ABSTRACT
INTRODUCTION: The prevalence of smoking, including heated tobacco products (HTPs), among Japanese dentists was reported to be 16.5%, significantly higher than that among Japanese physicians and United States dentists. However, large-scale studies on smoking cessation implementation based on dentists' smoking status and perceptions since the introduction of HTPs are lacking. Therefore, we aimed to investigate and assess dentists' attitudes toward smoking, including HTP use and smoking cessation, according to smoking status. METHODS: A self-administered questionnaire comprising six major items was mailed to 3883 dentists who were members of the Aichi Dental Association in August 2019. The primary outcome was smoking cessation status. The secondary outcome was the impact of smoking on intervention for smoking cessation. This study was reported using the Strengthening the Reporting of Observational Studies in Epidemiology guidelines. RESULTS: Among the 1317 (42%) dentists analyzed, men were more positive toward smoking than women. Current and former smokers were more positive about smoking than never smokers/users, regardless of the tobacco product type. Additionally, the current smoker group using conventional cigarettes was less likely to ask for their patients' smoking status than the never smoker group. Furthermore, the current smoker (OR=2.0; 95% CI: 1.3-3.1 vs never smoker) and HTP user (OR=1.9; 95% CI: 1.2-3.1 vs never user) groups were less likely to engage in smoking cessation than the never smoker/user groups, regardless of the tobacco product type. CONCLUSIONS: Since the smoking status of dentists affects the implementation of smoking cessation interventions, it is crucial to encourage them to quit using all tobacco products to promote smoking cessation interventions in dental practice. Additionally, providing proper smoking prevention education to dentists is an important task.
ABSTRACT
This study aimed to analyze post-coronectomy complications, chronological root survival rate (success rate) using Kaplan-Meier analysis, and postoperative radiographic signs for root extraction. A total of 555 mandibular third molar coronectomies were clinically and radiologically evaluated (mean follow-up period, 27.2 months; range, 1 month to 10.5 years). Complications were observed in 22 (4.0%) cases. Temporary inferior alveolar nerve damage was observed in one (0.2%) case, and 21 (3.8%) retained roots required extraction between 1 and 64 months after coronectomy due to dry socket (two cases, 0.4%), primary non-wound closure (10 cases, 1.8%), secondary root exposure (seven cases, 1.3%), and submucosal root eruption (two cases, 0.4%). Residual enamel after coronectomy was more significantly found on 13 (61.9%) of 21 extracted roots than on 30 (5.6%) of 534 surviving roots. Kaplan-Meier analysis revealed an overall survival rate of 93.8% at 5 years and 92.2% at 10 years. The 5-year survival rates differed significantly (p < 0.001) between the enamel-free (97.0%) and residual enamel-attached (58.3%) roots. The Cox proportional hazards model showed a hazard ratio of 20.87 (95% confidence interval, 8.58-50.72). The long-term outcomes of coronectomy were satisfactory, and a higher success rate is expected when the enamel is completely removed during coronectomy.
ABSTRACT
OBJECTIVE: To assess the associations between oral health status and short-term functional outcomes in hospitalized patients aged over 65 years with acute ischemic stroke. MATERIALS AND METHODS: This retrospective observational analysis included older adult patients (age, ≥ 65 years) admitted for acute ischemic stroke. The oral health status at admission was evaluated using the Oral Health Assessment Tool (OHAT). Patients were categorized into the normal oral health (OHAT score, 0-2) or poor oral health (OHAT score, ≥ 3) group. Stroke severity, Functional Oral Intake Scale (FOIS), and medical history were compared. Multivariate analysis was used to determine the association between the OHAT score and modified Rankin Scale (mRS) score at discharge, FOIS score at discharge, and length of hospital stay. RESULTS: The study comprised 129 patients (mean age: 78.8 ± 7.7 years). The poor oral health group (n = 22) had a higher stroke severity and lower FOIS scores than the normal oral health group (n = 107). The poor oral health group exhibited significantly higher rates of moderate to severe disability at discharge (odds ratio = 9.18, 95% confidence interval [CI]: 1.74-48.30, P = 0.009), lower FOIS scores at discharge (ß = -0.96, 95% CI: -1.71 to -0.20, P = 0.014), and longer hospital stays (ß = 10.70, 95% CI: 0.80-20.61, P = 0.034) than the other group. CONCLUSION: In older patients with acute ischemic stroke, poor oral health status at admission was associated with worse short-term functional outcomes, including increased disability, dysphagia, and longer hospital stay. CLINICAL RELEVANCE: Assessing and addressing the oral health status of this population can potentially improve short-term functional outcomes and enhance comprehensive stroke care.

