Cracked tooth and endodontic-periodontal lesion: 2-years follow up of a conservative treatment

This study report diagnosis and management of an endodontic-periodontal lesion in a cracked mandibular tooth after a cyclist’s fall. A 34-year-old female patient with a chief complaint of pain and edema in the region of the mandibular right first molar was evaluated and treated. Patient presented excellent oral health. After clinical, radiographical and tomographic exams, it was diagnosed an acute periapical abscess in stage II combined with tooth cracks and a periodontal involvement (endodontic-periodontal lesion). After emergency dental care it was performed subgingival scaling and root planing, definitive endodontic treatment, indirect definitive restoration (overlay) combined with a reinforcement of the tooth structure with a high-resistance polyethylene tape. Patient was periodically followed up until 24 months and treatment was successful. It can be concluded that a correct diagnosis and a conservative and well-planned and -executed treatment of a compromised tooth by cracks can have good results even endodontic-periodontal lesion is present.
