Comparative Clinical Study

Objective: To compare the success rate of different obturation procedures in primary mandibular second molars clinically and also by digital radiovisiography. Methods: A total of 40 children aged between 4-8 years with deeply carious mandibular second primary molars indicated for single session pulpectomy were selected. Canals were obturated with Metapex. The 3 study groups (Endodontic plugger, Handheld lentulospiral, Navi Tip syringe) were compared with the control group (reamer) both clinically and radiovisiographically. The data collected were statistically analyzed using Pearson’s Chi-square and Fisher’s exact test. Results: The use of Navi tip syringe led to the least number of voids followed by Endodontic plugger and Reamer and the highest number of voids was reported with Lentulospiral. Navitip presented maximum number of optimally filled cases followed by Endodontic plugger and Lentulospiral and least number of optimally filled cases with reamer. However, there was no statistically significant difference (p>0.05) in any of the groups with clinical (pain and tenderness to percussion) and radiographic parameters (presence or absence of voids and length of obturation). Conclusion: Within the limitations of the present study, though the clinical outcome was statistically insignificant, Navitip syringe exhibited encouraging results and is a promising option for obturation in primary teeth.

Objective: To evaluate the effectiveness of placing a resorbable collagen barrier in impeding the extrusion of obturation material in primary molars undergoing resorption. Study design: All the 94 canals in 47 mandibular molars were allocated to 2 groups- Group ‘A’- 47 canals with collagen barrier (Test group) and Group ‘B’- 47 canals without collagen barrier (Control group) based on randomization protocol. Pulpectomy was performed and obturation of both test and control canals were radiographically assessed. Pearson’s chi – square test was applied to analyze the results. The significance level was predetermined at p < 0.05. Results: Among the test group, 93.6% of the canals showed no extrusion while, 6.4% showed visible extrusion of the material outside the apex. In the control group, 83% showed no extrusion whereas 17% of the canals showed visible extrusion outside the apex. But no significant difference was noted (p>0.05). Conclusion: The placement of resorbable collagen barrier in the apical third of the canal prevented the extrusion of obturating material beyond the apex in resorbing primary molars.

Abstract Background Clinicians in critical care medicine considered dapsone administration to treat SARS-CoV-2 inflammasome. Dapsone is useful in the molecular regulation of Nod-like receptor family pyrin domain-containing 3 (NLRP3). Objective To study the targeting of NLRP3 itself or up-/downstream factors of the NLRP3 inflammasome by dapsone must be responsible for its observed preventive effects, functioning as a competitor. Methods This is case series with or without intervention; a cross-sectional study. We set out to use objective criteria of improvement, such as A. a reduction in the FIO2 requirement and B. a decrease in the progression of hypoxia. We treated the patients with standard COVID-19 ARDS treatment with dapsone 100 mg to target NLRP3 inflammasomes. Results The 22 cases were treated with standard COVID-19 therapy with dapsone (trial group), and the 22 cases were the control group. The comparison was made assuming that only decreased FIO2 was influential in the trial and control groups, which applied to only the ARDS onset stage. The chi-square statistic is 5.1836. The p-value is .02280. Fisher’s exact test statistic value is 0.0433. (The result is significant at p < .05) Furthermore, the ARDS-onset mortality rates were 0% (with dapsone) and 40% (without dapsone). Conclusion There was a significant difference in dapsone treatment results in the ARDS-onset group. We confirmed that dapsone clinically treated the onset of ARDS by targeting SARS-CoV-2-activated inflammasomes. Like chemically reacting substances, inflammasome and dapsone are competing, proving that it is only effective in treating early ARDS.

Aims: To evaluate the mandibular bone cortical of patients with mucopolysaccharidosis on panoramic radiograph, through radiomorfometric indices. Study Design: Case-control study. Place and Duration of Study: Sample: Department of Diagnostic Imaging of the Universidade Estadual da Paraíba, Campus VIII, in the city of Araruna, PB, between January and December of 2015. Methodology: Panoramic radiographs of sixteen patients with mucopolysaccharidosis and 32 controls, organized by gender and age, composed the sample. The mandibular panoramic index, gonial index, antegonial index and mental index were evaluated. Pearson's Chi-square test, Fisher's exact test and Mann-Whitney test were used to statistical analysis with a level of significance of 5.0%. Results: Mucopolysaccharidosis patients were mostly female (62.5%), with a mean age of 12.31 + 7.16 years, MPS VI (50.0%) being the most prevalent. Patients with mucopolysaccharidosis had higher values in the gonial (1.86+0.48), the antegonical (4.36+1.24) and the mental (5.24+1.21). However, only the antegoniac index presented a significant difference (P=0.047). Conclusion: The antegoniac index was higher in patients with mucopolysaccharidosis and the other radiomorphometric measures were similar to those observed in the control group. Apparently, mucopolysaccharidosis is not related to decreased bone to mandibular quality.

