Review
BACKGROUND/OBJECTIVES
Oral habits are common etiological factors for anterior open bites (AOBs) in growing children and adolescents. The objective of this review was to provide a literature synthesis evaluating the effectiveness of open bite correction in growing individuals with the use of habit-interception appliances.
SEARCH METHODS
Electronic searches were conducted on PubMed, Embase, Cochrane Library, Web of Sciences, Scopus, Google Scholar, Scielo, and Lilacs databases. Trials registries were consulted for ongoing trials, and a partial grey literature search was also conducted.
SELECTION CRITERIA
The selection criteria included controlled clinical trials enrolling growing subjects who underwent habit-interception orthodontic treatment to correct dental and/or skeletal AOB.
DATA COLLECTION ANALYSIS
Data was grouped and analysed descriptively. A meta-analysis was only possible regarding crib therapy effectiveness. Qualitative appraisal was performed according to Cochrane Risk of Bias tool for randomized clinical trials (RCTs) and the MINORS tool for non-randomized clinical trials (nRCTs).
RESULTS
Two RCTs and nine nRCTs were identified. Most of them presented relevant limitations. Crib therapy demonstrated to be effective (+3.1mm overbite correction). However, most of the dental effects are seemingly lost with time; and the skeletal effects are still controversial. Other habit-interception appliances, such as spurs, were not sufficiently investigated.
CONCLUSIONS
Crib therapy appears to be effective on a short time basis. As for other habit-interception appliances, insufficient evidence could not provide reliable conclusions.

Review
OBJECTIVE
The objective of the study is to assess the effect of molar intrusion with temporary anchorage devices on the vertical facial morphology and mandibular rotation during open bite treatment in the permanent dentition.
METHODS
We performed a systematic review of the published data in seven electronic databases up to September 2015. We considered studies for inclusion if they were examining the effects of posterior teeth intrusion on the vertical facial morphology with open bite malocclusion in the permanent dentition. Study selection, risk of bias assessment, and data-extraction were performed in duplicate. Meta-analysis was not possible due to dissimilarity and heterogeneity among the included studies.
RESULTS
Out of the 42 articles that met the initial eligibility criteria, 12 studies were finally selected. Low level of scientific evidence was identified after risk of bias assessment of the included studies with no relevant randomized controlled trial performed. Out of the 12 selected studies, five studies used miniplates and seven studies used miniscrews. Mandibular counterclockwise rotation was found to be between 2.3° and 3.9° in six studies (as sassed by mandibular plane angle, between MeGo or GoGn and SN or FH plane) while it was less than 2° in the remaining studies.
CONCLUSIONS
Current weak evidence suggests that molar intrusion with temporary anchorage devices may cause mandibular counterclockwise autorotation. Future well-conducted and clearly reported multicenter randomized controlled trials that include a non-treatment control group are needed to make robust recommendations regarding the amount of mandibular rotation during open bite treatments.

Oral Diseases Mar 2022To evaluate whether individuals with osteogenesis imperfecta (OI) are more affected by malocclusion than individuals without OI. (Meta-Analysis)
Meta-Analysis Review
OBJECTIVE
To evaluate whether individuals with osteogenesis imperfecta (OI) are more affected by malocclusion than individuals without OI.
MATERIALS AND METHODS
Searches in PubMed, Ovid, Web of Science, Scopus, Lilacs and gray literature were performed. Data extraction was conducted by two researchers. Risk of bias assessment employing the Newcastle-Ottawa Scale and meta-analysis were conducted. Results were provided with mean difference (MD), odds ratio (OR) and 95% confidence interval (CI). Strength of evidence was determined.
RESULTS
Six cross-sectional studies were included. In comparison with individuals without OI, the group with OI had 19.69-fold greater chance of exhibiting Angle Class III malocclusion (OR = 19.69, CI: 9.00-43.09) and presenting anterior crossbite greater (MD = 6.08, CI: 2.40-9.77). Individuals without OI had a significantly greater ANB angle (MD = 3.88, CI: 1.15-6.61) and SNA angle (MD = 2.11, CI: 0.24-3.98) in comparison with those with OI. No difference between groups was found for SNB (MD = -0.50, CI: -2.21 to 1.21) and open bite (MD = 0.98, CI: -0.29 to 2.25). Most studies included had moderate methodological quality. Strength of evidence was low or very low.
CONCLUSIONS
The occurrence of Angle Class III malocclusion and anterior crossbite was greater among individuals with OI compared to those without OI. These findings can assist stakeholders about the occlusal abnormalities affecting OI individuals.

