Different classification system for failures in tooth supported fixed partial denture: a systematic review
V Chandrakala, S Deepmala, G Srivatsa
January-March 2019, 6(1):17-20
Fixed prosthodontic treatment can offer exceptional satisfaction for both patient and dentist but failure may occur at any time right from diagnosis to treatment phase which can be frustrating. The dental literature is lacking in classification of failures in Fixed partial dentures. The cause may be that signs and symptoms of failures are varied and often complex and there is the additional problem of reaching a common interpretation among investigators on the definition of failure. When dealing with failed or failing fixed restorations, proper knowledge of diagnosis, assessment of the clinical condition and technical skills are absolutely necessary. Hence it is important to be aware of obvious and subtle indications of prosthesis failure and have a working knowledge of the procedure that are necessary to remember the situation. This review focusses on classification systems of failures associated with tooth supported fixed partial denture proposed by different authors.

Tanmay Das, Shashank Gupta, Jenny Atom, Ronel Lairenlakpam, Supriya Gupta, Aakanksha Chaudhary
July-September 2019, 6(3):66-68
The permanent teeth with open apex, blunderbuss canal, and Ellis Class IV fracture are difficult to treat as a traditional root canal procedure. Apexification is induction of apical closure, the treatment of choice for necrotic teeth with immature or resorbed root. Mineral trioxide aggregate (MTA) has been proposed as a potential material for formation of hard tissue apical barrier. Use of anatomical post results in better prognosis of the present case. This case report presents endodontic management of a fractured maxillary right central incisor with apexification and compo-post to support weak canal and to provide tooth structure. A 21-year-old male patient came to the Department of Conservative Dentistry and Endodontics, Jaipur Dental College and Hospital, Jaipur, with the chief complaint of broken upper front tooth due to accidental fall (6–7 years). Dental history of discontinued endodontic treatment 1-year back was observed. Treatment includes two phases – endodontic phase and re-construction phase followed by full-crown porcelain-fused metal prosthesis. This case report discussed an improved option of application of chairside customized made fiber posts are preferred as they stimulate the root canal anatomy, provides increased retention and adaptation and also esthetics.

April-June 2019, 6(2):46-48
The first method for rapid prototyping was introduced in the 1980s in the field of engineering for the fabrication of a solid model based on a computed file. The innovation of digital technology have revolutionized dentistry, and this digitized medical treatment. Rapid prototyping is a type of computer aided manufacturing that make physical objects from computer data. It is a technology that is capable of making physical objects directly from 3D computer data by adding a layer upon layer and 3D physical structures are known as rapid prototypes. These includes steriolithography, selective laser sintering, 3D Printers and fused deposition modeling. Rapid prototyping are used in various branches of prosthodontics like Implantology, fabrication of cowns and bridges, mold for complete dentures and in maxillofacial prosthodontics. Fabrication of prosthesis by these technologies have reduced reliance on human variables and thus have overcome the limitations of conventional method which requires considerable human intervention. RP techniques are increasingly playing an imperative role in dentistry and will become one of the mainstream technologies for digital fabrication of dental prostheses in near future.

January-March 2019, 6(1):7-10
Objective: Sex determination can be done by buccal epithelial cells in saliva traces found at a crime scene by examining the presence of Barr bodies in the nucleus of the epithelial cells. The present study aims to assess the efficacy of sex determination using Acridine Orange (AO) and Papanicolaou (PAP) stains for the detection of Barr bodies in buccal mucosal scrapings. Materials and Methods: Buccal scrapings from 120 healthy individuals (60 males and 60 females) were collected and were stained with AO and PAP stains. The analysis of fifty epithelial cells in each sample was done for the identification of Barr bodies. The presence of Barr bodies ≤ 5% in the sample was recorded as male and those with > 5% was recorded as female. Both stains were evaluated for percentage accuracy in determining sex. Results: In AO-stained slides, the percentage of Barr bodies ranged from 4 to 31 in females and from 0 to 9 in males, whereas with PAP the ranges recorded were 3–21 in females and 0–6 in males (P < 0.001). AO and PAP stains for detecting sex accurately, showed sensitivity and specificity of around 97.9% and 96.2%, respectively. Conclusion: Using Barr bodies in the buccal cells, providing up to 95%–98% accuracy, made it a considerable aid for sex determination. AO stain proved better than PAP stain for visualizing nuclear details with its remarkably shorter staining time and confirmed superior sex estimation efficiency compared to PAP stain.

