Objectives: Dense Bone Island (DBI) is one of the lesions that are usually visualized on a panoramic radiographs in the form of total radiopaque in the periapical area of the mandibular premolar or molar but most of them are not directly related to the dentition. This case report is aimed to give summaries about the description of 3 DBI cases. Case Report: Three panoramic radiographs of patients with asymptomatic well-defined radiopaque lesions which was found incidentally in the periapical area of the left mandibular first premolar with two of them showing the lesions located exactly in the 1/3 apical of the root and one of them seen as root resorption like. From clinical information, all three cases reported no clinical symptoms and affected teeth are still vital. Conclusion: Incidental findings of well-defined radiopaque lesion in the periapical area of the premolar and molar of mandible that mostly do not damage the surrounding teeth lead to the diagnosis of dense bone island.

Objectives: The purpose of writing this literature review is to describe the condyle shape and position parameters in panoramic radiographs to be used as markers in diagnosing a TMD case. Literature Review: There are several classifications of both normal and pathological condyles in terms of panoramic radiographs, however these require more detailed observation. Panoramic radiographs that are only two-dimentional and only performed when the teeth are biting edge to edge so that they only show the position of the condyle movement and the shape of the condyle from the lateral view. Panoramic radiograph also have limitations in imaging soft tissues such as articular disc which are vital anatomy in analyzing a TMD case. Conclusion: Assessment of the shape and position of the condyles on a panoramic radiograph can be used as an early diagnosis of TMD. 2-dimensional modalities such as TMJ conventional lateral and frontal or 3-dimensional modalities such as CBCT or CT can be used for further assessment of a TMD case, while MRI or ultrasound can be used for soft tissue abnormalities.

Objectives: This article is aimed to widely share information and discuss further about the emerging transformation theories of the traditional radiation protection concept of ALARA into some more modern proposed concepts, particularly in dentomaxillofacial radiology. Literature Review: The concept of radiation protection in the use of X-ray modalities in the medical field has developed along with the development of science over past decades. The concept of ALARA which has been widely known for a long time and is used as a basic of theory or main reference in radiation protection policies in several countries or at the international level now becomes a traditional, conservative and invalid principle to apply. There are several emerging theories which are considered to be more valid and representative to replace the ALARA principle. Conclusion: Newer concepts of radiation protection that have developed, ALADAIP, are considered to be more precise and specific to be the main principle of radiation protection at this time, especially in the field of dentomaxillofacial radiology.

Objectives: The most commonly encountered impacted tooth is the third molar, and potential problems include oral cysts and tumors as well as caries, periapical lesions, periodontal disease, TMJ disorders, and root resorption of adjacent teeth. The aim of this investigation was to determine the third molar impaction prevalence and pattern. Materials and Methods: 530 panoramic radiographs of patients who visited Hasanuddin University Dental Hospital from January to December 2020 were collected. Data were recorded based on third molars region, eruption level, angulation, and impaction class from radiographs that met the criteria on Excel sheets and analyzed using SPSS 26. Chi square test was performed to assess relationship between impaction patterns with age and gender. The level of significance was fixed at p<0.05. Results: 115 radiographs were included and analyzed (45.2% male and 54.8% female). Third molar impaction prevalence was higher in females, in the age group 21-30 years, with level A eruption and vertical angulation. Most #38 and #48 demonstrated class 2 impaction. Apart from angulation and impaction class on #38, there was no significant difference between impaction patterns by age and gender group (p>0.05). Conclusion: Third molar impaction was more common in women aged 21-30 years with a dominant impaction pattern at level A with vertical angulation. In the mandible, class 2 of the Pell and Gregory classification are known to be dominant in third molar impaction.

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.
