Disordered Breathing

ABSTRACTObjectiveThis study aimed to determine the prevalence of sleep-disordered breathing (SDB) and its association with malocclusion among children in Recife, Brazil.Methods390 children aged seven to eight years took part in the study, comprised by the body mass measurement, orthodontic examination and parent’s information required by the Sleep Disturbance Scale for Children. Statistics tools were Pearson’s chi-square and Lemeshow test.ResultsSDB was found in 33.3% of the children and associated with overjet (p= 0.007), anterior open bite (p=0.008) and posterior crossbite (p= 0.001). There was no association between BMI and SDB. The multivariate logistic regression model indicated that the anterior open bite (p= 0.002) and posterior crossbite (p = 0.014) have an association with SDB.ConclusionsResults of this study indicated that the prevalence of SDB was high and highly associated with malocclusion; anterior open bite and posterior crossbite are risk factors for SDB.

OBJECTIVE: To compare the cephalometric and intraoral characteristics between Long Face pattern and Pattern I patients, besides evaluating associations between subjective facial patterns, cephalometric facial patterns and the intraoral characteristics. METHODS: Through evaluation of frontal and right side extraoral photographs, three previously calibrated and experienced examiners selected 30 Long Face patients (Group 1) and 30 Pattern I patients (Group 2), aged between 9 and 19 years, of both genders. The cephalometric characteristics were assessed by the following variables: SN.GoGn, NS.Gn, AIFH, SNA, SNB, ANB, 1.1, 1.NA,1-NA, 1.NB, 1-NB, NA.Po, nasolabial angle and H-Nose. Clinical evaluations were also performed to determine the presence of posterior crossbite, anterior open bite and type of Angle's malocclusion. The cephalometric data were compared by independent t test. The chi-square test was used to evaluate the association between qualitative variables. RESULTS: Significant differences were observed between groups regarding the variables SN.GoGn, NS.Gn, AIFH, ANB, NA.Pog, 1-NA, 1.NB and 1-NB, with an increase of these measures in Group 1. There were also significant differences between groups on variable 1.1, being lower in Group 1 than in Group 2. CONCLUSIONS: The Long Face was associated to Angle Class II malocclusion, to the presence of posterior crossbite and to anterior open bite. The Long Face subjective facial pattern was associated to dolichofacial cephalometric pattern.

Objective: this study aimed to evaluate malocclusion occurrence in children with complete primary dentition, describing the most frequent one and verifying potential associations with demographic, socioeconomic, and behavioral variables. Subjects and method: 502 children with complete primary dentition from primary schools in the city of Pelotas, RS, Brazil, were examined. Data was collected based on questionnaires distributed to the mothers, as well as on physical examinations of the oral cavity. The children with malocclusion presented at least one of the following changes: anterior open bite, deep overbite, posterior crossbite, and overjet. Chi-square tests for heterogeneity and linear trend were used to verify associations with demographic, socioeconomic, and behavioral variables. Results: the occurrence of malocclusions in the population studied was 67.5%. From them, 33.6% presented anterior open bite, 22.3% presented deep overbite, 9.8% presented posterior crossbite, and overjet was present in 1.8%. The most frequent malocclusion was anterior open bite, which was directly associated with the use of pacifier (p

Adequate planning and early treatment of Angle Class II malocclusion with maxillary atresia and anterior open bite provides harmonization of maxillomandibular bone bases in the three planes of space. Orthodontic aligners have emerged as an alternative treatment having the following advantages: being more aesthetic and more comfortable for the patient, less treatment time when they are correctly indicated, less chairside time, less complications, possibility of remote monitoring, easier feeding, and dental hygiene. On the other hand, they offer difficulties to treat adults with severe skeletal Class II malocclusions, posterior crossbite and anterior open bite. Therefore, the objective of this clinical case report is to early correct skeletal Class II malocclusion with maxillary atresia through the use of mechanical orthopedics and devices that help eliminate habits and close the anterior open bite, and later the use of orthodontic aligners to finish the treatment. It was concluded that the early interceptive treatment of malocclusion was efficient to harmonize the bone bases in the anteroposterior, vertical, and transversal directions, changing this malocclusion from high to low complexity and, consequently, highly predictable and with an excellent prognosis for treatment with orthodontic aligners. The treatment with ClearCorrect aligners corrected the occlusion in a shorter period of time when compared to corrective orthodontics and with a high predictability in relation to the virtual setup.

This epidemiological survey was conducted on 2,016 children from 8 private and 12 public preschools at the city of Bauru, São Paulo, Brazil. The sample was composed of 1,032 males and 984 females in the primary dentition stage, aged 3 to 6 years. Normal occlusion was observed in 26.74% of the sample; thus, 73.26% of children presented some type of malocclusion. Among the malocclusions, the following transverse problems were diagnosed: unilateral posterior crossbite (11.65%), anterior open bite associated with posterior crossbite (6.99%), bilateral posterior crossbite (1.19%), unilateral posterior crossbite associate with anterior crossbite (0.79%) and full crossbite (0.19%) totalizing 20.81% of the transverse problems. Mandibular functional deviation was observed in 91.91% of children with unilateral posterior crossbite, characterizing the functional unilateral posterior crossbite. The results demonstrated that the prevalence of posterior crossbite was compatible with previous data in the literature, with predominance of functional unilateral posterior crossbite.

