CASE REPORTS
Mental nerve paraesthesia: A review of causes and two endodontically related cases
Unni Krishnan, Alex J Moule
May-August 2015, 5(2):138-145
DOI:10.4103/1658-5984.155454  
Mental nerve paraesthesia can occur as a result of a variety of reasons. Paraesthesia following endodontic treatment is an uncommon treatment complication. Causes of paraesthesia in the mental nerve region are reviewed and two cases involving endodontic treatment are discussed. In the first instance, a patient presented with difficulty in swallowing and severe pain localized to her right mandible, with numbness of her lower lip. Paraesthesia resolved quickly with endodontic treatment. In the second instance, a patient referred for treatment a mandibular second premolar developed profound paraesthesia in the distribution of the mental nerve after treatment. The local anesthetic used was 4% articaine by infiltration. CBCT imaging revealed two accessory mental foramen and slight extrusion of sealant into one of the neurovascular exits. Possible causes of paraesthesia are discussed in the light of the literature review. CBCT imaging may be useful in the diagnosis and management of these conditions.

The anatomy of the root apex: A review and clinical considerations in endodontics
Osama S Alothmani, Nicholas P Chandler, Lara T Friedlander
January-April 2013, 3(1):1-9
DOI:10.4103/1658-5984.116273  
Studies on the anatomy of the root apex are an area of interest to the endodontist; they have reported that the position of the apical constriction, apical foramen and the cemento-dentinal junction varies across the tooth types. These anatomical apical landmarks are considered extension limits for root canal instrumentation and filling. Achieving an optimum working length is thought essential for successful root canal treatment, so adopting any of these landmarks is associated with certain risks and benefits. The variability in the position of the apical constriction and apical foramen, for example, complicates their clinical detection, while the cemento-dentinal junction is a histological landmark that cannot be detected clinically. The radiographic apex does not always coincide with the anatomic apex of the tooth. The pre-operative status of the pulp must be considered while obtaining the working length. Most prognostic studies agree that extending the root filling to within 2-3 mm of the radiographic apex is associated with favorable treatment outcomes.

September-December 2014, 4(3):141-144
DOI:10.4103/1658-5984.138148  
Iatrogenic root perforations, which may have serious implications, occur in approximately 2-12% of endodontically treated teeth. Successful management of root perforations is dependent on early diagnosis of the defect, location of the perforation, choice of treatment, materials used, host response, and the experience of the practitioner. This report presents the successful management of an iatrogenic perforation in a tooth with radiographic evidence of pulp canal obliteration.

Abdullah Mahmoud Riyahi, Abdelhamied Y Saad
January-April 2018, 8(1):55-57
DOI:10.4103/sej.sej_100_16  
The aim of this work was to present a case report describing lower lip paresthesia following failed endodontic treatment and development of periapical lesion. A 42-year-old female presented difficulty in swallowing with pain in right mandibular second premolar and numbness in the right side of her lower lip. Radiographic examination revealed inadequate root canal and a large periapical lesion in the mental nerve area. The lesion appeared extending into the inferior alveolar canal causing irritation of inferior alveolar nerve and its mental branch. Following root canal retreatment, there was improvement of the clinical symptoms and gradual reduction in size of the lesion. A full resolution of symptoms was demonstrated 4 months after successful endodontic therapy. It was concluded that careful clinical and radiographic diagnosis followed by proper endodontic treatment proved to be successful in treating lower lip paresthesia occurred following failed root canal therapy.

