A Comparative Rugoscopic Study of the Dentate and Edentulous Individuals in the South Indian Population

Abstract

This study analyzes the rugae pattern in dentulous and edentulous patients and also evaluates the association of rugae pattern between males and females. Aims and Objectives. This study aims to investigate rugae patterns in dentulous and edentulous patients of both sexes in South Indian population and to find whether palatoscopy is a useful tool in human identification. Materials and Methods. Four hundred outpatients from Sree Balaji Dental College and Hospital, Chennai, were included in the study. The study group was equally divided between the sexes, which was further categorized into 100 dentulous and edentulous patients, respectively. Results. The edentulous male showed the highest mean of wavy pattern and total absence of circular pattern while the edentulous female group showed the highest mean of curved pattern and total absence of nonspecific pattern, while dentate population showed similar value as that of the overall population such as straight, wavy, and curved patterns. Conclusion. The present study concludes that there is similar rugae pattern of distribution between male and female dentate population while there is varied pattern between the sexes of edentulous population. However, the most predominant patterns were straight, wavy, and circular patterns.

Effect of tooth loss on rugae pattern in complete and partially edentulous individual: A forensic perspective

“…Among completely edentulous individuals (group A) Sinnous pattern (2.1±1.65) is more common followed by line (1.4 ± 1.39); curve (1.4 ± 1.48) and bifurcated type (0.6 ± 0.81) whereas in partially edentulous individuals (group B) Line pattern (2.6 ± 1.71) is more common followed by sinnous (2.2 ± 1.74); circle (0.6 ± 0.78) and bifurcated type (0.3 ± 0.61) based on number and distribution. This finding was disagreeing with the results of Jawad IA (Wavy, curved) in Iraq population [8] , Kapali et al (Circular and straight) in Australian group [15] and similar to result by Bhat G [16] , Deepak et al [17] , Poojya et al [14] and Rajguru et al [18] among Indian population. This difference in mean value of number of rugae and pattern of arrangement could be attributed to several environmental factors such as age, gender, geographical location; local factors like chewing force exerted, presence of denture as well as genetic predisposition.…”

Palatoscopy (Rugoscopy) assistance in forensic investigations

“…6. Rajguru J P et al in 2014 11 analyzed the rugae markings in dentulous and edentulous dentition and also evaluated the association of rugae markings between genders. To sum up in the present study there is similar distribution of rugae pattern between male and female dentition while there is varied pattern between the sexes of edentulous population.…”

Revisión sistemática de las aplicaciones de la rugoscopía en las ciencias forenses

“…En estos casos, la rugoscopía juega un papel preponderante ya que es casi el único recurso bucal para obtener identidad. Se puede afirmar que es un método de identificación confiable, aunque vale destacar que es el grado de dificultad es mayor, a diferencia de los casos dentados donde las rugas palatinas están mucho más marcadas [60]. f) Referencia de otras estructuras anatómicas Las rugas palatinas pueden servir como indicadores o puntos de referencia para determinar la llave anterior maxilar, la forma del arco y la posición de ciertas piezas dentarias.…”
