Article title: Pain sensitivity increases with sleep disturbance under predictable chronic mild stress in mice
Authors: Junhel Dalanon, Sachiko Chikahisa, Tetsuya Shiuchi, Noriyuki Shimizu, Parimal Chavan, Yoshitaka Suzuki, Kazuo Okura, Hiroyoshi Séi & Yoshizo Matsuka
Publication title: Scientific Reports 11:14231, 2021

Abstract:
Even though it has been well documented that stress can lead to the development of sleep disorders and the intensification of pain, their relationships have not been fully understood. The present study was aimed at investigating the effects of predictable chronic mild stress (PCMS) on sleep–wake states and pain threshold, using the PCMS rearing conditions of mesh wire (MW) and water (W) for 21 days. Exposure to PCMS decreased the amount of non-rapid eye movement (NREM) sleep during the dark phase. Moreover, the chronicity of PCMS decreased slow-wave activity (SWA) during NREM sleep in the MW and W groups in both the light and dark phases. Mechanical and aversively hot thermal hyperalgesia were more intensified in the PCMS groups than the control. Higher plasma corticosterone levels were seen in mice subjected to PCMS, whereas TNF-α expression was found higher in the hypothalamus in the W and the trigeminal ganglion in the MW group. The W group had higher expression levels of IL-6 in the thalamus as well. The PCMS paradigm decreased SWA and may have intensified mechanical and thermal hyperalgesia. The current study also suggests that rearing under PCMS may cause impaired sleep quality and heightened pain sensation to painful mechanical and aversively hot thermal stimuli.

Article title: Decreased Global Interest in Oral Cancer During the COVID-19 Pandemic
Authors: Junhel Dalanon and Yoshizo Matsuka
Publication title: Asian Pacific Journal of Cancer Prevention 22(7):2117-2124, 2021

Abstract:
Objective: Oral cancer is one of the most common malignancies in developing countries, but studies using global data are scarce. The aim of this study is to analyze the search interests for oral cancer using mouth cancer, tongue cancer, gum cancer, and lip cancer as common keywords.

Methods: Internet searches relating to oral cancer from 2010 to 2020, from 250 countries and dependent areas, were retrieved from Google Trends. Color densities in a heat map were used to show geographic differences. Kruskal-Wallis test with post hoc Dunn’s analysis was used to perform yearly comparisons of searches for mouth cancer, tongue cancer, gum cancer, and lip cancer. Search results within 2020 were also compared to determine differences. Forecasting searches from 2021 to 2022 were done by fitting time series models.

Result: From 29 of 250 (11.6%) countries, the highest search values were observed for mouth cancer in Sri Lanka, Qatar, Bangladesh, Finland, Netherlands, Spain, and France. Compared to 2020, greater searches were seen in 2018 (Mdn = 91%, P = 0.023) and 2019 (Mdn = 94%, P = 0.012) for mouth cancer, and 2019 (Mdn = 17%, P = 0.035) for lip cancer. The relative search volumes for gum cancer and lip cancer were substantially lower than mouth cancer during the COVID-19 pandemic. Conclusion: Higher-income countries tend to be more interested in seeking information about oral cancer. Noteworthy decline in the interest in seeking information online for oral cancer may have crucial implications during the COVID-19 pandemic. Google Trends offer an invaluable and inexpensive means for oral cancer surveillance and health-seeking behavior.

Article title: The Cebuano Mothers' Willingness to Pay for Dental Healthcare
Authors: Junhel Dalanon, Liz Muriel Diano, Renelson Esguerra, Ma. Paciencia Belarmino, Rodivick Docor, Omar Marianito Rodis, Rozzano Locsin, Yoshizo Matsuka
Publication title: The Journal of the Philippine Dental Association 65(2):33-37, December 2018

Abstract:
The willingness to pay (WTP) is a vital component in assessing the healthcare delivery preference of people in a socioeconomic framework. Unemployment and underemployment have dictated the ability to pay (ATP) and the income of the Filipino families. Income is a compelling indicator of WTP for healthcare. From purposively sampled participants of Cebuano mothers (n=140), this exploratory cross-sectional survey aimed to know their WTP levels for general dental healthcare and specific services through a web-based questionnaire.

Article title: An Investigation of the Filipino Dental Students' Personality Types
Authors: Junhel Dalanon and Yoshizo Matsuka
Publication title: Philippine Journal of Health Research and Development 22(2):12-17, 2018

Abstract:
Background: The Dentist Licensure Examination (DLE) is one of the most difficult pre-professional practice examinations in the Philippines. The personality type of a dental student can be a determining factor or a testfor-fit of the chosen college program, the DLE, and the eventual profession.

Objectives: This study aimed to document the personality dichotomies and MBTI personality categories of the respondents.

Methods: Through the Myers Briggs Type Indicator (MBTI), this cross-sectional investigation examined the Filipino students' personality type in a dental school in the Philippines and presented it through descriptive statistics.

Results: In retrospect to the personality dichotomies, majority or 44 (17.19%) of the students were of the introverted feeling with intuition variety or the Introversion Intuition Feeling Perceiving (INFP) type. This personality type does not coincide with that of a dentist or dental student in other studies.

