RESUMEN

BACKGROUND: Although several researchers have analyzed the dental identity of patients experience with corrective methods using fixed and removable appliances, the consequences stay debatable. This meta-analysis intended to verify whether the periodontal status of removable appliances is similar to that of the conventional fixed appliances. METHODS: Relevant literature was retrieved from the database of Cochrane library, PubMed, EMBASE, and CNKI until December 2019, without time or language restrictions. Comparative clinical studies assessing periodontal conditions between removable appliances and fixed appliances were included for analysis. The data was analyzed using the Stata 12.0 software. RESULTS: A total of 13 articles involving 598 subjects were selected for this meta-analysis. We found that the plaque index (PLI) identity of the removable appliances group was significantly lower compared to the fixed appliances group at 3 months (OR = -0.57, 95% CI: -0.98 to -0.16, P = .006) and 6 months (OR = -1.10, 95% CI: -1.60 to -0.61, P = .000). The gingival index (GI) of the removable appliances group was lower at 6 months (OR = -1.14, 95% CI: -1.95 to -0.34, P = .005), but the difference was not statistically significant at 3 months (OR = -0.20, 95% CI: -0.50 to 0.10, P = .185) when compared with that of the fixed appliances group. The sulcus probing depth (SPD) of the removable appliances group was lower compared to the fixed appliances group at 3 months (OR = -0.26, 95% CI: -0.52 to -0.01, P = .047) and 6 months (OR = -0.42, 95% CI: -0.83 to -0.01, P = .045). The shape of the funnel plot was symmetrical, indicating no obvious publication bias in the Begg test (P = .174); the Egger test also indicated no obvious publication bias (P = .1). CONCLUSION: Our meta-analysis demonstrated that malocclusion patients treated with the removable appliances demonstrated a better periodontal status as compared with those treated with fixed orthodontic appliances. However, the analyses of more numbers of clinical trials are warranted to confirm this conclusion.

RESUMEN

Since 1907, the international community has used Angle's classification to assess the mesio-distal relationships of the dental arches. It is the basis of the diagnosis of malocclusion in the sagittal dimension and indicates or not an orthodontic correction treatment. This work was aimed to inventory the classification methods of malocclusions used today. Indices of treatment need were also presented because they are based on one or more occlusal anomalies to indicate treatment. The classifications were criticized and the contribution of a functional analysis based on the use of the trilogy setting, centering and guiding was detailed. The type of anomalies (skeletal and dental) must be completed by the analysis of the occlusal anomaly of setting (centering or guiding) and of the category of occlusion (functional occlusion, functional malocclusion or pathogenic malocclusion), ie its possible pathogenic impact on orofacial structures. A consensus on the classification of occlusal anomalies is necessary in order to better identify the anomalies and their global repercussions, and to better define the needs for orthodontic treatment.

RESUMEN

Las compresiones del maxilar superior son alteraciones transversales por discrepancia óseo-dentaria. .En la dentición mixta temprana puede establecerse la estrechez mediante índices que relacionan el tamaño dental con el ancho transversal del arco dentario. Se analizaron 33 modelos superiores de niños en el tercer período de desarrollo clínico según Barnett. Se estableció la estrechez realizando el análisis métrico del arco dental mediante el índice de Pont. Se describió la anomalía de posición anterior según las siguientes variables: A) Apiñamiento dentario: 1-Escalón de los dientes anterosuperiores; 2-Rotación mesial de los cuatro incisivos; 3-Rotación mesial de los incisivos centrales y rotación distal de los incisivos laterales y 4-Rotación distal de los incisivos centrales. B) Ausencia de apiñamiento: 1-Reabsorción atípica y 2- Ausencia de reabsorción atípica. Las anomalías de posición y/o reabsorciones atípicas anteriores en este período de desarrollo clínico se asocian a estrechez transversal del maxilar superior Siendo la malposición más frecuente la rotación mesial de los cuatro incisivos, siguiendo las reabsorciones atípicas y el escalón de los dientes anterosuperiores, luego la rotación mesial de los incisivos centrales y distal de los laterales y por último la rotación distal de los incisivos centrales (AU)


Inside the traverse alteration of the maxillary the compressions are described as uni or bilateral where an imbalance is settled down between the dental size and the size of the maxillary causing alterations in the position of the teeth. In the early mixed teething the narrowness of the maxillary can be settled by means of indexes that relate the dental size with the traverse width of the dental arch. Thirty models of the maxillary of children according to Barnett's third development period were analyzed. The metrical analysis of the dental arch form was carried out through Pont's index. The theoretic values were compared with the real ones establishing the deviations of the norm that is to say the narrow nest. Out of the 30 cases analyzed, 40% presented mesial rotation of the 4 incisors; 27% showed a stop of the front teeth; 27% atypical reabsorption; 20% mesial rotation of the central incisors and distal rotation of the lateral incisors and the 10% presented a distal rotation of the central incisors. With regard to the front atypical discrepancy 36.66% of the cases had a discrepancy above 6 mm and the 23.33% below 3 mm (AU)

RESUMEN

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.

