Systemic Inflammatory Response Syndrome and Serum Procalcitonin in Odontogenic Maxillofacial Infection

INTRODUCTION: The systemic inflammatory response syndrome (SIRS) is a progressive, pathophysiological process which may be caused by a variety of clinical precursor events including local or generalized infection, or non-infective inflammatory process.
 АIM: To determine the development of systemic inflammatory response syndrome (SIRS) and serum procalcitonin level in patients with odontogenic infection of the maxillofacial area.
 MATERIALS AND METHODS: The prospective observational study evaluated on 158 medical patients from 2015 to 2018 at the Department of maxillofacial surgery, Faculty of Stomatology, Vitebsk state medical University. The patients were divided into 3 groups: 1 group (96 people) had acute purulent odontogenic osteomyelitis of mandible complicated by the cellulitis of one space cellular spaces, group 2 (36 patients) had acute purulent odontogenic osteomyelitis of mandible complicated by the cellulitis of 24 cellular spaces, group 3 (26 people) had acute purulent odontogenic osteomyelitis of the mandible complicated by Ludwig's angina. Blood tests of all patients were performed. Based on the blood test, breath rate, heart rate and body temperature SIRS was determined.
 RESULTS: Acute odontogenic osteomyelitis, complicated by cellulitis, is characterized by the development of SIRS. In case of one cellular space cellulitis SIRS developed in 9.0% of patients, in case of 24 cellular spaces cellulitis in 36.0%, in case of Ludwig's angina in 80.0%. PCT blood level in healthy group was 0.009 (0.0060.018) pg/ml. All patients groups had significantly higher PCT blood level compared with the healthy group: 1 group 0.034 (0.0190.050) pg/ml, U = 23, р = 0.01; 2 group 0.11 (0.060.24) pg/ml, U =12, р = 0.003; 3 group 0.41 (0.301.15) pg/ml, U = 17, р 0.001.
 CONCLUSION: Odontogenic maxillofacial infection is accompanied by SIRS. The search for significant diagnostic criteria for the development of life-threatening conditions should continue.

USE OF ENGLISH SPECIFIC INFORMATION SOURCES IN EDUCATIONAL PROCESS AS A CONDITION FOR IMPROVING OF FUTURE DENTISTS’ PROFESSIONAL COMPETENCE

The need for close cooperation between different countries grows every year and necessitates the training of specialists who are fluent in languages of international communication, primarily in English, and use them in their professional activities. Today, it is difficult to imagine a competitive medical specialist who does not use knowledge of the English language in his/her activity to effectively establish professional contacts and obtain the latest information.
 The purpose of the article is to determine the possibilities of improving the quality of professional training of future dentists due to the improvement of foreign language communicative competence through the use of English-language professional information sources in educational process at clinical departments.
 Materials and methods. A search and study of publications on the specified issue was conducted in library sources and search engines.
 Research results. The change in requirements for modern student of higher medical educational institution, caused by the need to enter the world and European educational and scientific space, makes it necessary for future doctors to master the English language at a professional level. Proficiency in English gives future dentists direct access to professional literature, periodicals, websites, etc. Having a sufficient level of language skills, they will be able to expand their horizons of professional growth by attending international conferences, seminars, trainings, exhibitions, getting acquainted with the experience of leading scientists and practitioners.
 Based on this, it should be noted that turning to English-language professional sources in the training of future dentists should not be limited by professional English classes, but their use should become a necessary element of educational process at clinical departments. At the departments of Poltava State Medical University’s Stomatological Faculty the practice of including English-language publications in the lists of recommended literature, listening to reports at practical classes, and the results of individual tasks prepared in English based on the study of original scientific literature has already become a common practice. Nevertheless, the educational process at clinical departments needs more active implementation of such types of educational activities as finding and analyzing new textual, graphic and video information contained in professional materials in English. The work of student scientific groups should provide especially wide opportunities for this.
 Thus, it can be concluded that the use of the English-language professional literature, publications in periodicals, and Internet resources in educational process of future dentists should become an additional factor in students’ effective acquisition and assimilation of knowledge needed in future professional activities.

