Оценка времени, отведенного на физические упражнения, и привычек питания для группы подростков из технического колледжа

Universitatea de Medicină și Farmacie Grigore T. Popa, Iași, RomâniaCreșterea și dezvoltarea sunt două procese influențate de mai mulți factori interni și externi. În ceea ce privește factorii externi, timpul petrecut pentru efectuarea exercițiilor fi zice și dieta joacă un rol important. Studiul a fost realizat pe un eșantion de 184 de adolescenți de la Colegiul Tehnic din Bacău. În studiu au fost incluse 67 de fete (36,41%) și 117 băieți (63,58%). A fost măsurat timpul alocat exercițiilor fi zice și obiceiurilor alimentare. În majoritatea cazurilor (45,10%), timpul alocat exercițiilor a fost mai mic de 30 de minute. Diferențele de sex sunt semnificative din punct de vedere statistic la p<0,01 (ƒ=2, χ²=17,125) și se referă la fetele care acordă o atenție modestă activității fi zice. Consumul de lapte este de 1 dată pe săptămână (32,06%) sau de două ori pe săptămână (28,80%), consumul de ouă – de 2-3 ori pe săptămână, diferențele în funcție de sex fiind nesemnificative statistic. Cartofi i sunt prezenți în special în meniu – de 2-3 ori pe săptămână (38,04%), iar produsele pe bază de zahăr sunt consumate zilnic (38,04%). Diferențele calculate pentru ambele elemente sunt nesemnificative din punct de vedere statistic. Așadar, obiceiurile alimentare sunt similare între sexe, dar preocuparea pentru activitatea fi zică este diferită.Growth and development are two processes influenced by several internal and external factors. Concerning the external factors, the time spent exercising and diet, play a key role. The study was done on a sample of 184 adolescents from a Technical College in Bacau. There were 67 girls (36,41%) and 117 boys (63,58%). We measured the time allotted for physical exercise and their eating habits. In the majority of cases (45.10%) the exercise time was less than 30 minutes. Gender differences are statistically significant at p<0,01 (ѓ=2, χ²=17,125) and draw attention to the girls who pay modest attention to physical activity. Milk intake is 1 time per week (32,06%) or twice per week (28,80%), eggs 2-3 times per week, diff erences based on sex being statistically insignificant. Potatoes are especially present in the menu, 2-3 times per week (38,04%) and sugar products are present daily (38,04%). Differences calculated for both items are statistically insignificant. Eating habits are similar between the sexes, but the concern for physical activity is different.Рост и развитие – это два процесса, на которые влияют несколько внутренних и внешних факторов. Что касается внешних факторов, время, затраченное на физические упражнения, и прием пищи играют ключевую роль. Исследование было проведено на выборке из 184 подростков из технического колледжа в городе Бакэу. Группа состояла из 67 девочек (36,41%) и 117 мальчиков (63,58%). Было измерено время, отведенное на физические упражнения, и пищевые привычки. В большинстве случаев (45,10%) время тренировки составляло менее 30 минут. Гендерные различия статистически значимы при p<0,01 (ƒ=2, χ²=17,125) и указывают на то, что девушки уделяют меньше времени физической активности. Потребление молока составляло один раз в неделю (32,06%) или два раза в неделю (28,80%), яиц – 2-3 раза в неделю, различия по половому признаку статистически незначимы. Картофель присутствует в меню 2-3 раза в неделю у 38,04% опрошенных, а сахарные продукты присутствуют ежедневно у 38,04%. Различия, рассчитанные для обоих факторов, статистически незначимы. Пищевые привычки схожи между полами, но забота о физической активности разная

An Interdisciplinary Study Regarding the Characteristics of Dental Resins Used for Temporary Bridges

Background and Objectives: The surface condition of the materials that are used for temporary prostheses influences their microbial colonization, with a direct impact on the oral tissues. This study aims at a comparative analysis of three types of resins for temporary bridges using conventional and digital technologies. The attention was focused on the analysis of the surface characteristics and mechanical strength of these materials. Materials and Methods: The surface condition was assessed for three distinct materials both before and after polishing- heat-curing resin Superpont C + B (SpofaDental, Jicin, Czech Republic) used unconventional technology, Zotion dental milling polymethyl methacrylate (PMMA) block (Zotion, Chongqing, China) for provisional crowns/bridges used in digital subtractive technologies and Freeprint Temp (Detax GmbH & Co. KG, Ettlingen, Germany) resin for temporary crowns and bridges that are used in 3D printing technologies. The two-way ANOVA analysis indicated that polishing leads to a statistically significant increase in roughness coefficients for all the three resins that were tested (p Results: The results revealed that surface roughness was significantly influenced by both the type of resin that was used (p p p-values were obtained for each of the three resins. Conclusions: The results demonstrated a significant optimization of the surfaces after finishing and polishing and statistically significant differences between the surface parameters and the mechanical properties of the samples. The low values of the roughness and the acceptable values of the mechanical resistance for the conventional samples indicate these materials for the long-term temporary bridge’s realization, allowing the correct restoration of the functions and the rehabilitation at the oral level

Periodontal Disease Diagnosis in the Context of Oral Rehabilitation Approaches

Periodontal diseases generally correspond to a disturbance in the balance between the host’s defense and the micro-organisms colonizing the periodontal environment. The exact mechanisms underlying the destruction of the periodontium remain to be fully elucidated. Our study aims to quantify the main bacteria pool involved in periodontal pathology and associate it with other factors involved in the onset of periodontal disease so that an accurate diagnosis with profound implications for the therapeutic algorithm can be developed. Micro-Ident tests, based on the polymerase chain reaction (PCR) technique, were used for the study group, chosen for their high specificity in identifying periodontopathogenic bacteria and determining their relative numbers. The results of our study indicate an increased concentration of 4.50 (number of strains) for Capnocytophaga, followed by Tannerella forsythia, in a concentration of 3.50; the next highest concentration percentages are for Treponemei denticola, and Prevotela intermedia, low concentrations were found for Fusobacterium nucleatum and Porphyromonas. The concentration of each type of bacteria is reflected in the clinical picture and constitutes the starting point for a targeted antibiotic therapy. Following the effects of antibiotic-targeted therapy obtained from the evaluation of the micro-IDent B test results on the periodontium of the supporting teeth, we observed that the values of the periodontal indices change slightly at 3-month intervals with a predominance of plaque, bleeding, and gingival indices, and less in the indices concerning the depth of the probing pocket and the loss of attachment on the buccal and oral surfaces. In conclusion, our study emphasizes a direct relationship between the subgingival tartar presence and the patients age, gingival recession, presence of periodontal pockets, dental mobility, as well as the periodontal indexes: plaque index, bleeding index, and gingival index. The correlation of negative values of periodontal indices with the nature of the involved bacteria materializes in relevant starting points in the elaboration of the periodontal diagnosis of the therapeutic plan and predictability of the prognosis of oral rehabilitation