OBJECTIVES: Therapy outcome measures (TOMs) in temporomandibular disorders (TMDs) have not been systematically evaluated. We systematically explored the main TOM assessment methods for TMD TOMs used in previous studies. DESIGN: Scoping review. DATA SOURCES: According to Preferred Reporting Items for Systematic reviews and Meta-Analysis extension for Scoping Review reporting guidelines, we systematically searched five key databases (MEDLINE/PubMed, Web of Science, Embase, Epistemonikos and ClinicalTrials) and thoroughly scanned relevant grey literature using Medical Subject Headings, Emtree and index terms. ELIGIBILITY CRITERIA: We considered primary research papers published from January 2010 to December 2020 that included patients with TMD aged ≥18 years, diagnosed according to the Diagnostic Criteria for Temporomandibular Disorders. DATA EXTRACTION AND SYNTHESIS: Four reviewers extracted general information and information on study design and setting, target, interventions, and outcome type. RESULTS: One hundred and seventy-two of the 3726 screened articles (3704 by search engines and 22 manually) were included. The TOMs analysed included pain (n=161 articles), maximal mouth opening (MMO) (91), jaw function (32), jaw movement (26), joint sound (16), quality of life (QOL) (15), depression/anxiety (14), oral QOL (10) or others (30). Evaluation periods were <4 weeks (111), <8 weeks (62), <12 weeks (59), >12 weeks (75) or 'not mentioned' (12). Pain outcomes (229) included general pain (115), tenderness (45), pain during functioning (44), resting pain (16) and others (8). Pain outcome evaluation methods included Visual Analogue Scale (VAS; 121), Numerical Rating Scale (21) and other methods (21). Pain outcome indicators were binary (10) or continuous (158); only five studies reported the least significant difference in treatment efficacy. MMO evaluation using painless methods (19) and jaw function evaluation using methods assessing mandibular movement range (23) were the most frequent. CONCLUSIONS: TMD TOMs are diverse; the major outcomes were pain, MMO, jaw function and jaw movement. Most pain outcomes are evaluated by VAS Score changes.

Total joint replacement (TJR) of the temporomandibular joint (TMJ) is a promising surgical procedure and device for treating end-stage diseases of the TMJ. For the functional and aesthetic reconstruction of the oral and maxillofacial head and neck region, TMJ TJR significantly helps maintain the patient's quality of life in terms of a better diet, mastication, speech and social interaction. TMJ TJR was approved by regulatory authorities in 2019 in Japan, thus enabling the clinical application of the TJR system. However, the surgery demands particularly difficult and high-risk procedures, necessitating the prudent selection of indicated patients. The joint committee of the Japanese Society of Oral and Maxillofacial Surgeons and Japanese Society for Temporomandibular Joint is working together to develop an appropriate clinical guideline for TMJ TJR.
ABSTRACT
Oral appliance (OAm) therapy has demonstrated efficacy in treating obstructive sleep apnea (OSA). The aim of this systematic review was to clarify the efficacy of device designs (Mono-block or Bi-block) in OAm therapy for OSA patients. We performed a meta-analysis using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system. Two studies (Mono-block OAm versus Bi-block OAm) remained eligible after applying the exclusion criteria. When comparing Mono-block OAm and Bi-block OAm, Mono-block OAm significantly reduced the apnea-hypopnea index (2.92; 95% confidence interval (95%CI), 1.26 to 4.58; p = 0.0006), and patient preference for Mono-block OAm was significantly higher (2.06; 95%CI, 1.44 to 2.06; p < 0.0001). Lowest SpO2, arousal index, non-REM stage 3, sleep efficiency, Epworth Sleepiness Scale (ESS), Snoring Scale, and side effects were not significantly different between the two groups (lowest SpO2: -11.18; 95%CI, -26.90 to 4.54; p = 0.16, arousal index: 4.40; 95%CI, -6.00 to 14.80; p = 0.41, non-REM stage 3: -2.00; 95%CI, -6.00 to 14.80; p = 0.41, sleep efficiency: -1.42, 95%CI, -4.71 to 1.86; p = 0.40, ESS: 0.12; 95%CI, -1.55 to 1.79; p = 0.89, Snoring Scale: 0.55; 95%CI, -0.73 to 1.83, p = 0.55, side effects: 1.00, 95%CI, 0.62 to 1.61, p = 1.00). In this systematic review, the use of Mono-block OAm was more effective than Bi-block OAm for OSA patients.

