The retrieval of a surgical blade broken within the alveolar bone during minimally traumatic tooth extraction
Minimally traumatic tooth removal is the norm for removing teeth when a dental implant is planned at that site. The quantity of available bone is the primary requisite to place an implant. The initial use of a scalpel blade to widen the periodontal space followed by the use of luxators is one of the techniques that is being followed for atraumatic extraction. A case of accidental breakage of a number 11 scalpel blade while attempting tooth removal and the method adopted in removing this portion of the blade without further bone destruction is reported here. The authors have not found any previously published cases, reporting the breakage of a scalpel blade during the bone expansion procedure and its management.

“A Comparative Evaluation of Microbial Adhesion of Oral Pathogens to Three Different Types of Post system: An Invitro Study”
Objective: This study evaluated the adhesion probability of three common microflora present in the oral cavity as Staphylococcus aureus, Streptococcus mutans and Candida albicans to the three frequently used post systems: Stainless Steel metallic post, non-metallic Composite Fiber post and Quartz Fiber post. Materials and Methods: To compare the adhesion rate, fifteen posts; five of each material type were tested after impregnating them in salivary substitute for 1 hour, and each post type was cultured with the three different pathogens separately using BHI and sucrose broth respectively at 37°C incubation for 4 weeks. Miles and Mishra standard methodology were followed to form microbial biofilms and results were analyzed by counting of colony-forming units (CFUs/mL). Results: The highest probability of bacterial adhesion for Staphylococcus aureus followed by Candida albicans was seen with quartz fiber post. However, the adherence ratio when evaluated statistically was not significant with P-value > 0.05. The evaluation of mean values of each indicates a slightly increased adhesion of Staphylococcus aureus (1.94 x 104) and Candida albicans (12.10 x 106) to quartz post. In case of Stainless steel, the mean values of S. aureus (1.05 x 104) showed a slight decrease in adhesion when compared to composite fiber post (1.21 x 104). Candida albicans population adhered more to stainless steel (6.63 x 106) when compared to composite fiber post. Conclusion: In this pilot study, maximum growth of microorganisms to quartz fiber post material was observed, although a further large sample size is required to corroborate the findings. If confirmed, with larger data sample, the quartz fiber post can be avoided in cases of periapical inflammation and retreatment cases requiring posts.

More to explore; the mesenchymal stem cells (MSCs) major tissue sources, known surface markers, and its immunomodulation properties.
Mesenchymal stem cells (MSCs) are currently available for a range of applications and have become a good material for regenerative medicine, tissue engineering, and disease therapy. MSCs are self-renewing, multipotent progenitor cells with multilineage potential to differentiate into cell types of mesodermal origin, such as adipocytes, osteocytes, and chondrocytes, and exert potent immunosuppressive potentials. In the present review, we highlight the currently reported variations in the differentiation potential of MSCs from different tissue sources, the minimal criteria to define MSCs from various tissue environments, and provide a detailed description of MSCs surface markers. Furthermore, MSC's immunomodulatory features secrete cytokines and immune receptors which regulate the microenvironment in the host tissue also revisits in detail. We propose that there are likely more sources of MSCs waiting to be discovered. We need to Standardize MSCs characterization by selecting markers for isolation, cellular and molecular mechanisms involved in MSC-mediated immune modulation, and other functionalities of MSCs should be characterized prior to use in clinical applications.

Analysis of the stress distribution Pattern of anatomic and nonanatomic tooth forms on maxillary and mandibular edentulous ridges- A Photoelastic study”
Aim: To compare the type of stress distribution pattern occurring with anatomic and non-anatomic tooth forms beneath a complete denture in both maxillary and mandibular arch. Methodology: A photoelastic model of the edentulous maxillary and mandibular ridge was prepared meticulously to simulate the human mandible and maxilla. Two sets of acrylic teeth with anatomic and non-anatomic occlusal forms were used to fabricate upper and lower dentures. A vertical static load of 100 N was applied through the mandibular model to the maxillary model. After load application on the dentures the photoelastic model as well as the upper and lower complete dentures were sectioned in the midline. The sectioned photoelastic model was viewed through a polariscope to observe the fringe pattern indicating varying amounts of stress distribution. In this study, a two-dimensional photoelastic stress analysis technique was utilized. Results: Force per unit area was observed more in anatomic teeth than the non-anatomic counterpart. Hence anatomic tooth forms may increase the possibility of bone resorption rate over a period of time. However, in non-anatomic lower teeth, a decrease in value was observed from posterior to anterior region. Conclusion: Stress of greater magnitude was observed with cuspal teeth whereas non-anatomic (0°) showed slightly less magnitude of stress. Depending upon the clinical situation the clinician needs to choose the type of occlusal tooth forms for edentulous patients

