Database NNT07 Codebook (web ver. 1.0) of Individual Records of Hypoplasias and Carious Lesions in Permanent Dentitions


     Explanation of Abbreviations and Codes

     SPECID = Individual Burial Number
         First number is excavation locale
             NNT1 = 1966 excavation
             NNT2 = 1968 excavation

         followed the burial identification number.
            Example: NNT1-014 is First Season NNT Burial 014

     AGE
	1 YG ADULT = Young Adult (20-35 years)
	2 MIDAGED = Middle-aged Adult (35-50 years)
	3 OLD = Old Adult (50+ years)
	4 ADOL = Adolescent (15-20 years)
	5 CHILD = < 15 years
    	6 INFANT = 0-1 years
    	7 ADULT = 20-50 years
    	8 SUBADULT =  <20 years


     SEX = Sex of individual, ?female coded as FEMALE, ?male coded as MALE

     SITE = Site of excavation

     YEAREXAM = Year burial was examined

     INSTCODE = Institution where burial was examined
         SIR = Siriraj Hospital, Mahidol University, Bangkok, Thailand
         UNL = University of Nevada, Las Vegas, USA

     These data follow the dental arcade beginning with the upper left third molar to the upper right third molar followed by the lower left third molar to the lower right third molar. There are 32 observations for each of the variables.

     For each field name, following the variable code (HYPO and CARI) is the designation for each tooth according to the following code.

     The first letter is the jaw location U = upper, L = lower;
     The second letter is the side R = right, L = left;
     The last letters are the tooth (i.e., M3 = third molar).

     HYPO = Hypoplasia
         0 = absent
         1 = linear horizontal defect
         2 = linear vertical groove
         3 = linear horizontal pitting
         4 = nonlinear pitting
         5 = single pit
         6 = color change

     CARI = Caries
         0 = absent
        1A = occlusal fissure
        1B = occlusal cusp
        1C = occlusal gross
        2A = interproximal mesial crown
         2B = interproximal distal crown
         3A = buccal crown
         3B = lingual crown
         4A = cemento-enamel junction mesial
         4B = cemento-enamel junction distal
         4C = cemento-enamel junction buccal
         4D = cemento-enamel junction lingual
         5 = huge caries
