- ItemSomente MetadadadosAlterações dentárias e esqueléticas em crianças respiradoras bucais submetidas à expansão rápida maxilar(Universidade Federal de São Paulo (UNIFESP), 2021) Campos, Luciano Nogueira De Almeida [UNIFESP]; Cappellette Junior, Mario [UNIFESP]; Universidade Federal de São PauloIntroduction: Maxillary transverse deficiency is one of the most common skeletal alterations in the craniofacial region with an etiology comprising genetic and/or functional factors such as mouth breathing. The rapid maxillary expansion (RME) procedure is effective to produce transverse skeletal correction by orthopedic movement of the maxillary bones. Simultaneously with the orthopedic effect, an orthodontic effect occurs by tooth movement. When performed before the peak of pubertal growth, it induces more pronounced skeletal changes and directs the growth and transverse development of the maxilla. Objectives: To evaluate by computed tomography, the effects of RME, in the short term, on skeletal and dental dimensions in mouth breathing patients and to compare the results obtained according to the age. Methods: Measurements in a sample consisting of 42 mouth breather patients, ages ranging from 7 to 13 years and skeletal maxillary deficiency. The sample was assessed according to age: 21 children aged 7 to 9 years and 21 children aged 10 to 13 years. All were submitted to computed tomography exams in 2 phases: T1- pre-RME and T2 - six months post-RME . The Dolphin® Imaging image manipulation program (Dolphin Imaging & Management Solutions, Chatsworth, California Version 11.7 Premium) was used for evaluation of transverse dental dimensions in the canine region (13-23) and first molars (16 -26), and transverse skeletal dimensions in the nasal cavity (Rhi-ENA) and facial width (ZR-ZL). Results: Both groups showed significant increases in all variables. Regarding alterations between T1 and T2, there were no significant differences between the groups (p> 0.05). Only significant differences were registered in the Rhi-ENA measure (p = 0.011): the variation was significantly higher in patients in the younger group (+ 6.4%, d = 1.76) than in the older one (+ 2.5%, d = 0.55). Conclusions: The orthopedic effects of ERM, in short term, was effective in both groups with the increase in linear measures of dentofacial height and width.
- ItemSomente MetadadadosAvaliação do espaço aéreo anterior da cavidade nasal e qualidade de vida em crianças respiradores bucais submetidos à expansão rápida da maxila(Universidade Federal de São Paulo (UNIFESP), 2020-05-28) Nagai, Lucia Hatsue Yamamoto [UNIFESP]; Cappellette Junior, Mario [UNIFESP]; Universidade Federal de São PauloIntroduction: The anterior portion of the nasal cavity includes the critical region of maximal resistance to airflow that even small changes in its geometry can have a significant impact on nasal airflow. Objectives: to assess the effects of rapid maxillary expansion (RME) on the anterior skeletal and soft tissue structures of the nasal cavity in mouth-breathing children and correlated these findings with the patient’s quality of life. Methods: 35 mouth-breathing patients (mean age 10.7±2.0 years) submitted to RME were evaluated by means of computed tomography at preRME and 4-5 months thereafter. Subjective symptoms were assessed by using a validated quality of life questionnaire answered by patients and patients’ parents/legal guardians. Results: The total anterior nasal volume increased by 20.47% on average during the overall observation period. The skeletal and soft tissue volumes increased by 26.5% and 17.6% respectively, and a cross-sectional area increased by 19.96% on average. Different combinations of angles were found, however, more significant increases occurred when the angular value of one side was much smaller than opposite side. There was a statistically significant reduction in the mean scores of the quality of life scale, indicating a significant improvement in quality of life between T1 and T2. Conclusions: In the short term, RME promote a significant increase in the anterior nasal volume, with a higher proportion within the skeletal boundaries. This, associated with an increased minimum cross-sectional area, may have contributed to respiratory improvement. In addition, different combinations of nasal valve angles suggest that RME can influence the position of the septum.
