Review
To explore the mandibular retromolar space length (MRSL), initial root-inner cortex contact percentage (IRCCP), and the various factors that influence mandibular molar distalization. Searches were undertaken in PubMed, EMBASE, Web of Science, Cochrane Library, Scopus, and grey literature (Google Scholar and OpenGrey) for eligible cross-sectional observational studies measuring the MRSL and IRCCP in healthy adult patients. The risk of bias and evidence quality were evaluated using the Joanna Briggs Institute's checklist and GRADE framework. Thirteen studies involving 1169 patients were included for qualitative synthesis. Seven of these studies were eligible for quantitative analysis. Meta-analysis showed that the mean MRSL at the subfurcation-6 mm plane in Asian normodivergent cases was 3.78 mm (95% confidence interval [CI]: 2.81-4.35; I = 79.7%) for skeletal Class-I malocclusions, 3.02 mm (95% CI: 2.10-3.94; I = 62.5%) for Class-II, and 4.43 mm (95% CI: 3.14-5.73; I = 75.1%) for Class-III. The mean MRSL at the sub-cementoenamel junction (CEJ)-10 mm plane for Asian, Class-I, normodivergent cases was 3.28 mm (95% CI: 2.44-4.12; I = 68.9%). The mean IRCCP for Asian, Class-I, normodivergent cases was 27.2% (95% CI: 0.22-0.32; I = 0%). In Asian normodivergent cases, MRSL ranges from 3.28 to 4.43 mm with a 27.2% IRCCP for Class-I. Cone-beam computed tomography imaging is recommended for measuring the MRSL in the apex region particularly before molar distalization. Factors influencing MRSL and IRCCP include different races, skeletal patterns, facial types, and third-molar status.

AIMS
The purpose of this systematic review was to evaluate the cost-effectiveness and acceptance of children and their parents of the Hall technique (HT) for dental rehabilitation in pediatric dentistry.
BACKGROUND
The approach of the HT is that of minimally invasive treatment of the dental element and is used exclusively on primary molars. Various studies in the literature point to HT as a restorative option well accepted by children and parents and quite predictable, with low retreatment rates and good cost-effectiveness for the management of primary molars with carious lesions. However, no systematic review in the literature has approached randomized clinical trials on these topics to produce a high level of evidence and help establish clinical HT protocols.
REVIEW RESULTS
Eight articles were selected for the systematic review. The HT was more cost-effective than procedures using other restorative materials. Regarding acceptance, in terms of esthetics, high percentages of satisfaction were reported for parents and children, with a divergence between studies in the comparison of esthetic preference with atraumatic restorative treatment. However, when considering crown cementation pain, comfort, anxiety, preference, and satisfaction, the HT was generally better evaluated when compared to other restorative materials.
CONCLUSION
The HT is an excellent restorative option when considering cost-effectiveness and acceptance and is recommended for use in daily clinical practice.
CLINICAL SIGNIFICANCE
Results indicate that HT is superior to other restorative materials regarding its acceptance by children and parents in terms of pain, comfort, anxiety, and crown preference and satisfaction. There were also high percentages of satisfaction with esthetics. Hall technique may initially appear expensive for dentists, but its effectiveness over time and the lesser need for consultations and reinventions ensure better cost-benefit than other restorative materials.

