Sublingual crescent extension: A solution for loose lower denture
Nishna Pradeep, Jinsa P Devassy, AV Sreekumar
January-June 2015, 1(1):66-68
DOI:10.4103/2454-3160.161822  
Mandibular complete dentures frequently lack retention and stability and offer less denture-supporting area than maxillary dentures. In case of severely resorbed ridges retention is highly compromised. Extending the anterior lingual flange of the lower denture sublingually makes it possible to achieve satisfactory retention in severely resorbed ridges. This clinical report describes a simpler method to achieve retention during impression making and thus help to maintain the retention and stability of lower dentures during the function.

What is a glide path?
Sachin Passi, Nisha Kaler, Nandini Passi
July-December 2016, 2(2):32-37
DOI:10.4103/2454-3160.202220  
Three-dimensional cleaning, shaping, and obturation of root canal system can be considered as foundations for a predictable endodontic success. One guiding strategy that has emerged as a critical part of endodontic success is the creation and maintenance of a glide path. Without it, cleaning and shaping become unpredictable because there is no guide for endodontic mechanics. Thus, a smooth glide path is the secret to safe and successful rotary shaping. However, this subject of glide path has no formal training in the endodontic curricula in most of the dental schools worldwide. The purpose of this review article is to serve as a reference guide for endodontic glide path preparation. Knowing what to do is only half of the job, implementing different skills in day-to-day clinical practice will accomplish the job fully, ensuring successful endodontic treatment outcomes.

Dual impression technique for fabrication of maxillary complete immediate denture
Ashish Kumar Srivastava, Ujjal Chaterjee, Madhu Ranjan, Arunoday Singh
July-December 2016, 2(2):42-45
DOI:10.4103/2454-3160.202218  
Conventional complete denture apart from all its merits has the prominent disadvantage of leaving the patient for a brief period of edentulous state till definitive prosthesis can be fabricated. Therefore, the concept of immediate denture is to preserve the jaw relation, keep the patient habituated to the complete denture and in the process preserve the esthetic concern of the patient. In the process, the psychological well-being of the patient is preserved as the patient is not without teeth for any prolonged period. The challenge in this technique is to record the edentulous and dentulous portion of the arch in conjecture with each other so that the final impression is closest to the intraoral situation, enabling us to provide the best results in short-and long-term of complete denture fabrication.

January-June 2015, 1(1):28-32
DOI:10.4103/2454-3160.161798  
Introduction: Plants have been used for health disorders and to prevent diseases including epidemics since times immemorial. The knowledge of their healing properties has been transmitted over the centuries within and among human communities. Aims and Objectives: To evaluate and compare the antimicrobial potential of herbal extracts, namely neem (Azadirachta indica), tulsi (Ocimum sanctum), bitter gourd (Momordia charantia), and arka (Calotropis procera) as endodontic irrigants against Enterococcus faecalis and Candida albicans in vitro. Materials and Methods: Agar well diffusion test was performed. The inoculums of E. faecalis and C. albicans were streaked on the blood agar plate, and wells were made using cork borers. The prepared herbal extracts of the test samples were loaded onto agar plate. The plates were incubated at 37°C for 24 h. The inhibition zones indicating the antimicrobial potential were measured using a millimeter scale and results were analyzed statistically. Results: Bitter gourd showed the maximum zones of inhibition followed by neem, tulsi, and calotropis for both E. faecalis and C. albicans. Conclusion: The tested irrigants showed significant antimicrobial efficacy against E. faecalis and C. albicans. Thus, the use of herbal alternatives as root canal irrigants might prove advantageous considering the undesirable characteristics of presently used irrigants.

Anurag Saxena, Syamantak Srivastava, Amiya Agrawal, Shipra Singh, Harmurti Singh, Anand Kumar, Ruchika Khanna, Ram K Srivastava
July-December 2015, 1(2):96-100
DOI:10.4103/2454-3160.177934  
Objective: The objective is to analyze most popularized xylocaine and to compare the adequacy of analgesia achieved and the effects of xylocaine hydrochloride 2% without adrenaline and xylocaine hydrochloride 2% with adrenaline (1:200,000), used as local anesthetics in dentistry for extraction of tooth. Materials and Methods: Two hundred and fifty patients of varying age and sex, requiring at least extraction of two teeth, were picked from the outpatient department of oral and maxillofacial surgery. In each patient, two teeth were extracted under local anesthesia, one under xylocaine plain and other under xylocaine with adrenaline. Time of onset, depth, and duration of analgesia were recorded. Conclusion: Lidocaine with epinephrine (1:200,000) local anesthesia efficacy in dental extractions is more effective than lidocaine without adrenaline in extraction of tooth, and the onset, duration, and depth of analgesia of xylocaine hydrochloride with adrenaline were good as compared to plain xylocaine (xylocaine without adrenaline). Thus, lignocaine as a local anesthetic may be an effective drug in dental extractions with the higher safety margin.

