Regarding "Multiple calcifying hyperplastic dental follicle (MCHDF): a case report"

ultiple calcifying hyperplastic dental follicles (MCHDF) are disorders characterized by multiple unerupted teeth with abundant calcifications and rests of odontogenic epithelium in enlarged dental follicles. Recently, I encountered a case of MCHDF and while reviewing the scientific literature, I came across a similar case report published by Jamshidi et al, published in the Journal of Dental Research, Dental Clinics, Dental Prospects. The authors erroneously declared their case report as the 11th case of MCHDF based on their wrong interpretation of the total number of cases reported till then. The two cases reported by Lukinmaa et al were limited in the same quadrant of the jaw, and hence, were declared by Cho et al as single hyperplastic dental follicles (SCHDF) and not MCHDF. Thus, the case report by Jamshidi et al should be suitably considered as the 9th case of MCHDF in the literature and not 11th in number. The detailed summary of all the nine cases, including the case reported by Jamshidi et al is given in the Table below. Editor’s note