Conclusion: The mainstream dental students' personality types were inclined to traits that are indicative of the INFP professions (e.g. artists, counselors, social workers, etc.) and not of a prospective dentist. These findings will add to the database of dental education in the Philippines, and will enable the dental educators and schools to improve their educational strategies.

Article title: The role of chemical transmitters in neuron-glia interaction and pain in sensory ganglion
Authors: Yoshizo Matsukaa, Shaista Afroz, Junhel C. Dalanon, Takuma Iwasa, Arief Waskitho, Masamitsu Oshima
Publication title: Neuroscience & Biobehavioral Reviews 108, 2019

Abstract:
Neuropathic pain (NP) develops because of damage to the peripheral or central nervous system. It results in the hyperalgesia and allodynia. In the recent years, various researchers have studied the involvement of neuro-immune system in causing persistence of pain. The absence of synaptic contacts in the sensory ganglion makes them distinctive in terms of pain related signalling. In sensory ganglia, the neurotransmitters or the other modulators such as inflammatory substances produced by the ganglion cells, because of an injury, are responsible for the cross-excitation between neurons and neuron-glial interaction, thus affecting chemical transmission. This chemical transmission is considered mainly responsible for the chronicity and the persistent nature of neuropathic pain. This review examines the pain signalling due to neurotransmitter or cytokine release within the sensory ganglia. The specific areas focused on include: 1) the role of neurotransmitters released from the somata of sensory neurons in pain, 2) neuron-glia interaction and 3) role of cytokines in neuromodulation and pain.

Article title: Organizational Dilemma: Dental Faculty Acquisition In The Philippines
Authors: Junhel Dalanon, Aldwin Joseph Gimena, Alrine Carmellus Arreza, Joyce Anne Jalbuna, Larissa Salinas, Mia Tumamac, Ma. Paciencia Belarmino, Renelson Esguerra, Rodivick Docor, Nami Goto, Yoshizo Matsuka
Publication title: IOSR Journal of Business and Management 20(3):65-71, 2018

Abstract:
In the dental academe, much like in every field of work and expertise, the need for adequate manpower has been a key to function. In a third-world country like the Philippines, there are underlying factors that make it even more difficult to acquire manpower in an organization. There are challenges in meeting the demands for future dental faculty. In October 2016, a cross-sectional survey was utilized to evaluate the perception of the respondents' regarding the challenges in hiring new dental faculty members in a dental college in the Philippines. A standardized survey form was used to gauge the different domains of the challenges in meeting the demands for future dental faculty. A negative connotation on the overall appearance of the university, research grants, research assistance, and research resources, suggest that improvements should be done to make the teaching jobs in the dental college more appealing to prospective applicants.

Publication title: Dental Access 4(1), 2018

Abstract:
Regardless of the superiority of your composite filling material, you can’t completely do away with microleakage and material deformation. Irrespective of the morphologic feature and osseointegration attributes of your dental implant, a marginal bone loss will still exist. Caries prevalence is still high at 87.4% according to the 2011 National Monitoring and Epidemiological Dental Survey (NMEDS). That is why we need a miracle cure.

Publication title: IOSR Journal of Dental and Medical Sciences 17(2), February 2018

Abstract:
Background: The technology acceptance model (TAM) has been used to gauge the use of information technology (IT) in healthcare. Incrementally, dentists and dental students of developing nations have been using IT through patient management software.

Materials and methods: With a response rate of the participants at 100%, composed of 90 junior and senior dental interns, selected through purposive sampling, this cross-sectional survey gauged the perceived ease of use and perceived usefulness of a dental patient management software in a dental school in the Philippines. This survey utilized a standardized questionnaire after the participants were made to use the software.

Results: The dental students perceived the dental patient management software to be quite useful (wm=5.99) and extremely easy to use (wm=6.22). A significant relationship also exists between perceived usefulness and perceived ease of use of the patient management software (0.45322).

Conclusion: The dental students perceived the dental patient management software to be useful and easy to use in the dental infirmary of this dental school. TAM is also implicated to be a useful model and a determinant of the dental students perceived ease of use and perceived usefulness of the IT healthcare device. This study supports and contributes to the TAM in the healthcare setting.

Article title: The State of Professional Development of Filipino Dentists
Authors: Junhel Dalanon, Gantumur Chimeddulam, Yoshizo Matsuka
Publication title: Dental Access 3(4), 2017

Abstract:
It wasn’t long ago that the Philippines had the most number of dental schools in Asia. Before World War II, the Philippines had 10, India and Japan had 7, Indonesia had 3, Pakistan had 2, while Thailand and Korea had 1 each. The first Philippine dental school was the Philippine Dental College (1913) and the first dental school outside of the capital was Southwestern Colleges (1946) in Cebu City. Doing your practice in the country was also less complicated back then. You study dentistry, you pass a written exam, you can put up a dental clinic, and start treating patients. Nowadays, an aspiring dentist in the Philippines will have to study 2 years of pre-dental education and 4 years of dental proper education leading to a Doctor of Dental Medicine degree (DMD), according to the Commission on Higher Education Memorandum Order (CMO) No. 33 series of 2006. Furthermore, a rigorous dentist licensure exam (DLE) composing of a written phase and a practical phase will need to be taken and passed according to Republic Act (RA) 9484.
