Review
Odontoplasty (floating and occlusal equilibration) is the most commonly performed procedure in equine dentistry. From an anatomic perspective, an irregular occlusal surface, prominent cingula, transverse ridges, and enamel points all contribute to the function, form, and longevity of the equine cheek tooth. With limited reserve crown available and an average functional life range between 18 and 25 years, removal of tooth structure should be conservative. The authors consider a quality oral examination to be the most important dental procedure performed in the horse. Individual tooth evaluation should lead to a specific diagnosis and treatment plan. Tooth odontoplasty should be site-specific.

Review
Although all dentofacial deformities involve deviation of skeletal and dental units that require correction, the timing and method of treatment can vary considerably. Growth is a key consideration when managing dentofacial deformities, because it has a direct impact on the timing and method of management. Some deformities may be intercepted and managed during growth, whereas others can only be definitively managed after cessation of growth. This article focuses on clinical considerations of growth in managing dentofacial deformities, and discusses methods of growth evaluation and interceptive orthodontic management strategies in different types of dentofacial deformities.

Meta-Analysis Review
BACKGROUND
Ankyloglossia is a congenital alteration that affects the tongue's mobility, influencing craniofacial development; however, its association with malocclusion is still unclear. This systematic review and meta-analysis investigated the association between ankyloglossia and malocclusion in patients.
TYPES OF STUDIES REVIEWED
The authors conducted a systematic review and meta-analysis of observational studies that investigated the association between malocclusion and the presence of ankyloglossia in any age group, used any assessment tool to diagnose ankyloglossia, and considered all types of malocclusion. The authors conducted searches in 8 electronic databases through July 1, 2022. They used Joanna Briggs Institute appraisal tools to assess the methodological quality and the Grading of Recommendations, Assessment, Development and Evaluations approach to assess the certainty of the evidence.
RESULTS
Eleven studies (5 cross-sectional, 6 case-control) included 2,904 patients and over 13 occlusal alterations. The certainty of the evidence ranged from low through very low. Patients with Angle Class III malocclusion had similar or more inserted lingual frenula than patients with Class I malocclusion (standard mean difference, 0.37; 95% CI, -0.50 to 1.25) and Class II malocclusion (standard mean difference, 0.55; 95% CI, -0.52 to 1.63). Patients with Class III malocclusion had clinically significant increased mouth opening reduction compared with patients with Class I malocclusion (mean difference, 6.67; 95% CI, 4.01 to 9.33) and Class II malocclusion (mean difference, 5.04; 95% CI, 2.35 to 7.72) patients.
PRACTICAL IMPLICATIONS
There is uncertain evidence that ankyloglossia may be associated with the development of occlusal alterations. Ankyloglossia did not influence the Angle classification. Clinicians should closely follow children with ankyloglossia to evaluate whether this condition interferes with the occlusion. Future research should prospectively follow up on the long-term association between ankyloglossia and malocclusion. The protocol was registered a priori in the PROSPERO database (CRD42021248034). No amendments were deemed necessary after the registration of the protocol. Some subgroup analyses planned a priori were not possible, such as the severity of ankyloglossia, sex, and age, due to the lack of studies reporting data for these subgroups.

Meta-Analysis Review
OBJECTIVES
The aim of this article is to establish a comprehensive nationwide prevalence of malocclusion traits on the sagittal, vertical, and transverse planes of space in the Turkish population.
MATERIAL AND METHODS
A systematic search of PubMed, Scopus, and Web of Science was supplemented by manual searches of Google Scholar and the reference lists of included studies. Original Turkish health studies of any age were included. Strengthening the Reporting of Observational Studies in Epidemiology assessed study quality and bias (STROBE). Sagittal, vertical, and transverse malocclusion features were retrieved and gathered.
RESULTS
Eleven studies were selected from 434 titles. Two studies showed a high risk of bias, eight low and one moderate. Thirteen thousand two hundred seventy-one individuals were investigated from early childhood to late adulthood. Most studies were sampled from universities and dental (nonorthodontic) clinics. The pooled malocclusion prevalence was 56% for Class I (95% confidence interval (CI): 44-68%), 31% for Class II (CI: 6-42%), and 11% for Class III (CI: 21-37%). The other common types of malocclusions were crowding (41%, CI: 18-65%), overjet (34%, CI: 21-50%), negative overjet (13%, CI: 7-20%), and crossbite (11%, CI: 7-15%). Additionally, there was no significant difference in Class I (relative risk [RR] = 1.00, [0.96-1.05]), Class II ([RR] = 0.97, [0.92-1.03]), and Class III ([RR] = 1.08, [0.96-1.225]) malocclusion by gender.
CONCLUSIONS
This study showed Class I malocclusion has a high prevalence among the Turkish population followed by Class II and Class III malocclusions. In addition, crowding and overjet were the most prevalent malocclusions among Turkish individuals. There were no significant differences in the prevalence of malocclusions between males and females.

