Afanasyeva, L. A. Devyatchenko","doi":"10.33925/1683-3031-2024-762","DOIUrl":"https://doi.org/10.33925/1683-3031-2024-762","url":null,"abstract":"Relevance. Myofascial pain syndrome (MPS) often progresses to a chronic form that is challenging to treat with established methods. This issue is well known to dentists and frequently leads to frustration despite significant efforts to advance knowledge in the fields of etiopathogenesis, diagnosis, and therapy. Most treatment protocols focus on normalizing physiological parameters, such as restoring masticatory function, achieving stable occlusal relationships, alleviating pain, and enhancing the psychological well-being of these patients. Therefore, the need for non-invasive diagnostics to assess functional activity and monitor the condition of masticatory muscles during treatment is crucial. This study aims to address this need.Materials and methods. The examination and treatment of 64 patients with myofascial pain syndrome were conducted in two stages—clinical and electromyographic. During the clinical examination, tenderness of the masticatory muscles during palpation and the degree of mouth opening were assessed. The electromyographic research was also conducted in two stages. The first stage assessed the average amplitude and total biopotential of the masticatory and temporal muscles on both the right and left sides. The second stage evaluated the symmetry index of the masticatory muscles, as well as torsion and masseter indices. The first group received conventional treatment combined with laser therapy, while the second group received ozone therapy and kinesiology taping in addition to the conventional therapy.Results. In the short-term observations over 14 days, both groups achieved positive results. However, patients undergoing ozone therapy and kinesiology taping showed statistically significant improvements in their parameters by the third day of observation compared to their baseline values.Conclusion. For diagnosing this pathology, it is advisable to incorporate electromyography into the examination protocol to allow non-invasive evaluation of the functional activity of the masticatory muscles. For treating myofascial pain syndrome, minimally invasive methods with anti-inflammatory, analgesic, and muscle relaxant effects are recommended. While all treatment methods yielded favorable results, ozone therapy combined with kinesiology taping effectively eliminated both subjective and objective symptoms in this patient category.","PeriodicalId":196403,"journal":{"name":"Pediatric dentistry and dental prophylaxis","volume":"56 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141682318","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Palatoplasty is a technically demanding reconstructive surgery for congenital full-thickness defects of the palate, with more than 20% of cases reporting postoperative complications. The primary cause of these complications is chronic oral inflammation. To mitigate inflammatory reactions, medications with antibacterial, bactericidal, and antiseptic properties are employed. Given the age-specific characteristics of children and the presence of full-thickness palate defects, it is essential to administer anti-inflammatory medications in an adapted, prolonged, and safe form. Consequently, we have developed a prolonged-release phytocomplex in the form of lozenges.Purpose. To evaluate the effectiveness of a prolonged-release phytocomplex in preventing postoperative complications in children following palatoplasty.Materials and methods. This study presents clinical and laboratory examination data from 90 children aged 2.5 to 5 years with cleft palate who underwent palatoplasty, and 45 healthy children aged 3 to 8 years. The study involved measuring the levels of secretory immunoglobulin IgA in the oral fluid using the 'IgA Secretory ELISA-BEST' reagent kit, cytokines (interleukins-2, 4, 6), and gamma-interferon through enzyme immunoassay with kits from 'Vector Best' (Russia), and lysozyme using the Lysozyme-96 kit.Results. It was observed that following the use of the prolonged-release phytocomplex, the levels of sIgA, lysozyme, and interleukins-2, 4, and 6 in the oral fluid of the children were significantly elevated compared to the control group. Additionally, the gamma-interferon levels returned to normal. Conclusion. The findings of this study demonstrate the positive antimicrobial, anti-inflammatory, and woundhealing effects of the developed prolonged-release phytocomplex in the form of lozenges.","PeriodicalId":196403,"journal":{"name":"Pediatric dentistry and dental prophylaxis","volume":"23 19","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141685546","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Distal occlusion is one of the most frequently encountered anomalies in orthodontic practice among patients with both temporary and permanent dentitions. When selecting a treatment method for this anomaly, it is crucial to consider several significant factors, including the craniofacial stage of skeletal maturity and the type of jaw growth. Special attention should be given to the method of treating patients with incomplete skeletal growth using a twin-block appliance, followed by continued orthodontic treatment with fixed orthodontic appliances (braces).Clinical case description. This article presents a clinical case of treating a patient with distal occlusion in the peripubertal stage of skeletal growth, which is the most optimal for the initial stage of orthodontic treatment.Conclusion.

One of the challenges in endodontic treatment is preventing the presence or introduction of pathogenic flora into the root canal. Modern treatment protocols aim to maintain aseptic conditions throughout all stages of treatment. Before the final sealing of the root canal, it is dried using endodontic paper points (absorbers). Using previously opened packages of absorbers can pose a risk of contamination by environmental microorganisms.Purpose. This study aims to evaluate the effectiveness of microbial decontamination of endodontic absorbent paper points using various ultraviolet (UV) irradiation treatments.Materials and methods. The study used standard endodontic absorbent paper points, manufactured by compressing paper into cone shapes of various sizes, designed to remove residual moisture from the root canal. The experiment was conducted at the subdivisions of KubSMU of the Ministry of Health of Russia. During the study, absorbers were placed in a bactericidal UV chamber for 1, 3, and 7 days according to the study design. Subsequently, the paper points were immersed in nutrient media and incubated. Results were recorded daily by visually checking for signs of microbial growth (turbidity, sediment, flakes, and other changes in the media). Decontamination was considered complete in the absence of microbial growth in all test tubes. The comparison of the number of positive results was performed using the analysis of four-field contingency tables (comparison of percentage shares in two groups) using the Chi-square test with Yates' correction for independent groups and the McNemar test for dependent groups using Statistica 8.0 software (StatSoft, USA).Results. Analysis of the results from culturing the test samples in nutrient media confirms the safe use of endodontic absorbent paper points immediately after opening the commercial package. In the model used, microbial growth was observed in 22.2% of cases on various media. No positive results for bacterial or fungal contamination were found in samples after treatment. Comparison of the proportion of positive contamination results showed a statistically significant difference according to the McNemar test (p = 0.027). Similarly, a statistically significant difference in the proportions of positive contamination results was observed when comparing with the control group using the Chi-square test with Yates' correction for independent samples (p = 0.009).Conclusion. The study demonstrated that using a UV chamber for storing and decontaminating endodontic absorbent paper points is effective after just one day, significantly reducing the risk of microbial complications in endodontic treatment.","PeriodicalId":196403,"journal":{"name":"Pediatric dentistry and dental prophylaxis","volume":"68 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141694561","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To identify the nature of the relationship between various forms of orthodontic and speech disorders in children, we conducted a comprehensive clinical dental examination of 80 children aged 4-6 years in a preschool educational institution, where children with speech disorders receive speech therapy assistance.Results. Maxillofacial deformities appeared to be in 56.25% of children with some speech sound disorder. Children with identified speech sound disorders combined with dentofacial deformities showed not only skeletal but also soft tissue defects: shifted midline (86.67 ± 0.10%), distal occlusion (42.22 ± 0.30%), deep overbite (46.68%), as well as tongue and upper lip ties in 51.10% and 22.20% of cases, respectively.
