RESUMEN
Injuries to the teeth and surrounding structures are relatively common. Although traumatic injuries caused by falls or activities related to sports are widely discussed, the same cannot be said regarding accidents arising from non-professional extraction of primary teeth. The present study reports a 6-year-old male child who underwent mandibular alveolar bone fracture during non-professional extraction of his central lower left incisor at home, performed by his 30-year-old aunt. The root of the tooth was with an irregular physiological resorption, which acted as a lever component for the mechanical force applied, leading to bone fracture. Although not common, the possibility that dental roots with irregular resorption can act as a possible risk factor for accidents if the parents or guardians of children during the period of transitional dentition try to perform intentional extraction of primary teeth should be highlighted. Parents should always consult a professional, preferably a pediatric dentist, for monitoring this period of transitional dentition.

Os cimentos obturadores podem ser à base de hidróxido de cálcio, óxido de zinco e eugenol, ionômero de vidro, de natureza resinosa com metacrilato em sua composição ou, ainda, de silicone. Eles deveriam ser submetidos à investigação sobre seu possível efeito genotóxico e mutagênico antes de serem lançados no comércio especializado, com livre comercialização, pois essas propriedades fazem parte do conceito de biocompatibilidade. No presente artigo, destacam-se os tipos de testes e os conceitos de genotoxicidade, mutagenicidade e carcinogênese.
