hello and welcome to hcm forum Joshua,
according to the dental history presented by you , it states that you have had peripheral giant cell granuloma
for which a surgery was performed by your dentist
, i would like to inform you that surgical excision is the only treatment for it but yes it has a tendency to grow back if even minute remnants are left behind following its surgical excision.
therefore steroidal injections will only prevent it from coming back, but to confirm whether its calcium deposit or granuloma, ct scan
reports will be required.
i cannot rule out the diagnosis until i see the reports,
kindly get the tests done because that is the only means of confirmation.
i wish you good health,
