CRP and dentin dysplasia: Laboratory markers like C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) are typically normal [18,39,57,58,59], but some studies have shown elevated levels of these markers in DD patients, such as a study described in a review by Hansson et al. [19], where it was found that 66% of 112 women with DD had an ESR greater than 15 mm/h, while Herbst et al. [18] reported in their study that 33.4% of DD patients had elevated CRP levels and 37.5% had increased ESR levels.
