DOI:10.4103/0970-9290.135906  PMID:24992842
Background: Dental caries is a major chronic noncommunicable disease affecting whole of mankind. Nontreatment of caries can have severe consequences such as pain, abscess formation, space infection, etc., which leads to loss of function, working hours or absence from school in children. These consequences are equally important, while planning dental care program for a community. Aim: The aim of this study is to assess the prevalence and severity of consequences of untreated carious lesions using pufa index that is, pulpal involvement, and ulcer due to root fragments, fistula, and abscess index among 5-6 year old school children in an urban Indian population. Materials and Methods: A cross-sectional survey was conducted on 603 school going children of 5-6 year age group in mainly an urban Indian population. Children from 12 randomly selected schools were examined for pufa and decayed extracted filled indices. Results and Conclusions: Overall mean pufa value was 0.9 ± 1.93 and prevalence was 38.6% with major contribution from P component of index. Untreated caries ratio was 35%, suggesting that more than one-third of the developed carious lesions cause adverse events in a population. This study emphasis the need for treating dental caries at its earliest possible stage to avoid severe consequences. The pufa index can be used as tool to highlight these adverse consequences to dental professionals and health authorities.

Aims: The aim of this research was to complete Habets's method on orthopantomogram, in order to measure mandibular symmetry horizontally and diagonally in mixed dentition as the first diagnostic evaluation. Settings and Design: Mixed dentition subjects were consecutively selected according to skeletal maturity. Materials and Methods: Inclusion criteria were: Mixed dentition, cervical vertebral stages 1-2, Class II or Class III malocclusions, with or without unilateral posterior cross-bite. Fourteen subjects with cross-bite (mean age 8 y, 9 m) cross group (CG) and 14 subjects with normal transverse occlusion (mean age 8y, 6m) non-cross group (NCG) were selected. Nine measurements were determined. An asymmetry index was performed for all linear variables. Statistical Analysis Used: NCG patients' data were compared with CG data using parametric t-tests. Probabilities of <0.05 were accepted as significant. Results: In CG, comparing right and left side, single values showed no significant differences up to 6% (twice if compared to the 3% threshold value). T-tests showed statistically significant differences between the groups for ramus + condyle height (index 2.5% vs 4.5%, P = 0.04), condylar height (index 3.7% vs 6.6%, P = 0.02) and mandibular length (index 1.4% vs 2.3%, P = 0.04). Overall CG group was more asymmetrical than NCG. Conclusions: In mixed dentition (CS1-2), a first appraisal of mandibular symmetry may be performed on orthopantomogram utilizing this modified Habets's method. This tracing method provides an early evaluation about mandibular symmetry and is able to show slight asymmetries in mixed dentition thereby reducing the number of cone beam computed tomograms performed.

DOI:10.4103/0970-9290.135929  PMID:24992856
Nasolabial cyst, also known as Klestadt's cyst is an uncommon nonodontogenic cyst. Bilateral nasolabial cysts are rarer and less than 10 cases have been reported in the literature. Diagnosis is usually clinical and they present as slow-growing swellings in the nasolabial region causing cosmetic deformity and nasal obstruction. A postpartum lady presented with bilateral swelling of the cheeks. Excision was done via a sublabial approach. She is asymptomatic one year after surgery. Nasolabial cysts are developmental but usually noticed after a trauma. There is no data relating the cysts to pregnancy.

Regenerative endodontics is the creation and delivery of tissues to replace diseased, missing, and traumatized pulp. A call for a paradigm shift and new protocol for the clinical management of these cases has been brought to attention. These regenerative endodontic techniques will possibly involve some combination of disinfection or debridement of infected root canal systems with apical enlargement to permit revascularization and use of stem cells, scaffolds, and growth factors. Mesenchymal stem cells (MSCs) have been isolated from the pulp tissue of permanent teeth (dental pulp stem cells (DPSCs)) and deciduous teeth (stem cells from human exfoliated deciduous teeth). Stem cells are characterized as multipotent cells for regeneration.These three case reports describe the treatment of necrotic or immature teeth with periradicular periodontitis, which was not treated with conventional apexification techniques. All cases presented here developed mature apices and bone healing after 3 to 4 months after the initial treatment without complications, and faster than traditional treatments. Our clinical observations support a shifting paradigm toward a biologic approach by providing a favorable environment for tissue regeneration. The mechanism of this continued development and formation of the root end and faster tissue healing is discussed.

