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.

analysis.

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.

Age estimation from pulp/tooth area ratio (PTR) in an Indian sample: A preliminary comparison of

three mandibular teeth used alone and in combination.

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.
