Methods: A right handed patient with cold stimulated dentinalgia of the first right maxillary bicuspid was selected to perform the fMRI study. Other tooth pulp disease and oral metal restoration were excluded.

BI of upper left first bicuspid was the highest, and the upper left incisor was the lowest.

左侧上颌中切牙的BI最小；左侧上颌第一前磨牙的BI最大；

Objective: To study the tooth size correlation between permanent cuspid and bicuspid group and other teeth groups in malocclusion.

Objective To find out the changes of the soft tissue profile in Guangdong women with Angle's I teeth uncovered by lips after extraction of 4 first bicuspid teeth and to evaluate its significance.

目的了解广东成年女性安氏Ⅰ类开唇露齿患者拔除4个第1双尖牙矫正后软组织侧貌变化情况，评价该类患者矫正后软组织变化的意义。

Objective To evaluate age-related changes in expression of HSP70 in odontoblasts of bicuspid teeth.

目的观察热休克蛋白（HSP）70在前磨牙成牙本质细胞表达的增龄变化特点。

Most of wedge-shaped defects were found at first bicuspid teeth.

楔状缺状发病率最高的是第一双尖牙；

Objective: To observe the restoration and healing effects of implantation of natural non organic bone ( NNB) in chronic periapical bone destruction of anterior teeth or bicuspid teeth.

目的：观察前牙、双尖牙慢性根尖周病变骨质破坏时，植入天然型无机骨（NNB）的修复与愈合效果。

Conclusion With respect to the protection of the anchorage of molar, it is more suitable for the palatal implant to connect with the first permanent molar than with the maxillary second bicuspid.

结论就保护磨牙支抗来说，种植体连接在上领第一性磨牙较之连接在上领第二双尖牙更加合适。

In addition, the changes of width between second bicuspid and mandibular molars showed statistical significances.
