Healing of a large periapical lesion using triple antibiotic paste and intracanal aspiration in nonsurgical endodontic retreatment
Jaidev Singh Dhillon, Amita , Suresh Kumar Saini, Harmandeep Singh Bedi, Sukhmilap Singh Ratol, Bobbin Gill
July-September 2014, 5(3):161-165
A patient with a large periapical lesion in relation to the maxillary right central and lateral incisors is presented here. During the conservative root canal treatment, aspiration of the fluid was done through the root canal, followed by placement of triple antibiotic paste for two weeks. Complete periapical healing was observed at the 24-month recall. This report confirms that for treatment of a large periapical lesion it is not always necessary to do surgical treatment and even cyst-like periapical lesions heal following conservative endodontic therapy.

Ramesh Ram Fry, Dinesh Chand Patidar, Samta Goyal, Aayush Malhotra
July-September 2016, 7(3):126-130
DOI:10.4103/0975-962X.189339  PMID:27795646
Aim: The study aimed to investigate the proximity of maxillary posterior teeth roots to maxillary sinus and measure the distance of maxillary posterior teeth roots and the sinus floor as well as the thickness of bone between the roots and alveolar cortical bone using Denta scan®. Materials and Methods: The study samples include Denta scan® images of fifty patients with normally erupted bilateral maxillary first premolar to maxillary second molar. The vertical relationship of each tooth root with maxillary sinus is classified into four types of Denta scan® images (based on the classification by Jung in 2009). The distance between the sinus floor and root, and the bone thickness between the root and alveolar cortical plate will be measured and analyzed. Conclusion: The buccal root of the maxillary molars was more commonly protruded into the maxillary sinus. Among the roots of maxillary posterior teeth, mesiobuccal root of first molar and palatal root of second premolar were found in close proximity to the floor of maxillary sinus. The bone thickness on the buccal aspect to the root was significantly thinner in the maxillary first premolar and maxillary first molar as compared to other maxillary posterior teeth roots. Clinical Significance: Knowledge of anatomical relationship between the maxillary posterior teeth and maxillary sinus guides us not only in proper preoperative treatment planning but also avoids the possible complications encounter while performing the minor oral surgical procedures involving maxillary posterior teeth, which are close to the maxillary sinus.

Prosthodontic rehabilitation of patient with flabby ridges with different impression techniques
Rubina Bansal, Manjit Kumar, Rashim Garg, Rishi Saini, Shaveta Kaushala
April-June 2014, 5(2):110-113
A fibrous or flabby ridge is a superficial area of mobile soft tissue affecting the maxillary or mandibular alveolar ridges. It can develop when hyperplastic soft tissue replaces the alveolar bone and is a common finding particularly in the upper anterior region of long term denture wearers. Masticatory forces can displace this mobile denture-bearing tissue, leading to altered denture positioning and loss of peripheral seal. Forces exerted during the act of impression making can result in distortion of the mobile tissue. Unless managed appropriately by special impression techniques, such 'flabby ridges' adversely affect the support, retention and stability of complete dentures. This paper presents three case reports for prosthodontic rehabilitation of patient with flabby ridges with three different impression techniques.