The Impact

Objectives: To determine the association between types of malocclusion and quality of life in children between 8-10 years of age and establish correlations between the severity of the malocclusion and particular bio-psychosocial variables. Study design: The sample was made up of 102 schoolchildren aged 8-10 years. Clinical exams were performed using the criteria of the Dental Aesthetic Index (DAI) to determine the presence and severity of malocclusions. The impact on quality of life was assessed using the Child Perceptions Questionnaire (CPQ8-10). Statistical analysis involved the chi-square test, Fisher's exact test and Spearman's correlation analysis. Results: Malocclusions affected 61% of the children examined. There was a positive correlation between total CPQ8-10 and DAI scores (P = 0.034). The following types of malocclusion had a significant effect on the quality of life of the children: upper anterior irregularity ≥ 2 mm, anterior open bite ≥ 2mm and diastema ≥ 2mm. Children with malocclusion experienced a greater negative impact on quality of life in comparison to those without malocclusion. Conclusions: Malocclusions had a negative influence over the quality of life of children between 8-10 years of age. More severe malocclusions had a greater impact with regard to social, emotional and functional aspects.

Purpose: To evaluate the prevalence of malocclusions in preschool children in the city of Campina Grande, PB, Brazil, and verify the existence of associations between malocclusions and deleterious oral habits, gender and age. Methods: 342 children (3-5-year-old; 196 boys and 146 girls) with complete primary dentition and no previous orthodontic treatment were randomly selected from children regularly attending municipal day care centers. The occurrence of the following malocclusions was evaluated: accentuated overjet and overbite, anterior open bite and posterior crossbite. A calibrated experienced examiner (Kappa = 0.86) performed all clinical examinations under natural lightening after drying the teeth and soft tissue with gauze. Yates' chi-square and Fisher's exact tests verified the association between the variables and odds ratio. Significance level was set at 5%. Results: Malocclusions and deleterious oral habits were observed in 74% and 73.4% of the children, respectively. The prevalence of malocclusion was 68.9% in boys and 80.9% in girls. Accentuated overjet (45%) and anterior open bite (42.4%) were the most prevalent malocclusions. There was statistically significant difference (P = .008) between genders. However, no statistically significant differences (P = .47) were found among the age groups. Accentuated overjet, anterior open bite and posterior crossbite showed a positive association with the presence of deleterious oral habits. Conclusions: The high prevalence of malocclusions and deleterious oral habits observed in this pediatric population is supportive to the fact that oral health professionals that treat patients in these age groups should be aware of the importance of an early and accurate diagnosis in order to avoid the aggravation of occlusal alterations in the future.

Rationale. Myotonic dystrophy (MD) is a multisystemic autosomal dominant disease characterized by myotonia and progressive muscular weakness and atrophy. Objective. The purpose of this study was to describe the dental, skeletal and muscular features in a family with myotonic dystrophy type II and to discuss possible therapeutic strategies. Methods and results. This study presents the case of a family (a mother and two daughthers) diagnosed with myotonic dystrophy type II. Beside the medical history and genetic tests, each subject underwent a clinical examination including impression taking, intra- and extraoral photographs and cephalometric analysis. Our investigations revealed alterations in the transversal and vertical planes. Conclusions. Our findings were consistent with previously reported craniofacial features of patients affected by myotonic disorders, and they may be important diagnostic signs of a congenital muscular disease. We found that the most predominant malocclusions were the anterior open bite and posterior crossbite, but the tendency to class III malocclusion is in contradiction with their findings.

The objective of this work was to determine the prevalence of individual traits of malocclusion in a sample of three Brazilian regions orthodontic patients and to detect interregional population differences in the prevalence of certain occlusal characteristics.  The present study was based on the examination of dental casts, intraoral photographs and panoramic radiographs of 947 orthodontic patients from 3 cities: 363 from Fortaleza (CE), 270 from Maringá (PR) and 314 from Bauru (SP), respectively, representing the Northeast, South and Southeast Brazilian regions. The relationship of the first maxillary and mandibular molars according to Angle’s classification, overjet, overbite, crowding, posterior crossbite and maxillary median diastema were examined. The chi-square and ANOVA tests were used to determine potential differences in the distribution of malocclusion when stratified Brazilian regions. Class I malocclusion was found in 499 (52.69%), Class II in 395 (41.71%) and Class III malocclusion in 53 (5,59%) subjects of all examined. Deep overbite (3.59%), midline diastemas (5.17%) and posterior crossbite (4.75%) were observed more frequently in Bauru; however, in Maringá, normal overbite (13.3%) and open bite (4.75%) were more prevalent. The results of this study showed that Class I malocclusion was the most prevalent, followed by Class II and Class III malocclusions. These occlusal relationships evaluated in the three Brazilian regions follow the same pattern of frequency as the result presented by the general population of the sample.