Review
Mandibular third-molar extraction is a frequently executed minor oral surgical procedure, with a subsequent recovery period lasting several days. Typically, preemptive administration of non-steroid anti-inflammatory drugs (NSAIDs) and steroids has been employed, resulting in a notable decrease in postoperative complications like pain, facial swelling, trismus, and alveolar osteitis. This systematic review's primary goal was to investigate the efficacy of preemptive analgesia with dexamethasone and diclofenac in minimizing the post-surgical complications following the surgical extraction of the mandibular third molars. The systematic search was carried out to identify relevant literature in digital databases including PubMed®, Cochrane Library, Web of Science, and Scopus, from January 1990 to January 2022. The search used specific keywords. The randomized clinical trials assessing the efficacy of dexamethasone and diclofenac or dexamethasone alone compared to diclofenac or placebo as preemptive analgesics were considered inclusion criteria for this systematic review. Case reports, literature reviews, letters to the editor, and non-English publications were not included. Two authors screened the titles and abstracts, and articles fulfilling the study criteria were included. After reading the full text and data collection, analysis was performed. The included article's bias was evaluated by the Risk of Bias 2 (RoB 2) tool. A digital database search yielded a total of 207 articles. After excluding duplicates and articles written in languages other than English, 90 were removed. Based on the title and abstract, out of 177, 95 studies were excluded. After full-text reading of 22 articles, 17 were eliminated because they did not meet the inclusion and exclusion criteria. The remaining five studies were found eligible and included in the systematic review. Four studies were of low risk, while one study had some concerns. Two studies evaluated the combination of dexamethasone with diclofenac, while three evaluated dexamethasone alone. Total samples included samples of 436 third-molar surgeries in 420 patients. There was a substantial decrease in the mean pain score and swelling measurement when diclofenac alone was compared with coadministration of diclofenac and dexamethasone. Preemptive administration of dexamethasone and diclofenac has been shown to effectively reduce pain and facial swelling, with the exception of trismus, in third-molar surgeries when compared to diclofenac alone. As a result, it is recommended to administer these drugs prior to the commencement of third-molar extraction. However, further research is mandatory, specifically good quality randomized controlled trials involving large cohorts, in order to assess any significant variations and validate these findings.

Review
Distalization is one of the most useful movements in orthodontic treatments. The aim of this systematic review is to analyze the effectiveness of lower molar distalization using clear aligner therapy (CAT). An electronic search was made from January 2012 to October 2022 using PubMed, Scopus, and LILACS databases without language limitations. This systematic review followed the Preferred Reporting Items for Systematic reviews and Meta-Analyses checklist. The search strategy resulted in 151 studies. A screening was performed to remove duplicates, and all the studies that did not respond to our questions for the title or abstract. Three studies underwent full text analysis. From the evaluation of the studies included in this review, it is possible to state that lower molar distalization is a clinical solution, but it is not a full bodily movement. CAT can provide more specifically a distal tipping movement. This is confirmed analyzing the discrepancy between expected movement and obtained movement. CAT can be considered a valid therapeutic option in patients with dental class III malocclusion, but it is obtained as a tipping movement instead of a body movement. Over-correction should be considered during the planning of the therapy.

Review
The primary goal of orthodontic therapy in pseudo-class III is to restore the proper dental connection by rectifying the canine and molar relationship to Class I through lower molar and premolar visualization, as well as providing normal anterior overjet. The purpose of this systematic study was to determine the efficacy of clear aligners in treating class III malocclusion with mandibular molar distalization. A wide range of searches were done on various search engines like Cochrane, Web of Science, Embase, PubMed, Scopus, and Google Scholar to collect relevant articles related to our study. This review's article selection was guided by the PRISMA flowchart. The electronic findings provided numerous articles with nearly 78 articles regarding clear aligners in class III malocclusion with molar distalization. From this, seven full-text papers were evaluated for eligibility criteria, with two articles being rejected with justification and five articles being elaborated in the current systematic review. The current evidence of this review suggested that the clear aligners were effective in correcting class III malocclusion with molar distalization. The amount of molar distalization is about 2 to 3 mm, which helps in achieving molar and canine relationship in class I, with a high compliance level and also improvement of the facial profile.

