Bitewing film quality : a clinical comparison of the loop vs. holder techniques . OBJECTIVE To compare in vivo bitewing film quality using the holder versus the paper loop technique . METHOD AND MATERIALS Four bitewing films were taken from the right and left premolar and molar regions of 45 dental students using both the bitewing holder and paper loop techniques . A total of 360 films were taken and assessed by an experienced practitioner not apprised of the bitewing technique used . Of interest were : ( 1 ) the number of overlaps and the percentage of teeth showing the alveolar crest ; ( 2 ) proper film positioning ; and ( 3 ) the percentage of cone cutting . A Poisson regression using generalized estimating equations ( GEEs ) was used to estimate the difference in overlap between the two techniques . For proper positioning and cone cutting , logistic regressions using GEEs were used . RESULTS The average number of horizontal overlaps for the loop and holder techniques at the right premolar , right molar , left premolar , and left molar were 1.64 , 2.11 , 2.16 , 2.78 , and 1.64 , 2.00 , 2.00 , 2.18 , respectively . The loop technique was 1.11 times more likely to cause overlapping than the holder technique . The highest percentage of teeth showing the alveolar crest by the loop technique was 97.8 % in the mandibular second premolar and first molar . With respect to film positioning , the loop technique was 1.12 times more likely to cause improper positioning than the holder technique . Both techniques demonstrated minimal cone cutting ( 1 in the loop versus 0 in the holder ) . CONCLUSION The quality of bitewing films taken by the loop and holder techniques was not significantly different .
