Background: Assessment is a crucial step in the educational process and is the driving force behind learning. Formative assessment (FA) is a relatively new concept in assessment methods. By applying Blooms taxonomy (BT), which describes developmental progression for knowledge in FA, we can drive deeper learning. We were interested to know if by framing multiple choice questions (MCQ) using BT model and using it as a tool for FA will help to reinforce learning among first year MBBS students. Materials and Methods: All 150 MBBS students taking biochemistry classes were subjected to MCQ tests at the end of series of lectures and an internal exam (T3). MCQ s were framed by applying BT testing at all levels of cognition domain. Pearson's correlation coefficient of marks before and after the intervention was calculated. Mean scores were analyzed using students paired t-test. Feedback was analyzed for students' perception regarding the assessment method. Results: Comparison of mean scores in T3 with average of T1 and T2 showed P value of >0.0001. Only 28.7% students got <50% marks when assessed after FA as compared to 46% students before using FA. Analysis of students' perception indicated a high level of acceptability and motivation toward incorporation of formative assessment. Conclusion: Introduction of MCQs as a tool for formative assessment at the end of each lecture helps to reinforce learning in first year medical students. This study demonstrates the need for using the BT model, which tests knowledge at various levels of cognition in FA pattern.

Background: Good implant stability is the prime concern for successful prosthetic rehabilitation. Many methods and different types of implants have been used to achieve primary and secondary stability with varying success rates. The evolution continued with the use of biological materials for early osseointegration. The present study was aimed to compare and evaluate the effect of platelet rich plasma (PRP) on the early osseointegration and secondary stability of dental implants using implant stability values. Materials and Methods: A total of 18 dental implants were randomly placed among 10 patients in the mandibular posterior region using split mouth design. In the control group, implants were placed following standard surgical protocol. In the study group, autologous PRP was used to moisten the implants before placement. Implant stability was observed and compared using Osstel Implant stability meter at 0, 30, 60, and 90 days. All the cases were followed-up over period of 18 months. Statistical analysis was carried using one-way analysis of variance and paired and unpaired t-test. Results: Significant difference in stability values were observed in the study group following 30 days after implant placement. Control group showed no statistically significant difference at all time intervals. Implant stability values were higher in the early phase of osseointegration in the PRP group. However, at the end of the study period, both groups showed similar stability. Conclusion: Good primary implant stability is beneficial for early loading and rehabilitation. PRP can be successfully used as an adjunct for better and early function. It is safe due to its autologous origin, thus eliminating the risk of disease transmission and immunogenic reactions.

The spine is a complex and vital structure. Its function includes not only the structural support of the body as a whole but it also serves as a conduit for safe passage of the neural elements while allowing proper interaction with the brain. We report the case of a 7-year-old child who presented with a swelling in the posterior aspect of the neck. On lateral radiograph, there was elongated spinous process in the neck. Computed tomography examination better depicted this congenital variant and clearly showed giant spinous process of the C5 vertebrae. There was associated spina bifida at this level. Moreover, there was asymmetrical fusion of the posterior elements at C2, C3, and C4. Magnetic resonance imaging showed normal signal intensity of cervical cord. This is a very rare congenital anomaly. Very few cases have been reported previously.

Avulsion or exarticulation is one of the most severe injuries of the tooth, frequently encountered in young children and the maxillary anterior teeth. Immediate transplantation of the avulsed tooth is the suggested treatment that results in a favorable prognosis, although this may not be possible every time. Here, we present a case report of an 8-year-old girl who sustained an avulsion injury of the maxillary left central incisor with 4½ days extraoral time. Treatment guidelines for avulsed immature permanent teeth with prolonged extraoral dry time were followed. Portland cement was used for obturation of the root canal. The clinical and radiographic findings after 18 months revealed minimal inflammatory root resorption and ankylosis of the replanted tooth, whereas clinically, the tooth was asymptomatic and maintained the aesthetics of the child, suggesting the importance of replantation, although there was prolonged extraoral dry time.

Context: Ligamentous injuries around the ankle joint are among the most common sporting injuries, especially in jumping sports (e.g., basketball, volleyball). They are not always well-managed. Associated injuries are frequently not diagnosed and the rehabilitation of ligamentous injuries is often inadequate, leading to a high rate of recurrence. Aims: The aim of this study was to find out effects of ultrasound therapy (UT), UT with taping, proprioceptive neuromuscular facilitation (PNF) training, PNF training with taping in treatment, and rehabilitation of high ankle sprain injury. Settings and Design: The experimental design used in this study was random group design. Of the total population with ligament injuries of the ankle, 50 suffering from high ankle sprain injury were randomly selected. Materials and Methods: Fifty subjects suffering from high ankle sprain injury were randomly selected and divided into five groups consisting of 10 subjects in each. Group I underwent UT, Group II underwent UT with taping, Group III underwent PNF training, Group IV underwent PNF training with taping, and Group V was considered as the control group, which was managed with RICE protocol and did not receive any specialized treatment. Statistical Analysis Used: To find out the significance of the difference among the five different treatments on a particular dependent variable, analysis of covariance (ANCOVA) was used. Results: It was concluded that combining ultrasound with taping and PNF training with taping were found to be more beneficial in the treatment and rehabilitation of high ankle sprain injury. Conclusions: It was concluded that combining ultrasound with taping and PNF training with taping were found to be more beneficial in the treatment and rehabilitation of high ankle sprain injury. The combined effect of UT, PNF training, and taping may be explored by future researchers.

Context: To evaluate the residual antimicrobial effects and surface alterations of gutta-percha disinfected with four different solutions. Materials and Methods: Eighty gutta-percha cones (ISO #40) were randomly assigned to four experimental groups; different types of disinfecting solutions were used for each, namely sodium hypochlorite (NaOCl), chlorhexidine (CHX), aloe vera, and propolis (n = 20 for each group). The cones were immersed in each solution for 5 minutes and 10 minutes; thereafter they were dried. Agar diffusion assay was performed to assess the zone of inhibition. Scanning electron microscope analysis was conducted on additional 80 disinfected cones. Statistical Analysis Used: The data was analyzed using ANOVA and Bonferroni multiple comparison test and Man–Whitney U test. Results: Statistical significance was observed among the four groups (P < 0.05). Group IV displayed no statistical significance at 5 minutes and 10 minutes exposure, whereas groups I, II, and III displayed statistical significance at both exposures. Based on the above-mentioned results, gutta-percha when immersed in propolis for 5 minutes and 10 minutes had shown better residual antibacterial action as compared to other test solutions. No surface alterations were detected on gutta-percha cones during the selected time intervals. Conclusion: Propolis followed by aloe vera possesses superior antibacterial efficacy as compared to sodium hypochlorite and chlorhexidine and does not cause any surface alterations to gutta-percha.

The development of cancer therapies depends on identifying exploitable differences between the host immune response and the tumorigenicity. These include anatomic, metabolic, cell cycle kinetics, and presumed antigenic differences between the normal tissue and tumor cells. Immunotherapy also called biologic therapy is a treatment that uses body's own immune system to fight against cancer. Cells such as dendritic cells (DCs), natural killer cells, effector T-cells, and molecules such as complement can be used in various treatment modalities which are segregated as “active” and “passive” based on their ability to engage the host immune system. Further both active and passive immunotherapies can be subdivided into specific and nonspecific approaches. Thus, it is essential to understand the therapeutic approaches and the vaccines made based on the role played by these cells and molecules to circumvent the barriers of tumor microenvironment for an antitumor response. Hence, through this article efforts were made to comprehensively explain the concepts of cancer vaccines and immunotherapies in the treatment of oral cancer.
