To assess and compare the mandibular intercanine width (ICW) of children at three stages of mixed dentition in children at Namakkal district.
An analytical cross-sectional study was conducted among 135 schoolchildren aged 7-11 years, with 45 children in each group. Group I included children with completely erupted permanent mandibular central incisors, group II included children with completely erupted permanent mandibular central and lateral incisors, and group III included children with completely erupted permanent mandibular central incisors, lateral incisors, and canines. Impressions were made in the mandibular anterior region, and study casts were prepared. Measurements of the mandibular ICW were taken using a digital vernier caliper.
The mean mandibular ICW after the complete eruption of permanent mandibular central incisors, lateral incisors, and canines was 23.7, 25.5, and 25.7 mm, respectively. There was a statistically significant difference in the ICW between the three groups ( < 0.001). tests showed that mandibular ICW was statistically significant between groups I and II and group III ( < 0.001). Linear regression analysis showed that age does not contribute to the changes in mandibular ICW.
The average mandibular ICW found can be a standard comparison for treatment planning in the western Tamil Nadu population. Mandibular ICW reaches its maximum after the eruption of permanent mandibular lateral incisors. Changes in mandibular ICW should be attributed to the eruption of permanent mandibular anterior teeth and not to the age of the child.

评估和比较纳马卡尔地区儿童混合牙列三个阶段的下颌尖牙间宽度(ICW)。
对135名7至11岁的学童进行了一项分析性横断面研究,每组45名儿童。第一组包括下颌恒中切牙完全萌出的儿童,第二组包括下颌恒中切牙和侧切牙完全萌出的儿童,第三组包括下颌恒中切牙、侧切牙和尖牙完全萌出的儿童。在下颌前部区域制取印模,并制作研究模型。使用数字游标卡尺测量下颌ICW。
下颌恒中切牙、侧切牙和尖牙完全萌出后的平均下颌ICW分别为23.7、25.5和25.7毫米。三组之间的ICW存在统计学显著差异(<0.001)。检验表明,第一组与第二组以及第三组之间的下颌ICW具有统计学显著性(<0.001)。线性回归分析表明,年龄对下颌ICW的变化没有影响。
所发现的平均下颌ICW可作为泰米尔纳德邦西部人群治疗计划的标准对照。下颌ICW在下颌恒侧切牙萌出后达到最大值。下颌ICW的变化应归因于下颌前恒牙的萌出,而不是儿童的年龄。
