Background: Panoramic and cephalometric radiography is very important for diagnosis, treatment plan, and evaluation of orthodontic treatment results. Panoramic and cephalometric radiography are frequently performed at the same time, causing DNA damage and chromosome aberration. Purpose: This study aims to analyse the effect of X-ray exposure in panoramic and cephalometric radiography on micronuclei cell numbers. Methods: Laboratory-based analytical study with 60 healthy-male Wistar rats weighing 200–300 grams divided into 6 treatment groups (n=10). The control group: without radiographic exposure, the treatment group 2: using panoramic radiographic exposure followed by cephalometric, and the treatment group 3: using panoramic radiographic exposure and 24 hours later performed cephalometric radiographic. The unit of analysis was the polychromatic erythrocytes of mice cell, were examined 24 hours and 48 hours after irradiation had been finished. The polychromatic erythrocytes were examined using May-Gruenwald-Giemsa staining and 100x magnification under a microscope with 2000 cells per view. Data obtained were analysed using the SPSS 20 version software. The mean and standard deviations were calculated for each clinical parameter, and a one‐way ANOVA statistical test of significance was used. Statistical significance was set at p<0.05. Results: The analysis showed a significant increase (p<0.05) in the number of micronucleus in groups that used panoramic radiographic exposure followed by cephalometric. Conclusion: X-ray radiation can increase the number of micronucleus in polychromatic erythrocyte cells in rats.

Objectives: The principle of measurement using the TCI (Tooth Coronal Index) method is to compare the pulp chamber height with a person's chronological age based on the formation of secondary dentin. The purpose of this study is to estimate age based on pulp chamber height in lower canines using periapical radiographs with TCI measurement. Materials and Methods: This study is an observational analytic study using 42 samples of periapical radiographs with the parallel technique of the lower canines. Samples were measured for CH and CPCH heights to determine TCI values and then linear regression was made to determine their biological age. Finally, the difference between biological and chronological age is calculated to determine the approximate age. Results: The mean difference between chronological age and biological age was ± 5.05 years and an average biological age of 29.38 years. Conclusion: TCI method based on pulp chamber height in lower canines using periapical radiographs can be used to estimate age with the difference between chronological age and biological age of ±5.05 years.

Radiation is any kind of energy transmitted without an intermediate medium. Radiant energy is generally wave-shaped, most commonly sinusoidal. There are two types of radiation: ionizing radiation and non-ionizing radiation. Ionizing radiation is radiation that causes the process of ejecting electrons from atoms to form ion pairs. Attention should be paid to ionizing radiation, particularly its sources, types, properties, effects, and methods of avoidance. Ionizing radiation is well known, for example radiation from X-rays. Non-ionizing radiation can occur in equipment and mobile phones. Miftaful Ulm Merilan Madrasah Tsanawaya School is in Merilan Village, Bunga District, Eastern Gresik Regency. The location of this school is far from the city center. Student health contributes to the smooth running of the educational process. There is a lack of knowledge and awareness among students and residents in Bunga district that radiation hazards affect their quality of life. A technical implementation of this training will help you address the material. Students were assessed using pretests and posttests. The mean score before the pretest was 32.7, and after listening to the material and after the posttest was 80.

Noni fruit (M. citrifolia L.) is a medicinal plant known for its antioxidant bioactive compounds, which have potential use as radiation protection agents. Despite their traditional use, the specific bioactive compounds and their efficacy as radiation protectants have not been thoroughly investigated. This study aims to address this research gap by evaluating the potential of noni fruit extract as a candidate for radiation protection using in-silico methods. Databases consulted include PubChem, PASS Online, and ProTox-II. The results identified nine bioactive compounds in noni fruit extract: quercetin, kaempferol, morindin, morindone, alizarin, nicotinamide, beta-sitosterol, squalene, and n-hexadecanoic acid. Among these, kaempferol, squalene, and n-hexadecanoic acid were found to be the most potent antioxidants. Kaempferol exhibited a low toxicity level (grade 5) with significant activity as an antioxidant (Pa ≥ 0.7), free radical scavenger (Pa ≥ 0.7), and radioprotector (Pa 0.3 – 0.7). Squalene, a triterpene with low toxicity (class 5), showed antioxidant activity (Pa 0.3 – 0.7), free radical scavenger activity (Pa 0.3 – 0.7), and radioprotection (Pa 0.3 – 0.7). n-Hexadecanoic acid, a metabolite with moderate toxicity (class 4), demonstrated lower antioxidant activity (Pa ≤ 0.3), while morindin exhibited free radical scavenging and radioprotective properties. The findings suggest that kaempferol, squalene, and n-hexadecanoic acid in noni fruit extract hold promise as candidates for radiation protection, as evidenced by in-silico analysis.

Produced by a stingless bee (Tetragonula biroi) from Sulawesi Island, propolis is an active compound that requires further studies to determine its herbal-based medicinal applications. In addition, propolis is well known as a potential natural ingredient for herbal medicine with minimal side effects. The stingless honeybee, native to Sulawesi, produces propolis, a resin. Propolis from Trigona stingless bees in Sulawesi has the highest flavonoid content compared to Apis mellifera bees. Flavonoids are the most common compounds contained in propolis. Propolis from stingless bees may have the potential to stimulate osteoblast cell proliferation and be responsible for bone regeneration. The objective of this study is to investigate the viability of the 7F2 pre-osteoblast cell line after administration of the stingless bee’s 1% propolis nanoemulsion extract (PNE). A 1% PNE was formulated by maceration methods and diluted into several concentrations of 100%, 50%, 25%, 12.5%, 6.25%, 3.125%, 1.56%, and 0.78%. A particle size analysis was done to examine the particle size and zeta potential of the 1% PNE. A Tetrazolium Technique assay was carried out to examine 1% PNE application on a 7F2 pre-osteoblast cell line on days 1, 3, and 7. The highest viability of 7F2 pre-osteoblast cells was at 0.78% concentration on day 7, and the lowest viability was observed at 100% concentration on day 1, with significant differences among groups (p < 0.05). A 1% PNE with a particle size of 151.28 to 182.2 nm and a zeta potential of −32.76 mV was successfully formulated. The 1% PNE was non-toxic to 7F2 pre-osteoblast cells, with a cell toxicity limit at a concentration of 1.56%.
