Index Estimation

Resistance of tooth enamel to aggressive effect of metabolic by-products of oral cavity microorganisms is provided by fluoroapatites of enamel surface layers. The patients were divided into two groups: control group (30 females) and experimental (observa-tion) group (30 females). In control group, the traditional method of caries prevention was used, which included professional teeth cleaning, mouthwash with physiological solution (0.9%) of sodium chloride after meals, hygienic teeth brushing by a standard method twice a day. Females of experimental group underwent professional teeth cleaning, treatment of teeth with the drug product containing sodium fluoride to in-crease the resistance of hard tissues of teeth, silver nitrate and decamethoxin, rinsing with standardized decamethoxin solution. Various indices are used in modern den-tistry to evaluate oral hygiene status. Index estimation provides quantitative charac-teristics of static status of oral hygiene. Their values enable to suggest the course of inflammatory-destructive or dystrophic process and its severity, to evaluate treatment efficacy and quality of regular check-up of a particular patient or dispensary cases. The study demonstrated significant positive clinical efficacy of the drug product used to increase resistance of dental hard tissues. In particular, patients using the pharma-ceutical preparation to improve the resistance of dental hard tissues, had significantly lower values of Fedorov-Volodkina’s Index, Greene-Vermillion Index (Oral Hygiene Index- Simplified), Patient Hygiene Performance (PHP) Index as compared to the control group.

Abstract Tooth plates of the chimaeroids, holocephalian fishes, are unique dental hard tissues. Unlike the teeth of other animals, the tooth plates are located on the roof of the mouth and in the lower jaw. Their tooth plates consist, to a large extent, of lightly mineralized tissue (osteodentin) and hypermineralized tissue (pleromin). Notably, the mineral phase of pleromin is whitlockite, while that of other animals is apatite. Dietary habits of chimaeroids and wearing features of their tooth plates suggest an extreme hardness of pleromin, but this has never been investigated. We examined the microhardness of the tooth plate of Chimaera phantasma and found that pleromin in the biting region was extremely hard, comparable with the hardness of mature tooth enamel, whereas the hardness of immature pleromin was lower than that of bovine dentin. The hardness of osteodentin, on the other hand, was equivalent to that of bovine dentin and almost the same throughout the tooth plate. Immature pleromin was sparsely packed with oval crystals of whitlockite and, as pleromin matures, the space between crystals was filled with small intercrystalline materials. The maturing process of pleromin could partly contribute to its remarkable hardness and have some implications for designing novel biomaterials.

It is vitally crucial for dentists to increase the quality of personal hygiene among their patients because oral hygiene is the key method of initial preventive action against oral diseases.Our aim is to increase the quality of personal oral hygiene among students of dentistry. We defned the effciency of plaque removal by sonic powered toothbrushes (SPT – the observation groups) and manual toothbrushes (MT – the control group) with OHI-S – oral hygiene index simplifed and Loe-Silness Gingival index. Based on comparison of the hygiene index results we evaluated the dynamics digital changes before, during and after the examination.Results of the study. The result of the observation group (Sonic Powered Toothbrush – SPT) is 32.4% higher in comparison with MT based on Loe-Silness Gingival index. The cleaning effciency of SPT by the values of OHI-S was 88.01 ± 0.24%; MT – 25.40 ±0.13%. This indicated that plaque removal was 62.7% more effcient among the participants using SPT.Findings. The participants of the experiment were in absolutely similar terms, used the same toothpaste; however SPT decreased plaque more effectively than MT in everyday use in studies lasting up to three months.

