One of the clinical peculiarities is the fact that TMD is often associated with various changes in mechanical pain sensitivity (MPS) at the level of the structures of the stomatognathic system (temporomandibular joint, masticatory muscles), which has the impact of increasing the difficulties of diagnosing this problem for the clinicians. Objective of the study: to evaluate options for clinical investigation of the expression and spatial distribution of mechanical pain sensitivity (MPS) in temporomandibular disorders. Material and methods: We performed the analysis of the variation in the expression of mechanical pain sensitivity (MPS) based on the data obtained by algometry (thresholds of sensitivity/tolerance to pressure) collected in 55 patients. The investigation was carried out in the projection of acupuncture points ST6 (masseter muscle), ST7 (temporomandibular joint). Data collection was carried out in 2 states (relative rest conditions, operational stress modeling). The investigation of the spatial distribution of mechanical pain sensitivity (MPS) was carried out through pain maps at the level of the masseter muscle (30 patients with temporomandibular disorders and 30 asymptomatic people - control group). Results: In the study, it was identified that the expression of mechanical pain sensitivity (MPS) varies according to the test conditions (relative rest/modeled operational stress), being attested statistically significant reductions at the masseter muscle level (tolerance threshold and sensitivity/tolerance threshold ratio) under stress conditions. This state reveals a hypoalgesia occurring after the stressful event, which reflects the complexity of the mechanisms involved in the pathogenesis and evolution of TMD. The observed spatial distribution of mechanical pain sensitivity (MPS) revealed the importance of using complex synthetic indices, which allow the processing of raw data (sensitivity/tolerance thresholds), including the reflection at the level of MPS heterogeneity/homogeneity. Conclusions: Investigating the particularities of mechanical pain sensitivity at the level of the stomatognathic structure, especially masticatory muscles in temporomandibular disorders, which represent a reliable interdisciplinary approach, which requires investigation in multiple standardized conditions (relative comfort/operational stress modeling), with the evaluation of the sensitivity distribution (pain maps). The integral view of TMD through the prism of MPS aspects provides new clinical evaluation criteria (expression intensity, spatial distribution, heterogeneity).","PeriodicalId":122574,"journal":{"name":"Journal of Stomatological Medicine","volume":"21 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141407593","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}

Bilateral terminal partial edentulism in the maxilla represents a complex and challenging clinical condition in dental practice, requiring a meticulous and personalized approach for the adequate restoration of functionality and morphology of the stomatognathic system. Within this pathology, acrylic removable partial dentures are emerging as a therapeutic alternative of prime importance, providing an adaptable and effective solution for patients affected by these specific dental deficiencies. The objective of this study is to provide a detailed analysis of the clinical picture associated with bilateral terminal partial edentulism in the maxilla, focusing on relevant anatomical, functional and aesthetic aspects. Also, the assessment of the impact of the treatment performed with acrylic removable partial dentures on the quality of life and the level of satisfaction of the patients participating in the research will be studied. Materials and Methods. For this study, 20 patients aged between 45 and 60 years with a clinical presentation of bilateral terminal edentulism in the maxilla, treated with removable acrylic partial dentures were selected. The examination and evaluation of the patients was done over a period of eight months at the Department of Dental Propaedeutics „Pavel Godoroja”, USMF, „Nicolae Testemițanu”. Oral health-related quality of life was assessed with the Oral Health Impact Profile-14 questionnaire. Data were analyzed using descriptive and multivariate analyzes at a significance level of p < .05. Results. Following clinical examinations, it was determined that removable acrylic partial dentures are favorable because the prosthetic field provides maintenance and stability. The biological adaptation of removable acrylic prostheses is the process by which these intraoral devices are tolerated and accepted by the oral tissues and the patient’s body as a whole. This fit is essential for the patient’s long-term comfort, functionality and oral health. The biological adaptation of removable acrylic prostheses has been recognized as an essential element for ensuring comfort, functionality and long-term oral health in selected patients. This process was essential for oral tissue tolerance and avoiding potential complications such as gingival lesions or discomfort. Conclusion. The results obtained from the study confirmed that the biological adaptation of acrylic removable partial dentures is an essential factor in ensuring long-term comfort, functionality, and oral health. In the perspective of dental practice, these findings support the need for a personalized and careful approach in treating bilateral terminal partial edentulism in the maxilla, with the ultimate goal of optimizing therapeutic outcomes and providing patients with efficient, comfortable, and aesthetic solutions.","PeriodicalId":122574,"journal":{"name":"Journal of Stomatological Medicine","volume":"64 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141404011","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}

