“…Hemisection is a viable alternative to extraction in those situations where a portion of a multi-rooted tooth has normal root canal structure and can still perform in health and function after the diseased portion has been removed (Swan et al 1991). As described earlier, the procedure involves removing the compromised tooth structure (root and part of the crown).…”

“…After appropriate preparation, a root filling is then placed in the residual root and the crown sealed. The process of root canal treatment removes the dental nerves, preserves a functional tooth segment and thus maintains chewing physiology (Swan et al 1991). Even if a treated tooth goes on to develop further resorption, the lack of nerves prevents recurrence of tooth pain permitting retention of the tooth until it becomes structurally unsound.…”

Mandibular molar tooth function is important for cats, however, current veterinary dental practice is to extract teeth affected by even very small resorptive lesions. The aim of this article was to describe an attempt at salvaging mandibular molar teeth where the mesial root and associated crown remained unaffected by resorption. Three cats presented with localised resorption of the distal root of a mandibular molar tooth were treated by hemisection, extraction of the distal root and endodontic treatment of the mesial root. The oral function was maintained in all three cats with no clinical evidence of pain or further resorption at follow-up 10 months post treatment. One cat was also examined at 27 months post treatment, at which stage there was still no oral discomfort and the tooth appeared fine but there were radiographic signs suggestive of early apical resorption. Whilst longer term follow-up is required, it appears that hemisection may be an acceptable treatment for these localised resorptive lesions, at least for the short to medium term.

The furcation is the anatomic area where the roots divide on a multirooted tooth. Periodontal disease causing alveolar bone loss can lead to furcation lesions of various stages. Once furcation involvement has occurred, the area can be more difficult to clean or treat due to the complex anatomy and morphology of furcations. Teeth with short root trunks, longer tooth roots, and roots with wide furcation entrance areas/degrees of separation and wide root divergence are considered better candidates for long term maintenance. Dog teeth possess many of these advantageous anatomic features compared to human teeth. Treatment options for teeth with furcation lesions include: closed debridement, open debridement, furcation plasty, tunneling, partial tooth or root resection, root separation (hemisection or trisection), regenerative therapies, or exodontia. There are many factors to consider in determining treatment options. The favorable and unfavorable characteristics for maintenance of teeth with furcation lesions are summarized. Home care and ongoing professional care are important aspects of periodontal disease control for any patient. Studies of systemic and local antibiotic therapies in human patients have not demonstrated reduction of furcation stages, and probiotic effects at furcation sites have not been specifically examined. Human review studies show that most molar teeth once deemed “hopeless” due to stage 3 furcation lesions can be maintained for at least 5 to 15 years with supportive periodontal therapy. Similar long term studies in dogs are needed to improve the evidence-based management of canine patients with furcation lesions.
