“…Authors mentioned that not all significant predictors of surgical difficulty should be considered indicators of complications. Akadiri and Obiechina [64] demonstrated in their study wisdom tooth depth angulation and root morphology as the most consistent determinants of extraction difficulty. …”

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.

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.

“…A study by Lago-Méndez et al found both these factors to be reliable, statistically significant measures and the best way to predict surgical difficulty [19]. The surgery time is considered to be the gold standard in determining the surgical difficulty [4,11,15,18,19]. In our study, we have considered time taken for tooth removal (surgery time) to be the gold standard for determination of the surgical difficulty against which we have compared the conventional Pederson's Index and our proposed New Index.…”

Objective The aim of the study is to assess the clinical and radiological factors that increase the surgical difficulty in removal of mandibular impacted 3rd molar and design a new difficulty predictive index. Methods The data was collected from 100 patients with impacted mandibular 3rd molar who presented to Department of Oral and Maxillofacial Surgery, K.L.E's Institute of Dental Sciences. Clinical and radiological parameters included in the New Index were noted. The tooth was then removed under local anesthesia and time taken for the removal was noted. The Pederson Index, New Index and time taken were co-related using kappa statistical analysis. Results The kappa agreement between Pederson Index and time taken was 66.50 % (0.2231) whereas between New Index and time was 89 % (0.7177) indicating that New Index is a better predictor of the difficulty. Conclusion The New Index is a reliable tool in predicting the difficulty in the removal of mandibular impacted third molar.