Satishkumar G Patil, Bindu S Patil, Udupikrishna Joshi, Soumya Allurkar, Sharanabasappa Japatti, Ashwini Munnangi
July-September 2016, 7(3):116-120
DOI:10.4103/0975-962X.180318  PMID:27795644
Background: With the development of urban setting worldwide, the major issue of concern is the increase in the mortality rate in the population due to road traffic accidents. The face, being the most exposed region is susceptible to injuries and maybe associated with injuries to the adjacent neuro-cranium. The literature has conflicting views on the relationship between facial fractures and head injuries with some authors opining that the facial skeleton cushions the brain while some other authors claim that the facial fractures act as indicators for head injuries. Objectives: To analyze the correlation between the facial fractures and head injuries and to assess if the facial skeleton acts to protect the brain from injury. Patients and Methods: A prospective study that included patients who reported to the emergency department of Basaveswar Teaching and General Hospital, Gulbarga, during 2 years, between August 2013 and July 2015 was conducted. A total of 100 patients with facial fractures were enrolled in the study. Results: Head injuries were sustained by 51 patients in the study. Maximum number of patients was in the age group of 20–29 with a male to female ratio of 10.1:1. The mandible was the most frequently fractured bone in the facial skeleton followed by the zygomatico-maxillary complex. A majority (96%) of patients with head injuries had fractures of either the upper third or the middle third of the face. Contusions and pneumocephalus were the most common head injury encountered. The Glasgow Coma Scale score was significantly lower in patients with associated head injuries as compared to those patients with facial trauma alone. The mortality rate in the study was 2% with both the victims having sustained middle third and upper third fractures respectively with associated head injuries. Conclusion: The facial skeleton does not act to cushion the brain from injury but, in fact, the facial trauma victims should be considered potential head injury patients.

Parimala Kulkarni, Ayushi Anand, Arpana Bansal, Ankur Jain, Utkarsh Tiwari, Suchi Agrawal
July-September 2016, 7(3):131-133
DOI:10.4103/0975-962X.189338  PMID:27795647
Context: The use of liquid medicinal syrups in childhood is high owing to the reasons that children suffer from illness quite often. The acidic component in the formulations may cause erosion to the dental tissues. Aims: The aim of this study is to evaluate the erosive potential of pediatric liquid medicinal syrups on the deciduous teeth. Subjects and Methods: A total of sixty extracted/exfoliated noncarious deciduous molars were used. Four medical syrups were used (viz., 1 - artificial saliva [control], 2 - Ferium XT, 3 - Crocin syrup, 4 - Ambrolite-D) and the teeth were equally divided into the four groups (n = 15) for the immersion cycle, following which the teeth were examined for surface microhardness at 7, 14, 21, and 28 days. Statistical Analysis Used: ANOVA and post hoc analysis were applied. Results: The time and immersion media interaction demonstrated that antitussives produced a significant and gradual loss of surface microhardness on all days (viz., 7, 14, 21, and 28 days), but a statistically significant difference was seen only between 7th and 28th day (P < 0.05). Conclusions: The knowledge of the erosive potential of commonly used syrups is mandatory as erosion in children teeth may be associated with dental hypersensitivity, loss of the occlusal vertical dimension, eating difficulties, poor esthetics, pulp exposure, and abscesses. Mouth rinsing with water after taking the medication; addition of calcium, fluoride, or phosphate to formulations; and consumption of the medication at meal times have been recommended to avoid tooth damage that is caused by the regular use of medication.

Comparison of gonial angle determination from cephalograms and orthopantomogram
Mandeep Kaur Bhullar, Amandeep Singh Uppal, Gulsheen Kaur Kochhar, Sanjay Chachra, Anuraj Singh Kochhar
July-September 2014, 5(3):123-126
Introduction: Gonial angle is an important parameter of the craniofacial complex giving an indication about the vertical parameters and symmetry of the facial skeleton. Both orthopantomogram (OPG) and lateral cephalograms can be used for the measurement of gonial angle. Because of the superimpositions seen on lateral cephalograms, reliable measurement of the gonial angle becomes difficult. The aim of the present study is to check the possible application and reliability of OPG for gonial angle determination by clarifying whether there is any significant difference between the determination of gonial angle from OPG and cephalogram. Materials and Methods: Gonial angle measurements were made on lateral cephalograms and orthopantomograms of 98 patients - 44 males (mean age 25.9 years) and 54 females (mean age 21.3 years), and compared using Statistical Package for Social Sciences. Results: One-way analysis of variance demonstrated no significant differences between the values of gonial angles determined by lateral cephalogram and panoramic radiography. Pearson correlation showed a high correlation between cephalometric and OPG gonial angle value. Conclusion: Panoramic radiography can be used to determine the gonial angle as accurately as a lateral cephalogram. For determination of the gonial angle, an OPG may be a better choice than a lateral cephalogram as there are no interferences due to superimposed images of anatomical structures as in a lateral cephalogram. Thus, the present study substantiates the possibility of enhancing the clinical versatility of the panoramic radiograph, which is an indispensable tool for dental diagnosis.

