Both upper and lower dental study models were collected from 30 boys (12 years old) and 30 girls (12 years old) with acceptable normal occlusion to understand the characteristics of the crown size, dental arch width and length such as (1) mesiodistal diameters of crown size from central incisor to first molar,(2) the width and length of dental arch and basal arch and (3) the morphology of dental arch form. After statistical analysis, data were compared with Japanese, Central and South American Indians and North American Caucasians from papers. The results were:(1) There was no statistical difference in teeth size between males and females, except the upper first molar of males was larger than that of females, lower central incisor of males was smaller than that of females.(2) The dimensions of dental arch of males were larger than that of females in general, especially such items as width and length of basal arch.(3) The crown size of Chinese male was in generally smaller than that of four other races, especially the upper canine, lower central incisor and first molar.
为了解住在台湾的中国人其牙齿的大小，齿列弓幅径及形态，为齿科人类学上的特微，以期能对儿童牙科，齿颚矫正科之临床及齿科基础医学能有所贡献，抽取12岁学童男女各30名共60名，可接受为正常咬合之上下颚齿列模型，测量其上下颚(1)左侧正中门牙到第一大臼齿共计12颗恒牙之牙冠近远心径，(2)齿列弓宽径、长径及齿槽基底宽径、长径，(3)齿列弓之形态，以上资料经统计分析作t-test检定，并与诸学者对日本人、北美白人、中美及南美印第安人人种的研究结果作检讨得知；(1)男女性恒牙的近远心径无明显差异，但男性上颚第大臼齿比女性者大，下颚正中门牙比女性者小；(2)男性的齿列弓幅径比女性者为大，尤以齿槽基底宽径及长径最显著；(3)国人男子的牙齿近远心径比其他四人种者为小，特别是国人的上颚犬齿，下颚正中门牙及第一大臼齿最小。

One of many factors contributory to development of periodontitis is an unerupted or abnormally erupted third molar and it may cause deep pocket formation and bony resorption at the distal side of adjacent second molar. It is also prone to result in periodontitis due to interdental food impaction and uneasy cleaning between the third molar and second molar.
在形成牙周炎的众多贡献因子中，其中因第三大臼齿萌发方向异常或萌发不全，可能造成第二大臼齿远心侧形成牙周囊袋和周围牙周骨头吸收；或第二及第三大臼齿间因缝隙口腔清洁不良而好犯牙周病。

In the treatment of impacted third molar, dental practioner and oral surgeon more often think about how to extract the third molar completely, but rarely consider to add some procedures such as distal wedge, alveoloplasty, guided tissue regeneration, and apically repositioned flap etc., to prevent 2nd molar from developing periodontitis. The latter procedures can reduce its accompanying deep pocket, to remove plaque and calculus on its diseased root surface.
在治疗阻生第三大臼齿，诊所执业医师和一般口腔外科医师较常会考虑怎样把阻生第三大臼齿完全拔除，但却较少考虑在拔除阻生第三大臼齿的同时做一些措施，像远心楔形手术，齿槽骨整形术，引导组织再生术和牙周办膜根向移动术等来预防第二大臼齿远心端形成牙周炎，或同时替第二大臼齿治疗深的牙周囊袋和去除其牙根表面的牙结石和牙菌斑。