An effective management is an art, which consists in the mastery of the manager to apply the scientific elements and to value managerial skills and qualities with a creative and innovative effect. Successful people with the ability to turn their desires into good results are those who have learned the ability to motivate themselves. Objective of the study. Determination of individual professional capacities and personal psychology with the purpose of initiation of general motivation measures, applicable in the provision of dental services to the population. Material and Methods. The study of the motivation of employees in dental institutions was carried out from the point of view of the position occupied in the management hierarchy: the first category - are those who coordinate the work of the executive staff - head of department, head of office, managers, etc.; second category - head of department, association, directors of medical institutions, who organize, plan, coordinate and control the activity of employees; the third category – managers with strategic capabilities in the management of medical services. The examination of the motivation possibilities highlighted two models: 1. Material motivation – awarding an annual salary of merit, quarterly awards, incentives, etc.; 2. Non-material motivation – the ambition of the staff to achieve certain performances, inducing the satisfaction of teamwork, obtaining personal professional satisfaction, etc. Results. The analysis of the obtained results demonstrates the fact that the hierarchy has a significant role in the relations between employees in dental institutions. The boss-subordinate relationship is one of the most important and to the greatest extent contributes to the achievement of the institution’s objectives, in ensuring and maintaining performance at the individual and collective level. It is important to note that the result of motivation is directly related to employee satisfaction. The most important aspects of satisfaction highlighted can be: independence of thought and action, personal develop ment, participation in setting goals and objectives, etc. Demotivation is a process encountered in medical institutions and considered as one of the main reasons why employees do not perform their tasks. Thus, in the managerial activity, it is rational to apply the following types of motivation - economic, professional and psychological, offering the possibility of achieving, through the unification of efforts, some performances that contribute to the improvement of the dental services provided to the population. Conclusions. Staff motivation studied within public institutions is a very interesting topic, because the motivation tools are limited and the salary system is rigid and fixed.","PeriodicalId":122574,"journal":{"name":"Journal of Stomatological Medicine","volume":"727 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141401163","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}

The interproximal relationship is defined as the relationship between the neighboring teeth within the same dental arch or the relationship that exists between the mesial surface of one tooth and the distal surface of the adjacent tooth. As a component of the interproximal ensemble, interdental contact is the anatomofunctional unit that contributes to the stabilization of teeth, maintains the integrity of the dental arch, protects the papilla and prevents food impaction. Objective of the study. The radiographic assessment of proximal morphology, marginal adaptation of restorations, and the positioning of obtained interdental contact in lateral teeth. Material and methods. The study included 80 digital bitewing radiographs in which proximal restorations on lateral teeth were evaluated for morphology by assessing the presence of a concave, convex, or straight surface; cervical adaptation by identifying a harmonious transition between the tooth and the restoration or a marginal step; interdental contact by determining its position in the cervico-occlusal direction. Results. Out of the 80 proximal restorations analyzed in lateral teeth, 34 were on mesial surfaces and 46 on distal surfaces. 58 restorations exhibited a convex emergence profile, 2 - concave, and 20 - straight. 53 restorations showed a harmonious cervical adaptation, while 27 revealed the presence of a marginal step, ranging from a minimum of 0.1 mm to a maximum of 0.9 mm. 66 restorations demonstrated proximal contact with the adjacent tooth, while 14 showed a lack of interdental contact. Among the restorations with proximal contact, 21 corresponded to anatomically correct positioning in the cervico-occlusal direction, and 45 did not correspond, being displaced occlusally.

