Mandibular third molar impaction impose a great dental problem especially to young adults. It is the most commonly impacted tooth in the entire dentition of humans. The cause of impaction may vary and may include lack of space, malposition and physical barrier on the path of eruption. This impaction can lead to different pathologies, from infection to development of cysts. Injury to the inferior alveolar nerve during extraction of mandibular third molar is also a possibility during treatment which can lead to numbness, tingling or burning sensation of the affected side. It can also have adverse effects on the adjacent second molar. Several studies have been done to determine the angulation, depth of impaction, space available between the second molar and ramus, proximity to inferior mandibular third, status of adjacent second molar using several criteria and classification using orthopantomography (OPG) and cone beam computed tomography (CBCT). But there is very little research done on the precision of both OPG and CBCT and comparisons of their diagnostic accuracy. In this study, adults above 21 years of age who have impacted mandibular third molar (IMTM) will be taken for OPG where OPG will provide two-dimensional radiography and CBCT will deliver three-dimensional radiography. Different criteria will be used to assess the status of the impaction and see the sensitivity and specificity in both OPG and CBCT. This study is important to help determine which radiographic diagnostic tool is preferable for assessing the status of impacted third molar and its relation to its surrounding structures and estimate the difficulty index for extraction of mandibular third molar impaction. It will also further help in preventing any injury or complication which can arise to the surrounding structures both during and after extraction and which will also help in achieving best possible outcome for patients.

Objective: To investigate whether the use of cone beam CT (CBCT) changes the diagnosis of external root resorption (ERR) or marginal bone loss (MBL) involving a second molar adjacent to an impacted third molar. Methods: A systematic search was applied in PubMed, EMBASE, Scopus, Web of Science, LILACS, Google Scholar, OpenGrey, and ProQuest. Studies assessing the detection of ERR or MBL in a second molar adjacent to an impacted third molar through CBCT and panoramic radiography (PAN) were included. Prevalence and agreement between PAN and CBCT on the detection of ERR and MBL were collected. The risk of bias was assessed using the MAStARI. Results: A total of 593 papers were identified, and after a 2-phase selection, 5 studies were included in the narrative synthesis. Regarding ERR, its prevalence in PAN was reported from 5.31 to 19.5% and from 22.8 to 62.0% in CBCT. The percentage of agreement varied from 28.5 to 74.0%. The prevalence of MBL varied from 21.9 to 62.9% in PAN, while those values varied from 21.6 to 80% in CBCT images. The percentage of agreement between PAN and CBCT for the detection of MBL ranged from 66.0 to 85.0%. Four studies presented low risk of bias and one had moderate risk. Conclusions: More ERR and MBL are assessed in CBCT compared to PAN. There is a considerable agreement between PAN and CBCT assessment of ERR and MBL, however, mostly related to the absence of the pathology rather its presence.
