The influence of sucking habits on occlusion development in the first 36 months

Abstract

Objective: The objective of this study was to identify the influence of sucking habits on the occlusal characteristics of the deciduous dentition. Methods:The initial sample consisted of 86 infants, aged 0 to 3 months. Seven home visits were performed, when and information on breastfeeding practice, nutritive and non-nutritive sucking habits, mouth breathing and dentition development was collected. From the first sample, impressions of the dental arches were obtained from 58 children at the age of 36 months (+2.51SD). Dental casts were obtained and two examiners, trained and calibrated by the Kappa and Pearson Correlation tests, measured several parameters of dental occlusion, such as arch length, depth, and width. Results:The results showed that bottle feeding before 6 months was associated to an increased mandibular intermolar width (p=0.01). Pacifier use before 6 months was statistically associated to a reduction of the maxillary intercanine (p=0.03) and intermolar (p=0.03) width. In addition to these findings, the increased molar depth of the maxillary arch was associated to loss of lip closure before the age of 12 months (p= 0.03). Conclusion:According to these results, it could be concluded that sucking habits interfere with the determination of some deciduous occlusal characteristics: pacifier sucking limits lateral-lateral maxillary growth, bottle feeding favors lateral-lateral mandibular growth and open bite development, and the lack of lip closure favors the anteroposterior maxillary growth.

Sete visitas domiciliares foram realizadas, quando informações sobre a prática da amamentação, hábitos de sucção nutritivos e não-nutritivos, respiração bucal e desenvolvimento da dentição foram coletados. A partir do grupo inicial, 58 crianças foram moldadas em consultório na idade média de 36±2,51 meses. Modelos de estudo foram obtidos e medidos diversos parâmetros da oclusão dentária, tais como profundidade, extensão e largura das arcadas, por dois examinadores comprovadamente calibrados pelo teste de concordância Kappa e correlação de Pearson.Resultados: os resultados demonstraram que o aleitamento artificial por mamadeira antes dos 6 meses esteve associado à largura intermolares inferior (p=0,01). A sucção de chupeta antes dos 6 meses foi estatisticamente associada à diminuição da largura intercaninos superior (p=0,03) e intermolares superior (p=0,03). Somando-se a isso, o aumento da extensão molar da arcada superior associou-se à perda do vedamento labial antes dos 12 meses de vida (p=0,03).Conclusão: é possível concluir-se que os hábitos de sucção interferem na determinação de características oclusais na dentição decídua.

Breastfeeding Versus Bottle Feeding on Malocclusion in Children: A Meta-Analysis Study

“…Therefore, this meta-analysis included only observational studies, which have lower evidence levels than randomized clinical trials (Burns, Rohrich, & Chung, 2011; GRADE Working Group, 2004). Only a few cohort studies (de Morais, Mota, & Amorim, 2014; dos Santos Neto, Oliveira, Barbosa, Zandonade, & Oliveira, 2012; Karjalainen, Rönning, Lapinleimu, & Simell, 1999; Lescano de Ferrer & Varela de Villalba, 2006; Moimaz et al, 2014; Warren & Bishara, 2002) and study designs nested within cohorts (Caramez da Silva et al, 2012; Peres et al, 2007; Peres, Cascaes, Peres, et al, 2015; Viggiano et al, 2004), which are considered more robust than cross-sectional studies, were identified (Burns et al, 2011; GRADE Working Group, 2004). Furthermore, three such studies were not included in our quantitative synthesis due to a lack of raw data (dos Santos Neto et al, 2012; Karjalainen et al, 1999; Peres, Cascaes, Peres, et al, 2015).…”

Evaluation of occlusal groove morphology of primary mandibular second molar in an Indian population

“…[13] Genetic factors, long-term environmental factors, sucking habits, and other parafunctional habits influence the final form of the tooth. [34] Development of teeth is a long-term, progressive process which occurs as a result of molecular and cellular interactions. It has critical stages of development which can be influenced by genetic, epigenetic, and environmental factors.…”

“…Occlusal characteristics of the primary teeth can also be influenced by sucking habits and parafunctional habits like bruxism. [4] The variations in tooth form and groove pattern are frequently encountered which can be studied by measurements. [5] Variations in the occlusal surfaces of the mandibular molars are based on the study by Gregory and Hellman.…”

Interferência dos bicos ortodônticos e convencionais no sistema estomatognático: revisão sistemática

“…Harmful oral habits, such as thumb sucking or the use of pacifiers and bottles, are learned and often repeated patterns of muscle contraction (14) and may cause damage to the morphophysiology of the stomatognathic system (7)(8)(9) . Among these, the most common are malocclusion (15)(16)(17) , bruxism (18,19) , and difficulties in lip sealing, suggesting changes in the orofacial muscles (9,17) . In addition, harmful oral habits are risk factors for mouth breathing and changes in chewing and swallowing (17,20,21) .…”

“…Among these, the most common are malocclusion (15)(16)(17) , bruxism (18,19) , and difficulties in lip sealing, suggesting changes in the orofacial muscles (9,17) . In addition, harmful oral habits are risk factors for mouth breathing and changes in chewing and swallowing (17,20,21) . The severity of the changes found is directly related to the frequency, duration, and intensity of the habit (22) , as well as the individual predisposition, conditioned by genetic factors (23) .…”