Background: There is a paucity of information about the relationship of forensic odontology with various dental specialties in the articles published in the Journal of Forensic Odonto-Stomatology. This study aimed to find the relationship of forensic odontology with various dental specialties in the articles published in the Journal of Forensic Odonto-Stomatology from 2005 to 2012 over an 8-year period. Methods: Bibliometric analysis was performed using web-based search during December 2013. Results: Out of the total 97 published articles, the maximum number of published articles were related to oral medicine and radiology (20) and community dentistry (20), followed by orthodontics (18), prosthodontics (15), and oral pathology and microbiology (8), pedodontics (7), oral and maxillofacial surgery (4) and conservative dentistry and endodontics (3). Among the articles published in Journal of Forensic Odonto-Stomatology, mass disasters (10) and bite mark analysis (10), followed by sexual dimorphism (8) and dental fraud and malpractice (8), followed by craniofacial superimposition (6) and identification (6) form the major attraction of the contributors. Conclusion: This paper has tried to evaluate the new working classification proposed for forensic odontology based on its relationship with other dental specialties.

Curve of Spee - from orthodontic perspective
Sushma Dhiman
October-December 2015, 6(4):199-202
DOI:10.4103/0975-962X.170392  PMID:26752075
The presence of a curve of Spee (COS) of variable depth is common finding in the occlusal arrangement and is sixth key of occlusion The understanding of COS in the field of orthodontics is very important as orthodontists deal with it in virtually every patient they treat. An excessive COS is a common form of malocclusion that may be addressed in many ways, including posterior extrusion, anterior intrusion, and incisor proclination. The specific approach to leveling of COS should be selected based on each patient's needs. Soft tissue, crown–gingival relations, occlusal plane, and skeletofacial concerns are among the special considerations for treatment planning for leveling of COS.

Prashant Babaji, Vikram Singh, Vishwajit Rampratap Chaurasia, Vinaykumar S Masamatti, Akanksha Manmohan Sharma
October-December 2014, 5(4):211-213
Oral squamous papillomas are benign proliferating lesions induced by human papilloma virus. These lesions are painless and slowly growing masses. As an oral lesion, it raises concern because of its clinical appearance. These lesions commonly occur between age 30 and 50 years, and sometimes can occur before the age of 10 years. Oral squamous papilloma accounts for 8% of all oral tumors in children. Common site predilection for the lesion is the tongue and soft palate, and may occur on any other surface of the oral cavity such as the uvula and vermilion of the lip. Here, we are presenting a case of squamous papilloma on the palate.

Yuvika Mittal, Govind Jindal, Sandeep Garg
April-June 2016, 7(2):86-94
DOI:10.4103/0975-962X.184650  PMID:27433052
The use of dental implants for the rehabilitation of missing teeth has broadened the treatment options for patients and clinicians equally. As a result of advances in research in implant design, materials, and techniques, the use of dental implants has increased dramatically in the past two decades and is expected to expand further in the future. Success of dental implants depends largely on the quality and quantity of the available bone in the recipient site. This however may be compromised or unavailable due to tumor, trauma, periodontal disease, etc., which in turn necessitates the need for additional bone manipulation. This review outlines the various bone manipulation techniques that are used to achieve a predictable long-term success of dental implants.

