Endoscopy, Bite Block, Geriatric, Molars


Esophagogastroduodenoscopy (EGD) is an examination of the interior of the esophagus, stomach, and beginning of the small intestine. Upper gastrointestinal (GI) endoscopies are used to diagnose ulcers, cancers, and gastrointestinal tract diseases, as well as to collect biopsy samples. In 2008, over 55 million procedures were performed with GI endoscopic devices [1]. In order to keep the mouth propped open during this procedure, a bite block is used. This bite block ensures that the patient will not bite down on the endoscope during the procedure. Geriatric patients are more likely to have poor dental health due to medications they take, poor dental hygiene, or other underlying conditions. The current endoscopic bite block design places too much force on the anterior teeth, causing them to break. The structural differences between the anterior teeth and the molars [11] mean that the molars are better equipped to distribute the load put upon the teeth from the bite block, due to the fact that molars have more roots, giving them a stronger structure. In order to minimize the instances of tooth fractures in geriatric patients during procedures, the endoscopy bite block needs to be redesigned to ensure patient safety while continuing to protect the endoscope.
