Although pressure resorption of second molars is associated with impacted and/or erupting third molars, the relationship between pressure resorption and age is unclear. In order to investigate this relationship, 3883 dental radiographs were studied in 3174 individuals of various ages. The incidence of superimposition of the second molar on the third molar was not elevated in any subgroup except that of women of 16-40 years of age. There were no age or sex differences for the incidence of second molar root resorption. In older individuals, root resorption associated with a completely impacted third molar was more frequent than with a partially impacted third molar, and root resorption at the apex was mainly seen in individuals over 50 years of age. There was a higher incidence of superimposition and root resorption in men than women. Apical root resorption may be seen long after the formation of completely impacted third molars in both genders.

“…Questo sembra essere il più probabile prerequisito perche si inneschi il processo di riassorbimento. [16][17][18] Tale carenza di tessuto cemento-cementoide permette il contatto diretto tra dentina e le cellule del potenziale riassorbimento del parodonto. Diverse sono le teorie che ipotizzano l'attivazione del riassorbimento e l'invasione di questo tessuto fibrovascolare: un gruppo di studiosi ipotizzano che la presenza di microrganismi sulculari possano rappresentare i fattori attivanti; 10,19-22 l'ipotesi si basa quindi sul fatto che soltanto dopo un'attivazione di mediatori dell'infiammazione si ottiene lo sviluppo di tessuto di riassorbimento in zone con tessuto radicolare esposto.…”

Aim: Theme of this report is the external cervical root resorption and the sequence of clinical procedures to be implemented during the phases of treatment.The external cervical root resorption (ICR) presents particular pathological conditions such as to classify between resorption of inflammatory origin. 1-3 It is generally presented as a complex clinical situation both in the diagnosis in a predictable prognosis. 3-6 It's often associated with loss of calcified tissue: dentin, cementum, alveolar bone. Often during the treatment the pulp vitality is compromised. [4][5][6][7][8][9][10][11] The etiological factors are vague and not closely associated with the onset of the disease. Prevention is often impossible and treatment modalities not so simple, highly dependent on the location and severity of the injury. 2,3 Key points to get a favorable prognosis of elements with the processes of resorption are: early detection, accurate removal of tissue resorption, endodontic and restorative phases with accurate isolation of the operative field.In the early stages of treatment it is advisable to look for: the specific etiological factor (bleaching, trauma, previous surgery, etc.), the severity of the lesion (extension submarginal, infraosseus; the possible compromise of the vitality of the pulp by means of diagnostic vitality tests. 12,13 A large part of the cervical resorption is not associated with endodontic problems. A conservative approach without sacrificing the vitality of the pulp is then desirable. 8 Cleansing with irrigation endodontic solutions (sodium ipocloroite and clorexidine) can prevent future endodontic diseases. 14 Peer review under responsibility of Società Italiana di Endodonzia.

“…15 Physiologically, it is noted when the primary dentition exfoliates. 15 The known risk factor for tooth resorption is the mechanical force due to the superimposition of the third molar, and the inflammation of the periodontium may further complicate the condition 16 or might even secrete the inflammatory mediators that assign the osteoclast toward resorption of the mineralized tissue by stimulating the reduced dental epithelium of the impacted tooth. 17,18 External root resorption usually does not present with any signs and symptoms.…”

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."
