Hábitos Bucais como Fatores de Risco para a Mordida Aberta Anterior / Oral Habits as Risk Factors for the Anterior  Open Bite

A mordida aberta anterior é considerada como a presença de um trespasse vertical negativo existente entre as bordas incisais dos dentes anteriores, tanto superiores, quanto inferiores, seu acontecimento é principalmente na infância e durante a troca de dentição. Conhecer precocemente os hábitos bucais deletérios é de grande importância, pois, as intervenções prévias auxiliarão para uma melhor qualidade de vida. Este trabalho tem como objetivo apresentar os principais hábitos bucais causadores da mordida aberta anterior, assim como suas classificações, diagnóstico e tratamentos para o problema. Os principais hábitos bucais que facilitam para a ocorrência da mordida aberta anterior são relacionados principalmente com a sucção digital, uso de chupetas e mamadeiras. Os principais problemas podem incluir fator estético, e também psicológico, uma vez que a mordida aberta causa um sorriso desarmônico. Através do desenvolvimento deste trabalho foi possível perceber a importância do diagnóstico precoce da mordida aberta anterior e suas principais características.

Condylar resorption (CR) can be categorized into functional and dysfunctional remodelling of the temporomandibular joint (TMJ). The literature describes dysfunctional remodelling of the TMJ as idiopathic condylar resorption (ICR). Idiopathic condylar resorption (ICR) is a well-documented but poorly understood pathological entity that can occur spontaneously or post-orthognathic surgery. It predominantly affects young women, with other risk factors including Class 2 malocclusion with steep mandibular plane angles. It is distinguished by a decreased condylar head volume and ramus height, progressive mandibular retrusion and an anterior open bite. Its aetiology can be categorized into surgical and non-surgical risk factors. These include hormones, systemic disease, trauma, mechanical load and surgical risk factors, such as magnitude and direction of mandibular movement, type of surgical fixation and length of post-operative maxilla-mandibular fixation. ICR is a diagnosis of exclusion, and identified by a combination of clinical, radiographic and haematological findings. Multiple treatment options have been described in the literature, including medical management, orthodontics, orthognathic surgery, TMJ surgery, TMJ and orthognathic surgery combined, and total joint prosthesis reconstruction. Further research is required to better understand the aetiology of ICR and more long-term, controlled, multicentre clinical studies are needed to evaluate the outcomes of surgical and non-surgical management of CR patients. CPD/Clinical Relevance: Idiopathic condylar resorption has many presentations and potential causes that can greatly impact the decisions and outcomes for orthodontic/orthognathic treatment.

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.

Thumb Sucking

Deleterious oral habits, such as non-nutritive sucking or tongue thrusting, if not intercepted at an early stage can cause complex malocclusions. This manuscript describes a clinical case report of a successful interception of a severe anterior dental open bite caused by thumb sucking and tongue thrusting habits. The case involved a six-year-old female patient treated with the use of palatal spurs and maxillary removable crib followed by monitoring the development of dental occlusion. At the end of the interceptive phase acceptable results were achieved, showing the efficacy of the treatment undertaken as well the importance of an early intervention to remove harmful oral habits.

Nutritive Sucking

OBJECTIVE: To estimate the prevalence of malocclusion and to examine the effects of breastfeeding and non-nutritive sucking habits on dentition in six-year-old children. METHODS: A cross-sectional study was carried out nested into a birth cohort conducted in Pelotas, Southern Brazil, in 1999. A sample of 359 children was dentally examined and their mothers interviewed. Anterior open bite and posterior cross bite were recorded using the Foster & Hamilton criteria. Information regarding breastfeeding and non-nutritive sucking habits was collected at birth, in the first, third, sixth and 12th months of life, and at six years of age. Control variables included maternal schooling and child's birthweight, cephalic perimeter, and sex. Data were analyzed by Poisson regression. RESULTS: Prevalence of anterior open bite was 46.2%, and that of posterior cross bite was 18.2%. Non-nutritive sucking habits between 12 months and four years of age and digital sucking at age six years were the main risk factors for anterior open bite. Breastfeeding for less than nine months and regular use of pacifier between age 12 months and four years were risk factors for posterior cross bite. Interaction between duration of breastfeeding and the use of pacifier was identified for posterior cross bite. CONCLUSIONS: Given that breastfeeding is a protective factor for other diseases of infancy, our findings indicate that the common risks approach is the most appropriate for the prevention of posterior cross bite in primary or initial mixed dentition.

Logistic Regressions

ABSTRACT Objective: To investigate risk factors specific to posterior crossbite and anterior open bite at the age of 3 years. Materials and Methods: The study included 422 children of the French EDEN mother-child cohort. The main outcomes were the presence of posterior crossbite and anterior open bite assessed by dentists at 3 years. Social characteristics (collected during pregnancy), neonatal characteristics (collected at birth), duration of breast-feeding (collected prospectively), sucking habits at 3 years, and open lips (as a proxy for mouth breathing) were studied and two logistic regressions conducted. Results: Preterm birth appears to be a risk factor specific for posterior crossbite (OR: 3.13; 95% CI: 1.13–8.68), whereas small for gestational age seems to be associated with a lower risk of posterior crossbite (OR: 0.32; 95% CI: 0.12–0.87). Ongoing pacifier or thumb sucking at 3 years is a risk factor for both posterior crossbite and anterior open bite. Conclusions: Children born preterm seem to be more at risk for posterior crossbite than those born at term. Different mechanisms may be involved in posterior crossbite and anterior open bite.
