This is analogous to the electronic entry of periodontal probing data in millimeters at 6 points around each tooth to allow calculation of the clinical attachment level for each probed site. Dental caries is a multifactorial disease involving many complex risk and protective factors. Lesion extension and DDR images were scored as follows: D0=sound surface, D1/D2=caries restricted to the outer/inner-half of the enamel, and D3/4=caries restricted to the outer/inner-half of the dentin.

The dopamine D4 receptor appears pharmacologically similar to D2 and D3 receptors but has a 10-times-greater affinity for the atypical antipsychotic clozapine, suggesting that D4 receptors may be the main site of clozapine's antipsychotic action.

The two isomers of D2 are pharmacologically identical except for minor differences in their affinity for specific G-proteins. Current theories on these secondary changes include electrophysiological adaptations, such as a depolarization of dopamine neurons and changes in gene expression of dopaminergic and dopaminoceptive neurons. 1993;16:299-321.13.

It is highly recommended that D1 and D2 radiographic caries lesions undergo TTS in order to increase diagnostic accuracy and decide whether to perform restorative treatment. Atypical neuroleptics have been shown to cause fewer extrapyramidal symptoms, which, in the case of clozapine, may be secondary to decreased blockade of D2 receptors in the striatum compared with classical neuroleptics (See Figure 5).