Management of a large radicular cyst: A non-surgical endodontic approach
Shweta Dwivedi, Chandra Dhar Dwivedi, Thakur Prasad Chaturvedi, Harakh Chandra Baranwal
September-December 2014, 4(3):145-148
DOI:10.4103/1658-5984.138149  
A radicular cyst arises from epithelial remnants stimulated to proliferate by an inflammatory process originating from pulpal necrosis of a non-vital tooth. Radiographically, the classical description of the lesion is a round or oval, well-circumscribed radiolucent image involving the apex of the tooth. A radicular cyst is usually sterile unless it is secondarily infected. This paper presents a case report of conservative non-surgical management of a radicular cyst associated with permanent maxillary right central incisor, right lateral incisor and right canine in a 24-year-old female patient. Root canal treatment was done together with cystic aspiration of the lesion. The lesion was periodically followed up and significant bone formation was seen at the periapical region of affected teeth and at the palate at about 9 months. Thus, nonsurgical healing of a large radicular cyst with palatal swelling provided favorable clinical and radiographic response.

Mothanna Al-Rahabi, Abdul Mujeeb Abdulkhayum
May-August 2012, 2(2):80-84
DOI:10.4103/1658-5984.108156  
The main objective of performing root canal therapy is to eliminate bacteria from the infected root canal system or remove inflamed pulp tissue and close it with a biologically acceptable filling material. If this treatment managed well, regardless of the number of visits, it will create a favorable environment for healing. The recent advances in Endodontic technology, attracts the dental practitioners as well as the Endodontist to perform the root canal treatment in one visit. The question that we consider in this review article focuses on the long term prognosis of one-and multiple appointment endodontic therapy for teeth with vital pulp, necrotic pulp, and apical periodontitis .

A. R. Vivekananda Pai, Rachit Jain, Ashwini S. Colaco
May-August 2014, 4(2):77-82
DOI:10.4103/1658-5984.132723  
Radix entomolaris (RE) is considered to be an Asiatic trait. However, its prevalence in Indian population is found to be lower than in other Asian races. Nevertheless, its awareness and identification is vital to achieve endodontic success. This article presents a review on clinical approach and a case series on the detection and endodontic management of RE in mandibular first molars. Radix entomolaris was detected by identifying the presence of a double or extra root outline in the preoperative radiograph, modifying the access opening and closely inspecting the pulp chamber and was endodontically treated following cleaning, shaping, and obturation of the canals. Achieving the endodontic success in the presence of an RE requires knowledge about its prevalence, diagnosis, morphology, canal configuration, and clinical approach.

Radiographic assessment of endodontic working length
Osama S Alothmani, Lara T Friedlander, Nicholas P Chandler
May-August 2013, 3(2):57-64
DOI:10.4103/1658-5984.118145  
The use of radiographs for working length determination is usual practice in endodontics. Exposing radiographs following the principles of the paralleling technique allows more accurate length determination compared to the bisecting-angle method. However, it has been reported that up to 28.5% of cases can have the file tip extending beyond the confines of the root canals despite an acceptable radiographic appearance. The accuracy of radiographic working length determination could be affected by the location of the apical foramen, tooth type, canal curvature and superimposition of surrounding structures. Variations among observers by virtue of training and experience may also influence the accuracy of the procedure. The interpretation of radiographs could be affected by film speed and viewing conditions, with the superiority of digital imaging over conventional radiography for working length determination remaining debatable. The combination of several methods is recommended for acquiring the most accurate working length.

Crown discoloration due to the use of triple antibiotic paste as an endodontic intra-canal medicament
Manuel Sebastian Thomas
January-April 2014, 4(1):32-35
DOI:10.4103/1658-5984.127985  
The use of triple antibiotic paste (TAP) (mixture of ciprofloxacin, metronidazole and minocycline) as an intra-canal medicament have shown very encouraging results particularly in non-vital immature teeth associated with periradicular lesions. Hence, before opting for a surgical approach, a non-surgical approach can be thought of with extended use of TAP as intra-canal medicament, especially in patients who are phobic to invasive procedures. On the flip side, the use of TAP has few side-effects, of which one is the discoloration it can cause due to the presence of minocycline in the mix. The purpose of this article is to presents a case of coronal discoloration due to the use of TAP as an endodontic intra-canal medicament.

