Objective: This study aimed to evaluate the efficacy of "Embrace WetBond", a fluoride-releasing self-adhesive resin cement in preventing the development of white spot lesions (WSLs) during orthodontic treatment.Methods: This retrospective cross-sectional study was conducted on the dental records of 140 patients treated with fixed orthodontic appliances in a private orthodontic clinic in Tehran, Iran. Patients were divided into two equal groups based on the type of adhesive used for bonding orthodontic attachments: Group 1 (control), Transbond XT and Group 2, Embrace wetBond. The prevalence and severity of WSLs were assessed in all teeth from the first molar to the first molar of both jaws using post-treatment photographs. The data were analyzed by chi-square and Mann-Whitney U test and a P-value0.05). The highest prevalence of WSLs was in maxillary lateral incisors (21.4%) and mandibular first molars (15.7%) in the Transbond XT group and maxillary lateral incisors (7.1%) in the WetBond group.Conclusions: The findings of this study suggest that Embrace WetBond adhesive may effectively reduce the risk of WSL development in patients treated with fixed orthodontic appliances. This fluoride-releasing self-adhesive resin cement can be considered a suitable alternative to traditional cement in orthodontic practice.

Masticatory performance is considered an important step in the beginning of the digestive process and considering the patient’s aesthetic and functional factors, it is necessary to choose appropriate treatments. Based on the evidence during orthodontic treatment, the restoration of the physiological function of masticatory performance should not be neglected. The present study aimed to evaluate the association between orthodontic treatment and improved masticatory performance and oral health related to quality of life. In the present study, all articles published till the end of August 2023 were extracted by two trained researchers independently through a search in databases like PubMed, Scopus, Science Direct, ISI, Web of Knowledge, Elsevier, Wiley, and Embase, and Google Scholar search engine using keywords and their combinations. Data analysis was done using the fixed effects model in a meta-analysis, by STATA (version 17); a P-value of less than 0.05 was considered significant. Based on the results, the mean difference in masticatory performance between pre-treatment and post-treatment was 2.23 (MD: 2.23; 95CI, 2.17, 2.29. p

The patient's health and quality of life would probably be improved with dental implant. This study aimed to evaluate the risk factors associated with dental implants place by orthodontic treatment. In this study, information on risk factors associated with implants of sites prepared, radiology stereotypes and hospitalized were obtined from databases such as Scopus, Google scholar and PubMed, and 58 articles were included for this purpose. After analyzing the articles, 24 articles were not accepted and 34 articles were accepted, then, 16 articles were miscarriage and 18 articles were scientific sources. The results showed that orthodontic treatment has a significant effect on a person's sense of beauty and would possibly increase self-confidence and quality of life. The stability of the implant in the healing phase depends on the quality and quantity of the bone. Also, the width of the bone is one of the important issues in creating a successful treatment. When an implant fails, problems and symptoms of failure usually occur within the first year after surgery. After one year, there is only about a 1% chance of failure, and on average only 1% of all implants fail each year.

Aims: This study aimed to assess the effect of G-CEM, a fluoride-releasing cement, on the development of white spot lesions (WSLs) and their severity around orthodontic brackets. Methods and Materials: This case-control study was conducted by reviewing 140 dental records of fixed orthodontic patients presenting to an orthodontic clinic. The patients were assigned to two groups (n = 70). In group 1, Transbond XT resin cement, and in group 2, G-CEM had been used for bracket bonding. The frequency and severity of WSLs in each group were evaluated by assessing the available post-treatment photographs of patients and notes left by their orthodontist in their records in this regard. The number of teeth with WSLs in each patient was recorded, and the severity of lesions was categorised by Gorelick's analysis. Statistical Analysis: Comparisons were made using independent t-test, Wilcoxon test and Mann--Whitney test (alpha = 0.05). Results: In both the maxilla and mandible, the prevalence of WSLs was significantly higher in the Transbond XT group than in the G-CEM group (P = 0.01). The difference in frequency of WSLs between the maxilla and mandible was not significant within each group (P > 0.05). Tooth #22 had the highest frequency of WSLs (11.4%) in the Transbond XT group, while teeth #12 and #36 had the highest frequency of WSLs (2.9%) in the G-CEM group. The difference in frequency of WSLs was not significant between males and females (P > 0.05). Conclusion: Bracket bonding with G-CEM fluoride-releasing cement significantly reduced the development of WSLs around orthodontic brackets. [ABSTRACT FROM AUTHOR]
