Abstract
Dental decision-making represents the establishment of a common understanding between the dental professional and the recipient of the intervention, which determines oral healthcare and dental treatment policies. Dental decision-making for persons with dementia can be challenging, and there have been no systematic reviews on this topic. Therefore, this systematic narrative review aimed to identify the current state of dental decision-making in persons with dementia. Literature search was performed using PubMed, Web of Science, Cochrane Library, CINAHL, and Google Scholar databases. Through the process of research selection, 7 articles with a high risk of bias were included in this study. This review clarified that there is limited information on the dental decision-making processes for persons with dementia. In conclusion, although this may be difficult due to different medical and socioeconomic conditions, the dilemma between the need to establish evidence for dental decision-making and medical ethics that prioritize a patient-centered position should be discussed globally in the future.

Abstract
The aim of this study was to clarify or determine any possible association between pain reports with a visual analogue scale (VAS) and a figures based scale. This research was a preliminary study aimed at developing a new pain scale without any verbal description. Healthy Japanese patients aged 20 to 39 years who received anesthetic injections for mandibular third molar extraction at our department were enrolled. Regarding pain from dental local anesthetic injections, we recorded figures selected by participants (among options of a circle, triangle, square, bar, and cross), and VAS scores. Overall, 29 men and 31 women participated in the study. Pain caused by local dental anesthesia tended to remind both men and women of the triangle among the suggested figures. Furthermore, patients who chose a cross also reported higher VAS scores than those who chose other figures. Acute pain caused by local dental anesthesia was associated with triangles, and patients who selected a cross were associated with higher VAS scores. The results of this study provide clinicians with important information for dental practice, and could prove useful in developing new pain scales.

Abstract
INTRODUCTION The aim of this systematic review was to collect evidence and recommendations for the applicability of the concept of evidence-based policy making (EBPM) during the coronavirus disease 2019 (COVID-19) pandemic and to discuss the implementation of this concept from a medical science perspective. METHODS This study was performed according to the guidelines, checklist, and flow diagram of Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020. An electronic literature search was conducted on September 20, 2022 using PubMed, Web of Science, Cochrane Library, and CINAHL databases with the following search terms: "evidence based policy making" and "infectious disease." Study eligibility assessment was performed based on the flow diagram of PRISMA 2020, and risk of bias assessment was performed using The Critical Appraisal Skills Program. RESULTS Eleven eligible articles were included in this review and divided into three groups as follows: early, middle, and late stages of the COVID-19 pandemic. Basics of COVID-19 control were suggested in the early stage. The articles published in the middle stage discussed the importance of the collection and analysis of evidence of COVID-19 from around the world for the establishment of EBPM in the COVID-19 pandemic. The articles published in the late stage discussed the collection of large amounts of high-quality data and the development of methods to analyze them, as well as emerging issues related to the COVID-19 pandemic. CONCLUSIONS This study revealed that the concept of EBPM applicable to emerging infectious disease pandemics changed between the early, middle, and late stages of the pandemic. The concept of EBPM will play an important role in medicine in the future.

Abstract
Natural disasters may affect oral health as a result of serious damage to social function and public health. However, no article has systematically summarized the impact of natural disasters on oral health. This review aimed to map the existing literature on the impact of natural disasters on oral health. Targeted literature was searched using PubMed, Web of Science, Cochrane Library, and CINAHL databases with the keywords "disaster" and "oral health." Eligibility criteria were established based on the Participant-Concept-Context model, and eligible studies were identified based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 flow diagram. Eight eligible studies related to earthquakes were included in this review. Of these, 7 studies were related to the 2011 Great East Japan Earthquake. Oral health status of victims of disaster was analyzed by assessing the following parameters: questionnaire surveys; examination for fungal infection; and analyses of the teeth, periodontal, and oral hygiene condition. Six studies suggested that natural disasters had a negative impact on oral health. Two studies could not determine the impact of natural disasters on oral health. Only 1 study analyzed the impact of disasters on oral health based on pre- and postdisaster surveys. This scoping review found that there was insufficient evidence to suggest a relationship between natural disasters and oral health and that there are biases in geographical areas and types of natural disasters in this research field. Further research is needed to promote evidence-based support by dental professionals during different disaster phases.

Abstract
The most common routes of transmission of coronavirus disease 2019 are droplet and contact infections. During dental treatment, several instruments and procedures used generate droplets of saliva and blood, such as during the extraction of an impacted third molar (M3). Surgical masks are often used during tooth extraction. However, the surface structures of surgical masks against droplets are not fully understood. Therefore, we analyzed the droplets that adhered to the surgical masks during impacted M3 extraction using electron microscopy. The surgical mask was divided into three layers and observed using electron microscopy. The outer and inner layers had a similar mesh-like structure, whereas the middle layer had a denser three-dimensional structure. Droplets ranging from 20-100 µm in size, generated during the extraction, adhered to the fibers of the outer layer of the mask. Fewer droplets adhered to the middle layer than to the outer layer. Droplets did not reach the inner layer. In conclusion, we suggest that a surgical mask can prevent droplet infection when performing impacted M3 extraction. This study is expected to contribute to the study of infection control strategies during dental treatments in the future.

