“…Oral habits can be divided in two different modes: nutritive (breast and bottlefeeding) or nonnutritive sucking habits (bruxism, nail biting, thumb/finger sucking, etc.). In the case of nutritive oral habits, it was shown that bottle-fed babies had a significant reduced masseter activity [37], which can probably reduce the damage of a possible bruxism crisis. In the other hand, it has been suggested that longer breastfeeding may be associated with fewer occlusal abnormalities [38].…”

“…20 Second, the brachycephalic mandibular arch format is more easily reached when the child is breastfed, which in turn allows appropriate tooth eruption position. 21 Finally, exclusive breastfeeding is strongly and inversely associated with the frequency, intensity, and duration of pacifier use, which in turn may lead to severe malocclusion. 8,10 A systematic review regarding the risks and benefits of pacifier use highlighted the negative impact of pacifier use on breastfeeding.…”

OBJECTIVES: The distinct effect of exclusive and predominant breastfeeding on primary dentition malocclusions is still unclear. We hypothesized that exclusive breastfeeding presents a higher protective effect against malocclusions than predominant breastfeeding and that the use of a pacifier modifies the association between breastfeeding and primary dentition malocclusions.METHODS: An oral health study nested in a birth cohort study was conducted at age 5 years (N = 1303). The type of breastfeeding was recorded at birth and at 3, 12, and 24 months of age. Open bite (OB), crossbite, overjet (OJ), and moderate/severe malocclusion (MSM) were assessed. Poisson regression analyses were conducted by controlling for sociodemographic and anthropometric characteristics, sucking habits along the life course, dental caries, and dental treatment.RESULTS: Predominant breastfeeding was associated with a lower prevalence of OB, OJ, and MSM, but pacifier use modified these associations. The same findings were noted between exclusive breastfeeding and OJ and between exclusive breastfeeding and crossbite. A lower prevalence of OB was found among children exposed to exclusive breastfeeding from 3 to 5.9 months (33%) and up to 6 months (44%) of age. Those who were exclusively breastfed from 3 to 5.9 months and up to 6 months of age exhibited 41% and 72% lower prevalence of MSM, respectively, than those who were never breastfed.CONCLUSIONS: A common risk approach, promoting exclusive breastfeeding up to 6 months of age to prevent childhood diseases and disorders, should be an effective population strategy to prevent malocclusion. WHAT'S KNOWN ON THIS SUBJECT:Breastfeeding provides a protective effect against some malocclusions, and there is a strong inverse correlation between the duration of breastfeeding and the duration of pacifier use. WHAT THIS STUDY ADDS:The protective effects of predominant and exclusive breastfeeding against malocclusion are distinct: exclusive breastfeeding reduces the risk of malocclusions regardless of pacifier use, whereas the effect of predominant breastfeeding depends on the duration of the pacifier use.

“…Chewing and swallowing problems of children at kindergarten age have been reported frequently (Yokomizo, 1992). These difficulties have long been suspected to be related to the too soft and too nutritious foods prevalent in the present diet, and the manner of nursing has also been put in question (Ito et al, 1982;Inoue et al, 1995;Sakashita et al, 1996, Liu et al, 1998.There are three main methods for evaluating the growth and development of the masticatory system: morphological measurement of the dentition ; functional analysis of muscle activity (Nakano, 1993;Sakashita et al, 1998); and estimation of masticatory ability (Yurkstas & Manly, 1950). In the first, the size of the jaw and arch length deficiency cannot be measured before tooth eruption; in the second, although the functional record, such as electromyography (EMG) of the masseter muscle, may be available, it is not easy to apply for screening purposes because it requires expensive equipment and specially trained personnel.…”

Objective: This paper describes the development of a reliable scale of standards for use in evaluating the progress of the transition from milk to solid food in infants and preschool children. The maturation of chewing and swallowing behavior in infants and young children, which enables processing of solid food, varies, and a scale would assist not only in the instruction of mothers and nurses but also in preventing delay in the introduction of solid food. Design: A range of 159 reference foods were selected on the basis of intake during the period of transition from liquid to solid food. These foods were listed in our previous study, Validity and reliability were tested to create a scale. Methodology: Foods were selected on the basis of 50% of the subjects studied being able to eat them, and on the food groups classified by cluster analyses using the Varclus procedure of SAS. Validity, of the scale was tested by using Pearson's correlation coefficient between the scale score of selected food items and the total score of all 159 food items. The total score of 159 food items was calculated using the general linear models (GLM) procedure of SAS. Reliability was tested using Cronbach's coefficient a. Setting: Public health centers in Aomori, Tokyo, Saitama, Nagano, and Okinawa (Japan). Subject: Five hundred and eighty healthy mothers and children from 2 to 46 months were randomly selected and 470 (81.0%) completed the study. To avoid regional bias, subjects were drawn from northern to southern prefectures in Japan, namely Aomori, Tokyo, Saitama, Nagano, and Okinawa. Results: Twenty food items were selected. By analyzing the score correlation using Pearson's correlation coefficient (R ¼ 0.97, Po0.001) and GLM (R 2 ¼ 0.95, Po0.001), it was confirmed that these 20 food items adequately represented the original 159. The reliability was also found to be sufficient (Cronbach's coefficient a ¼ 0.96).Conclusions: The findings demonstrate that a scale of standards for measuring progress in chewing ability can be created using 20 food items. Such a standard will provide a useful basis against which to assess delay of solid food introduction in childhood. IntroductionThe ways in which the maturation of chewing and swallowing behavior in an infant enables it to eat solid food are various. In Japan, a suggested program for the transitional process from liquid to solid food focused on 1 y after birth and was supported by the Japanese Ministry of Health and Welfare (Society for Maternal and Child Health, 1997). However, many babies do not follow the instructed transitional process (Sakashita, 1992), and many pre-school children are not good at chewing and swallowing due to Contributors: RS participated in the study design, collected the data, did the statistical analysis, participated in the discussion of results and wrote the paper.