Formation of professor Mao Xiejun's thoughts on stomatological education

Professor Mao Xiejun wrote a report about dental education of China in 1935. From 1948 to 1950, he published three articles containing the educational idea of "developing dentistry into stomatology". When he served as the director of the Faculty of Dentistry of Peking University Medical School in July 1950, he proposed to rename the Faculty of Dentistry into the Faculty of Stomatology,which were approved by the Ministry of Health and the Ministry of Education of the People's Republic of China in one month. The Chinese Medical Association established the Society of Stomatology the next year. Later, dentistry was successively changed into stomatology, and medical content was integrated into dental education, which was of great significance and far-reaching influence. During the developments of the thought of stomatological education in China, Professor Mao Xiejun evidently played a pivotal role. In this paper, the formation process of the thoughts of stomatological education related to professor Mao Xiejun's contribution is elucidated through studying the archives, personal letters, and historical documents, so as to enrich the researches on the history of stomatology in China and to facilitate better understanding and promoting the development of stomatology.

THE DETERMINATION OF HIP CIRCUMFERENCE IN THE MIDDLE OF YOUNG BOYS AND YOUNG GIRLS OF HIGHER EDUCATION INSTITUTIONS OF BUKOVINA DEPENDING ON THE SPORT TYPE.

The aim: To find out the features of the hip circumference in the middle of both extremities by students of higher education institutions of Bukovina, depending on the sport type. Materials and methods: The study of anthropometric parameters was conducted on 115 students of higher education institutions of Bukovina from 16 to 18 years where 78 (67.82%) - young boys and 37 (32.18%) - young girls. The main group of 75 (65.22%) students were represented by the first and the second year students of the Faculty of Physical Culture and Human Health of the Yuriy Fedkovich Chernivtsi National University, and control group consisted of 40 (34.78%) college students and students of the Stomatological Faculty of Bukovynian State Medical University. Among the students of the main group were - 57 (76.0%) young boys and 18 (24.0%) young girls who, in addition to physical activity, which was included in the program of their specialty, additionally engaged in the sports (football players, volleyball players, basketball players, handball players), the control group consisted of 21 (52.5%) young boys and 19 (47.5%) young girls who are busy with hours of physical education, according to the curriculum of their specialty and did not engage in additional sports. Anthropometric examination included the definition of total (height and body weight) parameters and partial (hip circumference in the middle third). Statistical analysis of the data was performed using a licensed program RStudio. Results: Based on the Kraskel-Wallis test, it was found that there is a significant difference in the average length of the hip circumference (in the middle third) on the left depending on the sport. Based on the Conover-Iman test, it was found that there is a significant difference for the pairs «basketball» - «handball», «control» - «handball», «football» - «handball», «volleyball» - «control», «volleyball» - «football», «volleyball» - «handball». Conclusions: The model for predicting the length of the hip circumference (in the middle third) on the right has the form y = β1 + β2 + 0,328 * х1 - 0,167 * х2, on the left it looks like y = β1 + β2 + 0,451 * х1 - 0,179 * х2, where y is the girth of the thigh in the middle third, is the weight, х2 is the height. The coefficient β1 = 58,181 for young girls and β2 = 53,302 for young boys. Coefficient β2 = 0 for the group «basketball», β2 = - 3,358 for the group «control», β2 = - 0,484 for the group «football», β2 = - 1,991 for the group «handball», β2 = - 0,824 for the group «volleyball».

