In this narrative review, we aim to evaluate surgical and orthodontic approaches for treating maxillary canine impactions, evaluate their effectiveness, and compare the two treatment modalities.We reviewed several studies on databases such as Google Scholar, PUBMED, and MEDLINE to update recent knowledge for canine impactions and their treatment. We reviewed and included studies that matched our research objectives, including orthodontic management, open and closed eruption techniques, and contact and tooth alignment surgery.Successful treatment results of canine impactions were reported increasingly in literature, and good clinical outcomes were observed in most cases. However, factors such as the severity of the impaction, patient age, and surgical experience were found to influence the choice of surgical technique and success rates. Complications associated with surgical management of maxillary canine impactions were also reported. These complications, which include tooth resorption, postoperative infection, ankylosis, and damage to adjacent structures, are generally rare but emphasize the importance of careful patient selection, surgical planning accuracy, and emphasis on diligent postoperative care.Findings highlight surgical procedures' effectiveness, outcomes, and challenges to help clinicians make informed decisions and improve patient care. The results underscore the importance of evidence-based decision-making and a multidisciplinary approach for successful clinical outcomes. Future research will focus on long-term stability, patient-reported outcomes, and exploring emerging techniques to further improve the management of maxillary canine impactions.","PeriodicalId":502477,"journal":{"name":"European Journal of General Dentistry","volume":"37 31","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141645089","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The patented rotary file system, Kedo S, designed for primary teeth, introduced a single file generation for efficient pulp therapy. However, there are currently no studies assessing canal preparation in primary mandibular canine using nano-computed tomography (nano-CT). This study aims to evaluate the efficacy of rotary file systems (Kedo S plus, Kedo SG blue) against traditional hand files in root canal preparation of primary mandibular canines using nano-CT. Materials and Methods  This in vitro study was performed in extracted primary mandibular canine based on certain inclusion and exclusion criteria. Samples were prepared and working length was determined before the preoperative scan using a high-resolution nano-CT device (SkyScan 2214, Bruker, Kontich, Belgium). A single well-experienced pediatric dentist prepared the canals using three file systems: Kedo S plus, Kedo SG blue, and hand K-files. A postoperative scan was performed similar to preoperative scan. Image reconstruction was performed with NRecon software for three-dimensional volumetric visualization and analysis of the root canals. Results  Kedo S plus displayed significant alterations in volumetric, surface area, and instrumented areas postpreparation compared with Kedo SG blue and hand files. Statistical analysis revealed significant differences in volumetric and surface changes between Kedo S plus and hand files. Conclusion  Rotary file systems, especially Kedo S plus, resulted in increased canal volume and surface area with minimal uninstrumented areas, showing promise for primary dentition root canal preparations. Further clinical assessments are warranted to validate these findings.","PeriodicalId":502477,"journal":{"name":"European Journal of General Dentistry","volume":"341 7","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141686741","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dental students experience higher levels of academic stress during their education that requires clinical and patient management skills. Coronavirus disease 2019 (COVID-19) fatigue is a type of chronic stress that has put the population under high stress for an extended period of time. This study aimed to assess the impact of pandemic burnout and fatigue on the gingival health of academically stressed dental students.\u0000 Materials and Methods This study compared junior (n = 20) and senior (n = 20) year dental students undergoing their final year exams. Gingival health was assessed by plaque index (PI), gingival index (GI), and modified papillary bleeding index (MPBI). Academic stress was measured by the dental environmental stress questionnaire, while COVID-19 burnout was judged by COVID-19 student stress questionnaire (CSSQ).\u0000 Statistical Analysis Quantitative data were expressed as mean, standard deviation and median Student's t-test was used to compare two categories for normally distributed quantitative variables, while significance of the obtained results was judged at the 5% level.\u0000 Results Gingival health evaluation revealed no significant differences in GI and PI; however, MPBI in juniors was more significant (p = < 0.001). Academic stress was significantly higher among seniors (p = 0.001); nevertheless, CSSQ showed low levels of stress toward the pandemic with no significant differences.\u0000 Conclusion Gingival diseases are multifactorial in nature; stress is a biologically influencing factor as well.

This sampling technique is invasive and causes discomfort to the patient. Saliva swabs (SSs) can be used as an alternative noninvasive method; however, there are limited data confirming its suitability for the diagnosis of COVID-19. The aim of this study was to test the ability to detect COVID-19 using SSs in comparison with NPSs in the Baghdad Alkark sector.\u0000 Materials and Methods Six hundred and fifty patients were included in this study, and written informed consent was obtained from all the study participants. Paired NPSs and SSs were collected at the same time from each participant between days 3 and 5 after disease initiation. SSs were taken from the sublingual area. An RT‒PCR assay was used to detect the viral ribonucleic acid (RNA) of SARS-CoV-2 for the diagnosis of COVID-19. The chi-squared test was used for data analysis, with p < 0.05 considered significant.\u0000 Results Out of 650 participants with suspected COVID-19 (313 males and 145 females), 313 were confirmed to be positive for COVID-19 by quantitative RT–PCR (RT‒qPCR) using both samples.

Data collection was conducted using the Modified Dental Anxiety Scale, which includes 5-point Likert responses, five questions, and demonstrates good internal consistency.\u0000 Results The findings indicate that there was no statistically significant difference in the occurrence of dental anxiety between male and female schoolchildren (p = 0.374). In total, 1.9, 8.7, 10.1, 36.4, and 42.9% of the schoolchildren reported experiencing no dental anxiety, mild, moderate, extreme, and severe levels of dental anxiety, respectively. Furthermore, the results reveal that 2.1% of the variance in children's dental anxiety scores could be accounted for by factors such as gender, age, socioeconomic status, and parental education.
