Chen H, Lin L, Chen J, Huang F. Prevalence of Malocclusion Traits in Primary Dentition, 2010-2024: A Systematic Review. Healthcare (Basel) 2024; 12:1321. [PMID: 38998856 PMCID: PMC11241413 DOI: 10.3390/healthcare12131321] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2024] [Revised: 06/23/2024] [Accepted: 06/28/2024] [Indexed: 07/14/2024] Open
Abstract
The present review was aimed to describe the prevalence and the regional distribution of malocclusion among preschool children worldwide. Two independent reviewers performed a systematic literature search to identify English publications from January 2010 to May 2024 using PubMed, ISI Web of Science and Embase. Search MeSH key words were "malocclusion", "primary dentition" and "child, preschool". The reporting quality was assessed by the modified Newcastle-Ottawa Quality Assessment Scale. We identified 2599 publications and recruited 47 articles. Fourteen of the included studies were conducted in Asia, four in Europe, twenty-eight in South America and one in Africa. The prevalence of malocclusion ranged from 28.4% to 83.9%, and half of the reported prevalences were higher than 50%. The highest percentage was in Asia (61.81%), followed by Europe (61.50%), South America (52.69%) and Africa (32.50%). Statistically significant differences existed in deep overbite, anterior open bite, posterior crossbite, edge-to-edge incisor relationship and distal step between continents (p < 0.05). Europe showed the highest prevalence (33.08%) of deep overbite. Africa showed the highest prevalence (18.60%) of anterior open bite. Europe showed the highest prevalence (15.38%) of posterior crossbite. The most common malocclusion traits were increased overjet and deep overbite. To conclude, malocclusion remained prevalent in the primary dentition and varied between countries.

Effects of autologous concentrated growth factor on gingival thickness in periodontal accelerated osteogenic orthodontics: a 6-month randomized controlled trial. BMC Oral Health 2021; 21:604. [PMID: 34814921 PMCID: PMC8609726 DOI: 10.1186/s12903-021-01967-5] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2021] [Accepted: 11/10/2021] [Indexed: 12/22/2022] Open
Abstract
Background Earlier studies have not given clear results of concentrated growth factor (CGF) on gingival thickness (GT) in periodontal accelerated osteogenic orthodontics (PAOO). This randomized controlled trial aimed to evaluate the effects of CGF on GT in patients with thin gingival phenotype undergoing PAOO. Methods Forty four patients presenting 264 anterior mandibular teeth were recruited and randomly allocated to one of the groups: test—positioning of autologous CGF after PAOO or control—positioning of a collagen membrane after PAOO. GT, gingival height (GH), buccal alveolar bone thickness (BT), and buccal alveolar bone height (BH) were evaluated depending on cross-sectional CBCT images at t0 (before surgery) and t1(6 months after surgery). Results GT were increased in both groups at t1 compared to t0. Yet, higher values were observed in the test group (from 0.94 ± 0.23 to 1.31 ± 0.33 mm) compared to the control group (from 0.94 ± 0.19 to 1.02 ± 0.16 mm) (p < 0.05). Moreover, in the intergroup comparison, GT at t1 in the test group was significantly higher compared to the control group (p < 0.01). Furthermore, the GT of central incisors, lateral incisors and canine teeth all showed significantly changes compared with baseline and the test group showed higher increase (p < 0.01). No statistically significant difference were found in GH, BT, BH and all clinical parameters between two groups at t1 (p > 0.05). Conclusions Within the limitation of this study, gingival thickness could be increased by using CGF in PAOO for the patients with thin gingival phenotype. Trial registration The study was registered in Chinese Clinical Trial Registry (http://www.chictr.org.cn/index.aspx) under the number ChiCTRINR17013346, Registered 11 November 2017. Supplementary Information The online version contains supplementary material available at 10.1186/s12903-021-01967-5.

Abstract
Complex craniofacial deformities such as complete bilateral cleft lip and palate require interdisciplinary approach for proper diagnosis and treatment. A severe skeletal discrepancy caused by bilateral cleft lip and palate and missing premaxilla was successfully managed with orthodontic preparation and distraction osteogenesis. Conventional prosthodontic treatment combined with orthodontic preparation was proven to be a viable option to manage multiple missing teeth in cleft lip and palate.

Abstract
Introduction: The cleft lip and palate is the most frequent craniofacial anomaly and as a consequence of this malformation some inadequate occlusal relationship between the arches are observed. Furthermore, dental absences, individual positioning changes of teeth as rotations, and in more rare situations the transpositions may be found as well. Description: In this context, in this article is reported a case of a 9-year-old patient with unilateral cleft lip and palate, with anterior and posterior crossbite on the left side, absence of the maxillary left lateral incisor, and transposition of the maxillary left canine and first premolar. The patient was treated with slow maxillary expansion, secondary graft and fixed orthodontic appliance, transposition maintenance and closing of the lateral incisor space with the first premolar, by means of mesialization of the posterior teeth. Results: At the end of the treatment, good intercuspation and an important aesthetic gain for the patient were achieved. The analysis three years after treatment revealed a good stability of the results obtained.