RESUMEN

PURPOSE: Socioeconomic inequalities are recognized as a major problem with people in low socioeconomic groups having worse subjective oral health outcomes, including oral health-related quality of life (OHRQoL). However, only a few longitudinal studies assessed the impact of contextual and individual socioeconomic determinants in adolescents' OHRQoL. We estimate the impact of socioeconomic inequalities on adolescents' OHRQoL over a 2-year period. METHODS: This study followed up a random sample of 1134 12-year-old schoolchildren for 2 years in Brazil. OHRQoL was assessed by the Brazilian version of the Child Perceptions Questionnaire for 11- to 14-year-old Children (CPQ11-14) at baseline and follow-up. Participants were clinically examined for dental caries, gingival bleeding, and malocclusion. The schoolchildren's parents answered a questionnaire regarding socioeconomic status, social capital, and adolescents' use of dental service. Socioeconomic contextual variables were collected from official city publications. Multilevel linear regression models fitted the associations between socioeconomic factors and overall CPQ11-14 scores over time. RESULTS: A total of 747, 14-year-old adolescents were reassessed for OHRQoL (follow-up rate of 66%). Adolescents with lower mean income school's neighborhood (P < 0.05), household income (P < 0.05), and maternal schooling (P < 0.05) had higher overall CPQ11-14 scores. Female sex, attending a dentist by toothache, dental caries, and malocclusion were also associated with higher overall CPQ11-14 scores. CONCLUSIONS: Adolescents from low socioeconomic background reported worse OHRQoL at 2-year follow-up compared to those from high socioeconomic background. Actions toward health inequalities need to address socioeconomic factors in adolescence.

RESUMEN

Facial asymmetry is a common complaint in patients with facial concerns. Some patients have mandibular asymmetries that have light maxillary cant compensation due to a reduced gingival exposure. A common treatment in facial asymmetries is bimaxillary surgery treatment. However, there are no cases of non-severe occlusal plane canting (OPC) with mandibular asymmetry treated with mandibular surgery and miniscrews for the extrusion of the maxillary molars. The aim of this article is to show how to correct mandibular asymmetries combined with OPC by making a single mandibular "early surgery" combined with the extrusion of the maxilla with miniscrews to correct the occlusal plane in order to avoid a Le Fort I surgery. This type of treatment provides lower medical costs, shorter surgeries, and less postoperative discomfort and invasion for patients.

RESUMEN

INTRODUCTION: Obstructive adenoid hypertrophy is cited as one of the causes of mouth breathing and leads to disharmony in the development of orofacial structures. The objective of this study was to compare the measurements of dental arches according to the grade and the obstructive character of adenoids. MATERIALS AND METHODS: A cross-sectional study was carried out with 86 children. The grade and the obstructive character of adenoids were determined from Holmberg and Cohen's radiographic methods respectively. Dental arch measurements were taken on dental casts. A t-test and a Chi2 test were performed respectively to compare the quantitative and qualitative variables of dental arches according to the obstructive character. An Anova test made it possible to compare the quantitative variables according to the grade as Holmberg defined it. For variables that showed significant differences, a Post Hoc test was used. The significance level was set at P=0.05. RESULTS: Subjects with obstructive adenoids had a shorter posterior mandibular length (P=0.04) and a greater overbite (P=0.04) than those with non-obstructive adenoids. Those with grade 4 had a greater arch depth (P=0.02) and were more prone to open bite(P=0.03). CONCLUSION: A prevention program involving the otorhinolaryngologist and the orthodontist for subjects with obstructive adenoids or grade 4 is necessary to minimize their influence on dental arch relationships.

