Background: Teacher’s training /workshop are aimed at orienting teaching staff with principles of teaching, learning and evaluations, as a part of faculty development program. However, implementation and effectiveness of such training program have not been evaluated to asses the degree of transfer of teachers’ training from teacher to the student. Therefore, a questionnaire based study was undertaken to evaluate the effectiveness of faculty development programme through its implementation in academic curriculum.
Material and Method: All the interns of Sharad Pawar Dental College, Sawangi (M), Wardha were enrolled in the study group. The students those who have not attended a single activity were excluded from the study group. Questionnaire were framed and distributed to the students. Faculty those who have undergone various health profession education training programmes were identified and data was collected from them regarding conduction of various activities.
Result: 78% of the students were in agreement with the designing of curriculum and timely display of syllabus. However, most of the students were not satisfied with the conduction of Problem based learning (PBL) and integrated teaching (ITP). 100% of the faculty was confident to design curriculum for their subject after training as compared to 9% before training. Training programme helped faculty for powerpoint presentation, conduction of PBL, OSCE and setting the question paper as per the guidelines of the University Conclusion : Our results confirm that the training package is feasible, acceptable and useful for teachers with possible reinforcement.

One of the most common challenges faced by the dental professionals is resorbed alveolar ridges which can be in horizontal and vertical dimension . Alveolar distraction osteogenesis is one of the mode of treatment for improving the deficient areas of alveolar ridges.
Alveolar distraction osteogenesis is biological process which involves progressive incremental traction between the vascularized bone segments in order to gain new bone formation. Osteotomy is usually performed which is followed by placing a osteo-distractor device which controls the separation process. By using this technique, the use of bone graft can be avoided as it produce same character and morphology of bone. It results into growth of the soft tissue with development of new bone on deficient ridge. As bone height is restored by this technique ,it is feasible to place longer dental implants. 
This review discuss about ride augmentation and various procedure which are performed to restore resorbed alveolar ridge. It emphasize on importance of alveolar distraction osteogenesis with some history of the technique on the basis of evidences available.
To conclude, distraction osteogenesis is an efficient method to restore the alveolar ridge height for better adaptability of dental implants.

The concept of nanocoatings was given by Chai et al., 1995 so as to enhance the mechanical as well as biological properties of Hap (hydroxapetite). This material does not have ideal mechanical properties and due to its bulk porosity, HAp can’t be used to take up load, and is therefore used for coating for utilizing its ductility of the substrate level. One can increase the mechanical properties of HAp by forming HAp nanocoatings. It can be achieved when HAp is united with other nanoscale based materials as secondary phase. Thin films of polymer(biodegradable) with gentamicin have been mixed to function as ‘composite coatings’ for metallic implants as well as devices which fix fractures to keep away from infections associated with implants. Calcium phosphate can imitate structure as well as composition of bone mineral called normal hydroxyapatite (HAp). Thus, it becomes a perfect alternative when thinking of an appropriate biomaterial in order to replace and imitate bone such as in case of an implant. Calcium phosphate has a special consideration on its introduction in the dental fields as it is chemically similar to bone of a human being, especially in terms of its characteristics of dissolution which enables the growth as well as regeneration in bones. Calcium phosphate nanocomposite coatings are merged with other materials which are micro or nanosized which increases its mechanical properties. Development of a newer generation of nanocomposite coating is recently being known which have nanomaterials like bioglass, carbon nanotubes as well as collagen to enhance ‘osseointegration’. The initiative of nanocoatings and nanocomposites is to develop the biological and mechanical properties of calcium phosphate and alter properties related to surface of implants which are used in dentistry to speed up the process of healing and thus nanocoatings are being introduced in dentistry

Background: An endodontic treatment aims to recover and maintain dental elements, which have pulpal or endodontic periapical pathology, thus eliminating the microorganisms to ensure an acceptable apical seal. Objectives: The three different conditions using naked vision, loupes and Dental operating Microscope were compared here to test the sealing ability of biodentine using glucose penetration method. Methods: Ninty mandibular bicuspids were selected that were further divided into three groups (n=30) for which canal were prepared using F2 ProTaper Universal (Dentsply Maillefer, Switzerland) and a retrograde cavity is prepared in each of the extracted single rooted tooth using proultra surgical tip (Dentsply, USA) 3mm short of apex . Cavity was then filled with biodentine condensed against plugger placed inside the canal. All the procedure were confirmed under unaided vision/ naked vision, under dental loupes (IDS Denmed 3.3X). and under Dental operating Microscope (Carl zeiss 12.5X) for each group. All the samples were then analyzed with a spectrophotometer at a suitable wavelength. The (ANOVA) test of comparison was analysed for multiple groups preceded by the post hoc pair-wise comparison test. Results: The filling of biodentine is observed under dental operating microscope that showed better sealing properties when compared to the unaided vision and dental loupes, thus proving statistically significant. The glucose leakage evaluated under working conditions namely unaided vision, dental loupes and Dental operating Microscope were 0.236, 0.111 and 0.055 respectively. Conclusion: The restoration done under Dental operating Microscope showed superior sealing properties when compared to the other working conditions respectively.
