Serotonin's effects on dopamine can be mediated by 5-HT2, 5-HT1A and 5-HT3-receptor systems. Forcing an explorer into any site to detect a lesion maycause cavitation and eliminate the chance to remineralize the previously intact surface. Established and active lesions may be white or brown and enamel has lost its gloss. Its efficacy in this population may, in part, be due to its increased affinity for D4 or other limbic dopaminergic receptors and/or its serotonin-5-HT2 antagonist properties. 2019 Nov;22(11):1576-1582. doi: 10.4103/njcp.njcp_237_19.
