External root resorption in common odontogenic cysts and ameloblastomas of the jaw: A retrospective radiographic study in an Asian population

Abstract

Common odontogenic cysts and ameloblastomas of the jaw are often associated with external root resorption of adjacent teeth. Principal findingsAmeloblastomas were eight times more likely to cause root resorption than odontogenic keratocysts while dentigerous cysts were three times more likely to cause root resorption than odontogenic keratocysts. We found a clear association between the type of lesion and the presence of external root resorption.

Present status and future directions: Root resorption

“…It has been reported that orthodontic forces of 50-100 cN are optimal for orthodontic tooth movement and low risk of surface resorption (Theodorou et al, 2019). Teo et al (2021) determined that the incidence of surface resorption associated with cysts was 38% in an Asian population (Teo et al, 2021). The incidence of surface resorption caused by ameloblastomas and dentigerous cysts appears to be higher than with odontokeratocysts (OKC; Struthers & Shear, 1976;Teo et al, 2021).…”

Ameloblastomas and dentigerous cysts are eight times and three times more likely to be associated with ESR in adjacent teeth compared with OKC, respectively.…”

“…This may be due to increased expression of certain cytokines, e.g. RANK, RANKL and OPG that were involved in mediating odontoclastic activity (Da Silva et al, 2008 ; Teo et al, 2021 ).…”
