Clinical Investigation

Statistical evaluation of the frequency of therapeutic and diagnostic devices used by prosthetic dentists for pathology of the temporomandibular joint
Privalova A.V., Leshcheva E.A.
Abstract

BACKGROUND: Occlusal splints are commonly used for treating myofascial and temporomandibular joint (TMJ) disorders. The success of their application depends on the knowledge of prosthetic dentists regarding TMJ disorders, device type used, splint manufacture method, treatment duration, and other factors.

AIM: This study aimed to explore various approaches of prosthetic dentists to the diagnosis of myofascial disorders, bruxism, and TMG disorders and evaluate the methods of therapy used in clinical practice.

MATERIALS AND METHODS: A survey and questionnaire was conducted among orthopedic dentists in the city of Voronezh working in private or state dental organizations, on the topic “Pathology of the temporomandibular joint and methods of therapy”. The question list consisting of 15 questions was developed for statistical evaluation of therapeutic and diagnostic constructions used by prosthetic dentists in their clinical practice in cases related to the pathology of the TMJ. During this study, specially designed questionnaires were filled out. Furthermore, the conversation with each participant was conducted for a direct analysis of orthopedic measures of TMJ disorders.

To analyze the obtained values, the criterion χ2 or Pearson’s criterion of agreement, Fisher’s exact criterion, and Kramer’s V criterion were used. The confidence interval was set to 95%.

RESULTS: Among the surveyed doctors, 78 (65.0%) had more than 15 years of experience, 27 (22.5%) had 5–15 years of experience, and 15 (12.5%) had less than 5 years of experience. When using a single-sample binomial criterion, the number of doctors working in different institutions significantly differed (p <0.001). Thus, majority of the surveyed doctors (n=102; 85%) worked in state-funded clinics and the remaining (n=18; 15%) in private clinics (p <0.001). Moreover, 25 respondents (20.8%) claimed that they do not use tires in their practice, whereas the remaining 95 (79.2%) do.

CONCLUSIONS: The participation of prosthetic dentists in this study demonstrated their high interest in “Pathology of the temporomandibular joint and methods of therapy”. The results of the survey indicate a change in the level of dentists’ knowledge with increasing professional experience. The methods of therapy used by the study participants considerably differ and often do not comply with the basic recommendations of the Dental Association of Russia.

Influence of the volume of surgical intervention on the severity of pain in patients after orthognathic surgery
Galazov A.T., Drobyshev A.Y., Redko N.A., Klipa I.A., Mikhailyukov V.M., Sviridov E.G., Azieva T.R., Drobysheva N.S.
Abstract

BACKGROUND: The treatment of patients with jaw abnormalities involves orthognathic surgery, a consequence of which is postoperative pain. Considerable research is allocated to the study of pain and its management because pain affects the comfort of patients during rehabilitation. Currently, the factors that are responsible for the severity of postoperative pain syndrome remains debatable. Additionally, before surgical treatment, patients are concerned about the intensity of postoperative pain and its relationship with the extent of surgery. Owing to existing disagreements, primarily regarding the relationship between the volume of surgical intervention and the intensity of pain, conducting this study is critical.

AIM: To identify factors that directly influence postoperative pain experienced by patients.

MATERIALS AND METHODS: Pain intensity in patients on day 2 following orthognathic surgery was measured using visual analog scale (VAS).

RESULTS: During the study, patients after orthognathic surgery were divided into groups based on the extent of surgery, sex, age, and duration of surgery to compare their VAS pain intensity scores. No significant difference was found in the average VAS scores of patients’ pain intensity (p >0.05) between the groups.

CONCLUSION: The volume and duration of orthognathic surgery, age, and sex of the patients did not affect the intensity of pain.

The use of raman-fluorescent medical technologies to assess the effect of physical and chemical factors on the mineralization of hard tooth tissues in normal and noncarious lesions
Aleksandrov M.T., Podoynikova M.N., Eganian D.G.
Abstract

BACKGROUND: Assessment of the rapid state of mineralization of hard tooth tissues in normal and in various carious and noncarious lesions based on objective in situ methods is an unsolved and urgent issue in dental science and practice.