MODERN ASPECTS OF THE PRACTICAL TRAINING OF FUTURE DENTISTS

Abstract. An important and one of the main directions in the field of higher medical education is the necessity of significant strengthening of the practical aspect of training of future doctors and saving the appropriate level of theoretical knowledge.
 The purpose of the study was the studying of the attitude of education seekers when mastering of practical skills at the Department of Children's Therapeutic Dentistry with the use of simulation technologies. A survey was conducted among 137 students of the 4th-5th year of the Stomatological Faculty of the Poltava State Medical University (PDMU). The questionnaire included ten questions, the answers took the subjective feelings of the students into account on this question, that is: effects positively/ yes (%), effects negatively/ no (%), does not affect (%), difficult to answer (%).
 At the department of pediatric therapeutic dentistry, an interactive method of teaching propaedeutics of pediatric therapeutic dentistry, prevention of dental diseases is widely used, and practical skills are improved by students of 4-5 courses in a simulation class with the use of phantoms, mannequins and virtual simulators, which makes it possible to improve the quality of training of students with second to fifth courses. The phantom (simulation) classroom is equipped with 14 workplaces for students.
 According to the results of the conducted anonymous questionnaire, 95.62% of the respondents had a positive attitude to conducting practical classes in the phantom class and 93.43% consider, that it is necessary to organize simulation classes in medical higher education institutions at the departments with the dental profile. 2.92% and 5.11% of respondents find it difficult to answer these questions, but none of the students find a negative impact on the educational process of the presence of simulation classes at the departments.
 Teaches and students consider, that advantages of simulation studying are repeated attempts when mastering a certain practical manipulation. During the questionnaire, 97.08% to 99.3% of students answered positively these questions. From 0.7% to 2,92% of students did not make repeated attempts when mastering dental manipulations. 81,75% of the respondents answered that the practical skills acquired in the simulation class, it has a positive effect on further education at dental departments and when receiving patients. 5,84% answered that it has no effect at all, 1,46% has a negative effect, and 10,95% of students could not answer.
 The application of the modern technologies of simulation training in medical institutions of higher education, especially at dental departments, contributes to the improvement of the quality of the educational process and allows you to master the practical skills necessary for further work. The education seekers positively evaluated the practical skills acquired in the simulation class, which have a positive effect on further education at dental departments and when receiving patients, and considered it necessary to use simulation classes, which allow not only to learn and practice practical manipulations, but also form clinical thinking in future dentists.

The determination of distal hip circumference in universities students depending on the sport type

Purpose: to find out the features of hip girth (distal) of both limbs of young boys and young girls of Bukovynian higher educational institutions, depending on the sport type.
 Materials and methods: 115 students of Bukovynian higher education institutions aged from 16 to 21 years old participated in the study, 78 (67.82%) of them were young boys and 37 (32.18%) were young girls. The main group was 75 (65.22 %) students of the I-II courses of the Faculty of Physical Culture and Human Health (the Yuriy Fedkovich Chernivtsi National University), the control group - 40 (34.78%) college students and students of the Stomatological Faculty of the Bukovynian State Medical University, who underwent an anthropometric study, according to the method of V.V. Bunaka in the modification of P.P. Shaparenko (determination of body weight and hip girth distally).
 Results: a comparison of the length of the distal right and left hip girth of young boys and young girls of both groups shows that the length of the right hip girth of young boys and young girls is bigger than the left: the main group (right in young boys - 48.50±2.0 cm, left - 42.25 ±2.0 cm; right in young girls – 48.59±2.0 cm; left – 41.74±2.0 cm), control group (right in young boys – 49.19±2.0 cm, left – 44 ,42±2.0 cm; young girls' right - 46.57±2.0 cm; left - 41.52±2.0 cm). The conducted regression analysis shows that gender and weight are significant factors for hip girth distally on the right and left.
 Conclusions: the model for predicting the circumference of the distal right thigh has the equation: y = β1+β2 +0.318*x, where y is the distal right thigh circumference, x is weight. Coefficient β1 = 29.848 for young girls and β2 = 25.95 for young boys. The coefficient of determination is 0.994. On the left, it has the equation: y = β1+β2 +0.292*x, where y is the hip girth on the distal left, x is weight. Coefficient β1 = 29.848 for women and β2 = 21.901 for men. The coefficient of determination is 0.991.

100 years – Faculty of Medicine, University of Ljubljana (1919–2019)

