Abstract

BACKGROUND

Palato-radicular groove (PRG) is defined as an anomalous formation of teeth. The etiology of PRG remains unclear. The prognosis of a tooth with a PRG is unfavorable. The treatment of combined periodontal-endodontic lesions requires multidisciplinary management to control the progression of bone defects. Some researchers reported cases that had short-term observations. The management of teeth with PRGs is of great clinical significance. However, to date, no case reports have been documented on the use of bone regeneration and prosthodontic treatment for PRGs.

CASE SUMMARY

This case reported the management of a 40-year-old male patient with the chief complaint of slight mobility and abscess in the upper right anterior tooth for 15 d and was diagnosed with type II PRG of tooth 12 with combined endodontic-periodontal lesions. The accumulation of plaque and calculus caused primary periodontitis and a secondary endodontic infection. A multidisciplinary management approach was designed that included root canal therapy, groove sealing, a periodontal regenerative procedure, and prosthodontic treatment. During a 2-year follow-up period, a good prognosis was observed.

CONCLUSION

This report indicates that bone regeneration and prosthodontic treatment may contribute to the long-term favorable prognosis of teeth with PRGs.

Core Tip: The prognosis of a tooth with a palato-radicular groove (PRG) is unfavorable. The treatment of combined periodontal-endodontic lesions requires multidisciplinary management to control the progression of bone defects. Some researchers reported cases that had short-term observations. However, to date, no case reports have described the use of both bone regeneration treatment and prosthodontic treatment for PRG. Herein, we report a patient with PRG who was treated with bone regeneration and prosthodontic treatments, and 2 years of follow-up showed a good prognosis. This report indicates that bone regeneration and prosthodontic treatment may contribute to the long-term favorable prognosis of teeth with PRGs.
