Review
The relationship between psychoneuroimmunology (PNI) and oral health has recently garnered increasing attention due to the intricate interaction among psychological factors, the nervous system, immune responses, and oral diseases. This comprehensive review aims to elucidate the multifaceted connections between PNI and various oral conditions and conduct an in-depth analysis. Psychological factors, such as stress, anxiety, and depression, have been linked to oral microbiome alterations and immune function and the development and progression of oral diseases, such as periodontal disorders, oral ulcers, and temporomandibular disorders. Conversely, oral health conditions, particularly chronic periodontitis, have been associated with systemic inflammation, affecting mental health and overall well-being through neuroendocrine-immune pathways. Moreover, neural mechanisms, including the brain-gut axis and the autonomic nervous system, significantly influenced oral health through immune modulation and inflammatory responses. Understanding these complex interactions has implications for therapeutic interventions that target both psychological well-being and oral health outcomes. This review synthesizes current research findings from various disciplines, including immunology, neuroscience, dentistry, and psychology, to offer a comprehensive understanding of the bidirectional relationship between PNI and oral diseases. The implications of these interactions on treatment strategies, preventive measures, and interdisciplinary approaches underscore the need for integrated healthcare models that address psychological and oral health aspects to improve outcomes and quality of life in patients.

BACKGROUND
Oral implant surgery is an effective procedure for artificial implants in missing tooth areas under local anesthesia. Because patients under local anesthesia are conscious during this procedure, compared with general anesthesia-related operations, they are more likely to experience negative emotions, such as anxiety and tension. These emotional reactions result in shivering and chills in the limbs, leading to poor doctor-patient cooperation and even avoidance of treatment. In traditional Chinese medicine, it is believed that acupoint massage regulates blood and Qi, dredge menstruation, and relieve pain, which is beneficial for patients' emotional adjustment; however, there are few related clinical studies.
AIM
To observe the changes in anxiety and pain in patients with oral implant after acupoint massage combined with touch therapy.
METHODS
One hundred patients undergoing oral implantation in our hospital between May 2020 and May 2023 were randomly divided into control and study groups, according to a random number table, with 50 patients in each group. The control group received routine intervention, and the study group received acupoint massage combined with touch on the basis of the control group. Anxiety [assessed using the Modified Dental Anxiety Scale (MDAS)], pain severity, blood pressure, heart rate, and satisfaction were compared between the two groups.
RESULTS
Before intervention, the difference in MDAS score between the two groups was not significant ( > 0.05), while after the intervention, the MDAS scores decreased in both groups compared with those before the intervention ( < 0.05); the MDAS score of the study group was lower than that of the control group, with a statistically significant difference ( < 0.05). The degree of pain in the intervention group was significantly lower than that in the control group ( < 0.05). Before the intervention, there were no significant differences in systolic and diastolic blood pressures or heart rate between the two groups ( > 0.05). The systolic and diastolic blood pressures and heart rate in the intervention group, during and after the intervention, were significantly lower than those in the control group ( < 0.05). The total degree of satisfaction in the study group was significantly higher than that in the control group ( < 0.05).
CONCLUSION
Acupoint massage combined with touch better relieves anxiety and pain in patients undergoing dental implant surgery, improving the perioperative comfort of these patients and ensuring safety and a smooth operation.

BACKGROUND
This research evaluated whether the relationships between factors of resilience, self-esteem, depression, and anxiety in dental students with changes in teaching and learning methods. We also studied the psychological impact of face-to-face lectures during the COVID-19 pandemic.
METHODS
This cross-sectional descriptive study used Google Forms to collect data with the Rosenberg Self-Esteem Scale (RSE), Connor-Davidson Risk Resilience Scale (CD-RISC), Beck Anxiety Inventory (BAI), and Beck Depression Inventory (BDI and BDI-II). An open-ended question was also asked about important learning difficulties.
RESULTS
The analysis revealed very high levels of resilience (30.23 ± 5.84), self-esteem in the normal range (29.08 ± 4.03), minimal depression levels (12.32 ± 8.05), and low anxiety levels (17.20 ± 12.41). There were no significant differences between sociodemographic variables ranges in regard to all psychological questionnaires. No high levels of depression and anxiety were found.
CONCLUSIONS
The levels were low compared to other studies in which online teaching was used, which is explained by the fact that the students retained adequate resilience and self-esteem thanks to being able to contact teachers and, above all, their own peers.

