Abstract

The present invention is related to a method for obtaining dental pulp and root cement in the forensic dentistry field, wherein the method comprises the steps of: (a) obtaining a tooth; (b) taking a digital radiography to the tooth; (c) external rehydrating of the tooth; (d) perforating the rehydrated tooth; (e) internal rehydrating of dentin pulp complex (f) obtaining rehydrated root cement; (g) obtaining rehydrated dental pulp content with a low speed rotation tool; and (h) storing, preservation, processing and/or analyses of the rehydrated dental pulp content and rehydrated root cement, and the use of this method and kits thereof for forensic identification, estimation of post mortem interval (early and late) and determination of possible causes of death.

Dependent claims

A method for forensic identification and/or estimation of post mortem interval of a subject in need thereof, wherein the method comprises the steps of:

(a) obtaining a tooth;
(b) taking a digital radiography of the tooth to determine the exact location of one or more access sites for (d) step perforation;
(c) external rehydrating of the tooth;
(d) perforating the rehydrated tooth;
(e) internal rehydrating of dentin pulp complex (f) obtaining rehydrated root cement;
(g) obtaining rehydrated dental pulp content;
and (h) storing, preserving, processing and/or analyzing the rehydrated dental pulp content or rehydrated root cement for forensic identification and/or estimation of post mortem interval of a subject;
wherein said method further comprises cleaning and sterilizing the tooth of (b) step and performing step (c) by immersing the tooth of step (b) in an external rehydration solution (ERS) for 24 to 120 hours at 37° C.
