Cutaneous sinuses of dental origin

We report a case of a cutaneous sinus related to a non-vital lower premolar. The case was misdiagnosed by non-dentally trained medical staff and subsequent treatment proved ineffective. Following referral to an Oral and Maxillofacial clinic the correct cause was established. Correct treatment was followed by rapid resolution of signs and symptoms. This case highlights the need for healthcare professionals dealing with such patients to be aware of the dentition as a cause for cutaneous sinuses in the head and neck region. Those professionals not dentally qualified should enquire about dental pain and consider referral to the dental practitioner or a specialist department for further evaluation. Even those with a dental background can be fooled and a through history and examination is paramount, supplemented by special investigations were appropriate.
