AIM
A healthy diet could help to prevent both oral and systemic diseases, with dentists and nutritionists supplementing their skills. The dental setting, where patients periodically refer to seeking oral health care, represents a powerful opportunity for nutritional counselling. To the best of our knowledge, no study is available on patients' attitudes towards dietary counselling in the dental setting. This cross-sectional study investigates patients' attitude towards receiving nutritional support within the dental setting and it elucidates whether a transdisciplinary approach would be well accepted.
MATERIALS AND METHODS
A questionnaire was administered to patients attending three different clinics: a private clinic, a hospital dental clinic of the national healthcare system and the private dental practice within the same hospital.
RESULTS
Three hundred thirteen questionnaires were collected. Most dental patients acknowledged receiving nutritional advice from both dentists and nutritionists. The nutritionist within the dental setting was positively perceived, providing useful advice to prevent oral and systemic diseases and also drawing up a diet with periodic follow-ups.
DISCUSSION AND CONCLUSION
These findings support the positive attitude of patients towards receiving nutritional counselling within the dental setting. The dental clinics can be pivotal in oral and systemic disease screening and prevention and a multidisciplinary approach is highly encouraged.

Journal of Dentistry Jun 2024The aim of this study was to evaluate the use and reintervention rate of fillings compared to preformed metal crowns in the everyday clinical practice of German dentists.
OBJECTIVE
The aim of this study was to evaluate the use and reintervention rate of fillings compared to preformed metal crowns in the everyday clinical practice of German dentists.
METHODS
In this retrospective, longitudinal analysis, fee codes from the Kassenzahnärztliche Vereinigung Westfalen-Lippe for restorations placed in primary molars between 2012 and 2015 in children until 7 years of age followed for a 7-year period (latest until December 2022) were filtered and analyzed with the Fine and Gray competing risk regression and Cox proportional hazards regression to calculate the risk of reintervention divided into the main outcomes "Successful", "Minor Failure/Repair" and "Major Failure/Endodontic Treatment/Extraction". 367,139 primary molars (one-surface fillings: n = 117,721; two-surface fillings n = 198,815; three-surface fillings n = 36,695; more than three-surface fillings n = 8,267 and preformed metal crowns n = 5,641 were included in this study.
RESULTS
Teeth treated with preformed crowns needed significantly less re-interventions. Subdistribution hazard ratio for minor events was 0.117 (95 %-CI: 0.097 to 0.141) and hazard ratio of major events (HR=0.786; 95 %-CI: 0.695 to 0.890) when compared to one-surface fillings in multivariable adjusted analysis. Within 7-year follow-up preformed crowns required less repairs (80.6 % success rate, minor failure 4.4 %, major failure 16.3 %) than the teeth treated with composite fillings (46.2 %-52.6 % success rate, minor failure 27.0 %-39.5 %, major failure 15.5 %-28.4 %, p < 0.001).
CONCLUSION
Within the German healthcare system fillings are the first choice for treating primary molars despite considerably higher reintervention rates. This encourages a discussion on the indication of fillings and the more durable preformed metal crowns to reduce unnecessary reintervention in young children.
CLINICAL SIGNIFICANCE
This study gives an unprecedented insight into the German healthcare system regarding the reintervention rates of the most relevant treatment techniques for caries in primary molars.

The Impact of Repeated Steam Sterilization Cycles on the Efficacy of Chairside Adjustment Kits for Polishing Monolithic Multi-Layered Zirconia Dental Restoration Material.
BACKGROUND Before insertion, chairside adjustment kits are heat sterilized for positioning and polishing dental restorations. This study aimed to evaluate the effects of 2 steam sterilization cycles on the efficacy of polishing highly translucent monolithic zirconia (HTMLZ) dental restoration material. MATERIAL AND METHODS 100 HTMLZ disc-shaped specimens were adjusted (grinding, finishing, polishing) with EVE Diacera kit. Two steam sterilization techniques [standard (Gp S), immediate/flash (Gp (F)] of CAK were further subgrouped based on number of sterilization cycles [cycle 1 (control), cycle 5, 10, 15, and 20 (experimental)] (n=10 each). Each subgroup accordingly was evaluated for average surface roughness (Ra) and root mean square roughness (Rq) using a profilometer. Mean and standard deviation of 5 subgroups were statistically analyzed using one-way ANOVA/post hoc Tukey's test. Scanning electron microscopy complemented Ra, Rq measurements. Statistical differences of P≤0.05 were considered significant. RESULTS HTMLZ specimens in both groups showed increased (Ra/Rq) values after repeated sterilization of EVE Diacera kit, with Gp F showing lesser increase than Gp S (20 cycles). Gp F at 10 cycles and Gp S at 15 cycles showed clinically unacceptable roughness threshold (0.25 μm). Differences between subgroups for Ra and Rq values were significant (P≤0.05) with less differences within groups observed in early cycles (1, 10). Results validate the manufacturer's recommendations of using flash sterilization/10 cycles for EVE Diacera kit. CONCLUSIONS Repeated sterilization reduces efficacy of chairside adjustment kit to produce smooth surfaces on HTMLZ. This study recommends flash sterilization to a maximum of 10 times to get the clinically acceptable results of Ra and Rq.