There are reports of poor working conditions for early and mid-career academics (EMCAs) in universities, however, empirical data using validated tools are scarce. We conducted an online, cross-sectional survey using validated tools to assess workplace satisfaction, exposure to workplace abuse, and mental health. Participants included employees of medical and health faculties of two of the largest Australian universities, surveyed between October 2020 and January 2021.Overall, 284 participants responded. Many reported job insecurity: half (50.7%) working on contracts with less than one remaining year. Workloads were considerable, with 89.5% of participants working overtime and 54.8% reporting burnout. Workplace abuse in the forms of bullying (46.6%), sexual harassment (25.3%), sexism (49.8%) and racism (22.5%) were commonly reported. Clinically significant symptoms of depression (28.0%), anxiety (21.7%) and suicidal ideation or self-harm (13.6%) were reported; with a higher prevalence among those working more overtime, and those exposed to workplace abuse. Priorities include providing a stable and safe workplace, increasing accountability and transparency in addressing workplace abuse, and supporting professional development.In summary, EMCAs in our study were commonly exposed to precarious employment conditions and workplace abuse. Our findings provide empirical evidence on where universities and funding bodies should direct resources and change organisational risk factors, to improve workplace culture.

PeerJ 2024Gas expansion in body cavities due to pressure changes at high altitudes can cause barodontalgia. This condition may compromise flight safety.
BACKGROUND
Gas expansion in body cavities due to pressure changes at high altitudes can cause barodontalgia. This condition may compromise flight safety.
AIM
To investigate relationships among barodontalgia awareness, dental visit frequency, and barodontalgia prevalence in civilian and military pilots operating at high altitudes.
MATERIALS AND METHODS
Civilian pilots from Turkish Airlines and military pilots from the Turkish Air Force, flying between November 2022 and January 2023, participated in this study. A 20-question survey was administered to 750 pilots, covering topics such as barodontalgia awareness, dental visit frequency, breaks after dental treatments, in-flight pain, and pain type and severity. The voluntary surveys were distributed by email.
RESULTS
Of the 750 pilots, 526 completed the survey; 61% were aware of barodontalgia, and 81% of pilots who had experienced it reported pain at altitudes <2000 feet. The study revealed higher barodontalgia awareness among pilots who had experienced it, with the highest prevalence among jet pilots. Pilots with barodontalgia also showed a higher frequency of dental visits ( < 0.001). Additionally, this group reported more frequent interruption of flight due to dental treatment (IFDT), more problems experienced in flights after treatment (PFAT), and higher instances of bruxism or teeth clenching during flight, suggesting stress and anxiety ( < 0.05).
CONCLUSIONS
Barodontalgia, a type of pain linked to stress, significantly impacts pilot performance, and can threaten flight safety, even at lower altitudes. Thus, there is a need to educate pilots about stress management, barodontalgia awareness, and the importance of regular dental check-ups.

Review
Temporomandibular disorder (TMD) is a multifaceted disorder impacting the temporomandibular joint (TMJ), causing substantial discomfort and functional limitations. This systematic review aims to comprehensively assess the effectiveness of non-invasive treatment modalities for TMJ dysfunction, prioritizing a definitive protocol to ensure patient safety and enhance quality of life. Employing the PRISMA guidelines, we meticulously analyzed 20 studies from a pool of 1,417 articles sourced from databases such as PubMed, Google Scholar, ScienceDirect, and Medline. These studies underscore the multifarious nature of TMD and the varied responses to treatments such as physical therapy, laser therapy, ultrasound and electrical stimulation, splint therapy, injections, and arthrocentesis. Notably, the review highlights the paramount importance of precise diagnosis, often through surface electromyography, followed by a tailored treatment approach integrating manual therapy, counseling, and splint therapy. The systematic analysis revealed that while certain treatments such as transcutaneous electrical nerve stimulation and low-level laser therapy showed limited efficacy, combination therapies, especially those involving manual therapy, counseling, and splint therapy, demonstrated substantial improvement in reducing pain, depression, and anxiety. The findings advocate for a non-invasive, patient-centric approach, emphasizing education and symptom management before considering more invasive procedures such as injections and arthrocentesis. The review identifies the need for more comprehensive, longitudinal studies to establish a standardized, evidence-based treatment protocol for TMJ dysfunction, aiming to improve patient outcomes holistically.

