This paper investigates the current situation of digital education in 94 undergraduate universities and junior colleges of Stomatology in China through electronic questionnaire and telephone interview. It shows that digital Stomatology education in China has developed rapidly in recent years. Most colleges have been gradually applying digital teaching methods, and some colleges have carried out teaching on digital oral diagnosis and treatment technology. However, the development of digital Stomatology education in China is still inadequate. There are still problems such as insufficient understanding of its importance, personnel training failing to meet the application needs, and lack of digital education courses. In response to these problems, some suggestions on accelerating the development of digital Stomatology education in China are put forward in this paper.

The treatment of head and neck cancer is dominated by surgery and radiochemotherapy. For elderly patients, however, the rationality of invasive treatment is questioned in clinical practice. Although the proportion of geriatric patients with head and neck cancer is increasing, there are few consistent standards in the literature and guidelines. From the perspective of evidence-based medicine, this paper presents current evidence for treatment so as to provide specific recommendations for treating head and neck cancer in the elderly. Furthermore, based on a systematic literature review, a clinical algorithm is proposed to evaluate the treatment risk of elderly patients with head and neck cancer.

Mouth breathing in children not only affects the growth and development of teeth and maxillofacial, but also may seriously affect the physical and mental health of children with sleep disordered breathing. Mouth breathing can be divided into obstructive mouth breathing and habitual mouth breathing. Its occurrence and development may be related to various systemic diseases such as allergy, inflammation, immunity, genetics, etc. It also involves changes in the structure of the oral temporomandibular joint, perioral muscle group, dental arch morphology, and development of the upper and lower jaws. Therefore, the treatment of mouth breathing in children should be a multidisciplinary combined sequential treatment plan based on the causes associated with different organs or systems. From the perspective of orthodontists, this paper analyzes the diagnosis and treatment process of different types of mouth breathing, so as to provide reference for clinicians.

The increasing incidence of peripheral nerve injuries brought on by trauma or tumors is substantially interfering with people's lives due to the causal sensory and motor dysfunctions. Peripheral nerves have some self-repair ability after injury, but they are limited by the degree of injury and the body's condition. The postoperative recovery of nerve function in patients is not satisfactory, which is closely related to the local inflammatory microenvironment after injury. Melatonin, a compound naturally synthesized in the pineal gland, protects peripheral nervous system cells from oxidative inflammation after injury and regulates their behavior and fate.Therefore, it has good application prospect in nerve tissue engineering. In this paper, we review the synthesis, metabolic processes underlying melatonin, mechanism of action as well as the current status of its application in peripheral nerve regeneration as well as potential application for oral diseases. In this way, it further provides a new idea for the clinical treatment of peripheral nerve injury.

The lip plays a crucial role in facial aesthetics, making them a focal point of interest for orthodontists and patients throughout orthodontic treatment due to their three-dimensional changes in morphology and position. The degree of improvement in lip morphology significantly impacts post-treatment satisfaction among orthodontic patients. Therefore, understanding the influencing factors of lip morphology and its correlation with orthodontic interventions enables orthodontists to predict post-treatment changes in lip morphology more accurately, facilitating the customization of orthodontic treatment plans. In this paper, we reviewed the progress of methods for evaluating lip morphology and its influencing factors in order to provide reference for clinical practice.

Bitter taste in the mouth is a prevalent clinical symptom that refers to a spontaneous bitterness in the mouth after excluding external factors such as diet, and belongs to the phantogeusia of dysgeusia. The etiology and mechanism of bitter taste in the mouth remain unclear. Studies have shown that bitter taste in the mouth is mainly associated with multiple factors such as diseases, medications and nutrition. In addition, effective and reliable treatments have also not yet been developed. This paper reviews the latest research advances in the etiology, mechanism and treatment of bitter taste in the mouth, with the aim of providing reference for the clinical management of patients with mouth bitterness.

Removable partial denture is one of the most important means of treating dental defects for its high strength, low price, wide range of indications, minimal trauma and repairability. With the aging of the population becoming more and more prominent, removable partial dentures will continue to be a common restorative method in the future. The production of removable partial denture cannot be separated from the accurate impression technology, and there are many shortcomings in the process of taking impressions of traditional removable partial denture, such as the number of visits, time-consuming, complex production process, high pollution, waste, low efficiency, and the quality is not easy to control, etc. However, the emergence of digital impression provides new technical support for the taking of removable partial denture impression. Digital impression technology has the advantages of high precision, comfort, high efficiency, shortened treatment time and personalized design, which helps to improve the effect of removable partial denture restoration and patient satisfaction. As the premise and foundation of the whole digital removable partial denture restoration treatment, accuracy of the reconstruction of the oral model directly affects the final denture restoration effect. At present, digital impression technology has been widely used in the field of oral restoration. This paper will review the current status of the application of digital impression technology in removable partial denture, in order to further guide the clinical application.

As an important branch of artificial intelligence, machine learning meets the demand for digital intelligence in prosthodontics with the rapid development and application of its algorithm. This review provides an overview of the application of machine learning algorithms in dental restoration, including the design of dental prostheses, tooth shade selection, and tooth preparation line detection. Additionally, this paper also briefly analyzes the merits of machine learning and discusses the challenges and issues in current research, to provide references for research on machine learning algorithms in prosthodontics.
