摘　　要：目的:介绍一种新的牙齿记录法,以达到简便而准确地描述和记录牙齿的目的。方法:T或t作为记录牙齿的标识字符,T代表恒牙,t代表乳牙。用数字1～8和1～5从牙弓中线向远端对恒牙和乳牙编号。用"字母加数字"的方式对恒牙和乳牙、上颌牙和下颌牙、前牙和后牙以及牙位进行记录。结果:恒牙标记为T1～T8,乳牙标记为t1～t5。上、下颌恒牙分别标记为UT1～UT8和LT1～LT8。上、下颌乳牙分别标记为Ut1～Ut5和Lt1～Lt5。前牙、前磨牙和磨牙分别标记为T(1-3)、T(4、5)和T(6-8)。乳前牙和后牙分别标记为t(1-3)和t(4、5)。恒牙牙位用上下标牙位记录法或"UR、UL、LR、LL"加"T1～T8"标记。乳牙牙位用上下标牙位记录法或"UR、UL、LR、LL"加"t1～t5"标记。结论:新的牙齿记录法能简便而准确地标记牙齿、上下颌牙齿、前牙和后牙以及牙位。AIM： To introduce a new system for describing and recording teeth simply and accurately. METHODS： T and t were considered as identification characters of teeth to be recorded. T represented permanent teeth and t represented deciduous teeth. Permanent teeth and deciduous teeth were numbered with digits 1 - 8 and dig- its 1 - 5 respectively from the midline posteriorly. Permanent teeth and deciduous teeth, maxillary teeth and mandibular teeth, anterior teeth and posterior teeth, and the location and name of tooth in the dentitions were recorded by the form of ＂letters ＋ numbers＂. RESULTS ： Permanent teeth were denoted as T1 - T8 and deciduous teeth as tl - 15. Perma- nent maxillary teeth and mandibular teeth were denoted as UT1 - UT8 and LT1 - LT8 respectively. Deciduous maxillary teeth and mandibular teeth were denoted as Utl - U15 and Lt1 ~ Lt5 respectively. Permanent anterior teeth, permanent premolars and permanent molars were denoted as T （ 1 - 3 ） , T （ 4, 5 ） and T （ 6 - 8 ） respectively. Deciduous anterior teeth and deciduous posterior teeth were denoted as t（ 1 -3）and t（4, 5 ）respectively. The location and name of tooth in the permanent dentition were denoted by superscript - subscript tooth notation system or by＂ UR or UL or LR or LL＂ ＋ ＂TI ~ T8＂. The location and name of tooth in the deciduous dentition were denoted by superscript- subscript tooth notation system or ＂UR or UL or LR or LL＂ ＋ ＂t1 -t5＂. CONCLUSION： Teeth can be denoted by this new system conveniently and accurately.
