Aim: This study aims to assess postoperative pain after treatment with the Hall technique versus silver diamine fluoride with the management of carious primary molars. Materials and methods: Forty-eight carious primary molars with vital pulp were divided into two equal groups (n = 24). In the intervention group, the teeth were treated with 38% Silver Diamine Fluoride. In the control group, the teeth were treated with the Hall technique. Results: The risk of 1 day postoperative pain is 16% (ARR= 0.16 CI -0.0037 to 0.358) more in the Hall technique compared to the SDF technique; the same result was found at 2 days and 1 week. The risk of 6 months postoperative pain is 25% (ARR= -0.25 CI -0.449 to 0.06) less in the Hall technique compared to the SDF technique. Conclusions: The SDF had a lower risk of postoperative pain by 16% than the Hall technique at 1 day, 2 days, and 1 week. The Hall technique had a lower risk of postoperative pain 25%, than SDF at 6 months.