- ItemSomente MetadadadosEfeitos da expansão rápida da maxila nas estruturas do terço médio e inferior da face em crianças respiradoras bucais(Universidade Federal de São Paulo (UNIFESP), 2021) Marra, Artur Rodrigues [UNIFESP]; Cappellette Junior, Mario [UNIFESP]; Universidade Federal de São PauloIntroduction: Transverse maxillary atresia should be corrected as early as possible in the growth phase, with resources that provide skeletal changes, and one of the procedures widely addressed in the literature is rapid maxillary expansion (RME). Objective: Evaluate, in short term, the dentoskeletal effects of RME on maxillary and nasal dimensions using computed tomography images ( pre and post-RME at 6 months). Methods: Frontal norm computed tomography (CT) images of 30 patients ranging from 7 to 10 years old, mean age of 8.7 years, 18 males and 12 females, mouth breathers, who underwent RME. Linear measurements Pre (T1) and Post (T2) RME were performed, and all measurements were repeated by the same observer (intraobserver error) and by a second observer (interobserver error). Results: Comparing the results of the seven measures evaluated before RME (T1) and after RME (T2), there were significant differences, between T1 and T2, in the measures facial width, nasal height, nasal width, maxillary width, maxillary height and in the upper intermolar distance. Regarding the lower intermolar distance, there were no significant differences between T1 and T2. Facial width registered the strongest variation in the values of linear measurements between T1 and T2. Conclusion: After comparative analysis of the results obtained pre and post RME, we can conclude that the effects of rapid maxillary expansion, in short term, show a significant increase in facial width, nasal height, nasal width, maxillary width, maxillary height and upper intermolar distance.
- ItemSomente MetadadadosQualidade de vida em pacientes submetidos à expansão rápida da maxila(Universidade Federal de São Paulo (UNIFESP), 2020-08-27) Hoppe, Daniela Pimentel Machado Renofio [UNIFESP]; Cappellette Junior, Mario [UNIFESP]; Universidade Federal de São PauloIntroduction: This study evaluated the short-term volume changes in the nasomaxillary complex of mouth breathers after rapid maxillary expansion and correlated the outcomes with the patient’s quality of life. Objectives: Estimate whether rapid maxillary expansion can support on the improvement of the quality of life after treatment. Methods: A total of 35 mouth-breathing patients with maxillary constriction (mean age of 10.3 years) were evaluated by means of multslice computed tomography. Subjective symptoms were assessed with the use of a standardized quality of life questionnaire answered by patients and patients’ parents/legal guardians before rapid maxillary expansion and at 6 months later. Results: The total volume increased by 24,7% on average during the overall observation period. The nasomaxillary complex increased dimensionally, and the pretreatment subjective respiratory condition had improved significantly 6 months post rapid maxillary expansion. Conclusions: Rapid maxillary expansion results in a significant dimensional increase in the nasomaxillary complex. Furthermore, it also has a positive impact on the quality of life of mouth-breathing patients with maxillary constriction.
- ItemAcesso aberto (Open Access)Relação da respiração oral e hábitos de sucção não-nutritiva com alterações do sistema estomatognático(CEFAC Saúde e Educação, 2012-04-01) Pacheco, Andrielle De Bitencourt; Silva, Ana Maria Toniolo Da [UNIFESP]; Mezzomo, Carolina Lisbôa; Berwig, Luana Cristina; Neu, Aline Prade; Universidade Federal de Santa Maria; Universidade Federal de São Paulo (UNIFESP); Pontifícia Universidade Católica do Rio Grande do SulPURPOSE: to investigate the relationship between oral breathing of different etiologies and persisting non-nutritive sucking habits in establishing structural alterations in the stomatognathic system. METHOD: the sample comprised 78 children between 7 and 11 year old, 36 boys and 42 girls, divided in two groups based on non-nutritive sucking habits and breathing mode. All children underwent otolaryngological, speech-language and dentistry evaluations. Data analysis was performed using Chi-square test considering significance level of 5%. RESULTS: there was significant association between breathing mode and lips posture; between breathing mode and hard palate; between nonnutritive sucking habits and cheek posture. In the analysis of the association between breathing mode and nonnutritive sucking habits with the habitual lips posture and hard palate, we also forund a statistical significance. CONCLUSION: it was found that the altered lips posture and hard palate was more frequent in the vicious and obstructive mouth breathers groups. The asymmetrical cheeks posture was more frequent among children with habits. The altered lips posture and hard palate alterations were also more frequent in oral breathers regardless of the presence or absence of any habits.