Meta-Analysis Review
BACKGROUND
Corticosteroids are used to manage pain after surgical tooth extractions. The authors assessed the effect of corticosteroids on acute postoperative pain in patients undergoing surgical tooth extractions of mandibular third molars.
TYPES OF STUDIES REVIEWED
The authors conducted a systematic review and meta-analysis. The authors searched the Epistemonikos database, including MEDLINE, Embase, Cochrane Central Register of Controlled Trials, and the US clinical trials registry (ClinicalTrials.gov) from inception until April 2023. Pairs of reviewers independently screened titles and abstracts, then full texts of trials were identified as potentially eligible. After duplicate data abstraction, the authors conducted random-effects meta-analyses. Risk of bias was assessed using Version 2 of the Cochrane Risk of Bias tool and certainty of the evidence was determined using the Grading of Recommendations Assessment, Development and Evaluation approach.
RESULTS
Forty randomized controlled trials proved eligible. The evidence suggested that corticosteroids compared with a placebo provided a trivial reduction in pain intensity measured 6 hours (mean difference, 8.79 points lower; 95% CI, 14.8 to 2.77 points lower; low certainty) and 24 hours after surgical tooth extraction (mean difference, 8.89 points lower; 95% CI, 10.71 to 7.06 points lower; very low certainty). The authors found no important difference between corticosteroids and a placebo with regard to incidence of postoperative infection (risk difference, 0%; 95% CI, -1% to 1%; low certainty) and alveolar osteitis (risk difference, 0%; 95% CI, -3% to 4%; very low certainty).
PRACTICAL IMPLICATIONS
Low and very low certainty evidence suggests that there is a trivial difference regarding postoperative pain intensity and adverse effects of corticosteroids administered orally, submucosally, or intramuscularly compared with a placebo in patients undergoing third-molar extractions.

Meta-Analysis
This systematic review evaluated the available evidence on whether children with molar incisor hypomineralization (MIH) have more dental fear and anxiety (DFA) and dental behavior management problems (DBMPs) than those without MIH (Prospero CDR42020203851). Unrestricted searches were performed in PubMed, Scopus, Web of Science, Lilacs, BBO, Embase, Cochrane Library, APA PsycINFO, Open Grey, and Google Scholar. Observational studies evaluating DFA and/or DBMPs in patients with and without MIH were eligible. Reviews, case reports, interventional studies, and those based on questionnaires to dentists were excluded. The methodological quality assessment was based on the Newcastle-Ottawa Scale. Random-effects meta-analyses were conducted to synthesize data on DFA. The certainty of evidence was performed according to GRADE. Seven studies that evaluated a total of 3,805 patients were included. All of them presented methodological issues, mainly in the comparability domain. Most studies observed no significant difference in DFA between children with and without MIH. The meta-analysis did not show a significant effect of MIH on the standardized units for the DFA scores (SMD = 0.03; 95%CI: -0.06-0.12; p = 0.53; I2 = 0%). Synthesis including only the results for severe cases of MIH also did not show a significant effect of the condition on DFA scores (MD = 8.68; 95%CI: -8.64-26.00; p = 0.33; I2 = 93%). Two articles found DBMPs were significantly more frequent in patients with MIH. The overall certainty of evidence was very low for both outcomes assessed. The current evidence suggests no difference in DFA between children with and without MIH; DBMPs are more common in patients with MIH. This information should be viewed with caution because of the very low quality evidence obtained.

Review
OBJECTIVE
To systematically review the effect of contraceptive methods following gestational trophoblastic disease (GTD) on timing of beta-human chorionic gonadotropin (hCG) remission, risk of post-molar gestational trophoblastic neoplasia (GTN), risk of unintended incident pregnancy, and interactions between contraceptive methods and disease treatment.
STUDY DESIGN
We conducted a search of primary literature with search terms related to GTD and contraception through April 2023 in PubMed and extrapolated our search to other platforms. Randomized controlled trials, observational studies and case reports were eligible for inclusion if they reported on patients with known GTD who received a contraceptive method for pregnancy prevention. Data was abstracted on our main outcomes of interest: timing of beta-hCG remission, risk of post-molar GTN, risk of unintended incident pregnancy, and interactions between contraceptive methods and cancer-directed systemic disease treatment (e.g., chemotherapy). At least two authors reviewed manuscripts at each screening stage with consensus reached before data extraction. Quality assessment checklists were used to assess risk of bias for the different study types.
RESULTS
Five thousand one hundred and five studies were identified in the database search, of which 42 were included for analysis. Eight thousand two hundred and ninety four participants were evaluated. Over half of the studies were case reports and only two were randomized controlled trials. While there was sparse data on all outcomes, no differences were noted in beta-hCG monitoring, risk of post-molar GTN or incident pregnancies between different contraceptive types. Interactions between contraceptive methods and cancer-directed systemic disease treatment (e.g., chemotherapy) or specific adverse events of contraceptive methods were not identified.
CONCLUSIONS
Data on contraceptive use following GTD is limited, but use of both hormonal and non-hormonal modern contraceptive methods appears safe. Counseling patients on the full range of contraceptive methods is important to help patients achieve their reproductive health goals and minimize the risk of disease progression through incomplete beta-hCG monitoring prior to future pregnancy.
IMPLICATIONS
Hormonal and non-hormonal contraceptive options may be used by patients following gestational trophoblastic disease without apparent changes in beta-hCG regression or risk of post-molar gestational trophoblastic neoplasia.