January-March 2019, 6(1):14-16
Introduction: Periodontitis is a multifactorial disease, of which bacterial plaque is the main cause for the initiation and progression of periodontitis. Elimination of bacterial colonization is the main objective of periodontal therapy. Scaling and root planing (SRP) has been the main treatment modality, but inaccessibility into deep pockets can leave residual deposits in the pocket resulting in recolonization pathogenic organisms in treated areas. This led to the use of antibacterial agents as subgingival irrigants as an adjunct to SRP. Ozone is known for its antimicrobial effect. Materials and Methods: Forty sites with probing pocket depth ≥6 mm were included in the study. The test sites were subjected to ozonized water subgingival irrigation, and control sites were subjected to subgingival irrigation 0.2% chlorhexidine. The clinical parameters were recorded initially and after 1 month along with microbiologic sampling. Results: Baseline values showed no statistically significant difference in any of the clinical parameters at the test and control sites. Value of P < 0.01 is considered as statistically significant. Gingival index, probing pocket depth, and clinical attachment level showed a statistically significant reduction after 4 weeks in both test and control sites. Conclusion: Ozonized water subgingival irrigation is effective in improving oral hygiene, reducing gingival inflammation, decreasing pocket depth, and increasing attachment levels when used as an adjunct to SRP in patients with chronic periodontitis.

Prasanth Viswambharan, AR Adhershitha
October-December 2020, 7(4):91-95
Introduction: Flexural strength is one of the most important properties which determine the clinical success of dentures. Even though titanium oxide nanoparticles (nano-TiO2) and zirconium oxide nanoparticles (nano-ZrO2) are extensively used to modify the properties of polymethyl methacrylate (PMMA) resin, there is negligible documentation in the literature comparing these two. Aim: The aim of the study is to find out and compare the effect of incorporation of 1 weight % nano-TiO2 and nano-ZrO2 on the flexural strength of heat-activated PMMA resin. Materials and Methods: 1 weight % of TiO2 and ZrO2 nanoparticles were weighed using a digital weighing balance and mixed with PMMA resin powder using the geometric dilution method. Sixty “35 mm × 10 mm × 3 mm” rectangular-shaped specimens fabricated were divided into three different groups, each containing twenty samples each. The specimens were loaded to failure at a crosshead speed of 1 mm/min and with 500 N load cell in a Universal Instron Testing Machine, Model 3345. Flexural strength was registered by the machine with 0.001 MPa precision. Results: PMMA with nano-TiO2 group had the maximum flexural strength, load at maximum flexure, and load at break followed by unreinforced PMMA and PMMA with nano-ZrO2. Statistically significant difference was noted between the three groups (P < 0.001). Post hoc analysis using Tukey's post hoc test showed a statistically significant difference for all three pair-wise comparison. Conclusions: Within the limitations of this study, it can be concluded that nano-TiO2 greatly enhanced the flexural strength, load at maximum flexure load, and load at break of PMMA resin, whereas nano-ZrO2 significantly reduced these properties of PMMA.

Objective: The objective of this study is to compare and evaluate the effectiveness of maxillary canine retraction using flap and flapless corticotomy. Materials and Methods: A sample of 10 adult patients undergoing orthodontic treatment requiring therapeutic extraction of maxillary first premolars bilaterally were selected, compliant with the inclusion criteria. By random allocation, one site was selected for flap corticotomy-facilitated orthodontics (CFO) and opposite site for flapless CFO. After corticotomy procedure, maxillary canine retractions were done on both the sides using sliding mechanics. A paired t-test was used to determine the statistical significance of the difference in the amount of tooth movement between the flap and flapless sides. Results: There were statistically significant differences (P ≤ 0.01) in the rates of anteroposterior movement of the canines between the flap and flapless sides at all measurement times, and the rates of canine retraction were consistently higher in the flap side than in the flapless side. Conclusions: Flap corticotomy technique is more effective as compared to that of flapless corticotomy technique. Clinical Relevance: Flap corticotomy will be more effective clinically; however, the histologic correlation in regard to the changes in both the technique would be more beneficial.