The aim of this study was to compare the oral health status and salivary antioxidant system between patients diagnosed with anorexia nervosa (AN) and healthy controls. A total of 25 female AN patients and 25 matched healthy controls were enrolled. Clinical parameters and saliva samples were collected for each patient. Two questionnaires to investigate oral health and hygiene were administered. Superoxide Dismutase (SOD) activity and High Reactive Oxygen Species (hROS) were evaluated. Salivary concentration of SOD was significantly higher in subjects with AN compared with control group (1.010 ± 0.462 vs. 0.579 ± 0.296 U/mL; p = 0.0003). No significant differences between groups were identified for hROS (233.72 ± 88.27 vs. 199.49 ± 74.72; p = 0.15). Data from questionnaires indicated that, although most of the patients recognized the oral hygiene importance in maintaining a good oral health, more than half of them had poor oral hygiene. Altered biochemical composition of saliva in patients with AN could be interpreted as an effective defence mechanism against oxidative stress. Moreover, despite the discrepancy between clinical findings and perception of the oral health in AN population arose, the quality of life of these patients appears not to be significantly affected by their dental condition.

The Difference

Introduction. Supra-occlusion is a position of a group of teeth or individual teeth, the cutting edge or chewing surface of which is located above the occlusal plane. This condition is characterized as primary traumatic occlusion, supra-contact or traumatic nodes, in which a number of structural and functional changes occur in the hard tissues of the teeth and periodontal tissue. Traumatic occlusion of teeth is often caused by occlusal intervention, such as high fillings or prostheses, parafunctional habits. In physiological conditions, the protection of teeth from chemical and mechanical interventions is provided by their structural and functional resistance. However, the influence of supra-occlusion on the resistance of tooth enamel, and especially in different age groups, has not yet been studied. Therefore, we consider this topic relevant. The objective of the work was to study the state of enamel resistance in supra-occlusal contacts of individual teeth in rats of various ages according to the enamel resistance test (ERT-test). Materials and methods. The study involved 36 white male laboratory rats aged 4 to 22 months and weighing 100 to 210 g. The animals were divided into two groups (control and experimental), each was divided into three subgroups (6 animals each) according to age categories: young, mature, old-aged. In the study group, the state of supra-occlusion was simulated by increasing the height of the lower right second molars via filling 1 mm in height, without preparation of hard tissues of the teeth. Previously, the animals were anesthetized intramuscularly with sodium thiopental solution. After removing the animals from the experiment on the 15th day by decapitation under general anesthesia with sodium thiopental, by intraperitoneal injection, the dental blocks were removed and the structural and functional state of the tooth enamel was determined by the ERT-test. Statistical processing of data was performed using the program AtteStat V.12.5 with the determination of the mean and its error (M ± m). The probable significance of the difference in the obtained data was determined by the Student's t-test (p ≤ 0.05). Study results. In the control group, ERT-test values decreased (enamel resistance increased accordingly) in rats, depending on age. In young rats, enamel resistance to acidic dissolution was the smallest, and in mature and old-aged rats it increased. However, the difference between the age groups was not statistically significant (p > 0.05). A similar situation was registered in animals of the study group. However, statistically significant differences were observed only between young and old-aged rats (p = 0.025). In the control group, the acid resistance of enamel is higher compared to study group (p = 0.007). In young rats from the control group, enamel resistance to acids was 16.7% higher than in the study group (p = 0.025). In mature animals of the control group, the resistance of enamel to acid dissolution is 17.7% higher than in the study group (p = 0.046), and in old-aged – by 15.2% (p = 0.2). Conclusions. The resistance of enamel of teeth that are subjected to increased stress via supra-occlusal interactions is reduced in young, mature and old-aged rats in comparison with the control group. Reduced enamel resistance can be one of the risk factors in the occurrence of dental caries.

