Advances in Dental Materials through Nanotechnology: Facts, Perspectives and Toxicological Aspects.

The emerging field of nanostructured implants has enormous scope in the areas of medical science and dental implants. Surface nanofeatures provide significant potential solutions to medical problems by the introduction of better biomaterials, improved implant design, and surface engineering techniques such as coating, patterning, functionalization and molecular grafting at the nanoscale. This review is of an interdisciplinary nature, addressing the history and development of dental implants and the emerging area of nanotechnology in dental implants. After a brief introduction to nanotechnology in dental implants and the main classes of dental implants, an overview of different types of nanomaterials (i.e. metals, metal oxides, ceramics, polymers and hydrides) used in dental implant together with their unique properties, the influence of elemental compositions, and surface morphologies and possible applications are presented from a chemical point of view. In the core of this review, the dental implant materials, physical and chemical fabrication techniques and the role of nanotechnology in achieving ideal dental implants have been discussed. Finally, the critical parameters in dental implant design and available data on the current dental implant surfaces that use nanotopography in clinical dentistry have been discussed.

Chupryna R. R. Prevention of menopausal disorders in women with unspecified benign uterine or ovarian tumors. – Manuscript. Thesis for academic degree of candidate of medical sciences in specialty 14.01.01 – Obstetrics and Gynecology. – P. L. Shupyk National Medical Academy of Post-Graduate Education, Kyiv, 2015. The paper deals with the peculiarities of preventive measures aimed at reducing menopausal disorders in women with unspecified benign uterine or ovarian tumors. Diagnostic criteria for early and late complications of natural and surgical menopause have been developed by studying the clinical course of the above conditions and the homeostasis system in the examined patients. Based on comprehensive clinical, lab and instrumental examination of women with unspecified benign uterine or ovarian tumors, the author provides a scientifically justified

The human body comprises molecules; hence, the availability of molecular nanotechnology will permit dramatic progress to address medical problems and will use molecular knowledge to maintain and improve human health at the molecular scale. Nanomedicine could develop devices that are able to work inside the human body in order to identify the early presence of a disease, and to identify and quantify toxic molecules and tumor cells, for example. Nanodentistry will make possible the maintenance of comprehensive oral health by employing nanomaterials, including tissue engineering and, ultimately, dental nanorobots. This review is an attempt to highlight the possible applications of nanotechnology and the use of nanomaterials in dentistry.

Background: Periodontal subgingival pathogens affect local and systemic immune responses and initiate an acute phase systemic inflammatory response characterized by the release of C-reactive proteins (CRPs). This study has been carried out to evaluate the serum concentration of CRPs, which can be used as a marker of periodontal disease as well as a risk indicator for cardiovascular diseases. Materials and Methods: In a retrospective study a total number of 45 subjects were selected from the outpatient department of periodontics a mean age of 40 years. Based on the periodontal status, the subjects were divided into 3 groups of 15 subjects each. Group I: Control group [with attachment loss (AL) ≤ 2 mm and pocket depth (PD) < 3 mm], Group II: Generalized aggressive periodontitis (AL ≤ 5 mm), Group III: chronic periodontitis (AL ≥ 2 mm, PD ≥ 5 mm), which includes moderate and severe periodontitis. The clinical parameters recorded were plaque index,gingival index, bleeding index, probing PD, and clinical attachment levels and scoring was done on 6 surfaces of all teeth. For the CRP assessment, blood samples were collected from subjects at the time of clinical examination. Analysis of covariance was used for comparison of mean values between the groups to adjust the ages (P value < 0.05). Results: Overall, the mean CRP levels were high in subjects with generalized aggressive and chronic periodontitis compared with controls. This was found to be statistically significant. A statistically significant difference (P = 0.012) was found in the CRP level between groups I and II and between groups II and III, and between groups I and III. Conclusion: The results of the present study indicated an increase in serum CRP levels in subjects with generalized aggressive periodontitis and chronic periodontitis as compared with the controls.

Evaluation of serum C-reactive protein levels in subjects with aggressive and chronic periodontitis and comparison with healthy controls.

Periodontal subgingival pathogens affect local and systemic immune and inflammatory response and cause the release of cytokines; this results in periodontal destruction and initiation of an acute phase systemic inflammatory response characterized by the release of C-reactive proteins (CRP). This study set out to evaluate the serum concentration of CRP that can be used as a marker of periodontal disease as well as a risk indicator for cardiovascular disease. Based on their periodontal status, 45 patients were divided into three groups. The following clinical parameters were recorded: plaque index, gingival index, bleeding index, probing pocket depth, and clinical attachment levels. Scoring was done on six tooth surfaces for all teeth. For the CRP assessment, blood samples were collected from subjects at the time of clinical examination. The results indicated an increase in serum CRP levels in patients with generalized aggressive periodontitis and chronic periodontitis as compared to controls.

Objective: The study was conducted to assess the postural awareness of dental students in Jizan, Saudi Arabia. Materials and Methods: Close-ended, self-administered questionnaires were used for data collection in the survey. The questionnaire was prepared by observing the positions of students working in the clinics and the common mistakes they make with regard to their postures. The questionnaires were distributed among the dental students who were present and reported to work in the clinics. Levels of postural awareness and the relationship between postural awareness and the degree of musculoskeletal disorder (MSD) among the students was evaluated. This study was carried out in the College of Dental Sciences and Hospital, Jizan. Statistical Analysis: The level of knowledge of postural awareness was evaluated and correlated with the presence or absence of the MSDs. Categorical variables were compared using Chi-square test. P values of less than 0.05 were considered statistically significant. Results: A total of 162 dental students from the age group of 20–25 years were included in the survey, of which 134 dentists responded (83%). When their postural awareness was evaluated, results showed that 89% of the students had poor-to-medium levels of postural awareness. The relation between postural awareness and prevalence of MSDs indicated that 75% of the students with poor awareness, 49% of the students with average awareness, and 40% of the students with good awareness have MSDs. The results were statistically significant (0.002127, which is <0.005) stating that better awareness about proper postures while working helps to minimize the risk of MSDs. Conclusion: Evaluation of levels of postural awareness showed that 21% of the students had poor postural awareness, 67% had average awareness, and 11% had good postural awareness. The analysis of results showed that those students with low-to-average postural awareness had significantly greater prevalence of MSDs.
