Results: Effective use of portable dental equipment for treatment reduces the rate of baby tooth decay to 23.7% (before intervention, 41.9%), and the intervention effectiveness is 40.3%. The rate of permanent tooth decay after intervention decreased to 28.9% (before intervention, 50.5%), and the effectiveness of intervention was 41.9%. Effectiveness on tooth decay index: after the intervention, the tooth decay index decreased to 0.60 (before the intervention, it was 1.38), and intervention effectiveness was 63.4%. Conclusion: Using portable dental equipment to treat tooth decay at school has contributed to limiting the increase in tooth decay rate among boarding junior high school students of ethnic minorities in Tuyen Quang province.
