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.

Abstract External root resorption (ERR) of a tooth represents a process in which irreversible damage occurs to solid dental tissues, more precisely of the cement and dentin. External resorption occurs on the root surface or periodontal ligament, and it is manifested by the loss of cement and/or dentine. The prevalence of ERR of the second molar associated with an impacted third molar, based on retro-alveolar radiography and orthopantomography, ranges from 0.3% to 24.2%. The aim of this research was to analyze ERR of the upper and lower jaw associated with the impacted third molar by the application of the Come Beam Computed Tomography. This study included 96 third molars in the upper and lower jaw of a total of 46 analyzed patients’ images. Total prevalence of the second molar ERR associated with the impacted third molar was 8.82%. The second molar ERR was observed in 8 patients (7.84%). Frequency of the second molar ERR in the lower jaw is higher, and it is 8.2%, while in the upper jaw it is only 1% (r = 0.032). Impacted third molars associated with the second molar ERR were most frequently in horizontal (5.1%) and mesioangular (4.1%) position (p = 0.000). The second molar ERR could be avoided by the preventive extraction of mesioangular or horizontal third molars. An adequate decision on the extraction of impacted third molars must be made by the careful assessment of risks and benefits of this surgical intervention. Before the surgical intervention, an adequate care of the second molar, adequate restoration, endodontic treatment or root resection should be done if necessary.

Background and Aim: The third molar tooth lies with symptoms such as periodontal problems, caries, crowding, root resorption, cyst and tumor formation of the adjacent second molar. This study was to evaluate the position of mandibular third molar teeth and its effect on second adjacent molar teeth. Materials and Methods: Panoramic radiography was obtained from 264 patients with mandibular third molar hidden teeth referred to the Birjand School of Dentistry in 2018. The material and direction of their placement and the vertical position of the third molar tooth (based on the PELL & Gregory classification) and its placement angle (based on Winter classification) were determined. Also, the prevalence of distal caries, external root resorption, the amounts of displacement, t inflammatory lesions and the cystic was examined in the adjacent second molar tooth. Data were analyzed using SPSS software (Version 19), and Chi-square statistical test, p-values less than 0.05 were considered as statistically significant. Results: The data from this study showed that most of the wisdom hidden teeth were in Class B and III of Pell and Gregory classification, had Mesial angle based on Winter classification. In 20.8% of patients with caries, there was 3% root canal resorption and 1.1% displacement of the second molar tooth, while no cases of inflammatory and cystic lesions in the second molar tooth were found due to the hidden third molar tooth. The Mesial and horizontal angles of impacted wisdom teeth were associated with increased risk of caries and root resorption of the second molar. Also, Class B's third molar teeth increased caries in second molar teeth. Conclusion: Most pathological problems were observed in Mesial, horizontal, and class B impaction. According to the observed relationship, it seems that the angle and depth of the hidden third molar should be taken into account c when deciding whether or not to extract it.

External Root Resorption

ABSTRACT Aim This study was designed to compare the efficiency of conebeam computed tomography (CBCT) with panoramic radiography to discern external root resorption (ERR) in second molars. Materials and methods This was a retrospective study with a sample size of 50 participants who had a total of 120 impacted third molars visible on panoramic radiographs and CBCT images. The presence of ERR on the neighboring second molar was assessed and the position of impacted third molar was determined using Pell and Gregory classification. The ERR was registered according to Al-Khateeb and Bataineh's criteria. The location and severity were assessed by Ericson et al criteria, and grading of ERR was done as per the criteria given by Nemcovsky. Results The CBCT was able to locate and identify extremely large number of cases with ERR on second molars in comparison with the panoramic radiographs. Based on Pell and Gregory classification, position B was most common. The ERR on second molars was most commonly seen at the cervical region. Most of the cases had mild severity. As per grading mentioned by Nemcovsky, maximum number of cases were given grade A followed by grade B. Conclusion According to our study and considering the threedimensional information obtained from CBCT, we found that ERR was better detected with CBCT. Clinical significance If on panoramic radiographs, a close contact is detected between the second molar and an impacted third molar, CBCT can be advised taking into account the “risk vs reward ratio.” How to cite this article D'Costa ZV, Ahmed J, Ongole R, Shenoy N, Denny C, Binnal A.

Objective: This study sought to assess the frequency and severity of second molar external root resorption (ERR) due to the adjacent third molar and its correlation with the position of third molar and other related factors using cone-beam computed tomography (CBCT). Materials and Methods: This cross-sectional study evaluated 320 second molars and their adjacent impacted third molars on CBCT scans of patients over 16 years, retrieved from the archives of Azad University Radiology Department. Presence/absence of second molar ERR, its location and severity (if present), and position of adjacent third molar were determined on CBCT scans, and recorded in a checklist. Data were analyzed using a logistic regression model. Results: The frequency of second molar ERR was 33.4% in the mandible and 14% in the maxilla. The severity of ERR was significantly correlated with the involved jaw (P=0.001) but had no correlation with age, gender, or depth of impaction of adjacent third molar (P>0.05). The mesioangular and horizontal positions of impacted third molars had a significant correlation with the frequency of second molar ERR (P<0.006). Conclusion: According to the results of this study, ERR occurring in second molars adjacent to third molars is common, especially in the mandible. Mesially inclined third molars have a greater potential of being associated with ERR in second molars.

AbstractThere have been infrequent case reports of bilateral root resorption in the lower second molar secondary from impacted third molar removal with bone regeneration without pain. Root resorption is commonly observed during third molar surgical impaction that affects mandibular second molars. The bone regeneration into the adjacent affected tooth is evident simply after the surgical extraction of the impacted tooth. However, there have been a few previous reports on the prognosis of the remaining resorbed tooth. Most dentists often choose to extract them when damaged if root resorption is observed. This report case involved bilateral root resorption of the lower second molar due to lower adjacent impacted third molar teeth and bone regeneration without pain sensation. After surgical extraction of bilateral lower impacted third molar teeth, the remaining teeth retained vital pulp and survived as functional teeth.