PURPOSE
Primary dental care facilities and awareness about temporomandibular disorders are lacking among the indigenous population of Kerala. The aim of the study was to determine the prevalence of temporomandibular joint dysfunction (TMD) disorders among the indigenous populations of Kerala.
METHODOLOGY
This cross-sectional study included adults aged 18 years and above, visiting primary health care centre in the tribal hamlet in the town of Kalpetta, Wayanad District, Kerala, India, for reasons other than dental. Axis I and II of Research Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) was used to screen for TMD. A local language validated screening questionnaire was used. The clinical examination was carried out as per the DC/TMD by a calibrated examiner. The data was processed using SPSS and the frequencies and proportions for signs and symptoms of TMD were estimated.
RESULTS
Among 198 adults screened, 23 (11.6 %) had TMD. Among these 60 % of the adults were aged 31-65 years and predominantly females (86.9 %). 39 % of these patients were dentulous. All affected adults experienced TMD related pain for more than 3 months with 90 % of them experiencing moderate-to-severe pain. Myofascial pain was the most prevalent type. Other findings included moderate anxiety levels in 34.8 % and abnormal oral behaviour and high physical symptoms in 40 % TMD patients.
CONCLUSION
TMD disorders were prevalent among the indigenous population and remained undiagnosed. The study highlights the need for screening and the availability of basic dental care for the indigenous populations.

BACKGROUND
Detailed, comprehensive, and timely reporting on population health by underlying causes of disability and premature death is crucial to understanding and responding to complex patterns of disease and injury burden over time and across age groups, sexes, and locations. The availability of disease burden estimates can promote evidence-based interventions that enable public health researchers, policy makers, and other professionals to implement strategies that can mitigate diseases. It can also facilitate more rigorous monitoring of progress towards national and international health targets, such as the Sustainable Development Goals. For three decades, the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) has filled that need. A global network of collaborators contributed to the production of GBD 2021 by providing, reviewing, and analysing all available data. GBD estimates are updated routinely with additional data and refined analytical methods. GBD 2021 presents, for the first time, estimates of health loss due to the COVID-19 pandemic.
METHODS
The GBD 2021 disease and injury burden analysis estimated years lived with disability (YLDs), years of life lost (YLLs), disability-adjusted life-years (DALYs), and healthy life expectancy (HALE) for 371 diseases and injuries using 100 983 data sources. Data were extracted from vital registration systems, verbal autopsies, censuses, household surveys, disease-specific registries, health service contact data, and other sources. YLDs were calculated by multiplying cause-age-sex-location-year-specific prevalence of sequelae by their respective disability weights, for each disease and injury. YLLs were calculated by multiplying cause-age-sex-location-year-specific deaths by the standard life expectancy at the age that death occurred. DALYs were calculated by summing YLDs and YLLs. HALE estimates were produced using YLDs per capita and age-specific mortality rates by location, age, sex, year, and cause. 95% uncertainty intervals (UIs) were generated for all final estimates as the 2·5th and 97·5th percentiles values of 500 draws. Uncertainty was propagated at each step of the estimation process. Counts and age-standardised rates were calculated globally, for seven super-regions, 21 regions, 204 countries and territories (including 21 countries with subnational locations), and 811 subnational locations, from 1990 to 2021. Here we report data for 2010 to 2021 to highlight trends in disease burden over the past decade and through the first 2 years of the COVID-19 pandemic.
FINDINGS
Global DALYs increased from 2·63 billion (95% UI 2·44-2·85) in 2010 to 2·88 billion (2·64-3·15) in 2021 for all causes combined. Much of this increase in the number of DALYs was due to population growth and ageing, as indicated by a decrease in global age-standardised all-cause DALY rates of 14·2% (95% UI 10·7-17·3) between 2010 and 2019. Notably, however, this decrease in rates reversed during the first 2 years of the COVID-19 pandemic, with increases in global age-standardised all-cause DALY rates since 2019 of 4·1% (1·8-6·3) in 2020 and 7·2% (4·7-10·0) in 2021. In 2021, COVID-19 was the leading cause of DALYs globally (212·0 million [198·0-234·5] DALYs), followed by ischaemic heart disease (188·3 million [176·7-198·3]), neonatal disorders (186·3 million [162·3-214·9]), and stroke (160·4 million [148·0-171·7]). However, notable health gains were seen among other leading communicable, maternal, neonatal, and nutritional (CMNN) diseases. Globally between 2010 and 2021, the age-standardised DALY rates for HIV/AIDS decreased by 47·8% (43·3-51·7) and for diarrhoeal diseases decreased by 47·0% (39·9-52·9). Non-communicable diseases contributed 1·73 billion (95% UI 1·54-1·94) DALYs in 2021, with a decrease in age-standardised DALY rates since 2010 of 6·4% (95% UI 3·5-9·5). Between 2010 and 2021, among the 25 leading Level 3 causes, age-standardised DALY rates increased most substantially for anxiety disorders (16·7% [14·0-19·8]), depressive disorders (16·4% [11·9-21·3]), and diabetes (14·0% [10·0-17·4]). Age-standardised DALY rates due to injuries decreased globally by 24·0% (20·7-27·2) between 2010 and 2021, although improvements were not uniform across locations, ages, and sexes. Globally, HALE at birth improved slightly, from 61·3 years (58·6-63·6) in 2010 to 62·2 years (59·4-64·7) in 2021. However, despite this overall increase, HALE decreased by 2·2% (1·6-2·9) between 2019 and 2021.
INTERPRETATION
Putting the COVID-19 pandemic in the context of a mutually exclusive and collectively exhaustive list of causes of health loss is crucial to understanding its impact and ensuring that health funding and policy address needs at both local and global levels through cost-effective and evidence-based interventions. A global epidemiological transition remains underway. Our findings suggest that prioritising non-communicable disease prevention and treatment policies, as well as strengthening health systems, continues to be crucially important. The progress on reducing the burden of CMNN diseases must not stall; although global trends are improving, the burden of CMNN diseases remains unacceptably high. Evidence-based interventions will help save the lives of young children and mothers and improve the overall health and economic conditions of societies across the world. Governments and multilateral organisations should prioritise pandemic preparedness planning alongside efforts to reduce the burden of diseases and injuries that will strain resources in the coming decades.