Bacterial Inv Dentinal Tubules from the External Root Surface with and without an Intact Cemental Layer Confocal Laser Scanning Microscopic Study
Aim: To evaluate the invasion of two bacterial species; Streptococcus sanguinis (S.s) and Aggregatibacter actinomycetemcomitans (A.a) in radicular dentinal tubules with and without an intact cemental layer using confocal laser scanning microscopy. Methodology: 10 intact freshly extracted human teeth were prepared and divided into 2 groups, Group 1: S.s (1a: S.s without cementum, 1b: S.s with intact cementum) and Group 2:A.a (2a:A.a without cementum, 2b: with intact cementum). The cemental layer on each root was removed from one side and kept intact on the other side. The specimens were incubated in the bacterial suspension for 15days at 37˚C. The specimens were sectioned, mounted, stained with a fluorescent dye and viewed under the Confocal Scanning Electron Microscope at 40X magnification. The penetration of bacteria and presence of live bacteria in dentinal tubules in all the groups was analyzed. Results: In both the groups there was a significantly higher penetration of bacteria through the exposed dentin as compared to sections with intact cementum. However, there was a significantly higher penetration of Streptococcus sanguinis as compared to Aggregatibacter actinomycetemcomitans. Conclusion: An intact cemental layer protects the dentin from invasion of bacterial species. These bacteria can lead to reinfection of treated periodontal pockets, pulpal inflammation or persistence of periapical infections. Therefore, management of endodontic-periodontic lesions and periodontal therapies should aim at preserving or regenerating a healthy cemental layer.

Evaluation of Speech Intelligibility of a Cleft Palate Patient with Speech Prosthesis before and after Palatographical Analysis and Prosthesis Modification
Abstract The aim of the study was to evaluate the alterations in speech intelligibility in a cleft palate patient, before and after extending and modifying the palatal contour of the existing prosthesis using a correctable wax recording. An eight-year-old girl studying in second grade with a velopharyngeal defect using an obturator reported to the outpatient clinic complaining of lack in clarity of speech. The existing prosthesis was lacking a speech bulb hence it was decided to add the speech bulb to the existing prosthesis and evaluate the speech. Even after the use of speech bulb it was observed that she was unable to pronounce the vowels and words like shoe, vision, cheer, etc. clearly. Hence, a palatography was done using a correctable wax technique and the existing prosthesis was altered accordingly. Great improvement in speech, mastication, and velopharyngeal function was achieved after the palatography alteration of the existing prosthesis.

A Custom Made Implant Supported Auricular Prosthesis Designed by Rapid Prototyping for Compromised Bone Support: A Case Report
Implant supported auricular prosthesis requires a minimum of 6mm bone depth in the temporal bone area behind external auditory meatus. Extra oral implants are available from 4mm to 7mm length with 5 to 6mm diameter flange. When the bone height is compromised and when only few regions have favorable positions which are not part of the slot area all the existing extra oral systems cannot be used. In cases with compromised bone condition, a custom made implant is the best choice that can offer good prognosis.

The Current Status of Stem Cell Regeneration in Intra Oral Applications—A Systematic Review
Abstract Aim: 1) To review the literature of various applications of stem cell regeneration in dentistry from 2010 to 2016. 2) To review these studies and to summarize the current status of stem cell regeneration in intra oral applications. 3) To present the available successful data with regard to stem cell regeneration in dentistry and to highlight the future trends. Materials and Methods: Search Protocol: A systematic search was made in the PubMed database with the key words gingiva, papillary reconstruction, periodontal ligament, dental pulp, salivary gland, enamel re-mineralization, dentin, cementum, bone, whole tooth, cleft palate, regeneration and stem cells. All articles from 2010 to 2016, relevant to the topic were included. After the search a total of 1826 articles were obtained which were screened and categorized by three independent reviewers as review papers, in vitro, animal and human studies, pertaining to stem cell regeneration in intra oral applications. On the basis of the extracted data and outcome measures, conclusions were drawn. Results: Maximum number of animal studies has been done to regenerate periodontal tissues, bone, dentin and pulp tissues. Few human studies have been done till date. Although clinically, researchers have been able to regenerate periodontal-like tissue, bone and pulp-like tissue, they still haven’t been able to regenerate tissues that completely resemble tissues in their natural form. Conclusion: The future of stem cell therapy in dental applications looks promising. The predictability and efficacy of outcomes, as well as safety concerns of stem cell therapy is yet to be fully established. Ongoing research and development of newer scaffolds, understanding various signaling molecules and their cues, understanding gene expression and proteomics of stem cells are the future directions that will take us a step forward to achieving successful regeneration.

