Physiologic and behavioural signs during a dental appointment in children and teenagers with Cerebral Palsy: a comparative cross-sectional study.

AIM: To evaluate the heart rate (HR) and behaviour of children and teenagers with Cerebral Palsy (CP) when having a dental appointment. METHODS: A comparative cross-sectional study was carried out with 60 participants with CP, between 2 and 14 years old (study group-SG), and 60 normotypical individuals (CG). The sample was paired according to age, gender and socioeconomic status. Behaviour was evaluated during dental prophylaxis using the Frankl Scale, and HR was measured at five moments: before the appointment, when sitting in the dental chair, during the clinical examination, during prophylaxis and immediately after prophylaxis. Mann-Whitney, Friedman and Chi-square tests were applied at a significance level of 5%. RESULTS: SG presented significantly higher HR (p < 0.001) and more participants with uncooperative behaviour (p < 0.001) than CG in all observational periods. Furthermore, SG participants with uncooperative behaviour presented higher HR values than those in SG who were cooperative in all observational periods (p ≤ 0.002). CONCLUSIONS: Individuals with CP have a higher HR before and during the clinical session, and are frequently more uncooperative with the procedure than normotypical individuals.
