Abstract
INTRODUCTION The aim of this systematic review was to provide guidelines for decision-making during orthodontic treatment planning of infra-occluded deciduous molars with or without their successors in children and adolescents. EVIDENCE ACQUISITION Computerized search was conducted on Medline via PubMed, and Cochrane Library. Articles published until 2020 in English language were analyzed following the Preferred Reporting Items for Systematic Reviews (PRISMA) Checklist. Observational and interventional longitudinal studies reporting the treatment of ankylosed deciduous molars with or without successor tooth in 3 to 15-year-old patients were included. EVIDENCE SYNTHESIS In case of ankylosis with presence of successor, exfoliation took place in 77% of teeth, while extraction involved 23%. Infra-occlusion happened in 53% of teeth (worsening in 52%), alveolar bone loss in 37%, mesial tipping of first permanent molar in 5%, and over-eruption of antagonist in no cases (after exfoliation and eruption of successor). In case of ankylosis without successor, exfoliation took place in 1% of teeth, progression of infra-occlusion in 42%, progression of root resorption in 58%, development of mesial tipping of first permanent molars in 25%, while no case of antagonist over-eruption was reported. CONCLUSIONS When the permanent tooth is present and the ankylosed tooth is slightly or moderately infra-occluded, observation is appropriate. In case of severe infra-occlusion or absence of successor, tooth extraction may be considered together with orthodontic space closure, transplantation, or prosthetic replacement. Alternatively, nonextraction and a prosthetic build-up may be considered.

Abstract
Objective To compare the dental and skeletal effects of intermaxillary elastics on the correction of mild Angle's Class II division 1 malocclusion with clear aligner treatment (CA) versus fixed multibracket (FMB) in growing patients. Settings and sample population The study sample consisted of 49 consecutively patients (mean age ± SD 12.9 ± 1.7 years), 32 females and 17 males referred from the School of Orthodontics of the University of Bratislava Comenius (Slovakia). All patients were treated with a non‐extraction orthodontic treatment, 25 with FMB and 24 with CA. Methods The cephalometric analysis was performed at the beginning (T0) and the end of the treatment (T1). The t test for unpaired data was carried out to compare cephalometric values at T0 and changes at T1‐T0 between the two groups. The level of significance was set as P < .0035. Results The two groups showed no statistically significant differences (ANPg = −0.1°; P = .762) in the correction of the sagittal intermaxillary relation. The analysis of vertical skeletal changes showed no statistically significant effects on mandibular inclination (SN/MP = 0.1°; P = .840). The two treatments had a statistically significant and clinically relevant difference in controlling the inclination of the lower incisors (L1/GoGn = 4.8°, CAG = −0.5°± 3.9°; FMB = 4.3°± 5.8°; P < .001). Conclusions Class II elastics combined with CA and FMB produce a similar correction on sagittal discrepancies in growing patients. CA presented a better control in the proclination of the lower incisors. CA and elastics might be a good alternative in the correction of mild Class II malocclusion in cases where a proclination of lower incisors is unwanted.

Abstract
Resistance to sliding (RS) between the bracket, wire, and ligature has been largely debated in orthodontics. Despite the extensive number of published studies, the lack of discussion of the methods used has led to little understanding of this phenomenon. The aim of this study was to discuss variables affecting RS in orthodontics and to suggest an operative protocol. The search included PubMed©, Medline©, and the Cochrane Library©. References of full-text articles were manually analyzed. English-language articles published between January 2007 and January 2017 that performed an in vitro analysis of RS between the bracket, wire, and ligature were included. Study methods were analyzed based on the study design, description of materials, and experimental setup, and a protocol to standardize the testing methods was proposed. From 404 articles identified from the database search and 242 records selected from published references, 101 were eligible for the qualitative analysis, and six for the quantitative synthesis. One or more experimental parameters were incompatible and a meta-analysis was not performed. Major factors regarding the study design, materials, and experimental setup were not clearly described by most studies. The normal force, that is the force perpendicular to the sliding of the wire and one of the most relevant variable in RS, was not considered by most studies. Different variables were introduced, often acting as confounding factors. A protocol was suggested to standardize testing procedures and enhance the understanding of in vitro findings.

Abstract
The use of elastics to close a diastema or correct tooth malpositions can create unintended consequences if not properly controlled. The American Association of Orthodontists recently issued a consumer alert, warning of “a substantial risk for irreparable damage” from a new trend called “do-it-yourself” orthodontics, consisting of patients autonomously using elastics to correct tooth position. The elastics can work their way below the gums and around the roots of the teeth, causing damage to the periodontium and even resulting in tooth loss. The cost of implants to replace these teeth would well exceed the cost of proper orthodontic care. This damage could also occur in a dental office, when a general dentist tries to perform a simplified orthodontic correction of a minor tooth malposition. The present case report describes a case of tooth loss caused by a displaced intraoral elastic, which occurred during a simple preprosthetic orthodontic treatment.

Abstract
BACKGROUND The purpose of this study was to compare the results obtained using the rapid palate expander (RPE) and the quad-helix (QH) in the treatment of cleft lip and palate (CLP) patients in mixed dentition. METHODS In this retrospective clinical trial 28 CLP patients in mixed dentition were enrolled and divided into a group RPE, consisting of 11 patients, and a group QH, consisting of 17 patients. Plaster models before and after treatment were scanned and measurements were made using the software Ortho Analyzer. Measurements, obtained with a digital gauge on plaster models, were regarded as the gold standard and compared with those on digital models. Measurement error was assessed using the Dahlberg formula and the reliability and accuracy of the measurements were evaluated by the interclass coefficient (ICC). The unpaired t-test was used to compare the group RPE with the group QH. RESULTS Measurement error found with Dahlberg's method was 0.36. ICC values indicated a strong repeatability of the evaluator's measurements on digital models and an almost perfect repeatability on plaster models, with a value of 0.79 and 0.93, respectively. The ICC for the accuracy of the measurements on digital models was equal to 0.74, indicating a strong agreement with measurements realized on plaster models. Patients in the QH group presented a gain of the anterior palatal diameter significantly greater than those in the RPE group. CONCLUSIONS The use in mixed dentition of the quad-helix allows obtaining a greater gain of the anterior palatal diameter and a greater symmetry of the dental arch.

Abstract
The increasing emphasis placed on patients' rights, in dentistry as well as in other areas, is also having repercussions on the structure of the relationship between health care staff, the under-age patient and his /her parents. The authors reflect about the decision-making process when the patient is a minor in the field of dentistry and underline the role of the parties involved (dentist, parents, under-age patient) in different circumstances (e.g. ordinary care or non-routine care; urgent situations; conflict between parents; refusal of the parents; disagreement between the parents and the child, refusal of the under-age patient; etc.). The Law must first ensure that the minors' needs for protection are met by awarding their parents the power and duty to care for them and, thus, also to take health care decisions in their interest. At the same time, domestic legislation and international legislation supports the need to give greater weight to minors' opinions as they approach the age of majority and, therefore, as they acquire a certain degree of maturity. The rights of under-age patients are safeguarded by actively involving them in the decision-making process, with particular reference to their right to information and right to be heard, to the extent that their age and understanding allow, with due consideration to the specific situation.