Immuno-histochemical evaluation of CD34 in oral lichen planus (OLP) and Oral Submucous Fibrosis (OSMF) is of interest to dentist.20 specimens of normal oral mucosa (buccal mucosa/gingiva tissue) from patients who had extractions performed as part of orthodontic treatment comprised Group I, the control group. Group II comprised 30 individuals with a diagnosis of oral lichen planus. 30 OSMF cases with diagnoses is Group III. These 80 specimens were all given consideration when choosing for CD34immuno-histochemical staining. The CD34 was greater in all categories of OLP and OSMF when compared to normal controls. Maximum CD34 expression was observed in erosive OLP (147.41±17.60) followed by OSMF (116.01 ±11.72) and reticular OLP (105.01±11.62). Data was statistically significant (p<0.001).Immunohistochemistry of CD34 evaluation is a potential diagnostic marker for OLP and OSMF.

Review
Bioterrorism involves the deliberate release of harmful biological agents, such as bacteria and viruses, aimed at causing mass casualties within a population. Often referred to as "poor man's nuclear weapons," chemical and biological weapons pose a significant threat due to their potential for mass destruction. Detecting and preventing bioterrorist attacks is challenging, making them one of the most feared scenarios. Dentistry plays a crucial role in responding to bioterrorism and other catastrophic events, leveraging its personnel and facilities effectively. This paper explores the signs and symptoms of biological agents used in mass destruction, as well as the oral and dental manifestations of both naturally occurring and bioengineered infectious agents. Furthermore, the article stresses the importance of countermeasures against bioterrorism, including deterrence, prevention, surveillance, medical management, and training. Emphasis is placed on implementing surveillance systems, bolstering medical readiness, and conducting training programs to effectively detect, assess, and respond to bioterrorism threats. Ultimately, the article underscores the critical role of dentists and healthcare professionals in collaborative efforts to mitigate the impacts of bioterrorism through proactive measures.

Molars have been observed to have a variety of morphological forms. The least understood and most treatable tooth in the posterior region is the upper first molar. The maxillary first molar has a complex anatomy with a wide variation in the number, size, and shape of the root canals. The case documentation highlights the endodontic treatment of the upper first molar with an anomalous position of the mesiobuccal 2 (MB2) canal. Endodontic therapy success is contingent upon the awareness of the dentist about the differences i.e. morphology and outline of the root and its canal.

Taiwan has implemented a Medical Home Healthcare (MHHC) policy to provide home healthcare services to residents in need. First was the Ordinary Medical Home Healthcare (OMHHC) program in 1997 and then expanded to Integrated Medical Home Healthcare (IMHHC) in 2016. The OMHHC is provided care for residents with tubes at home or in institutions by physicians and nurses, and the IMHHC include additional professions, such as pharmacists and dentists. This study analyzed the longitudinal data from 2013 to 2020 with respect to overall home health services utilizations, and the type of services, and compared the differences between areas with and without healthcare shortages. Our results showed that the IMHHC program enhanced the accessibility of home healthcare to those in needs, especially those in healthcare shortage areas. However, some services in the IMHHC program may still have low utilization rates. It is necessary to investigate the potential barriers for residents to access those services.

