Apart from dental and periodontal diseases, oral mucosal lesions are also frequently encountered by both general dentists and dental specialists in outpatient clinics. Although these soft tissue lesions may only reveal a localized issue, sometimes they may be the only sign of a more serious underlying systemic condition. Thus, oral ulcerations pose a unique diagnostic challenge for healthcare providers and should be cautiously handled when they last for more than two weeks, even after any possible traumatic etiologies are eliminated. There are many different classifications regarding oral ulcerations based on their etiologic or clinical features. In order to provide a logical and simple stepwise guidance to accurate diagnosis, this chapter will categorize and explain these lesions based on their clinical properties.

In the field of dentistry, diagnoses based on data obtained using medical imaging modalities such as digital panoramic radiography and cone beam computed tomography (CBCT) have been widely recommended for advanced dental care. In Lao People’s Democratic Republic (Laos), there are place where advanced dental imaging devices are available in only one university dental hospital. The establishment of an information and communication technology (ICT) system has been expected as telemedicine system, for sharing medical imaging data among medical institutions in Laos. Recently, regional medical cooperation using telemedicine has been developed in Japan, and medical imaging data have been provided and shared among medical institutions, by using a mobile tablet terminal application. Therefore, we have carried out the empirical research on the telemedicine system with the university in Laos. The technologies and research results from our project will be presented in this chapter.

Osseointegrated implants have been an optimal treatment option for dental rehabilitation of fully or partially edentulous patients. Although peri-implantitis remains as the most common local risk factor for dental implant failure, the development of oral cancer involving the soft tissue around the titanium may lead to early implants loss and impact the quality of life of the patient negatively. Oral squamous cell carcinoma (OSCC) is the most common malignancy among head and neck tumors. It has higher prevalence in men over 50 years old, and in tobacco and/or alcohol users. Unfortunately, oral cancer is often detected in advanced stages, when the treatment options are limited. Thus, OSCC typically has poor prognosis. Despite the recent advances in oral carcinogenesis understanding, the relationship between dental implants and the development of malignant lesions around them is not completely understood. It has been suggested that the titanium corrosion occurring at the top of dental implants causes the release of metal ions. These ions might lead to oral epithelial genetic damage and higher susceptibility of normal mucosa to malignant transformation. The aim of this chapter was to review the clinical characteristics, diagnosis, and the possible carcinogenic mechanisms involved in oral cancer around dental implants.

To improve the efficiency of the dental care service system in Thailand. To synthesize content from Khon Kaen University (KKU) staffs and students’ research and presentations from 1984 to 2020 about oral health hygiene and related diseases. Sixteen publications and presentations by KKU staffs and their students about oral health problems and management were retrieved, reviewed and analyzed. Poor oral health of people in the northeast of Thailand is found in every age group: children, adults and the aging, both male and female. There are still many oral health problems of Thai people in the northeast. KKU Field Works, Projects and Research were able to help reduce these oral health problems. An appropriate preventive oral health program needs to be developed and implemented in Northeastern Thailand.

As novel COVID-19 testing develops, saliva has become of increasing interest as an alternate biological sample for rapid testing. The appeal in saliva-based testing lies within the ease of which samples are collected, as well as patient comfort throughout the collection process. With this, it has become increasingly important to delineate the characteristics of saliva viscosity due to its effects on the movement and interactions of the substances and molecules found within it. The characteristics that affect saliva viscosity include the presence of aggregates, variations in temperature, and time elapsed between sample collection and testing. Understanding how physicochemical properties and temperature affect saliva’s viscosity are important in generating guidelines for proper sample handling in saliva testing to ensure consistent and reliable results. In this study, passive sampling of saliva was analyzed. This type of collection ensures a more uniform saliva composition, suggesting that variations in viscosity can be attributed solely to modifications in saliva handling post-collection. The data suggested that saliva viscosity is greatest immediately following collection of the saliva sample, increases with higher quantities of aggregates in saliva, and decreases tremendously when the sample has been frozen and thawed to room temperature. These findings suggest that to ensure accuracy and uniformity in quantitative saliva-based test results, protocols should favor the testing of a sample immediately following its collection. The implications of these results in optimizing saliva testing are far reaching. The value of saliva based testing extends far beyond COVID-19 or other disease testing. It is also gaining utility in understanding daily fluctuations in hydration state and in other wellness applications.
