“…No unpublished manuscripts were identified. Of the 108 articles, 10 were considered to be potentially relevant [4][5][6][7][8][9]. Independent reviews of these 10 articles led to the inclusion of 4 articles ( Table 2) and exclusion of remaining six articles.…”

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.

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.

“…Informed consent relies upon an appropriate assessment of the likely extent of surgery based on the clinical and radiographic findings such as depth, degree of impaction, ramus relationship/space available, width of root or a combination of these factors. 7 A number of indices to determine the degree of difficulty have been devised to attempt to address this issue. [7][8][9] However these do not take into account patient factors that are also important variables.…”

Objective To investigate the indications for and anticipated difficulty of third molar surgery between two different referral settings. Design A prospective study involving completion of a proforma pre-and post-operatively. Setting A dental teaching hospital and a specialist surgical dentistry practice in 2003. Subjects and methods Patients referred for the assessment of their third molars were recruited. Details of the clinical and radiographical assessment for each patient were recorded pre-operatively and the extent of surgery required post-operatively. Results The main indication for referral for third molar extraction was pericoronitis in both centres. A larger number of patients were assessed and treated in a shorter period of time at the surgical dentist compared with the dental hospital. The surgical dentist was accurate in his assessment of the difficulty of surgery 96% of the time compared with 66% for the dental hospital staff.