The purpose of our study was to determine the intensity of dental caries and the level of oral hygiene in boys and girls, depending on age and conducting remineralizative therapy in the observed group of children with the aim of prevention of dental caries. The study was carried out with the informed consent of parents of examining children. We carried out dental examination of 60 schoolchildren in Vinnytsya, aged 6–8 years old, who were divided into two even groups, near 30 persons in evey group who was provided remineralizative therapy of dental hard tissue using the preparation “Bifluorid 10” VOCO (Germany). In the article the clinical discussion of high efficiency of preventive remineralizative therapy of dental hard tissues in children 6-8 years is presented. According to the results of the primary examination in the observed children, it was found that the average of oral hygiene index of Fedorova-Volodkina was 2.3±0.16 scores in the main group and 2.31±0.13 scores in the control group, which indicates an unsatisfactory level of oral hygiene in both groups. Dental caries was determined in 100% of cases among the examined children, caries intensity indexes DMFT+df were corresponded to 5.57±1.04 in the main group and 5.7±0.95 in the control group. The intensity of the color of the TER-test in the basic observation was — 3.88±0.75 in the main group and 4.19±0.91 the control group. The oral hygiene index slightly increased after 12 months of research. In children of the main group it was 1.52±0.12 and 1.58±0.15 in the control group, which corresponds to satisfactory oral hygiene. However, in general, during the period of our investigation, the oral hygiene index was significantly improved in comparing to the primary scores on 33.9% in the main group and on 31.64% in the control group. The index of growth of caries intensity was — 7 (23%) in the control group and in the main group — 1 (3.3%) in the main one. The parameters of the TER test were within the range of 2.1±0.3 scores in the basic and 3.93±0.7 scores in the control groups, which corresponds to the improvement of the mineralization of the dental hard tissue (p <0.05). Consequently, the problem of high dental caries intensity and caries prevalence of primary and permanent teeth suggests about cariogenic situation in the oral cavity of children during the period of the eruption of the first permanent molars. Professional oral hygiene, the formation of regular oral hygienic habits, deep fluoridation using the Bifluorid 10 VOCO (Germany), not only improve the oral hygiene status, but also reduce the growth index of dental caries and have a high efficiency of prevention of dental caries.

SummaryOrthodontic treatment of dentoalveolar anomalies is car-ried out using fixed and removable appliances, which af-fects the homeostasis of the oral cavity and increases the risk of developing carious lesions of the enamel. Purpose of the study: comparative assessment of the level of oral hygiene and the prevalence of enamel carious lesions at the stage of orthodontic treatment using removable and non-removable appliances. Materials and methods:90 patients aged 18 to 35 years were examined: 45 patients of the 1st group, who were treated with aligners, and 45 patientsof the second group, who were treated with a bracket system. In all patients, the level of oral hygiene was determined by the OHI-S (Green-Vermillion) index, as well as the level of CPU before and after 12 months of orthodontic treatment. Results: before the start of orth-odontic treatment, the OHI-S index in patients of the first and second groups was 0.86±0.67 and 0.89±0.74 points, respectively. After 12 months, there was a deterioration in the parameters of oral hygiene to a greater extent in patients of the second group who were treated with a fixed technique: the OHI-S index was 1.98±0.79 points. The value of the CPU index before the start of orthodontic treatment in patients of the first and second groups was 7.1±1.32 and 6.9±1.46, respectively. After 12 months of orthodontic treatment, there was an increase in the CPU index in the studied persons of the second group, who were treated with a bracket system: the CPU index was 13.6±1.78. In patients of the first group, the CPU indica-tor practically did not change and amounted to 7.9±1.25. Conclusion: with high caries susceptibility and the pre-sence of non-carious enamel lesions, orthodontic treat-ment with removable appliances should be preferred in order to avoid the development of complications.

AbstractThe study aimed to evaluate oral health in women with eating disorders. The clinical study covered 30 patients aged 14-36 years suffering from diagnosed eating disorders and treated in closed psychiatric institutions. The control group comprised 30 healthy women at the mean age corresponding to that of the patient group. No relationships were confirmed between eating disorders and the intensity of dental caries. Eating disorders contribute to increased loss of dental hard tissues. In women suffering from eating disorders non-specific lesions in oral cavity are more common than in healthy women.

