RESUMO

The aim of this study was to assess the behavior and physiological alterations observed in Down Syndrome children during caries removal using the mechanical or the chemo-mechanical (Carisolv TM ) methods and a 2% lidocaine anesthesia without vasoconstrictor. The study was conducted in 20 ASA I children between 5 and 12 years of age, being 10 with Down Syndrome (experimental group) and 10 “normal” children (control group). Behavior alterations were observed using the modified Venham index. The following physiological parameters were measured automatically using a Criticaire System® - Scholar II: heart rate, systolic and diastolic blood pressure and oxygen saturation. The behavior and physiological assessment were performed in 5 stages of caries removal: (1) 5 minutes before local dental anesthesia; (2) during local dental anesthesia; (3) during caries removal; (4) immediately after restoration; and (5) 5 minutes after the end of the treatment. The physiological parameters observed during caries removal were compared to the child’s baseline measurements. The phase of caries removal showed the greatest alteration in the behavior and all physiological aspects, except for oxygen saturation. No significant difference was found in the behavior alterations between the two groups (p >0.05). Statistically significant difference was observed between the groups and the caries removal method in relation to the heart rate (p <0.01). In the control group (normal children), the heart rate decreased during the chemo-mechanical caries removal method and increased when only the mechanical method was used. In the Down Syndrome group (experimental group), the opposite occurred, heart rate increased when the chemo-mechanical method of caries removal was used and decreased with the mechanical method. No statistical significant difference was observed between the two groups of children and the two caries removal methods studied in relation to oxygen saturation and systolic and diastolic blood pressure.
