“…The odd ratio, sensitivity, and specificity of new index and Pederson's index were calculated. Pederson's index had a sensitivity of 0.5, specificity of 0.92 and odd ratio 11.0 compared to new index with sensitivity of 0.85, specificity of 0.92 and 62.3 odd ratio [10]. The positive likelihood ratio for Pederson index was calculated as 6.25 and negative likelihood ratio was 0.543 (Table 3).…”

“…Independent reviews of these 10 articles led to the inclusion of 4 articles ( Table 2) and exclusion of remaining six articles. All of these 4 studies had calculated the sensitivity and specificity of the Pederson's index in the surgery of impacted mandibular third molar [10][11][12][13]. All the variables which were included by Pederson in his index were examined by the authors of these studies.…”

“…All the selected studies had measured the Pederson's index preoperatively and then operating surgeon had compared the intra-operative difficulty with the difficulty calculated by Pederson's index. First study had tested the index in 44 patients [10]. Difficulty of the surgery was decided over the total time taken by the surgeon.…”

“…All the studies included in this review have evaluated the reliability of the Pederson index. Out of the 4 studies, 2 have compared the Pederson index with a new index [10,13]. This new index was based on univariate and multivariate factors selected from radiographs, local anatomy, and demographic variables.…”

The aim of this meta-analysis was to find out the clinical reliability of Pederson index in assessing the difficulty of surgery for impacted mandibular 3rd molar. The relevant articles were selected by Hand search and electronic media (Medline, Pubmed, Embase Cochrane library, ISI web of science) from Jan 2000 to Dec 2010. All the relevant articles were properly screened and findings were extracted from the articles. Pederson index had shown low sensitivity and specificity in predicting the difficulty of surgery for impacted mandibular 3rd molar. Positive and negative likelihood ratio had also shown the unreliability of Pederson index. The meta-analysis of the current literature concluded that Pederson index is not a reliable test to predict the surgical difficulty of impacted mandibular 3rd molar.

ObjectivesThe purpose of present article was to review impacted mandibular third molar aetiology, clinical anatomy, radiologic examination, surgical treatment and possible complications, as well as to create new mandibular third molar impaction and extraction difficulty degree classification based on anatomical and radiologic findings and literature review results.Material and MethodsLiterature was selected through a search of PubMed, Embase and Cochrane electronic databases. The keywords used for search were mandibular third molar, impacted mandibular third molar, inferior alveolar nerve injury third molar, lingual nerve injury third molar. The search was restricted to English language articles, published from 1976 to April 2013. Additionally, a manual search in the major anatomy and oral surgery journals and books was performed. The publications there selected by including clinical and human anatomy studies.ResultsIn total 75 literature sources were obtained and reviewed. Impacted mandibular third molar aetiology, clinical anatomy, radiographic examination, surgical extraction of and possible complications, classifications and risk factors were discussed. New mandibular third molar impaction and extraction difficulty degree classification based on anatomical and radiologic findings and literature review results was proposed.ConclusionsThe classification proposed here based on anatomical and radiological impacted mandibular third molar features is promising to be a helpful tool for impacted tooth assessment as well as for planning for surgical operation. Further clinical studies should be conducted for new classification validation and reliability evaluation.
