Abstract
The validity of the age assessment method based on the "Radiographic Atlas of Skeletal
Development of the Hand and Wrist" by Greulich and Pyle (1st edition 1950) has been frequently
questioned. The purpose of this study was to examine the reliability of this widely used method and
to compare it to various dental and other skeletal age assessment methods. Forty-seven Finnish
children of known ages below 16 years, who perished in Thailand in the Southeast Asian Tsunami on
26 December 2004 were examined. Every victim repatriated to Finland underwent a complete
forensic autopsy including CT-scan, toxicological screening, and diatom analysis in order to establish
the cause of death, as well as DNA testing and dental examination for the verification of the
identification established in Thailand. Age assessment was performed by dental and skeletal
methods. The average difference between the age assessment values obtained by the Greulich and
Pyle method, and the chronological age was 9.7 months. In addition to the Greulich and Pyle
method, an alternate skeletal method, Tanner and Whitehouse 2, resulted in an average age
difference of 10.3 months. Dental age assessment methods were based either on the eruption
(Nyström method, 8 cases, average age difference 5.6 months), or the development of the crown
and roots (Demirjian method, 33 cases, average age difference 5.2 months and ABFO method, 7
cases, average differences 12.6 months). Dental methods proved to be most accurate in childhood
until the teeth-with the exception of wisdom teeth-have erupted and root development is
completed. In adolescence, however, the validity of skeletal methods improves considerably.

Abstract
Uniqueness of the human dentition is a fundamental premise in bitemark analysis. Despite the
importance of this key aspect of bitemark methodology, systematic studies of large populations have
been limited. Furthermore, there have been no investigations of the significance of the third
dimension with regard to dental uniqueness. One hundred digitally scanned mandibular models
were analyzed in both 2D and three dimension (3D) using Landmark software. Additionally, 500 3D
maxillary and mandibular sets were investigated for determining dental match rate. Statistical
analysis was performed with geometric morphometric methods. Results show that measurements in
3D preserve more information about the dentition, reducing but not eliminating random matches in
a sample population of 100 mandibular dentitions. Examination of pairs of maxillary and mandibular
dentitions showed a substantial number of random matches (197 maxillary, 51 mandibular, one of
both maxillary and mandibular). Conclusions indicate that a zero match rate cannot be claimed for
the population studied.

Abstract
Pulp/tooth area ratio (PTR) method of adult dental age estimation has been examined on few tooth
types. We assessed the lateral incisor (LI) and first premolar (PM1) in addition to canine (C) - alone
and in combination. Periapical radiographs from 61 Indians aged 21-71 years were examined. PTR of
LI produced the best age correlation (r = -0.395) followed closely by PM1 (r = -0.362). The canine
revealed the lowest correlation (r = -0.206); among tooth combinations, the three teeth taken
together had the best R value (-0.438) followed by LI + PM1 (-0.435), LI + C (-0.406) and C + PM1 (-
0.37). The standard errors of estimates (S.E.E.) of the regression analyses for the individual teeth and
tooth combinations ranged from ±12.13 to 13.08 years, indicating minimal difference in age
estimates using solitary or multiple teeth. Errors were higher than in European groups (±2.5-5 years)
which may partly owe to moderate age correlation of secondary dentine deposition in Indians.
Moreover, facial soft-tissue superimposition in living subjects evaluated herein possibly precluded
optimal tooth and pulp canal visualization. These indicate that the PTR method should be used
judiciously in age estimation of living Indian adults, although further studies on larger samples with
evenly distributed age-groups is necessary for deriving definitive conclusions.

Determination of palatal rugae patterns among two ethnic populations of India by logistic
regression analysis.

Abstract
Palatal rugae patterns are relatively unique to an individual and are well protected by the lips, buccal
pad of fat and teeth. They are considered to be stable throughout life following completion of
growth, although there is considerable debate on the matter, they can be used successfully in post
mortem identification provided an antemortem record exists. Thus the aim of this study was to
examine palatal rugae shape among two Indian populations and determine the accuracy in defining
the Indian population using logistic regression analysis. The study comprises two groups from
geographically different regions of India with basic origin from Maharashtra and Karnataka state.
The sample includes 100 plaster cast equally distributed between two populations and genders with
age ranging between 18 and 40 years. Impression of maxillary arch was obtained using alginate
impression material and plaster cast was made. The rugae was delineated on the cast using a sharp
graphite pencil under adequate light and magnification and recorded according to classification
given by Kapali et al. and Thomas and Kotze (1983). Chi-Square analysis showed significant
difference in wavy, circular and divergent pattern between the two populations. The straight and
wavy forms were significant in logistic regression analysis. A predictive value of 71% was obtained in
determining the original cases correctly when straight, wavy, curved and circular patterns were
assessed. 70% of predictive value was achieved when all rugae patterns were assessed. Mean
number of rugae was greater in females compared to males with straight pattern showing
statistically significant difference between males and females. Significant difference was recorded
among straight, wavy, circular and divergent pattern between two populations. Consequently this
study demonstrates moderate accuracy of palatal rugae pattern using logistic regression analysis in
identification of Indians.

Abstract
Dental maturation and chronological age estimation were determined from 144 healthy Western
Australian individuals aged 3.6-14.5 years. The results were compared with Farah et al.'s previous
study which comprised a larger heterogeneous sample of Western Australian individuals (n = 1450).
Orthopantomograms were analyzed with the application of Demirjian and Goldstein's 4-tooth
method based on eight stages of dental mineralization. Analysis of variance revealed no significant
differences in dental maturity scores in each age group among the males in both studies; similar
results were seen in the females. Paired t-tests showed no statistical significance overall between
chronological and estimated ages for the males in our sample (p = 0.181), whereas the females
showed significant differences (p <0.001). Our results show that smaller samples may be used when
assessing dental maturity curves for forensic age estimation.

Abstract
The aim of this study was to determine the comparative accuracy of Demirjian's four dental
development methods for forensic age estimation in the Western Australian population. A sample
comprising 143 individuals aged 4.6 to 14.5 years were assessed using Demirjian's four methods for
dental development (original 7-tooth: M(2), M(1), PM(2), PM(1), C, I(2), and I(1); revised 7-tooth:
M(2), M(1), PM(2), PM(1), C, I(2), and I(1); 4-tooth: M(2), M(1), PM(2), and PM(1); and an alternate
4-tooth: M(2), PM(2), PM(1), and I(1)). When comparing all four methods, the 4-tooth method
overestimated age in both males and females by 0.04 and 0.25 years, respectively. The original 7-
tooth was least accurate for males, while the original 7-tooth, the revised 7-tooth, and the alternate
4-tooth were unsuitable for females. Therefore, we recommend the 4-tooth method to be used for
forensic age estimation in Western Australian males and females, as it has the lowest overall mean
deviation and the highest accuracy.

Abstract
Developing teeth are commonly the criteria used for age estimation in children and young adults.
The method developed by Cameriere et al. (Int J Legal Med 2006;120:49-52) is based on measures of
teeth with open apex, and application of a formula, to estimate chronological age of children. The
present study evaluated a sample of panoramic radiographs from Brazilian children from 5 to 15
years of age, to evaluate the accuracy of the method proposed by Cameriere et al. The results has
proven the system reliable for age estimation, with a median residual error of -0.014 years between
chronological and estimated ages (p = 0.603). There was a slight tendency to overestimate the ages
of 5-10 years and underestimate the ages of 11-15 years.
