Genetic study in patients operated dentally and anesthetized with articaine-epinephrine

Abstract

[EN] In this study we wanted to figure out if there was a correlation between OPRM1 N40D, TRPV1 I316M, TRPV1 I585V, NOS3 -786T>C and IL6 -174C>G polymorphisms and the response to locally applied articaine-epinephrine anesthetic. Methods: In this observational study, 114 oral cell samples of patients anesthetized with articaine-epinephrine (54 from men 60 from women), were collected from dental centers in Madrid (Spain). High molecular weight DNA was obtained from oral mucosa cells. The analysis of OPRM1 N40D (rs1799971), TRPV1 I316M (rs222747), TRPV1 I585V (rs8065080) and IL6 -174C>G polymorphism was performed through real-time PCR allelic discrimination using TaqMan probes. Polymorphism NOS3 -786T> C (rs2070744) was analyzed using RFLP-PCR. The studied polymorphisms are involved neither in the response to the anesthetic, nor in the intensity of perceived dental pain.