Coronal disassembly systems and techniques: An overview.
To create a general awareness among the clinicians regarding the appropriate choice of crown removal systems and techniques in various clinical situations. Fixed prosthodontic treatment is often faced with complications involving failure of restoration or of the abutment due to improper treatment planning. In such situations, further management can be accomplished either by removal and replacement or repair of the restoration. Removal of the crown and bridges for refabrication is extremely tedious and can lead to unpredictable consequences if proper technique is not used. An external device is always required for the removal of the failed restorations. Decrowning devices are a boon to dentistry to deal with such situations. Numerous decrowning devices are available commercially. This review describes and demonstrates the various available devices based on the mode of action. Literature search was carried out using PubMed and Google Scholar from 1970's to till date. Any decrowning device will be successful only if used appropriately. Hence, this literature attempts to suggest the possible application of each system based on clinical situations. A few modified techniques have also been discussed in this article for ease of the clinician.

Implant Retained Auricular Prosthesis with a Modified Hader Bar: A Case Report
Auricular prostheses for defects of external ear are retained either by mechanical means or implants. All implant retained prostheses are retained by various means such as bar and clip, magnetic attachments or a combination of bar, clip and magnets. The commonest problem encountered with the bar and clip system is loosening of the clip after 3–4 months. When magnets are used as retaining component they tend to corrode over a period of time. So various alternative retention methods which possess good retentive qualities, ease of reparability and patient friendly were tried. In the present case a newly modified Hader bar design which can act as an additional retentive feature apart from the clip is employed to increase retention. The major advantages in the modified Hader bar system were that only two implants were employed, the additional loops in the Hader bar prevented micro movements and the retentive acrylic locks were easy to repair if broken. The modified Hader bar has anti-rotational slots which prevents the sliding or rotation of the prosthesis which gave new confidence to the patient who was otherwise worried of inadvertent displacement of the ear prosthesis while playing.

In Vitro Comparative Evaluation of the Physical and Mechanical Properties of Two Soft-liners Coated with Different Types of Coatings.
ABSTRACT Aim: To evaluate the changes on the physical and mechanical properties of acrylic and silicone based soft liners after applying four different types of coatings. Methods: A total of 50 samples were prepared and divided into two major groups viz. Group A-Exact-On (30 samples) and Molloplast-B (30 samples). Group A and B were further subdivided into 5 subgroups l,ll, lll, lV and V containing 6 specimens each. The samples were coated with four different types of coatings and were compared to the uncoated control group (subgroup). Main composition of two types of Monopoly were chemically activated methylmethacrylate monomer, clear methylmethacrylate polymer, heat activated methylmethacrylate monomer. Two new types of coatings were made with n-butyl cyanoacrylate.These two coatings were never tried before in any literature review.The coated samples were tested for Hardness, Permanent deformation, Tensile strength, Water absorption determination and the coated surfaces were observed under SEM and compared with the uncoated control group. Results: Molloplast-B, a silicone based had longer shelf life but a coated acrylic based liner was seen to be equally good. Cyanoacrylate monomer coating and self cure monopoly coating were superior to other coatings. All results were statistically analyzed by 2-way ANOVA. The mean values for hardness ranged from 24.t6 to 29.33 Shore A for Group A and 41.50 to 42 Shore A for Group B. Values of permanent deformation ranged from 1.01 to 0.93%for the Exact-On (Group A) and 0.158 to 0.140 % in coated Molloplast-B samples (Group B). Mean values of Tensile strength ranged from 5kg/cm2 to 6.00kg/cm2 in Group A and i.6.33 kg/cm2 to t7.67kg/cm2 in Group B. It was observed that among the coatings Cyanoacrylate Monopoly coating was more efficient in preventing water absorption and leaching followed by Cyanoacrylate Monomer coating. Conclusion: None of the coatings affected the physical properties of tissue conditioners. All coatings prevented water absorption from tissue conditioner and prolonged the life of tissue conditioner.

Effect of fabrication process on the bond strength between silicone elastomer and acrylic resin for maxillofacial prosthesis.
Abstract This study evaluated the effects of the fabrication process on tensile bond strength between maxillofacial silicone elastomer and acrylic resin. A common maxillofacial silicone elastomer (VST-50), two primers (Sofreliner primer and R-SI-LINE Plasticbond), and two acrylic resins (Unifast III and Palapress Vario) were selected. Silicone elastomer between primed acrylic resin plates were polymerized using a metal flask mold or a flaskless stone mold. Bond strength of the specimens was measured by a tensile test and analyzed using two-way analysis of variance (ANOVA) with Tukey's honest significant difference test. All fracture surfaces showed interfacial fracture. Both the fabrication process and the primer-acrylic resin combination affected bond strength, and two-way ANOVA indicated a significant interaction. Bond strength was generally greater when silicone elastomer was polymerized using a flaskless stone mold. Similar articles
