Para conocer la respuesta al psicofármaco neuroléptico clorpromazina para el control de la conducta en niños que acuden a una clínica dental, se utiliza una muestra de 56 niños (40 cooperadores y 16 no cooperadores con conductas impulsivas "histéricas") y se aplica un cuestionario de 12 variables. El grupo histérico se premedica con clorpromazina (25 mg dos horas antes del tratamiento denta]). Las diez conductas que discriminan al grupo histérico frente al cooperador son: "no abre la boca", "se tapa la boca con la mano", "aparta la cabeza cuando se va a intervenir", "grita", "realiza movimientos bruscos de apartar la mano del profesional", "patalea", "se sienta en el sillón con problemas", "llora", "le asustan los instrumentos" y «tiene las piernas levantadas o los músculos contraídos". Otras dos conductas ("está en tensión" y "no habla ni establece comunicación con el dentista") no discriminan ambos grupos. Al comparar los resultados en el grupo histérico en la primera visita versus la segunda, ya premedicados, en todos los casos se pudo realizar el tratamiento dental, siendo la respuesta a la anestesia, dique de goma, apertura cavitaria "regular" y muy buena la conducta durante la obturación.
In order to investigate the response to the neuroleptic drug chlorpromazine in the behaviour control of children undergoing treatment at a dental clinic, a sample of 56 children was used (made up of 40 cooperators and a further 16 which did not cooperate and presented "hysterical" impulsive behaviours) and a 12 variable questionnaire applied. The hysterical group is pre-medicated with chlorpromazine (25 mg two hours before dental treatment). The ten behaviours that differentiate the hysterical group from the co-operative group are: "refusing to open mouth», "taking hand to mouth", "turning head away when about to he intervened", ",screaming", "making violent gestures to move the dentist's hand away", "kicking», «sitting on the dentist's chair with problems", "crying", "frightened by instruments", "having legs up or muscles contracted". Two other behaviours: "being tense" and "not speaking nor establishing communication with dentist" failed to differentiate both groups. When comparing results for the hysterical group in the first visit versus the second (here with prior medication), the authors found that dental treatment could be carried out. The behavioural response to anaesthesia, application of rubber dam and aperture of cavity was "average" whilst the response to obturation was «very good".
