Background: This study evaluated pulp vitality of anterior permanent teeth using pulse oximetry (PO), which is already used for monitoring of patient's $SpO_2$ and pulse rates (PR). Also we compared with ice tests and electric pulp test (EPT). Methods: 9 teeth, endodontic treated, were selected as non-vital teeth group. 17 vital teeth were selected as control group. Our aim is to compare sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of ice test, electric pulp test and pulse oximetry, respectively. Pulse oximetry has two test results, $SpO_2$ and pulse rates. Also we calculated correlation and statistical significances by Pearson's test between EPT and pulse oximetry. Results: Sensitivity, specificity, PPV, NPV were calculated on each tests. Ice test has results of 1.00, 0.89, 0.94 and 1.00, respectively. EPT has results of 0.94, 0.78, 0.89 and 0.88 respectively. $SpO_2$ has results of 0.94, 1.00, 1.00 and 0.90, respectively. PR has results of all 1.00. Conclusions: PO showed relatively accurate, stable and objective results on both $SpO_2$ and PR. Percentage of ability of accurate diagnosis for vital teeth is 94% for ice test, 89% for EPT, 100% for $SpO_2$ and PR. Percentage of ability of accurate diagnosis for non-vital teeth is 100% for ice test, 88% for EPT, 90% for $SpO_2$ and 100% for PR. In additions, PR could be more accurate and significant tests than $SpO_2$.
The Importance of Early Diagnosis of Diffuse Large B-cell Lymphoma in the Jaw: Case Reports

Lymphoma, which accounts for 3.5% of all oral cancers, is further divided into Hodgkin's lymphoma (HL) and non-Hodgkin's lymphoma (NHL). NHL accounts for 96% of lymphomas, and diffuse large B-cell lymphoma (DLBCL) is the most common subtype accounting for 32% of NHL. In the oral cavity, extra-nodal non-Hodgkin's lymphoma may develop in the dentoalveolar region of the maxilla or mandible. It can also mimic inflammatory lesions that occur around periodontal tissues, such as periapical granuloma and chronic osteomyelitis. Misdiagnosis of jaw lymphoma can delay appropriate treatments and worsen the prognosis. Therefore, to avoid delay in diagnosis, clinicians should identify the possible malignancy based on unusual symptoms, clinical findings, radiographic examinations, and histopathological evaluation. We present two cases of DLBCL in the right posterior mandible of a 64-year-old man who was initially misdiagnosed as acute apical abscess and in the right posterior maxilla of an 81-year-old woman who was initially misdiagnosed as chronic periodontitis. These cases demonstrate that it is important for both pathologists and clinicians to consider malignant lesions such as lymphomas in the differential diagnosis of apical radiolucency.

Lateral facial cleft is relatively rare congenital malformation, which is known as macrostomia. Tessier’s No. 7 facial cleft is also another rare form, which varies from a simple widening oral commissure to a complete fissure extending toward the external ear. Especially for this lateral facial cleft repair, several operation techniques can be used. But there are no standardized or recommended approach methods up to date. The purpose of this article is to review of surgical approaches for the lateral facial cleft including the facial cleft number 7 of Tessier’s classifications. During last several years, authors have experienced 15 cases of lateral facial cleft in Vietnam, Jordan, India and Ghana. And we used direct closure with straight line or W plasty, Pfeifer wavy incision, multiple Z plasty flap, geometrical designed flap and so on. The appropriate incision design for lateral facial cleft could be suggested with several consideration factors, such as unilateral or bilateral, combined with other facial defect, skin color, commissure contour and other functional disturbances. The lip commissure with only one linear scar can be achieved after determining the lost commissure location like the opposite normal commissure as a guide in the unilateral facial cleft patient. And the new commissure site can be determined by deciding the transition line between the color of the lip mucosa and that of the deeper buccal mucosa in the bilateral facial cleft cases. For the better understanding of lateral facial cleft management as a routine esthetic and functional reconstructive procedure, the various surgical approaches were reviewed and summarized in this article.
Implant Placement on a Cementoosseous Dysplastic Mandible with a Long-term Follow-up: A Case Report
이원욱,도지원,권익재 대한구강악안면임플란트학회 2023 대한구강악안면임프란트학회지 Vol.27 No.3
Among various benign fibro-osseous (BFO) lesions, cemento-osseous dysplasia (COD) is the most prevalent pathology. Placement of implants in the BFO tissue, especially in a jaw with COD, often presents clinical concerns. In this case report, we present an instance of complete removal of COD followed by bone grafting, and subsequent implant placement after confirming the restoration of normal bone structure. Radiographs confirmed that the implant and normal bone could be maintained without any problems during the long-term follow-up period. The area where COD was removed was filled with collagen material or xenogenic bone and replaced with normal bone. Therefore, if the COD lesion is removed from the area, replaced with normal bone, and an implant is placed, reasonable and stable outcomes can be anticipated.

Microstomia is caused by congenital growth abnormalities, exposure to electricity or chemicals, or direct burns. In the case of burn-induced microstomia, treatment is difficult because of fibrosis at the burn site. During dental treatment, buccal retraction is necessary to access the posterior teeth. When performing maxillary sinus augmentation using the lateral approach, sufficient buccal retraction through the buccal vestibule is required. Implant placement with sinus augmentation in patients with burn-induced microstomia caused by is very difficult to treat. Herein, we describe the successful results of simultaneous bilateral sinus augmentation and implant placement along with commissuroplasty and upper
