摘要

Purpose/objectives

Molar incisor hypomineralisation (MIH) is a common developmental defect of enamel (DDE) seen in children. In Malaysia, dental therapists (DTs) are well-positioned to support early detection through the school dental service. However, most DTs lack adequate training and confidence in managing MIH. This study aimed to evaluate the outcomes of the virtual molar incisor hypomineralisation–early detection and intervention training module (MIH–EDIT) by comparing the DTs’ knowledge scores (KS) and photographic assessment scores (PS) before (T0), immediately after (T1) and 2 weeks after (T2) training.

Methods

A before-and-after study was conducted among DTs in Sarawak, Malaysia. Participants received a 1-day virtual MIH training and completed a self-administered questionnaire and photographic assessment of MIH at T0, T1 and T2. Data were analysed using descriptive statistics and repeated measures ANOVA.

Results

In total, 187 DTs completed this virtual MIH training. There was a significant increase (p < 0.001) in the mean KS from T0 (31.95 ± 11.68)–T1 (49.76 ± 3.76) and T0–T2 (48.18 ± 4.83), but not from T1–T2 (p = 0.098). There was a significant increase (p < 0.001) in the mean PS from T0 (13.94 ± 4.52)–T1 (21.41 ± 5.04) and T0–T2 (20.14 ± 5.50), while a small but significant decrease (p < 0.001) was observed from T1–T2.

Conclusions

Within study limitations, the MIH–EDIT improved DTs knowledge on MIH and their ability to detect MIH over the short term. This virtual MIH training has the potential for nationwide adoption into DT training and continuing professional development programmes, enhancing MIH early detection and intervention in clinical practice.
