Positively charged polyvinylidene fluoride (PVDF) membrane: A potential alternative for absorbent paper points in endodontics
No full textAim The purpose of the study was to evaluate the performance of Polyvinylidene Fluoride (PVDF) as an alternative to paper points (PPs) for endodontic treatments. Methodology The paper points and the PVDF membrane were evaluated for endotoxin binding using Limulus Amebocyte Lysate (LAL) assay. New paper points and the PVDF membrane were evaluated for the presence of endotoxins. Results Absorbency and endotoxin removal with the 0.22µm PVDF membrane was significantly greater than any of the paper points tested. There was significantly more endotoxin found in new paper points compared to the PVDF membrane. Conclusion In conclusion, our study showed that the 0.22μm PVDF membrane was significantly more absorbent and removed more endotoxins than PPs
Role of PEEK in RPD: A systematic review
No full textAim This systematic review aims to analyse and appraise the literature concerning PEEK dental prostheses critically. Methodology The following focused question was constructed ‘Are dental prostheses made of PEEK inferior to those made of other materials in terms of clinical- and patient-reported outcomes?’. The CONSORT (Consolidated Standards of Reporting Trials) tool was used for the quality assessment of the randomised clinical trials. Results A total of 12 studies were included in this review. Two case studies received an overall grade of medium and the overall quality of six studies was graded as ‘low’. All three observational studies and the only randomised controlled trial received scores of ‘medium’. Conclusion PEEK-based dental prostheses may provide a viable and more esthetic alternative to conventional prosthodontic appliances. However, within the limitations of this study is the evidence to ascertain the long-term viability of PEEK-based dental prostheses. Future studies should focus on conducting large-scale, multicenter trials to compare the survival rate of PEEK prostheses to that of conventionally available prosthodontic appliances
Evaluation of preference for posterior missing teeth rehabilitation in practising prosthodontist: An original research
No full textAim: The purpose of the present study was to assess various treatment options amongst prosthodontists for rehabilitation of missing posterior teeth in their patients. Methodology: 100 prosthodontists participated in this questionnaire survey. 7 questions were asked from the practicing prosthodontists about various treatment options they choose for rehabilitation of posterior missing teeth. They were also asked about how patient’s choices as well excess cost of materials, influence their decision as well as long term stability. Statistical analysis like- standard deviation, mean etc. p value <0.05 was considered significant. Results: We observed that 69% of prosthodontists (1.38±0.92) believed that missing posterior teeth rehabilitation does indeed suffer from more number of failures as compared to anterior teeth replacement due to maximum masticatory load put on the posterior teeth (p=0.03). Patient preference influences the decision making of almost 76.9 % prosthodontists especially based on compliance, cost as well as phobia. Cost is always an important decision maker for 89% participants while selecting the treatment option (p=0.0145). Conclusion: Fixed dental prosthesis has become the treatment of choice for long term stability according to the prosthodontists. However, cost effective removable partial dentures will always be there for elder population
Choice of grafting options post apicectomy procedure by specialist endodontist: An original research
No full textAim: The purpose of the present study was to evaluate the choice of grafting options post apicectomy procedure by various endodontists. Methodology: In the present descriptive survey, 8 questions were asked from 50 Endodontists, regarding the treatment options in cases of periapical pathologies as well as graft material preference after the apicoectomy procedure was performed. They were asked for usability, economics, long term healing of periapical region related with post apicoectomy graft placement. Results: 49.5% of participants preferred calcium hydroxyapatite as a graft material as compared to bone granules or PRP. It was also noted that radiographic resolution and improved trabecular pattern in peri-radicular area was the most important aspect that endodontists look into while looking at healing of periapical lesion (1.43 ±1.002). Most stable graft according to 61% of participants were autologous transplants- bone granules as well as calcium hydroxyapatite (1.422±1.02). Conclusion: Endodontists preferred calcium hydroxyapatite or bone grafts, which has more stable long-term results
Comparison of laser and cautery in maxillofacial surgical procedures: An original research
No full textAim: The purpose of the present study was to evaluate the comparison of laser versus cautery usage in various maxillofacial surgical procedures. Methodology: In this randomized double-blind clinical trial, 40 individuals were randomly allocated to two groups: group 1 (G1) consisted of 20 individuals assigned to treatment with diode laser and group 2 (G2) consisted of 20 individuals assigned to treatment with electrocautery. The following transoperative parameters were evaluated: bleeding, temperature, and surgical technique parameters (energy deposited on tissue, flow rate, and time of incision). The postoperative parameters evaluated were as follows: pain, functional alterations (chewing, speaking), analgesic medication intake, swelling, healing of the wound area, and patient satisfaction. Results: Among the 40 individuals included in the study, four (two in G1 and two in G2) did not complete the entire follow-up. Therefore, 36 individuals (18 in G1 and 18 in G2) participated. Participants in G1 and in G2 had similar demographic characteristics. No difference regarding the trans- or postoperative parameters evaluated was observed between G1 and G2 (p > 0.05). Also, no difference regarding the time for healing was observed between groups. Conclusion: Diode laser seems to be as effective and safe as electrocautery when applied under similar conditions
Comparison of different plating systems in bilateral para symphysis fractures: An original research
No full textAim: The purpose of the present research was to evaluate the comparison of various plating systems used in treatment of bilateral para-symphysis fracture. Methodology: Fractures were generated in 3-dimensional finite element models, and were fixed with a single miniplate, parallel double miniplates, or perpendicular double miniplates. A 300 N perpendicular load was then applied on the left molar region, and a finite element analysis was performed. Vertical gaps between the fractured surfaces of bilateral para-symphyseal areas, maximum stress within the screw/plating system, and maximum stress around screw holes in the bone. Results: Compared to the single miniplate, both the parallel and perpendicular double miniplates demonstrated significantly less stress in the screw/plating system and screw holes in the bone. In addition, the perpendicular double miniplates had significantly smaller vertical gaps between fracture surfaces when compared to the single miniplate. Comparing parallel and perpendicular double miniplate fixations, less stress was found around the screw holes of the perpendicular miniplate models than those of the parallel miniplate models. There were no differences in vertical gaps or maximum stress within the screw/plating systems between the 2 double miniplate fixations. 
