Radiation can originate from various natural and artificial sources. Ionizing radiation can impact individual health because ionization events can result in DNA damage, cell death, and harm to tissues and organs. The elderly is one of the vulnerable groups that should receive more attention regarding their health conditions. Aging is a natural phase in the human life cycle that significantly affects various aspects of life, including health and quality of life. The quality of life in the elderly can be influenced by their well-being, emotions, physical health, occupation, cognitive abilities, and social life. In connection with the radiation phenomenon that can have serious implications for the health and quality of life of individuals, including the more vulnerable elderly population, adequate knowledge about safe radiation utilization and a detailed understanding of radiation's effects and prevention become essential in maintaining their health and improving their quality of life. Community outreach activities were conducted in the form of educational seminars with the aim of increasing the elderly community's literacy regarding the effects and utilization of radiation in the Trawas District, Mojokerto Regency, over a duration of one day. It is worth noting that the Trawas District, Mojokerto Regency, has experienced an increase in its elderly population over the past few years. The results of this community outreach program have shown a positive overall progress, with an increase in participants' self-confidence in understanding the provided material and an improvement in their knowledge regarding the utilization and prevention of radiation effects. This improvement is demonstrated by the significant difference between pre-test scores (mean value: 22.82) and post-test scores (mean value: 80.82), as assessed through a statistically significant paired T-test (t value: 35,537 with p<0.001) and Wilcoxon signed-rank test (p<0.001).

Background: The parallel technique stands as a prominent method for radiographic examinations aiming to identify furcation involvement. Nevertheless, an inherent limitation lies in the frequent superimposition of the trifurcation region with tooth roots, potentially leading to inaccurate diagnoses. The Same Lingual Opposite Buccal (SLOB) technique was devised to yield radiographic images that alleviate superimposition at the trifurcation of the maxillary first molar. Purpose: to observe and compare the radiographic images of the trifurcation region of the maxillary first molar generated through the SLOB technique with the film holder modification set at a mesial and distal angulation of 20Ëš with the parallel technique. Methods: This observational analytic research encompassed a sample size of 24 instances. Each individual sample underwent three separate exposures: the SLOB technique with a horizontal angulation of 20Ëš towards both mesial and distal directions, and the parallel technique (serving as the control). Results: a significant difference in radiographic images of the trifurcation region of the maxillary first molar obtained through the SLOB technique, employing the film holder modification with a mesial angulation of 20Ëš and a distal angulation of 20Ëš, as opposed to the parallel technique (control). Conclusion: A radiographic image capturing the trifurcation of the maxillary first molar, devoid of superimposition, was successfully generated through the SLOB technique incorporating a horizontal angulation of 20Ëš towards the distal direction.

Background: Misdiagnosis can occur due to various radiographic alterations linked to odontogenic myxoma (OM). Regular examination can detect abnormalities early on, but not all practitioners are aware that these lesions exist. Purpose: This case report aims to describe and discuss an OM case from the perspective of oral radiology on panoramic radiographs and cone-beam computed tomography (CBCT). Case: A 23-year-old female went to her first dentist for orthodontic treatment with no prior radiographic evaluation. On January 7th, 2022, the second dentist extracted teeth 38 and 48 using the panoramic radiograph without identifying lesions. Concerned about swelling on her lower right gingiva, which had gradually grown, the patient went to an oral and maxillofacial surgeon on November 15th, 2022. The clinical examination revealed facial asymmetry with a thick, palpable, firm mass with an ambiguous boundary. Despite the evident movement of tooth 47, the gingiva exhibited no noticeable change in coloration. Case management: From the panoramic examination, multilocular radiolucency with radiopaque septa and aggressive mass characteristics were found. Advanced imaging CBCT was used to investigate further and correlate histology findings for treatment. Conclusion: Odontogenic myxoma is difficult to distinguish from other benign and malignant neoplasms due to the wide variations of radiological patterns. Cone-beam computed tomography provides a thorough and broad range of data that can be used to make a precise diagnosis and develop an effective treatment strategy. This highlights the critical need for a trained expert to thoroughly examine CBCT scans.