Abstract
OBJECTIVE The relationship between oral and mental health has been controversial. Few studies have assessed the direct effects of oral health management on mental health and psychological disease. Using evidence from the last 5 years, this scoping review aimed to map and discuss recent progress in understanding this relationship. METHODS Electronic literature searches were performed using PubMed, Web of Science, the Cochrane Library, and the Cumulative Index to Nursing and Allied Health Literature databases. An additional manual search was performed using Google Scholar databases. Studies were selected using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 flow diagram. RESULTS An eligibility review process identified three randomized controlled trials for inclusion in this review. The oral health interventions and participants' target age, mental health status, and psychological diseases varied across these studies. The only study that reported an improvement included psychosocial support integrated with educational components of oral health as the intervention. The remaining two studies detected no significant impact of oral health interventions on mental health and psychological disease. CONCLUSIONS Evidence of the impact of oral health management on mental health and psychological disease is insufficient in studies published between 2017 and 2021.

Abstract
The coronavirus disease 2019 (COVID-19) pandemic affected the physical and mental health, socioeconomic status, and community behavior of people worldwide. The aim of this retrospective cohort study was to analyze the impact of the COVID-19 pandemic on the oral health and nutritional status of Japanese older adults based on the results of preoperative assessment in patients who underwent total hip or knee arthroplasty under general anesthesia. This study included older adults (≧65 years) who underwent total hip or knee arthroplasty in whom orthopantomography was performed for preoperative oral health assessment, during January 2019 to December 2021. Gender, age, number of family members living together, number of teeth, body mass index, and serum total protein and serum albumin levels were collected for analysis of this study. A total of 201 patients aged 65 to 89 years participated in the study. While the COVID-19 pandemic has had no impact on the oral health status, there has been a drop in serum albumin level from the results of multivariable-adjusted regression analysis considering age, gender, number of family members, and time. The COVID-19 pandemic has affected the serum albumin level of Japanese orthopedic patients aged 65 years or older.

Abstract
Pain is the most common complaint in the dental field and may have a significant impact on the patients' quality of life. However, objective pain assessment is sometimes difficult, and medical and dental clinicians may encounter cases of pain in the head and neck region, making it difficult to establish differential diagnoses. This study aimed to review acute pain in clinical dentistry at each phase of dental procedures and discuss the current status and issues in the development of acute dental pain assessment methods in the future. Acute pain in clinical dentistry may differ in nature and modifying conditions of pain at each stage: before dental procedures, while visiting dentists, and during and after dental procedures. They are related to actual or potential tissue damage, and may be modified and aided by personal experiences, including psychological and social factors. With respect to the aging and multinational population and pandemic of infectious diseases, significant breakthroughs in the development of new pain scales without verbal descriptions are desirable. Furthermore, it is expected that a new pain scale that can be applied to acute pain in the head and neck regions, including the oral cavity, will be developed.

Abstract
BACKGROUND The role of catheter-based imaging in peripheral interventions for lower extremity artery disease (LEAD) has increased with percutaneous interventions. To clarify the relation between intravascular ultrasound (IVUS) information and procedure selection strategy for endovascular treatment therapy (EVT) of the femoropopliteal artery in the real-world clinical settings wherein new endovascular technologies (NETs), including drug-coated balloon (DCB), drug-eluting stent (DES), and covered stent-graft (CS). Our retrospective multicenter analysis examined symptomatic 970 patients treated by EVT for de novo femoropopliteal lesions with IVUS guidance. The decision tree analysis was performed retrospectively to determine the association of IVUS and angiography parameters with the strategy selection of endovascular procedures. We divided the study population according to the developed tree, and identified the most popular strategy selection in each subgroup. We finally examined whether the restenosis risk would be different among respective subgroups of the tree. RESULTS During the study periods, plain old balloon angioplasty, DCB, and bare nitinol stent were most frequently selected (25.3%, 23.9%, and 23.8%, respectively). The drug-eluting stent (DES), covered stent (CS), and spot stent strategies were used in 7.3%, 11.5%, and 8.1%. NETs had the lowest restenosis risk in the overall population. The decision tree had a depth of six branches and divided the patients into 11 subgroups by IVUS and angiography parameters. The restenosis rate was similarly low among these 11 subgroups when the most popular NET in each subgroup was selected (P = 0.94). CONCLUSIONS The use of IVUS data along with angiography data would standardize the selection of endovascular procedures and can improve patency outcomes if NETs are used properly.

Abstract
The aim of this literature review was to summarize the clinical characteristics and symptoms of temporomandibular joint diseases, and to discuss the associations between temporomandibular joint diseases and categorization of malocclusion. Electronic literature searches were performed using the PubMed database. The authors established a differential diagnostic method for temporomandibular joint diseases related to malocclusion. A literature search using PubMed yielded 213 texts, of which based on exclusion criteria, 28 were included in this study. Malocclusions were categorized into 5 types. The authors suggested a diagnostic tree of temporomandibular joint diseases based on the types of malocclusion and 4 variables in clinical characteristics and symptoms. Clinicians treating malocclusions must attempt to clarify the cause of the occlusal condition. If caused by temporomandibular joint disease, it is important to make a proper differential diagnosis at first, and not to overlook the causative disease. Further clinical knowledge of associations between temporomandibular joint diseases and malocclusions should be accumulated, and the diagnostic tree should be improved based on new information.

