Abstract:

Purpose:

This study compares bitewing radiograph quality using three positioning devices.




Methods:

A Rinn DXTTR was affixed to a dental chair and an endotracheal tube was placed in the oral cavity and taped to the right commissure. Bitewings were captured using an intraoral bitewing tab, a Rinn positioning device, and a rectangular collimator attachment with corresponding positioning device. Radiographs were taken using a handheld Nomad. The radiographer was instructed to capture pre-molar bitewings including the distal of the canines. Radiographs were assessed for presence of overlap and the distal surface of canines. The data was analyzed using un-paired T-Tests.




Results:

105 right and left bitewings were obtained. There was a significant finding that the extraoral positioning devices were more successful at reducing overlap (Rinn system: P< .05; rectangular collimator system: P< .05). The intraoral positioning device and Rinn system were significantly better at capturing the distal of the canines compared to the rectangular collimator system (P < .05; P< .05) and there was no significant difference between the intraoral positioning device and the Rinn system (P >.05). There was no significant difference found when comparing the quality of right versus left bitewings (Overlap: P >.05; distal surfaces of canines: P >.05).




Conclusion:

Extraoral positioning devices produced higher quality bitewing radiographs by reducing overlap in the simulated pediatric dentition. The endotracheal tube position did not reduce the quality of bitewing radiographs.
