“…OPG often overestimates EARR by 20% when compared with periapical radiographs. 9,10 Though three-dimensional imaging modalities like magnetic resonance imaging (MRI) and computed tomography (CT) have provided better visualization, accuracy and greater degree of reproducibility than conventional radiography, their use in routine orthodontic practice is limited due to cost factor and high radiation exposure, as seen in CTs. In addition, trained radiologists are often required for the interpretation of CT images, which further reduces its use in routine orthodontic practice.…”

m e d i c a l j o u r n a l a r m e d f o r c e s i n d i a 7 2 ( 2 0 1 6 ) s 8 -s 1who had undergone treatment with a single phase of fixed orthodontic therapy were randomly selected from institutional archives. The root apices were evaluated for EARR by a single operator on an radiograph viewing box at a standardized source of light using a four-grade ordinal scale. Anterior EARR was measured on the maxillary and mandibular canines. Posterior EARR was measured on premolars, mesiobuccal and distobuccal roots of maxillary first molars and mesial and distal roots of mandibular first molars. The results were compiled and subjected to statistical analysis. Results:The cases in which the patients underwent therapeutic extraction had a relatively higher amount of EARR compared to the cases in which the patients were treated by nonextraction therapy (P < 0.001). Odds ratio indicated that extraction cases had two-fold increased risk of EARR than non-extraction cases (P < 0.001). No statistically significant difference was observed in the distribution of EARR based on gender or duration of orthodontic treatment (P > 0.05).

“…The diagnostic quality of a panoramic radiograph can be impaired in the labial segments due to superimposition of other bony structures and problems with positioning the upper incisors within the focal trough [5]. This may allow abnormalities to remain undetected and it is thus common practice routinely to take supplementary anterior radiographs, as recommended in the British Orthodontic Society guidelines [6].…”

“…Although a few investigators 4,5 and authors of case reports 6–8 have reported that ST are missed on PRs because of the narrow focal trough, in the anterior region of the maxilla, many operators still consider PRs to be important for identifying ST 9,10 . Furthermore, several investigators have used PRs for identifying ST in both surveys and epidemiological studies from which they report their prevalence 11–16 .…”

“…This is why ST can be easily misdiagnosed or unidentified. 3 Although a few investigators 4,5 and authors of case reports [6][7][8] have reported that ST are missed on PRs because of the narrow focal trough, in the anterior region of the maxilla, many operators still consider PRs to be important for identifying ST. 9,10 Furthermore, several investigators have used PRs for identifying ST in both surveys and epidemiological studies from which they report their prevalence. [11][12][13][14][15][16] Nevertheless, there are no reported figures available on the sensitivity and specificity of PRs in identifying ST.…”

OBJECTIVES. To evaluate the reliability of panoramic radiographs (PRs) for identifying supernumerary teeth (ST) and to determine whether the level of dental training of the observer influenced the identification of ST. METHODS. Seventy-five PRs were randomly selected from the patient records and 18 examiners independently rated 25 radiographs each, for specific risk factors as well as for a measure of adequacy. Subsequently, the results were paired with those of the other examiners who assessed the same set of PRs. Descriptive statistics were computed using Fisher's exact test, and kappa statistics were used to assess the inter- and intra-observer reliability. RESULTS. Four hundred and fifty PRs were available for analysis. The overall sensitivity and specificity figures were 50% and 98.3%, whereas the positive and negative predictive values were 90.6% and 83.6%, respectively. The sensitivity figures for Junior House Dental Officers and Postgraduate Paediatric Dental Trainees were 39.2% and 60.8%, whereas the specificity figures were 99.4% and 95% with slight inter-examiner and moderate intra-examiner reliability. CONCLUSIONS. Panoramic radiographs are unreliable for identifying ST, and higher level of dental training is essential for identifying ST.