DOI:10.4103/0975-962X.155877  PMID:26097339
Human papillomaviruses (HPVs) are epitheliotropic viruses with an affinity for keratinocytes and are principally found in the anogenital tract, urethra, skin, larynx, tracheobronchial and oral mucosa. On the basis of high, but variable frequency of HPV in oral squamous cell carcinoma (OSCC), malignant potential of HPV infection has been hypothesized but not definitely confirmed. The aim of this review was to highlight the genomic structure and possible mechanism of infection and carcinogenesis by HPV in the oral mucosa and to review the frequency of HPV prevalence in OSCC and oral potentially malignant disorders. A computer database search was performed through the use of PubMed from 1994 to 2014. Search keywords used were: HPV and oral cancer, HPV and oral leukoplakia, HPV and oral lichen planus, HPV and OSCC, HPV and verrucous carcinoma, HPV and proliferative verrucous leukoplakia, HPV and oral papilloma.

Tanuj Kanchan, Meghna Machado, Ashwin Rao, Kewal Krishan, Arun K Garg
April-June 2015, 6(2):99-102
DOI:10.4103/0975-962X.155887  PMID:26097340
Identification of individuals is the mainstay of any forensic investigation especially in cases of mass disasters when mutilated remains are brought for examination. Dental examination helps in establishing the identity of an individual and thus, has played a vital role in forensic investigation process since long. In this regard, description on the role of enamel hypoplasia is limited in the literature. The present article reviews the literature on the enamel hypoplasia and discusses its utility in forensic identification. Enamel hypoplasia is a surface defect of the tooth crown caused by disturbance of enamel matrix secretion. Enamel defects can be congenital or acquired. In cases of mass disasters, or when the body is completely charred, putrefied and mutilated beyond recognition, the unique dental features can help in identification of the victims.

DOI:10.4103/0975-962X.151697  PMID:25767356
Background: The aim of the study was to compare the efficacy of chlorhexidine gluconate 2.5 mg (Periochip) and Minocycline hydrochloride 1 mg (Arestin) as local drug delivery agents in the management of chronic periodontitis. Materials and Methods: Twenty patients in the age group of 30-50 years suffering from chronic periodontitis (12 males and 8 females), with almost identical probing depth bilaterally (5-8 mm), and exhibiting bleeding on probing were selected and divided into two groups: Group I consisted of periodontal pockets on the left side and received Periochip and group II consisted of periodontal pockets on the right side and received Arestin. Patients were recalled after 6 weeks and 3 months intervals from the baseline visit to record plaque index, gingival index, and probing depth. Results: There was reduction in all the parameters in both the groups at 6 weeks and 3 months as compared to baseline. Conclusion: From the results of the present study, it was concluded that both the drugs were equally effective in reduction of plaque scores as well as gingival scores. It was further observed that Arestin resulted in better results at 6 weeks while Periochip showed better results at 3 months with respect to probing depth reduction.

Shantala Arunkumar, Anupama N Kalappanavar, Rajeshwari G Annigeri, Shakuntala G Kalappa
January-March 2015, 6(1):14-19
DOI:10.4103/0975-962X.151692  PMID:25767355
Background and Objectives: Oral lichen planus (OLP) is a relatively common, chronic inflammatory condition that frequently presents with symptoms of pain and burning sensation. It is generally a very unrelenting disorder despite several kinds of treatment. Only symptomatic OLP requires treatment, and it remains a challenging predicament. Efforts are made in a sustained manner for searching for novel therapies for symptomatic OLP. Therefore, this study was aimed to compare the efficacy of treatment with topical pimecrolimus cream 1% with that of triamcinolone acetonide oral paste 0.1% in subjects with symptomatic OLP. Materials and Methods: A prospective, parallel-group, randomized, active control clinical study was conducted among 30 symptomatic OLP subjects (20 females and 10 males, with 15 patients in each treatment group) treated with topical pimecrolimus 1% cream and triamcinolone acetonide 0.1% oral paste four times daily for two consecutive months and treatment-free follow-up was performed for 2 months. Pain or burning sensation, mean clinical score and presence of erythematous areas were assessed. The data obtained were statistically analyzed using Wilcoxon's Rank test and the Mann Whitney test. Results: Subjects in both the groups showed significant improvement in symptom scores; however, the overall treatment response was higher in the pimecrolimus group compared with the triamcinolone acetonide group. On intergroup comparison, there was no statistically significant difference between the groups in the reduction in burning sensation (P = 0.18) and erythematous area (P = 0.07), but there was a statistically highly significant improvement in reduction of clinical scoring (P < 0.01%). Following the termination of the treatment, sustained remission of symptoms and long-lasting therapeutic effects was detected in 93.3% of the patients treated with pimecrolimus. Interpretation and Conclusion: Topical pimecrolimus 1% cream showed better therapeutic response compared with triamcinolone acetonide 0.1% oral paste in subjects with symptomatic OLP.