Review
OBJECTIVE
To identify the association of occlusal disorders in patients with sickle cell disease (SCD).
STUDY DESIGN
A literature review was conducted, and articles published between 2010 and 2019 were searched on Bireme and PubMed websites and in MEDLINE and LILACS databases, in English, Portuguese, and Spanish, using the keywords "malocclusion," "sickle cell disease," and "cephalometry," combined by Boolean operators AND and OR. One of the criteria for the selection of articles was the presence of adolescents in the sample. This methodology followed the PRISMA recommendations. Seventy-nine articles were found, seven of which were included in the review as they met the inclusion criteria and the study goals.
RESULTS
The prevalence of malocclusion in SCD patients ranged from 62.9% to 100%, which was considered very severe in 30.1% to 80.6%. The most common occlusal changes were Angle's class II malocclusion, increased maxillary overjet, and anterior open bite. In addition, class II skeletal pattern was the most prevalent due to mandibular retrusion.
CONCLUSION
Malocclusion prevalence in SCD patients is high and considered to be a risk factor, with a significant rate of very severe malocclusion when compared to healthy patients.

Review
AIM
This review intends to highlight malocclusion as a multifactorial issue and review the different factors that influence different types of malocclusion and arch form.
METHODS
An online article search was performed on the factors influencing malocclusion and arch form from January 1990 through April 2020. The search was performed within the Google, Rutgers library, PubMed, MEDLINE databases via OVID using the keywords mentioned in the PubMed and MeSH headings for the English language published articles January 1990 through April 2020, which evaluated different factors that influence malocclusion and arch form.
RESULTS
Of the 300 articles found in initial search results, 31 articles met the inclusion criteria set for this review. These 31 studies were directly related to the factors that impact malocclusion and different arch forms.
CONCLUSION
Genetic inheritance, genetic mutations, age, gender, ethnicity, dental anomalies like macrodontia, congenital diseases, muscular diseases, hormone imbalance, and human behaviour are all factors that influence malocclusion and arch forms. The elements within the individual's control like behaviours can aid in preventing malocclusion. However, it seems as if the underlying reason for most of these factors indicates that malocclusion is a by-product of genetics and pathology.

OBJECTIVES
To evaluate the relationship between dental malocclusion and speech to understand the etiology of speech sound disorders (SSD) in schoolchildren and to make a correct diagnosis and treatment plan.
MATERIALS AND METHODS
Articulation and dental occlusion, oromyofunctional evaluation with orofacial praxis and musculature, resting tongue position, and swallowing pattern were analyzed in 290 schoolchildren between the ages of 4 and 7 years. Statistical tests were considered significant for P < .05.
RESULTS
A significant association between dental malocclusions (Angle Class II and III, anterior open bite, edge-to-edge bite, overjet and anterior crossbite) and phonetic alterations (P = .008) was observed. Sigmatisms and rhotacisms were the most frequent disorders. Malocclusions also showed a significant association with oral habits and with orofacial praxis and muscle activity.
CONCLUSIONS
The presence of malocclusion can cause imbalances in the functions involved in the stomatognathic system. Awareness of this relationship in young children would help professionals to implement preventive measures for the optimum development of children's oral health.

INTRODUCTION
Orthodontic diagnosis is generally centered on the morphological aspect, as is the treatment: it is most often a matter of modifying the shape of the arches and their relationships to adjust them to a morphological norm with the goal of a beautiful smile. However legitimate it may be, this diagnostic approach may seem reductive if we consider that teeth are also used to chew: it is even their main function. But how to take into account the masticatory function?
MATERIALS AND METHODS
With the help of clinical examples, the author develops the modalities of the clinical exploration of the mandibular kinematics, reflection of the mastication, on which the systemic diagnosis is based. It highlights the proprioceptive resources of the masticatory system that systemic treatment targets during the correction of malocclusions.
CONCLUSION
The systemic diagnosis highlights the functional role of the arches, inviting, during their correction, to rehabilitate mastication in order to improve their stability.

Review
OBJECTIVES
The multifactorial aspect of malocclusions and their consequences on ingestion function is rarely described in the literature. The aims of this review are (i) to investigate the relationship between oral ingestion and malocclusion and (ii) to gather malocclusion tools that could help screen subjects at risk of malocclusion-related ingestion disorders.
MATERIAL AND METHODS
A systematic review was performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocol (PRISMA-P 2015) guidelines. The analysis methods and inclusion criteria have been documented in a protocol published in the Prospective International Register of Systematic Reviews (PROSPERO) under the registration number CRD42023395840. The bibliographic search involved the PubMed®, Cochrane and PROSPERO databases.
RESULTS
A total of 29 articles published between 2007 and 2023 were retained by the search criteria for the qualitative synthesis. Twenty of the studies found that the severity of malocclusion has a negative impact on oral ingestion. This review highlights that malocclusion and ingestion impairments are associated but it is not possible to determine causality due to the observational approach of many of the studies.
CONCLUSION
Malocclusion has a negative impact on ingestion function. During orthodontic consultations, particular interest should be directed towards chewing, biting, and swallowing disorders, which can affect patients' nutritional status. This review offers arguments for designing further studies assessing the extent to which malocclusions may affect nutritional status.
CLINICAL RELEVANCE
Orthodontic treatment should focus on improving patients' ingestion.