An automatic system for determining mandibular landmark points on panoramic radiography can reduce errors due to differences in expert professionalism and save time. Previous research has shown that the linear regression method is ineffective at predicting condyle and gonion landmark points in panoramic radiography. So, this research proposes an analysis of nonlinear regression methods (support vector machine (SVM) kernel=‘polynomial’, polynomial regression, ensemble regression) for predicting condyle and gonion landmark points. There are four predicted landmark points, namely the right condyle, left condyle, right gonion, and left gonion. The nonlinear regression methods used are SVM, polynomial regression, and ensemble regression. The Dental and Oral Hospital, within the Faculty of Dentistry at Universitas Airlangga, provides the research data. The research encompasses 119 patients between the ages of 19 and 70, dividing 103 into training and 16 into testing. The research results show that the SVM method is only good at predicting the right condyle point with a mean radial error (MRE) of 4,724 pixels. Meanwhile, to predict the left condyle, right gonion, and left gonion points, it is better to use the polynomial regression method and ensemble regression with an order of success detection rate (SDR) of 37.5%, 18.75%, and 12.5%, respectively.

The professionalism of the radiologist greatly influences the results of radiological images. The quality of panoramic radiography greatly influences accurate clinical diagnosis. The correct patient position is one of the many factors that affect high-quality and accurate panoramic radiography. The process of taking radiographic images causes radiation exposure to the patient, so that when taking radiographic images repeatedly it is very bad for the patient. A review research is needed to reduce radiation exposure by improving the quality of panoramic radiography. This research conducted a literature review by proposing the questions (1) What types of position errors in panoramic radiography have been researched? (2) How is the process of identifying position errors in panoramic radiography that have been researched? The results of the review research showed that the types of position errors in panoramic radiography that have been researched are the head turning, the tongue not sticking to the palate, the chin down, the chin not resting on the support. The process of evaluating position errors in panoramic radiography is mostly done manually, there is only one research that identifies position errors in panoramic radiography automatically using SVM. That there is a great opportunity to create an automatic system for identifying position errors in panoramic radiography to be more precise and time efficient.

AbstractA common side effect of radiotherapy used in the treatment of head and neck cancers is the occurrence of structural and physiological alteration of the salivary gland due to exposure to ionizing irradiation, as demonstrated by conditions such as decreased salivary flow. Ionizing irradiation cause burst of reactive oxygen species (ROS) such as superoxide, hydroxil and hidrogen peroxide which induce activation of self-defense system such as superoxide dismutase and catalase. If this defense system could not diminish the excessive amount of ROS it would lead to oxidative stress which can be determined by rise of malondialdehide (MDA) levels. The aim of this research is to find out the influence of single and fractionated dose of gamma ray irradiation on superoxide dismutase and catalase activities and malondialdehide levels in rat submandibular glands at 24 hours, 3 weeks and 6 weeks after exposure of gamma ray irradiation. For this research, experimental laboratory was done. Sixty male Wistar rats aged 3-4 months (250-300 g) grouped into three. Group A (20 rats) as control group were not irradiated. Group B (20 rats) were irradiated with single dose (10 Gy) and group C were irradiated with fractionated dose (10 Gy in 5 fraction of 2 Gy/day) of Co60 Gamma ray, with their neck ventral surface exposed to the source. The rat submandibular glands were extirpated at 24 hours, 3 weeks and 6 weeks after irradiation and then analysed for superoxide dismutase and catalase activities using microreader and malondialdehide levels using spectrophotometer. There were significant differences (p:0,000) of superoxide dismutase and catalase activities and malondialdehide levels after gamma ray irradiation at evaluation time 24 hours, 3 weeks and 6 weeks. Superoxide dismutase activity in group B (10 Gy single dose irradiation) and group C (10 Gy fractionated dose irradiation) decreased in compare to group A (control). Catalase activity in group B decreased in compare to group A at 24 hours, in group C catalase activity increased in compare to group A. Malondialdehide levels increased in group B and C compare to group A at 24 hours, 3 weeks and 6 weeks after irradiation.