Single canal in a single-rooted mandibular second molar: An enigma
Sonu Acharya
July-December 2016, 2(2):50-52
DOI:10.4103/2454-3160.202221  
The case report here tries to describe the variation of root canal anatomy in a second mandibular molar, which is rare in occurrence in literature. This case report presents a relatively rare case of mandibular second molar with single root and a single root canal in a 45-year-old female patient who had come to dental clinic with a complain of pain in the left lower tooth region. Ambiguity in the canal morphology of the second molar is quite common. Knowledge of variations in internal anatomy of teeth is important for success in endodontic treatment. Root canal morphology is limitless in its variability and clinicians must be aware that anatomic variations constitute a formidable challenge to endodontic success. Hence, clinicians have to take utmost care when these cases with single canal and single root come to clinic.

Satnam Singh, Kamaljit Kaur, Akshat Gupta, Gyan R Sahu
January-June 2015, 1(1):59-61
DOI:10.4103/2454-3160.161814  
Eagle's syndrome, also known as an elongated styloid process, is a condition that may be the source of craniofacial and cervical pain. It is infrequently reported but is probably more common than generally considered. The symptoms related to Eagle's syndrome can be confused with those attributed to a wide variety of facial neuralgias and/or oral, dental, and temporomandibular joint diseases. Surgical treatment is considered as the best option to remove the styloid process to its normal limit through extraoral or intraoral techniques. We are reporting a case and reviewed the recent literature of trans-oral extratonsillar approach without tonsillectomy and advantage such as simple, time-saving, and without any extra oral scar.

Sumeeta Sandhu, Jagmohan Lal, Ramanpreet Singh, Rameet Sandhu, Jobanjeet Sra
January-June 2016, 2(1):7-10
DOI:10.4103/2454-3160.202121  
Healthy mouth needs a stable occlusal relationship to help in efficient mastication, maintaining vertical dimension of the face, stabilizing the arches, and protecting the soft tissues. Restorative dentistry loses its significance in the absence of good occlusion. Poorly occluding restored tooth surfaces not only provide a deleterious effect to the tooth and its associated periodontium but also to the dentition of the opposing arch. The damaging effects of premature contacts, cuspal interferences, faulty proximal contacts, etc., have an adverse influence on the overall health of stomatognathic system. In this article, the significance of establishing occlusal anatomy while restoring teeth to maintain healthy and harmonious occlusion has been described.

Herbal dentistry: A boon
Neeraj Grover, Sandeep Sharma, Sanjeet Singh, Jyoti Sharma
January-June 2015, 1(1):8-10
DOI:10.4103/2454-3160.161794  
Oral health influences the general quality of life and poor oral health is linked to chronic conditions and systemic diseases. Inter-relationship of oral diseases and the oral microbiota is well established. A number of species of bacteria that are inhabitant of the oral cavity are also implicated in oral diseases. Various plant species like Garlic, lemon, walnut and their extracts are now a days used in place of allopathic drug regimen because of near to minimum side effects. The advent and progression of dental caries involves acid producing gram-positive and gram negative bacteria and these bacterial strains have also been seen as the cause of periodontal diseases. Keeping in view the adverse effects of the various medications used in dentistry such as vomiting, diarrhoea and tooth staining and financial considerations in developing countries, there is a need for a safe and effective alternative and treatment options. Natural medicinal extracts isolated from plants come as good alternatives as they inhibit the growth of oral pathogens thereby reducing the development of biofilm on the tooth thus reducing the symptoms of oral diseases thereby enhancing the immunity.

