INFLUENCE OF ENVIRONMENTAL FACTORS ON THE CONDITION OF ADOLESCENT DENTAL HARD TISSUES: CLINICAL AND PHYSICOCHEMICAL ANALYSES
Get PDFThe aim of the work was to investigate the peculiarities of the influence of environmental factors on the state of the dento-mandibular system in 15-year-old adolescents. Patients were examined in a dental chair using standard sets of examination instruments: mirror, forceps, and probe. Visual assessment of the state of oral organs and tissues was carried out using standardized indices. In male subjects, the index value of the calculated microbiological activity index living in Aidarken, Sumsar and Shakaftar were significantly worse compared to controls. The concentration of different minerals in saliva in this group was 1.5E-07±2E-08, which is an essential indicator to assess the mineral balance and remineralization potential of tooth enamel. The value of the lesion index ratio in this group was 4.211±0.397, which is a statistically significant deviation (p<0.005). This increase can be explained by the chemical influence on the population due to the activity of plastic factories, which negatively affects the oral health of adolescents and increases the risk of caries development. This result emphasizes the importance of considering environmental factors when assessing dental health in different regions. Importantly, significant differences were found between groups depending on the dominant unfavourable factor. This means that different environmental and chemical factors may have different effects on the caries-forming activity of dental plaque, which requires an individualized approach to caries prevention and treatment in different settings

Get PDFOil palm is a plantation commodity that plays an important role in advancing the country's economy. Jambi Province is one of the centers of oil palm plantations in Indonesia. dominated by smallholder plantations which are generally managed in an inaccurate way, causing Jambi Province's oil palm productivity (3,506 kg/ha) to be lower than the National productivity (3,873 kg/ha) and resulting in the expansion of the TTM/TR area. The purpose of this study was to study the effect of applying and obtaining the best dose of palm frond compost and NPKMg fertilizer on the growth of oil palm seedlings (Elaeis guineensis Jacq.). This research was conducted at the Teaching and Research Farm, Faculty of Agriculture, University of Jambi and lasted for months, starting from July-October 2022. This study used a Randomized Block Design (RBD) with 6 treatments, namely: p0 = 100% NPKMg (recommendation), p1 = 20% palm frond compost + 80% NPKMg (R), p2 = 40% palm frond compost + 60% NPKMg (R), p3 = 60% palm frond compost + 40% NPKMg (R), p4 = 80% palm frond compost + 20% NPKMg (R), p5 = 100% palm frond compost. Variables observed included height increase (cm), increase in tuber diameter (mm), increase in the number of leaves (strands), shoot dry weight (g), root dry weight (g) and root crown ratio. The results showed that the application of palm frond compost and NPKMg fertilizer was able to increase growth in the variable increase in weevil diameter and increase in the number of leaves. However, it has not been able to increase the increase in seedling height, shoot dry weight and root dry weight and obtain a good root canopy ratio. Dosage of 60% palm frond compost + 40% NPKMg gave the best average growth of 6 months old oil palm seedlings in the main nursery. In addition, applying palm frond compost can reduce the use of NPKMg fertilizer by 60% or 30 g/seed.