AIM: To substantiate the need for the clinical application in situ of express digital raman-fluorescent technology to increase the objectivity and effectiveness of assessing the degree of mineralization of hard tooth tissues in carious (initial form) and noncarious (wedge-shaped defect, pathological erasability) lesions under the influence of various physical and chemical factors on tissues.

MATERIALS AND METHODS: A survey of 80 patients aged 25–50 years was conducted; the patients were divided into three groups: comparison and with carious and with noncarious (wedge-shaped defect, pathological erasability) lesions of hard dental tissues. In each group, changes in hygienic conditions and mineralization parameters of hard tooth tissues were assessed by the difference in the spectral intensity of raman-fluorescent measurements before and after controlled and/or uncontrolled hygienic treatment. Previously, under experimental conditions, the effects of various physical (mechanical processing, X-ray irradiation on the LNK-268 installation) and chemical (citric acid, hydroxylapatite (GAP) dry and moistened) factors on the hard tissues of the tooth were studied. Simultaneously, “locally” in real time, the mineralization parameters of the hard tissues of the tooth were recorded before and after hygienic treatment. In this study, we used an installation of the “InSpectrM” type in our modification.

RESULTS: Experimental studies have shown the effectiveness and objectivity of the use of raman-fluorescence diagnostics to assess the hygienic condition and mineralization of hard dental tissues. The objectivity of the assessment of mineralization in a moistened state was investigated (dry GAP, 702 rel. units; wet GAP, 1520 rel. units), and the absence of the effect of radiation on the mineralization of hard tissues of the teeth (p >0.95) was revealed.

Clinical observations showed that in patients with a wedge-shaped defect and increased erasability of hard tooth tissues, the hygienic condition is 5–10% worse than that in patients with intact tooth tissues and initial formation of caries. The main difference in the condition of hard tissues of teeth with noncarious lesions is a statistically significantly reduced (p >0.95) mineralization of hard tissues of the tooth, requiring remineralizing therapy immediately after hygienic treatment.

CONCLUSION: In experimental and clinical conditions, the objectivity and effectiveness of the use of express raman-fluorescent technologies to assess the mineralization of hard tooth tissues when exposed to various physical and chemical factors in normal conditions, with carious (initial form) and noncarious (wedge-shaped defect, pathological erasability) lesions, are substantiated.

Results of bone grafting using a xenogenic cortical plate BiOTECK
Brailovskaya T.V., Abaev Z.M., Mikhailova A.P., Mamedov K.I., Vedyaeva A.P.
Abstract

BACKGROUND: The fundamental condition that determines the effectiveness of treatment, with immediate and long-term positive results, is the amount of bone tissue in the jaws at the proposed implantation site. Defects in the dentition to a large extent and severe atrophy of the bone tissue of the jaws due to the loss of teeth significantly limit the use of dental implantation. It is reasonable to expand the indications for the use of dental implants in cases of atrophy of the jaw bone tissue in the installation site. This allows the optimization of surgical techniques aimed at increasing the volume of the jaw bone tissue, such as the use of new osteoplastic materials for guided bone regeneration.

AIM: This study aimed to analyze the results of a jawbone graft using a BiOTECK xenogeneic cortical plate.

MATERIALS AND METHODS: The test group consisted of 22 patients (11 men and 11 women) with jawbone atrophy. All patients underwent bone graft surgery using a BiOTECK xenogeneic cortical plate (BiOTECK, Italy).

In the course of the study, all patients with jawbone loss underwent a dynamic clinical and X-ray examination during the following stages: during the dental implant surgery planning stage aimed at determining the volume of the bone tissue available and identifying the associated conditions and diseases (prior to conducting an osteoplastic procedure), prior to dental implant installation (6 months after osteoplastic surgery), and prior to the start of the orthopedic stage of treatment (12 months after osteoplastic surgery).

RESULTS: The cone beam computed tomography data were analyzed and statistically processed to obtain the results. It was revealed that the values of the “bone densitometry” indicator increased 6 months after the bone graft using the BiOTECK xenogeneic cortical plate, and the values of the “densitometric density of jaw bone tissue” indicator increased.

