Abstract
Patients: Case 1: 16 year-old girl. Her chief complaint is severe pain due to the soy sauce when eating. A lower right canine was displaced up-downward when tapping the tooth and stomatitis with shapes of oval formation on the buccal and lingual gingivae close to the tooth periapical areas were found. Case 2: 42 year-old male. His chief complaint is inlay loosening. An upper left canine displaced in buccal direction when grinding the tooth and a stomatitis formed on the buccal gingiva from the cervical region of the tooth to the upper left second bicuspid. Case 3: 31 year-old female at her regular medical examinations. A lower left canine was displaced up-downward when tapping the tooth and a stomatitis of oval shape was found on the buccal gingiva close to the periapical area of the tooth. Case 4: 41 year-old female at her regular medical examinations. An upper right second bicuspid displaced in the buccal direction when grinding the tooth, and a stomatitis of oval shape was found on the buccal gingiva close to the periapical area of the tooth. Case 5: 33 year-old female under her orthodontic treatment. An upper right first molar displaced in the buccal direction when grinding the tooth, and a stomatitis of oval shape was found on the buccal gingiva close to the periapical area of the tooth.
Similar symptoms of the stomatitis were edema. There were no erosions or aphthous ulcers and the stomatitis was painless by palpation except for case 1, which had the pain of 1/10(VAS) by palpation. All stomatitis disappeared after we performed occlusal adjustment for the teeth.
Discussion: A displacement of tooth under tapping or grinding generates an external force to the periodontal tissue. It is thought that the stomatitis forms in the areas of force existence. On the other hand, the stomatitis disappeared when the displacement of teeth was alleviated by the occlusal adjustment. When we associated displacement of teeth with occlusal forces, occlusal trauma was responsible for these five cases of stomatitis.
