Forensic Age Estimation of Chinese Malaysian Adults by Evaluating Occlusal Tooth Wear Using Modified Kim’s Index

Table 2

Modified Kim’s index to score the teeth wear [14].

Score	Premolar	Molar
(0)	No visible wear
(1)	1P/1L	1P/1L/2P/2L
(2)	2P/2L/1S/1B	3P/3L/4P/4L/1S/1B/2S/2B
(3)	2S/2B	3S/3B/4S/4B
(4)	Wear on more than 2/3 of occlusal surfaces
(5)	1Pc/1Lc	1Pc/1Lc/2Pc/2Lc
(6)	2Pc/2Lc/1Sc/1Bc	3Pc/3Lc/4Pc/4Lc/1Sc/1Bc/2Sc/2Bc
(7)	2Sc/2Bc	3Sc/3Bc/4Sc/4Bc
(8)	Concavity on more than 2/3 of occlusal surfaces
(9)	Filling, , (all teeth)
(10)	Missing, stump of tooth, pontic, denture (all teeth)

the extent of the filling materials or caries does not exceed 1/3 of the occlusal surface so that the degree of occlusal wear can be determined, the pertinent score should be given; P, point like wear facet less than ca. 1 mm in diameter; L, linear wear facet less than ca. 1 mm in width; S, surface like wear facet greater than ca. 1 mm in diameter; B, band like wear facet greater than ca. 1 mm in width or wear facet involving more than two surface like wear facets; “c” (concavity), the wear of dentin; in the situation where a tooth has several different degrees of occlusal wear, the highest degree should be selected as the occlusal wear score.
