Recurrent ulcers occuring on gingival and palate are most probably
1) Aphthous ulcers
2) Herpes simplex
3) Koplick spots
4) Lesions of Behcet"s syndrome
Oral Pathology
Answer: 2
Recurrent ulcers on the gingiva and palate are most commonly associated with herpes simplex virus (HSV) infections. Herpes simplex can cause painful vesicular lesions that eventually ulcerate, leading to recurrent oral ulcers, particularly in the mucosal areas such as the gingiva and palate.
Aphthous ulcers (option 1) typically occur on non-keratinized mucosa and are not usually found on the gingiva. Koplick spots (option 3) are associated with measles and are not ulcers but rather small, bluish-white spots on the buccal mucosa. Behcet's syndrome (option 4) can cause oral ulcers, but they are often more widespread and associated with systemic symptoms. Therefore, the most probable cause of recurrent ulcers specifically on the gingiva and palate is herpes simplex.
