Abstract

OBJECTIVES

To explore deciduous tooth crown dimensions in strabismic children and the relationship between the type of strabismus and tooth crown mesio-distal (M-D) and labio-lingual (L-L) size asymmetries.

MATERIAL

Dental casts at mixed dentition of 2159 Collaborative Perinatal Study black and white children were measured, 123 of them strabismic at 1 year of age, age ranging from 6 to 12 years.

METHODS

Directional and fluctuating asymmetries in antimeric teeth were explored in various types of strabismus having unilateral, bilateral or alternating expression. ANOVA and T-square test were used for size comparisons and calculated asymmetries were explored by comparing the variances and Pearson correlations.

RESULTS

Strabismus was associated with significant M-D size increase of deciduous maxillary canines in black boys and white girls, black girls had size reduction in their mandibular canine, but white boys were unaffected. Right side size dominance was found in the strabismic children in the lower second deciduous molar M-D dimensions and in the children with alternating strabismus in their upper deciduous canine M-D dimensions. Children with unilateral strabismus had random fluctuating dental asymmetry in their upper deciduous second molar L-L dimensions when compared with healthy normals. Higher left-right correlations were found in lower second deciduous molar dimensions in strabismic girls when compared with that in controls and in strabismic boys, suggesting better developmental canalization in female.

CONCLUSIONS

Asymmetries in the head area, such as promoted here in strabismic children, may have associations with asymmetries in the dentition, focusing the embryonal origins and timing of developmental processes.

摘要

目的

探讨斜视儿童乳牙冠尺寸,以及斜视类型与牙冠近远中(M-D)和唇舌向(L-L)尺寸不对称之间的关系。

材料

对2159名参与围产期协作研究的黑白儿童混合牙列期的牙模进行测量,其中123名儿童在1岁时患有斜视,年龄范围为6至12岁。

方法

在具有单侧、双侧或交替表现的各种斜视类型中,探讨对侧牙的方向性和波动性不对称。采用方差分析和T检验进行尺寸比较,并通过比较方差和皮尔逊相关性来计算不对称性。

结果

斜视与黑人男孩和白人女孩上颌乳尖牙的M-D尺寸显著增加有关,黑人女孩下颌尖牙尺寸减小,但白人男孩未受影响。在斜视儿童的下颌第二乳磨牙M-D尺寸以及交替性斜视儿童的上颌乳尖牙M-D尺寸中发现右侧尺寸占优势地位。与健康正常儿童相比,单侧斜视儿童上颌第二乳磨牙的L-L尺寸存在随机波动的牙齿不对称。与对照组和斜视男孩相比,斜视女孩下颌第二乳磨牙尺寸的左右相关性更高,表明女性发育的协调性更好。

结论

头部区域的不对称,如本研究中斜视儿童所表现的,可能与牙列不对称有关,这集中在胚胎起源和发育过程的时间上。