The early beginnings of Slovenian medical education take root in the Enlightenment-era Academia operosorum (Academy of the Industrious, 1693–1725) and its medical section with the physician Marko Gerbec, although the Jesuit College introduced higher education in Ljubljana already in 1619. In 1782, a Medico-Surgical Academy was established in Ljubljana, the first to provide a secondary level of medical education. Later on, when a part of present Slovenian lands was included in the Illyrian Provinces (1809–1813) as a part of Napoleon’s French Empire, with Ljubljana as capital, the school advanced to the level of a medical faculty (École Centrale). The subsequent restoration of Austrian sovereignty prevented the school from completing even the first class of graduates’ training. In 1848, Medico-Surgical Academy was dissolved and only midwifery schools remained.
 It was only after disintegration of the Austro-Hungarian Monarchy, as a consequence of the World War I, that in 1919 the first Slovenian University was established in Ljubljana, and within it a incomplete medical faculty was offering four preclinical semesters. In 1940, fifth and sixth semesters were added to the Faculty. The liberation impetus led in July 1945 to the establishment of a complete medical faculty including five years course divided in ten semesters. In the 1949/1950 academic year, the Faculty of Medicine was separated from the University and trained one generation of physicians as a medical college; in 1954, it was reintegrated into the University. During that period, in autumn 1949, the Faculty of Stomatology was established, which soon joined with the Faculty of Medicine, whereupon two departments were established: one for general medicine and one for stomatology (dental medicine). In the 1968/1969 academic year, the Faculty of Medicine introduced a master’s programme, and in 1995 a uniform doctoral programme; in the academic year 1989/1990 the programmes of medicine and dental medicine were extended to twelve semesters.
 In 1975, the new Ljubljana Medical Centre building was finished and the Faculty thus obtained the necessary lecture halls, classrooms, and rooms for clinical practice. In the next decade, in 1987, the main preclinical institutes moved to the new building of the Faculty and students finally received state-of-the-art lab classrooms, facilities, and other infrastructure. In 2015, the Faculty also constructed a new building for preclinical institutes for biochemistry and cell biology. Throughout the years the programme has continued to improve and stay up to date, and the Bologna system of education was introduced in the academic year 2009/2010.
 In its hundred years of existence, the Faculty of Medicine has trained approximately 9,000 physicians and 2,000 dentists, and awarded more than 1,700 doctors of science degrees and more than 1,000 master of science degrees in the postgraduate programme for physicians and dentists; it has also trained many students in graduate clinical training programmes. The Faculty of Medicine is oriented towards the future, a strong connection between theory and practice, interdisciplinary and international cooperation, and especially training new high-quality medical professionals.

Moreover, 62,6 % of students defined TBL as better learning strategy, 54,2 % ‑ more effective in realization of educational goals, 74,70 % and 55,42 % of students pointed out that this method make it possible for better use of study time and discuss more of educational material respectively, 68,67 % and 85,54 % ‑ stimulate the independent study and attention, 65,1 % of respondents consider this method have to use for introducing on practical classes.
 Conclusion. The method of team-based learning have increased learning motivation due to assessment of 81,9 % students.

Frequent postural alterations in patients with different types of temporomandibular disorders

To describe postural alterations according to the type of temporomandibular disorder (TMD). Prior informed consent, 30 patients were included in the study, with a mean age of 27.4 years; 80% women, diagnosed with TMD based on Diagnostic Criteria (DC/ TTM) by a trained researcher in the clinic of the Faculty of Stomatology of the BUAP. Subsequently, a postural analysis (three views) was carried out at the facilities of the School of Physiotherapy of the BUAP using an acetate grid. The results were analyzed with descriptive statistics in the SPSS v20 program. 16.7% of the patients presented muscular TMD, 36.7% joint TMD, and the rest combined TMD. The most common postural alterations were: high shoulder: 93.3%, pelvic tilt: 86.7%, and forward head posture: 83.3%. On average, the patients had between 4 and 5 postural changes. 100% of the patients ha alterations in the side view, while 50% of the patients with TMD of combined origin had alterations in the three views, as well as 45.5% of the patients with TMD of joint origin, and 60% of the patients with TMD of muscular origin. TMD patients present postural changes, mainly forward head posture, pelvic tilt and high shoulder, with special involvement related to muscle and combined diagnosis.

Ipriflavone promotes proliferation and osteogenic differentiation of periodontal ligament cells by activating GPR30/PI3K/AKT signaling pathway.

ObjectivesThis study was performed to investigate the effects and mechanism of ipriflavone (IP) on the proliferation and osteoblastic differentiation of periodontal ligament cells in vitro and periodontal tissue remodeling following orthodontic tooth movement (OTM) in vivo.Materials and methodsHuman periodontal ligament cells (hPDLCs) were cultured in vitro and cell counting kit-8, alkaline phosphatase (ALP) activity assay, plate clone formation assay, and alizarin red staining were used to test proliferation and osteogenic differentiation of hPDLCs. What is more, the expression of ALP, Runx2, and GPR30 was examined by real-time polymerase chain reaction and Western blot. To find out if PI3K/AKT signaling pathway was involved in the process, AKT and p-AKT were examined by Western blot. LY294002 (PI3K signaling pathway inhibitor) and small interfering RNA targeting GPR30 mRNA (siGPR30) were used to verify the function of GPR30-mediated PI3K/AKT pathway in this process. Twenty-four male Wistar rats were randomized into 2 groups, the control group with force application and the IP group with force application plus IP. Morphological changes in the periodontal tissue between roots of teeth were investigated using hematoxylin and eosin (HE) staining and bone morphogenetic protein-2 was detected to assess bone remodeling by immunohistochemical staining.ResultsIn vitro, 10−7 M IP was selected significantly promoting proliferation, ALP activity, colony forming efficiency, and mineral deposition (P<0.05) on hPDLCs. Gene expressions of ALP, Runx2, GPR30, and p-AKT were all upregulated than the control group (P<0.05). According to the mechanism, promotion of ALP and Runx2 interdicted by LY294002 and siGPR30 reduced the activation of PI3K/AKT signaling pathway. In addition, HE staining and immunohistochemical staining results showed that the IP group had more new bone formation in the periodontal tissue compared to the control group in vivo.ConclusionIP can promote the expression of ALP and Runx2 which was probably related to the GPR30-mediated PI3K/AKT signaling pathway. Moreover, IP coordination seemed to have the potential to prevent relapsing following OTM.

