Methods of Validation of the Paraclinic Diagnosis – Rx by Image Processing

The radiological examination is part of complementary para-clinic examinations currently used in dental practice. This work present a method of improving the quality of X-ray dental images obtained through the classical techniques by specific image processing. The method consists of contours detection and bone density evaluation for interest areas. It is an easy approach for any type of retro-dental Rx investigation suggesting clinical decision

THE IMPORTANCE OF ARTICULAR MOBILITY TESTING DURING TMJ CLINICAL EXAMINATION TECHNIQUE

Introduction The examination of the temporomandibular joint represents a primary phase in the clinical evaluation of any patient, weighing extremely heavy especially when diagnosing the dysfunctional syndrome. There are 3 directions of examination, but the last one in almost unknown, used neither, although is so important for complex oral rehabilitation. Goal So, we want to describe this method, to make aware all practitioners of its importance. During objective examination of TMJ, we must to do inspection, palpation, auscultation and also to explore the vertical mobility (open-close movements) or the horizontal mobility (propulsory, retropulsory, laterality, latero-pulsory movements). Knowing normal values of measured amplitudes, we can recognize TMJ pathology. Conclusion: Clinical examination of TMJ must be done correctly and following all steps, in this manner the practitioner will be able to detect all evident or less evident signs and to formulate the most precise diagnosis

Correlations Between The Periodontal Modifications And Lipid Peroxidation In Periodontal Disease Patients

The purpose of the study Our study was centred on the comparative research of enzymatic and non-enzymatic oxidative status mediators in the crevicular fluid on chronic and aggressive periodontitis patients, compared to periodontal healthy subjects. Materials and methods The study was conducted on 42 patients. They were divided in 3 study groups: chronic periodontitis subjects, aggressive periodontitis patients and periodontal healthy subjects. On marginal periodontitis patients, associated or not with systemic diseases, we initially collected gingival crevicular fluid and saliva samples and we evaluated the following enzymatic stress markers for all the three groups of subjects: superoxide dismutase, glutathione peroxidase, malondialdehyde, using the gingival crevicular fluid (GCF) as biologic material. Results The statistical analysis for the malondialdehyde in the control group, aggressive periodontitis group and chronic periodontitis group shows significant differences between the groups. SOD values in the gingival crevicular fluid were low in the periodontitis groups compared to the control group. Despite the strong correlation between the glutathione peroxidase values in the three groups, we did not observe any significant differences between the GPx values in the aggressive periodontitis, chronic periodontitis and control groups. Conclusions The present study revealed significant statistic differences between most of the oxidative stress parameters analysed in the GCF, especially in the aggressive periodontitis group, less in the chronic periodontitis group compared to the control group

Neuromuscular Disabilities in Patients Diagnosed with Algo-Dysfunctional Syndrome

Introduction: Stomatognathic system dysfunctional syndrome is triggered by cumulative intra- and over-systemic factors, morphological and functional asymmetries favouring the occurance of the syndrome. Aim of the study: The present study intended to evaluate the relationship between the general manifestations of Parkinson’s disease, hemifacial spasm, and the dysfunctional syndrome of stomatognathic system. Material and methods: The study comprised 2 groups of patients, 33 diagnosed with Parkinson’s disease, and 10 patients with hemispasm, that were evaluated not only by paraclinical parameters, but also by the clinical neurological and dental signs (some of them being totally and other partial, edentulous). Results: The edentulous degree and also the uncoordinated function of the stomatognathic muscles system were factors that significantly influenced the pain and articular noises. Clinical overview was clearly dominated by the muscular signs. Conclusions: Both groups of enrolled patients displayed different stages of stomatognathic system dysfunctional syndrome (SSDS). Considering the high incidence of Parkinson disease within the third age population, the accurate evaluation and therapy of the stomatognathic system disorders becomes mandatory for the dental practitioner. Moreover, the proper treatment plan should corroborate the dental therapy with treatment of the systemic disorder

The Influence of Beverages on Resin Composites: An In Vitro Study

Dental composites, through their structural diversity, represent the biomaterials frequently used in dental reconstructive therapy. The aim of our study was to observe the influence of different beverage environment conditions on seven types of obturation dental materials with different compositions. Our research focused on the surface modification analysis of the materials after the immersion in the different beverages; in this regard, we used the EDAX technique correlated with the energy-dispersive X-ray fluorescence (XRF). The pH of the drinks and that of the simulated saliva solution were determined by the titrimetric method, a sodium hydroxide solution 0.1 mol/dm3 was prepared and used for the titration. An amount of 5 mL of each analyzed solution was added to 15 mL of distilled water to obtain a dilution, to which 3 drops of phenolphthalein (as a color indicator—Phenolphthalein, 3,3-Bis(4-hydroxyphenyl)-1(3H)-isobenzofuranone, C20H14O4 Mw: 318.32, purchased from Merck) were added for each analysis. For each solution, the experiment was repeated three times in order to obtain accurate results. The results of our study materialized into a real plea for modifying the patients’ behavior in terms of diet and preferences for acidic drinks, so that their quality-of-life valence can be improved by keeping the composite materials in a long-term unalterable state on the one hand; on the other hand, systemic damage can be prevented as well