Bernard Y Tumbelaka, Fahmi Oscandar, Faisal Nur Baihaki, Suhardjo Sitam, Mandojo Rukmo
September-December 2014, 4(3):115-121
DOI:10.4103/1658-5984.138139  
Objectives: The aim of the present research was to identify pulpitis through periapical radiography by applying edges as basis image features, the texture description and the artificial neural networks (ANNs). Materials and Methods: Input image data records of 10 molar and 10 canine teeth were used. The clinical diagnosis of interest cases were represented as normal pulp, reversible and irreversible pulpitis, and necrotic pulp. The following image processing steps were done. First, the data records were converted digitally and preprocessed as its original image using the Gaussian Filter to obtain the best smoothed intensity distribution. Second, the local image differentiation was used to produce edge detector operators, e(x,y) as the image gradient; ∇f(x,y) providing useful information about the local intensity variations. Third, these results were analyzed by using the texture descriptors to obtain digitally the image entropy, H. The fourth step, all were characterized by the ANNs. Results: The edge detection carried important information about the object boundaries of pulpal health and pain conditions in the dental pulp significantly. The image entropy which was identified, the diagnostic term, was obtained from texture descriptors in the segmentation regions where the curves of pulp states tent convergence with the normal pulp line from 4.9014 to 4.6843 decreasing to the reversible and the irreversible pulpitis line include the nectrotic pulp line from 4.6812 to 4.5926 and then inputting to the ANNs analysis at the same of mean square error around 0.0003. Conclusions: Referred to these results, the correlation of the image entropy and the ANNs analysis could be linearly classified with the critical point of 4.6827. Finally, it could be concluded that the direct reading radiography is better to be digitized in order to provide us the best choice for diagnosis validation.

Natural products as storage media for avulsed tooth
Deepika Jain, Pralhad L Dasar, Sandesh Nagarajappa
May-August 2015, 5(2):107-113
DOI:10.4103/1658-5984.155448  
Avulsion of tooth is complete displacement of tooth out of its socket that results in mutilation of periodontal ligaments. The desirable treatment option is replantation of the tooth. However, unsuccessful replantation is a matter of great discontentment. Unsuccessful replantation is due to inappropriate management of the avulsed tooth. Protection of teeth from desiccation due to drying of the periodontal ligament tissue, by keeping it in storage media can improve the outcome of the treatment. This review paper focuses on the use of natural products as storage media for avulsed teeth. In vitro and in vivo research published during 1995-2014, allowing open access on National Center for Biotechnology Information (NCBI) database and articles on EBSCO host (EBSCO-Elton B. Stephens Company) were included. It was found that natural products such as milk, coconut water, propolis, green tea, red mulberry, Aloe vera, egg-white and pomegranate have shown ability to maintain viability of periodontal ligament cells of avulsed teeth. Few natural products such as coconut water and milk can be used in raw form, while other products such as green tea and red mulberry need processing. Ability to maintain periodontal cell viability for a longer time is warranted in cases of major accidents, where teeth can be replanted only after other major surgeries. Natural products have easy availability, greater efficacy and longer storage time as compared to Hank's balanced salt solution which has been recommended by the International Association of Dental Traumatology as standard solution for storage of avulsed teeth. Natural products have shown good qualities in in vitro experiments; further in vivo studies are needed to evaluate their efficacy as storage media.