Pooja Ahluwalia, Parampreet Pannu, Sanjam Kalra, Aninditya Kaur, Dikshit Behl, Ramandeep Singh Gambhir
January-June 2015, 1(1):16-21
DOI:10.4103/2454-3160.161796  
Background: Avulsion is defined as complete displacement of a tooth from its socket after trauma. The most accepted treatment for an avulsed permanent tooth is immediate replantation. Children spend a considerable amount of waking hours in school where teachers are the primary caregivers. Hence, this study was carried out to evaluate knowledge and attitudes of school teachers regarding the emergency management of an avulsed tooth in the district of Patiala, Punjab. Materials and Methods: A two-stage sampling process was used which involved the sampling of schools within the educational district followed by sampling of teachers in the selected schools. A self-structured pretested questionnaire was personally administered to 500 school teachers of district Patiala. Statistical analysis was done using frequency and percentages and descriptive statistics like Student's t-test. Results : Almost half of respondents were aware of mouth guards. 82.8% felt that treatment should be carried out immediately after injury. Approximately, one-fourth of respondents (25.6%) believed that knocked out tooth cannot be saved so no attempt should be made at cleaning it. There was a statistically significant association of knowledge regarding replantation of tooth with education level and training in first aid. Conclusion: The present study revealed that overall knowledge regarding the emergency management of avulsed tooth was low in teachers. There is a need of first aid training to all the teachers along with emergency management of dental trauma.

Ashok Suman, Jagvinder Singh Mann, Sumeeta Sandhu, Sonal Maurya
January-June 2017, 3(1):4-10
DOI:10.4103/sidj.sidj_2_18  
Aims: The aim of this study is to evaluate the hardness and degree of conversion (DC) of different bulk-fill materials when cured with the Quartz Tungsten Halogen (QTH) and Light emitting diode (LED) devices using same energy density. Settings and Design: This was in vitro study. Materials and Methods: Three different bulk-fill materials, i.e., Filtek™ [3M ESPE], Tetric® N-Ceram [Ivoclar Vivadent], and SDR (Smart Dentin Replacement) by Dentsply Caulk, were used for making 180 samples (60 samples each) in Teflon mold. Out of these 60 samples, samples of three heights were prepared, i.e., 2 mm, 4 mm, and 6 mm (20 each). All the sample molds were filled in single increment and were exposed to the QTH and LED using the same energy density. Then, these samples were tested for microhardness using the Vickers hardness (VH) testing machine (Mitutoyo, Japan) and DC using Fourier Transform Infrared Spectroscope (Cary 630 FTIR Agilent Technologies, Germany). Statistical Analysis Used: The statistical analysis was performed on the collected data. The Kolmogorov–Smirnov and Shapiro–Wilk tests showed that the data are normally distributed. Since all the variables were continuous and statistically independent, independent t-test was applied to compare mean values of VH and DC of inter groups. Results: The statistical analysis of readings revealed that there was no significant difference in the mean values of microhardness and % DC for both groups cured by QTH and LED. Conclusions: It can be concluded that irrespective of the type of the light cure unit if the energy density applied is same then almost similar performance can be expected from the devices.

Collagen as a scaffold in regenerative endodontic treatment of necrotic immature permanent tooth
Neelam Mittal, Shreya Sharma
January-June 2015, 1(1):47-49
DOI:10.4103/2454-3160.161803  
Regenerative endodontics is now an established treatment modality for necrotic immature permanent teeth. This case report describes the treatment of a necrotic immature permanent maxillary central incisor with crown fracture using a regenerative approach instead of the conventional apexification procedure. The necrotic root canal was gently debrided, irrigated and then medicated with triple antibiotic paste. At 1-month recall appointment, the tooth was asymptomatic. Bleeding was induced by filing the canal beyond the apex and collagen was placed along with induced blood clot. After 12 months follow-up, healing of periapical lesion, progressive thickening of the root canal walls, and apical closure was radiographically evident. This suggests that regenerative endodontic treatment is an appropriate treatment modality for the management of necrotic immature permanent teeth. Collagen scaffold combined with bleeding induction results in apical closure in immature teeth.

