ABSTRACT
The study is associated with the effect of aspirin (Acetyl Salicylic Acid) on the microhardness of mineralized tissues of the offspring's teeth, in response to the ingestion of the drug during pregnancy. Aspirin is a widely used analgesic and antipyretic medicine, for symptomatic treatment. Misuse of this drug during pregnancy may instigate developmental defects in offspring. An experimental control study was designed, in which female rabbits were taken as representative mammalian models and treated with aspirin during pregnancy. Their offspring's teeth were used to assess the microhardness of dental tissues. The rabbits were alienated into two groups, treated and control, consisting of seven rabbits in each set (n= 7). Microhardness was evaluated in three types of the sample teeth. The total number of teeth examined were, 2x7x12= 168 samples. Vicker's Hardness degree values were measured and recorded vis-à-vis (50 g for 15 s with 3 indentations per specimen on enamel and dentine separately). The range of hardness obtained was statistically analyzed and the Student's t-tests was applied, with the aid of SPSS version 20. The P-values for both enamel and dentine from maxillary incisors and molars were less than 0.05. The same trend was observed in the mandibular teeth. However, a teratogenicity of Acetyl Salicylic Acid was pragmatic in the recent in vivo studies. Based on the analysis, it was evident that the aspirin administration could produce negative effects leading to reduction in the microhardness of dental tissues of the offsprings.
RESUMEN
El estudio asocia el efecto de la aspirina (ácido acetil salicílico) sobre la microdureza de los tejidos mineralizados de los dientes de crías, en respuesta a la ingesta del fármaco durante la preñez. La aspirina es un analgésico y antipirético ampliamente utilizado para el tratamiento sintomático. El mal uso de esta droga durante la preñez puede inducir defectos en el desarrollo de las crías. Se diseñó un estudio experimental de control, en el que se tomaron conejas como modelos de mamíferos representativos y fueron tratados con aspirina durante la preñez. Los dientes de sus crías fueron utilizados para evaluar la microdureza de los tejidos dentales. Los animales fueron distribuidos en dos grupos, tratados y control, con siete animales en cada grupo (n= 7). La microdureza se evaluó en tres tipos de dientes de la muestra. El número total de dientes examinados fueron 168 (2x7x12). Se midieron y registraron valores del grado de dureza Vickers vis-à-vis (50 g por 15 s con 3 indentaciones por especimen sobre el esmalte y la dentina por separado). Se analizó estadísticamente la gama de dureza obtenida y se aplicaron pruebas t de Student con la ayuda del programa SPSS versión 20. Los valores de p para el esmalte y la dentina de los incisivos maxilares y molares fueron menores a 0,05. Se observó la misma tendencia en los dientes mandibulares. Sin embargo, teratogenicidad producto del ácido acetil salicílico se encontró en recientes estudios in vivo. De acuerdo al análisis de los resultados, se evidenció que la administración de aspirina provocó efectos negativos que determinaron la reducción de la microdureza de los tejidos dentales de las crías.