Review
OBJECTIVES
Dentists' diagnostic accuracy in detecting periapical radiolucency varies considerably. This systematic review and meta-analysis aimed to investigate the accuracy of artificial intelligence (AI) for detecting periapical radiolucency.
DATA
Studies reporting diagnostic accuracy and utilizing AI for periapical radiolucency detection, published until November 2023, were eligible for inclusion. Meta-analysis was conducted using the online MetaDTA Tool to calculate pooled sensitivity and specificity. Risk of bias was evaluated using QUADAS-2.
SOURCES
A comprehensive search was conducted in PubMed/MEDLINE, ScienceDirect, and Institute of Electrical and Electronics Engineers (IEEE) Xplore databases. Studies reporting diagnostic accuracy and utilizing AI tools for periapical radiolucency detection, published until November 2023, were eligible for inclusion.
STUDY SELECTION
We identified 210 articles, of which 24 met the criteria for inclusion in the review. All but one study used one type of convolutional neural network. The body of evidence comes with an overall unclear to high risk of bias and several applicability concerns. Four of the twenty-four studies were included in a meta-analysis. AI showed a pooled sensitivity and specificity of 0.94 (95 % CI = 0.90-0.96) and 0.96 (95 % CI = 0.91-0.98), respectively.
CONCLUSIONS
AI demonstrated high specificity and sensitivity for detecting periapical radiolucencies. However, the current landscape suggests a need for diverse study designs beyond traditional diagnostic accuracy studies. Prospective real-life randomized controlled trials using heterogeneous data are needed to demonstrate the true value of AI.
CLINICAL SIGNIFICANCE
Artificial intelligence tools seem to have the potential to support detecting periapical radiolucencies on imagery. Notably, nearly all studies did not test fully fledged software systems but measured the mere accuracy of AI models in diagnostic accuracy studies. The true value of currently available AI-based software for lesion detection on both 2D and 3D radiographs remains uncertain.

BACKGROUND
This study adopts a novel approach of using single-item surveys to simplify the assessment of oral health status and behaviors among Japanese private sector employees. We aimed to establish the validity of self-reported oral health in relation to clinical dental examinations, and to elucidate the relationship between oral diseases, health behaviors, and self-assessments. A secondary aim was to explore the association of self-rated oral health with oral health behaviors.
MATERIALS AND METHODS
Self-administered questionnaires and dental examinations were obtained from 2262 Japanese private sector employees. Workers self-rated their overall oral health status according to five choices: "very good," "good," "fair," "poor," or "bad." Self-reports were then compared with the results of clinical dental examinations, which included measuring the oral hygiene index (DI-S), the number of decayed teeth, periodontal status (Community Periodontal Index) and number of missing teeth. Convergent validity was also tested by examining the correlations of self-reported oral health status with oral health behaviors.
RESULTS
Overall, 30.8% of workers reported their oral health as "poor" or "bad." "Poor" or "bad" oral health status was significantly correlated with missing teeth, periodontitis, and decayed teeth. However, lower correlations were found for gingivitis and the oral hygiene index. Most self-reported oral health behaviors were correlated with self-rated oral health; exceptions were "tooth brushing instructions received in a dental clinic," "having a primary-care dentist," and "habitual snacking between meals."
CONCLUSIONS
Self-rated oral health provides reasonably valid data, and correlated well with clinically assessed oral health status, including dental caries, periodontal status, and tooth loss. Convergent validity was also found for oral health behaviors.

Introduction of a Multidisciplinary Preoperative Clinic at Juntendo University Hospital - A Retrospective Observational Study Focusing on Effects of Preoperative Interventions on Clinical Outcomes.
OBJECTIVES
To investigate the effects of interventions provided by a multidisciplinary team consisting of anesthesiologists, dentists, pharmacists, and nurses at a Preoperative Clinic (POC) on postoperative outcomes.
METHODS
We retrospectively investigated patients who underwent preoperative evaluation at the POC at Juntendo University Hospital between May and July, 2019. Patients were divided into intervention and non-intervention groups according to whether they received intervention(s) at the POC or not. Postoperative outcomes were compared between the groups, before and after propensity score (PS) matching.
RESULTS
We investigated 909 patients who completed POC evaluation and underwent surgery. Patients in the intervention group (n = 455 [50.1%]) received at least one intervention delivered, in the order of higher delivery frequencies, by dentists, pharmacists, nurses, and anesthesiologists. Before PS matching, the intervention group was associated with older age, more frequent cardiovascular comorbidities, and higher ASA-PS grades than the non-intervention group, while neither frequencies nor severities of postoperative complications differed between the groups. These outcomes did not differ between 382 PS-matched pairs with comparable risk factors either.
CONCLUSIONS
Before PS matching, postoperative outcomes did not differ between the groups, although the intervention group was associated with higher risks. These suggested that POC interventions could have improved postoperative outcomes in the higher-risk intervention group to the same level as in the non-intervention group. However, such potential beneficial effects of interventions could not be proven after PS matching. Further studies are required to elucidate effects of POC interventions on postoperative outcomes.