Guneet Juneja, Vipin Bharti
January-June 2015, 1(1):22-27
DOI:10.4103/2454-3160.161797  
Objective: The aim of the present study was to compare autologous platelet-rich fibrin (PRF) combined with a porous hydroxyapatite bone graft to porous hydroxyapatite bone graft alone in the treatment of periodontal intrabony defects clinically and radiographically using Dentascan. Materials and Methods: In a split-mouth study design, 10 patients suffering from generalized chronic periodontitis, having two almost identical intrabony defects with probing pocket depth of at least 5 mm were selected for the study and randomly divided into two groups. In Group I periodontal flap surgery followed by placement of porous hydroxyapatite bone graft was done and in Group II, periodontal flap surgery followed by placement of a homogenous mixture of PRF and porous hydroxyapatite bone graft was done. All the clinical parameters were recorded at baseline, 3 and 6 months postoperatively and radiographic parameters were recorded at baseline and 6 months postoperatively. Results: There was statistically significant reduction in probing pocket depth and gain in clinical attachment level in both groups. On comparison Group II showed statistically significant more probing pocket depth reduction than Group I at all-time intervals. There was statistically significant mean defect fill and mean defect resolution observed in both groups at all-time intervals. However, the intergroup comparison was statistically nonsignificant. Conclusion : Within limits of the study it may be concluded that a combination of PRF with porous hydroxyapatite bone graft demonstrated better results as compared to porous hydroxyapatite bone graft alone in the treatment of periodontal intrabony defects. Spiral multislice computed tomography equipped Dentascan provides three-dimensional images of excellent quality for evaluating the morphology of the periodontal bone defects. Its use in ascertaining the various defect parameters in the periodontal treatment of intrabony defects is promising.

DOI:10.4103/2454-3160.177929  
Osseointegration, i.e., structural and functional union of the surface of dental implant with surrounding bone is paramount for the success of device. In recent years, osteogenesis at the bone-implant interface has been induced by structural modifications of the implant surface, particularly at the nanoscale level. This has been achieved through modulation of osteoblast adhesion. There is strong belief that nanoscale features in materials processing is truly a new frontier. This paper reviews recent advances in fabrication of novel coatings and nanopatterning of dental implants and their subsequent cellular interactions, leading to an improvement in osseointegration and hence the long-term clinical success of the "third dentition" i.e., dental implants.

Cone beam computed tomography in orthodontics
Sumreet Kaur Sandhu
January-June 2017, 3(1):1-3
DOI:10.4103/sidj.sidj_1_18  
A new revolution in three-dimensional radiologic advances in dentistry was introduced in the year 1998, as cone beam computed tomography (CBCT). Over the years, it has become an increasingly popular technique in orthodontic diagnosis, treatment planning, and research. This rise in its popularity has been facilitated by the relative advantages of three-dimensional (3D) over 2D radiography. CBCT imaging involves only a minimal increase in radiation dose relative to combined diagnostic modern digital panoramic and cephalometric imaging. A combination of volumetric reconstruction and multiplanar views can provide the orthodontic clinician with skeletal hard tissue, soft tissue, dentition, and airway information. Despite many suggested indications of CBCT, scientific evidence that its utilization improves diagnosis and treatment plans or outcomes has only recently begun to emerge. This article provides a comprehensive review of the application of CBCT in orthodontics. The current indications for CBCT in standard orthodontic diagnosis include impacted teeth, cleft lip, and palate and skeletal discrepancies requiring surgical intervention, root resorption, supernumerary teeth, temporomandibular joint (TMJ) pathology, facial asymmetry, temporary anchorage devices, root morphology and angulation; alveolar boundary conditions; maxillary transverse dimensions and maxillary expansion, and vertical malocclusion. Advanced CBCT software applications can be used to quantify airway space in the cases of obstructive sleep apnea, perform superimpositions to semiquantitatively visualize changes over the hard and soft tissues, including the TMJ and airway.

Anuj Wangoo, Sakshi Malhotra, Ramanpreet Singh, Yashendra
July-December 2015, 1(2):117-120
DOI:10.4103/2454-3160.177946  
Overdentures is a preferred treatment option in patients who have to go for extraction of the remaining teeth for fabrication of complete dentures. The teeth which are preserved, play a vital role by improvement of crown root ratio, provide proprioception, decrease the rate of resorption, and improve support to the denture. Rehabilitation using overdentures is a widely accepted preventive approach due to its ease of fabrication and the successful prognosis. An over denture is a preventive prosthodontic concept with a multidisciplinary approach involving periodontic, endodontic, and prosthodontic intervention. An overdenture improves retention, stability, maintains proprioception, prevents residual ridge resorption, and improves patient satisfaction. This is a case report of a patient with few remaining teeth, successfully treated with Preci-Sagix (Ceka attachments Preci-line, Belgium) overdenture attachments.

