Leukemia is a malignant disease characterized by uncontrolled clonal proliferation of white blood cells. It is classified depending on clinical course of disease (acute or chronic) and the primary hematopoietic cell line affected (myeloid or lymphoid). Leukemia is often associated with orofacial manifestations, such as oral bleeding, petechiae, oral ulceration, gingival enlargement, mucosal pallor and mental nerve neuropathy. However, trismus has been rarely reported as a sign of leukemia. We present a case of trismus caused by acute lymphoblastic leukemia and emphasize the importance of orofacial manifestations in the early diagnosis of leukemia.

Pyogenic orofacial infections are most commonly odontogenic in origin. Although such infections are usually self-limiting and spatially confined, purulent material may occasionally borrow deeply into contiguous fascial space or planes far from the initial site of involvement. The incidence of orofacial infection remains low in this modern era of preventive dental care and antibiotic therapy, but severe orofacial infections are most frequently observed in the medically compromised patients. We experienced 5 cases of severe orofacial odontogenic infection associated with medical diseases, and then concluded as follows : 1. The average hospitalized period was about 5 weeks, and the signs that indicated that the infections were controlled usually appeared in third week after incision and drainage. 2. The involved medical diseases were diabetes mellitus iatrogenic Cushing's syndrome, rheumatoid arthritis, malnutrition, etc. 3. The medical diseases should be treated coincidently with control of infection.

Perforation of articular disc of temporomandibular joint is a unusual condition and diagnosed through magnetic resonance imaging (MRI), arthrography or arthroscopic surgery. We attempted to investigate the suspicious findings of articular disc perforation through examination commonly used in temporomandibular disorder (TMD) patients. We retrospectively analyzed the clinical and imaging findings of five TMD patients whose articular discs were perforated based on MRI. The most meaningful finding was the abnormal width of the joint space in cone-beam computed tomography. Thus, the clinician should perform a thorough assessment of the joint space in TMD patients and conduct additional investigation to determine what caused the abnormal joint space.

Orofacial pain is a common complaint of patients that causes distress and compromises the quality of life. It has many etiologies including trauma, interventional procedures, nerve injury, varicella-zoster (shingles), tumor, and vascular and idiopathic factors. It has been demonstrated that the sympathetic nervous system is usually involved in various orofacial pain disorders such as postherpetic neuralgia, complex regional pain syndromes, and atypical facial pain. The stellate sympathetic ganglion innervates the head, neck, and upper extremity. In this review article, the effect of stellate ganglion block and its mechanism of action in orofacial pain disorders are discussed.

It is well known that trigeminal nerve injury causes hyperexcitability in trigeminal ganglion neurons, which become sensitized. Long after trigeminal nerve damage, trigeminal spinal subnucleus caudalis and upper cervical spinal cord (C1/C2) nociceptive neurons become hyperactive and are sensitized, resulting in persistent orofacial pain. Communication between neurons and non-neuronal cells is believed to be involved in these mechanisms. In this article, the authors highlight several lines of evidence that neuron-glial cell and neuron macrophage communication have essential roles in persistent orofacial pain mechanisms associated with trigeminal nerve injury and/or orofacial inflammation.

Purpose: To assess Google Trends (GT) search behavior regarding orofacial pain (OFP) and headaches. Methods: GT scores for OFP and headache specialists between February 2013 and December 2022 were analyzed. Statistical tests such as Poisson regression analyses, mean differences, and Cohen's D were used to assess the score change over time. Results: The top three search words for OFP specialists were "temporomandibular joint (TMJ) specialist," "TMJ doctor," and "TMJ dentist," whereas the top three search words for headache specialists were "Headache specialist," "Headache doctor," and "Migraine specialist." Here, TMJ is temporomandibular joint. The GT scores for OFP specialists increased significantly (p<0.05) for all years except 2017, with the highest mean difference in 2020. The scores for headache specialists showed similar trends but gradually. Conclusions: The interest in OFP and headache specialists expressed by Google searches has increased over the years. More awareness is needed regarding the OFP scope of practice, and the use of GT may serve as an indicator.

Nasopharyngeal cancer is malignant tumor of nasopharyngeal area that is characterized of lymphadenopathy, pain, otitis media, hearing loss and cranial nerve palsy and may present symptoms similar to temporomandibular disorder such as facial pain and trismus. In this case, the patient with symptoms similar to temporomandibular disorder after surgery for otitis media presented with facial paresthesia and masticatory muscle weakness. Examinaion of trigemimal nerve was shown sensory and motor abnormaility. The patient was referred to a neurologist. Nasopharyngeal cancer was suspected on computed tomography and magnetic resonance imaging and was confirmed by biopsy. If the patient presenting with paresthesia and muscle weakness the cranial nerve examination should be performed regardless of typical temporomandibular disorder symptom. The neurologic symptom can be caused by neoplasm such as brain tumor and nasopharyngeal cancer. Nasopharyngeal cancer on rosenmuller fossa can develop otitis media. Therefore, the patient with otitis media history should be consulted to otorhinolaryngologist to examin the nasopharyngeal area.

The author studied the prevalence and sites of orofacial pain during the latest 6 months, and psychologic symptoms under the emotional stress through SCL-90-R in thirty-five dental students(nineteen men and sixteen women) of school of Dentistry, Chonbuk National University. 26 students(74.3%), 12 men and 14 women, experienced the orofacial pain; headache, toothache, facial & buccal pain, TMJ pain and intraoral pain were occurred in 51.4%, 37.1%, 25.7%, 17.1% and 17.1% respectively. In psychological scores in before-, during- and after examination, there was no significant difference between men and women. On the other hand, when these scores were compared each other in one group with orofacial pain experience and the other group without pain experience, the former showed significantly higher values in somatization, depression, hostility, and paranoid ideation dimension before examination, interpersonal sensitivity and anxiety dimension during examination, and somatization dimension after examination than those of the later group(P<0.05). The changes of psychologic symptoms in before-, during-, and after examination were observed in one group with pain experience and the other group without pain experience, respectively; in the former group the significantly higher values of anxiety dimension in during examination than after examination, and the significantly higher values of interpersonal sensitivity dimension in before examination than after examination(P<0.05) were evaluated.