Review
PURPOSE
Phenomenology is a branch of philosophy that focuses on human lived experience. Illness including dental diseases can affect this living experience. Within the dental literature, there is very little reported on the use of phenomenology compared to other healthcare sciences. Hence, the aim was to review the literature and provide an overview of various applications of phenomenology in dental research.
METHODS
This study was a narrative review using literature in the last 10 years identified by web-based search on PubMed and Scopus using keywords. A total of 33 articles that were closely related to the field and application in dentistry were included. The methodology, main results, and future research recommendations, if applicable, were extracted and reviewed.
RESULTS
The authors in this study had identified several areas such as orofacial pain and pain control research, dental anxiety, dental education, oral healthcare perceptions and access, living with dental diseases and dental treatment experience in which the phenomenological method was used to gain an in-depth understanding of the topic.
CONCLUSIONS
There are several advantages of using the phenomenological research method, such as the small sample size needed, the diverse and unique perspective that can be obtained and the ability to improve current understanding, especially from the first-person perspective.

BACKGROUND/PURPOSE
The COVID-19 pandemic has had a profound and enduring impact on various aspects of society, including medical education and the training of dental students. The field of dentistry, given its nature, is particularly susceptible to the challenges posed by a pandemic. Prolonged exposure to the pandemic is believed to have increased stress and burnout among medical and dental students. This study aimed to investigate and analyze the relationship between COVID-19 and stress, burnout, and depression in Korean dental students.
MATERIALS AND METHODS
A cross-sectional survey was conducted among 162 third and fourth-grade students from the School of Dentistry at Seoul National University. The survey comprised four main sections: general information, the Maslach Burnout Inventory (MBI), the Patient Health Questionnaire-9 (PHQ-9), and the Impact of Event Scale-Revised (IES-R).
RESULTS
The results indicated significant differences in age, study time, career satisfaction, and counseling needs between third and fourth-grade students. The fourth-grade students exhibited higher scores in the IES-R survey, PHQ-9 total score, emotional exhaustion, and depersonalization subscale items of the MBI. Furthermore, the group with abnormal responses to COVID-19 demonstrated lower levels of career satisfaction.
CONCLUSION
Fourth-grade dental students experienced higher levels of depression, vulnerability to the effects of COVID-19, and burnout. These findings highlight the need for addressing the mental health challenges faced by dental students during the COVID-19 pandemic.
