Database E.2 Individual Records of Mandibular Measurements and Indices in 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.2 contains metric observations (Mandibular Measurements and Indices in 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

AGE
YG ADULT = Young Adult (20-35 years)
MIDAGED = Middle-aged Adult (35-50 years)
OLD = Old Adult (50+ years)
ADULT = Adult (20-50+ years)

SEX = Sex of individual

SITE = Site of excavation

YEAREXAM = Year burial was examined

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

Variables MANDLNTH through MONETHRE were recorded to the nearest millimeter

MANDLNTH = Mandibular length

INFMANDL = Inferior mandibular length

ALVEOLGT = Alveolar length

BICONDWH = Bicondylar width

MIDCONDW = Bicondylar articular breadth

CORONBTH = Bicoronoid breadth

BIGONIAL = Bigonial breadth

BICANBTH = Bicanine external breadth

FRMOLBTH = Bimolar-1 external breadth

THMOLBTH = Bimolar-3 external breadth

SYMPHYHT = Symphyseal height

MENFORHT = Mental foramen height

CANINEHT = Canine height

MOLARHT = Molar height

SYMPHYBH = Symphyseal breadth

MENFORBH = Mental foramen breadth

CANINEBH = Canine breadth

MOLARBH = Molar breadth

RAMUSHGT = Ramus height

RAMUSBTH = Ramus breadth

MANDNOTB = Mandibular notch breadth

CONDYLGT = Condyle length

CONDBTH = Condyle breadth

PMMOLARL = P3-M1 length

MONETWO = M1-M2 length

MONETHRE = M1-M3 length

The following are indices that were calculated by computer to four places to the right of the decimal point. During data conversion from mainframe to personal computer format, the indices were truncated to two places right of the decimal point--they were not arithmetically rounded.

MANINDEX = Mandibular index

GONINDEX = Gonio-condylar index

RAMINDEX = Ramus index

MANDROBX = Mandibular robusticity index