Langerhans cell histiocytosis (LCH) is a rare idiopathic disease characterized by the clonal proliferation of Langerhans cells. LCH affects five children per million population. The peak incidence is from 1 to 4 years of age. LCH involves the head and neck region quite commonly. Oral soft tissue lesions are also common. The differential diagnosis of oral LCH includes leukemia, neutropenia, prepubertal periodontitis, hypophosphatasia, fibrous dysplasia, and Papillon-Lefevre syndrome. The prognosis of LCH depends on early detection and appropriate management. Surgical management alone is used in 50% of cases with an additional 23% of the lesions being treated with both surgery and radiation therapy. A case of LCH in a 6-year-old girl involving the mid root level of developing first permanent molar with a floating developing tooth bud of permanent second molar mimicking an inflammation is reported.

DOI:10.4103/0970-9290.135931  PMID:24992858
Background: Some endodontic procedures may cause damage to the inferior alveolar nerve, leading to paraesthesia. When such complication is due to extrusion of obturation material beyond the apex, it can be managed by intentional replantation (IR). IR consists of the removal of a tooth and its re-insertion into the socket after performing a proper root end manipulation. It is a relatively conservative procedure aimed at preserving the tooth and, with correct case selection, can provide a predictable outcome. Aims: The aim of the present paper is to report a case of paraesthesia following endodontic treatment of second mandibular molar successfully treated by intentional replantation. Results and Conclusion: In our opinion this treatment modality may be considered when the extrusion of root canal filling material causes irritation to the periapical tissues and endodontic retreatment is unfeasible.

Filariasis affecting animals can rarely cause infections in human beings through the accidental bite of potential vectors. The resulting infection in man, known as zoonotic filariasis occur worldwide. Human dirofilariasis, the most common zoonotic filariasis, is caused by the filarial worm belonging to the genus Dirofilaria. Dirofilarial worms, which are recognized as pathogenic in man can cause nodular lesions in the lung, subcutaneous tissue, peritoneal cavity or eyes. Oral dirofilariasis is extremely rare and only a few cases have been documented. We report an interesting case of dirofilariasis due to Dirofilaria repens involving buccal mucosa in a patient who presented with a facial swelling. The clinical features, diagnostic issues and treatment aspects are discussed. This paper stresses the importance of considering dirofilariasis as differential diagnosis for subcutaneous swelling of the face, especially in areas where it is endemic.

DOI:10.4103/0970-9290.135919  PMID:24992850
Context: Salivary control and maintenance of a dry operating field is a prime requisite of orthodontic bonding. Moisture insensitive primer (MIP) with a clinical significant bond strength values have a better edge over the conventional hydrophobic bonding systems. Aim: The aim of this study is to investigate the effectiveness of two hydrophilic primers with respect to conventional hydrophobic primer by comparing their shear bond strength (SBS) and adhesive-failure locations after contamination with saliva and saliva substitute. Materials and Methods: A total of 150 extracted human premolars were randomly divided into five group s ; Group A (Transbond MIP/saliva substitute), Group B (Opal Primo/saliva substitute), Group C (Transbond MIP/natural saliva), Group D (Opal Primo/natural saliva), control group - Group E (Transbond XT/dry), adhesive-Transbond XT used for all five groups and bonded using stainless steel brackets. Shear forces were applied to the samples with a universal testing machine. SBSs was measured in megapascals. The mode of bond failure was determined using the adhesive remnant index (ARI). Results: The mean SBS produced by Transbond MIP was higher than Opal Primo, which was statistically significant according to one-way analysis of variance. Both the tested groups showed lesser bond strength values than Transbond XT (the control). ARI scores revealed that there was no statistically significant difference in the site of bond failure between study groups. ARI scores were found to be lower for study groups suggesting adhesive failure, compared to higher ARI scores for the control group suggesting cohesive failure. Conclusion: Transbond XT adhesive with Transbond MIP or Opal Primo have clinically acceptable bond strength in wet fields. Opal Primo is a viable option to use as a hydrophilic primer clinically.