RESUMEN

Dental and stomatologic problems in childhood need to be diagnosed and managed with multidisciplinary protocols focusing around the children an appropriate prevention, diagnosis, and care program. Therefore, it is paramount to avail of screening tools that provide an indication of in-depth multidisciplinary diagnostic flow. The aim of this study is to detect and evaluate malocclusion problems and predisposing factors in an Italian preschooler population. Design-calibrated operators detected data through examination of 1,405 children (706 males and 699 females) aged between 2 and 7 years, in one hospital in Rome and in kindergartens of several Italian cities. Data were collected following Risk of Malocclusion Assessment index criteria. Pearson's chi-square test (with continuity correction) and Fisher's exact test were the statistical tests conducted (P < 0.05). Grade 2 (49.6%) and 4 (21.7%), followed by grade 1 (17.1%), grade 3 (9.3%), and finally grade 5 (2.3%) are the most represented degrees. 53.6% of the cases have a high risk, whereas 32.2% has a low risk and 14.9% has a moderate risk. The risk-degree correlation is statistically significant (P < 0.005). Flawed habits and oral breathing are present in more than a quarter of children. Findings of the study highlighted that early multidisciplinary approach, as well as orthodontic visits and screening in childhood, is necessary to promote normal growth and development of the face and the elimination of potential interferences that may harm these processes.

RESUMEN

As maloclusões são classificadas como o terceiro maior problema de saúde bucal no mundo, perdendo apenas para cárie e doença periodontal. A mordida cruzada posterior é definida como a relação anormal vestíbulo-lingual de um ou mais dentes da maxila, com um ou mais dentes da mandíbula, quando os arcos dentários estão em relação cêntrica, podendo ser uni ou bilateral. Objetiva-se Realizar uma revisão de literatura sobre a mordida cruzada posterior. Foi feita uma seleção de artigos científicos a partir das bases de dados Lilacs e Scielo utilizando os descritores "Mordida Cruzada" e "Diagnóstico de Mordida Cruzada". Foram incluídos trabalhos publicados entre 2000 a 2018. Dos 694 artigos encontrados e delimitados pelos critérios inclusivos, foram selecionados 49 artigos como amostra, que apresentaram a temática elencada para a pesquisa e que foram discutidos nos seguintes tópicos: a) Epidemiologia; b) Etiologia; c) Diagnóstico; d) Tratamento. As causas da mordida cruzada posterior são multifatoriais e seu diagnóstico precoce é fundamental uma vez que, a literatura mostra resultados satisfatórios, através de medidas interceptativas com um prognostico favorável quando o tratamento ocorre precocemente. O tratamento da mordida cruzada posterior de origem funcional, por contato prematuro em dentes decíduos, dentoalveolar e esquelético consiste, respectivamente, em desgaste seletivo, expansão dentoalveolar e disjunção maxilar(AU)


Malocclusions are classified as the third biggest oral health problem in the world, second only to caries and periodontal disease. The posterior crossbite is defined as the abnormal vestibular and lingual relationship of one or more teeth of the maxilla, with one or more teeth of the mandible, when the dental arches are in centric relation, being unilateral or bilateral. Objective: To perform a literature review on posterior crossbite. A selection of scientific articles was made from the Lilacs and Scielo databases using the descriptors "Cross Bite" and "Cross Bite Diagnosis", using as inclusion criterion works with year of publication between 2000 and 2018. Of the 694 articles found and delimited by the inclusive criteria, 49 articles were selected as a sample, which presented the theme listed for the research and which were discussed in the following sessions: a) Epidemiology; b) Etiology; c) Diagnosis; d) Treatment. The causes of posterior crossbite are multifactorial and its diagnosis must be meticulous, since it is of fundamental importance to recognize them and know how to apply interceptive measures to treat, since the results are satisfactory when planning an appropriate treatment early. The treatment of posterior crossbite of origin by premature contact in deciduous, dental and alveolar and skeletal teeth consists, respectively, of selective wear, dental and alveolar expansion and maxillary disjunction(AU)

RESUMEN

Digital smile design (DSD) used in combination with an esthetic pre-evaluative temporary restoration is a reliable means of minimizing the removal of tooth structure when ceramic veneers are being placed. When patients present with poorly aligned teeth, the use of clear aligners may be considered to properly position the teeth based on the desired outcome. This article, which illustrates a method to systematically diagnose, plan, and stage treatment for a smile makeover, describes the merging of DSD with clear aligner therapy to enable clinicians to recognize digitally where to position the teeth using orthodontic movement. This approach allows the desired esthetic design to be attained while enabling minimal tooth reduction.