Knowledge about different rehabilitation options in geriatric population: An original research
No full textAim: The purpose of the present research was to evaluate the need for rehabilitation and various options for consideration amongst the geriatric population. Methodology: One hundred and three geriatric subjects aged between 65 to 90 years were enrolled. The data were collected using a structured questionnaire designed to obtain information regarding home care and geriatric rehabilitation care. Results: Sixty (58.2%) were females and 43 (41.7%) were males. The majority were <80 years of age, 82 (79.6%). Around 52 (50.5%) subjects knew about rehabilitation care and most believed that geriatric rehabilitation care is beneficial. Sixty-four (62.1%) subjects were involved in socialization once a week, 29 (28.2%) once in a month, 6 (5.8%) biannually and 4 (3.9%) marked not at all. Among all, 41% reported being isolated, and 86% were getting enough psychiatric/physical care at home. Conclusion: Although 52 (50.5%) of the study subjects reported knowing geriatric rehabilitation care due to limited education as well as lack of access led to more neglect of the elderly. There is a need to design and conduct rehabilitation programs to control morbidity and improve the quality of the geriatric population
Isolation systems and its effectiveness in oral and maxillofacial surgery: A systematic review
No full textIntroduction: The success of restoration processes depends on the efficient control of moisture and microorganisms. Dental restorative procedures frequently use rubber dams as an isolation technique. There is still room for evidence-based discussion over how rubber dam use affects the durability and caliber of dental restorations. In this review, the effects of rubber dam isolation vs alternative isolation techniques for dental restorative procedures are compared. Materials and Procedures: An extensive online search in the various databanks of the EMBASE, Medline, Pubmed, and Scopus was conducted. The keywords searched were “isolation, oral surgery, dental surgery, retractors, rubber dam, and methods of isolation.” The studies selected were longitudinal research design and randomized trials. To ascertain the risk of bias, meta-analysis was carried out. The outcome was measured as the successful restoration at the end of follow-up period representing the thorough isolation. Results: A total of 1342 people were involved in six studies from across the world that were carried out between 2010 and 2015. High bias risk existed in all the studies. Five investigations compared the rubber dam vs cotton rolls. Due to discrepancies in the data supplied, one study was omitted from the analysis. Three of the four trials that were still running showed restored survival rates with all having a follow-up of at least six months. The survival of the restored composite teeth for six months in rubber dam isolation with odds ratio of 2.29, 1.38, and 1.00 at the end of six months, one year and one and half year respectively. However, the evidence was very low and speculative. The isolation was seen effective in the primary teeth specifically for the proximal lesions. None of the included studies discussed side effects or provided information on the treatment's upfront costs. Conclusion: The application of rubber dams in dental techniques may result in successful outcome compared to cotton rolls, according to some low-certainty evidence revealed in this research. Other times, the evidence is really ambiguous. It is necessary to conduct additional, high-quality studies investigating how rubber dam use affects various restorative procedures
Comparison analysis of poly ether ketone and poly methyl metha acrylate used in prosthodontia for dentures: Original research
No full textIntroduction- Several materials have been introduced in dentistry for dentures for over last century. Poly Ether Ether Ketone (PEEK) has adequate flexural strength as a denture base and thereby prolonging its clinical longevity and also overcoming the most common reason for failure of Poly Methyl Metha Acrylate (PMMA) denture base that frequently results in the fracture. Aim- The aim and objective of the present study is to evaluate and compare the flexural strength and hardness of heat-cured PMMA denture base with PEEK. Material and methods- The sample size comprised of 60 samples of PMMA and PEEK which were prepared and divided into two groups i.e.; group I and group II respectively, of 30 each. Both the groups were further divided into subgroups consisting of 15 samples of PMMA and PEEK. The flexural strength was test in group I specimens by universal testing machine (UTM), and group II samples was subjected to hardness test using Vickers microhardness tester. The values were analysed statistically. The unpaired t-test was done for comparison of flexural strength and hardness of PEEK and PMMA.Result-The flexural strength of PEEK was 185 MPa, while that of PMMA was 85 MPa
Evaluation of choice of medicine for hair growth in practising hair implant surgeons- original research
No full textAim The purpose of the present research was to assess the treatment effects of various pharmaceutical agents used by hair implant surgeons to induce hair growth in affected patients. Methodology this study, 500 patients we combined the use of antioxidants, iron, calcium, zinc, amino acids, and vitamins E, D, and C with minoxidil and finasteride to control hair loss, reverse miniaturization, and achieve new hair growth within 2-4 months with group I and II having male participants subjected to cyclic regimen and only minoxidil as well finasteride respectively whereas group II and IV had female participants also following cyclic as well as control regimen respectively. The patients were also followed clinically for 2 years and were observed to maintain their improvement. Results In Group I, the average improvement in density with cyclical medicine was 30% at 2 months and 52% at 4 months. The average improvement in caliber was 37% at 2 months and 47% at 4 months. In control Group II, density improved by an average of 2% at 2 months and 3.6% at 4 months. Caliber was unchanged in 44% of the patients.