Objective: The objective of this study is to compare the putty form of bioactive glass (NovaBone Dental Putty) and particulate form (PerioGlas) in the resolution of Class II furcation defects. Background: Use of bone regeneration materials is becoming common in periodontal surgeries including furcation defects and the promising role of bioactive allograft materials has encouraged their presentation in different morphologic forms with their own advantages and disadvantages giving the operator ample of choices in his/her periodontal armamentarium. Materials and Methods: A total of 28 patients with 40 Class II furcation defects were enrolled in the study and were randomly allocated to two groups with 20 sites in each group. Measurement of defects was done using clinical and cone beam computed tomography (CBCT) methods. The patients were followed-up at 6 months. Intergroup comparisons were done using Mann-Whitney U-test. Results: There was no significance between group differences in clinical parameters and defect size at the baseline. After 6 months, particulate form showed a mean resolution of 50.48 ± 16.47% and 51.11 ± 9.48%, respectively for vertical defect and horizontal defect while putty form showed a mean resolution of 43.48 ± 9.33% and 42.88 ± 11.09%, respectively. Mean resolution in furcation width was 40.15 ± 13.00% for particulate form as compared with 36.27 ± 11.41% in putty form. Statistically, there was no significant difference between two groups except for the horizontal defect fill where PerioGlas showed statistically better results. Conclusion: Putty form was comparable to particulate form for resolution of Class II furcation defects.

Manawar Ahmad, Dhanasekar Balakrishnan, Aparna Ichangod Narayan
March-April 2014, 25(2):197-203
DOI:10.4103/0970-9290.135921  PMID:24992851
Statement of Problem: Given that meticulous implant prosthodontic procedures are recommended to obtain the best possible intraoral fit, the die systems used for multi implant casts warrant further investigation. Die stone expansion and errors introduced by removable die casts may exceed the accuracy required for the passive fit of implant prosthesis. Purpose: The purpose of the study was to evaluate the linear dimensional accuracy between the implant master die and three conceptually different die systems such as Pindex system, Accu-trac precision die system, and Conventional brass dowel pin system. Materials and Methods: Thirty impressions of implant master die were made with polyether impression material. Ten experimental implant casts were fabricated for each of the three different die systems tested: Accu-trac precision die tray system, Pindex system, and conventional brass dowel pin system. The solid experimental casts were sectioned and then removed from the die system 30 times. Linear distances between all six possible distances were measured from one centre of the transfer coping to the other, using a co-ordinate measuring machine in millimeters up to accuracy of 0.5 microns. Data were tabulated and statistically analyzed by Binomial non parametric test using SPSS version 15. Results: Significant differences were found for distance A-B (P = 0.002), A-C ( P = 0.002), A-D (P value = 0.002), and B-D ( P = 0.021) in Conventional Dowel pin system however for Accu-trac precision die tray system, it was significant only for distance A-D (P = 0.002) but for Pindex system it was non-significant for all the distances measured. Conclusion: Within the limitations of this study, use of Pindex system is recommended when sectioned dies are needed for a multi implant retained prosthesis.

March-April 2014, 25(2):174-177
DOI:10.4103/0970-9290.135913  PMID:24992846
Background: The consumption of soft-drinks has been associated with dental caries development. Objective: The aim was to evaluate dental caries experience amongst the workers working in soft-drink industries located in South India and compare it with other factory workers. To evaluate the validity of specific caries index (SCI), which is newer index for caries diagnosis. Materials and Methods: This was a cross-sectional study carried out among 420 workers (210 in soft-drinks factory and 210 in other factories), in the age group of 20-45 years of Udupi district, Karnataka, India. Index used for clinical examination was decayed, missing, filled surfaces (DMFS) index and SCI. Results: The mean and standard deviation (SD) of decayed surface (5.8 ± 1.8), missing surface (4.3 ± 2) and filled surface (1.94 ± 1.95) and total DMFS score (12.11 ± 3.8) in soft-drinks factory workers were found to be significantly higher than the other factory workers. The total SCI score (mean and SD) was found to be significantly higher in soft-drinks factory workers (5.83 ± 1.80) compared with other factory workers (4.56 ± 1.45). There was a high correlation obtained between SCI score and DMFS score. The regression equation given by DMFS = 1.178 + 1.866 (SCI scores). Conclusion: The caries experience was higher in workers working in soft-drinks factory and this study also showed that specific caries index can be used as a valid index for assessing dental caries experience.