OBJECTIVES
Molar-root incisor malformation (MRIM) is a seldom reported condition characterised by disturbances in root development of first permanent molars. This systematic review aimed to collate the clinical characteristics of individuals diagnosed with MRIM.
MATERIALS AND METHODS
A systematic search strategy using PubMed, Embase, Web of Science, and SCOPUS databases was performed through to March 2023. Inclusion criteria were case reports or case series including a diagnosis consistent with MRIM. Critical appraisal for all included studies utilised the Joanna Briggs Institute (JBI) critical appraisal checklist for case reports and case series and collation of clinical characteristics was performed in JBI System for the Unified Management, Assessment and Review of Information program.
RESULTS
The search identified 157 studies from which 35 satisfied the inclusion criteria. After full-text review, a total of 23 papers described the MRIM dental anomaly and were included in this paper. A total of 130 reported cases were retrieved, with age ranging 3-32 years, and males affected 1.16:1 females. Presence of neurological conditions, premature birth history, medication, and surgery within first years of life were synthesised and described.
CONCLUSIONS
The aetiology of MRIM is yet to be determined but epigenetic changes from significant medical history in the first years of life are likely to influence the development of this root malformation. First permanent molars were most commonly affected, but clinicians should be aware that permanent central incisors, primary teeth and other permanent teeth may also be affected.

OBJECTIVE
The aim of this study was to summarize the results of the endocrown (EC) studies that compared tooth preparation designs, tooth types, and ceramic material types in relation to fracture force values.
MATERIALS AND METHODS
A full literature search was conducted in Web of Science, PubMed/Medline, EMBASE, Scopus, Cochrane Library, Google Scholar, and ProQuest electronic databases. The following keywords: Endocrown [(molar(s)) or (premolar(s) or (posterior teeth)] and Ceramic materials as (Lithium disilicate glass-ceramic; Zirconia; Lava Ultimate) and (fracture strength) or (fatigue) were used. Articles were manually searched utilizing their reference lists. Study selection was not restricted or limited to the time of publication, type of tested tooth, ceramic material, and EC design.
RESULTS
A total of 34 laboratory studies published between 2008 and 2023 were included in this systemic review. Twelve studies were published in the last 3 years, the mandibular molar was examined by 14 studies, and premolars in both arches were investigated, followed by premolars in both arches. Lithium disilicate glass-ceramic (LDGC) was the most used material for EC testing, followed by LAVA Ultimate and zirconia materials. The EC design with a 2 mm extension inside the pulp (14 studies) was the most used. Fracture forces of maxillary molars or premolars were nearly equal and lower than those of mandibular molars. Differences among the fracture forces of the tested ceramic materials were marginal. EC with 2 mm deep inside the pulp showed the highest fracture force.
CONCLUSIONS
Mandibular EC molars showed the highest fracture forces, followed by maxillary premolars and molars. No differences among the EC materials in the 2- and 4-mm pulpal extension designs were found, which had higher fracture forces than other designs.
