Osseous lesions involving the periodontium, and which are sometimes associated with discomfort and pathologic changes such as swelling or the development of a sinus tract, are not always due to periodontal disease. Thus, it is not uncommon to find a dentition with generally good periodontal health but with one tooth having a severe isolated bony periodontal defect. In other cases, periodontal treatment may result in a general improvement, except in relation to one tooth which does not respond to the therapy. Very often these cases are instances of combined periodontal-endodontic lesions, but which are solely of pulpal origin. This paper serves to help the dental practitioner recognise the disease process underlying the condition and appreciate its effective management with non-surgical root canal treatment.
The design and development of a new fine fiberscope (1.0 mm outer diameter) is described, that includes an irrigation system for endoscopic use. This effectively allows visualisation of fields involved in periodontal disease. This fiberscope has been used in our clinic for seven years to diagnose and treat periapical and periodontal lesions through fistulae and periodontal pockets. The fiberscope has been applied to endodontic surgery for the inspection of root apices and the denuded root surfaces, in addition to the cut root face, rootend cavity and root-end filling after root-end resection. The advantages of endoscopy compared to surgical microscopy are portability and easy adjustment of direct viewing angle to examine around corners without the use of additional mirrors. Furthermore, the fiberscope can be utilised through the sinus tract or a minimal incision without the need for surgical flaps to observe the root surface, periapical tissue and foreign materials before, during and after curettage. The system requires little local anaesthesia, no large incisions, no opening flaps and no sutures. As a result, postoperative symptoms are minimised. Periapical curettage using a fiberscope represents a useful and minimally invasive surgical procedure.