One of the current challenges in contemporary clinical medicine is infectious diseases. According to WHO data, herpes simplex virus (HSV) infection ranks second among human viral illnesses. Herpes simplex virus, an obligate intracellular parasite, belongs to the alpha subfamily of Herpesviridae. The virus cannot replicate outside living cells. There are two types of HSV: HSV-1, which is involved in oral mucosal conditions, and HSV-2, the causative agent of genital herpes and occasionally oral herpes. Literature data suggests that almost 90% of the population is infected and carriers of the virus. Clinical manifestations differentiate between primary (acute) herpetic gingivostomatitis and secondary (recurrent) herpetic stomatitis. Objective of the study: To examine the cause of herpetic infection in the oral cavity, clinical symptoms of the condition depending on the affected region of the oral mucosa, and determine the correct treatment approach. Materials and Methods. Nineteen patients with manifestations of chronic herpetic stomatitis in the oral cavity sought treatment at Dental Clinic of the State University of Medicine and Pharmacy „N. Testemițanu”. Subjective complaints included pain upon touching the affected region and difficulty in food consumption. From the medical history, all patients reported the frequent recurrence of chronic herpes elements, ranging from 1-2 times per year. The general condition of the patients was satisfactory without fever. Clinically, mild congestion and edema of the vermillion border and surrounding skin were observed, followed by vesicular eruption in clusters. Ulcerations appearing after vesicle rupture formed crusts within the next 2 days. Oral lesions were located on the attached gingiva, hard palate, and lateral surfaces of the tongue. They started as vesicles that rapidly ruptured, resulting in erythematous ulcers with a tendency to coalesce. Oral hygiene in patients was unsatisfactory (II OHI-S 3.0 and above). There was an abundance of soft and hard deposits, moderately hyperemic and edematous free gingival margin, with preserved integrity of the dentogingival junction. Oral sanitation was necessary in 11 clinical cases. All patients underwent both general and local treatment. General treatment included antiviral drugs, desensitizing agents, immunomodulatory therapy, and vitamin C. Local treatment aimed at topical applications of analgesics, proteolytic enzymes, antivirals (aerosol, ointment), and immunomodulatory preparations. At the end of the treatment, all patients underwent professional dental hygiene. Results and Conclusions. The applied treatment approaches were classified as etiotropic, pathogenetic, and symptomatic. Etiotropic treatment was based on the use of specific antiviral drugs targeting HSV, medication inhibiting DNA and RNA replication in HSV-infected cells. Pathogenetic treatment involved the use of immunomodulators to normalize the immune system function.

The clinical concept that would argue that the activity of the lateral pterygoid muscle, being disturbed, would play an important role as an etiological factor in temporomandibular joint dysfunctions is still widely accepted, being also a decisive factor in the correct choice of the treatment plan. However, because of the fact that very few research and clear evidence were conducted and presented to support completely that concept, it continues to remain a very controversial one. Materials and methods. For this literature review were considered and studied scientific articles published between 2000 and 2023, in the following electronic databases: PubMed, MEDLINE, Google Scholar, BIR Publications, ScienceDirect. Research methods – analysis, synthesis, systematization and description. Results. Patients presenting temporomandibular joint dysfunction complain about pain in the temporomandibular joint or/and in masticatory muscles, limitation and sounds during mandibular activity. Temporomandibular dysfunction is a non-specific collective term, used to describe a heterogeneous group of pathological conditions located in the territory of the stomatognathic system. These are considered musculoskeletal conditions that cause pain while performing the function (mastication, speech, swallowing), with increased sensitivity in the masticatory muscles and/ or the temporomandibular joint, with possible limitations of the range of motion, the appearance of joint noises and otological symptoms. One of the theories claims that in temporomandibular dysfunction, the lateral pterygoid muscle becomes hyperactive, hypoactive or that there is a lack of coordination between the superior and inferior branches of the muscle, or that there is a disturbance during the performance of the role of the muscle to control and stabilize the temporomandibular joint. However, the in-depth study of the specialized literature indicates that no scientific evidence is yet available that the function of the lateral pterygoid muscles in temporomandibular dysfunction is somehow disturbed. Moreover, the muscle’s role during the execution of its normal function has also been questioned and remains a matter of controversy. Conclusions. The lateral pterygoid muscle obviously plays an important role in the development of temporomandibular dysfunction through the prism of its anatomical and functional particularities, referring to the superior fascicle responsible for the correct anatomical maintenance of the articular disc during function.","PeriodicalId":122574,"journal":{"name":"Journal of Stomatological Medicine","volume":"1991 7","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141400914","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}

