CH. 24
Imaging of Patients with Special Needs
| Term | Definition |
|---|---|
| Exposure sequence does play a role in preventing gag reflex endodontic patient | patient who has undergene root canal treatment or disease of dental pulp with in tooth |
| psychogenic stimuli | stimuli originating mind |
| tactile stimuli | stimuli originating from touch |
| areas of oral cavity most likely to elicit the gag reflex is | posterior or lateral 3rd of tongue and soft palate |
| most common examination often used in endentulous patients is | panoramic |
| What size receptor is used for endentulous examinations | size 2 |
| MD central incisors, MX and MD first molars erupt at what age | 6-7 |
| MX central incisors, MD lateral incisors erupt at what age | 7-8 |
| MX lateral incisors erupt at what age | 8-9 |
| MD canines erupt at what age | 9-10 |
| MX canines, MX and MD premolars erupt at what age | 10-12 |
| MX and MD 2nd molars erupt at what age | 11-13 |
| Lack of operator confidence may act as a psychogenic stimulus and contribute to gag reflex | |
| The longer a receptor stays in the mouth the more likely a patient is to gag | |
| Anterior pariapical projections are always exposed first before posterior pariapical projections because of less gagging | |
| Receptor dragged along palatal tissues may stimulate gag reflex | |
| DA shouldn’t ask ask patient is they “are a gagger” | |
| If patient gags, DA should remove receptor as quickly as possible and reassure patient | |
| If patient is breathing during receptor placement and exposure the gag reflex will not occur | |
| Distracting patient often helps suppress gag reflex | |
| If dental radiographer determines that a person can’t tolerate intraoral projections, no intraoral projections/receptors should be exposed | |
| It’s not appropriate for DA to ask personal questions about patients disabilities | |
| With pediatric patients DA must alter patient management techniques | |
| During endodontic procedure, receptor placement is difficult because of poor visualization of tooth | |
| If panoramic x-ray unit isn’t available | 14 pariapical projections can be used to examin endoentulous arches |