Abstract
Lower third molar extraction is the most common surgical treatment among routine dental and oral surgical procedures. while the surgical procedures for lower third molar extraction are well established, the difficulty of tooth extraction and the frequency of postoperative complications differ depending on the patient's background. To establish a management protocol for the lower third molars, the prevalence of and risk factors for postoperative complications after lower third molar extraction were investigated in a large number of Japanese patients in a multicenter prospective study. During 6 consecutive months in 2020, 1826 lower third molar extractions were performed at the 20 participating institutions. The medical records of the patients were reviewed, and relevant data were extracted. The prevalence of and risk factors for postoperative complications were analyzed. The prevalence of postoperative complications after lower third molar extraction was 10.0%. Multivariate analysis indicated that age (≤32 vs >32, odds ratio [OR]: 1.428, 95% confidence interval [95% CI]: 1.040-1.962, P < .05), the radiographic anatomical relationship between the tooth roots and mandibular canal (overlapping of the roots and canal vs no close anatomical relationship between the roots and the superior border of the canal, OR: 2.078, 95% CI: 1.333-3.238, P < .01; overlapping of the roots and canal vs roots impinging on the superior border of the canal, OR: 1.599, 95% CI: 1.050-2.435, P < .05), and impaction depth according to the Pell and Gregory classification (position C vs position A, OR: 3.7622, 95% CI: 2.079-6.310, P < .001; position C vs position B, OR: 2.574, 95% CI: 1.574-4.210, P < .001) are significant independent risk factors for postoperative complications after lower third molar extraction. These results suggested that higher age and a deeply impacted tooth might be significant independent risk factors for postoperative complications after lower third molar extraction.

Abstract
Personal identification using dental evidence is decisive in the case of unidentified bodies because dental features, including decayed, missing and filled teeth, are unique to every individual. This review explored the possibilities and problems associated with personal identification through digital methods by the integration of telecommunications and dentistry, also known as teledentistry. Establishment of a global, objective personal identification method using dental evidence through teledentistry is desirable. However, the review reports that there are various problems that need to be resolved first, in aspects such as changes in dentition over time, technology, individual privacy and ethics. It is suggested that solving such problems and constructing a worldwide dental database for personal identification from dental images, using teledentistry, as part of social services, is a new challenge for researchers in forensic odontology and dentistry.

Abstract
Objective To examine the anatomical characteristics of impacted maxillary third molars to help predict and prevent possible adverse events during extraction. Methods This retrospective study enrolled young Japanese patients that were assessed for third molar extraction. Patients with maxillary third molar impaction presenting with no space between the maxillary second molar and the occlusal surface of the maxillary third molar were analysed using computed tomography data. Results In this study, a total of 663 patients aged 20–29 years were examined for third molar extraction and 26 teeth in 23 patients were analysed. The mean ± SD angle between the second and third molar axes was 54.2° ± 7.5° and the mean ± SD length of the maxillary third molar was 16.1 ± 1.9 mm. The maxillary third molars showed close or extensive contact with the maxillary sinus and computed tomography did not show any bone from the maxillary sinus floor. Furthermore, in all patients, the crowns of the third molars were not completely covered by the alveolar bone. Conclusions Maxillary third molars with horizontal impaction showed close or extensive contact with the maxillary sinus and their crowns were not completely covered by the alveolar bone.

Abstract
BACKGROUND Artificial intelligence is useful for building objective and rapid personal identification systems. It is important to research and develop personal identification methods as social and institutional infrastructure. A critical consideration during the coronavirus disease 2019 pandemic is that there is no contact between the subjects and personal identification systems. The aim of this study was to organize the recent 5-year development of contactless personal identification methods that use artificial intelligence. METHODS This study used a scoping review approach to map the progression of contactless personal identification systems using artificial intelligence over the past 5 years. An electronic systematic literature search was conducted using the PubMed, Web of Science, Cochrane Library, CINAHL, and IEEE Xplore databases. Studies published between January 2016 and December 2020 were included in the study. RESULTS By performing an electronic literature search, 83 articles were extracted. Based on the PRISMA flow diagram, 8 eligible articles were included in this study. These eligible articles were divided based on the analysis targets as follows: (1) face and/or body, (2) eye, and (3) forearm and/or hand. Artificial intelligence, including convolutional neural networks, contributed to the progress of research on contactless personal identification methods. CONCLUSIONS This study clarified that contactless personal identification methods using artificial intelligence have progressed and that they have used information obtained from the face and/or body, eyes, and forearm and/or hand.

