The clinical importance of this study was that it allowed us to know the direct impact that bleaching agents with and without calcium have on dental structures.

The aim of the study was to compare the platelet-rich fibrin (PRF) and titanium-prepared platelet-rich fibrin (T-PRF) in the management of endo-perio lesions. This study was conducted with 140 patients who are affected by endo-perio lesions, and the patients were divided into two groups. In group I, patients were treated with PRF, and in group II, patients were treated with T-PRF. Endodontic treatment was done in all cases, following a standardized aseptic method. Probing pocket and relative attachment level were recorded after 3 months and 6 months in both groups. After 3 months, the mean change of probing pocket depth (PPD) was 68% in group I and 33.41% in group II. The intergroup distinction was not significant ( > 0.05), whereas the intragroup evaluation was significant ( < 0.05). The mean change after 6 months was 42.59% in group I and 43.90% in group II. The difference was not significant ( > 0.05). After 3 months, the mean% change of relative attachment level (RAL) was 31.20% in group I and 31.60% in group II. The intergroup distinction was not significant ( > 0.05), whereas the intragroup evaluation established a considerable discrepancy ( < 0.05). The mean change after 6 months was 40.82% in group I and 42.12% in group II. Both PRF and T-PRF were effective in inducing a reduction in pocket depth and useful in gaining attachment level. With the use of PRF and T-PRF, the complex case of endo-perio lesions can be efficiently managed. With the use of PRF and T-PRF, the complex case of endo-perio lesions can be efficiently managed. To evaluate the effect of the differences in the dimensions of maxillary lateral incisor on the esthetic perception of smile among dental professionals and the general population. Two sets of photographs where the maxillary incisor dimensions were modified using computer software (Adobe Photoshop) were created. In the first set, six images were included where the maxillary lateral incisor width was modified. The second set included five images where only the maxillary lateral incisor length was modified keeping the gingival margins same. Three groups of participants formed the sample. Hypodontia patients formed the first group, non-hypodontia patients formed the control group, while the dentists constituted to the third group. A total of 156 participants were recruited, 36 patients with radiographically confirmed hypodontia out of which 22 were female and 14 were male, 54 non-hypodontia "control" patients out of which 29 were female and 24 were male, and 66 dentists out of which 39 were female and 27 were will help us understand the different perceptions of the patients and the dentists on esthetics, which would further help us in planning the treatment accordingly. The aim of the study was to compare the healing and osseous regeneration of mandibular third molar extraction sockets with and without platelet-rich plasma (PRP) with the evaluation of clinical objectives such as pain, swelling, trismus, soft tissue healing, pocket depth distal to second molar and radiological evaluation of the bony density in the postextracted third molar socket. In this prospective study, 100 patients were selected by the random sampling method from the outpatient department of oral and maxillofacial surgery in the year 2016-2017. Patients were equally allocated into intervention (transalveolar extraction followed by PRP placement) and nonintervention (transalveolar extraction without PRP placement) group as group I and group II, respectively, and evaluation parameters were considered accordingly. The statistical analysis was done using SPSS (Statistical Package for Social Sciences) Version 15.0 (IBM, USA) statistical analysis software. The pain score of patients of group I (non-PRP) sity, healing process, and improvement in the pain and swelling, and there was a definite reduction in trismus and periodontal probing depth after the impacted mandibular wisdom teeth extraction. The use of PRP application increases the bone density, healing process, and improvement in the pain and swelling, and there was a definite reduction in trismus and periodontal probing depth after the impacted mandibular wisdom teeth extraction. To evaluate the push-out bond strength of resin-based sealer to root dentin after a final flush of three different irrigants. Thirty extracted human mandibular premolars were sectioned 4 mm below the cement-enamel junction and 60 horizontal disks of 2 mm from middle one-third of the root were prepared. https://www.selleckchem.com/products/AZD2281(Olaparib).html The disks were immersed in 3% sodium hypochlorite for 1 minute, and after drying the disks, they were finally flushed with the following irrigants group I-Chitosan solution, group II- juice (MCJ), and group III-ethylenediaminetetraacetic acid (EDTA). The disks were filled with AH Plus sealer, and after 7 days, the disks were subjected to push-out bond strength using a universal testing machine. EDTA had the highest push-out bond strength followed by MCJ and then chitosan. Chitosan and MCJ can be used as alternative irrigants as a final flush during the cleaning and shaping of the root canals. EDTA, chitosan solution, and MCJ are efficient in smear layer removal which thereby increases better sealer penetration and prevents the dislocation of obturating materials.

To compare the condyle sagittal position of class I and class II division 2 in orthodontic patients. Fifty orthodontic cases (30 females and 20 males; 12-31 years) from the records of an Orthodontic Graduate Program were collected. Such cases presented cone-beam computed tomography (CBCT) as part of their initial diagnostic examinations. The study sample constituted two groups, class I and class II division 2 groups. A previously calibrated examiner performed the measurements of the images, representing the distance between the condyle and the articular surface of the glenoid fossa, both anteriorly (anterior disk space-ADS) and posteriorly (posterior disk space-PDS). Descriptive statistics were performed. Data were normally distributed, and parametric tests were used. Paired sample test was used to identify differences between the right and the left joints. Differences between class I and class II/2 groups were tested using independent test. All statistical tests were interpreted at 5% significance level.
