THE INCREASE OF RESISTANCE OF HARD TISSUES OF TEETH WITH NON-CARIOUS LESIONS OF TEETH

"Perfection is achieved not when there is nothing to add, but when there is nothing to remove" Antoine de Saint-Exupery Presents the results of a study of the performance of aesthetic and artistic restorations and the study of these dental restorations after a certain time with the naked eye and binoculars of two types, while the use of a SLR camera was a prerequisite. Comparative analysis has shown that the use of optical systems during dental manipulations significantly improves the diagnosis of carious and non-carious lesions, facilitates work and reduces the risk of various complications. Clinical photographs are an important component of aesthetic dentistry.

Objective: This work aims to use new spectroscopic and radiographic methods to study the dental hard tissue erosion and abfraction, as these lesions are actually quite difficult to be diagnosed in clinical practice. Material and Methods: This in vivo study was conducted on 60 patients with early erosion and 60 patients with abfraction at the cervical area by means of laser-induced fluorescence (LIF) and multilayer spiral computed tomography (MSCT). Results: In comparative dental hard tissues studies LIF spectra from intact and affected areas, it was noted multidirectional fluorescence intensity dependence between areas affected by abfraction and intact areas. MSCT technique allowed assessing the degree of damaged areas, especially at deeper stages. Conclusion: Although LIF and MSCT methods presented limitations, it was shown their effectiveness in the diagnosis of abfraction and erosion by detecting changes in the morphological structure as well as in the chemical and mineral composition of affected dental hard tissues. So LIF and MSCT methods can be successfully used in order to develop new medical devices which will provide most accurate clinical diagnose of different stages of dental erosion and abfraction.KEYWORDSFluorescence spectroscopy; Spiral computed tomography; Tooth demineralization; Tooth erosion.

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.

The problem of hard tissues of teeth discoloration treatment is relevant for modern practical dentistry due to the widespread use of endodontic treatment of anterior teeth, dental preservation operations and therapeutic treatment of caries and non-carious lesions of hard tissues of teeth. Teeth discoloration quite often happens as a complication of endodontic treatment, injuries, secondary caries and other lesions of hard tissues. The article describes a clinical case of the removal of discoloration of the front teeth of the upper jaw (after a tooth-preserving operation and previously performed tooth restorations) using the modern photopolymer composites material «Jen-Radiance» and «Jen-Favorite LC» made in Ukraine.

Abstract Introduction. Numerous clinical symptoms found in patients with temporomandibular disorders include non-carious lesions, such as V-shaped lesions, wear facets, enamel cracks, and impressions on the tongue or changes in the buccal mucosa. In addition, loosening and dislocation of teeth may occur. Aim. The aim of the study was to obtain a clinical assessment of the prevalence and severity of non-carious lesions of dental hard tissues (attrition and abrasion) in patients treated for functional temporomandibular disorders. Material and methods. The clinical research was performed among 45 patients of both genders, aged 16-38 years, treated at the Department of Functional Masticatory Disorders at the Medical University of Lublin, Poland. The study group consisted of 30 patients with diagnosed temporomandibular disorders. The control group included 15 individuals with no diagnosed temporomandibular disorders. The control group was selected using the method of analogues (considering age, gender and dental status). The examinations were performed before the treatment and twelve weeks after its beginning. Results. The study found significantly higher values of the prevalence and severity of attrition in the patients group, in comparison with the control group (p < 0.05). In the case of abrasion, higher values of the studied variables of prevalence and severity of lesions in the patients, compared to controls, were also found, but the differences were not statistically significant (p > 0.05). Conclusions. Attrition occurs more frequently and is more severe in patients with diagnosed temporomandibular disorders than in those without such diagnosis. However, no significant differences have been found in the prevalence and severity of abrasion in both groups.

The purpose of the study is a quantitative assessment of the yield of dentinal fluid on the surface of the treated dentin of the tooth when restoring its structure with a composite filling material. To achieve this goal, digital images of the coronal parts of the teeth having formed carious cavities were used; virtual models of hard tissues of teeth recreated using specialized computer programs; A computer program that provides the ability to accurately determine the area of the treated dentin tooth. The results made it possible to draw the following conclusions: with an increase in the depth of the carious cavity, the amount of dentin fluid that can stand out on its surface (1–2 mm from the tooth cavity) sharply increases; with an increase in the area of the formed carious cavity (more than 30 mm2), the risk of release of a critical mass of dentinal fluid (more than 0.4 mg), which can adversely affect the strength of the adhesive interaction between the composite material and the hard tissues of the tooth, increases significantly; the same dynamics is observed with increasing time, at which there is the possibility of free exit of dentinal fluid to the surface of the cavity prepared for filling (more than 45 seconds).

One of the non-invasive methods for treating discoloration of hard tooth tissues is teeth whitening. The aim of this work is to assess the dynamics of changes in the acid resistance of enamel and hard tissues of teeth and the rate of its remineralization after the procedure of office teeth whitening. The study involved 123 patients aged 18 to 35 years with discoloration of various origins, with the color of hard tooth tissues on the Vita Classic A2 scale and darker. Before performing the office, teeth whitening procedure, all patients gave their written voluntary informed consent to participate in this study, as well as consent to the processing of personal data. Depending on the chosen method of office teeth whitening, patients were divided into 3 groups. The resistance of hard tooth tissues was judged based on the determination of TOER and CASRE tests. These indicators were determined at various times (5 days before the office teeth whitening procedure, 5 days after it, after 14, 30 days and 6 months). Regardless of the chosen whitening system, the office teeth whitening procedure is accompanied by a decrease in the enamel's resistance to acids and a decrease in the rate of its remineralization. The remineralizing function of oral fluid promotes the positive dynamics of the studied parameters after 14 days and after 30 days values increased due to the appointment of remineralizing therapy to all patients in 2 weeks after the teeth whitening procedure. After 6 months, all patients had high enamel resistance and the rate of its remineralization.
