Excluding the fourth series, error rates did not differ between the groups, so observed differences in bitewing film
orientation did not seem to influence study outcomes.
Pediatric bitewing film
holder: preschoolers' acceptance and radiographs' diagnostic quality.
Kodak Ultra Speed dental film (EP21, size 2), held in bitewing film
holders (Hawes-Neos, Bioggio, Switzerland) were used in combination with an Espectro II 50 kV, 10 mA machine (Dabi Atlante, Ribeirao Preto, SP, Brazil).
Other useful film-holding instruments are hemostats and similar clamp-type devices, disposable paper tabs for bitewing film
placement and disposable Styrofoam film holders for taking periapical radiographs.
One set of prongs is color-coded red; the insertion holes of the red bitewing film holder connect into both of these prongs when taking bitewing radiographs.
The bitewing film holder would be oriented in the mouth so that the film-holding plane is located between the tongue and the lingual aspect of the teeth being imaged.
The assistant orients the film so that the white side of the film faces the flat horizontal plane of the bitewing film holder.
Technically, this bitewing XCP assemblage is incorrect, but it may result in acceptable bitewing films. Here, the film is placed into the film holder so that its white side faces away from the flat horizontal plane of the film holder.
Cone cuts are common on bitewing films
when it is hard to see the film.
Even in the apparent absence of caries or periodontal problems, the possibility of discovering lesions such as the odontoma or other abnormalities warrants exposing radiographs beyond a simple set of bitewing films
. The dental hygienist should thoroughly evaluate all areas in the survey, beyond bone level and caries, noting changes in trabecular patterns of bone, as well as other abnormal radiolucencies and radiopacities.
A full-mouth series consisted of 14 periapicals and 4 horizontal bitewing films