Oral health related quality of life and dental status of adult patients

Background: The aim of this study was to assess the oral health related quality of life in adult patients who visit the Dental Clinic of the Faculty of Stomatology, Pancevo, using a Serbian version of 14-items Oral Health Impact Profile (OHIP14) Questionnaire. Material and Methods: A total of 89 respondents (42 women and 47 men, mean age 52.83 ± 13.74 years) filled in the questionnaire themselves. Three calibrated dentists recorded the oral health status of the respondents (number of healthy, decayed, filled and missing teeth), the type and time of wearing prosthodontic replacements, if they existed, and assessed the need for prosthodontic treatment. The total OHIP-14 score was calculated by adding scores for all fourteen items; OHIP-14 subscale scores were calculated by adding the scores for the two items in each of the seven subscales. Results: Mean total OHIP score was 10.25 ± 8.89. Patients with less than eight extracted teeth, wearers of fixed prosthodontic appliances and patients without replacements who did not need prosthodontic treatment reported better oral health-related quality of life. The most severe oral impacts assessed by the subscale OHIP14 scores were recorded in psychological discomfort (2.44 ± 2.18), physical pain (1.87 ± 1.73) and psychological disability subscale (1.83 ± 1.88). Women more often than men were dissatisfied with their diet and had been irritable in contact with other people. Conclusion: Further studies using the OHIP14 questionnaire in a larger sample will permit identification of key factors related to poor oral health and planning of treatment protocols and preventive programs for the adult population in Serbia.

РОЗРАХУНОК АДАПТАЦІЙНОГО ПОТЕНЦІАЛУ, ОЦІНКА АДАПТАЦІЙНИХ МОЖЛИВОСТЕЙ ОРГАНІЗМУ І РІВНІВ ЗДОРОВ’Я СТУДЕНТІВ ЛЬВІВСЬКОГО НАЦІОНАЛЬНОГО МЕДИЧНОГО УНІВЕРСИТЕТУ ІМЕНІ ДАНИЛА ГАЛИЦЬКОГО

