Hypothesis
The study aims to compare modifications of chewing function before and after bariatric surgery in three groups of obese patients differing in dental status.
Conclusion
After bariatric surgery, all obese patients modified their chewing kinematics, with effects depending on dental status and type of food.
Supporting Evidence
- Patients with impaired dental status produced a food bolus with a larger particle size than fully dentate patients.
- Chewing time and cycles increased for all groups after surgery, but not significantly for jelly.
- Granulometry of carrot bolus decreased significantly in partially dentate patients after surgery.
Takeaway
This study shows that after weight loss surgery, how people chew their food changes, and this change depends on how many teeth they have.
Methodology
A cohort of 46 obese women was studied, measuring chewing time, cycles, and bolus granulometry before and after surgery.
Potential Biases
Potential bias due to the exclusion of male participants and limited generalizability.
Limitations
The study had a modest sample size and low follow-up rate.
Participant Demographics
46 obese patients (46 women, 8 men) with varying dental statuses.