Meta-Analysis Review
OBJECTIVE
The aim of this systematic review and meta-analysis was to search for scientific evidence regarding the factors associated with traumatic dental injury (TDI) in the primary dentition.
METHODOLOGY
An electronic search addressing factors associated with TDI was conducted in the PubMed, ISI, LILACS, Cochrane Library, and Embase databases. Data were extracted and analyzed regarding risk factors, statistical test, effect measures, and study design.
RESULTS
The online search strategy led to the initial retrieval of 2566 articles. After evaluating the titles and abstracts, 24 papers were selected for complete review and data collection. TDI was associated with males (OR: 1.24; 95%CI: 1.09-1.41), inadequate lip coverage (OR: 1.81; 95%CI: 1.50-2.17), overbite (OR: 1.438; 95%CI: 0.94-2.19), and age (1 vs 2 years - OR: 0.47; 95%CI: 0.38-0.58; 2 vs 3 years - OR: 0.78; 95%CI: 0.67-0.91; 3 vs 4 years - OR: 0.82; 95%CI: 0.71-0.95). Overjet and anterior open bite were associated with TDI in the majority of studies.
CONCLUSIONS
Males, older children, and those with inadequate lip coverage, overbite, or overjet are more likely to have TDI in the primary dentition.

BACKGROUND
Relationships between malocclusion and orofacial myofunctional disorders (OMD), as well as malocclusions and articulation disorders (AD) have been described, though the exact relationships remain unclear. Given the high prevalence of these disorders in children, more clarity is needed.
SUMMARY
The purpose of this study was to determine the association between OMD (specifically, bruxism, deviate swallowing, caudal resting tongue posture, and biting habits), AD, and malocclusions in children and adolescents aged between 3 and 18 years. To conduct a systematic review, 4 databases were searched (MEDLINE, Embase, Web of Science, and Scopus). The identified articles were screened for the eligibility criteria. Data were extracted from the selected articles and quality assessment was performed using the tool of Munn et al. [Int J Health Policy Manag. 2014;3:123-81] in consensus. Using the search strategy, the authors identified 2,652 articles after the removal of duplicates. After reviewing the eligibility criteria, 17 articles were included in this study. One of the included articles was deemed to have an unclear risk of bias, whereas all other articles were considered to have a low risk of bias. The articles showed a relationship between anterior open bite and apico-alveolar articulatory distortions, as well as between anterior open bite and deviate swallowing. For the biting habits, bruxism, and low tongue position no clear conclusions could be drawn. Key Messages: The current review suggests a link between specific types of malocclusion and OMD and AD. However, more high-quality evidence (level 1 and level 2, Oxford Levels of Evidence) is needed to clarify the cooccurrence of other OMD, AD, and malocclusions.

Review
Cri du chat syndrome is an autosomal disorder. Because it affects few people in the population it is considered a rare disease, yet it is one of the most common autosomal chromosomal syndromes in humans. It entails pathognomonic alterations that affect the craniofacial and oral anatomy of patients. The aim of this study is to review these craniofacial and oral abnormalities in patients with Cri du chat syndrome. The PubMed Medline database was searched using two different strategies. First, we used "Dentistry" and "Cri du chat" as keywords; second, we used "Cri du chat" and "craniofacial." Seven articles in which the main orofacial and cranio-skeletal characteristics of patients with Cri du chat syndrome were described were selected according to the inclusion and exclusion criteria. Cri du Chat syndrome entails pathognomonic characteristics in the craniofacial area (epicanthus, short philtrum, and wide nasal bridge), the oral area (mandibular retrognathism and anterior open bite) and the cranial region (alterations at the cranial base angle and a small upper airway). However, more studies on larger samples are needed to specify the orofacial and craniofacial characteristics of patients with Cri du chat syndrome more accurately. Clin.

