the mastoid thickness and skull width reached the plateau and thereafter a very little growth occur.To evaluate the correlation between skull width among different age groups .Materials And Methods: This study was done on 84 people in three different age groups which includes 40 people aged between 20 to 30, 23 people aged between 30 to 50 and 21 people aged above 50. sample population were selected using a convenient random sampling method to participate in the study. Bitemporal,bizygomatic, bigonial measurements were obtained with the help of spreading caliper. Bitemporal measurement is taken between the most lateral point on the temporal bone. Bizygomatic measurement is taken between the most lateral points on the external surfaces of the zygomatic arches. Bigonial measurement is taken between two points at the external angle of the mandible. The values were analyzed statistically. Kruskal-Wallis Test was done in SPSS 23.0 version.Results: In the present study it is found that the P-value of bitemporal width between different age groups is 0.003 < 0.005 .So, it is statistically significant. The P-value of bizygomatic width between different age groups is 0.319 > 0.005.So,it is not statistically significant.The P-value of bigonial width between different age groups is 0.640 > 0.005 . So, it is not statistically significant.Conclusion: In our present study we measured the width of the skull in three different age groups and found that bitemporal width varied significantly with ages when compared to bizygomatic and bigonial width.
