Silva – Rethinking Formocresol Pulpotomy in Primary Molars… What Else is Out There? An Update in Pulp Therapy-Silva Rethinking Pulpotomy in Primary Molars What Else is Out There An Update in Pulp Therapy

Video Summary

The speaker, a UCLA pediatric dentistry faculty member, reviews how modern caries science supports less invasive management of deep caries and pulp therapy in children. She explains that caries reflects an imbalance in the oral biofilm and mineral loss, and that sealing bacteria under a well-sealed restoration can reduce viable microorganisms. “Seal is the deal” is emphasized repeatedly: long-term success depends on a leakage-free restoration.<br /><br />She focuses on diagnosing pulp status using careful history, clinical signs (swelling, fistula, palpation, mobility, percussion), and radiographs—especially evaluating the lamina dura, periodontal ligament width, furcation areas, and anatomy such as high pulp horns in primary molars. She contrasts open versus closed lesions: open lesions may remineralize due to mineral exchange, while closed lesions can have direct pathways to the pulp and behave more aggressively.<br /><br />For asymptomatic deep lesions with vital pulps, she advocates selective caries removal and indirect pulp treatment (IPT), leaving firm/discolored dentin to avoid exposure, then placing a liner and restoring. Stepwise excavation (two visits) is mainly for permanent teeth and can reduce pulp exposures and support apexogenesis.<br /><br />She cautions against direct pulp capping for carious primary teeth due to low success. For pulpotomy, accurate diagnosis and spontaneous hemostasis are critical; persistent bleeding suggests pulpectomy or extraction. Current evidence supports MTA (and historically formocresol) over calcium hydroxide for pulpotomy. For pulpectomy, she reviews indications, technique, and favors resorbable Vitapex, warning against over-instrumentation and nonresorbable overfills.<br /><br />She also raises concerns about silver diamine fluoride on deep lesions due to limited pulp-toxicity evidence and lack of radiographs in typical use.
