DOI:10.4103/jispcd.JISPCD_521_16  PMID:28316952
Aims and Objectives: Nowadays, the material that offers the best sealing characteristic in the field of endodontic treatment is the mineral trioxide aggregate (MTA), nevertheless, this material necessities an adhesive bonding agent to perfectly join to the dental surface. The aim of this study was to analyze using a scanning electron microscope (SEM) the possible microgap between the adhesive, MTA, and the dental surface. Material and Methods: Fourteen extracted molars were divided into two groups – group A was prepared with MTA-component adhesive and group B was prepared with MTA and composite dual etching. The observations were carried out with a SEM Phenom G2 Pro mode S.E.I. JMP® software was used for statistical analysis, and a t-test was used for evaluating the difference between the two groups. Results: The gap of the areas at higher magnification (1000×) with a size greater than 5 microns in width and 20 microns in length were considered significant, and only group A recorded significant data. Conclusions: The SEM analysis performed in the group A with interposition of adhesive and flow between the dental pulp chamber and MTA demonstrates the presence of a marginal gap of considerable amplitude in the all of the samples investigated.

January-February 2017, 7(1):15-21
DOI:10.4103/jispcd.JISPCD_359_16  PMID:28316944
Human amniotic membrane (HAM) is derived from the fetal membranes which consist of the inner amniotic membrane made of single layer of amnion cells fixed to collagen-rich mesenchyme attached to chorion. HAM has low immunogenicity, anti-inflammatory properties and their cells can be isolated without the sacrifice of human embryos. Amniotic membrane has biological properties which are important for the experimental and clinical applications in managing patients of various medical specialties. Abundant, natural and wonderful biomembrane not only protects the foetus but also has various clinical applications in the field of dermatology, ophthalmology, ENT surgery, orthopedics and dental surgery. As it is discarded post-partum it may be useful for regenerative medicine and cell therapy to treat damaged or diseased tissues.

DOI:10.4103/jispcd.JISPCD_30_17  PMID:28316951
Objectives: To compare oral health knowledge, attitude, and practices among dental and medical students in a Health care centre at Bhubaneswar, Odisha, India. Materials and Methods: One hundred and fifty BDS and MBBS students each from Kalinga Institute of Dental Sciences and Kalinga Institute of Medical Sciences of KIIT University, Bhubaneswar respectively, were invited to participate in this survey using a self-administered structured questionnaire in English comprising 27 questions, which was designed to evaluate the oral health knowledge, attitude, and practices. The obtained data was analyzed using the Statistical Package for the Social Sciences version 20 software. Results: On comparison of the scores of knowledge, attitude, and practice, the mean knowledge score was significantly higher among dental students than medical students. The study also showed that female students (both dental and medical) had better oral health knowledge and showed better oral health practices than male students. Karl Pearson's correlation coefficient test showed that, although dental students had better knowledge and attitude towards oral health, there was a lack of adequate practice among them. Conclusion: Further emphasis on oral health is necessary in undergraduate training to improve oral health knowledge, attitude, and practice among dental and medical students as they will act as role models for oral health education among individuals and community at large.

Evaluation of the role of probiotics in endodontic treatment: A preliminary study
Aarti Bohora, Sharad Kokate
January-February 2017, 7(1):46-51
DOI:10.4103/2231-0762.200710  PMID:28316949
Aims and Objectives: The principal goal of endodontics is the prevention of periapical infection. Acute and chronic apical periodontitis occur due to the persistence of pathogenic microorganisms such as Enterococcus faecalis and Candida albicans harboring the root canal systems of the teeth. The concept of the use of probiotics in addressing endodontic disease is new and has not been studied adequately. On the basis of the success of probiotics in periodontal treatment, this preliminary work was performed (a) to evaluate the antibacterial efficacy of probiotics against common endodontic pathogens, i.e. E. faecalis and C. albicans, and (b) to evaluate the potential use of probiotic therapy as an additive in endodontic treatment procedures. Materials and Methods: Two commercial probiotics were selected and evaluated based upon the numbers and concentration of organisms. Pathogenic test organisms were C. albicans (ATCC 10231) and E. faecalis (ATCC 29212). Phase 1 of the study was conducted by agar cup method test to evaluate the antibacterial activity of the selected probiotics against E. faecalis and C. albicans by measuring zones of inhibition (ZOI) in mm. Microorganisms from probiotic samples were isolated following manufacturer's instructions. Pathogenic organisms were set to a 0.1 McFarland standard challenge. Circular wells of 8 mm diameter were punched in each of the poured plates. Appropriately diluted test samples were added to the above-punched wells. The volume of the solution added to each well was 100 μl. The plates were incubated in an upright position at 37°C for 24 hours under aerobic conditions. Post incubation, ZOI was measured (mm). Phase 2 was conducted by mixing 9 ml of 30% poloxamer 407 and de Man, Rogosa and Sharpe (MRS) broth in a test tube with 500 μl of either E. faecalis or C. albicans set at an optical density (OD) of 0.252, together with 500 μl of test probiotic strain, set at a respective OD. Samples were then incubated at 37°C for 48 hours, followed by serial dilutions by 1 ml till 108. This was done to calculate colony forming units (CFU)/ml counts. Controls used were endodontic pathogens in 30% poloxamer with MRS broth without any probiotic group. Results: Probiotic groups showed inhibitory activity against E. faecalis by the agar cup method, whereas there was no effect on C. albicans. In the biofilm stage, both the test groups had an antibacterial effect on pathogenic organisms. Conclusion: This study suggests that probiotic organisms of the species Lactobacillus and Bifidobacterium are effective for preventing the growth of E. faecalis and C. albicans in vitro. Because probiotics are available in varied compositions and concentrations, further evaluation for their role in treating endodontic infection is suggested and warranted. In addition, the study suggested that poloxamer 407 could be utilized as an ideal delivery vehicle for probiotics for use as a potential endodontic intracanal medicament.

