RESUMEN

Introduction: This study aimed to compare the efficacy of ibuprofen, Novafen, mefenamic acid (MA), and celecoxib for pain relief in patients with symptomatic irreversible pulpitis prior to emergency endodontic treatment. Materials and Methods: This clinical trial was conducted on 120 patients with moderate to severe pain due to symptomatic irreversible pulpitis seeking emergency endodontic treatment. The patients were randomly divided into 4 groups to receive Novafen, MA, Celecoxib, and ibuprofen. The pain score of patients was measured before and 1 hour after analgesic intake using a visual analog scale (VAS). The success of analgesic treatment was analyzed by the binary logistic regression model. Results: A total of 117 patients including 76 females and 41 males with a mean age of 30.29 years completed the study and were statistically analyzed. Ibuprofen had the highest analgesic efficacy followed by Novafen, and caused a significantly greater reduction in pain score compared with MA and celecoxib [OR (Ibuprofen vs MA)=1.28, OR (Ibuprofen vs Celecoxib)=3.74, OR (Novafen vs MA)=2.94, OR (Novafen vs Celecoxib)=2.94, P<0.05]. Ibuprofen and Novafen had no significant difference in analgesic efficacy (P>0.05). Baseline pain score was a predictive factor for the success of analgesics (P<0.05). The success of analgesic treatment decreased by 0.68 times with each unit increase in pain score (P<0.05). Gender and age of patients had no significant effect on success of analgesics (P>0.05). Conclusion: Both ibuprofen and Novafen can serve as the analgesics of choice for pain relief in patients with symptomatic irreversible pulpitis with moderate to severe pain when emergency endodontic treatment cannot be immediately performed.

RESUMEN

BACKGROUND: Antiseptic mouthwashes are useful adjuncts to daily brushing and flossing for the control of dental plaque and gingivitis. The objective of the present study was to compare the effect of three mouthwashes: chlorhexidine, essential oils and cetylpyridinium chloride on oral health-related quality of life, gingival health, tongue coating and also to compare their potential side effects after 2-week consumption. METHODS: Sixty participants were enrolled in this study and were divided into four groups (three mouthwash groups plus no mouthwash group). At the beginning, scaling and cleaning were performed and the following parameters were recorded: oral health impact profile (OHIP-5) questionnaire, tongue coating index, modified gingival index, calculus surface index, modified Lobene stain index and a questionnaire for side effects. Each group has followed up in 2 weeks. Data were analysed using paired t-test, ANOVA, Fisher's exact test and Pearson chi-square. RESULTS: At the end of second week, all three mouthwashes significantly improved OHIP-5 score and reduced modified gingival index whereas essential oils and cetylpyridinium chloride significantly reduced tongue coating index when compared to control group (p < 0.05). The differences between four groups were significant for calculus formation, dental staining and reported burning sensation and changes of taste sensation and perception (p < 0.05). CONCLUSION: The use of all three mouthwashes has been effective in controlling and reducing gingivitis and tongue coating; however, it appeared that essential oils has the minimum and Chlorhexidine has the maximum side effects. Moreover, the use of all three mouthwashes has been examined to improve the quality of life. Overall, essential oils mouthwash has the best performance among these three mouthwashes.

RESUMEN

ABSTRACT Objective: To measure the Oral Health-Related Quality of Life (OHRQoL) and compare children with and without parental care. Material and Methods: This cross-sectional study was conducted on 160 schoolchildren with parental care and 100 orphans in Kerman, Iran. After fulfilling the questionnaire voluntarily, a clinical examination was performed, and indices such as decayed, missing, and filled teeth (DMFT), molar-incisor hypoplasia (MIH), modified gingival index (MGI), traumatic dental injury (TDI), and malocclusion were recorded. Data were statistically analyzed using SPSS version 25 via the ANOVA, Pearson's correlation coefficient test, Chi-Square test, and descriptive statistics. Results: Children without parents scored poorly for OHQRoL items compared to those with parents (p<0.001). DMFT was not significantly related to OHRQoL; however, missing teeth were correlated with the CPQ11-14 overall. Also, the TDI index had a significant relationship with CPQ mean score (p=0.02). Moreover, the difference in the mean CPQ11-14 score in children with TDI in the two groups was significant regarding the quality of life (0.031). Conclusion: OHRQoL differed significantly between children in the two groups, which can be influenced by gender and habits. Due to the vulnerability of welfare-supported children without parental care, these findings emphasize the value of preventive and health-promoting measures for this group of children.

RESUMEN

Introduction: This study aimed to evaluate the success rate of bypassing three NiTi rotary files (RaCe®, Hero 642®, and K3®), fractured in various root canal locations of extracted mandibular molars with two different canal curvatures. Materials and Methods: Ninety freshly extracted human first or second mandibular molars were selected. Three millimeters of the file tip (RaCe®, Hero 642®, and K3®), was fractured intentionally in the mesiobuccal root canal of each tooth by weakening the file in the last 3 mm of files #30 with 4% taper and preparing the root canals with two different degrees of curvature (n=30). Then, bypass possibility of the fractured files was evaluated using #8, #10, and #15 K-files and compared in different groups. In addition, the rate of accidental procedural errors was compared between these groups. Data were analyzed with univariate analysis and logistic regression models at a significance level of 0.05. Results: The overall success rate of bypassing was 61.1%. RaCe® files had the highest and the K3® files had the lowest bypass possibility rates (P=0.01); the greater the degree of canal curvature, the less successful the bypass procedure (P=0.01). The fracture of the files used to bypass was the most prevalent error. Conclusion: Based on this in vitro study the type of fractured file and the amount of canal curvature affected the success rate of the bypassing technique. In RaCe® files and the mild curvature group, the success rate was the highest.

RESUMEN

BACKGROUND AND AIM: Several research works show that anxiety is more common in women, low-income classes, and middle-aged and elderly populations. The present study aimed to investigate the role of positive and negative memories in patients' anxiety referred to the dental clinics, offices, and schools of Kerman, Iran, in 2018-2019. MATERIALS AND METHODS: In this cross-sectional, descriptive, analytical study, the participants were selected among individuals referred to the dental offices, schools, and clinics of Kerman, Iran. In this study, 500 questionnaires were distributed among the participants (based on census method), and of these, 482 of which were reviewed (response rate = 96.4%). The questionnaire used in this study contained four categories of questions, including demographic information, general questions about dentistry, Corah's Dental Anxiety Scale, and Autobiographical Memory Questionnaire. Analysis of variance, t-test, and Chi-square test were used to analyze. RESULTS: Overall, 281 participants were female, and 201 were male. Based on the findings, dental visits were enjoyable and pleasant experiences for 154 participants, and 165 patients were anxious while the dentist prepared for a restorative treatment. This study showed that people with negative memories had more anxiety. Anxiety was also significantly associated with positive memories, higher education, and gender (female) (P < 0.05). Also, the most negative memories of dental treatments were associated with increased anxiety about dental treatments in adults (P < 0.05), while positive memories did not have a relationship any with decreased anxiety (P > 0.05). CONCLUSION: The most negative memories of dental treatments were associated with increased anxiety about dental treatments in adults, while positive memories did not have any expected inverse relationship with anxiety.
