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.

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.

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.

ABSTRACT Objectives: The study aimed to evaluate and compare the dental prosthetic status and treatment needs of adult population in Jizan, Saudi Arabia, in relation to the age. Materials and Methods: A total of 1779 people aged 35–74 years from 4 survey areas (Hay al matar, Mahata khams, Dara ut tawhid, and Suq ad dakhili) selected through convenient sampling, around Jizan University, were surveyed, using the WHO survey criteria, 1997. Statistical Analysis: Number and percentages were calculated, and univariate analysis was performed using Chi-square test at 5% level of significance. Results: Different forms of prosthesis were present among patients in the upper (19.9%) and lower (19%) arches, respectively. Prosthetic treatment need was recognized in subjects, 56.4% for the upper and 57.2% for the lower arches, respectively. The prosthetic status and treatment needs differed statistically with respect to age. Conclusion: More than half of the surveyed adult populations were in need of some or the other forms of prosthesis. This study provides data for an oral health-care provider program for Jizan.

SUMMARY Objective: To compare the 24-month clinical performance of two different resin composites in class II slot restorations. Methods and Materials: Thirty-seven patients having at least two approximal carious lesions were enrolled in the study. A total of 116 teeth (58 pairs) were restored with either a silorane-based composite (Filtek Silorane) and its self-etch adhesive (Silorane Adhesive System, 3M ESPE) or a methacrylate-based packable resin composite (X-tra Fil) and its self-etch adhesive (Futurabond NR, VOCO GmbH) according to the toss of a coin. The restorations were evaluated at baseline and at six-, 12-, and 24-month recalls by two calibrated examiners according to the modified US Public Health Service criteria. The comparison of the two restorative materials for each category was performed with the Pearson chi-square test. Within group differences of the materials at different recall times were compared using the Cochran Q and Friedman tests. Bonferroni-adjusted McNemar test was used when significant difference was found (p&lt;0.05). Results: After 24 months, no statistically significant differences were found between the two restorative materials for the criteria evaluated. Conclusions: Both silorane- and methacrylate-based resin composites showed clinically acceptable performance in class II slot restorations after 24 months.

The use of resin composite for routine restoration of cavities in posterior teeth is now commonplace, and will increase further following the Minamata Agreement and patient requests for tooth-coloured restorations in their posterior teeth. It is therefore relevant to evaluate the published survival rates of such restorations. A Medline search identified 144 possible studies, this being reduced to 24 when inclusion criteria were introduced. Of these, ten directly compared amalgam and composite, eight were cohort studies, and six were systematic reviews. It was concluded that posterior composites may provide restorations of satisfactory longevity and with survival rates generally similar to those published on amalgam restorations. However, the ability of the operator in placing the restoration may have a profound effect. CPD/Clinical Relevance: With the increasing use of composite for restorations in posterior teeth, it is relevant to note that these may provide good rates for survival.

Abstract Objectives The purpose of the current study was to collect information about some techniques and armamentarium currently used by the Saudi Board of Endodontics residents in relation to the technical steps of root canal therapy. Materials and Methods A web-based survey was sent to the Saudi Board of Endodontics residents, based in the western area of Saudi Arabia. The survey assessed controversial concepts, and collected information regarding new instruments and materials, used in the technical steps of nonsurgical root canal treatment. A one-sample chi-square test, with a 95% level of significance, was applied to determine whether there were significant differences between respondents’ answers. Results A total of 45 out of 50 residents (90%) responded to the questionnaire. The majority of Saudi Board residents of Endodontics, who participated in this survey, used the mean of working length (ML) measured by periapical X-Ray and apex locator in the presence of a radiographic lesion (63.3%), and maintained apical patency in all cases (80.0%). ProTaper Universal (40%) and ProTaper Next (41.2%) were the most common NiTi rotary systems used for root canal instrumentation. Thirty percent of respondents used adjunct device with irrigation, and 80% advocated smear layer removal. Zinc oxide–eugenol-based sealers were the most common used sealers (70%), and most residents (86.6%) did not advocate sealer extrusion. Conclusions This study revealed that residents of the Saudi Board of Endodontics program adopt new endodontic technologies. There is, however, a need for more investigations regarding this objective, including responses from all residents in Saudi Arabia.

e21714 Background: Compared to other regions, the burden of breast cancer (BC) in Mexico is disproportionately borne by younger women. Yet, their particular needs and concerns have remained understudied, including treatment-related sexual adverse effects. We aim to assess the sexual function and satisfaction in Mexican young women with BC undergoing treatment. Methods: This is a prospective sexual assessment study in BC patients of the pilot phase of the Joven y Fuerte Mexican cohort (N=96). Sexual health was assessed using the Female Sexual Function Index (FSFI) and the Sexual Satisfaction Inventory (SSI) at two points in time: baseline (BL) and 6-months follow-up (6-FU). FSFI and SSI scores lower than 26.55 and 111, respectively, were defined as sexual morbidity. Differences between proportions of BL and 6-FU were examined with Pearson chi-square test. Matched t-tests were used to test for differences in the domains of the FSFI and in the SSI total score. Results: 70 women completed the FSFI at both time points and 69 the SSI. Our results showed a high percentage of sexual dysfunction among Mexican women at BL and 6-FU (61.4% and 74.3%, respectively, p<0.001), as well as an elevated proportion of sexual low satisfaction at both time lines (40.6% and 43.5%, p=0.004). Most 6-FU FSFI domain scores were significantly worse than those at BL (Table 1). There were no significant differences in the SSI total score (102.31 [BL] vs 96.11 [6-FU], p=0.16). Conclusions: Mexican young patients with BC report significant sexual morbidity at BL, which even worsens after the first short follow-up. Reasons for the low sexual performance among Mexican women remain understudied and should be actively sought. In this prospective study, data will be annually collected for five years. This information will provide valuable information in an often-neglected matter of BC patients’ care. [Table: see text]

Abstract Objective: To investigate the differences in the congenital missing teeth pattern in terms of tooth type (permanent maxillary lateral incisor [MLI] and maxillary second premolar [MSP]) and sidedness (cleft vs noncleft) between boys and girls in Korean unilateral cleft lip and alveolus (UCLA) and unilateral cleft lip and palate (UCLP) patients. Materials and Methods: This study used the charts, models, radiographs, and intraoral photographs of 90 UCLA patients and 204 UCLP patients (ages 6 to 13 years). Binomial test, chi-square test, Fisher exact test, maximum likelihood analysis of variance, and the odds ratio were performed. Results: According to the relationship between the congenital missing teeth pattern and the cleft type, the UCLP patients had 2.98 times more missing MLIs and 1.80 times more missing MSPs than did the UCLA patients. The MLI was congenitally missing more in boys than in girls, but the MSP showed the opposite tendency. Boys had a higher frequency of congenital missing MLIs and MSPs on the cleft side than did girls. However, on the noncleft side and both sides, girls had a higher frequency of congenital missing MLIs and MSPs than did boys. Results showed a gender-dominant pattern of congenital missing MLIs and MSPs. Conclusion: These results suggest that gender and cleft type might affect the congenital missing teeth pattern in terms of tooth type and sidedness.