Abstract
RATIONALE Adenoid cystic carcinoma (ACC) is a rare malignant tumor that primarily occurs in the salivary glands. Distant metastases can develop despite favorable local control. Moreover, distant metastasis of ACC can occur after a long time interval without local recurrence. We report the first case of ACC of the sublingual gland that developed lung metastasis 20 years after primary treatment. PATIENT CONCERNS A 52-year-old man was referred to our department with a 1-year history of painful swelling on the right oral floor. DIAGNOSIS An incisional biopsy was performed, and histopathological examination revealed malignancy. INTERVENTIONS Surgical excision of the right oral floor and right supra-omohyoid neck dissection with postoperative chemoradiation therapy were performed, and ACC of the sublingual gland was diagnosed. Left pulmonary metastasis was detected 20 years after the primary treatment. Metastasectomy was performed; however, subsequently, skin and bone metastases developed. OUTCOMES After receiving palliative care, the patient died of multiple organ failure. LESSONS As late distant metastasis of salivary ACC can develop, patients who undergo primary treatment need a long-term, strict follow-up plan even if locoregional control is favorable.

Abstract
The coronavirus disease 2019 (COVID-19) pandemic has affected various aspects, including socioeconomic status and health. This retrospective study aimed to investigate the influence of the COVID-19 pandemic on oral health based on the number of teeth that contribute to mastication, and the nutritional status of elderly patients with digestive cancers.The authors defined the before and during COVID-19 periods in this study as January 2019 to December 2019 and January 2020 to December 2020, respectively. Patients with digestive cancer who underwent general, laboratory, and orthopantomograph examinations for preoperative oral health assessment before general anesthesia participated in this study. The authors investigated the following general characteristics: (1) sex, (2) age, and (3) the organ affected by disease and scheduled for surgery under general anesthesia. The authors collected information about (4) the number of teeth that could contribute to mastication as a clinical oral health parameter. The parameters: (5) body mass index, (6) serum total protein levels, and (7) serum albumin levels were used to indicate the nutritional status.A total of 233 elderly patients with digestive cancer participated in this study. There was no significant difference between the age of the patients with digestive cancer. There was also no significant difference in the number of teeth that could contribute to mastication. Additionally, there was no significant difference in nutritional status as indicated by the body mass index, serum total protein levels, and serum albumin levels.This study showed that the COVID-19 pandemic during 2020 did not have a significant influence on the oral health and nutritional status of elderly patients with digestive cancer. However, the influence of COVID-19 on community oral health may become apparent in the future. Thus, dental professionals should continue further research regarding the effects of COVID-19 on oral health.

Abstract
Accidental ingestion of dental prostheses requires immediate emergency action. The
authors report a case of accidental ingestion of a dental prosthesis in a patient with a
disorder of consciousness. The accidental ingestion was diagnosed by imaging examination,
and the location of the dental prosthesis was explored under general anesthesia according
to the preoperative examination images. However, no dental prosthesis was found in the
hypopharyngeal region. The operators found a radiopaque region in the nasopharynx that was
suspicious of a dental prosthesis by X-ray examination of the head and neck region.
According to the X-ray examination, the dental prosthesis was removed from the
nasopharynx. The patient’s postoperative course was uneventful. Postural change for cases
of accidental ingestion of dental prostheses may be a simple and important lifesaving step
in addition to traditional methods.

Abstract
People with dementia can become missing and unable to be identified due to their cognitive decline and may not have belongings, including personally identifiable information. The aim of this systematic review was to summarise and discuss the current status of personal identification systems for missing and unidentified persons with dementia. An electronic systematic literature search was conducted by using PubMed, Web of Science, Cochrane Library, and CINAHL. By performing an electronic literature search, 128 texts were extracted. However, only three eligible texts were included in this review, and these were divided on the basis of the analysis target as follows: medical and human community support systems and digital systems. It is important to develop medical and social care systems and to construct and advance social personal identification systems, including medical and human community support systems and digital systems, for persons with dementia. However, this systematic review clarified that there have only been a few reports about the development and construction of social systems for missing and unidentified persons with dementia. People who interact with persons with dementia should consider this problem, which is increasing each year, and strive to build a social system that can be applied to personal identification as soon as possible.