Meta-Analysis
BACKGROUND
Several orthognathic procedures have been applied to correct skeletal anterior open bites (SAOB). Which method is most stable has been debated and no consensus has been reached and there is no conclusive evidence for clinicians to use.
OBJECTIVE
To analyse whether maxillary, mandibular, or bimaxillary surgery provides a better stability.
MATERIALS AND METHODS
A systematic search was conducted up to December 2020 using PubMed, EMBASE, Medline, Scopus, Web of Science, Cochrane CENTRAL, and Google Scholar. We made direct comparisons among the controlled trials and also made indirect comparisons via subgroup analysis on the aspects of occlusional, skeletal, and dento-alveolar stability to assess the overall stability of each method.
RESULTS
Finally 16 cohort studies were identified. At the occlusional level, pooled change in overbite was 0.21 mm in maxillary surgery, 0.37 mm in bimaxillary surgery, and -0.32 mm in mandibular surgery. At the skeletal level, pooled sella-nasion-Point A angle (SNA) was -0.12 degrees in bimaxillary surgery, -0.37 degrees in maxillary surgery and -0.20 degrees in mandibular surgery. The sella-nasion to palatal plane angle (SNPP) relapsed to a statistically significant degree in all samples received single maxillary surgery. Relapse of the sella-nasion-Point B angle (SNB) was 0.47 degrees in mandibular setback, -1.8 degrees in mandibular advancement, and -0.48 degrees in maxillary surgery. The Sella-Nasion to mandibular plane angle (SNMP) relapsed more in procedures involving bilateral sagittal split osteotomy than in other procedures. As for dento-alveolar changes, intrusion of molars and extrusion of incisors took place in most patients.
CONCLUSIONS
Bimaxillary surgery produced the most beneficial post-operative increase in overbite, maxillary surgery led to a lesser but still positive overbite change, and mandibular surgery correlated with some extent of relapse. Skeletally, bimaxillary surgery was more stable than maxillary surgery at both SNA and SNPP; SNB was more stable in mandibular setback than advancement; and SNMP was unstable in both mandibular and bimaxillary surgeries versus maxillary surgery with comparable surgical changes. Dento-alveolar compensation helped maintain a positive overbite.

Dental Press Journal of Orthodontics 2023This systematic review aims to answer the following focus question: "Is there an association between atypical swallowing and malocclusions?".
OBJECTIVE
This systematic review aims to answer the following focus question: "Is there an association between atypical swallowing and malocclusions?".
METHODS
Appropriate word combinations were chosen and tailored specifically for each of the following electronic databases: EMBASE, Latin American and Caribbean Literature in Health Sciences (LILACS), LIVIVO, PubMed/Medline, Scopus, Web of Science, and gray literature, without any restrictions, up to February 2021. According to the selection criteria, only cross-sectional studies were included. The following inclusion criteria were considered: a sample composed of children, adolescents, and adults; patients clinically diagnosed with atypical swallowing; patients with normal swallowing; and outcome of interest of atypical swallowing in patients with malocclusion. The data consisted of study characteristics, sample characteristics, results, and conclusion of each study. The risk of bias was assessed using the JBI Critical Appraisal Checklist for Analytical Cross-Sectional Studies, and the certainty of evidence was assessed using the GRADE tool.
RESULTS
4,750 articles were identified. After a two-step selection, four studies were included. A higher frequency of distal occlusion, extreme maxillary overhang, and open bite was related to swallowing disorders; most studies pointed to posterior crossbite as a malocclusion more associated with atypical swallowing. All studies had a moderate to high risk of bias, and the certainty of evidence was very low.
CONCLUSION
The results indicate that atypical swallowing is associated with malocclusions and that posterior crossbite is the main malocclusion found, but only in the young population (3-11 years).