The accuracy of Root ZX electronic apex locator
Osama S Alothmani
September-December 2012, 2(3):115-130
DOI:10.4103/1658-5984.112702  
The aim of this review was to evaluate studies assessing the accuracy of Root ZX when used for working length determination in permanent teeth and to identify factors affecting the device's precision. An electronic search for articles published in English language since 1994 was conducted on the Medline via Ovid interface. All issues of the International Endodontic Journal, Journal of Endodontics and Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology and Endodontology since 1994 were manually searched. The reference lists of review articles were cross-referenced to identify any potential publications. A total of 76 publications fulfilled the inclusion criteria. The studies varied in their methodologies, and most of them did not adhere to the manufacturer's recommendations while operating the device. The Root ZX failed to consistently detect the apical constriction or the apical foramen. Nonetheless, it mostly allowed file tip placement in the area bounded by these two landmarks, especially when the 0.5 mark of its digital meter was adopted. Tooth-related factors potentially influencing the precision of Root ZX included pre-operative pulp status, tooth type, position of the apical foramen, canal obliteration, and the size of apical diameter. Operative factors including coronal pre-flaring, presence or absence of irrigants, file size, file alloy, and mode of file operation could also influence the performance of Root ZX. In conclusion, adopting the 0.5 mark of the digital meter of the Root ZX reduces chances of violating the apical foramen. Further, factors influencing the precision of Root ZX must be considered while operating it.

Abdullah A Al Shareef, Abdelhamied Y Saad
September-December 2013, 3(3):107-113
DOI:10.4103/1658-5984.121502  
This investigation presents a chart that can assist clinicians, in general and endodontists, in particular, in making the right decision when they are deciding, which rout to take; endodontic treatment to save the natural tooth or extraction and osseointegrated implant. Systematic review of the literature was used to investigate success rates of both endodontic therapy and extraction of the tooth and placement of an implant, with the intent of determining the superior treatment modality. The results demonstrated that both treatment modalities produced nearly similar success rates, with implants generally showing slightly higher success rates. It was concluded that endodontic treatment should first be given to save compromised natural tooth before pursuing extraction and implant. A protocol to assist clinicians in making the right decision to endodontically save or extract the offending tooth and replacement of implant is presented.

Ahmed Jamleh, Lama Awawdeh, Hajar Albanyan, Emad Masuadi, Khalid Alfouzan
September-December 2016, 6(3):131-135
DOI:10.4103/1658-5984.189355  
Aims: The aim of this study was to investigate the degree of tug-back after canal preparation with respect to the Gutta-percha-occupied area (GPOA). Materials and Methods: Roots of twenty premolar teeth were prepared till size 35/0.04, then GP cones of same size and taper were adapted to root canals and the degree of tug-back sensation was scored as loose, slight, adequate, and strong. Root canals were filled with GP and AH26 sealer, and then sectioned horizontally 1 mm from the apical end at three levels. GPOA and its sum from the three levels sum of GPOA (sGPOA%) were calculated using digital stereomicroscope. Statistical Analysis: At each sectioned level, GPOA% was compared with the score of tug-back sensation using one-way ANOVA at a 5% significance level. Multiple pairwise comparisons were performed using Tukey test. Results: Tug-back sensation was present in all canals, described as slight, adequate, and strong in 4, 8, and 8 canals, respectively. Among the tug-back scores, quantitative analyses of GPOA% showed significant differences at 2- and 3-mm levels. The strong tug-back with sGPOA of 76.5 ± 11.1% was significantly higher than that of slight tug-back. Conclusions: Under the conditions of this study, the tug-back scoring system can be applied to determine the amount of GP adaptation inside the root canal. Strong tug-back sensation showed the highest GP adaptation although at least one-fifth of the apical canal region was left unfilled.

