Removal of fibrous epulis with Er,Cr:YSGG
laser: case report
G. OLIVI, M. COSTACURTA, P. MATURO, R. DOCIMO ABSTRACT. Background Epulis is a benign tumour located in the area of the alveolar bone, periodontal ligament
and marginal gingiva. A clinical case of Epulis, treated using an Er,Cr:YSGG laser in our Paediatric Dentistry
division of the PTV Hospital, University of Rome “Tor Vergata”, is described. Case report A pink, sessile,
broad-based lesion, elastic in consistency, was detected on the maxillary vestibular gum above the lateral right
incisor. The lesion was removed with Er,Cr:YSGG laser (2780 nm) without anaesthetic infiltration, power ranged
from 1,5 to 2,0 Watts at 20 Hz repetition rate under 20%-15% air-water spray. The histopathological
examination confirmed the diagnosis of fibrous epulis. The immediate postoperative course was excellent, with
no pain or need for anti-inflammatory or analgesic drugs. Wound healing was good after 1 week, and was
completed after 1 month. The patient was followed up for 3-6 months, and checked again after 1 and 2 years to
assess possible relapse. The Er,Cr:YSGG laser has several treatment advantages, fundamental in Paediatric
Dentistry: it requires only topical anaesthesia, it has a high clinical safety, there is a short treatment time, no
surgical sutures are required; no complications were encountered during or immediately following laser surgery,
all resulting in excellent patient cooperation.

The Er-Cr laser has a close affinity with The aetiology of epulis is multifactorial: irritative hydroxyapatite and water, so it can be used both onhard (tooth, bone) and soft tissues (mucosa, gum, pulptissue) [Iaria et al., 2005].

The intraoral clinical examination revealed a vestibular gingival neoformation above the maxillary right lateral incisor that extended from the central incisor to the deciduous canine; it was pinkish, sessile, wide-based, fixed but elastic in consistency, covered by apparently healthy mucous tissue (Fig. 1, The lateral incisor responded positively to pulp vitality tests. Orthopantomography and periapical X-rays were within normal ranges (Fig. 2).

Post-surgical instructions tothe parents and patient included proper home care anda chlorhexidine gel (0,2%) to apply to the wound(twice a day for one week) was prescribed.
The biopsy identified the lesion as removed by a laser, it was 1x0,8x0,4 cm in size, and stored in 10%formalin solution: the histological report confirmed areactive papillary hyperplasia mainly at the fibrousstage, compatible with a diagnosis of fibrous epulis(Fig. 8).
Postoperative follow-up appointments after 1 week and 1 month aimed at evaluating healing and woundrecovery. The patient was seen for further evaluation at3-6 months and 1-2 year to assess possible relapse. A week after the operation the surgical area had not healed completely (Fig. 9).

Laser surgical technique used in this case presented The laser technique used in this study was an effective choice. The therapeutic success was due to less local anaesthetic required: in this case only the positive psychological approach and to the good intraoperative cooperation of the patient; the no analgesic or post surgical anti-inflammatory asymptomatic postoperative follow up without complications led to a better acceptance of this laser the laser’s bactericidal action and lack of collateral surgical treatment by the young patient and parents.
