RESUMEN
The nutritional needs already increased by adolescent growth, activity, and stress are further exacerbated by the physical, physiological, and psychological stress that orthodontic treatment causes. Hence, the main objective of this systematic review was to analyze the relationship between adequate nutrition and its impact on orthodontic treatment success rates. Using relevant keywords, reference searches, and citation searches, the databases such as PubMed-Medical Literature Analysis and Retrieval System Online, Web of Science, Cochrane, and Scopus were all searched. "Diet," "Minerals," "Nutrition," "Orthodontics," and "Vitamins" were the search terms used to scour the database. The 10 studies selected for the systematic review and subsequent meta-analysis could not conclusively establish the correlation between proper nutrition and its impact on orthodontic treatment of the patient. There was virtually little connection between patients' dietary intake and the effectiveness of their orthodontic treatment. Additionally, a direct causal link between the two could not be established legitimately because the majority of the studies reviewed only noted an impact during the early stages of the treatment.

RESUMEN
A variety of metals and alloys are employed in the field of orthodontics, primary of which happen to be the construction of wires. Through this systematic review, we aimed to assess the various metallurgical characteristics of the said metals and alloys. Four hundred and eighty-two documents in total were found after a thorough search of the online journals, and 169 of the papers were initially chosen. Ultimately, 16 documents were selected that satisfied the necessary inclusion and exclusion criteria, primarily in vitro studies, literature reviews, and comparative analyses. NiTi alloy was found to be the most commonly used alloy in construction of orthodontic wires across all the studies that we had selected for our review. It also had better performance and consistency in terms of its usage as depicted by the meta-analysis performed, with stainless steel wires being a close second primarily due to its lesser cost compared to the former. Metallurgy and orthodontics are inextricably linked with one another. The various components of orthodontics such as wires, pliers, and other instruments utilize the metallurgical characteristics of metals and alloys that are specially prepared for the challenges of this field.

RESUMEN
AIM: To determine the prevalence of malocclusions and the need for orthodontic treatment in a sample of school-going adolescents in the Najran city, Kingdom of Saudi Arabia (KSA). METHODOLOGY: This cross-sectional study was conducted among 1094 school-going Saudi male adolescents. The age range of the sampled adolescents was 13-18 years, and none of them had any history of orthodontic treatment. A survey chart related to malocclusion was designed and filled up after clinical examination by a single experienced and calibrated examiner. The need for orthodontic treatment was assessed using the Index of Orthodontic Treatment Need (IOTN). RESULT: The present study's findings demonstrated 61.2% of the samples with Angle's Class I malocclusions, 27.5% with Class II, and 11.4% of samples with Class III malocclusion. A significant difference was observed between the different classes of malocclusion (P < 0.001). Most samples presented normal overjet, crossbite, and no reverse overjet, deep bite, or open bite. The number of samples with no treatment need was 573 (52.37%), with slight treatment in 185 (16.91%) samples, moderate treatment needs in 123 (11.24%) samples, and severe and extreme treatment needs were 109 (9.96%) and 104 (9.50%), respectively. A significant difference was observed between the samples with no or slight treatment need (grades 1 and 2), moderate need (grade 3), and definite treatment need (grades 4 and 5) (p < 0.001). CONCLUSION: The prevalence of malocclusion and IOTNs among the sample of school-going adolescents in the Najran city was 47.63%. However, 9.63% of those samples required immediate attention for orthodontic treatment.
RESUMEN
BACKGROUND: Microesthetics in orthodontics, which focuses on subtly and precisely enhancing a patient's smile's esthetics, has seen a rise in popularity in recent years. The objective of this systematic study was to assess our present understanding of orthodontic microesthetics. METHODS: A thorough search was done using the terms "microesthetics in orthodontics," "aesthetic orthodontics," "orthodontic aesthetics," and "orthodontic smile design" across different databases. Articles published between 2011 and 2022 were considered for selection in this review. RESULTS: Five studies were selected for the review. The meta-analysis found a statistically significant and clinically relevant improvement in microesthetic parameters due to orthodontic treatment. The odds ratio estimate was 0.32 (95% confidence interval (95% CI): 0.28 to 0.37), suggesting a noticeable effect of orthodontic treatment on microesthetic parameters. The forest plot also showed an overall risk ratio of 0.57 (95% CI: 0.53 to 0.61) and a risk difference of -0.28 (95% CI: -0.31 to -0.24) for noticeable versus negligible effects of orthodontic treatment on microesthetic parameter in patients. The heterogeneity was significant among the studies, with a Chi-square value of 15.34 (P = 0.004) and 14.79 (P = 0.005) for the odds ratio and risk difference, respectively, indicating a moderate level of heterogeneity. CONCLUSION: The results of this study's review and meta-analysis point to a statistically significant and clinically meaningful difference in the microesthetic parameters between individuals who received orthodontic treatment and those who did not. The heterogeneity statistics, however, indicates significant variation between research studies. REGISTRATION: This review protocol was registered on the International Prospective Register of Systematic Reviews (PROSPERO; registration number: CRD42022397219).