Introduction. One of the most important problems of modern physiology and medicine is the investigation of adaptation abilities of human in a way of study the mechanism and the main regularities in the process of body adaptation to various conditions of the environment. During the whole life a modern personality constantly meets with different stressful factors which are connected to social, ecological, psychological and biological changes. The most vulnerable under such conditions are students as the life rhythm of modern students is characterized by a relative hypo dynamics together with considerable intellectual and emotional loading. All those factors together with unbalanced diet and sleep defi ciency have negative effect on psychical, physical and social health of students and also create preconditions for the decrease of adaptation abilities of the body. To deal with the problem of preservation and strengthening of the students’ health it is important to lead a complex examination with the purpose of evaluation of the functioning level of the body systems fi rst of all connected with it. It will give the reason to improve already existing and search for new methods of optimization of functional state, health prevention and future professional longevity of medical students. Aim: To calculate adaptation potential and evaluate adaptation abilities of students together with identifi cation of their health level. Materials and Methods: 98 third-year students of the stomatological faculty of Lviv National Medical University by Danylo Halytsky have taken part in the investigation, 37 of whom were male (37,76 %) and 61 (62,24 %) – female both of whom were nineteen years old at the time of research. All of them according to dispensary cards were not on dispensary registration in connection to any illness and belonged to a group of “almost healthy”. Adaptation potential of cardio-vascular system of the body was identifi ed by R. M. Bayevsky (1979) including the frequency of heart contractions, systolic and diastolic blood pressure, antropometric indices and coeffi cient of the level of plural regression. Results: It has been ascertained that in case of the majority of students under the investigation (57,14 %) the level of adaptation was satisfactory. Among males the quantity of students with satisfactory adaptation and tension of adaptation mechanism was practically the same, whereas in case of females the level of adaptation was satisfactory. It was confi rmed that 87,5 % of sportsmen were referred to the I health group and only 12,5 % to the II health group whereas the proportion to individuals that go in for sports was 63,51 % to 36, 49 %. Conclusion: In case with most students satisfactory level of adaptation is observed. The proportion between the levels of satisfactory adaptation and tension of adaptation mechanisms among boys and girls are different. To be more exact, there were more individuals with satisfactory adaptation among girls rather than boys. It is connected with hormonal differences, less people with harmful habits, more stress resistance and unsatisfactory factors of environment for girls. Individuals who regularly go in for sports have satisfactory adaptation in most cases in comparison to those who do not practice sports. Students included to the I health group were recommended to take general curative procedures such as: the increase of efferent activity, the use of hardening procedure, normalization of nutrition regime, work and rest, cycling, walking, swimming and denial of harmful habits. Those who are in the II health group need not only curative but also prophylactic measures oriented on the prevention of the development of different diseases individually and in every exceptional case. Paying attention to the fact that students are referred to the category of individuals with intensive brain work all of them were explained the necessity of use of psychological methods of rehabilitation such as autogenic trainings except medico biological ones.

НАУКОВО-МЕТОДИЧНІ ОСНОВИ ВИКЛАДАННЯ ФАРМАКОЛОГІЇ ЛІКАРСЬКИХ ЗАСОБІВ, ЩО ВПЛИВАЮТЬ НА ПРОЦЕСИ ЗГОРТАННЯ КРОВІ

Швидкий розвиток фармакологічної науки та поява нових лікарських засобів вимагають постійної зміни програмного матеріалу і вдосконалення методичних підходів до викладання цього матеріалу майбутнім лікарям. Метa роботи – виділити підходи до викладання одного з найбільш складних та важливих розділів фармакології – “Засоби, що впливають на згортання крові” студентам 3-го курсу медичного факультету й 2-го курсу стоматологічного факультету. Аналіз педагогічного досвіду викладачів кафедри фармакології Вінницького національного медичного університету та літературних даних показав, що оптимальним є комплексний підхід. Він включає надання інформації викладачем на лекційних і практичних заняттях (пояснювально-ілюстративний метод), активний самостійний пошук інформації студентом (репродуктивний, проблемний, евристичний методи), а також інноваційні та нетрадиційні методи навчання (наприклад, фармакологічна вікторина). Принцип “від простого до складного” при збереженні послідовності дидактичних підходів викладання, а також правильна організація аудиторної та позааудиторної самостійної роботи студентів дозволяють отримати стабільні і глибокі знання та вміння, навчити його працювати самостійно.

Efficacy of a nAg modified orthodontic primer reducing demineralization around brackets: an in vivo study

