Pawankumar Dnyandeo Tekale, Ketan K Vakil, Jeegar K Vakil, Ketan A Gore
April-June 2015, 6(2):226-232
DOI:10.4103/0976-237X.156052  PMID:26097360
This article reports the successful use of mini-screws in the maxilla to treat two patients of age 21-year and 17-year-old girls. Both the patients had a skeletal Class II malocclusion with protrusive maxillary teeth and angels Class II mal-occlusion. Temporary anchorage devices (TADs) in the posterior dental region between maxillary second premolar and maxillary first molar teeth on both sides were used as anchorage for the retraction and intrusion of her maxillary anterior teeth. Those appliances, combined with a compensatory curved maxillary archwire, eliminated spacing, deep bite, forwardly placed and proclined upper front teeth and the protrusive profile, corrected the molar relationship from Class II to Class I. With no extra TADs in the anterior region for intrusion, the treatment was workable and simple. The patient received a satisfactory occlusion and an attractive smile. This technique requires minimal compliance and is particularly useful for correcting Class II patients with protrusive maxillary front teeth and dental deep bite.

DOI:10.4103/0976-237X.156043  PMID:26097353
Statement of Problem: Tetrahydrozoline has been introduced as new gingival retraction agent but its clinical efficacy with widely used conventional retraction agents has not been tested. Purpose: The study was designed to clinically evaluate efficacy of newer retraction agent tetrahydrozoline with two widely used retraction systems i.e., Expasyl retraction system and medicated retraction cords on basis of amount of gingival retraction. Materials and Methods: 30 subjects were selected according to inclusion and exclusion criteria. Maxillary Impressions were made with irreversible hydrocolloid for all subjects. Tray material was used for making the special tray. Latin Block Design was Used in the Study to avoid tissue fatigue. Retraction was done with aluminium chloride; Tetrahydrozoline and Expasyl according to Latin block design. Impressions were poured with die stone. Casts were retrieved and sections were made with die cutter. 3 mm thin slices were obtained. Each slice was used to measure the amount of retraction under stereomicroscope under 20x and images were transferred to image analyser. Results: The amount of gingival retraction obtained by using aluminium chloride as gingival retraction agent was maximum (148238.33 μm 2 ) compared to tetrahydrozoline (140737.87 μm 2 ) and Expasyl (67784.90 μm 2 ).

Santosh Gupta, Ruchi Banthia, Pallavi Singh, Priyank Banthia, Sapna Raje, Neha Aggarwal
April-June 2015, 6(2):153-160
DOI:10.4103/0976-237X.156034  PMID:26097347
Background: The aim of this study was to compare the clinical efficacy of coronally advanced flap (CAF) alone and in combination with autologous platelet rich fibrin membrane (PRF) in Miller's class I and II gingival recessions. Materials and Method: Thirty isolated Miller class I or II sites in 26 subjects were randomly divided into test (15 sites- CAF+PRF) and control (15 sites- CAF alone). Parameters probing pocket depth (PPD), Recession depth (RD), Clinical attachment loss (CAL), Keratinised tissue width (KTW) and Gingival tissue thickness (GTH) were evaluated at baseline, 3 months and 6 months postoperatively. Data was subjected to statistical analysis. P< 0.05 was considered statistically significant. Results: Mean percentage root coverage was 91.00±19.98% and 86.60±23.83% for test and control group respectively. Difference between the groups in all parameters at baseline, 3 months and 6 months was non significant. Complete root coverage was obtained in 12 (80%) and 11 (73.3%) subjects in test and control group respectively. The difference was found to be non-significant. Both groups showed significant differences in all parameters at 3 and 6 months respectively except difference in gingival tissue thickness which was non-significant in control group at 3 months. Conclusion: Combination of PRF to CAF procedure did not provide any added advantage in term of recession coverage in Miller class I and II recessions. Long term trials with more sample size are needed to validate these findings.

April-June 2015, 6(2):215-222
DOI:10.4103/0976-237X.156050  PMID:26097358
Background: There is an increasing amount of stress in undergraduate dental students leading to anxiety, depression, and suicidal attempts/suicide. Aims: This study aims to evaluate anxiety, depression and suicidal intent in undergraduate dental students and to find out the various areas of stress. Materials and Methods: A cross-sectional study was conducted using a semi-structured questionnaire (to assess academic and nonacademic areas of stress) and three scales-Hamilton scale for anxiety (HAM-A); Hamilton depression rating scale (HDRS) and Beck's Suicide Intent Scale (BSI). Descriptive statistics; Pearson's Chi-square test; Multiple ANOVA; Kruskal-Wallis test and Mann-Whitney test were used to analyze the data at the significant level of P ≤ 0.05. Results: In a total of 258 dental undergraduate students, academic areas of stress that were found to be statistically significant were long teaching hours (P = 0.002); high workload (P ≤ 0.001); frequency of tests (P ≤ 0.001) and competition/fear of failure (P = 0.009). Lack of interest in the profession was a statistically significant nonacademic area for stress (P ≤ 0.001). The students of first and final year reported higher anxiety (HAM-A 13.93 ± 6.908 and 16.44 ± 7.637 respectively) and depression (HDRS 14.29 ± 6.302 and 14.22 ± 5.422); whereas suicidal intent was reported almost the same throughout the study sample (BSI 5.65 ± 5.465). Conclusion: An increasing level of anxiety, depression and suicidal intent due to various stressors in undergraduate dental students indicate a need to modify current education system and timely help to have psychological healthy dental professionals in future.

