Central sensitization represents a functional change of second order neuron induced by continuous deep pain input and maintained by psychosocial factors. When afferent neurons are involved with central sensitization, secondary hyperalgesia can appear. Secondary hyperalgesia is an increased sensitivity to stimulation without a local cause. Reports on secondary hyperalgesia to heat stimuli are relatively rare compared to mechanical stimuli. And there were few reports of secondary hyperalgesia to heat stimuli in the oral cavity. We presented a case of secondary hyperalgesia to heat stimuli in the gingival area induced by continuous odontogenic pain with a review of the related literature.

This is a retrospective study on the care of odontogenic infections in admission patients with major bleeding disorders. The study was based on a series of 514 patients treated at Dong San Medical Center, Wonju Christian Hospital and Il San Health Insurance Hospital, from Jan. 1, 2000, to Dec. 31, 2002. The obtained results were as follows : 1. The cardiovascular disease was the most frequent cause of the systemic diseases with major bleeding disorders, and liver disease, cerebrovascular disease and renal failure were next in order of frequency. But, there was the most frequent dental consultation in the liver disease, owing to the many odontogenic infectious diseases. 2. Male prediction (66.3%) was almost existed in the odontogenic infectious patients with major bleeding disorders. But, there was slight female prediction (53.4%) in the cardiovascular disease. 3. The most common age group of the odontogenic infectious patients with major bleeding disorders was the fifty decade(27.2%), followed by the forty, sixty & thirty decade in order. 4. In the contents of chief complaints on the odontogenic infectious patients with major bleeding disorder, peak incidence was occurred as toothache (42.2%), followed by intraoral bleeding, ulcer pain, dental extraction in order. 5. In the diagnosis group of odontogenic infectious diseases, periodontitis, pulpitis and periapical abscess were more common. 6. In the treatment group of odontogenic infectious diseases, the most frequent incidence(44.2%) was showed in primary endodontic drainage(pulp extirpation, occlusal reduction & canal opening drainage) and followed by the incision & drainage, the medications & oral hygiene instruction, scaling, indirect pulp capping in order.

Chronic maxillary sinusitis is a common disease, with symptoms of dull, aching pain or pressure below the eyes and signs such as tenderness over the involved sinus, whereas trigeminal neuralgia is described as severe, paroxysmal, and lancinating brief pain limited in distributions of one or more divisions of trigeminal nerve. In cases where these two non-odontogenic toothache symptoms overlaps, the diagnostic process can be confusing. Here, we report a case of a 54-year-old male patient with chief complaints of intermittent, severe, and electric-like pain in the upper left premolar and first molar area, initially diagnosed with trigeminal neuralgia but finally with maxillary sinusitis after pain recurrence 2 years after that. Therefore, thorough history taking and precise imaging interpretation should be considered to make correct diagnose especially in case of a patient with newly developed or altered or atypical symptoms.

;The Varicella zoster virus can cause two infectious diseases. The primary infection of this virus leads to Chicken pox and it goes into a latent period until it reveals itself again. When secondarily shown. it is called Herpes Zoster. Herpes Zoster can usually be seen between T-3 and L-2 of immunodepressant patients but in 13%. it is seen in the trigeminal nerve branch. During the predrominal stage. burning sensation, itching. and sharp pain can be experienced unilaterally where the nerve branch is distributed. Patients can also express tooth pain in this stage. After 2-4 days the acute stage begins with its characteristic unilateral macule showing vesicle formation. In this stage fever and fatigue can be experienced. Continuous pain even after the acute stage is called postherpetic neuralgia; deep pain and burning sensation can be expressed by the patient. The sequelae of this disease consists of rare osteomyelitis. necrosis of the jaws. or loss of teeth.teeth.