Meta-Analysis Review
BACKGROUND
Researchers have purported that breast-feeding can decrease the risk of malocclusions. The authors studied the relationship of breast-feeding on malocclusions in young children by means of conducting a systematic review of association (etiology).
TYPES OF STUDIES REVIEWED
The authors used a 3-step search strategy, including electronic searches. They considered studies whose investigators included healthy children with primary dentition with a history of breast-feeding and in which the study investigators had assessed specific malocclusion outcomes to be eligible for inclusion in this review. The authors considered prospective and retrospective (longitudinal) studies, case-control studies, and analytical cross-sectional studies. Two of the authors, using standardized instruments, independently assessed the methodological quality and extracted data from the included studies. For situations for which there were a sufficient number of studies, the authors conducted meta-analyses using the random-effects model, supplemented with the fixed-effects model in situations for which statistical heterogeneity was 50% or less, assessed using the I statistic.
RESULTS
The authors identified 7 studies that were included in the review. They found that children who had breast-fed suboptimally had an increased risk of developing malocclusions and that a strong and significant association existed between a shorter duration of breast-feeding (less than 12 months) and the development of an anterior open bite (n = 1,875; risk ratio, 3.58; 95% confidence interval, 2.55 to 5.03; P < .00001) and a class II canine relationship (n = 1,203; risk ratio, 1.65; 95% confidence interval, 1.38 to 1.97; P < .00001).
CONCLUSIONS
Young children with a history of suboptimal breast-feeding have a higher prevalence and risk ratio for malocclusions. These children have an increased risk of developing a class II canine relationship, posterior crossbite, and anterior open bite.
PRACTICAL IMPLICATIONS
Dental health care professionals should continue to encourage and promote breast-feeding; however, patients should be aware that children still can develop malocclusions, despite having received optimal breast-feeding, owing to the multifactorial etiology of malocclusions.

BMC Oral Health Aug 2022To estimate the prevalence of malocclusion in individuals with autism spectrum disorders (ASD) and to assess the relationship between ASD and malocclusion. (Meta-Analysis)
Meta-Analysis
BACKGROUND
To estimate the prevalence of malocclusion in individuals with autism spectrum disorders (ASD) and to assess the relationship between ASD and malocclusion.
METHODS
We searched electronic databases including PubMed, Scopus, Web of Science, Cochrane, Embase, SciELO LILACS, Proquest, OpenGrey and Google Scholar. There were no language or publication dates restrictions. Two researchers independently performed selection, data extraction and quality assessment. Quality assessment and risk of bias were evaluated through the Newcastle-Ottawa scale and ROBINS-E tool. Meta-analyses using random effect models were used to estimate pooled measures of prevalence of malocclusion characteristics in individuals with ASD and pooled odds ratio (OR) on the relationship between ASD and malocclusion characteristics. Subgroup meta-analyses were conducted according to children and adolescents, history of orthodontic treatment, and occurrence of other syndromes and medical conditions.
RESULTS
Searching identified 5549 papers with 238 were selected for full assessment. Eighteen cross-sectional studies were included according to inclusion criteria. Of them, eleven studies were considered of moderate quality. A judgement of critical risk of bias occurred for thirteen studies. The most prevalent malocclusion characteristics in individuals with ASD were crowding (33%; 95% CI 22 to 44%) and increased maxillary overjet (39%; 95% CI 23 to 54%). Individuals with ASD had higher odds of Angle's Class II (OR 1.92; 95% CI 1.36 to 2.72), Angle's Class III (OR 2.33; 95% CI 1.29 to 4.23), open bite (OR 1.96; 95% CI 1.21 to 3.16), and increased maxillary overjet (OR 1.53; 95% CI 1.06 to 2.21) than individuals without ASD.
CONCLUSIONS
Angle's Class II, Angle's Class III, anterior open bite and increased maxillary overjet were more prevalent in individuals with ASD than those without ASD. Further high-quality studies are needed.