Vandana Gadve, Apurva Mohite, Kshitij Bang, SR Shenoi
July-September 2016, 7(3):162-164
DOI:10.4103/0975-962X.174594  PMID:27795655
Salivary gland calculi account for the most common disease of the salivary glands. Most of the salivary calculi are small in size. Some calculi that reach several centimeters are reported as megaliths or giant calculi in the literature. They may occur in any of the salivary gland ducts but are most common in Wharton's duct and in the submandibular gland. This report presents clinical and radiographical sign of an unusually large sialolith. A patient came with pain in the floor of mouth. There was a swelling on floor of mouth on the left side. Radiographical examination revealed large irregular radio-opaque mass superimposed on left lateral incisor to molar areas. This case report describes a patient presenting with an unusually large submandibular gland duct sialolith, the subsequent patient management, the etiology, diagnosis, and its treatment.

Serum vitamin c and iron levels in oral submucous fibrosis
R Guruprasad, Preeti P Nair, Manika Singh, Manishi Singh, MP Singh, Arpit Jain
April-June 2014, 5(2):81-85
Background: In this study Serum Vitamin C and Iron levels in Oral submucous fibrosis (OSMF) were estimated. The objective was to evaluate the correlation between Serum Vitamin C and Iron levels in OSMF individuals. Serum Iron content can be a predictor for the progression of this condition. OSMF is basically a disorder of collagen metabolism where Vitamin C gets utilized in conversion of proline into hydroxyproline, this hydroxylation reaction requires ferrous Iron and Vitamin C. Many studies regarding micronutrients and other antioxidants levels have been emphasized, but very few studies are done on the Serum levels of Vitamin C and its correlation with Iron in OSMF patients. Methods: Thirty five OSMF patients and 50 deleterious habit free healthy individuals (controls) were selected. Two ml of venous blood was collected from each individual. Vitamin C level in serum was estimated by 2-4 dinitrophenylhydrazine method and Iron estimated by Tripyridyl method. Results: The level of Serum Vitamin-C and Iron was significantly decreased in OSMF patients when compared to controls which were statistically significant. Conclusion : On the basis of these observations, it seems possible that the chemical, thermal and/or mechanical factors associated with the use of areca nut may act in conjunction with the Vitamin C and Iron deficiency leading to the development of OSMF. Therapeutic substitution of vitamin C and Iron may be recommended in the management of OSMF

DOI:10.4103/0975-962X.168518  PMID:26752875
Aims: The aim of the study was to assess the awareness of the patients regarding implant-retained prosthesis as an option for tooth replacement and the knowledge about tooth replacement as a whole including source of information and attitude towards it amongst Malaysian population. \Materials and Methods: Information on demographic characteristics, knowledge about implant as an option for missing tooth replacement, source of information and knowledge about other options of tooth replacement were obtained from patients visiting various dental outpatient departments of hospital and private dental clinics using nationwide self-explanatory survey. Results: Amongst the 1013 response retrieved, 27% of respondents felt moderately well informed about the dental implant treatment. Only 9% of the respondents had dental implant treatment before and 17% felt well informed about different alternatives of replacing missing teeth. The dentists were the main source of information regarding dental implant treatment modality followed by friends and electronic media. 55.6% respondents felt implant to be as good as own teeth during function whereas high cost was the major limiting factor for implant treatment. Conclusion: 56% of Malaysian population was aware of dental implant as an alternative for replacing missing teeth. Necessary efforts and measures should be made to raise the awareness of dental implant treatment in the country.