Purpose: To evaluate the clinical and radiologic findings of the postoperative maxillary cysts (POMCs) and investigate the relationship between lesion size and clinical symptoms depending on the time elapsed after radical maxillary sinus surgery. Methods: A total of 29 patients who were diagnosed with POMCs at Chonnam National University Dental Hospital were selected. Clinical and radiologic findings were investigated. POMC cases were divided into two groups: those with <24 years between maxillary sinus surgery and POMC diagnosis and those with >24 years. The chi-square test was used to compare the differences between the two groups. Results: The average period from surgery to POMC detection was 24.32 years; however, the period could not be confirmed in four patients. The average patient age was 52.75 years, and 12 (41.3%) patients were in their 50s. POMC-related clinical symptoms were as follows: buccal pain and swelling, dull pain, toothache, abscess, sensory abnormality, and asymptomatic. Twenty (69.0%) cases showed unilocular radiolucency and 9 (31.0%) revealed multilocular radiolucency. Seven cases (35.0%) were misdiagnosed as odontogenic lesions, resulting in the delayed treatment of POMCs. No statistical significance was found between the two groups with respect to symptoms, expansion to the surrounding area, presence of secondary cysts, and mesiodistal length of cyst on cone-beam computed tomography (CBCT) images. However, the buccopalatal length of the cyst on CBCT images was significantly different between the two groups. Conclusions: The buccopalatal length of POMCs observed on CBCT images was related to the time elapsed since surgery. The lack of awareness of POMCs may lead to misdiagnosis as an odontogenic infection and delayed treatment. Therefore, dentists must recognize the clinical and radiologic features of POMCs to differentiate it from dental infections.

A clinical study of selected patients with cyst which were managed in the Department of oral and maxillofacial sugery from March 1994 to February 1998 was done. An following results were obtained 1. Male were involved more than females by cyst in a ratio of 1.95:1 and most of the cases occurred in the secondary decades 2. The primary site of radicular cysts were the anterior incisor area, dentigerous cysts were anterior incisor area and canine area, incisive canal cysts were maxillary anterior area, odontogenic keratocyst were the mandibular ramus area. 3. The common symptoms were swelling(65 cases), pain(12 cases) and the mean duration of syptomatic period was 10 days. 4. The rates of histopathologic classification were radicular cyst(58%), dentigerous cyst(22%), incisive canal cyst(9%), odontogenic keratocyst(11%). 5. Average of Alk. phosphatase was 235(IU/L) at pre-twenty age and 102(IU/L) at post-twenty age. 6. In treatment modalities, enucleation was most common, odontogenic keratocyst was treated by enucleation and curettage for prevention of recurrence.

Clear cell odontogenic carcinoma (CCOC), a very rare neoplasm located mostly in the mandible, has been regarded as a benign tumor. However, due to the accumulation of case reports, CCOC has been reclassified as a malignant entity by the World Health Organization. Patients with CCOC present with regional swelling and periodontal indications with variable pain, often remaining misdiagnosed for a long period. CCOC has slow growth but aggressive behavior, requiring radical resection. Histologic analysis revealed the monophasic, biphasic, and ameloblastic types of CCOC with clear cells and a mixed combination of polygonal and palisading cells. At the molecular level, CCOC shows the expression of cytokeratin and epithelial membrane antigen, along with markers that assign CCOC to the sarcoma family. At the genetic level, Ewing sarcoma breakpoint region 1-activating transcription factor 1 fusion is regarded as the key feature for identification. Nevertheless, the scarcity of cases and dependence on histological data delay the development of an efficient therapy. Regarding the high recurrence rate and the potential of distant metastasis, further characterization of CCOC is necessary for an early and accurate diagnosis.

Hyperventilation is defined as ventilation in excess of that required to maintain normal blood $PaO_2$ and $PaCO_2$. It is produced by several distinct causes: anxiety, respiratory alkalosis, increased blood catecholamine levels, and a decrease in the level of the ionized calcium in the blood. The dental fears about acute pain, needle, drill and dental surgery lead to the severe anxiety and increased blood catecholamine level. Therefore, the most dental patient should be cared gently as the stress reduction protocol. In spite of the gentle care, two cases of hyperventilation were occurred during local anesthesia for incision and drainage of acute odontogenic infectious lesions. We suggest that the dental patients with acute odontogenic infection must be attention for the manifestation of hyperventilation, especially in the medically compromised conditions.
