Unerupted teeth associated with dentigerous cysts and treated with coronectomy: mini case series

The aim of this systematic review was to evaluate the clinical effectiveness of the surgical technique of coronectomy for third molars extraction in close proximity with the inferior alveolar nerve.A literature survey carried out through PubMed, SCOPUS and the Cochrane Library from inceptions to the last access in January 31, 2014, was performed to intercept randomised clinical trials, controlled clinical trials, prospective cohort studies or retrospective studies (with or without control group) that examined the clinical outcomes after coronectomy. The following variable were evaluated: inferior alveolar nerve injury, lingual nerve injury, postoperative adverse effects, pulp disease, root migration and rate of reoperation. Ten articles qualified for the final analysis. The successful coronectomies varied from a minimum of 61.7% to a maximum of 100%. Coronectomy was associated with a low incidence of complications in terms of inferior alveolar nerve injury (0%-9.5%), lingual nerve injury (0%-2%), postoperative pain (1.1%-41.9%) and swelling (4.6%), dry socket infection (2%-12%), infection rate (1%-9.5%) and pulp disease (0.9%). Migration of the retained roots seems to be a frequent occurrence (2%-85.3%).Coronectomy appears to be a safe procedure at least in the short term, with a reduced incidence of postoperative complications. Therefore, a coronectomy can be indicated for teeth that are very close to the inferior alveolar nerve. If a second operation is needed for the remnant roots, they can be removed with a low risk of paresthesia, because the roots are generally receded from the mandubular nerve.

“…The sample size of patients undergoing corononectomy ranged from a minimum of 21 subjects [ 60 ] to a maximum of 171 subjects [ 17 ] and the mean age was included between 27.2 years [ 17 ] and 41.3 years [ 60 ]. Only four studies considered a control group [ 7 , 16 , 17 , 24 ].…”

“…The increased interest in coronectomy could be partly attributed to its applicability to treat patients with a high risk of injury to the inferior alveolar nerve or lower third molars associated with a dentigerous cyst. 33,34 Moreover, in recent years there have been more studies that have assessed the safety of coronectomy and randomized clinical trials that have evaluated the reduced risk to nerve injury by coronectomy. 3,[5][6][7]35 Two of the top 10 most cited coronectomy papers were randomized clinical trials.…”

Aim The aim of the present bibliometric study was to analyze the citations received by coronectomy papers and their references. Methods Data were extracted from the Web of Science online database. After excluding irrelevant papers, full record and cited references from 79 papers were downloaded and imported into VOSviewer and CRExplorer for bibliometric analyses. Results The 79 papers on coronectomy collectively had 9.7 citations per paper. The h‐index of this collection of papers was 17. The top five major contributing countries were the UK (N = 20, 25.3%), the USA (N = 10, 12.7%), Italy (N = 9, 11.4%), China (N = 5, 6.3%), and Turkey (N = 5, 6.3%). The top two major contributing journals, Journal of Oral and Maxillofacial Surgery and British Journal of Oral and Maxillofacial Surgery, together accounted for more than half of the 79 papers (N = 43, 54.4%). Conclusions Papers dealing with postoperative morbidity topics had high citation counts in general, such as dry socket (27.4 citations per paper), infection (24.6 citations per paper), and safety (35.5 citations per paper). Citation per paper correlated with publication count at the affiliation level, but not at the author, country, and journal levels.

“…Although a fairly large defect may be left, this does not seem to require any type of grafting in most cases. 22 No authors currently recommend any type of endodontic treatment of the retained roots, 23 and articles have shown that the retained roots do remain vital. 24 Other areas showing differences in techniques are discussed next.…”