Abstract Introduction: Physicaltherapy in patients with osteoarthritis (OA) acts to decrease pain, increase joint functionality and to promote improvement in quality of life. Objective: To analyze the effect of a structured program of aquatic physiotherapy (AP) on functional capacity (FC) and mobility of elderly people with OA. Methods: Prospective, quantitative and analytical, randomized control study. The sample consisted of 29 patients, aged 60 years or over, diagnosed with OA, randomly allocated to the intervention group (IG), composed of 17 participants who underwent BP for two months, and to the control group (CG) of 12 participants. The primary outcome was measured by the WOMAC instruments and six-minute walk test. As a secondary endpoint, the Timed Up and Go Test measured mobility. Descriptive statistical analysis was used to present the data, with mean and standard deviation values. The comparison between groups for potential confounding factors and in relation to evolution was performed using the non-parametric chi-square test, Fisher's exact test and the Kruskal-Wallis test, and Dunn's test for multiple comparisons. The differences were considered statistically significant when p < 0.05. Results: There was a significant difference in physical and functional parameters related to pain (p < 0.001), stiffness (p < 0.001) physical activity (p < 0.001), distance covered in six minutes (p = 0.001), and mobility (p < 0.001) when comparing IG to CG. Conclusion: The structured AP program effectively contributed to the improvement of FC and mobility of elderly people with knee OA.

Abstract Background: Carious primary molars, symptomless, or with reversible pulpitis are most frequently treated with pulpotomy to maintain arch integrity, otherwise they would be extracted. The present study was conducted to assess clinically and radiographically the success rate of three capping materials: Nanohydroxyapatite (NHA), Mineral Trioxide Aggregate (MTA) and Formocresol (FC) in pulpotomy of primary molars.Methods: A clinical trial was carried out on healthy, four to eight years old children, with 72 second primary molars indicated for pulpotomy. Molars were divided into 3 equal groups (24 teeth each) designated to NHA (group 1), MTA (group 2) and FC (group 3) as pulp medicaments. Treated teeth were finally restored with stainless steel crowns. Subjects were monitored clinically and radiographically at three, six- and twelve-months time intervals. The difference in success rate between groups at the same time point was evaluated using Chi square test. Significant level was set at p <0.05. Statistical analysis was performed using a commercially available software program SPSS version 21.Results: The highest overall success was recorded in MTA group (90.5%), followed by FC group (76.2%). The least overall success was found in NHA group (72.2%). Statistical analysis of data revealed that the difference between the three groups was not statistically significant.Conclusions: MTA is still the material of choice for pulpotomy in primary molars. Further studies are recommended to evaluate the use of NHA as a potential alternative to MTA.Trial registration: This trial was registered on Clincal.Trial.gov (https://clinicaltrials.gov.), on February 8, 2019 (Retrospectively registered). The protocol ID is 181053. The Identifier is NCT03833557.

Aim: This study aimed to evaluate the accuracy of three apex locators in enlarged teeth with different apical diameters using files that are compatible and incompatible with the apical diameters. Methodology: Sixty lower premolars were used in this study. The actual canal length was determined with a stereo microscope, and the teeth were divided into three different groups (G25, G40 and G50). The teeth in G25, G40 and G50 were enlarged in actual canal length with apical diameters of 0.25, 0.40 and 0.50 mm using hand files and Reciproc R25, R40, and R50, respectively. In the electronic measurements, a #15 hand file was used in each group, and #25, #40 and #50 hand files that were compatible with the apical diameters of the teeth in the groups were used. An alginate model was created with enlarged teeth. The electronic working length was determined for each tooth using Root ZX Mini, Raypex 6, and Propex Pixi electronic apex locators (EALs). Results: Electronic measurement results that were shorter by 0.50 mm or longer by 0.05 mm than the actual length were considered unsuccessful; otherwise, they were deemed successful. Analysis of variance was used to evaluate the accuracy of the EALs with different files in the same apical diameter. For the different apical diameters, the chi-square exact test was used to evaluate the accuracy effect of using files that were incompatible with each apical diameter. The level of significance was p > 0.05. In all the groups, the measured lengths were closer to the actual canal length with the use of #25, #40 and #50 hand files that were compatible with the apical diameters. However, there was no significant difference between the measurements with the #15 hand file (p > 0.05). According to the electronic measurement results made with the #15 hand file in teeth with 0.25, 0.40 and 0.50 apical diameters, the use of a file that was incompatible with the apical diameter did not have a significant effect on accuracy (p > 0.05). Conclusion: The use of a file that is compatible with the apical diameter of the tooth in the determination of the working length with measurement of EALs close to the actual canal length. The accuracy of EALs is not affected by the file size in electronic measurements with file sizes smaller than the apical diameter in teeth with apical diameters up to 0.50 mm.   How to cite this article: Öz H, Adıgüzel Ö, Kaya S.

