Effect of audiovisual distraction on children's behaviour, anxiety and pain in the dental setting.

AIM: To evaluate whether the parental perception of the patient's anxiety, children's anxiety, pain, behaviour and heart rate of paediatric patients improves when an audiovisual technique is used as a distraction method during dental treatment. MATERIALS AND METHODS: This non-randomised crossover trial was performed with 34 patients aged 6-8 years, who required a minimum of two treatment visits for restorative therapy. During the last visit, the patient was shown a cartoon film. RESULTS: There was a significant improvement in the global behaviour when children were shown a cartoon film (P < 0.001). A significant increase in heart rate was recorded in both visits (P = 0.0001) when the anaesthetic was injected. A 97% of the sample would like to continue seeing their chosen film during subsequent visits. No statistically significant differences were found (P > 0.05) between the visits in terms of parental perception of the patient's anxiety, or the patient's self-reported anxiety, pain and heart rate. CONCLUSIONS: The use of the audiovisual material used as a method of distraction produces a global improvement in patient behaviour, but not in parental perception of the patient's anxiety, self-reported anxiety, pain or heart rate according to the measurement scales used. This material is also highly accepted by paediatric patients.

Objective and subjective measures for assessing anxiety in paediatric dental patients.

AIM: Anxiety has been defined as a nonspecific feeling of apprehension towards a concrete situation that does not necessarily involve a previous experience. Dental anxiety can prevent patients from cooperating fully during dental treatment. Given that there is a connection between dental anxiety and uncooperative behaviour, it is important for dentists to be able to assess anxiety in their patients. There are many methods for such assessment, and in children they depend on age and intellectual development. These measures can be objective or subjective, depending on the method used to quantify the degree of anxiety. The aim of this literature review was to analyse the objective and subjective scales that are used most commonly to assess the degree of anxiety of children in a dental setting. CONCLUSION: Knowing the degree of anxiety of dental children is important in order to guide them through their dental experience. Their level of cooperation will also improve and anxiety will be reduced as well.
