4、icine, Minia University, Minia City, Egypt.OBJECTIVES: To assess the level of acceptance and discomfort experienced by secondary school students when undergoing an atraumatic restorative treatment (ART) restoration.SUBJECTS AND METHODS: Ninety secondary school students, aged 14 and 15 years, were in

5、cluded in the study. The ART restorations were prepared in 90 cavities and restored using an encapsulated high-viscosity glass ionomer. The depth of the cavities was judged from radiographs and clinically into outer, middle and inner third of dentine. Using a graded periodontal probe, cavity size wa

6、s measured, into approximately half the width of the mesiodistal and buccolingual/palatal distance of the occlusal surface. The students were asked about the level of sensation experienced during cavity preparation immediately after completion of restoration. chi(2)-Test was used to test the effect

7、of cavity depth and size on sensitivity from the teeth.RESULTS: Of the 90 students, 6 (6.6%) and 26 (29.2%) experienced pain and discomfort, respectively, during cavity preparation, more often in large than in small cavities (p = 0.003) and in cavities extending into the inner third than in the midd

8、le and outer third of dentine (p 0.0001). Only 1 student reported postoperative sensitivity.CONCLUSIONS: The ART approach to treat dental cavities was well accepted by this group of secondary school students. Only a few reported pain during cavity instrumentation, and this was more prevalent in large cavities and in cavities with the floor close to the pulp.Hobdell M, Petersen PE, Clarkson J, Johnson N. G