January-February 2017, 7(1):8-14
DOI:10.4103/jispcd.JISPCD_231_16  PMID:28316943
Aims and Objectives: Transmigration is a rare phenomenon seen almost exclusively in the mandibular canines. The aim of the present study is to review transmigration phenomenon. Materials and Methods: Appropriate guidelines for a systematic review were followed. The time period selected for the present systematic review was 2001–2016.The studies were selected from various electronic databases on the basis of their title, study, design, keywords, and abstracts. A total of 150 citations were searched initially, and after proper screening, 59 relevant articles were included. Additional data was obtained by searching journals and reference lists. Results: The literature search shows that transmigration is more frequent in the mandible than maxilla. The etiology of the condition is obscure; however, multiple factors have been attributed to the condition. They are more readily recognized now with the advent of panoramic radiographs. Transmigration is a rare anomaly causing varied manifestations and requires an interdisciplinary approach for management. Conclusion: Early diagnosis of impacted canines is mandatory for timely treatment to ensure facial harmony and improved function.

Piezosurgery: A boon for modern periodontics
Mathai Thomas, Uttam Akula, Kranti K. R Ealla, Nirosha Gajjada
January-February 2017, 7(1):1-7
DOI:10.4103/2231-0762.200709  PMID:28316942
Dentistry has undergone significant advancement and has seen several changing concepts over a decade. One such novel innovation is piezosurgery. Piezoelectric bone surgery or otherwise known as piezosurgery is a novel technique invented by Professor Vercellotti in 1988 to overcome the limitations of traditional instrumentation in oral bone surgery by modifying and improving conventional ultrasound technology. It is a promising, meticulous, and soft tissue sparing system for bone cutting based on low frequency ultrasonic microvibrations. The absence of macrovibration makes the instrument more manageable and allows greater intraoperative control with a significant increase in cutting safety in the more difficult anatomical cutting zone. The present review compares piezosurgery with the traditional tools and emphasizes on its mechanism of action, instruments, biologic effects, advantages, and limitations, as well as its various applications in the field of dentistry.

Sara M El Khateeb, Osama Abu-Hammad, Hani Fadel, Najla Dar-Odeh
January-February 2017, 7(1):22-27
DOI:10.4103/2231-0762.200707  PMID:28316945
Aims and Objectives: To determine the prevalence and types of jaw pathologic findings as detected in panoramic radiographs of a sample of young women attending a teaching hospital in Al Madinah Al Munawarah, Saudi Arabia, and to determine the most important factors that predict the occurrence of jaw pathologic findings. Materials and Methods: The electronic clinical files of a representative sample of female patients who attended the outpatient dental clinics were retrieved. Patients were aged 18 to 25 years. Types of pathologic radiographic jaw findings and their prevalence were determined through screening of panoramic radiographs. Data were analyzed using the statistical analysis software [SPSS version 21 (IBM Corp.)]. Multiple linear regression was used to explore the significance of some types of dental lesions as predictor variables for the occurrence of jaw pathologic findings. Results: A total of 190 patients (mean age, 22.4 ± 2.46 years) were included in the study. Periapical lesions, retained roots, and alveolar bone loss were detected in 53.6%, 24.8%, and 17.4% of the participants, respectively. Other odontogenic abnormalities such as supernumerary and impacted teeth (6.4% and 33.7%, respectively) were also detected. Patients' age was found to be a good predictor for alveolar bone loss and number of periapical lesions (P ≤ 0.05). Conclusions: A high prevalence of periapical lesions, retained roots, and alveolar bone loss was found among a sample of young female dental attendees, as shown by their panoramic radiographs. Further studies are needed to explore potential risk factors for such a noticeable trend of poor oral health, and the needed strategies to counteract this trend.