Immediately after bone grafting using the BiOTECK xenogeneic cortical plate, the thickness of the bone tissue of the upper jaw increased by an average of 5.0±0.1 mm and that of the lower jaw increased by an average of 3.9±0.1 mm. In the first stage of the dental implant surgery (6 months after osteoplastic procedure), due to resorption, the thickness of the bone tissue of the alveolar process of the upper jaw decreased by 1.1±0.1 mm and amounted to 6.8±0.1 mm (bone resorption rate: 13.9%), and the thickness of the bone tissue of the alveolar process of the lower jaw decreased by 0.8±0.2 mm and amounted to 6.6±0.3 mm (bone resorption rate: 10.3%).

CONCLUSION: The clinical and X-ray results obtained 1 year after installing dental implants and performing bone graft surgery using the BiOTECK xenogeneic cortical plate indicate a stable volume of marginal bone tissue in the area of alveolar crest reconstruction.

Analysis of the use of classical compression–distraction devices and the latest device for continuous distraction
Kalugina L.S., Topolnitsky O.Z., Fedotov R.N., Beglaryan . ., Afaunova O.A., Minnakhmetova D.R.
Abstract

BACKGROUND: The device used in bone tissue fragment mechanical displacement by expanding the piston between rigidly fixed device legs on the bone fragments is known in classical compression–distraction osteogenesis. In such cases, the control of the displacement is partly left to the patient, since the screw turning must be performed in four sessions per day, and the doctor does not constantly have the opportunity to do it personally, which can lead to uncontrollable results of bone regeneration. To fully control the patient's treatment during distraction, a device that operates continuously and autonomously is required.

AIM: Creation and experimental testing of an automatic distraction device for continuous distraction followed by a study of the obtained bone regenerates and its implementation in practical maxillofacial surgery.

MATERIALS AND METHODS: To fully control the patient’s treatment during the distraction, we developed an unparalleled distraction device based on the principle of continuous bone fragment separation, with a motor in which the piston is activated by an electrochemical reaction. The device performs distraction continuously, around the clock, and autonomously under the control and monitoring of the software and the possibility of remote access. This study included analysis of statistical data on patient treatment in the Russian University of Medicine Department of Pediatric Maxillofacial Surgery Clinic between 2010 and 2021, development and bench testing of devices and electronics, clinical trials of models of devices for continuous distraction at various rates (1, 2, and 3 mm/day) on experimental animals (dogs), X-ray control at the stages of testing, research and analysis of the morphological structure of the resulting bone regenerates, creation of clinical guidelines for the use of a continuous distraction day device, and identification of its advantages compared with the classic fractional compression–distraction device.

RESULTS: Statistical data analysis revealed that 362 patients were treated with distraction devices. This is a relatively high percentage in relation to all patients in the clinic. Studies of the morphological structure of regenerates obtained by continuous distraction with our latest device revealed a higher rate and control of regenerates, good quality characteristics, and histomorphological maturity, most pronounced in regenerates obtained by continuous distraction at a rate of 2 mm/day.

CONCLUSION: The need for treatment with distraction osteogenesis in the department’s clinic is rather high; hence, this process should be controlled to improve treatment quality and speed. Our automatic distraction device designed for continuous distraction may be implemented and applied in practical medicine at an appropriate rate of 2 mm/day.

Evaluation of clinical effectiveness of hygiene products for the care of facial prostheses
Igumnov A.I., Apresyan S.V., Stepanov A.G., Kharazyan A.E., Grigoryants L.S., Suonio V.K., Zrazhevskaya A.P.
Abstract

BACKGROUND: Because of the porous structure of the structural material used in the production of facial prostheses, without careful hygienic care, microbial biofilms may form on the material surface, its color and shape may change, and premature aging may occur. Means for the hygienic care of facial prostheses and research to confirm their clinical effectiveness are crucial in dentistry.

AIM: To increase the effectiveness of the hygienic treatment of facial epitheses.

