MTA or CEM useful pulp capping option for diode laser pulpotomy in primary molars suggests a new study published in the Journal of Evidence-Based Dental Practice.
Pulpotomy is the most commonly performed treatment for asymptomatic primary molars with exposed dental pulp. This study aimed to assess the clinical /radiographic success of diode laser pulpotomy with mineral trioxide aggregate (MTA), calcium hydroxide (CH), and calcium enriched mixture (CEM) cement as pulp capping agents.

Materials and Methods
This split-mouth randomized clinical trial was conducted initially on 34 children aged 3-8 years but 4 patients left the study before the first follow-up visit and the study was accomplished and analyzed with 30 cases. The patients had at least 3 first/second molars with deep caries that in radiographic evaluation reveled that requiring pulpotomy. Following pulpotomy, the pulp stump was irradiated with diode laser (non-contact mode, 632 nm, 30 mW power) as photobiomodulation mode. Pulp tissue was then capped with MTA, CH, or CEM cement (n=30 in each group). Reinforced zinc oxide eugenol was applied over the capping agent, and the teeth were restored with stainless steel crowns. Teeth were clinically/radiographically assessed at 6, 12, 18, and 36 months, after treatment. Data were analyzed by Cochran and McNemar tests.
Results
All 30 patients showed up for clinical/radiographic follow-ups for up to 36 months. Regarding clinical outcomes, the 6-, 12-, 18-, and 36-month success rates of all experimental groups were nearly similar with no significant difference (p>0.05). Regarding radiographic outcomes, the 6-month success rates were similar among the groups (p>0.05); however, the 12-, 18-, and 36-month outcomes of CEM and MTA groups were similar but significantly superior to that of CH group (p<0.05).
Diode laser irradiation and subsequent capping of pulp tissue with MTA or CEM cement can be employed for pulpotomy of primary molars.