This systematic review clarifies the amount of effective protrusion in mandibular advancement devices of oral appliances required for obstructive sleep apnea (OSA). The systematic review adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. Review Manager 5 and GRADEpro were used to combine trials and analyze data. The present review included three studies. In mild to moderate OSA cases, measured using the apnea-hypopnea index (AHI), 50% protrusion was more effective than 75% protrusion. However, 75% protrusion was more effective for severe cases. Sleep stage, Epworth Sleepiness Scale (ESS), snoring index, and side effects significantly differed between the groups. Additionally, 75% protrusion was more effective (AHI: 0.38, 95% CI: -0.89 to 1.65, p = 0.56; sleep stage 3: -1.20, 95% CI: 9.54-7.14, p = 0.78; ESS: 1.07, 95% CI: -0.09 to 2.24, p = 0.07; snoring index: 0.09, 95% CI: 0.05-0.13, p < 0.05; side effects: RR: 1.89, 95% CI: 0.36-9.92, p = 0.45). As per the AHI, 75% protrusion was effective in severe cases, whereas 50% protrusion was effective in moderate cases. Analysis of different surrogate outcomes indicated that 75% protrusion was more effective. Further, well-designed, larger trials should determine the benefits for patients. Additionally, investigations of adherence and side effects with long-term follow-up are needed.

BACKGROUND: The Japanese Society for Dialysis Therapy established 14 clinical practice guidelines (CPGs) for various fields of renal replacement therapy. About 10 years have passed since the previous peritoneal dialysis (PD) guidelines were established. We commenced the establishment of new PD guidelines in 2016. Recently, the methods for development of CPGs have changed dramatically. SUMMARY: The previous guidelines were described in a textbook-like format. However, these kinds of guidelines no longer meet the definition of CPGs as defined by the National Academy of Medicine in the USA, according to which "CPGs are statements that include recommendations intended to optimize patient care that are informed by a systematic review of evidence and an assessment of the benefits and harms of alternative care options." Grading of Recommendations Assessment, Development and Evaluation (GRADE) is a systematic approach to rating the certainty of evidence in systematic reviews and other evidence syntheses. We have commenced the creation of new guidelines based on the same policy. The new guidelines are presented in 2 parts. Part 1 is described in a textbook-style format and includes 7 chapters, namely, Initiation of PD, Adequacy of PD, Adequate nutrition in PD patients, Evaluation of peritoneal membrane function, Discontinuation of PD for prevention of encapsulating peritoneal sclerosis, Management of peritonitis, and Management of the PD catheter and exit site. Part 2 comprises systematic reviews and recommendations on clinical questions (CQs) according to the GRADE system. Six CQs are included in Part 2: CQ1. Are renin-angiotensin inhibitors useful in the management of PD? CQ2. Is combination of icodextrin solution with glucose-based solution useful or not in the management of PD? CQ3. Is mupirocin or gentamicin ointment useful in the prevention of exit site infection? CQ4. Which method is more useful for the insertion of the PD catheter - open or laparoscopic surgery? CQ5. Intravenous or intraperitoneal administration, which route is more effective in the treatment of patients with PD-related peritonitis? CQ6. Which therapy is preferable for the management of diabetic end-stage renal failure, PD or HD? Key Messages: The new PD guidelines are under construction and will be completed by the beginning of 2019.