METHODS: A single-center randomized study was conducted to assess the clinical effectiveness of hygiene products for the care of facial prostheses. This study involved patients with exenteration of the eye socket, previously prosthetic with adhesive fixation epitheses. The patients were divided into four groups and received different hygienic care methods. Furthermore, during the use of the prosthesis for 14 days and 1 and 3 months, the tissues of the prosthetic bed and hygienic condition of the prosthesis were evaluated, and the quality of life of patients was determined.

RESULTS: According to the results of measuring the area of inflammation of tissues of the prosthetic bed of the eye socket at different terms, positive dynamics were found in the groups that used the proposed hygiene products.

CONCLUSION: A strong positive correlation (r >0.9) of the average values of the quality of life index, area of inflammation, and hygiene index of the orbital epitheses in the study groups at the appropriate time indicates improved quality of life of patients who used the proposed hygiene products by reducing the amount of bacterial plaque on the surface of the epithesis and, in turn, reducing the area of inflammatory reactions and increasing comfort in wearing the prosthesis.

Elastomeric impression materials used in modern orthopedic dentistry
Bordina G.E., Lopina N.P., Andreev A.A.
Abstract

This article presents a review of elastomeric impression materials currently used in orthopedic dentistry. The elastomer group is divided into silicone, polyester, and thiocol (polysulfide) materials. Silicone impression materials are widely used in orthopedic dentistry. Their structural basis is polymethylsiloxane with active terminal hydroxyl groups. Polyester materials consist of the main and catalyst components (pastes). The main component contains a polymer with imine groups, fillers, and plasticizers. Sulfonic acid ester is present in the catalyst paste. When these two components are mixed, ionic (cationic) polymerization occurs. Polysulfide materials are produced as base and catalyst pastes. The structural unit of the main paste is polysulfide or mercaptan rubber, and the catalyst paste acts as an oxidizer. Lead dioxide is often used as an oxidizer. The resulting polymer does not have a stereoregular structure, which causes its stickiness. It is technologically challenging to obtain a polymer with a stereoregular structure.

When theoretically comparing the listed types of elastomeric impression materials, according to their properties, chemical composition, advantages, and disadvantages, polyester and polysulfide impression materials can be distinguished as more advanced. Silicone materials have disadvantages; however, they are often used for domestic dentistry owing to the presence of domestic manufacturers and relatively low cost.

Effect of antitumor therapy on microflora and oral mucosa in patients with malignant neoplasms
Pashchenko N.A., Kazakov V.F., Zavyalov A.A., Olesova V.N., Tyryshkin A.I.
Abstract

The present article investigates the relationship between the microbiota of the oral cavity and oral mucositis induced by systemic antitumor therapy in patients with malignant neoplasms. This article highlights modern ideas about the composition of the normal microbiota of the oral cavity and its changes during chemotherapeutic treatment.

It has been shown that the normal oral microbiota includes representatives of such genera as Actinomyces, Corynebacterium, Fusobacterium, Leptotrichia, Neisseria, Prevotella, Streptococcus, and Veillonella. Moreover, it is emphasized that despite the existence of modern molecular genetic techniques and development of an oral microbiota database, determining the role of individual taxonomic units in oral homeostasis remains challenging.

Existing studies of changes in the qualitative and quantitative composition of oral microflora against the background of drug antitumor therapy have demonstrated that treatment is associated with significant changes in the microbiological landscape of the oral cavity. An increase was noted in the number of Gram-negative anaerobic opportunistic flora and a decrease in the representation of protective commensal flora. It has been demonstrated that the components of a bacterial cell can modulate the local reactions of a macroorganism through a system of Toll-like receptors while acting in different directions.

Several unresolved fundamental issues related to the role of oral microbiota in the pathogenesis of oral mucositis are highlighted.

Overview of clinical and laboratory evaluation results of the effectiveness of digital methods for knowledge-based fabrication of complete removable acrylic dentures
Verkhovskiy A.E., Apresyan S.V., Stepanov A.G.
Abstract

This article provides an overview of the conceptual studies of modern digital technologies for the fabrication of complete removable acrylic dentures. Analysis of data of subtractive and additive methods of digital manufacturing shows the advantages of digital CAD/CAM methods over traditional methods. The use of known prepolymerized acrylic blocks in the subtractive milling method has enabled achieving high physical and mechanical properties, optimal spatial accuracy, and minimal thickness of the fabricated dentures. Moreover, residual monomer volume reduction in solid polymer blocks has allowed the high biological inertness and safety of the fabricated structures for prosthetic bed tissues and the patient’s body. Layer-by-layer printing of removable dentures by fused polymer deposition modeling technology results in high spatial accuracy of constructing structures of any degree of complexity and reduced total production time of removable dentures.

