BackgroundThe loss of anterior tooth leads to a volumetric deficit of soft and hard tissues, which causes an altered topography. This localized alveolar ridge defect in turn complicates the prosthetic rehabilitation and un-esthetic result might lead to patient’s social stigma. Such defects can be corrected by either soft or hard tissue augmentation, along with esthetic prosthesis.Case presentationThis case report describes the augmentation of the sub-epithelial soft tissue graft to rebuild the lost gingival contour for prosthetic rehabilitation missing tooth in esthetic region. The surgical “trap door” approach is explained in detail along with procedure to introduce innovative E pontic design in prosthesis.ConclusionThe ultimate goal of any prosthetic treatment is to enhance esthetics of patient thus aiding in his/her psychological health along with functional stabilization of the compromised arch. The periodontal surgery with gingival friendly prosthetic design increases esthetic outcome of the treatment.

In this study, total of 60 extracted human teeth were divided into four groups. Group I and II were subjected to LCU A (2550 mW/cm2) and Group III and IV to LCU B (700 mW/cm2), respectively. The increase in temperature level from baseline was recorded using K type thermocouple while curing of dentin bonding agent and composite resins. The temperature rise was significantly higher for Light Curing Unit A which had higher intensity light than Light Curing Unit B. Remaining dentin thickness of the prepared tooth also has significant role in the temperature rise. Hence, light curing units should be used with caution to avoid over‐exposure of teeth. Dental practitioners need to prepare teeth with silicone indices and pre‐assessment of radiographs to avoid over‐preparation. Regular check of intensity of light curing unit using commercially available intensity meter is advocated.

Aim and Objective: Endodontic retreatment is indicated in the event of a failure of initial treatment of the root canal and of an initial treatment that looks to be correctable with retreatment. This in-vitro study was designed to assess the efficacy of passive ultrasonic irrigation in endodontic retreatment, by employing scanning electron microscopes, on the cleanliness of dentine tubules with and without solvent in curved root channels. Material and method: Sixty human maxillary molar teeth were treated endontically. The protaper rotary instrument was used in root canals in the crown down procedure under copious 3% NaOCl (2 ml) and Glyde irrigation. The saline solution (1 ml) was used for final rinsing. The 10 sample root surfaces of each group were evaluated for SEM pictures. Results: Amongst group I and II here were more open dentinal tubules that were statistically significant (p<0.05) in Group II without solvent group. Group IV demonstrated larger, statistically significant open dentinal tubules between group  III and IV. The most dentinal open tubules were found in Group IV among the four groups.
