HAS Carnoy's solution a role in the management of recurrent peripheral giant cell granuloma?

OBJECTIVE

this study aimed to evaluate the efficacy of local application of Carnoy's solution following the surgical excision of recurrent PGCG.

PATIENTS AND

METHODS

40 patients who sought treatment for recurrent PGCG were included in this study. According to the type of treatment the patients were classified randomly into two equal groups. The lesions in all patients were excised down to the alveolar bone followed by aggressive curettage. Then only in group II, Carnoy's solution was applied for 5 min. Clinical follow-up was done for 1 year to evaluate the tissue healing.

RESULTS

patients were 23 females and 17 males, with an average of 35.9years. Recurrent PGCGs occurred most commonly in fifth decade of life (25 %). Maxilla (57.5 %) was involved more than the mandible. The lesions were found posteriorly in 27cases and anteriorly in 13cases. The average size of the lesions was 2.9 cm. Histologically, foci of calcifications occurred in 12cases. Recurrence occurred in 5 cases: 4 in group I and 1 in group II. Bone healing was appropriate in all patients without sequestration.

CONCLUSION

the use of Carnoy's solution following surgical removal of recurrent PGCG decreases their recurrence rates. The technique is safe, and conservative with low tissue morbidity.
