Peripheral odontogenic fibroma (fibromatous-ossifying epulis) in the area of the vestibular gingiva of LmaxP4 (208) (confirmed through histopathology). A From right to left: LmaxM1 (209) and LmaxP4 (208). B Peripheral odontogenic fibroma (ossifying epulis) in the area of the
vestibular gingiva of LmaxP4 (208). Key diagnostic/treatment points The peripheral odontogenic fibroma (fibromatous-ossifying epulis), on this occasion, in spite of its uncommon location, shows characteristic macroscopic signs of the process. However, a histopathological diagnosis is essential to confirm the process, as well as the orientation of the dental radiological assessment.

Peripheral odontogenic fibroma (fibromatous-ossifying epulis) in the interdental area (mesial) and palatal area of RmaxI1 (101) and LmaxI1 (201) (confirmed through histopathology). A From right to left: LmaxI2 (202), LmaxI1 (201), RmaxI1 (101) and RmaxI2 (102). B Peripheral odontogenic fibroma (fibromatous-ossifying epulis) in the interdental
and palatal areas of RmaxI1 (101) and LmaxI1 (201). C Distovestibular deviation of RmaxI1 (101) and LmaxI1 (201), due to compression
from the tumour. D Dental abrasion in different teeth, with exposure of tertiary dentin. E Image of the peripheral odontogenic fibroma (fibromatous epulis), rostral view. F Dental X-ray: X-ray signs compatible with absence of invasion in the bone tissue
of the neoplasm in the interdental and palatal regions of RmaxI1 (101) and LmaxI1 (201).
F
G Dental X-ray: X-ray signs compatible with vertical bone loss in the interdental
region of RmaxI1 (101) and LmaxI1 (201); possible causes include dental compression and displacement, and periodontal disease.
Key diagnostic/treatment points The peripheral odontogenic fibroma (fibromatous-ossifying epulis) has no infiltration capacity in local bone tissue although in some cases we have observed, if it is located between teeth and increases in size, it can cause displacement (deviation) of regional teeth. 88
