Abstract: Objective: Dental offices, due to the special characteristics of diagnostic and treatment operations and airborne diseases, are exposed to relatively closed environments with high concentrations of aerosols for a long period of time, and there is a possibility of disease transmission through aerosols. This paper introduces and analyzes the sources, distribution, hazards, and prevention and control strategies of oral bioaerosols, hoping to provide some references for reducing the hazards of oral aerosols and optimizing errors and omissions in dental treatment. Materials and Methods: By reviewing and summarizing the way of generating oral aerosols, the factors affecting their distribution in the past two decades, and reviewing the related literature, we explored the hazards of oral aerosols to the organism and the reasonable preventive and control measures. Results: Aerosol in dental clinic can spread through many forms, such as saliva of patients, water vapor splashing from dental high-speed mobile phone operation, etc., which increases the risk of infection between doctors and patients. Conclusion: A large amount of aerosols will be generated in the process of oral diagnosis and treatment, and the pathogens contaminating the air can directly lead to respiratory tract infections, and can also indirectly infect human beings through contaminated medical devices. The risk of aerosol transmission can be reduced through good scientific protection, standardized operation, rinsing and disinfection, and the use of isolation and strong suction equipment.

Abstract: Commiphora myrrha, is an ancient plant which exhibits an antiseptic and anti-inflammatory effect for mouth and it has been traditionally used for its antimicrobial properties in oral health care. This study assessed the impact of C. myrrha on two bacteria Streptococcus mutans and Lactobacillus spp. involved in dental caries. Three samples of Streptococcus mutans bacteria were collected randomly from patients with dental caries in Khartoum dental teaching hospital, while Lactobacillus spp. isolates were obtained from fermented milk. Disc and well diffusion methods were used to test the effect of four concentrations (100, 50, 25 and 12.5 mg/ml) of Myrrh volatile oil, extracted by hydro-distillation technique. Ampicillin, Vancomycin and Ciprofloxacin were used as control positive. The phytochemical analysis of C. myrrha oil was carried out using Gas Chromatography Mass Spectroscopy technique. The finding of this study revealed that the four concentrations of essential oil were effective on S. mutans with the largest inhibition zone (18.7± 0.6 mm) through the well diffusion method and inhibition zone of 14.00 mm with disc diffusion method, regardless the two methods; the inhibition zones were recorded at 100 mg/ml, with Minimum Bactericidal Concentration (MBC) at 3.125 mg/ml. On the other hand, Lactobacillus spp. bacteria was found to be sensitive to three concentrations of oil (100, 50 and 25 mg/ml) and resistance to lowest concentration (12.5 mg/ml), the MBC found to be 25 mg/ml. The results of GC-MS revealed the presence of 48 compounds, the highest percentage were; Benzofuran (29.13%) followed by Cyclohexane (19.88%) and 1,3-Diphenyle-1,2-butanediol (15.17%) respectively. Myrrh oil is effective on both S. mutans and Lactobacillus spp. Hence, it is a potential antibacterial product of interest in dental caries.

Abstract: Background: In the process of dental diagnosis and treatment, a large number of pathogenic microorganisms and aerosols in the mouth of patients are easy to spread into the office, resulting in microbial contamination of the office air. In order to reduce the formation of droplets and aerosols and reduce the dissemination of blood and saliva, negative pressure suction is usually used to reduce most of the aerosols. Objective: In order to reduce the formation of droplets and aerosols and the dissemination of blood and saliva, a branch saliva suction device with both strong and weak suction functions is needed. Methods: A branch saliva suction device with both strong and weak suction functions was designed. Including grip, extension rod, bending pipe, strong straw, pressure sensor, hard pipe, weak straw, sliding block. By inserting a weak straw at the outside of the extension rod, and setting a strong straw at the end of the extension rod, the strong straw and weak straw are combined, so as to improve the applicability of the device and facilitate the user to operate with one hand. By setting a sliding block on the outside of the extension rod, the sliding block can be connected with the outside of the weak straw, and the length of the weak straw can be freely adjusted according to the need, which is convenient to adjust the weak straw, and at the same time, the weak straw can be collected. Results: A branch oral salivary suction device was designed to improve the efficiency of diagnosis and treatment and the comfort of patients. Conclusion: To design a branch saliva suction device for oral use.

Abstract: Background: As the needle is a sharp instrument, it can easily injure soft tissue, a syringe without a needle is generally used for drug injection in clinical practice, and the liquid in the syringe is poured into the periodontal pocket under the guidance of probe. However, there is a problem that the liquid cannot be accurately delivered to the periodontal pocket for spot injection, resulting in poor therapeutic effect. Objective: To explore a kind of periodontal probe can detect the depth of the periodontal pocket and also can locate the injection liquid. Method: Through the literature review, a periodontal probe for positioning injection was proposed to accurately detect the periodontal pocket depth and accurately release the medicine in the periodontal pocket. So that students can understand the knowledge of traditional Chinese medicine and oral cavity and familiar with a series of processes of invention patents. Enable students to participate in the whole cycle of personnel training process. Result: A device was successfully designed. It can not only export the drug liquid by using the pressure liquid guide mechanism with repeated piston movement, but also locate the position of the drug on through the spherical probe of the probe to achieve accurate drug delivery. It can also prevent soft tissue damage and improve the safety. Conclusion: A localized injection of periodontal probe is introduced to solve the problem that the traditional periodontal probe type may affect the accuracy of probing and have a certain impact on the patient's comfort, and to improve the direction of accurate drug delivery during detection. It also stimulate the students' enthusiasm for learning.
