Sex Chromatin in Dental Pulp: Performance of Diagnosis Test and Gold Standard Generation International Journal of Morphology
Suazo Galdames,Iván; Roa Henríquez,Ignacio; Cantín L,Mario.
The sex chromatin or Barr body is a condensation of chromatin present at the nucleus of cells in female individuals. Their observation is possible in different cell types and is used for the rapid diagnosis of biological sex. The observation of this condensation in cells of the pulp tissue can be useful in the forensic diagnosis of sex, primarily because of the protection it give dental hard tissues, but its diagnostic value has not been tested. The purpose of this study is to analyze the diagnostic value of the observation of sex chromatin in cells of the pulp tissue. We used 40 premolars and third molars20 from men with a mean age of 20.6 years (SD 8.8) and 20 from women with a mean age of 20.4 years (SD 7.4). The pulp was obtained from teeth extracted...

Sex Determination by Observation of Barr Body in Teeth Subjected to High Temperatures International Journal of Morphology
Suazo Galdames,Iván; Flores,Alex; Roa,Ignacio; Cantín,Mario; Zavando,Daniela.
Sex determination is one of the keys in the identification process. A useful histological method for sex determination is the observation of Barr chromatin or Barr body. This study determines the effect of high temperatures on the diagnostic performance of the Barr chromatin observation on teeth. Were used 50 healthy teeth from 25 male and 25 female individuals aged between 14 and 44 years. The teeth were divided into 5 groups (each group with 5 female and 5 male teeth) and were exposed to controlled temperatures of 200, 400, 600, 800, and 1000 degrees C for 5 minutes. The coronal pulp was obtained and the tissue was processed and stained with hematoxylin-eosin. Four histological slides of male and 4 of female individuals were randomly selected, for each...
