Mordida posterior a anestesia odontológica / Lip biting following dental local anesthesia

Niña de 6 años de edad, acude a la consulta odontológica24 horas después de una atención previa, mostrando una lesión en el labio inferior, blanco-amarillenta, con áreas de ulceración cubiertas por fibrina (A). La paciente relata prurito y sensación urente con hiperestesia en el área. No hay compromiso del estado general. Descartada una reacción alérgica y angioedema, el diagnóstico fue una úlcera traumática, como resultado de una mordida posterior a la anestesia del nervio alveolar inferior. El tratamiento consistió en ibuprofeno (suspensión oral, 200 mg / 5 ml, en dosis de 10mg / kg cada 8 horas por 5 días) y control clínico cada dos días (primer control, B). La resolución definitiva ocurrió 10días después de la primera atención. Con el fin de prevenir lesiones de los tejidos blandos, el odontólogo debe indicara los padres y cuidadores la importancia del monitoreo del niño por varias horas, luego de la atención odontológica que implique procedimientos con anestesia local por bloqueo troncular (nervio alveolar inferior), recordando que es más seguro para el paciente comer luego de que el efecto del anestésico desaparece (1).

Two faces of nocturnal tongue biting.

Tongue biting associated with tonic/clonic movements of the limbs is common in epileptic patients, however nocturnal tongue biting as the only manifestation of epilepsy is rare. It can be found in frontal lobe epilepsy. Two cases with the same manifestation of nocturnal tongue biting were presented. One was the result of parasomnias-rhythmic movement disorders (RMD) and the other was a result of nocturnal frontal lobe epilepsy. The definite diagnosis of these abnormal nocturnal events was documented by prolonged EEG monitoring and polysomnography with simultaneous video studies. To our knowledge, RMD presenting with nocturnal tongue biting has never been reported in Thailand. Even in the foreign journals it has rarely been reported. It is crucial to make a definite diagnosis of RMD and nocturnal epilepsy to avoid overtreatment in the former and undertreatment in the latter. Symptomatology, diagnostic approach with therapy of these disorders were reviewed.
