The objective of this study was to investigate the association between rheumatoid arthritis (RA) and masticatory muscles by analyzing the apparent diffusion coefficient (ADC) obtained from diffusion‐weighted magnetic resonance imaging (DW‐MRI).In this retrospective study, we analyzed data from 36 patients who underwent MRI examinations at our hospital from August 2006 to March 2022. We also included a control group consisting of 39 patients with normal TMJs who were examined during the same time frame. To compare the ADC values of the masticatory muscles between the two groups, DW‐MRI was employed.RA patients exhibited significantly higher mean ADC values in the medial and lateral pterygoid muscles compared to the control group. Receiver operating characteristic (ROC) curve analysis indicated cutoff values of 1.14, 1.15, and 1.28 for the ADC values of the masticatory muscles in RA patients, with corresponding maximum ADC under the curve values of 0.53, 0.60, and 0.65.The study revealed a notable distinction in the condition of the masticatory muscles between patients with RA and the control group, implying that the ADC measured through DWI holds promise for evaluating the association between masticatory muscles and RA. Furthermore, these findings suggest that DWI could serve as a valuable tool in identifying the presence of RA.

This study aimed to assess the apparent diffusion coefficient (ADC) values of normal salivary glands and acute submandibular sialadenitis (SS).This retrospective study included 22 patients who underwent magnetic resonance imaging (MRI) at the Nihon University School of Dentistry between February 2018 and May 2022. ADC values were compared between the acute SS and control group. Data with non‐normality confirmed by Shapiro–Wilk test was analyzed using the Mann–Whitney U test, Spearman's correlation coefficient, and a receiver operating characteristic (ROC) curve. Statistical significance was set at p < 0.05.The mean ADC values were 1.03 ± 0. 09 × 10−3 and 1.22 ± 0.17 × 10−3 mm2/s in the normal and acute SS groups, respectively (p < 0.001). ROC analysis revealed a cutoff ADC value of 1.1 for distinguishing acute SS from the normal.These findings suggest that ADC values are useful for the quantitative assessment of acute SS.

Abstract Objectives Odor is in the oral air when halitosis occurs orally. Because oral gases shrink when cooled, oral halitosis disappears when a piece of ice is placed in the patient's mouth. This physical phenomenon provides a basis for distinguishing oral from non‐oral halitosis but has yet to be quantified. Material and methods The records of 29 halitosis patients were retrospectively analyzed. Gas concentrations were measured with a portable gas detector (IBRID‐MX6) before and after cooling the mouth with 1 × 1 × 2 cm ice for 30 s. Patients were asked to rate their halitosis. Tongue temperature and oral gas concentrations were compared with paired t ‐tests and one‐way ANOVA. Results The tongue cooled by an average of 13.09°C with ice (from 36.0 to 22.4°C). The mean values of the concentrations of VOC, NH 3 , H 2 S, and H 2 decreased proportionally with cooling: 74.10%, 77.51%, 81.26%, and 96.12%, respectively. The self‐reported halitosis score decreased from 4 to 0 (n = 29, p < 0001). Conclusions It can be concluded that the ice test suppresses oral gases in sufficient quantity to detect oral halitosis.

Abstract To treat cleft lip and palate, it is critical to understand the development of the lips and face. Objective The objective of this study is to comprehend the development of lips and facial features in patients with cleft lip from birth to cheiloplasty. A comparison of incomplete and complete cleft lips was performed. Methods The morphology of the lips and face was recorded using a noncontact three‐dimensional morphology recorder from shortly after birth to cheiloplasty. For each patient, their soft tissue growth was analyzed. Results These findings suggest that an incomplete cleft widens the gap between healthy and affected sides from 2 to 3 months of age. The pattern is different from that of a complete cleft.

Abstract Background Fish bones commonly stray into the tongue base, palatine tonsils, and pharyngeal mucosa but rarely into the submandibular gland duct. Case presentation A 74‐year‐old man developed acute sialadenitis after a fish bone strayed into the submandibular gland duct. Laboratory data revealed elevated S‐amylase level; computed tomography (CT) revealed linear opacification along the submandibular gland duct. Electron microscopic analysis confirmed the object to be a fish bone; the bone discharged spontaneously prior to a scheduled excision. Conclusion Identification of foreign bodies is difficult with CT or other imaging modalities alone. Additional detailed examination, such as electron microscopy analysis, is required.

Abstract Aim Oral cGVHD is one of the phenotypes of organ involvement of cGVHD and is a complex, frequent, and highly impactful complication of allogeneic hematopoietic cell transplantation (HSCT). Few studies have compared the incidences and risk factors of oral cGVHD, and they have not been discussed. We performed to evaluate the risk factors for oral cGVHD after allogeneic HSCT in a single center. Methods A retrospective study of clinical hematological data of all consecutive patients who underwent HSCT for malignant hematologic disease and then developed oral chronic graft versus host disease (cGVHD) in a single center from 2012 to the present was performed to evaluate the risk factors for oral cGVHD. Allogeneic HSCT was performed for 179 patients. Assessment of individual risk factors (age, sex, primary diagnosis, stem cell source, human leukocyte antigen [HLA] matching, regimen, donor age, and status after remission induction therapy) was completed to identify the effects of covariates of the independent variables. Results Seventy‐two (40.2%) patients were considered to have oral cGVHD within 36 months after HSCT. Statistical analysis showed that age, sex, stem cell source, HLA matching, regimen, donor age, and status after remission induction therapy were not significant factors related to oral cGVHD, whereas the primary disease was significant. Conclusion The primary disease was a significant risk factor for oral cGVHD. The oral cGVHD was more common in myeloid neoplasms (MNs) patients than in lymphoid neoplasms (LNs) patients.

Abstract Background Dystonia has been reported as an adverse effect of antipsychotic medications; however, dentists rarely detect the symptoms because of the complexity of complaints. Case Presentation A 74‐year‐old woman presented with an open bite and jaw pain. She reported a history of depression and was being treated with medication including olanzapine. We diagnosed the patient with oromandibular dystonia. Her psychiatrist withdrew olanzapine treatment following consultation, and the open bite and jaw pain were resolved. Conclusion Dentists should consider oromandibular dystonia when a patient taking antipsychotic medication complains of an open bite. Irreversible procedures should be avoided in these patients.

Abstract Odontogenic keratocysts (OKCs) are one of the most frequently encountered cystic diseases of the jaw in clinical practice. Although OKC has been reported as a manifestation of nevoid basal cell carcinoma syndrome (Gorlin syndrome) in many pediatric patients, there have been few reports of OKC occurring in isolation. Herein, we report the case of a relatively large OKC in the mandibular body of a 7‐year‐old girl who was treated conservatively using cystectomy and open wound surgery, and the permanent teeth were unaffected. Regular check‐ups, including radiographic examinations, starting in childhood may contribute to the early detection of lesions in the maxillofacial region.

Abstract Background Submental intubation is an airway management technique wherein an endotracheal tube is guided through incisions in the floor of the mouth and the submental skin after normal orotracheal intubation. Case presentation A 20‐year‐old man with a history of pharyngeal flap construction for a cleft palate was planned for orthognathic surgery. Preoperative nasopharyngoscopy showed that the space lateral to the flap was too narrow for nasotracheal intubation; then submental intubation was performed. No intra‐ or postoperative complications were observed. Conclusion Submental intubation is a useful alternative to tracheotomy in patients with difficulty in nasotracheal intubation during surgeries requiring occlusal confirmation.