March-April 2014, 25(2):178-183
DOI:10.4103/0970-9290.135914  PMID:24992847
Purpose: In order to assist in the selection of artificial teeth for complete dentures, this study aimed to assess the relationship between horizontal and vertical measurements of the face and the morphology of the maxillary central incisor. Materials and Methods: This was a study of 50 plaster casts and 100 teleradiographs - 50 in lateral norm and 50 in frontal norm, belonging to 50 individuals, Caucasian, with a naturally optimal occlusion, matching at least four of the six keys of Andrews. Images of the upper central incisors were obtained by scanning the plaster casts (three-dimensional) and subjectively classified by three examiners as oval, triangular or quadrangular. Facial measures (vertical and horizontal) were defined by means of teleradiographs. In order to check inter-examiner agreement on the classification of central incisor, the Kappa test was used. To verify whether data had normal distribution, the Kolmogorov-Smirnov test was used ( P > 0.2) was used. One-way analysis of variance was employed to assess the association between variables (P > 0.05). Results: When vertical measurements were compared with the three incisor shapes, there was no statistically significant difference (P > 0.05): Triangular (0.54), oval (0.63) and quadrangular (0.51). Similarly, no difference (P > 0.05) was found for facial width (139.08, 143.37, 141.65), maxillary width (76.68, 78.99, 76.91) and mandibular width (103.47, 105.50, 103.11). Conclusions: The majority of cases showed that horizontal and vertical measurements of the face cannot be used as a reference for determining the morphology of the maxillary central incisor crown. It is relevant to analyze and compare other morphological structures to improve the oral health-related quality of life for the conventional denture wearer.

DOI:10.4103/0970-9290.135928  PMID:24992855
Peripheral ossifying fibroma (POF) is a solitary over growth of the gingiva known to arise from the cells of the periodontal ligament. The lesions usually start as a painless overgrowth of the interdental papilla unless associated with trauma and gradually involve the other counter parts of the gingiva. The lesion is more considered to be an inflammatory or reactive process rather than to be neoplastic. Here, the authors present a unique case of multiple POF in a young male adult aged 24 years where surgical excision was carried out quadrant wise. The biopsy specimen from multiple sites revealed similar histopathologic features consistent with POF, but also with the multicentric presentation of POF, which is a unique phenomenon. Multicentric variant of POF is indeed a rare case being only the second case so far which has been documented. Management of such case needs a multidisciplinary approach to prevent the recurrence along with regular long time follow-up.

March-April 2014, 25(2):143-146
DOI:10.4103/0970-9290.135902  PMID:24992840
Aim: To evaluate the histological changes following electrothermal debonding (ETD) of ceramic brackets. Materials and Methods: A total of 50 first premolar teeth from 14 patients were divided into two groups: Group I consisted of 20 teeth which served as control, and the brackets were debonded using conventional pliers. (7 teeth were extracted 24 hours after conventional debonding, 7 teeth were extracted 28 to 32 days after conventional debonding and 6 teeth were extracted 56-60 days after conventional debonding). Group II consisted of 30 teeth and the brackets were debonded using the ETD unit. (10 teeth were extracted 24 hours after ETD, 10 teeth were extracted 28 to 32 days after ETD and 10 teeth were extracted 56-60 days after ETD. Immediately after extraction, the teeth were sectioned and prepared for histological examination. Results: The pulp was normal in most samples of the control group. In group II, mild inflammation was observed in the 24 hour sample while the 28 to 32 day sample showed signs of healing. The 56-60 day sample showed that the pulp was similar to the control group in 6 out of the 10 samples. Conclusion: The ETD of ceramic brackets did not affect the pulp and the changes which were observed, were reversible in nature.

