Objectives: COVID-19 has caused a negative impact and paralysis in the activities of the dentistry field because it has a high risk of contamination and transmission of the SARS-Cov-2. Even so, dental services cannot stop completely, especially for emergency cases, so that a new form of adaptation of normality is recommended for all dental services including the dentomaxillofacial radiology. This article aims to discuss the adaptation to the new normal era of in the dentomaxillofacial radiology examinations. Literature Review: The use of dentomaxillofacial radiographic examinations is indispensable for diagnosis and determination of treatment plans, but in the era of the COVID-19 pandemic and this new normal era, modifications are needed in stricter infection control in dentomaxillofacial R\radiology installations to prevent as much as possible the possibility of virus transmission SARS-Cov-2. The application of room controls, medical personnel, x-ray equipment, patients, and radiograph documents are very important in carrying out the adaptation to this new normal era. Conclusion: An adequate infection control and application of teleradiology are important things to be considered and implemented as a form of adaptation to new normal in dentomaxillofacial radiology installations in patient care as a way to prevent transmission and contamination of the SARS-Cov-2 virus during the COVID-19 pandemic.

Background: Radiography is the most frequently used supporting examinations in the medical field, especially in dentistry. The use of radiography is important for establishing a diagnosis and further treatment. This radiographic imaging technique can produces radiation that can cause both ionizing and non-ionizing effects. Ionizing effects are divided into two, stochastic effects and deterministic effects, these effects can cause biological damage. These effects need to be known pre-clinical and clinical students as an act to prevention. Objective: To compare the level of knowledge of pre-clinical and clinical students regarding the dangers of radiation exposure at RSGM-P Universitas Trisakti. Methods: Respondents in this study were 100 pre-clinical and clinical students consisting of 50 pre-clinical students who had taken module 412 (Supporting Examination for Diagnostics) and 50 clinical students at RSGM-P Universitas Trisakti using a questionnaire by distributing via the google link forms. Results: The Mann-Whitney test showed a significant difference in knowledge of the dangers of radiation exposure between pre-clinical students 45.3% and the clinic students 54.7%. Conclusion: There is a difference in the level of knowledge between pre-clinical and clinical students at RSGM-P Universitas Trisakti regarding the dangers of radiation exposure.

Objectives: This research is aimed to determine the wide frequency distribution of anteroposterior frontal sinus with lateral cephalometric radiographs based on age and sex in West Jakarta, which is centered on RSGM FKG Trisakti University.   Material and Methods: This research is using descriptive observational research design and the anteroposterior width measurement of the frontal sinus uses the Erturk measurement method. This study used 125 lateral cephalometric radiographs (40 males and 85 females) as samples which taken from a server at the Dental Radiology Installation, RSGM FKG Trisakti University. Results: The result showed that the smallest mean width of the anteroposterior frontal sinuses in males is at 7 years (5.4 mm) and the largest size is at 19 years (9.76 mm). Whereas the smallest mean width of anteroposterior frontal sinuses in females is at the age of 7 years (5.4 mm) and the largest size is at the age of 20 years (9.25 mm). The average width of anteroposterior frontal sinuses is 6.6 mm in males and 5.58 mm in females. Conclusion: Males have an average width of anteroposterior frontal sinuses that is larger than females and there are some decrease in size in some age groups. Variations in size can occur due to genetic and environmental factors.

Introduction: a preoperative assessment of bone density plays a vital role in the success of dental implant treatment. the maxilla and mandibular alveolar bone had a variety of bone densities. Therefore, dental imaging is an important step before placing a dental implant. Recently, Cone beam computed tomography (CBCT) is widely used in dental medicine and also recommended by AAOMR for preoperative implant placement. The aims of this study is to analyzed the alveolar bone density of the dental implant sites for dental implant planning using CBCT. Methods: ninety-three CBCT data were retrieved from the database of the department of oral and maxillofacial radiology at Dental Hospital Faculty of Dentistry Universitas Trisakti and examined. The recipient sites for dental implant placement were determined based on CBCT data using implant planning software (i-Dixel). The alveolar bones value is recorded in grayscale value (GV). Results: a great variety of alveolar bone density was observed ranging from 134-891 GV. One-way ANOVA was conducted, and statistically significant was only shown at the anterior mandibular region and molar mandibular region. However, no statistical differences were observed when comparing the male and female groups using the T-test. Conclusion: Critical evaluation through dental CBCT can be made before dental implant placement in the alveolar bones. the lowest alveolar bone density was observed in maxillary molar dental implant sites with mean 322 GV and highest alveolar bone density was shown in mandibular anterior dental implant sites with mean 558.8 GV. Determining the bone density at the dental implant site before dental implant placement is crucial. Primary stability and secondary stability is determined by bone density. Therefore, higher value of alveolar bone density is needed for dental implant placement.  Keywords: alveolar bone density assessment; dental implant; cone-beam computed tomography.
