The sample of 200 students was selected by Simple Random Sampling Method in the age group between 21 to 25 years.  Intraoral periapical radiographs of right and left mandibular third molars were taken and clinical examination was done to assess the presence of pericoronitis, periodontal pocket, proximal caries, root resorption in distal surface of second. On clinical examination, 23% of pericoronitis was present, 12% of periodontal pockets, 8% proximal caries and no resorption were observed. Within the limitations of this study, it was concluded that significant relatively less impact of mandibular third molar on second molars.  Further studies are recommended with increased sample size. https://biomedpharmajournal.org/vol8octoberspledition/evaluation-of-the-impact-of-impacted-mandibular-third-molars-on-surrounding-structures-a-clinical-and-radiographic-analysis-in-students-of-tagore-dental-college-and-hospital/ Evaluation Impact Mandibular Third Molars Surrounding Structures Clinical Radiographic Analysis Students Hospital