BACKGROUND: Dental caries (tooth decay) is one of the most common chronic childhood diseases. Caries prevalence in most industrialised countries has declined among children over the past few decades. The probable reasons for the decline are the widespread use of fluoride toothpaste, followed by artificial water fluoridation, oral health education and a slight decrease in sugar consumption overall. However, in regions without water fluoridation, fluoride supplementation for pregnant women may be an effective way to increase fluoride intake during pregnancy. If fluoride supplements taken by pregnant women improve neonatal outcomes, pregnant women with no access to a fluoridated drinking water supply can obtain the benefits of systemic fluoridation. OBJECTIVES: To evaluate the effects of women taking fluoride supplements (tablets, drops, lozenges or chewing gum) compared with no fluoride supplementation during pregnancy to prevent caries in the primary teeth of their children. SEARCH METHODS: Cochrane Oral Health's Information Specialist searched the following databases: Cochrane Oral Health's Trials Register (to 25 January 2017); the Cochrane Central Register of Controlled Trials (CENTRAL; 2016, Issue 11) in the Cochrane Library (searched 25 January 2017); MEDLINE Ovid (1946 to 25 January 2017); Embase Ovid (1980 to 25 January 2017); LILACS BIREME Virtual Health Library (Latin American and Caribbean Health Science Information database; 1982 to 25 January 2017); and CINAHL EBSCO (Cumulative Index to Nursing and Allied Health Literature; 1937 to 25 January 2017). We searched the US National Institutes of Health Ongoing Trials Register (ClinicalTrials.gov) and the World Health Organization International Clinical Trials Registry Platform for ongoing trials to 25 January 2017. No restrictions were placed on the language or date of publication when searching the electronic databases. SELECTION CRITERIA: Randomised controlled trials (RCTs) of fluoride supplements (tablets, drops, lozenges or chewing gum) administered to women during pregnancy with the aim of preventing caries in the primary teeth of their children. DATA COLLECTION AND ANALYSIS: Two review authors independently screened the titles and abstracts (when available) of all reports identified through electronic searches. Two review authors independently extracted data and assessed risk of bias, as well as evaluating overall quality of the evidence utilising the GRADE approach. We could not conduct data synthesis as only one study was included in the analysis. MAIN RESULTS: Only one RCT met the inclusion criteria for this review. This RCT showed no statistical difference on decayed or filled primary tooth surfaces (dfs) and the percentage of children with caries at 3 years (risk ratio (RR) 1.46, 95% confidence interval (CI) 0.75 to 2.85; participants = 938, very low quality of evidence) and 5 years old (RR 0.84, 95% CI 0.53 to 1.33; participants = 798, very low quality of evidence). The incidence of fluorosis at 5 years was similar between the group taking fluoride supplements (tablets) during the last 6 months of pregnancy and the placebo group. AUTHORS' CONCLUSIONS: There is no evidence that fluoride supplements taken by women during pregnancy are effective in preventing dental caries in their offspring.

PURPOSE: Studies have suggested that coronectomy reduces the risk of inferior alveolar nerve injury (IANI) when a close relationship with the inferior alveolar canal is indicated on panoramic imaging. However, the relationship between the inferior alveolar canal and the root are unclear on panoramic imaging. Our aim was to compare coronectomy with traditional extraction for the treatment of mandibular third molars that had clear high IANI risks as evaluated by dental computed tomography. PATIENTS AND METHODS: We designed a case-control study of subjects with high-risk signs of IANI on panoramic images evaluated by dental computed tomography before enrollment. The 220 patients enrolled were assigned to extraction (control group, n = 118) or coronectomy (case group, n = 102). RESULTS: The mean follow-up time was 13 months in the extraction group and 13.5 months in the coronectomy group. Six IANIs (5%) were found in the extraction group. In the coronectomy group, 1 patient (1%) had symptoms of neurapraxia, which disappeared within 1 month. Four remaining roots had signs of postoperative infection, and the patients underwent extraction of the root. No nerve damage resulted in these patients after repeat extraction. CONCLUSIONS: Coronectomy might reduce the risk of nerve injury for patients at true high risk of IANI as evaluated by dental computed tomography. A long-term postoperative review is needed to assess the incidence of root migration and the root extraction and infection rates after coronectomy.

This study was conducted in order to identify the literature on oral health status and health-related QOL, review the findings systematically, and assess the association between them. We performed a literature search of reports published between January 1973 and June 2004, using five databases including MEDLINE. Only studies that used validated generic health-related QOL instruments were selected. The reviewers evaluated selected articles independently and resolved disagreements by consensus. A total of 1,726 articles were retrieved and seven were selected for the review; five observational studies and two intervention studies. Four studies showed significant associations between oral health status and health-related QOL. Temporomandibular disorders were highly associated with reduced health-related QOL. Poor oral status linked to both craniomandibular and cervical spinal pain was associated with increased impairment of health-related QOL. Dissatisfaction with the teeth and mouth, and a sensation of dry mouth contributed to reduce health-related QOL. Providing edentulous patients with implant-supported full dentures contributed to improve health-related QOL. Assessment of health-related QOL in relation to oral health with validated instruments remains insufficient. The present findings suggest that oral health status could affect health-related QOL in some settings; however, further evidence is needed to support this interpretation.

