BACKGROUND: This report describes four cases of cracked tooth syndrome secondary to traumatic occlusion that mimicked trigeminal @entity35900 . All @entity1 were referred by general practitioners to the Orofacial @entity158 Clinic at Nihon University Dental School for assessment of atypical @entity158 . CLINICAL PRESENTATION: Case 1: A 51-year-old @entity1 presented with severe @entity158 in the maxillary and mandibular left molars. Case 2: A 47-year-old @entity1 presented with sharp, shooting @entity158 in the maxillary left molars, which radiated to the temple and periorbital region. Case 3: A 49-year-old @entity1 presented with sharp, shooting, and stabbing @entity158 in the maxillary left molars. Case 4: A 38-year-old @entity1 presented with intense @entity158 in the left supraorbital and infraorbital areas, which radiated to the temporoparietal and maxillary regions. All cases mimicked trigeminal @entity35900 , a group of @entity12967 characterized by unilateral @entity158 and ipsilateral cranial autonomic symptoms. Trigeminal @entity35900 include @entity2686 , @entity19424 , @entity10 continua, and short-lasting unilateral @entity10 attacks with conjunctival injection and tearing/short-lasting @entity10 attacks with cranial autonomic features. @entity39 , when caused by cracked tooth syndrome, can manifest with @entity158 frequencies and durations that are unusual for @entity11624 , as was seen in these cases. CONCLUSION: Although challenging, differentiation of cracked tooth syndrome from trigeminal @entity35900 is a necessary skill for dentists.