January-February 2017, 7(1):34-40
DOI:10.4103/2231-0762.200706  PMID:28316947
Aim: This work evaluated the mechanical and surface behavior of different die materials. The studied materials are polyurethane resin Exakto-Form (Bredent), Gypsum type IV, Fuji Rock EP (Gc), and Durone (Dentsply). Materials and Methods: Two metallic matrices molded in polyvinyl siloxane provided 30 cylindrical test specimens for the diametral compression test and 30 hemispherical test specimens for the surface rugosity test. The cylindrical test specimens were submitted to tests of diametral compression strength using a DL2000 universal assay machine, with a load cell of 2000 Kgf and constant speed of 1 mm/min connected to the software. Kruskal–Wallis and Dunn's nonparametric tests were used to analyze the results. The hemispheres were submitted to the surface rugosity assay using a SJ201-P rugosimeter with a sensitivity of 300 μm, speed of 0.5 mm/s, and cut-off of 0.8 mm, and the readings were taken on the convex surface of the test specimens and metallic matrix. Results were analyzed using with Fisher's least significant differences test (LSD) and Dunnett's test. Results: Kruskal–Wallis test showed significant difference between die materials for diametral compression strength (P = 0.002). Dunn's test showed significantly higher values for modified polyurethane resin (Exakto-Form). The gypsum type IV, which did not significantly differ regarding diametral compression strength, showed 34.0% (Durone) and 42.7% (Fuji Rock) lower values in comparison to Exakto-Form. Conclusion: Within the parameters adopted in this study, it is possible to conclude that Exakto-Form polyurethane resin showed higher resistance to compression and was closer to the metallic matrix rugosity, and, along with the gypsum type IV Durone, showed better reproducibility of details relative to the Fuji Rock.

DOI:10.4103/2231-0762.200705  PMID:28316948
Aims and Objectives: Considerable importance to oral health care was lacking in India, and oral health neglect continues to exist, which is evident in the low utilization rates and poor oral health status. Conventional dentures are the most common alternative in restoration of lost teeth. Without proper denture care practices, there is an increased risk of developing a multitude of problems. The aim of this study is to assess the denture care practices among complete denture wearers in East Godavari district, Andhra Pradesh. Materials and Methods: A cross-sectional study was conducted in the department of Prosthodontics at the Konaseema Institute of Dental Sciences, Amalapuram, Andhra Pradesh. Patients with self-care ability and adequate overall health who were using either single or full complete dentures for more than 6 months from the time of the study were requested to participate in the study. A total of 375 study participants were given a self-administered questionnaire on denture care practices followed by clinical examination of the denture status. Statistical analysis was done using the Statistical Package for the Social Sciences software for windows, version 20.0 (Armonk, NY: IBM Corp). Results: The majority of participants reported cleansing their dentures once a day, with brush and water, and had the habit of removing the dentures at night. Almost 80% of the participants reported their denture status to be good/fair. Clinical examination revealed that slightly more than half of the participants had poor denture status. Conclusion: This study highlights the need for improvement in patient education and counseling with respect to the maintenance of dentures and upkeep of denture hygiene. It also emphasizes the need for educating patients on how to evaluate the status of their dentures.

Satheesh B Haralur, Osama A Hamdi, Abdulaziz A Al-Shahrani, Sultan Alhasaniah
January-February 2017, 7(1):52-57
DOI:10.4103/jispcd.JISPCD_483_16  PMID:28316950
Aim: To evaluate the effect of varying cellulose casting ring liner length and its prewetting on the marginal adaptation and dimensional accuracy of full veneer metal castings. Materials and Methods: The master die was milled in stainless steel to fabricate the wax pattern. Sixty wax patterns were fabricated with a uniform thickness of 1.5 mm at an occlusal surface and 1 mm axial surface, cervical width at 13.5 mm, and 10 mm cuspal height. The samples were divided into six groups (n = 10). Groups I and II samples had the full-length cellulose prewet and dry ring liner, respectively. The groups III and IV had 2 mm short prewet and dry cellulose ring liner, respectively, whereas groups V and VI were invested in 6 mm short ring liner. The wax patterns were immediately invested in phosphate bonded investment, and casting procedure was completed with nickel-chrome alloy. The castings were cleaned and mean score of measurements at four reference points for marginal adaption, casting height, and cervical width was calculated. The marginal adaption was calculated with Imaje J software, whereas the casting height and cervical width was determined using a digital scale. The data was subjected to one-way analysis of varaince and Tukey post hoc statistical analysis with Statistical Package for the Social Sciences version 20 software. Results: The group II had the best marginal adaption with a gap of 63.786 μm followed by group I (65.185 μm), group IV (87.740 μm), and group III (101.455 μm). A large marginal gap was observed in group V at 188.871 μm. Cuspal height was more accurate with group V (10.428 mm), group VI (10.421 mm), and group II (10.488 mm). The cervical width was approximately similar in group I, group III, and group V. Statistically significant difference was observed in Tukey post hoc analysis between group V and group VI with all the other groups with regards to marginal adaptation. Conclusion: The dry cellulose ring liners provided better marginal adaptation in comparison to prewet cellulose ring liners. Accurate cuspal height was obtained with shorter ring liner in comparison to full-length cellulose ring liners.