Oral cancer appears to be increasing in incidence, and mortality has hardly improved over the past 25 years. Better understanding of the etiopathogenesis should lead to more accurate and earlier diagnosis and more effective treatments with fewer adverse effects. Despite increasing interest in the possible relationships between bacteria and the different stages of cancer development, the association of bacteria with cancer of the oral cavity has yet to be adequately examined. Different bacteria have been proposed to induce carcinogenesis, either through induction of chronic inflammation or by interference, either directly or indirectly, with eukaryotic cell cycle and signaling pathways or by metabolism of potentially carcinogenic substances like acetaldehyde, causing mutagenesis. This review presents the possible carcinogenesis pathway involved in bacterial carcinogenesis, commonly implicated bacteria in oral carcinogenesis and their role in cancer therapeutics as well.

A case of Robinow-Sorauf syndrome (Craniosynostosis-Bifid Hallux Syndrome): The allelic variant of the Saethre-Chotzen syndrome
Arpita Rai Thakur, Venkatesh G Naikmasur
April-June 2014, 5(2):96-99
The clinical classification of Robinow-Sorauf syndrome has changed over the last few decades. Robinow-Sorauf syndrome is characterized by facies similar to those of Saethre-Chotzen syndrome with bifid or partially duplicated halluces. The current outlook is that the 'Robinow-Sorauf' families are examples of variable expression of the TWIST mutant phenotype and that the 'Robinow-Sorauf' syndrome lies within the spectrum of the Saethre-Chotzen syndrome. We present a case of 19-year-old female patient exhibiting classical clinical and radiological features of Robinow-Sorauf phenotype of Saethre-Chotzen syndrome. A brief review of previously reported cases and nosology has been presented.

Simrat Kaur, Kusum Datta, SK Gupta, Neelam Suman
January-March 2016, 7(1):1-5
DOI:10.4103/0975-962X.179380  PMID:27134447
Aims and Objectives: The purpose of the study was to determine the effect of border molding on the retention of the maxillary denture base. Materials and Methods: Two special trays, one with full extensions to the periphery and one 2 mm short from the borders were made on the cast obtained from the preliminary impression. Border molding was done on the tray which was short from borders. On both trays, the final impression was made with zinc oxide eugenol impression paste. Heat cure denture bases were fabricated on the prepared casts and retention was measured using specially designed instrument. Observations and Results: Mean force with border molding (2765.0 g) was larger than mean force without border molding (1805.0 g) at P < 0.01 level. In terms of percentage, too, the mean improvement (59.4%) in force of dislodgement was statistically highly significant (i.e. P < 0.01). Clinical Significance: The results of the present study suggest that the dentures made with border molding will provide better retentive force than the dentures made without border molding.

For full-thickness lip defects, the choice of reconstructive option depends on the size of the defect. Defects of one-quarter to one-third of the upper lip can be closed primarily. Largerdefects measuring one-third to two-thirds of the lower lip width may be closed with the Karapandzic, Abbe or Estlander flaps. If the commissure is involved, both the Karapandzic and Estlander flaps may be used; however, the Karapandzic is probably the better choice because it is better at maintaining oral competence. In the case of larger lower lip defects (more than two-thirds of the lip), if there is sufficient adjacent cheek tissue, the surgeon may employ the Karapandzic (for defects up to three-fourths of the lower lip width) or the Bernard-Burow's techniques (to reconstruct the entire lower lip). A case of post-traumatic, lower lip defect, reconstructed with a bilateral karapandzic flap is presented here.