Event Abstract Back to Event Efficacy of a nAg modified orthodontic primer reducing demineralization around brackets: an in vivo study Gabriela Moreno-Meraz1, Facundo Ruiz2, Mauricio Pierdant-Pérez3, Antonio A. Gordillo-Moscoso3, Gylmar Mariel-Cárdenas4, Jairo Mariel-Cárdenas5 and Wulfrano Sánchez-Meraz5 1 UASLP, Faculty of Medicine / Faculty of Sciences, Mexico 2 UASLP, Faculty of Sciences, Mexico 3 UASLP, Faculty of Medicine, Mexico 4 UASLP, Faculty of Engineering, Mexico 5 UASLP, Faculty of Stomatology, Mexico Introduction: Tooth enamel, also called enamel tissue or enamel substance way cap covers the dentin in its coronal portion providing protection to the underlying connective tissue. Since enamel composition is based on 95% inorganic matrix it presents a high hardness. Hydroxyapatite crystals are constituted by calcium phosphate, this represents the inorganic component of enamel. Hydroxyapatite crystals are densely packed and are larger than other mineralized tissues. These crystals are susceptible acid substrate, this component is which increases dental demineralization.[1] Dental demineralization is considered to be the most prevalent iatrogenic effect associated with orthodontic treatment and might be jeopardize the longevity and aesthetics of the dental organ associated. It has been documented that the onset and progression of weakness in the enamel surface or dental caries is directly associated with Streptococcus mutans and its prevalence is related to the complexity of itself. It has been clinically proven, that the formation of white opaque spots around braces can occur within the 4 weeks of starting the treatment.[2][3] Silver nanoparticles have demonstrated efficacy as antimicrobials, and some studies have shown that these antimicrobial properties are particularly effective reducing the population of Streptococcus mutans.[4][5][6][7][8] The aim of this study was to compare changes in enamel adjacent to orthodontic brackets using bonding agents enriched with silver nanoparticles (nAg) compared to a conventional primer adhesive with laser fluorescence. Materials and Methods: According with previous studies, Transbond™ XT Primer was doped with silver nanoparticles, A split-mouth design was applied to 20 healthy patients, (40 teeth)[9] who were to begin orthodontic treatment. The brackets were cemented with the nAg doped primer (TX0) randomly allocated to either the right or the left side of the maxilla and it was applied to the incisors following the manufacturer's protocol. The contralateral teeth had the same type of bracket and a conventional primer (TX1) (with no nAg). DIAGNOdent (KaVo Dental Corporation, Lake Zurich, Ill) [10]measurements were used to assess white spot lesions after 8 weeks. This study is registred in the clinical trials page. Results: All analyses were performed with R software version 3.1.0 and R Commander version 2.0-4 package 95% confidence level. [11]There were no missing observations. To determine the effectiveness of treatment, an analysis of the final measurements an ANOVA was performed. The final model (Demineralizatión~Basal + Tx) was significant F (39) = 31.4, p <0.001. It can be explained 63% of the variation in the set of explanatory variables. The mean in FINAL score when TX0 = 3.25 + 1.99 is lower than the mean of FINAL score when TX1 = 9.85 + 6.39. The difference in scores between the two groups is 6.13 (CI 95%, 3.82 - 8.43). Conclusion: Baseline measurements for both treatments showed demineralization degree as the initial score taken with diagnodent. However, the difference in baseline mean was not significant. The teeth, which were primed with nAg doped Transbond XT, had lower final mean score than those primed with conventional Transbond XT, at 8 weeks from baseline measure. This may be attributed to the antimicrobial effect of silver nanoparticles and this effect is not modified after curing the primer. Other studies to evaluate the type of bracket, and to evaluate whether increasing the amount of nanoparticles, the antimicrobial power of the primer is increased without changing its physical properties, and if it persists over time. are needed.

Effectivity of a fluoride varnish with silver nanoparticles for enamel remineralisation in patients with trisomy 21

Event Abstract Back to Event Effectivity of a fluoride varnish with silver nanoparticles for enamel remineralisation in patients with trisomy 21 America S. Mares-Garcia1, Claudia Butron-Tellez2, Mauricio Pierdant-Perez1, Jairo Mariel-Cardenas1, Gabriela Moreno-Meraz2, Jose L. Ramirez-Garcia-Luna2 and Antonio A. Gordillo-Moscoso1 1 Universidad Autonoma de San Luis Potosí, Faculty of MEDICINE, Mexico 2 Universidad Autonoma de San Luis Potosí, Faculty of Stomatology, Mexico Children with trisomy 21 exhibit oral health abnormalities that confer higher risk for caries development. Fluorinated varnishes have been used as a preventive method for this pathology, and in the treatment of dental lesions with white spots, considered the first stage of these lesions. Silver nanoparticles have demonstrated to exert a bactericidal effect against oral pathogens, without pigmentation of the dental enamel and with no evidence of toxicity. To assess the affectivity of the combination of these strategies, a randomized controlled double-blind trial with a split-plot design was performed in 22 children with white spots on both maxillary dental teeth. One tooth received three applications of a fluoride varnish with silver nanoparticles, and the other one, three applications of the same varnish without nanoparticles. We measured the mineral content of the teeth with a laser cavity detection pen after the first application of the varnishes, and 3 months after the last application to assess the degree of mineralization of the tissue. We found significant differences between teeth treated with and without silver nanoparticles; teeth treated with the varnish with silver nanoparticles appeared to be more mineralised. Treatment with a fluoride varnish with silver nanoparticles is more effective to promote dental remineralisation of teeth affected with white spot lesions in children with trisomy 21. This strategy may be used as a prophylactic measure to avoid development of caries and to improve oral health in this population.