Aim: To compare the clinical and radiographic effectiveness of chitosan and formocresol as pulpotomy medicaments in primary molars. Methods: Children of age 4-8 years old, who were physically and mentally healthy without any known medical history of systemic conditions contraindicating pulp therapy with at least one deep carious primary molars indicated for pulpotomy, were recruited. Pulpotomies were performed on 64 teeth divided into 2 groups, Group A (chitosan) and Group B (formocresol), followed by stainless steel crowns. Evaluation of clinical and radiological success was done at 1, 3 and 6 months follow up. Chi Square Test was used to compare the clinical and radiological parameters between study groups at different time intervals (p < 0.05) Results: Clinical success rate in both groups was 96.6% and radiographic success rate in chitosan was 96.6%, but formocresol was 89.6%. Conclusions: Chitosan was found to be an effective medicament for pulpotomy in primary molars. While chitosan also showed improved success rate compared to formocresol, it was not statistically significant.

Objective. The aim of this study was to compare to fracture resistance test of inlay restorations prepared using direct inlay technique (Gradia® Direct Composite) and Indirect Restoration System® (Gradia Indirect Composite) and CAD/CAD system (Vita Enamic® Block). Study Design. 48 noncarious extracted maxillary second primary molars were randomly divided into 4 groups with 12 in each group. All the teeth were prepared based on inlay class II preparations except for the control group. Other groups were restored with Gradia Direct Composite, Gradia Indirect Composite, and Vita Enamic Block, respectively. All restorations were cemented self-adhesive dual cure resin (3M Espe, RelyX™ Unicem Aplicap). A fracture test was performed using a compressive load. Results were analyzed using one-way analysis of variance and Duncan’s post hoc multiple comparison tests (α=0.05). Results. Vita Enamic Block and Gradia Indirect Composite showed significantly higher fracture resistance than Gradia Direct Composite (p<0.05). There was no significant difference fracture resistance between Vita Enamic Block and Gradia Indirect Composite (p>0.05). All restorations tested led to a significant reduction in fracture resistance (p<0.05). Conclusion. In inlay restorations, Indirect Restoration Systems and CAD/CAM systems were applied successfully together with the self-adhesive dual cure resin cements in primary molars.

Objective: the purpose of this study was to evaluate and compare, gross fracture, patient satisfaction, and marginal adaptation of anterior endocrowns restoring endodontically treated anterior teeth fabricated from IPS e.max press and CERASMART hybrid ceramics. Material and methods: A total of 24 patients were selected to receive an esthetic endocrowns for upper teeth in the esthetic zone (central incisor, lateral and canine).The 24 patients were divided into 2 groups (n=12 each), where Group (1): Control group: Teeth receiving IPS e.max press anterior endocrowns and Group (2): Intervention group: Tooth receiving CERASMART anterior endocrowns . After cementation all patients were recalled after 3, 6, 9, and 12 months. During each recall examination, USPHS criteria were adopted for clinical evaluation to score margin integrity and gross fracture. In addition, questionnaires were used to evaluate patients’ satisfaction and potential postoperative discomfort. Chi-square or Fisher’s Exact test were used to compare between qualitative variables in the two groups. Friedman’s test was used to study the changes by time within each group. The significance level was set at P ? 0.05. Results: Regarding gross fracture and marginal integrity, there was no statistically significant difference at any time interval between IPS e.max press and CERASMART endocrowns. All the patients were satisfied with their restorations till the end of the follow up period. Conclusions: CERASMART anterior endocrowns provided a promising treatment modality compared to ips press anterior endocrowns.
