Características individualizantes de rugas palatinas, en laboratorios dentales de Guayaquil Semestre B-2020.

Abstract

Introduction: Rugoscopy or also called rugo-stereography, is the expert process that studies the characteristics, shape, size, position and direction of the roughness of the palate, in living and dead individuals; used as a method of identification Odontological-Criminalistic based on studies, records and classifications of the roughness. Objective: To analyze the individualizing characteristics of palatal wrinkles in dental laboratories in Guayaquil, Semester B-2020. Material and Methods: Exploratory, transversal, qualitative-quantitative, laboratory study. A sample of 80 models that met the inclusion and exclusion criteria was obtained. The shape of the palate, shape, length, direction and position of the palatal wrinkles were recorded by means of recording sheets. Results: From the sample of 80 study models we obtained 888 palatal rugae. Arch shape was analyzed: Oval 93.75%, Triangular 6.25% and Square 0.00%. Shape pattern of palatal wrinkles: Straight A 29.05%, Curve B 23.54%, Sinuous E 18.24% and Point F 12.73%. Size of palatal rugae in relation to arch form: Oval with Principal length > to 5mm 65.99%, Oval with Accessory length 3-4mm 16.33% and Oval with Fragmentary length < 3mm 11.15%. Direction of palatal creases: Divergent 65% and Unified 35%. Position of palatal wrinkles in relation to arch form: Oval Type I 36.25%, Oval Type IV 35%, Oval Type II 20%. Conclusions: The evaluation and analysis of palatal rugae is a reliable and trustworthy means for human identification and individualization.