Abstract
Background:Previous cohort studies showed that the use of prednisolone (PSL) was a risk factor for clinical fractures in patients with rheumatoid arthritis (RA). However, there are few reports on relationship between PSL dose and clinical fractures.Objectives:The present study aimed to determine the effect of PSL dose on the incidence of clinical fractures in the RA patients treated with PSL.Methods:We evaluated anthropoetric parameters, bone mineral density (BMD), disease activity score 28-erythrocyte sedimentation rate (DAS28-ESR), RA medication (methotrexate (MTX) dose, use of biologic disease modified anti-rheumatic-drugs (bDMARDs), and PSL dose) and the incidence of clinical fractures during nine years in RA patients who participant the TOMORROW study (UMIN000003876), which is a 10-years prospective cohort study. Data on clinical fracture was self-reported on the questionnaires. In this analysis, the data of RA patients treated with PSL at least once during nine-year period were evaluated. We analyzed the average dose of PSL until the incidence of the clinical fractures. The risk factor for clinical fractures were analyzed by using Cox proportional hazard model with adjustment for age, sex, body mass index (BMI), and smoking history.Results:We analyzed the data of 67 RA patients treated with PSL. Among them, median age was 61.8 year, 56 patients (83.6%) were female, 47 patients (70.1%) were never smoker and median disease duration was 12.1 year. The number of patients treated with PSL at baseline was 48 (69.1%). During 9 years, 23 clinical fractures were observed in 67 patients, and the incidence of clinical fracture was 0.046/person-year. In 19 patients, who were not treated with PSL at baseline but treated with PSL at least once during 9 years, 5 clinical fractures were observed. In 67 RA patients, Cox proportional hazard analysis revealed that baseline disease activities, BMD at thoracic vertebrae and medication were not significant risk factors for clinical fractures. However, average PSL dose of more than only 1 mg/day was a significant risk factor for the incidence of clinical fracture (hazard ratio (HR): 2.80; p=0.03) (Table 1).Table 1.Adjusted hazard ratio for clinical fractures in patients with rheumatoid arthritis treated with PSL.* Adjusted Hazard ratio95% Confidence intervalP valueCRP (mg/dL)1.290.88-1.910.19RF (IU/mL)0.990.99-1.000.07ACPA (U/mL)0.990.98-1.000.18DAS28-ESR0.990.71-1.390.97BMD at thoracic vertebrae (mg/cm2)0.020.00-1.000.05bDMARDs use0.550.23-1.320.18Bisphosphonate use2.330.95-5.710.07average dose of MTX (mg/week)1.020.92-1.120.74average score of DAS28-ESR1.150.76-1.750.52average dose of PSL more than 1mg/day2.81.09-7.240.03*Hazard ratio was adjusted for age, sex, body mass index (BMI), and smoking history.

Even for established RA patients, continuous use or initiation of low PSL dose was apparently significant risk factor for clinical fractures.Disclosure of Interests:Hitoshi Yoshimura: None declared, Tatsuya Koike Grant/research support from: Takeda Pharmaceutical, Mitsubishi Tanabe Pharma Corporation, Chugai Pharmaceutical, Eisai, Abbott Japan, Teijin Pharma, Banyu Pharmaceutical and Ono Pharmaceutical, Kenji Mamoto: None declared, Yuko Sugioka: None declared, Tadashi Okano: None declared, Masahiro Tada: None declared, Kentaro Inui Grant/research support from: Janssen Pharmaceutical K.K. and Astellas Pharma Inc, Hiroaki Nakamura: None declared

Abstract
BACKGROUND The careful preoperative oral assessment may be useful for safe surgery under general anesthesia. The purpose of this study was to investigate the presence of periodontitis in patients with malignant digestive disease before surgery under general anesthesia. METHODS Patients with digestive malignant disease who underwent periodontal examination and orthopantomograph examination for preoperative oral health assessment were participated. The authors investigated the patients' general characteristics and clinical oral information, including the presence of periodontitis. RESULTS One hundred twenty patients participated in this study. The mean and standard deviation of the number of teeth was 20.8 ± 8.2, and there was a statistically significant correlation between age and number of teeth. The periodontal pocket depth was 3.0 ± 1.0, and mobile teeth were observed in 62 patients. There was a statistically significant correlation between number of teeth and number of mobile teeth. However, there was no significant difference between the age of patients without mobile teeth and the age of patients with mobile teeth. CONCLUSIONS This retrospective study performed in single-institution clarified the presence of periodontitis in patients with malignant digestive disease before surgery. Regardless of age, it is important to assess the oral health, including periodontitis, for safe surgery under general anesthesia.

Abstract
Lichen planus (LP) is a chronic inflammatory mucocutaneous disease involving the oral mucosa and skin. Both oral LP (OLP) and cutaneous LP (CLP) are histopathologically characterized by dense subepithelial lymphocyte infiltrates; however, the mechanisms underlying lymphocyte recruitment to sites of LP lesions are not fully understood. Here, we assessed the induction of peripheral lymph node addressin (PNAd)-expressing high endothelial venule (HEV)-like vessels in 19 OLP and 17 CLP cases. To do so, we performed immunohistochemical staining for PNAd and CD34, followed by quantitative analysis. We also conducted triple immunohistochemistry for PNAd and either CD3 and CD20 or CD4 and CD8 to identify the lymphocyte subset preferentially recruited via HEV-like vessels. PNAd-expressing HEV-like vessels were induced in and around lymphocyte aggregates in all cases of OLP and in 10 of 17 CLP cases, and these vessels were more frequently observed in OLP relative to CLP. Although the number of T-cells attached per HEV-like vessel exceeded the number of B-cells in both OLP and CLP, the number of CD4+ T-cells attached was greater than the number of CD8+ T-cells only in OLP. These findings combined suggest that PNAd-expressing HEV-like vessels play a more important role in the pathogenesis of OLP compared with CLP.

