Orthodontics and periodontics are intricately linked since adult orthodontics often implicate the periodontium. Periodontal intervention is needed throughout all phases of orthodontic treatment, from orthodontic diagnosis to mid-treatment periodontal assessment and postoperative evaluation. Invariably, periodontal health affects orthodontic success. Conversely, orthodontic tooth movements may serve as adjunctive therapy in patients with periodontal disease. This review aimed to provide a comprehensive understanding of the orthodontic-periodontic relationship for optimizing therapeutic strategies and achieving the best treatment outcomes in patients.

The variety in shape and type of dental implants in the present time is considered one of the most successful evolutions in dentistry. This facilitates dental treatment options to restore patient function and appearance. However, numerous significant factors influence the predictability of survival or the success rates of dental implants, some of which, such as vitamin D levels, have not been included in many studies. The main purpose of this systematic review was to investigate whether there is a relationship between low serum levels of vitamin D and early dental implant failures (EDIFs). Our literature search involved international databases including PubMed, Directory of Open Access Journals (DOAJ), and Web of Science. Initially, according to our search criteria, 1200 studies were found. After excluding duplicates, incomplete studies, and studies not meeting our inclusion criteria, only six human studies were included in this research and analyzed. Finally, upon meticulous analysis of included studies, this systematic review revealed inconsistent results in articles with respect to the association between vitamin D deficiency and implant failures. Large-scale studies, especially clinically relevant studies, on this subject is recommended.

Studies suggest that breastfeeding can help resolve skeletal and dental malocclusions. But there is no clear evidence that breastfeeding duration affects skeletal or dental malocclusions in pediatric patients. Therefore, the objective of this narrative review was to review all the available updated articles on the impact of breastfeeding and non-nutritive sucking behaviors in deciduous and mixed teeth on different forms of malocclusions. The following electronic databases were used PubMed, Scopus, Web of Science, and Google Scholar to obtain relevant data that met the eligibility criteria. The studies in this narrative review were covered the last 10 years. Primary research identified 368 papers. In addition, three articles were selected from the gray literature for consideration. On the basis of duplication, title, abstract, methodology and/or irrelevant information, 177 articles were removed. This narrative review was focused on seventeen articles that met the eligibility criteria. When it comes to deciduous and mixed teeth, breastfeeding appears to decrease the occurrence of skeletal class II, posterior crossbite, and malocclusion. There appears to be a favorable correlation between prolong duration of breastfeeding and risk reduction. To avoid bias in the results, more longitudinal study is warranted, with data collected prospectively on the duration of exclusive breastfeeding and non-nutritive sucking behaviors, using specific survey questions, and subsequent clinical investigation of the occlusal status at the deciduous, mixed, and permanent teeth stages.

Enamel microcracks (EMCs) arising during the removal of metal orthodontic brackets represent a considerable challenge in dentistry. This in vitro study aims to explore the impacts of thermocycling, the types of orthodontic bonding agent, and curing techniques on the enamel surface of the tooth structure following the debonding of orthodontic metal brackets. It also examines the incidence, number, length, and direction of EMCs on the buccal surface of the tooth. Additionally, the study compares adhesive remnant index (ARI) scores and bracket failure post-debonding. Forty extracted human maxillary canines were divided into ten groups, including intact enamel negative controls (groups 1, 2) and groups (3–8) with metal brackets bonded using two different bonding agents and curing techniques. Following bonding, half of the groups underwent thermocycling testing. EMCs, ARI scores, and bracket failure modes were evaluated. The formation, length, and direction of cracks did not significantly differ among groups, regardless of experimental conditions. Thermocycling had no significant effect on ARI scores or bracket failure modes. However, significant variations were observed among curing technique groups, with seventh-generation bonding agents demonstrating potential effectiveness in achieving complete adhesive removal. The study underscores the importance of considering bonding agent systems and curing protocols to optimize bond outcomes and minimize the risk of metal bracket failure in orthodontic treatment.

Objective: The aim of this systematic review was to evaluate the effects of ultrasonic instrumentation and air polishing on surface roughness and marginal integrity of dental restorations, addressing their potential adverse impacts on various biomaterials. Materials and Methods: A search of five databases, supplemented by manual searches, identified relevant laboratory studies. Forty‐two studies met the inclusion criteria, with data on surface roughness and marginal quality extracted for analysis. The RoBDEMAT tool was used to assess risk of bias. Results: Ultrasonic instrumentation significantly increased roughness, particularly in resin‐modified glass ionomer cements and resin‐based composites, whereas zirconia and lithium disilicate were less affected. Air polishing, especially with sodium bicarbonate and calcium carbonate powders, also increased roughness. Erythritol and glycine powders were the least abrasive. Both ultrasonic scaling and air polishing negatively impacted marginal quality. The RoBDEMAT assessments revealed shortcomings in randomization, sample size justification, and blinding. Conclusions: Ultrasonic instrumentation and air polishing can adversely affect dental restorations, with the degree of impact varying by biomaterial and debridement method. Low‐abrasive powders, such as erythritol and glycine, are recommended. Methodological refinements and clinical studies are needed to enhance the applicability of these findings to patient care. Clinical Significance: This review highlights the critical need to choose appropriate debridement methods to minimize iatrogenic damage to dental restorations. Low‐abrasive air polishing powders, such as erythritol and glycine, are recommended for the removal of soft deposits and stains to preserve surface smoothness and marginal integrity.

Despite the rise in popularity of ceramic braces for adults, the risk of enamel microcracks (EMCs) upon removal remains a significant drawback for both dental professionals and patients. Our study aimed to assess the effects of thermocycling, pre-curing, and co-curing techniques with different bonding agents on the enamel surface of teeth after the removal of ceramic brackets. We also examined the incidence, quantity, length, and direction of EMCs on tooth surfaces. Additionally, the adhesive remnant index (ARI) scores and orthodontic bracket bond failure modes were evaluated and compared. The study divided 40 extracted upper canine teeth into ten groups for further analysis. Two groups had intact enamel as the negative control, while the remaining groups had orthodontic ceramic brackets bonded using different bonding agents and curing techniques. Thermocycling was performed in five groups, and ARI was assessed after debonding. The study findings were statistically significant (p < 0.05) in demonstrating the impact of curing techniques on EMCs and debonding outcomes. Seventh-generation bonding agents resulted in complete adhesive removal (ARI = 0). The microcracks’ incidence, number, and length showed insignificant results. Differences in ARI between thermocycler and non-thermocycler samples were insignificant. Both co-curing and pre-curing techniques yielded comparable ARI results. This study highlights the importance of using advanced bonding agents to minimize enamel damage during ceramic bracket debonding.
