Traumatic proliferative mucogingival nodular lesions can develop on the mucosa due to repeated occlusal contact with the opposing teeth. In cats, these lesions typically appear on the alveolar or buccal mucosa near the mandibular first molar, caused by the repeated trauma from the upper fourth premolar and/or the first molar. They can also occur in other locations. These lesions share characteristics with the reactive oral pyogenic granuloma found in humans.
Surgical excision of the lesion is usually not enough to prevent recurrence. There are two possible treatments to resolve these lesions: conservative treatment and treatment through the sealing of dentinal tubules.
Conservative treatment focuses on crown reduction and sealing the dentinal tubules.
If the pulp is exposed, a pulp treatment (vital pulp therapy) will need to be performed. Non-conservative treatment involves extracting the tooth that is causing the trauma.
In summary, traumatic proliferative mucogingival nodular lesions can develop on the mucosa due to repeated occlusal contact. Surgical excision and crown reduction can help manage these lesions, but in some cases, extracting the affected teeth may be necessary to prevent recurrence.