Abstract
RATIONALE Medication-related osteonecrosis of the jaw decreases quality of life of patients with cancer. The debate about it continues regarding the risk factors, etiology, and treatment methods, and so on. Also, spontaneous regeneration of the mandible is clinically rare. PATIENT CONCERNS A 67-year-old woman presented to the authors' department complaining of pain, swelling, and pus discharge from a fistula. She previously had breast cancer bone metastases and had received antiresorptive intravenous bisphosphonate. DIAGNOSIS The patient was diagnosed with medication-related osteonecrosis of the jaw. INTERVENTIONS She received conservative therapy with antibiotics and surgical therapy as sequestrectomy under general anesthesia; however, the lesion did not heal. Thirty months after the MRONJ diagnosis, when she was 70 years' old, she underwent a left hemimandibulectomy without reconstruction under general anesthesia. OUTCOMES Spontaneous regeneration of the mandible was observed by follow-up imaging examinations. The patient has no current subjective or objective symptoms. LESSONS This is the first case report of the spontaneous mandibular regeneration after surgery for medication-related osteonecrosis of the jaw. Additionally, this case was the oldest patient among the published mandibular regeneration cases.

Abstract
Abdominal ultrasonographical and computed tomography examinations of a 12-year-old neutered female toy poodle revealed a protruding mass, approximately 2 cm in diameter, at the apex of the bladder. The mass was firm and haemorrhagic with a homogeneously brownish-yellow cut surface. Microscopically, it was unencapsulated and located in the muscle layer with invasion of the extra-muscular layer. It was composed of spindloid to oval neoplastic cells that formed irregular clefts and diffuse sheets that dissected bundles of collagen. Immunohistochemically, the neoplastic cells were positive for vimentin and lymphatic vessel endothelial hyaluronan receptor 1 antigens, but negative for cytokeratin AE1/AE3, factor VIII-related antigen, CD31, CD34, Prox-1, S100, desmin, α-smooth muscle actin and MyoD1. Negative immunolabelling for laminin antigen supported the absence of evidence of a basal lamina on ultrastructural examination. Based on these findings, this tumour was identified as a lymphangiosarcoma. To the best of our knowledge, this case is the first report of lymphangiosarcoma arising from the bladder in a dog.

Abstract
Intraoral hemorrhage is an undesirable and emergency condition, and it can also occur spontaneously. Clinicians sometimes face difficulty in identifying the hemorrhage points and the causes of hemorrhage, as well as difficulty in the hemostatic procedures. Here, the authors present two rare cases of spontaneous intraoral hemorrhage related to dental calculus. The hemorrhage points and causes of hemorrhage were determined after removing the removable intraoral components, including the dental calculus.

Abstract
Background/purpose Actinomycosis is a rare disease. It can often mimic other infectious or malignant diseases, and it is often misdiagnosed. Therefore, it is necessary to provide clinicians with clinical findings of patients with actinomycosis as many cases as possible. The aim of this study was to analyze the clinical features of actinomycosis of the orofacial soft tissues from the clinical data of the patients at the department in the past 10 years. Materials and methods A retrospective study was designed, and the general characteristics of the patients, and the clinical characteristics of actinomycosis, including the initial diagnoses, the treatment methods, and the treatment outcomes, were studied. Results Nine patients were included in the study. Initially, they were diagnosed with various diseases and treated by extraoral or intraoral surgical procedure with the administration of antibiotics. All patients were diagnosed with actinomycosis histopathologically, and lesions were cured. Conclusion The diagnoses of actinomycosis is often challenging. The histopathologic examination may provide the most valuable information for clinicians than any other examination. In most cases of actinomycosis of the orofacial soft tissues, clinicians should consider the methods of treatment along with the administration of penicillin because it is a chronic disease and usually has a good prognosis.

Abstract
RATIONALE Tooth extraction is a common dental surgical procedure. There is a possibility that various complications often occur during third molar tooth extractions. PATIENT CONCERNS The authors report herein 2 cases of migration of a high-speed dental hand-piece bur during mandibular third molar extraction-one case with the iatrogenic foreign body migrating into the mandibular body and another case with the iatrogenic foreign body migrating into the floor of mouth are reported. DIAGNOSIS The patient was diagnosed with the iatrogenic foreign body associated with mandibular third molar extraction by imaging examinations. INTERVENTIONS The authors performed elective surgery to remove the foreign body under general anesthesia in Case 1, and performed emergency surgery to remove the foreign body under local anesthesia in Case 2. OUTCOMES The foreign bodies were removed, and complete removal of the foreign bodies was confirmed by postoperative x-ray examination. The patients' postoperative courses were uneventful. LESSONS The selection of adequate surgical procedures and instruments will prevent the occurrence of iatrogenic foreign bodies. If migration accidents occur, their positions should first be confirmed by imaging examinations. Dentists and/or oral surgeons should perform removal operations considering the degree of emergency based on the results of imaging examinations.

Abstract
RATIONALE Oral liposarcoma is an extremely rare lesion that is often clinically misdiagnosed as a benign lesion because of its asymptomatic and indolent clinical course. we report a case of atypical lipomatous tumor/well-differentiated liposarcoma (ALT/WDL) of buccal mucosa, provisionally diagnosed as lipoma. PATIENT CONCERNS A 97-year-old female was referred to dentistry and oral surgery department with an asymptomatic mass on the right buccal mucosa which had been present for an unknown period of time. DIAGNOSIS Magnetic resonance imaging demonstrated a well-circumscribed lesion at the right buccal mucosa, and a lipoma was suspected. INTERVENTIONS Surgical removal was performed, and a diagnosis of ALT/WDL was made. She and her family refused additional treatment due to her age. OUTCOMES At the 10 months follow-up, the patient remained free of disease. LESSONS The indolent clinical course and small size of oral liposarcoma can lead to provisional clinical diagnosis of benign lesion.

