Amalgam Restorations

Aim: The aim of this study was to detect the use of amalgam versus resin composite restorations placed in permanent posterior vital teeth among dentists practicing in Saudi Arabia and dental interns training in Saudi Arabia. Materials and Methods: 318 patients aged ≥ 8 years were randomly selected and clinically examined for amalgam and resin composite restorations placed in permanent posterior vital teeth by dentists and by dental interns in Saudi Arabia. The restorations were placed in teeth preparations Class I and Class II. Also, bitewing and or periapical radiographs were used to define the depth of the cavity. The data obtained were documented in a patient examination form then statistically analyzed using Chi-Square Test or Fisher-Freeman-Halton Test and Spearman’s Correlation Coefficient. Results: Composite was the predominant kind of restoration placed by dental interns, and dentists placed more composite restorations than amalgam ones. There was an insignificant relationship between the kind of restoration placed by dental interns (amalgam, composite) and the tooth type (maxillary / mandibular premolar, maxillary / mandibular molar), the class of tooth preparation, the cavity depth, the age of the patient, and the gender of the patient p> 0.05. However, there was a significant relationship between the kind of restoration placed by dentists (amalgam, composite) and the cavity depth p < 0.05. Also, dentists placed more composite restorations in maxillary first premolars and in young patients 8-29 years, while they placed more amalgam restorations in mandibular second molars and in older patients 41-50 years p < 0.05. There was an insignificant relationship between the kind of restoration placed by dentists (amalgam, composite) and the class of cavity preparation and the gender of the patient p > 0.05. Conclusion: Both dentists and dental interns used composite restorative material more than amalgam, but dentists placed more amalgam restorations than dental interns. Dental interns mainly used composite. Keywords: Amalgam, Composite, Class, Dentist, Depth, Intern, Type.

Purpose: To compare the restorative material used in the treatment of posterior teeth taught and performed in two Dental Schools (UFRGS and ULBRA) and in 8 basic health units (BHU) from the Public Health System in Porto Alegre, Brazil. Materials and methods: Data referring the teaching of restorative procedures using amalgam (AM) or resin (R) were obtained through the analysis of patient’s files and questionnaires applied to final year dental students. Information regarding restorative procedures at BHU was obtained through patient’s records and a questionnaire applied to the dentists. The type of restorative material used in both BHU and Dental Schools were compared by chi-square test. Results: At UFRGS, 327 restorations were performed, 78.28% R and 21.72% AM, and at ULBRA 366 restorations, 92.63% R and 7.37% AM. At BHU, 1664 restorations were performed (35.93% R and 64.07% AM). A major proportion of AM restorations was performed in the Public Health Service in comparison to both Dental Schools, in which resin restorations prevailed (p=0.000). Conclusion: The change from AM to R in the dental material choice for posterior teeth at Dental Schools was not followed by the Public Health System, where the AM is still widely used in posterior teeth.

Aim: A retrospective clinical audit was carried out on records of endodontic treatment performed by dental undergraduates. The audit was performed to evaluate the technical quality of root canal fillings performed by dental undergraduates and determine the associated factors. Methods: 140 records of patients who had received root canal treatment by dental undergraduates were evaluated through periapical radiographs by two examiners (κ =0.74). The root canal fillings had their quality evaluated according to extent, condensation and presence of procedural mishap. Possible factors associated with technical quality such as tooth type, canal curvature, student level and quality of record keeping were evaluated. Data were statistically analyzed using chi-square test (p<0.05). Results: Among the 140 root-filled teeth, acceptable extent, condensation and no-mishap were observed in 72.1%, 66.4% and 77.9% cases respectively. Overall, the technical quality of 68 (48.6%) root-filled teeth was considered acceptable. Overall, non-acceptable root canal fillings were significantly more likely to be observed in molars (69.2%), moderately and severely curved canals (71.4%) and junior students (61.5%). There was no association between acceptable root canal fillings and quality of record keeping. Conclusions: The technical quality of root canal fillings was acceptable in 48.6% cases and it was associated with tooth type, degree of canal curvature and student seniority.

Amalgam Restorations

Amalgam has been used in Dentistry for about 150 to 200 years and is still under use due to its low cost, ease of application, strength and durability. It is an alloy of mercury, is an excellent and versatile restorative material. The development of various tooth coloured cements and resins serves as an alternative and have reduced the use of amalgam. Yet, amalgam stands as one of the excellent restorative materials. The aim of the study was to assess the knowledge, awareness and practice of dental amalgam among dental students in a private dental school. Study was conducted as a cross sectional questionnaire based study among the dental students. The study was conducted as an online survey as it is timesaving and a majority of the population can be covered. There were one hundred participants involved in this online survey from second year, third years, final years and internship. The questionnaire consisting of ten questions were posted for an online survey using google forms. The validity of the questionnaire was cross verified by experts. The data were extracted and tabulated in MS Excel sheets with respect to each question and their response. The data obtained were subjected to statistical analysis using SPSS software v20. Chi square test was done to assess the association between the variables. The descriptive data obtained were plotted in bar graphs. It was evident that interns had adequate knowledge about amalgam restorations than other participants.

