“…Similar findings were reported by Togawa et al (14), who found that symptoms of gastroesophageal reflux disease were more often observed in patients with skeletal Class III malocclusion than in normal subjects, as determined by questionnaires. We found that subjects with malocclusion have a higher incidence of digestive complaints and gastrointestinal disorders, but there was no significant difference between the two groups.…”

Masticatory function is significantly lower in individuals with malocclusion than in those with normal occlusion. Although several studies suggest that masticatory function influences gastrointestinal digestive function, the relationship between malocclusion and gastrointestinal symptoms has not been studied extensively. We hypothesised that insufficient masticatory function would increase the functional burden of the stomach and have some influence on the gastrointestinal system. The purpose of this study was to investigate masticatory function and gastric emptying rate in subjects with malocclusion. Eleven healthy dentate female volunteers and eleven female patients with maloc-clusion underwent a (13) C-acetate breath test with a liquid meal. Maximum (13) CO2 exhalation time (Tmax ) was compared statistically between both groups. Masticatory function was assessed by colour-changeable chewing gum. In addition, the frequency scale for the symptoms of gastroeso-phageal reflux disease (FSSG) and questionnaires on food intake were given to both groups. The mean Tmax of the malocclusion group was significantly longer than that of the normal occlusion group (P = 0·007). Masticatory performance, measured by colour-changeable gum and questionnaires, was significantly lower in the malocclusion group than in the normal occlusion group (P = 0·023, P = 0·003). There was no significant difference in the FSSG results between the two groups (P = 0·262). This study suggested that there was a correlation between malocclusion and gastric emptying function in women.

The relationship between malocclusion and the gastrointestinal system has only been examined occasionally, while several pertinent studies have addressed the chewing function as a functional link between oral structures and the gastrointestinal tract. Following an overview of the physiological masticatory process, the available evidence regarding associations among dental status, chewing function and gastrointestinal disorders are summarized. Finally, a review of the relationships between orthodontic deformities and mastication is presented.

“…The effect of mastication on gastric function has long been a topic of interest but the association between the two processes remains unclear. [1][2][3][4][5][6][7][8] Good mastication, determined by the size of chewed food particles, was thought to help digestion in the stomach and shorten the gastric emptying. Occlusal contact area is among one of the most important determinants of good masticatory performance.…”

Background Good mastication is thought to help digestion in the stomach, hence promoting the health of the gastrointestinal system. However, the correlation between masticatory and gastric function has been controversial. This is partly explained by different food types used to assess the performance of the two organs. Recently, frankfurter sausage has been proposed to be suitable for both masticatory performance and gastric emptying tests. Objectives To examine the relationship between masticatory performance, occlusal contact area, chewing time and cycles, and gastric emptying scintigraphy parameters in healthy dentate adults. Materials and Methods Forty healthy subjects (15 men: 25 women, age 23.9 ± 3.8 years) underwent masticatory performance tests and gastric emptying scintigraphy using frankfurter sausage as a test food. Masticatory performance was calculated as the median particle size (MPS) of chewed frankfurter sausage cubes after 30 chewing cycles. Gastric emptying scintigraphy was performed using frankfurter sausage mixed with technetium‐99 m‐labelled microwaved egg meal. Cumulative occlusal areas of contact‐near contact (cACNC) were determined by silicone bite registration and image‐analysed. Chewing time and cycles before swallowing were also recorded. Results No significant differences in MPS, cACNC, chewing time and cycles, or gastric emptying parameters were observed between gender. Bivariate correlation showed masticatory performance, occlusal contact area, chewing time and cycles were not correlated with gastric emptying parameters (P > 0.05). Conclusion Using the same test food to assess the masticatory and gastric function in dentate subjects, the present study showed that masticatory performance, occlusal contacts, chewing time and cycles did not affect gastric emptying.
