Aim This clinical study was undertaken to evaluate the postoperative sequelae following single-visit versus multiplevisit endodontic therapy at various interval of time in vital as well as nonvital teeth. Materials and methods Thirty-two cases were randomly assigned to the following four groups, group I, group II, group III and group IV. After gaining the access to the pulp chamber, establishing the working length, thorough cleaning and shaping was done for all the cases. Obturation was done by protaper (variable taper) gutta-percha and AH-PLUS sealer using lateral and vertical condensation technique. All the cases were recalled after 48 hours, 1 week, 4 weeks and 6 weeks following obturation and were evaluated for postoperative pain, tenderness and swelling. Results There was no statistically significant difference amongst all the four groups in the incidence and severity of postoperative pain, tenderness and swelling at the end of one week. However, within 48 hours groups I, II and IV showed more pain when compared to group III. And groups I, II and III showed more tenderness compared with groups IV. Postoperative swelling was not reported. Radiographic investigation at the end of 6 weeks showed significant change in the appearance of the periapical region in group II and group IV cases. Conclusion On strict adherence to biological principles and proper case selection, no significant difference in the success, postoperative pain and tenderness exist when treated with either single-visit or multiple-visit therapy. Clinical significance No significant difference in the success rate or postoperative pain, tenderness, and swelling exists when treated with either single-visit or multiple-visit endodontic therapy. Hence, one can readily integrate one-visit endodontic therapy into the routine clinical practice of dentistry. How to cite this article Prashanth MB, Tavane PN, Abraham S, Chacko L.

Objective: The objective of this study is to evaluate the vertical root fracture resistance of endodontically treated teeth obturated with-Tubli-Seal EWT/Gutta-percha, AH Plus/Gutta-percha, Epiphany SE sealer/Epiphany point. Study design: Sixty-five single rooted premolars were decoronated and root length was 14 mm for each specimen. Fifty five teeth were enlarged up to ISO size 40 master apical file with stainless steel K-files using standardized preparation and remaining ten teeth were served as negative control. Then teeth were randomly assigned into different groups depending on sealer used for obturation as follows: Group 1: Negative control-no instrumentation was performed. Group 2: Positive control-gutta-percha with out the use of any sealer. Group 3: Experimental group-gutta-percha and Tubli-Seal EWT root canal sealer. Group 4: Experimental group-gutta-percha and AH Plus. Group 5: Experimental group-epiphany SE sealer and epiphany points. After 72 hours, the specimens were embedded in autopolymerizing resin leaving 7 mm of each root exposed and were subjected to fracture testing under universal testing machine at a crosshead speed of 1.0 mm per minute until the root fractured. Results were statistically analyzed using one-way ANOVA and independent t-test. Results: Showed that Epiphany SE sealer/Epiphany points showed highest mean fracture resistance and Tubli-Seal EWT group showed the least fracture resistance of all the materials tested. There was no statistically significant difference among experimental groups. Conclusion: Epiphany SE sealer/Epiphany points demonstrated highest fracture resistance values than the other materials tested and intact tooth had highest resistance against vertical root fracture. Clinical significance: Epiphany SE sealer/Epiphany points may be one of the materials of choice in the endodontic treatment of teeth.

Cosmetic dentistry has gone through potential transformations over the years. Various techniques have now been established to analyze the smile digitally and, to simulate the "Before and After" in a particular case. Selfiedontics defines the amalgamation of selfie-culture with clinical practice of dentistry. Use of selfie should not only be restricted to social platform, but also to educate the patient about his own dental status, and even in treatment planning. This article focuses on the combination of digital dentistry with that of the cosmetic or esthetic dentistry.

Aim This study was carried out with the purpose of comparing three impression methods as to which of them placed tissues most favorably. Methods The methods used were Hindels method, selective tissue placement method and functional reline method. The measurements obtained were analyzed to determine which of the three impression methods placed the mucosal tissues maximally. To compare and measure tissue placements, autopolymerizing acrylic resin platforms were constructed to the height of the occlusal surfaces of the remaining teeth. 15 orthodontic buccal tubes were placed on each side of the platform. They were arranged in three sets of five and attached to the platform over selected reference regions by means of autopolymerizing resin. The selected reference areas were in anterior, middle and posterior areas of the ridge on either side. Results No significant difference was seen in tissue placement in the anterior middle and posterior regions in each of the three methods when each method was assessed separately. Selective tissue placement method placed the tissues maximally (7.547 mm) followed by Hindels method (7.2110 mm) and the least placement was by functional reline method (5.856 mm). Tissue placement was significantly higher in Hindels method as compared to functional reline method (p < 0.001). Conclusion Tissue placement was maximum in the posterior region, followed by the middle region and least in the anterior region of the mandibular ridge for all three methods. Selective tissue placement method showed the maximum overall tissue placement followed by the Hindels method and minimum placement was by functional reline method. Clinical significance Selective tissue placement method provided maximum overall tissue placement and can be a preferred technique for impression making for bilateral distal extension removable partial denture fabrication.