Aim. Evaluation of the effective preventive methods of dental caries in children with dentoalveolar anomalies. Methods. Orthodontic treatment was received by 50 children aged 12-14 years with dentoalveolar anomalies who were treated by an orthodontist using ligature bracket and who had a compensated form of dental caries before the beginning of the hardware treatment. In the first group of children (control, 25 subjects) professional oral hygiene twice a year was followed by the coating of all teeth with fluoride. Children of the second group (25 subjects) after professional oral hygiene twice a year had their teeth covered with tooth enamel around brackets with Clinpro XT Varnish (3M ESPE) material containing fluorine, calcium and phosphate compounds. Dental examination every three months included assessment of oral hygiene and the state of the gums, the presence of carious defects, fillings and removed teeth, followed by the calculation of the main dental indices. Results. On the basis of studies of the dental status in children undergoing orthodontic treatment using brackets, the main dental indices such as DCF (decay/missing/filled), complex periodontal index, papillary-marginal-alveolar index were characterized at the stages of treatment. The analysis of the recorded values was performed in the comparison groups for each research method and the main statistically significant differences were identified. The study revealed that children from group 2 had positive dynamics of the state of periodontium within 18 months: the value of papillary-marginal-alveolar index among children from group 2 decreased by 5.4 times, the value of complex periodontal index decreased by 3.5 times. Children from group 2 had a significantly lower incidence of caries compared to the control group after 18 months of remineralizing therapy: the increase of complex periodontal index among children receiving orthodontic treatment with Clinpro XT Varnish coverage twice a year was only 1.42±0.16, incidence of caries of teeth surface reduced by 55%. Conclusion. On the basis of these studies, a comparative characteristics of the dental indices was performed at the stages of treatment using the brackets, depending on the used primary preventive measures; dental status of children at the stages of orthodontic treatment have their features: special oral hygiene tools should be guided by hygiene indices and complemented by remineralizing drugs.

Giving MSG can reduce the morphological quality, motility, and count of spermatozoa. Propoelix extract as an antioxidant is evidently capable of a non-enzymatic radical scavenger. This research aims at evaluating the effect of propoelix extract administration on sperm quality of MSG-induced male Wistar rats. Employing the post the only control group design, 18 rats aged 3 months were divided into 3 random groups, weighing ±250 gram. Propoelix extract was given orally for 21 days and on 22 days, cauda epididymis until the ampulla of vas deferens was cut in a glass jar that has been given 0,5 cc of 0,9% physiological solution. The result of spermatozoa morphology (%) in group K (54,5) group P1 (65) group P2 (76) was significantly higher, p < 0,05. Spermatozoa motility (%) in group K (41.3) group P1 (53.8) group P2 (65.3) were significantly higher, p < 0.05. The number of spermatozoa cells (million/ml) in group K (2.65), group P1 (3.63), group P2 (4.91) was significantly higher, p < 0.05. Conculatition of propoelix extract was able to improve the quality of the morphology, motility, and the count of spermatozoa of MSG-induced male Wistar rats.

Abstract Aim This report presents an unusual case of regional odontodysplasia (RO) in the mandible which crosses the midline along with its clinical management. Background RO is an uncommon, nonhereditary unilateral developmental anomaly involving the dental hard tissues, most frequently affecting the maxillary teeth. Report RO was diagnosed in a 12-year-old. The dysplastic teeth were the mandibular canines, lateral incisors, central incisors, and the right premolars. The treatment was extraction of the affected teeth followed by provisory prosthetic rehabilitation. Summary The etiology of RO remains obscure. In this case a possible association with pre-natal trauma is suspected. The literature is not unanimous as to the management of RO. Nevertheless, the presence of a dental abscess is an indication for extraction. Since general bone quality is not affected, a provisory prosthesis was fabricated as the patient waits for future implant rehabilitation. The executed treatment met the expectations of the patient and her mother as it improved the patient's masticatory function, esthetics, and quality of life. Clinical Significance The general practitioner must be prepared to deal with different situations in the dental office. The diagnosis of RO relies mainly on clinical and radiographic findings, and its treatment depends on the affected teeth, the severity of the dysplasia, the presence of infection, and the patient's age.