Objective of the study. The aim of this study is to analyze contemporary approaches and strategies in formation of interdental contact points in Class II lesions, according to the principles set by G.V. Black. Materials and Methods: A prospective study of 15 patients at the “DENTLAND” SRL Clinic, 9 males and 6 females, aged between 20 and 45, average age of ±38 years, using exclusion criteria. Diagnosis was established based on clinical and paraclinical examinations. Paraclinical examination: transillumination, retroalveolar radiography and orthopantomography had a crucial role in determining the final diagnosis. Direct restoration methods with light-cured composite materials were employed in various obturation techniques: centripetal obturation technique and alternative oblique layering technique, along with matrix systems. Results: The research analysis revealed 15 cases, with 8 patients having caries that undermined and interrupted the marginal ridge (54%), and 7 patients with caries that undermined but did not interrupt the marginal ridge (46%). For the formation of the contact point, the Palodent Plus matrix system was used in 10 patients (67%), while the Palodent Generation I matrix system was used in 5 patients (33%). Out of the total 15 restorations, when dental floss was passed over the recently restored approximal surface, it was observed to be intact in 13 patients, while in 2 patients, dental floss was dissociated. The cause of this complication was the inability to individualize and adjust the Palodent Generation I system compared to the Palodent Plus system.

The association of systemic diseases with the hypoxia syndrome during the child’s growth periods increases the risk of pathological changes in the tissues, characterized by the increase in the activity of anaerobic glycolysis processes with the intensification of lactic acid formation. Similar phenomena also occur in the dental tissues in the process of development, the cells of the salivary glands, subsequently generating a cariogenic situation. Although several authors have reported the increase in dental caries (DC) and cases of enamel hypomineralization in children with central nervous system (CNS) diseases caused by perinatal hypoxia, the role of phosphocalcium metabolism disorders, especially of bioenergetic processes, in triggering of the carious process have not been sufficiently studied, and the establishment of a possible interdependence will allow the development of new strategies for the prevention and treatment of dental pathology. The objective of the study was to study the relationship between dental caries and markers of phosphocalcium and bone metabolism in children with severe diseases of the central nervous system caused by perinatal hypoxia. Materials and methods. In order to achieve the set objectives, a case-control clinical study was carried out on a sample of 1272 children. Dental caries preva lence indices (PI) and carious experience indices were evaluated in 636 children with CNS diseases caused by perinatal hypoxia (L1), compared to 636 conventionally healthy children (L0). To highlight the impact of metabolic disorders on DC susceptibility of children with severe CNS diseases, biochemical markers of redox processes, bone metabolism, phosphocalcium and anaerobic glycolysis products were studied in blood serum and oral fluid (OF). Results. In children with severe CNS diseases, increased values of PI indices (79.40±0.84%, p<0.001) and caries experience (4.03±0.088, p<0.001) were appreciated, compared to conventionally healthy children. The chronic disorder of redox processes, phosphocalcium metabolism at the macroorganism and local level was detected, which significantly influences the degree of CD damage in children with severe CNS pathology, confirmed by: increased lactate level and lactate dehydrogenase activity, reduced activity of heat-labile alkaline phosphatase in the serum blood and in OF, as well as the statistically significant increase in tartrate-resistant acid phosphatase activity in the blood serum, the statistically significant decrease, below the normal limits, in the level of Ca, Mg and vitamin D3 in the blood serum, as well as the significant reduction of the Ca/Pi ratio in the FO.

