Database E.4 Individual Records of Measurements of Permanent Dentitions in Adolescents and Adults

This database is part of Appendix E, from Ban Chiang, a Prehistoric Village Site in Northeast Thailand, Volume 1: The Human Skeletal Remains (tDAR ID #: 376592). Database E.4 contains metric observations (Measurements of Permanent Dentitions in Adolescents and Adults) by individual burial excavated from the BC and BCES locales at Ban Chiang, Thailand.

Coding information is pasted at the bottom of this abstract, and can also be downloaded as a .txt document at tDAR ID#:

SPECID = Individual Burial Number
First number is excavation locale
1 = BC, 1974 excavation
2 = BCES, 1975 excavation

followed by two spaces and then the burial identification number.
Example: 1 14 is BC Burial 14

SEX = Sex of individual

AGE
ADOL = Adolescent (15-20 years)
YG ADULT = Young Adult (20-35 years)
MIDAGE = Middle-aged Adult (35-50 years)
OLD = Old Adult (50+ years)
ADULT = Adult (20-50+ years)

SITE = Site of excavation

YEAREXAM = Year burial was examined

INSTCODE = Institution where burial was examined
UHM = University of Hawaii at Manoa

Diameters measured to the nearest tenth of a millimeter. Cross-sectional areas calculated by computer to two places to the right of the decimal point.

Each of the variables is composed of three parts:
First Part:
U = Upper; L = Lower
R = Right; L = Left
Second Part:
M3 = Third molar
M2 = Second molar
M1 = First molar
P4 = Fourth premolar
P3 = Third premolar
C = Canine
LI = Lateral incisor
CI = Central incisor
Third Part:
MD = Mesio-distal diameter
BL = Buccal-lingual diameter
CX = Cross-sectional area

Example: URM3MD is the upper right third molar mesio-distal diameter.

TS3 = Individual's tooth summary

本数据库隶属于泰国东北部史前村落遗址班清（Ban Chiang）的附录E，出自《第一卷：人类骨骼遗存》（tDAR编号：376592）。数据库E.4收录了泰国班清BC与BCES发掘点出土的各墓葬个体的度量观测数据——即青少年与成人恒牙列测量数据。

编码信息附于本摘要末尾，也可通过tDAR编号下载为.txt文档：

SPECID（个体墓葬编号）：
第一位数字代表发掘区域：
1 = BC，1974年发掘区域
2 = BCES，1975年发掘区域
其后跟随两个空格与墓葬编号。
示例：1 14 即BC区域墓葬14

SEX：个体性别

AGE（年龄分组）：
ADOL = 青少年（15~20岁）
YG ADULT = 青年成人（20~35岁）
MIDAGE = 中年成人（35~50岁）
OLD = 老年成人（50岁及以上）
ADULT = 成人（20~50岁及以上）

SITE：发掘遗址

YEAREXAM：墓葬检测年份

INSTCODE（检测机构代码）：
UHM = 夏威夷大学马诺阿分校

所有牙冠直径测量精确至0.1毫米，截面积通过计算机计算，保留小数点后两位。

各观测变量均由三部分构成：
第一部分：标识牙位的上下颌与左右侧：
U = 上颌；L = 下颌
R = 右侧；L = 左侧
第二部分：标识牙齿类型：
M3 = 第三磨牙（Third molar）
M2 = 第二磨牙（Second molar）
M1 = 第一磨牙（First molar）
P4 = 第四前磨牙（Fourth premolar）
P3 = 第三前磨牙（Third premolar）
C = 尖牙（Canine）
LI = 侧切牙（Lateral incisor）
CI = 中切牙（Central incisor）
第三部分：标识测量指标：
MD = 近远中径（Mesio-distal diameter）
BL = 颊舌径（Buccal-lingual diameter）
CX = 截面积（Cross-sectional area）

示例：URM3MD 即右上第三磨牙近远中径