Palathottungal Joseph Antony, Joby Paulose
March-April 2014, 25(2):208-213
DOI:10.4103/0970-9290.135924  PMID:24992853
Aim: The purpose of the study was to compare the force delivery and force decay property of pigmented and non-pigmented elastomeric chains, widely used in orthodontic practice. Materials and Methods: Force delivered by the samples consisting of pigmented and non-pigmented elastomeric chains obtained from 3 manufacturers were tested at 3 time intervals (as received, after 24 hours and 21 days of stretching) to measure the force delivered by the test samples, as well as the force decay over time. Results: The force delivered by the non-pigmented samples was significantly greater than the pigmented ones at all 3 time intervals irrespective of the brand. Force decay was more significant in case of pigmented samples. Force decay was greater noticed in first 24 hours of testing and a gradual decrease in force was observed from 24 hours to 21 days in all test samples irrespective of the brand or color. Conclusion: Non-pigmented elastomeric chains exhibited better force delivery and less force decay percentage when compared to pigmented chains. Though colored elastomeric chains are widely used in present day orthodontic practice to satisfy the younger age group patients, the study ascertains the prudential use of pigmented and non-pigmented chains for efficient and faster orthodontic treatment.

Patrícia Leite-Ribeiro, Thais Feitosa Leitão de Oliveira, Paula Mathias, Elisângela de Jesus Campo, Viviane Almeida Sarmento
March-April 2014, 25(2):214-219
DOI:10.4103/0970-9290.135926  PMID:24992854
Objective: This study aimed to compare digital techniques for evaluating dental enamel de-/remineralization. Materials and Methods: Sixty extracted molars were subjected to a process of de- and remineralization. Radiographs were taken before and after each stage. These radiographs were evaluated by the conventional method and were then scanned and analyzed either with or without the use of image enhancement. Moreover, the gray levels (GLs) of the affected areas were measured. Results: All methods exhibited low sensitivity and identical levels of specificity (99.4%). Analysis of the grayscale levels found statistically significant differences between the initial radiographs (P < 0.05). The mean GL of the carious group was significantly lower than that of the remineralized group. The GL did not differ significantly between the initial and final radiographs of the remineralized group, although the mean of the first group was lower than that of the second, which demonstrated that the remineralization process restored the normal density of the dental enamel. Conclusion: Measurement of the mean GL was sufficiently sensitive to detect small alterations in the surface of the enamel.

P Naina, Dipti Masih, Suma Susan Mathews
March-April 2014, 25(2):263-265
DOI:10.4103/0970-9290.135940  PMID:24992865
Introduction: Schwannoma of the infraorbital nerve is a rare entity, with lesser than a dozen cases reported in literature and only one from India. Report: This article reports a 23-year-old male presenting with a painless swelling in the cheek, which was eventually diagnosed as infraorbital nerve schwannoma. He underwent a complete excision of the tumor via a Caldwell Luc approach and continues to be disease free on 3 year follow-up. Conclusion: Despite its rarity, infraorbital nerve schwannomas should be considered in the differential diagnosis, of upper jaw swelling. We recommend the Caldwell Luc approach as safe, effective and cosmetically acceptable, for anteriorly based infraorbital schwannomas, and review literature on this unusual entity

Implant dentistry is the latest developing field in terms of clinical techniques, research, material science and oral rehabilitation. Extensive work is being done to improve the designing of implants in order to achieve better esthetics and function. The main drawback with respect to implant restoration is achieving good osseointegration along with satisfactory stress distribution, which in turn will improve the prognosis of implant prosthesis by reducing the crestal bone loss. Many concepts have been developed with reference to surface coating of implants, surgical techniques for implant placement, immediate and delayed loading, platform switching concept, etc. This article has made an attempt to review the concept of platform switching was in fact revealed accidentally due to the nonavailability of the abutment appropriate to the size of the implant placed. A few aspect of platform switching, an upcoming idea to reduce crestal bone loss have been covered. The various methods used for locating and preparing the data were done through textbooks, Google search and related articles.

