“…The majority of literature to date focuses on the identification of 1 pathology, often the detection of caries or a solitary study on the adjustment of working length, based on 1 radiographic view. [1][2][3][4][5][6] Our study is the first to test for the interpretation of a myriad of pathologies and imaging based on university-determined clinical competencies. This paper, also uniquely, sought to compare peer-to-peer performances specifically between clinical students separated only by 1 year of training rather than peer-to-faculty.…”

Purpose To evaluate and distinguish if an additional year of clinical experience increases the cognitive ability of dental students to accurately assess and interpret dental radiographs. Methods Radiological acuity was assessed between two groups of clinical dental students at Penn Dental Medicine (PDM). Group 1 was composed of 147 third‐year dental students (D3), group 2 was composed of 145 fourth‐year dental students (D4). A 65‐question test comprising the length and breadth of radiographic anatomy and pathology was administered to both D3 and D4 students. The test was designed to test the participants' knowledge of radiographic technique, anatomy, and differential diagnosis. The null hypothesis was that there would be no significant differences between the two groups. Results STATA 15 software (StataCorp LLC, College Station, TX, USA) was used to statistically analyze the findings. Although, the mean correct score for group 1 was higher (60/65) than group 2 (59/65), there was no statistically significant difference between the performance of the groups. On average, group 1 outperformed the clinically more experienced group 2 on an individual question basis. The average overall number of correctly answered items compared to incorrectly answered items reflected this difference. Conclusion(s) An additional year of clinical dental education does not appear to correlate with any higher radiographic acumen. This may be due to tapering exposure to unique pathology and findings, as more routine findings are encountered daily and classroom instruction during the fourth year of dental school is limited. Early incorporation of new radiographic education tools that are clinically oriented may be one method to increase retention of knowledge accumulated in the initial didactic years of dental education.

D uring root canal treatment, canal preparation and obturation should stop at the cementodentinal junction. However, the stop location is detectable only histologically. [1] Determining the endodontic apical stop is a crucial step in canal treatment, and the success or failure of the treatment depends on correctly identifying the stop location. [2] Several methods for determining the length are now available, and the best known approach was reported by Kuttler. [1] The method recommends a canal preparation at 0.5 mm from the radiographic apex, and the apical constriction is, on average, located at this distance from the anatomical apex. However, the anatomy of this area is by definition different for each individual, and stopping the preparation to an estimated level does not allow for the evaluation of the remaining channel length.For a long time, X-rays remained essential for determining endodontic apical stops. However, estimates obtained from X-rays are considered approximate and biased. [3] X-ray images alone cannot precisely determine the Objective: To determine the variability in the distance between apical constriction determined by an apex locator and the radiographic apex on digital radiographs in a Moroccan population.Methods: Once the apex locator indicated the position of the apical constriction marked by 0.5, an existing lime X-ray was taken and measurements were made using the Kodak Dental Imaging Software 6.10.8.3. Results:The average distance between the tip of the instrument and the radiographic apex (DTIRA) was 0.792 mm + 0.61. The position of the apical constriction at 0.5 mm of the radiographic apex is in only 21% of selected teeth. Ninety eight out of 100 teeth had a DRLAAR of <2 mm. Considering these 98 teeth, 40.8% of them had a DTIRA in the range of 0-0.5 mm, 38.8% in the range of 0.5-1 mm, and 20.4% had DTIRA of >1 mm. Conclusion:There is a great variability in the distance between the apical constriction determined by an apex locator and the radiographic apex on digital radiographs in this population. Indeed, the subtraction of 0.5 mm from the latter, as recommended by several authors, is in only 21% of selected teeth.

Influence of clinical experience on the radiographic determination of endodontic working length

Abstract: Clinical experience after graduation influenced the accuracy of estimating the adjustments needed for correct radiographic WL of single-rooted teeth. The most experienced group was significantly more accurate than the other groups.