September-December 2016, 6(3):113-121
DOI:10.4103/1658-5984.189350  
Introduction: The aims of this study were to (1) investigate the root and root canal morphology of human third molars in a Jordanian subpopulation and (2) determine the effect of age, gender, and tooth location on the morphology of these teeth. Materials and Methods: A total of 159 maxillary and mandibular third molars were used in this study. After canal staining and tooth clearing, the specimens were examined, and the following morphological features were recorded: Number of roots and presence of roots fusion, number of canals and their configurations in each root, total number of canals per tooth, and incidence of lateral canals and intercanal communications. Results: The majority (74.2%) of maxillary molars had 3 roots and 3 (55.1%) or 4 (27%) canals while the majority (74.3%) of mandibular molars had 2 roots and 2 (38.6%) or 3 (45.7%) canals. Roots fusion was found in 70.1% of maxillary molars and 40.7% of mandibular molars. Type I canal configuration was the predominant type in distal roots of mandibular molars and distobuccal and palatal roots of maxillary molars. Multiple canals were evident in 36% of the maxillary mesiobuccal roots and 56% of mandibular mesial roots. Single/fused roots showed a wide range of canals number and configurations. The number of roots and canals in both molars did not differ with gender, age, and tooth location. Females had a higher incidence of roots fusion than males and this difference was significant in mandibular molars (P = 0.034). Conclusions: Third molars showed a range of root and canal morphologies. Careful preoperative assessment is essential before commencing root canal treatment on these teeth.

DOI:10.4103/1658-5984.138136  
Objectives: This study was done to evaluate the flexural strength of carbon, quartz, and glass fiber posts by means of three-point bending test. Materials and Methods: Thirty pre-fabricated fiber posts were used and divided into three groups. Group I carbon fiber posts (C-Post), group II quartz fiber post (Aestheti Plus), group III glass fiber post (Para Post White) Ten posts (N = 10) were used for each experimental group and were measured with digital caliper before test accomplishment. The fracture load of post specimens was measured, and flexural strength was obtained by the formula using S = 8FL/pd 3 . The values in Kgf/mm 2 were obtained and calculated to Mpa and submitted to ANOVA (a = 0.01) and to the Tukey's test. Results: The mean values of flexural strength show that group II quartz fiber posts (666 MPa) are significantly higher than group I carbon fiber (614 MPa) and group III glass fiber (575 MPa). C onclusion: Hence, this study concluded that quartz fiber post showed significantly higher flexural strength values. Further scope of this study lies in the evaluation and evolution of a restorative materials used for post and core preparation, which have modulus of elasticity in harmony with that of dentin and near-natural esthetic appearance.

New vistas in endodontic diagnosis
Shashi Prabha Tyagi, Dakshita Joy Sinha, Radhika Verma, Udai Pratap Singh
May-August 2012, 2(2):85-90
DOI:10.4103/1658-5984.108158  
In the recent times no other field has shown so much growth in Endodontics as much as that of diagnosis. The human element in diagnosis is enriched by newer technologies available as adjuncts to the process of endodontic diagnosis. The trend of this development has been toward increasing objectivity sensitivity and reproducibility of the pulp tests while decreasing the patient discomfort. Methods like Pulse Oximetry, Laser Doppler Flowmetry, Ultrasound Doppler, Dual Wavelength Spectroscopy, Photoplethysmography besides the thermographic imaging and calorimetric pulp tests are being developed and evolved to suit the current clinical setting for the modern endodontist. A necessity arises here to keep abreast of all the new methods in order to be able to choose the best tools for the successful diagnostician. The aim of this review therefore was to assess the usefulness of some devices and techniques used in endodontic therapy to make the correct pulpal diagnosis.

DOI:10.4103/1658-5984.138141  
Introduction: Endodontic infections are polymicrobial in nature. Enterococcus fecalis is the most common micro-organism isolated from failed endodontic cases. The constant increase in antibiotic resistant strains and side effects caused by synthetic drugs has prompted researchers to look for herbal alternatives since the gold standard for irrigation i.e., sodium hypochlorite (NaOCl) has many disadvantages. Objective: The present study was aimed to explore newer irrigation solutions, which would probably be as effective as NaOCl. Materials and Methods: Extracted human single rooted premolar teeth were biomechanically prepared, vertically sectioned, placed in tissue culture wells exposing the root canal surface to E. fecalis is grown on Mueller Hinton agar plates to form a biofilm for 6 weeks. At the end of 6 th week, all seven groups were treated with 3 ml of test solutions and control for 10 minutes and evaluated for E. fecalis growth and number of colony forming units. Results: Propolis, NaOCl and triphala showed no statistically significant difference, whereas all the other inter-group differences were statistically significant (Tukey's honest significant difference (HSD)) (P < 0.001). Conclusion: Propolis and triphala were found to be as efficacious as NaOCl. The use of herbal alternatives as root canal irrigation solutions might prove to be advantageous considering several unfavorable properties of NaOCl.