Reorientation simplified: A device for recording and reproducing the path of insertion for removable partial dentures
Vaibhav D Kamble, Rambhau D Parkhedkar
March-April 2014, 25(2):260-262
DOI:10.4103/0970-9290.135939  PMID:24992864
Aim: The record of path of insertion on the dental cast is part of the dentist's work authorization to the dental laboratory technician. The path of insertion record enables the dental technician to replace the cast on a surveyor in the same position that the dentist selected. Analysis of factors that influence the path of insertion should determine a path of insertion that will reduce the potential for dislodgement and promote stability of removable partial denture (RPD). Materials and Methods: The recording of the relation of a cast to a dental surveyor and the transfer of this relationship to the dental laboratory may be done by tripodization, by scoring the base of the cast, or by cementing a reference pin on the cast. Conclusion: Recording the established path of insertion can be difficult when the procedure uses a cemented pin and the casts are mounted in an articulator. This article describes a procedure for innovative dowel pin and sleeve device to record the path of insertion of RPDs, which serves the same purpose as the cemented pin but can be easily removed and replaced.

Inverted papilloma of the hard palate masquerading as a carcinoma
AA Kallianpur, S Goyal, R Yadav, DK Muduly
March-April 2014, 25(2):240-242
DOI:10.4103/0970-9290.135933  PMID:24992860
Inverted papilloma (IP) is a rare, benign tumor of the nose and paranasal sinus. However, it is locally aggressive, the recurrence rate is high and malignant transformation is possible. Until now, IP of the hard palate has rarely been reported in the literature. Here, we reported a case with IP of the hard palate, which clinically presented as a carcinomatous growth. The management of IP is complete surgical excision with a close follow-up to detect early recurrence and/or malignant transformation.

March-April 2014, 25(2):147-149
DOI:10.4103/0970-9290.135904  PMID:24992841
Aim: To evaluate the role of sediment cytology of biopsy specimen fixatives in early diagnosis of oral neoplasms. Materials and Methods: Cytological smears were prepared by centrifuging the fixatives in which the biopsy specimens were received. The smears were analyzed and the cytological results were compared with histological diagnosis. Results: Of 20 lesions studied by sediment cytology, 8 were labeled as benign, 9 as malignant and 3 cases as inconclusive. Final histopathological diagnosis labeled 12 lesions as malignant and 8 lesions as benign. Comparing the cytological diagnosis with histological sections, 17 out of 20 cases were concordant. The overall diagnostic accuracy of 85% was achieved. Conclusion: Biopsy sediment cytology is a good complimentary method to histopathology in the study of oral biopsy material.

Sandeep Kumar, Deepti Yadav, Reena Yadav, Aman Arora
March-April 2014, 25(2):184-187
DOI:10.4103/0970-9290.135916  PMID:24992848
Purpose: This study was aimed to determine the effect of various tray spacer thickness and subsequent repeated pours on the accuracy and dimensional stability of the impression made from monophasic polyvinyl siloxane material. Materials and Methods: Custom trays with different spacer thickness (2, 4 and 6 mm) were used for making an impression of a master model simulating 3 unit fixed partial denture with monophasic polyvinyl siloxane material. These impressions were poured with die stone and repoured. Distance between the reference points were measured and subjected to statistical analysis. Result: Casts obtained from 1 st , 2 nd and 3 rd pour of the impression in 2, 4 and 6 mm spacer thickness tray have similar dimensional accuracy amongst each other and with the master model except in molar diameter and inter-abutment distances of cast obtained from 6 mm spacer thickness tray. Conclusion: The vertical distance of stone dies were decreased, whereas horizontal distance increased as the thickness of impression material is increased. There were statistically non-significant changes occurring among the repeated pours in 2, 4 and 6 mm spacer thickness. Clinical Implication: 2 and 4 mm spacer thickness are acceptable for making an impression for three unit fixed partial denture with monophasic polyvinyl siloxane material and it was not affected by two subsequent (1 st and 2 nd ) repeated pours.

DOI:10.4103/0970-9290.135943  PMID:24992868
Talon's cusp is an anomalous structure that projects palatally from the cingulum areas of maxillary or mandibular anterior teeth. This dental anomaly may pose several pathological, functional and esthetic problems. Talon cusps usually affect a single tooth, but may rarely affect an entire sextant. Such multiple talon cusps may not always occur in association with a syndrome. Furthermore, they may exhibit a genetic pattern of inheritance. This article emphasizes rare occurrence of such nonsyndromic multiple talon cusps in two siblings.