K Vinay Kumar Reddy, Shameena Roohi, Kotya Naik Maloth, K Sunitha, Venkata Satya Ramesh Thummala
April-June 2015, 6(2):266-269
DOI:10.4103/0976-237X.156064  PMID:26097370
Lipomas and hemangiomas are well-known benign lesions of the body. However, their occurrence in the oral cavity is rare. Lipoma accounts for 1-4% of benign neoplasms of mouth affecting predominantly the buccal mucosa, floor of mouth and tongue. Hemangiomas occur mostly on the lips, buccal mucosa, tongue, and palate. Lipomas when superficially placed show yellowish surface discoloration and hemangiomas usually have reddish blue to deep blue color. Here, we report an unusual case of benign tumor occurring in the buccal vestibule.

April-June 2015, 6(2):161-165
DOI:10.4103/0976-237X.156035  PMID:26097348
Purpose: The purpose of this in vitro study was to evaluate and compare the primary marginal accuracy of four commercially available provisional materials (Protemp 4, Luxatemp Star, Visalys Temp and DPI tooth moulding powder and liquid) at 2 time intervals (10 and 30 min). Materials and Methods: A customized stainless steel master model containing two interchangeable dies was used for fabrication of provisional crowns. Forty crowns (n = 10) were fabricated, and each crown was evaluated under a stereomicroscope. Vertical marginal discrepancies were noted and compared at 10 min since the start of mixing and then at 30 min. Observations and Results: Protemp 4 showed the least vertical marginal discrepancy (71.59 μ), followed by Luxatemp Star (91.93 μ) at 10 min. DPI showed a marginal discrepancy of 95.94 μ while Visalys Temp crowns had vertical marginal discrepancy of 106.81 μ. There was a significant difference in the marginal discrepancy values of Protemp 4 and Visalys Temp. At 30 min, there was a significant difference between the marginal discrepancy of Protemp 4 crowns (83.11 μ) and Visalys Temp crowns (128.97 μ) and between Protemp 4 and DPI (118.88 μ). No significant differences were observed between Protemp 4 and Luxatemp Star. Conclusion: The vertical marginal discrepancy of temporary crowns fabricated from the four commercially available provisional materials ranged from 71 to 106 μ immediately after fabrication (at 10 min from the start of mix) to 83-128 μ (30 min from the start of mix). The time elapsed after mixing had a significant influence on the marginal accuracy of the crowns.

Firoz G Kamal, Reginald Ajay Bernard
April-June 2015, 6(2):211-214
DOI:10.4103/0976-237X.156048  PMID:26097357
Background: Oral habits like thumb sucking and nail biting are pernicious habits that act as an adaptive function in obtaining pleasure and subduing anxiety. These habits may also act as carriers of numerous microorganisms into the oral cavity, of which, Enterobacteriaceae members are transient pathogens, which might result in debilitating systemic conditions. Aim: To study the oral carriage of Enterobacteriaceae in children having habit of nail biting and thumb sucking. And to study the association of the organism with the individual's respective plaque indices. Subjects and Methods: Totally, 40 chronic nail biters, 40 chronic thumb suckers, and 20 controls (no habit) (8-15 years old) were enrolled in the study. Appropriate history and their plaque indices recorded. Sterile containers were used to collect the salivary samples and later cultured on Agar plates. Biochemical tests categorized the organisms into subspecies. Statistical Analysis Used: ANNOVA, Student's t-test. Results: Presence of a nail biting habit indicated a higher plaque index, which in turn showed a higher carriage of Enterobacteria spps, predominantly Escherichia coli. Conclusions: Oral surgical intervention in individuals with pernicious oral habits need to be counseled and educated on the possible complications, which might otherwise provide an environment that disseminates these microorganisms resulting in a broad range of local and systemic infections.

S Harveen Kalra, Chandni Monga, K Heena Kalra, S Harshneet Kalra
April-June 2015, 6(2):277-280
DOI:10.4103/0976-237X.156068  PMID:26097373
Background: Nowadays, techniques are being developed to guide and instruct the specialized cellular components of the periodontium to participate in the regenerative process. This approach of reconstruction makes use of understanding of the development of the periodontium and the cellular processes that are involved. Hyaluronic acid is a naturally occurring non-sulfated high molecular weight glycosaminoglycan that forms a critical component of the extracellular matrix and contributes significantly to tissue hydrodynamics, cell migration, and proliferation. Hence, its administration to periodontal wound sites could achieve comparable beneficial effects in periodontal tissue regeneration. Hence, the purpose of the present case report was to assess roentgenographically, the regenerative capacity of Gengigel® in conjunction with bioactive amnion guided tissue regeneration (GTR) membrane in a patient with Grade II furcation defect. Case Presentation: A patient complained of bleeding gums from the lower back tooth region, reportedly found Grade II furcation in the lower right mandibular first molar. After Phase, I therapy, Gengigel® along with bioactive amnion membrane was placed in the furcation area during the surgical phase. Roentgenographic assessment was done at 4 months and 6 months postoperatively. It resulted in complete defect-fill and loss of radiolucency at 6 months. Conclusion: Surgical placement of Gengigel® along with amnion membrane in the furcation defect can significantly improve the periodontal defect morphology.