Antimicrobial-resistance in Enterobacterales is a serious concern in Saudi Arabia. The present study retrospectively analyzed the antibiograms of Enterobacterales identified from 1 January 2019 to 31 December 2019 from a referral hospital in the Aljouf region of Saudi Arabia. The revised document of the Centers for Disease Control (CDC) CR-2015 and Magiorakos et al.’s document were used to define carbapenem resistance and classify resistant bacteria, respectively. The association of carbapenem resistance, MDR, and ESBL with various sociodemographic characteristics was assessed by the chi-square test and odds ratios. In total, 617 Enterobacterales were identified. The predominant (n = 533 (86.4%)) isolates consisted of 232 (37.6%), 200 (32.4%), and 101 (16.4%) Escherichia coli, Klebsiella pneumoniae, and Proteus mirabilis, respectively. In general, 432 (81.0%) and 128 (24.0%) isolates were of MDR and ESBL, respectively. The MDR strains were recovered in higher frequency from intensive care units (OR = 3.24 (1.78–5.91); p < 0.01). E. coli and K. pneumoniae resistance rates to imipenem (2.55 (1.21–5.37); p < 0.01) and meropenem (2.18 (1.01–4.67); p < 0.04), respectively, were significantly higher in winter. The data emphasize that MDR isolates among Enterobacterales are highly prevalent. The studied Enterobacterales exhibited seasonal variation in antimicrobial resistance rates towards carbapenems and ESBL activity.

SUMMARY Bulk-fill composites have been introduced to facilitate the placement of deep direct resin composite restorations. This study aimed at analyzing the cervical marginal integrity of bulk-fill vs incremental and open-sandwich class II resin composite restorations after thermomechanical cycling using replica scanning electron microscopy (SEM) and ranking according to the World Dental Federation (FDI) criteria. Box-only class II cavities were prepared in 91 maxillary premolars with the gingival margin placed 1 mm above and below the cemento-enamel junction. Eighty-four premolars were divided into self-etch and total-etch groups, then subdivided into six restorative subgroups (n=7): 1-Tetric Ceram HB (TC) was used incrementally and in the open-sandwich technique with 2-Tetric EvoFlow (EF) and 3-Smart Dentin Replacement (SD). Bulk-fill restoratives were 4-SonicFill (SF), 5-Tetric N-Ceram Bulk Fill (TN), and 6-Tetric EvoCeram Bulk Fill (TE). In subgroups 1-5, Tetric N-Bond self-etch and Tetric N-Bond total-etch adhesives were used, whereas in subgroup 6, AdheSE self-etch and ExciTE F total etch were used. One more group (n=7) was restored with Filtek P90 Low Shrink Posterior Restorative (P9) only in combination with its self-etch P90 System Adhesive. Materials were manipulated and light cured (20 seconds, 1600 mW/cm2), and restorations were artificially aged by thermo-occlusal load cycling. Polyvinyl-siloxane impressions were taken and poured with epoxy resin. Resin replicas were examined by SEM (200×) for marginal sealing, and percentages of perfect margins were analyzed. Moreover, samples were examined using loupes (3.5×) and explorers and categorized according to the FDI criteria. Results were statistically analyzed (SEM by Kruskal-Wallis test and FDI by chi-square test) without significant differences in either the replica SEM groups (p=0.848) or the FDI criteria groups (p&gt;0.05). The best SEM results at the enamel margin were in TC+EF/total-etch and SF/total-etch and at the cementum margins were in SF/total-etch and TE/self-etch, while the worst were in TC/self-etch at both margins. According to FDI criteria, the best was TE/total-etch at the enamel margin, and the poorest was P9/self-etch at the cementum margin. Groups did not differ significantly, and there was a strong correlation in results between replica SEM and FDI ranking.

ABSTRACT Aim The aim of this study was to define the prevalence and severity of temporomandibular disorders (TMD) among Iranian dental and nondental students who attended Shiraz University of Medical Sciences. Materials and methods The samples consisted of 200 subjects, 100 dental and 100 nondental students (equal distribution between males and females). Subjects ages ranged from 18 to 30 years (24.07 ± 2.93). A functional evaluation was performed using the Helkimo dysfunction index (Di). Data were evaluated by the Chi-square test. Results Among the total study population, 71% showed some degree of dysfunction. Prevalence ratio in dental students was 80%, while in nondental students was 62% (p < 0.05, odds ratio = 0.679). With respect to gender, women (80%) were more affected than men (62%). A significant relationship was found between gender and the occurrence of TMD (p < 0.05). Conclusion A high prevalence of signs of TMD in Iranian university students was seen which was greater in dental students and women. Clinical significance The results of this study showed that the prevalence of TMD among dental students and women was significantly higher than nondental students and men. These findings might be due to poor postural style or emotional stress during dental practice. How to cite this article Bahrani F, Ghadiri P, Vojdani M.

Introduction: Tooth restoration is a common, routine procedure among dentists but still has its own difficulties especially for posterior teeth. As it is a straightforward procedure, some dentists are not aware of the difficulties that may contribute in reducing the longevity of the filling. The aim of the study is to determine the difficulties encountered during and after placement of restorative materials in deep cavities. Materials and methods: Standardized questionnaires were divided randomly among general private dental practitioners in Kuala Lumpur. Chi-square test was used to determine any significant factors associated with difficulties of material placement. Results: This study showed that the most frequent difficulties encountered among practitioners were to obtain good moisture control (39.0%). No significant association was found between obtaining good moisture control and year of clinical experience (p= 0.286) and also place of graduation with the manipulation of the materials (p= 0.542). Conclusion: Dental practitioners claimed that it was difficult to obtain good moisture control in placement of posterior restoration. Thus, it is an obligation of dental practitioners to practice proper isolation and good manipulation of materials on posterior restoration.