RESUMEN

OBJECTIVES: Bolton ratio is used as a method for diagnosis of tooth size discrepancy. Tooth size discrepancy has an important role in the stability of results of final orthodontic treatment. The aim of this study was to determine and compare Bolton ratio in normal occlusion and different malocclusion groups of Iranian population. MATERIALS AND METHODS: This descriptive-analytic study comprises 240 orthodontic patient casts (for every malocclusion group: class I, class II division 1, class II division 2, class III, 30 males and 30 females) which have fully erupted and complete permanent dentitions from first molar to first molar, and also 60 persons (30 male-30 female) with normal occlusion. The mesiodistal tooth sizes were measured using digital caliper two times with a 4-week interval. RESULTS: The average mesiodistal size of all teeth in the malocclusion group was significantly bigger than in the normal occlusion group. Although there was no relationship between anterior ratio and gender or malocclusion groups, but a significant relationship between total ratio in Class II division 1 and normal occlusion was seen. Furthermore, a significant difference between anterior and total ratios in the present study and original Bolton's values was found. CONCLUSIONS: In the normal occlusion group, the anterior and total ratios were bigger than those in Bolton's original study. Also, "class II division 1" showed the lowest values of Bolton ratio among the other normal occlusion and malocclusion groups. Therefore, the original Bolton's values should be used conservatively in Iranian population.

RESUMEN

OBJECTIVE: Comparison of dental measurements between conventional plaster models, digital models obtained by impression scanning and plaster model scanning. PURPOSE: To evaluate and to compare the accuracy and reliability of tooth size, arch width and Bolton tooth size discrepancy measurements on 3 Dimensional (3D) digital models obtained by plaster dental model scanning, dental impression scanning and conventional plaster models. MATERIAL AND METHODS: This study was carried out on the maxillary and mandibular dental models of 25 patients with Angle Class I molar relationship and minimal crowding. Mesio-distal dimensions of the teeth, intercanine and intermolar arch width, and Bolton tooth size discrepancy measurements were calculated by conventional methods on plaster models, digital methods and on 3D models obtained from plaster model scanning and impression scanning. All measurements were repeated after three weeks for each of the investigated methods. Reliability of measurements was evaluated by Dahlberg formula and Pearson Correlation Coefficient. Comparisons of dental measurements between three methods were achieved with ANOVA Test. RESULTS: The repeated measurements were highly correlated for all methods. Method error was found within clinically acceptable limits. There was no significant difference between dental measurements on plaster dental models, digital models obtained from plaster dental model scanning and dental impression scanning. Results showed the methods being highly reliable and accurate for tooth size, arch width and Bolton analysis at total and anterior proportion calculation. CONCLUSION: Digital measurements of tooth size, arch width and Bolton tooth size discrepancy on digital models obtained from plaster dental model scanning and dental impression scanning showed high accuracy and reliability. There was no significant difference between the three methods for dental measurements.

RESUMEN

Objective: To evaluate and compare sensitivity and specificity of ANB, Wits, APDI and AF-BF to diagnose sagittal skeletal malocclusions, in children between 6 to 12 years old, using ROC curves, a widely accepted method for the analysis and evaluation of diagnostic tests. Material and Methods: A descriptive-comparative study of diagnostic tests was conducted. From a population of 3,000 children, a non-probabilistic sample of 209 was selected. The clinical classification of the patients as class I, II or III, made by a group of experts based on the visual inspection of models and photographs, was chosen as the gold standard. After calibration (ICC>0.94) the variables were measured in cephalograms. Eight ROC curves were plotted (I vs II, and I vs III for each one of the variables). The area under the curve was measured and compared (Ji-square test). Cut points were established. Results: To discriminate Class I from II, ANB showed the largest area under the curve (AUC) (0.876) and the cut point (best sensitivity and specificity) was at 5.75°. To discriminate class I from III, Wits showed the largest AUC (0.874) with a cut point of -3.25 mm. There were no statistical differences between the AUC for the four variables (p=0.48 y p=0.38 for class I-II and I-III). Conclusion: ANB and Wits performed better for the diagnosis of class II and III, respectively. Cut points in children were different from those reported in adults.

RESUMEN

DENTAL MALOCCLUSION IN CHILDREN: WARNING SIGNS. Dental malocclusions are common, and can be dental, skeletal and/or functional. Detecting these pathologies earlier is a signal to remove these causing factors, and act in favor of an harmonious growth of the jaws and the face. The dental alert signs include abnormalities of shapes, numbers, positions and eruption delay. Arch length discrepancy is due to a problem of teeth positions on the arch, resulting in overlaps or in interdental spaces. Dento-skeletal abnormalities are also to be analysed in the three space dimensions: the sagittal direction looks for a jaw too much projected forward or backward, the vertical and transverse directions evaluate mainly the recovery of the upper on the lower teeth and the absence of a narrow maxilla. The functional examination aims to check the stop of sucking habit after 3 years old, the ability of a good nasal breathing and a good swallowing. These disorders, in addition to the aesthetic consequences, lead primarily to temporomandibular joint disorders, masticatory and digestive disorders, ventilatory and obstructive sleep apnea, and dental and periodontal problems. These disorders are mainly fixed by the growth potential of the child, functional rehabilitation or using orthopedics or orthodontics appliances.

