The complex intercommunication between the pulpal and periodontal tissues may result in the formation of endodontic periodontal lesions. The relationship between the pulpoperiapical and periodontal microflora explains the possibility of infection spreading between the root canal and the periodontal pocket. The associated tooth has periodontal involvement in the form of either pocket, clinical attachment loss, furcation loss, or other infrabony defects and also pulpoperiapical disease. The diagnosis of endodontic periodontal diseases can sometimes be challenging to make an accurate diagnosis. We report a case of a 34 years old female patient with an endo-perio lesion in the right lower second molar # 47 which was previously treated with endodontic therapy followed by prosthetic rehabilitation. We highlight the need for adequate endodontic management and the importance of maintaining proper prosthetic contour for the prevention of endodontic periodontal lesions. In our case, the endodontic periodontal was the result of inadequate endodontic treatment by the dental clinician. Hence with this case, we reiterate the importance of adequate and complete endodontic treatment and also the need to follow the tooth contours during prosthetic rehabilitation as a preventive protocol for endodontic periodontal lesions.

Research conducted to identify the etiologic features of Class III malocclusion showed that this type of deformity involves not only jaws, but the total cranio-facial complex, making it a difficult anomaly to understand. Majority of patients presenting with Class III malocclusions have a combined skeletal and dental discrepancy, making the factors contributing to this anomaly, complex. In skeletal Class III cases, it is challenging to obtain an esthetically and functionally sound occlusal outcome, only with orthodontic treatment. Furthermore, owing to its high rate of relapse it is difficult to maintain a constant post treatment occlusion. The clinical success of orthodontic mini-screws is dependent on many factors such its material characteristics, biomechanics, surgical technique, clinician’s experience, bone depth and quality, primary stability of the mini-screw and oral hygiene of the patient. However, despite its large-scale application in routine orthodontics, its success rate can be further improved. The present article demonstrates the effect of mini-screws on skeletal class III treatment.