[WITHDRAWN] Interdisciplinarity in Complex Therapeutic Approach of Psychiatric Patients with Dysfunctional Syndrome of the Stomatognated System

Diseases in the maxillofacial sphere and especially the dysfunctional syndrome of the stomatognathic system have many connections and interferences with the psychiatric pathology and why not last, but not least the appearance and aesthetics that have an impact on social life and success. On the other hand, there has been a significant increase in the use of antipsychotics in recent decades. The negative impact on oral health has also increased. The ability to diagnose mental illness is essential due to the social stigma associated with these disorders and a correct differential diagnose as well. This article describes the oro-dental rehabilitation of one case, psychiatrically treated, with mandibular and maxilla missing teeth and dental destruction and prosthetic damage, temporomandibular disorders pathology due to the disbalanced occlusion and depression and anxiety, with specific medication, fixed and removable hybrid prosthesis and intra oral complex rehabilitation.Editor's Note | On 27.11.2023 the authors requested the paper withdrawal.

Periodontal Disease Diagnosis in the Context of Oral Rehabilitation Approaches

Periodontal diseases generally correspond to a disturbance in the balance between the host’s defense and the micro-organisms colonizing the periodontal environment. The exact mechanisms underlying the destruction of the periodontium remain to be fully elucidated. Our study aims to quantify the main bacteria pool involved in periodontal pathology and associate it with other factors involved in the onset of periodontal disease so that an accurate diagnosis with profound implications for the therapeutic algorithm can be developed. Micro-Ident tests, based on the polymerase chain reaction (PCR) technique, were used for the study group, chosen for their high specificity in identifying periodontopathogenic bacteria and determining their relative numbers. The results of our study indicate an increased concentration of 4.50 (number of strains) for Capnocytophaga, followed by Tannerella forsythia, in a concentration of 3.50; the next highest concentration percentages are for Treponemei denticola, and Prevotela intermedia, low concentrations were found for Fusobacterium nucleatum and Porphyromonas. The concentration of each type of bacteria is reflected in the clinical picture and constitutes the starting point for a targeted antibiotic therapy. Following the effects of antibiotic-targeted therapy obtained from the evaluation of the micro-IDent B test results on the periodontium of the supporting teeth, we observed that the values of the periodontal indices change slightly at 3-month intervals with a predominance of plaque, bleeding, and gingival indices, and less in the indices concerning the depth of the probing pocket and the loss of attachment on the buccal and oral surfaces. In conclusion, our study emphasizes a direct relationship between the subgingival tartar presence and the patients age, gingival recession, presence of periodontal pockets, dental mobility, as well as the periodontal indexes: plaque index, bleeding index, and gingival index. The correlation of negative values of periodontal indices with the nature of the involved bacteria materializes in relevant starting points in the elaboration of the periodontal diagnosis of the therapeutic plan and predictability of the prognosis of oral rehabilitation

INTERDISCIPLINARITY APPROACHES IN CONTEXT OF COMPLEX INTRAORAL REHABILITATON TREATMENT AT YOUNG PACIENTS WITH SOCIAL ANXIETY -CLINICAL EXAMINATION –PART 1

Social anxiety is one of the most common psychological disorders along with depression and generalized anxiety. Avoiding eye contact, persistent fear of being judged and negatively evaluated by others, and social isolation are just some of the specific features of this type of anxiety.As part of the complex oral rehabilitation treatment, we also faced such a case which involved a lot of attention and time, but to which was also added the joint and muscle pathology, superposing with the social the dental treatments anxiety , the patient needing a special complex treatment approach

The Quantification of Salivary Flow and pH and Stomatognathic System Rehabilitation Interference in Patients with Oral Diseases, Post-Radiotherapy

Xerostomia is a common complication post-radiotherapy in patients with oral cancer. The acute and long-term side effects can considerably reduce the patient’s quality of life. The aim of our study was to perform analysis of salivary flow and pH in patients after radiotherapy. Methodology: Clinical and laboratory evaluations were conducted in the 2014–2019 period; out of a total 58 subjects aged between 45 and 84, 28 individuals with oral cancer were selected from St. Spiridon Hospital, Clinic of Maxillo-facial Surgery and Oncology Hospital, Iasi post-radiotherapy. Results: Significant downsized mean values of the hydrogen ion concentration (pH) in saliva (p < 0.001) were recorded in patients after radiotherapy, pH value = 4.580 (±1.051). The mean value of resting salivary flow (MRSF) was significantly lower for the group of patients with radiotherapy (MRSF) = 0.145 mL/min. In 89.29% of cases (25 post-radiotherapy cases), in order to perform oral complex rehabilitation treatment, several endodontic and periodontal treatments were performed. A total of 78.57% of the cases received complex oral rehabilitation as mobile or hybrid prostheses or fixed solutions. Conclusion: Understanding post-radiotherapy salivary biochemic modifications in patients with oral cancer could be of critical importance, in view of related oral disorder prevention
