The purpose of the study was to assess and compare the masticatory performance in children receiving preformed metal crown by Hall technique and conventional technique.
Children having teeth indicated for restorative/endodontic therapy and belonging to the age group of six to ten years were invited to participate in the study. Eighteen children received preformed metal crowns (PMCs) by Hall technique. Meanwhile, nineteen children received preformed metal crowns by the conventional technique. Their masticatory performance (MP) was assessed at T0 (pre-intervention), T1 (day 1 post-intervention), T2 (1 week), T3 (2 weeks), T4 (1 month) and T5 (3 months) using Hue-check Gum® (University of Bern, Switzerland). The chewing gum samples were scanned within 24 h of their collection and processed in the ViewGum Software©. The software calculated the hue value (VOH) which indicated the masticatory performance of the individual. A questionnaire was given to the parents at T4 and T5 to assess any discomfort or pain associated with PMCs placed in both groups.
The evaluation of masticatory performance using the two-color chewing method revealed reduction in MP on day 1 post-intervention (p < 0.001) for both groups. However, the MP values recorded at T5 were comparable to the baseline values at T0 (p = 0.009). No significant discomfort or pain was reported in both groups.
The findings of the current clinical study indicate that placement of PMCs by both conventional and Hall technique in children deteriorates their MP which equilibrates within 1 month.

本研究旨在评估和比较 Hall 技术和传统技术预成金属冠修复儿童的咀嚼效能。
邀请六至十岁需行修复/牙髓治疗的儿童参与本研究。18 名儿童采用 Hall 技术行预成金属冠修复,19 名儿童采用传统技术行预成金属冠修复。采用 Hue-check Gum®(瑞士伯尔尼大学)于 T0(干预前)、T1(干预后第 1 天)、T2(1 周)、T3(2 周)、T4(1 个月)和 T5(3 个月)评估其咀嚼效能(MP)。收集咀嚼胶样本后 24 小时内扫描,并在 ViewGum Software©中处理。该软件计算出表示个体咀嚼效能的色调值(VOH)。于 T4 和 T5 时向家长发放问卷,评估两组中放置预成金属冠相关的任何不适或疼痛。
采用双色咀嚼法评估咀嚼效能显示,两组儿童干预后第 1 天 MP 均降低(p<0.001)。然而,T5 时的 MP 值与 T0 时的基线值相当(p=0.009)。两组均未报告明显不适或疼痛。
本临床研究结果表明,传统技术和 Hall 技术行预成金属冠修复均会降低儿童的 MP,1 个月内可恢复平衡。