Abstract
Periodontitis is one of the most common chronic oral inflammatory conditions worldwide and is associated with a risk of developing oral squamous cell carcinoma (OSCC). Porphyromonas gingivalis is a major pathogen in periodontitis, and its lipopolysaccharide (LPS) promotes the expression of cyclooxygenase-2 (COX-2) in OSCC both in vivo and in vitro. Celecoxib is a selective COX-2 inhibitor; however, its antitumor effects on P. gingivalis LPS-stimulated OSCC and the underlying molecular mechanism remain unclear. To elucidate the association between periodontitis and OSCC, the effect of P. gingivalis-derived LPS on OSCC cell proliferation was examined both in vitro and in vivo in the present study. The expression levels of COX-2 and p53 in OSCC cells with/without celecoxib treatment were determined via western blotting. The therapeutic potential of celecoxib in LPS-stimulated OSCC was evaluated by staining for Ki-67 and p21, as well as with terminal deoxynucleotidyl-transferase-mediated dUTP nick end labeling staining. LPS treatment significantly increased OSCC cell proliferation in vitro, and celecoxib significantly inhibited cell proliferation with/without LPS treatment. Celecoxib treatment of OSCC cells downregulated the protein expression levels of COX-2 compared with untreated cells, but there was little change in p53 expression. In the mouse xenograft model, oral administration of celecoxib significantly suppressed tumor growth, reduced the expression of Ki-67, increased the apoptosis index and induced p21 expression with/without LPS treatment. The results from the present study demonstrate that P. gingivalis' LPS can stimulate tumor growth by interacting with OSCC cells. In conclusion, these results suggest that celecoxib could be used for the effective prevention and treatment of LPS-stimulated OSCC.

Abstract
Postoperative hemorrhage after tooth extraction is a critical and clinically important issue for clinicians and patients receiving anticoagulants. The purpose of the present study was to investigate the prevalence of and risk factors for postoperative hemorrhage after lower third molar extraction in Japanese patients receiving warfarin therapy. A total of 142 patients who underwent lower third molar extraction between January 2010 and December 2016 were included, and their medical records were retrospectively reviewed. The prevalence of and risk factors for postoperative hemorrhage were investigated. The prevalence of postoperative hemorrhage after lower third molar extraction was significantly higher in patients receiving warfarin than in healthy subjects (21.8% vs 0.7%, P < 0.001). The cutoff value for PT-INR was 2.11 based on a receiver-operating characteristic analysis. A multivariate analysis indicated that an elevated PT-INR value [hazard ratio (HR) 3.798, 95% confidence interval (CI) 1.400-10.467, P < 0.01], preoperative antibiotic administration (HR 4.434, 95% CI 1.591-14.775, P < 0.01), difficulties with intraoperative hemostasis (HR 16.298, 95% CI 2.986-110.677, P < 0.01), and higher serum creatinine levels (HR 7.465, 95% CI 1.616-39.576, P < 0.05) are significant predictors of postoperative hemorrhage after lower third molar extraction. Multivariate correlations were observed between risk factors including an elevated PT-INR value, preoperative antibiotic administration, and higher serum creatinine levels, and postoperative hemorrhage after lower third molar extraction in patients receiving warfarin therapy. Clinicians need to consider these risk factors for postoperative hemorrhage after the lower third molar extraction and monitor PT-INR in patients receiving warfarin therapy.

Abstract
AIM To evaluate the clinical and molecular characteristics of hepatitis E virus (HEV) infection in Mie Prefecture, Japan, from 2004 through 2018. METHODS The clinical information of hepatitis E cases was collected from 21 medical institutions in Mie Prefecture. The nucleotide sequences of infecting HEV strains were determined for cases with available serum samples. The origins or transmission routes were inferred from phylogenetic analyses of the nucleotide sequences. RESULTS Fifty-three patients were diagnosed with HEV infection. The number of cases increased each year through 2012 and then decreased. Analyses of the clinical characteristics of the cases indicated that even mild cases were detected in the latter 10 years of the study. Nucleotide sequence analyses were undertaken on 38 of the 53 cases. The HEV subtype 3e (HEV-3e) strains identified for 13 cases were closely related to a swine HEV-3e strain that was isolated from the liver of a pig bred in Mie Prefecture. The number of cases infected with the indigenous Mie HEV-3e strains increased until 2012 but have not been reported since 2014. In the latter half of the study, cases involving various HEV strains of different genotypes and subtypes emerged. CONCLUSIONS The disappearance of indigenous Mie HEV-3e strains appeared to be the primary cause for the decrease in hepatitis E cases in Mie Prefecture. The disappearance might have been associated with improved hygienic conditions on pig farms or the closure of contaminated farms. The results suggest that indigenous HEV strains can be eradicated by appropriate management.