PURPOSE: This paper is intended as an investigation of the relationship between preoperative findings and short-term outcome in third molar surgery. MATERIAL AND METHODS: We assessed 153 consecutive surgical extractions of mandibular third molars performed in 140 patients between April 1998 and March 2001. RESULTS: Fifty-four (35%) of the 153 extractions were performed in male subjects and 99 (65%) in female subjects. The median age was 27 years. The amount of facial swelling varied depending on age and sex. Severe pain was associated with depth and preoperative index of difficulty. Average pain was associated with preoperative index of difficulty. CONCLUSION: In conclusion, we consider that the short-term outcomes of third molar operations (swelling and pain) differ depending on patients' characteristics (age and sex) and preoperative index of difficulty. Further mega-trial studies of the association between preoperative findings and short-term outcome will help to elucidate the true nature and magnitude of the association.

PURPOSE: Interleukin (IL)-1A C-889T, IL-1B C-511T, IL-1B C-31T, IL-1B C3954T, and IL-1RN 86-bp VNTR (variable number of tandem repeats) are polymorphisms potentially influencing IL-1 beta production. This review summarizes 1) the biological roles of IL-1 beta, 2) allele frequencies of the polymorphisms, and 3) the reported associations between these polymorphisms and disease risk. METHODS: Papers were obtained from PubMed with keywords "IL-1, polymorphism", as well as from the references in each paper. The most relevant papers were then selected. In this review, a narrative approach was adopted. RESULTS: IL-1 beta is a multifunctional proinflammatory cytokine, whose signal is transduced through IL-1 receptor I (IL-1RI) on the cell surface. Binding levels are influenced by the IL-1 receptor antagonist (IL-1Ra), IL-1RII (decoy receptor with no signal transduction), soluble IL-1RI, and soluble IL-1RII. IL-1B encoding IL-1 beta is located on chromosome 2q14, along with IL-1A encoding IL-1 alpha and IL-1RN encoding IL-1Ra. The minor alleles, IL-1A-889T, IL-1B 3954T, and IL-1RN 2R, are rarer in Japanese than in Caucasians, while IL-1B-511T and IL-1B-31C are more frequent. These polymorphisms have been reported to have potential associations with the risk of diseases, such as stomach cancer, breast cancer, inflammatory bowel, Alzheimer's, and osteoporosis. DISCUSSION: Although there are many inconsistent findings on associations with the polymorphisms, IL-1B C-511T and the tightly linked T-31C may be useful for predicting the risk of diseases with an inflammation basis among Japanese.

BACKGROUND: Screening at industries has been advocated as a method of early detection for cancer. This study describes the prevalence of oral pre-cancerous lesions and other mucosal diseases following oral mucosal screening, and associated risk factors among Japanese industrial workers in the UK. METHODS: Oral mucosal screening was by invitation at 51 industrial locations in the UK. A self-administered questionnaire was used to record socio-behavioural factors and frequency of daily intake of fruits and vegetables. RESULTS: Four hundred and eighty-four subjects attended for oral mucosal screening (mean age 39.9 +/- 8.3 years) and their mean period of residence in UK was 5.3 +/- 4.5 years. 63.4% examined were male. 31.3% of males and 26.6% of females smoked daily. The gender differences were striking compared with Japan's national rates. A higher proportion of managerial staff was regular heavy (20+ per day) smokers. The intake of more than five portions per day of vegetables and/or fruits during the weekend was significantly higher in females than in males (P = 0.022). One hundred and six subjects (22%) were detected with oral mucosal lesions, including 16 leukoplakia lesions (3.3%) and three with oral lichen planus (1%). The rate of positive detections was higher in managers (7.5%). Odds ratios were estimated by socio-behavioural variables. Among subjects positive for oral leukoplakia, managers accounted for 68.8% (OR 5.26; 95% CI, 1.24-22.29). 87.5% of subjects detected with oral leukoplakia smoked daily and had done so for the past 10 years (OR 28.40; 95% CI, 5.63-143.28). Though regular alcohol drinking was a common feature among male leukoplakia cases, heavy alcohol misuse was not encountered. None reported an intake of five or more portions of fruits or vegetables. CONCLUSIONS: The Japanese nationals working in managerial positions in the UK and daily regular smokers in the industries visited were found to be at a high risk of oral pre-cancer. Regular dental/oral check up and tobacco education programmes are encouraged for oral cancer/pre-cancer control in industrial settings.