DOI:10.4103/1658-5984.127980  
Background : Dentin hypersensitivity is a commonly experienced problem that is triggered by an external stimulus, such as hot and cold temperature changes, pressure from tooth brushing and osmotic changes caused due to sweet or sour food and beverages. Various treatment modalities are tried and tested, amongst them desensitizing pastes have been used extensively in the past decades. Objective: The objective of these 15 days, single center, randomized clinical pilot study was to evaluate the dentin hypersensitivity reducing efficacy of two commercially available desensitizing toothpastes: One with Pro-Argin technology and the other with Novamin. Materials and Methods: Eighty subjects of dentin hypersensitivity were sampled in the present pilot study. Subjects were randomly selected and the pastes were prescribed for both the groups. Subjects were advised to brush twice daily for 2 min with the desensitizing paste and also were advised for topical application of the desensitizing paste on sensitive teeth and were asked not to rinse until morning. The evaluation was done by Air blast technique using sensitivity visual analog scale consisting of mild, moderate, and severe parameters rated on a scale of 0-10. Efficacy was compared on baseline, after 1 min of application and after 15 days. Statistical Analysis: t-test was performed and P value ≤ 0.05 was considered as statistically significant. Results: There was no statistically significant difference between the two groups after 1 min of examination, but there was a statistically significant difference in reduction of dentin hypersensitivity after 15 days interval favoring Vantej group (P ≤ 0.02). Conclusion: Desensitizing paste containing 5% NovaMin crystals provided a statistically significant reduction at 15 days interval when compared with the one containing Pro-Arginine.

DOI:10.4103/1658-5984.149081  
Teeth with calcification provide an endodontic treatment challenge; traumatized teeth usually develop partial or total pulpal obliteration which is characterized by apparent loss of the pulp space radiographically and a yellow discoloration of the clinical crown. Since only 7-27% of such teeth develop pulp necrosis with radiographic signs of apical periodontitis, it is difficult to decide whether to treat these teeth immediately upon detection of the pulpal obliteration or to wait until signs and symptoms of pulp and/or apical periodontitis occur. This article reviews the etiology, prevalence, classification, mechanism, diagnosis as well as treatment options for teeth with pulp obliteration and the various management approaches and treatment strategies for overcoming potential complications. A search of articles from "PubMed" and "Medline" from 1965 to present was done with the keywords dental trauma, discoloration, pathfinding instruments, pulp canal obliteration, and root canal treatment was conducted. A total of 94 abstracts were collected, of which 70 relevant articles were read and 31 most relevant articles were included in this article.

Materials and Methods: Eighty extracted human mandibular incisors were collected from Saudi patients. The teeth were accessed by small round bur then placed in 5.25% sodium hypochlorite for 24 hours to dissolve the organic debris. Indian ink was injected inside the root canal systems under negative pressure. The teeth were decalcified in 5% nitric acid for three days then dehydrated in different concentrations of ethyl alcohol. Following the decalcification process, the teeth were cleared in methyl salicylate and evaluated according to Vertucci's classification. Result: Fifty six of both mandibular central and lateral incisor teeth (70%) had type I canal configuration (one main canal and one main apical foramen), while the remaining 30% of the sample (24 teeth) had a type III canal configuration (two separate canals and merged into one canal before exiting the tooth through single apical foramen). Conclusion : The incidence of two canals in mandibular incisor teeth is about one third of the examined Saudi Arabian samples with no difference between the centrals and laterals. The clinician should deal with these teeth as if they have two canals unless it is proved otherwise.