Abstract
RATIONALE Ossifying fibroma is benign fibro-osseous neoplasm. The authors report a case of ossifying fibroma in the mandibular angle suspected as metastasis of clear cell renal cell carcinoma. PATIENT CONCERNS A 74-year-old man presented to the primary hospital complaining of frequent urination. A tumor in the left kidney was detected via an abdominal computed tomography scan. The patient then visited the Department of Urology at our hospital. DIAGNOSES According to whole-body imaging examinations, the patient was suspected of having renal cancer with mandibular metastasis. Also, a cystic lesion of the maxilla was revealed. INTERVENTIONS Left nephrectomy was performed by urologists, and the patient was diagnosed with clear cell renal cell carcinoma of the left kidney. Approximately 1 month later, resection with a safety margin of the mandibular lesion and removal of the maxillary lesion were performed by oral and maxillofacial surgeons. OUTCOMES The patient was diagnosed with ossifying fibroma of the mandible and an odontogenic keratocyst of the maxilla via a histopathological examination. Eighteen months have passed since the operation without clinical and imaging findings associated with recurrence. LESSONS Ossifying fibroma in the mandibular angle of elderly patients is extremely rare. Surgeons should consider the possibility of metastasis when osteolytic lesions of the jaw are found in patients with cancer.

Abstract
A 2-year-old neutered female Shiba dog exhibited laboured breathing for 1 month. Computed tomography of the thoracic cavity revealed multiple nodules (2-5 mm diameter) in the lungs. Grossly, the lungs were firm and normal in shape. The nodules were grey-white in colour. Microscopically, the nodules were non-encapsulated and exhibited an irregular shape. They were composed of polygonal or spindle cells with indistinct cell borders arranged in sheets. The cells had large, round, hyperchromatic nuclei and abundant pale eosinophilic cytoplasm with no atypia. Intrapulmonary arterial emboli and infiltration into the bronchioles were observed. Immunohistochemically, the cells were positive for vimentin and negative for cytokeratin, glial fibrillary acidic protein and α-smooth muscle actin. Ultrastructurally, the cells displayed cytoplasmic processes, desmosomes and intermediate filaments. These findings led to a diagnosis of diffuse pulmonary meningotheliomatosis with sarcomatous transformation. To the best of our knowledge, this is the first report of diffuse pulmonary meningotheliomatosis in a dog.

Abstract
Oral squamous cell carcinoma (OSCC) is one of the most common malignant tumors in the oral region. Despite current therapeutic strategies, the survival rate has not been improved for several decades. Thus, it is important to develop a novel approach for the treatment of OSCC. Epigallocatechin-3-gallate (EGCG) is a major constituent of green tea and has previously been demonstrated to inhibit the growth of several types of cancer cells. However, few studies have investigated the effect of EGCG on human OSCC cells, especially in experimental animal models. The aim of the present study was to evaluate the therapeutic potential of EGCG for targeting human OSCC in vitro and in vivo. In the in vitro experiments, EGCG suppressed HSC-3 cell viability in a time- and dose-dependent manner. Cell cycle analysis revealed that EGCG induced G1 phase arrest of the tumor cells. Apoptosis was examined by Annexin V and propidium iodide staining, assays of caspase-3 and −7 activity and TdT-mediated dUTP nick end labeling (TUNEL) staining. Treatment with EGCG significantly increased caspase-3 and −7 activities, and the percentage of apoptotic cells when compared with control cells. In the in vivo xenograft experiment on mice, EGCG treatment resulted in a 45.2% reduction in tumor size as compared with the control group without weight loss. In vivo cell proliferation and apoptosis were assessed by immunohistochemical Ki-67 staining and the TUNEL staining. There were significant differences in Ki-67 expression between the EGCG treatment group and control group, and the percentage of apoptotic cells in the EGCG treatment group was significantly greater than that in the control group. These results indicated that EGCG significantly inhibited cell proliferation by affecting the cell cycle progression and apoptosis in vitro and in vivo. These findings suggest that EGCG may have clinical applications as a novel approach to oral-cancer therapy.

Abstract
Simple bone cysts (SBCs) are uncommon lesions that usually occur in the long bones of the skeleton and in the body of the mandible. Displacement of the mandibular canal due to cystic lesions have been reported previously. However, there have been no reports in which endoscopy has been utilized to observe an inferior alveolar neurovascular bundle in the lesion lumen. This current study presents a case of mandibular SBC accompanied by a floating inferior alveolar neurovascular bundle. A 13-year-old boy presented to the Department of Dentistry and Oral Surgery, University of Fukui in March 2017 with a painless swelling in the right buccal region. He was treated with fenestration surgery using the tooth extraction socket of the right mandibular third molar. An endoscopic view of the lesion lumen presented a surrounding cortical bone without an epithelial lining and the floating inferior alveolar neurovascular bundle that was consistent with the linear low signal area of the preoperative T2-weighted magnetic resonance imaging. SBC often develops in young people, and as such is minimal surgical invasion is preferable. The current case indicated that clinicians should consider the possibility of the floating inferior alveolar neurovascular bundle in the lesion and should not damage the neurovascular bundle in the narrow surgical field.