Comparison of Three-Dimensional and Conventional Orthodontic Imaging Modalities for Localization of Impacted Maxillary Canines in Patients With Alveolar Cleft. Cleft Palate Craniofac J 2020; 58:202-207.

Abstract
OBJECTIVE The purpose of this study was to identify which diagnostic parameters related to impacted maxillary canines can be reliably detected by the conventional orthodontic radiographic modalities and which factors need to be assessed by cone-beam computed tomography (CBCT). DESIGN In this cross-sectional study, 8 orthodontists evaluated 7 parameters related to the position and anatomy of the impacted canines by means of 2-dimensional (2D) records. After 1 month, the same process was repeated by means of CBCT by the same clinicians. SETTING Qazvin University of Medical Sciences. PATIENTS AND PARTICIPANTS Thirty-two patients with alveolar cleft and impacted maxillary canines who had CBCT scans, lateral cephalograms, and orthopantomographs as pretreatment records. MAIN OUTCOME MEASURE The diagnostic accuracy of 2D and 3-dimensional (3D) radiographic modalities was compared with each other and also with the gold standard by 3 radiologists. RESULTS The diagnostic accuracy of 2D and 3D imaging modalities was not significantly different regarding the mesiodistal inclination of the impacted tooth (P = .09), apex anatomy (P = .10), and mesiodistal position of the apex (P = .19). Cone-beam computed tomography had significantly higher diagnostic accuracy than conventional radiographic modalities regarding overlapping the adjacent tooth (P = .001), labio-palatal and apico-coronal position of the crown tip, and root resorption of the adjacent tooth (P = .01). CONCLUSION The conventional orthodontic radiographic modalities were as accurate as CBCT for determination of impacted canine inclination, apex anatomy, and mesiodistal position of the apex. Cone-beam computed tomography showed higher diagnostic accuracy for other parameters.

Abstract
: The bilateral cleft lip (BCL) is the most severe manifestation of orofacial clefts. Multiple techniques have been described to reconstruct BCL to obtain good aesthetic and functional results with minimal complications. OBJECTIVE Description of surgical technique for BCL reconstruction and present the postoperative results obtained. METHODS Patients with BCL of the cleft lip and palate at ABC Medical Center from June 2013 to June 2017 operated with Mendoza bilateral cheiloplasty were included. The procedure includes an anatomical reconstruction of the lip with minimal resection of tissue, alignment of the orbicularis muscle, vestibule creation, and complete use of the prolabium. The evaluation was carried out by photographs analyzing parameters of quality, symmetry, and alignment of lip and nose structures. RESULTS The authors included 36 patients, 15 women and 16 men. The average procedure time was 57 minutes. Photographs were evaluated 1 year postoperatively, symmetry in lip was observed in 91.6% of the patients, muscle continuity in 100%, deep gingivolabial sulcus in 94.5% of cases, closed nasal floor in 100% with no presence of nasovestibular fistulas. CONCLUSIONS This technique allows an anatomical BCL reconstruction with good aesthetic and functional results.

Abstract
PURPOSE This study aimed to assess body posture before and after bimaxillary orthognathic surgery by photogrammetry in skeletal class III patients. METHODS Thirty-one patients with skeletal class III dentofacial deformities (14 men, 17 women) who underwent orthodontic preparation for surgery were included in this non-randomized controlled trial. Of these, 15 who did not undergo orthognathic surgery during the period of this study served as controls. Postural assessment was performed by photogrammetry using SAPO® (Postural Assessment Software) based on anterior-, posterior-, and lateral-view images taken 1 month before and 4 months after bimaxillary orthognathic surgery with internal rigid fixation (or 4 months after the initial assessment, for the control group). The study was approved by PUCRS Research Ethics Committee, and written informed consent was obtained from all individual participants prior to their inclusion in the study. RESULTS There was no significant difference between groups for age, gender, and GAP. In the intervention group, the right leg/hindfoot angle, which initially indicated a valgus deformity, normalized after intervention (P < 0.048). Posterior displacement of the head (P < 0.005) and trunk (P < 0.004) were observed after intervention. CONCLUSIONS These results suggest that correction of class III dentofacial deformities by bimaxillary orthognathic surgery can produce systemic postural adjustments, especially posterior displacement of the head and trunk and knee and ankle valgus.