RESUMEN

Aims: Fetal alcohol spectrum disorder (FASD) is a developmental disorder caused by maternal alcohol intake (prevalence: 0.77%). Malocclusion has been described in case reports of patients with FASD, but reliable evidence for associations between FASD and malocclusion is not documented. Malocclusion is defined as tooth irregularity (prevalence: 14.6%) or incorrect relationship between the jaws such as lateral crossbites (prevalence: 3.1%). The purpose of this study was to investigate possible associations between malocclusion and FASD. Short summary: FASD prevalence is high and diagnosis is very difficult; Malocclusions can give additional hints for FASD diagnosis; Patients with FASD show growth deficits concerning the maxilla; Early and consistent orthodontic supervision and therapy can prevent facial asymmetries in FASD patients. Methods: Thirty patients with FASD and 30 patients of a healthy control group were examined. Inclusion criteria were mixed dentition, verified FASD/absence of FASD (control group), exclusion criteria were orthodontic treatment and disorders other than FASD. The extent and type of malocclusion were quantified with the peer assessment rating (PAR) index based on an analysis of orthodontic plaster models. In addition, anthropometric data such as gestational age, body weight and height at birth as well as present body weight, height and head circumference at examination date were assessed. Results: The PAR index showed a significant increase in malocclusions in FASD patients compared to the group that were not diagnosed with FASD (P = 0.002). FASD patients showed particular differences in the upper transversal dimension with a higher prevalence of crossbites (P = 0.018) and a lower head circumference (P < 0.001). Body weight (P < 0.001) and height (P < 0.001) were significantly lower for FASD patients at time of birth, but not at the present examination date (weight: P = 0.329; height: P = 0.496). When relating weight and height measures to age using percentile curves of physiological growth, clinically relevant discrepancies could be found for FASD patients. Conclusions: Our results show that malocclusion can provide additional evidence for FASD diagnosis. When FASD is diagnosed in a child, early referral to an orthodontist is advisable to stimulate maxillary growth and consequently prevent further malocclusions.

RESUMEN

INTRODUCTION: Discontinuation of orthodontic treatment has iatrogenic, psychological, ergonomic and financial consequences. The objective of this study was to investigate early risk factors (prior to installation) of discontinuation of orthodontic treatment. MATERIALS AND METHODS: We performed a case-control study between a group of patients who dropped their orthodontic treatment ("A") and a randomly selected group of patients who had completed their orthodontic treatment ("NA"). The two groups were compared, with descriptive, uni and multivariate analyzes. The risk factors assessed were age, gender, socioeconomic status, type of treatment, dysmorphism, malocclusion, need for treatment, compliance. RESULTS: In the dropout group 55 patients were included ("A") and 100 in the non-abandoned ("NA") group randomly selected. The subject at risk of abandonment was a girl of less than 11 years of age with a low socio-economic level with antero-posterior and vertical skeletal dysmorphisms, a molar class II, a teeth crowding, a small aesthetic prejudice or, on the contrary, very important, complex treatment (with extractions or with surgery) and having delays or missed appointments before the installation of the orthodontic appliance. CONCLUSION: Patients' motivation needs to be strengthened for both extremes: treatments that appear simple and conversely for complex cases requiring strong cooperation.

RESUMEN

INTRODUCTION: Most malocclusions are dysfunctional in origin and multidisciplinary care appears essential to correct as well as to maintain the orthopedic treatments performed. However, some "re-"educational therapies do not always deliver the desired results and the persistence of dysfunctions can thus compromise the stability of long-term results of orthodontic treatments. MATERIAL AND METHOD: Through a review of the literature, this article analyzes the former and current theories regarding maxillofacial rehabilitation. RESULTS: The two theories explaining failures in maxillofacial rehabilitation still need to be considered today because, so far, there are few data on the subject. DISCUSSION: The current evolution in the neurosciences makes it possible to achieve a better understanding and an improved technique regarding this type of reeducation, thus promoting greater adaptability on the part of the therapist.