Ruhi Bajaj, Meenu Garg, Salil Pawah, Ramesh Gupta
January-June 2017, 3(1):11-14
DOI:10.4103/sidj.sidj_5_17  
Papillon–Lefevre syndrome is a rare autosomal recessive disorder, in which the clinical manifestations are periodontitis which results in premature loss of both deciduous and permanent teeth and palmoplantar keratinization. The palmoplantar keratoderma typically has its onset between the ages of 1 and 4 years and severe periodontitis starts at the age of 3 or 4 years. The deciduous teeth frequently fall out by about age five and most of the permanent teeth may also be lost by approximately age 17. In the present case, a young, edentulous male of this syndrome having most the characteristic features was treated by modified complete denture prosthesis considering his young age and low socioeconomic status.

January-June 2015, 1(1):50-55
DOI:10.4103/2454-3160.161807  
Amelogenesis imperfecta has been described as a group of hereditary enamel defects not associated with systemic diseases. Restoration of these defects is important not only because of esthetic and functional concern, but also because there may be a positive psychological impact on the patient. Among various treatments described for rehabilitation of amelogenesis imperfecta, this case report described the rehabilitation of patient utilizing twin stage procedure with aim of improving patient's function, appearance, restoring the proper contacts, and simplifying the prosthetic clinical and lab work procedures. Twin stage procedure is based on the fact that prevents horizontal forces acting during various mandibular excursion in full mouth rehabilitation case, to control horizontal forces which in turn depends upon the condylar path, incisal path, and cusp angle. Among them, role of cusp angle is more supported whereas condylar path and incisal path role is considered unreliable.

January-June 2015, 1(1):33-38
DOI:10.4103/2454-3160.161799  
Introduction: A well-fitted root canal filling prevents percolation and microleakage of periapical exudate into the root canal space, prevents reinfection and creates a favorable biological environment for healing to take place. Several techniques using gutta-percha have been used in an attempt to achieve a void-free, homogeneous filling. Aim: Three different obturation techniques that are Thermafil obturation, cold lateral condensation and warm vertical condensation using rotary canal technique were compared. Materials and Methods: This study was in vitro study. Forty-five extracted permanent human premolars with single canal, and fully developed apices were selected for the study. Statistical Analysis: This was done with the help of analysis of variance. Results: There was leakage measuring 0.5-3.5 mm in 73.3% of roots in group I, 80% in group II and 40% in group III. Similarly, the leakage was 3.51-6.5 mm in 20% of the roots in group I, 13.3% in group II and group III. The leakage was found to be more than 6.5 mm in 6.7% of the roots in group I and II and 46.7% in group III. There was sealer extrusion in two teeth in group I and II and in four teeth in group III. Conclusions: It was observed that the warm vertical condensation and lateral condensation techniques were more effective in restricting apical dye penetration. However, the results of this in vitro study need to be confirmed by further in vivo research.

DOI:10.4103/2454-3160.177930  
In dentistry, ceramics are often referred to as nonmetallic, inorganic structures primarily containing compounds of oxygen with one or more metallic or semimetallic elements. They are composed of sodium, potassium, calcium, magnesium, aluminum, silicon, phosphorus, zirconium, and titanium. Structurally, dental ceramics contain a crystal phase and a glass phase based on the silica structure, characterized by silica tetrahedra, containing central Si4+ ion with four O− ions. Biocompatibility, esthetics, durability, and easier customization properties have led to the increased usage of ceramics. The specialty of ceramic teeth is its ability to mimic the natural tooth in color and translucency along with its strength. Ceramics have excellent intraoral stability and wear resistance adding to their durability. Basically, the inorganic composition of teeth and bones are ceramics which is hydroxyapatite. Over the past few years, the technological evolution of ceramics for dental applications has been incredible, as new materials and processing techniques are being introduced. The improvement in strength, as well as toughness, has made it possible to expand the range of indications to long-span fixed partial prostheses, implant abutments, and implants. While porcelain-based materials are still a major component in dental science, there have been moves to replace metal ceramics systems with all-ceramic systems. Numerous all-ceramics are being developed which is highly esthetic, biocompatible to tissue, and long-lasting in nature. Advances in computer-aided design/computer-aided manufacturing technologies have led to immense popularity of high-strength ceramic materials. These materials are highly esthetic, biocompatible to tissue, and long-lasting in nature. In this review, we will discuss all-ceramic materials which are used in dentistry.