Despite the intensity of implementation of digital CAD/CAM technologies in the practice of complete removable denture manufacturing, the search for alternative methods of modernization of the known traditional means and methods continues. However, we believe that automation and digitalization of the clinical and laboratory manufacturing of complete removable acrylic dentures has clear prospects for the total replacement of compression pressing and hot polymerization techniques of acrylates. In summary, the potential prospect in the future is a global reassessment of traditional concepts for the fabrication of complete removable dentures, considering the formation of an innovative digital CAD/CAM philosophy and the introduction of computer intelligent systems.

Current views on treatment of halitosis: foreign practice
Donskaya O.S., Berdnikova E.I., Osipova V.A., Markvashev T.M.
Abstract

Traditional halitosis treatment involves reducing microbial contamination through chemical and/or mechanical action; however, these methods are ineffective in the long-term.

According to recent systematic reviews, there is no scientific evidence of the effectiveness of halitosis treatments, and even when reports indicate a positive effect, it is temporary. To increase the number of studies being compared, analysis of the results of randomized controlled trials (RCTs) should be performed considering already published data. Therefore, a review of recent RCTs is required for conducting and planning further scientific research on halitosis treatment.

Purpose of the investigation — to study the effectiveness of oral halitosis treatment based on materials from foreign publications from 2019 to 2023.

This article provides a descriptive review of foreign scientific publications on modern methods of treating oral halitosis. A search for full-text articles was conducted in the electronic databases PubMed and Google Scholar for 2019–2023. The most relevant articles that met the selection criteria were selected and included in this review: 31 publications on oral halitosis treatment: 3 Cochrane reviews of RCTs; 14 literature reviews, including meta-analyses; 12 RCTs and clinical studies; and 2 experimental studies.

In foreign studies, the use of probiotics and photodynamic therapy and their combination with standard treatment methods are most widely presented; RCTs have established their effectiveness, especially when used together with traditional methods of mechanical tongue cleaning. To prevent halitosis, it appears relevant to use materials with antibacterial properties in prosthetics, particularly the modification of polymethyl methacrylate with silver and graphene nanoparticles.

However, against the backdrop of positive results obtained in individual reviews, the conclusions of systematic reviews are contradictory. There is no evidence of the long-term effectiveness of the proposed treatment methods, and there is a weak evidence base for studies, which makes it challenging to use them in the practical work of dentists. In this regard, new RCTs with a longer observation period and considering published data are required.

Case reports

Two-stage surgical plastic surgery of the lost interdental papilla in class III recession according to Tarnow and Nordland
Babanina A.A., Runova G.S., Daurova F.Y., Tomaeva D.I.
Abstract

This report presents a clinical case of elimination of the recession of the interdental papilla of class III according to Tarnow and Nordland with the help of mucogingival plastic surgery in two stages. Before the surgical intervention, orthopedic structures and braces were installed on teeth 1.1 and 2.1 to eliminate the diastema between the teeth and bring the roots of the teeth closer together 1.1, 2.1. The first surgical stage of eliminating the recession of the interdental papilla was the use of a coronal-displaced flap using a free gingival graft to increase soft tissues in the area of the lost interdental papilla. The second surgery for eliminating the recession of the interdental papilla and recreating its anatomical shape was tunnel plasty of the interdental gum using a free gingival transplant.

In this clinical case, the patient was fixed with an orthopedic structure with a space under the interdental papilla (5 mm), which is a criterion for complete restoration of the shape and volume of the interdental papilla. The full restoration of the volume, height, and anatomical contour of the interdental papilla is achieved thanks to the interdisciplinary work of dentists — periodontists, therapists, orthopedists, and orthodontists. A stable result was noted 1 year postoperatively.