The increase in the frequency of transverse malocclusions, determined based on the frequent presentation of patients, has led to a need to identify predisposing factors. Transverse malocclusion is caused by: the discordant development of the two jaws, midline discrepancies of dental arches in asymmetric lateral areas, isolated dental malpositions, guidance slopes, lateral movements, and nasal breathing disorders. Depending on its duration, mouth breathing can lead to numerous functional, structural, postural, and behavioral changes, including at the level of the maxillary system, which is closely structurally and functionally linked to the upper respiratory pathways. Therefore, addressing these issues will allow for a deeper understanding of the etiology of transverse malocclusions, the influence of nasal breathing disorders, and the determination of optimal terms for orthodontic treatment, its types, as well as the possibility of preventing relapses. Objective of the study. Developing new diagnostic criteria for patients with transverse malocclusion through studying the effects of nasal breathing dysfunctions. Study goals. Identification and analysis of the frequency of nasal respiratory disorders among patients with transverse malocclusions; Investigating clinical and anthropometric changes in the stomatognathic system in cases of transverse malocclusions through transnasal airway passage analysis; Comparing patterns of transverse malocclusion manifestation based on clinical, biometric, cephalometric parameters, and nasal respiratory volume.Methods and Materials. The study was conducted based on the analysis of a group of 201 patients aged between 7 and 18 years, including 120 girls (59.7%) and 81 boys (40.3%) with transverse malocclusions. The patients were divided into two study groups, depending on the type of malocclusion they presented. Consequently, they were assigned to T0 and T1. The T0 group consisted of 92 patients (45.8%) with transverse malocclusions without nasal breathing disorders, and the T1 group consisted of 109 patients (54.2%) with transverse malocclusions associated with nasal breathing disorders. Among the 109 patients, there were cases of chronic hypertrophic rhinitis - 10 (5.0%), predominantly determined in patients with nasal septum deviation - 57 (28.4%), followed by chronic and recurrent sinusitis - 22 (10.9%), and chronic adenoiditis - 20 (10.0%). The diagnosis was established based on clinical examination, paraclinical methods such as orthopantomography and lateral and posteroanterior cephalometric radiography, using Downs, Tweed-Merifeld, and Ricketts methods. For patients in the T1 group, the diagnosis was complemented with a medical history that revealed complaints related to the location of the pathological process, and nasal permeability assessment was performed using the ATMOS PC 2000 rhinomanometer (Germany).

Elaborated classifications on the subject of the study, computer scheme to study the interdental contact points by the static biomechanical method. Actuality: The problem of the diagnosis, treatment and prevention of caries of high-quality proximal surfaces is one of the most important in the world. The defeat of this area is diagnosed in 73.8% of all carious defects (Лидман Г.Ю. и соавт., 2009). In Russia, proximal caries of posterior teeth reach 40% (Арнаутов Б. П., 2016). In the specialized literature, the morphology and biomechanics of proximal interdental contacts are sufficiently elucidated.Objective of the study: To study the microscopic characteristics of the morphology, topography and biomechanics of the interdental contact points of permanent teeth. Material and methods: 120 teeth extracted for medical reasons were prepared according to the generally accepted technique without making thin sections and studied. The microarchitectonics of the occlusal and proximal interdental contact areas was studied using a portable digital microscope “Levenhuk DTX 500 Mobi” (Levenhuk, USA). Interdental contact topography was studied on study models and on student volunteers aged 22 to 26 years. The microrelief of the proximal contact areas in all teeth has common features. They often consist of several, on average 2-3, different zones and configurations, thus resembling articular surfaces. The maxillary front teeth are characterized by the presence of two longitudinal areas separated by a thin enamel ridge. The biomechanical features of the interdental contacts of the lateral teeth were studied with the help of the “parallelogram of force” computerized scheme. Conclusions: 1. New data were obtained on the morphology of interdental contact points for all groups of teeth, their topography, microarchitectonics of contact areas and biomechanics characteristics). 2.