April-June 2015, 6(2):148-152
DOI:10.4103/0976-237X.156033  PMID:26097346
Objectives: Oral cancer ranks third among all cancers in the Indian population. Human papilloma virus (HPV) plays a significant role in oral carcinogenesis. Population-based subtype variations are present in the HPV prevalence. This study gives an emphasis on the parameters to be considered in formalin fixed paraffin embedded tissues for polymerase chain reaction (PCR)-based research work. Materials and Methods: Cross-sectional study on archival paraffin-embedded tissue samples of oral squamous cell carcinoma (OSCC), epithelial dysplasia, and normal oral mucosa surrounding impacted tooth was amplified by PCR for the E6 gene of HPV type 16 and E1 gene of HPV type 18. Results: HPV 18 was positive in three OSCC cases. There was no statistically significant association of the positivity of HPV with the age, gender or habit. The HPV positive patients had a tobacco habit and were of a younger age group. Conclusion: The presence of HPV in carcinomatous tissue highlights the possible role of HPV in carcinogenesis and archival paraffin embedded tissue specimen can be used for this analysis. Recent studies on genomic analyses have highlighted that the HPV positive tumors are a separate subgroup based on genomic sequencing. The results of a larger retrospective study will help further in our understanding of the role of HPV in carcinogenesis, this study could form the baseline for such follow-up studies.

DOI:10.4103/0976-237X.156042  PMID:26097352
Objective: The aim was to obtain normative data for cephalometric measurements of the upper airway in the North Indian population. Design: Observational study. Setting: University department and teaching hospital out-patient clinic. Subjects and Methods: A total of 180 healthy patients were included out of which 90 were males (age range, 8-16 years), and 90 were females (age range, 8-16 years), with normal skeletal facial profile, no history of snoring, sleep apnea, upper airway disease, tonsillectomy or adenoidectomy, obesity, or pathology in the pharynx. Twenty cephalometric airway measurements, including size of the tongue, soft palate, nasopharynx, oropharynx, hypopharynx, and relative position of the hyoid bone and valleculae were obtained. Landmarks on cephalometric radiographs were digitized and measurements were made using a specially designed computer program. Error analysis of measurements was performed and comparison of measurements according to sex was made. Results: Significant sex dimorphism was seen for the majority of measurements, with the exception of minimal depth of the airway, oropharyngeal depth of the airway, and the soft palate angle with the hard palate. Conclusion: A minimum sagittal dimension of the upper airway was evident despite differences in measurements between sexes. Findings from this study should be a useful reference for the assessment of sleep apnea in the North Indian population.

DOI:10.4103/0976-237X.156065  PMID:26097371
Correction of Class II relationship, deep bite and ectopically erupting canines is an orthodontic challenge for the clinician. A 13-year-old male patient presented with Class II malocclusion, ectopically erupting canines, and cross bite with maxillary left lateral incisor. He was treated with a combination of Headgear, Forsus TM fatigue resistant device [FFRD] with fixed mechanotherapy for the management of space deficiency and correction of Class II malocclusions. Headgear was used to distalize upper first molars and also to prevent further downward and forward growth of the maxilla. Then Forsus TM FFRD was used for the advancement of the mandible. The molar and canine relationship were corrected from a Class II to a Class I. The objectives were to establish good occlusion and enable eruption of unerupted canines. All these objectives were achieved and remained stable.

Núbia I. P. Pini, Rafaela Costa, Carlos E. S. Bertoldo, Flavio H. B. Aguiar, José R Lovadino, Débora Alves Nunes Leite Lima
April-June 2015, 6(2):170-175
DOI:10.4103/0976-237X.156038  PMID:26097350
Background: Enamel microabrasion is an esthetic treatment for removing superficial stains or defects of enamel. Aim: This study evaluated the roughness after enamel microabrasion using experimental microabrasive systems. Materials and Methods: One hundred and ten samples (5 × 5 mm) were obtained from bovine incisors and divided into 11 groups (n = 10) in accordance with the treatment: Microabrasion using 6.6% hydrochloric acid (HCl) or 35% phosphoric acid (H 3 PO 4 ) associated with aluminum oxide (AlO 3 ) or pumice (Pum) with active application (using rubber cup coupled with a micro-motor of low rotation) or passive application (just placing the mixture on the enamel surface); just the use of acids in a passive application (negative control), and a group without treatment (positive control). Roughness analysis was performed before and after treatments. The statistical analysis used analysis of variance (PROC MIXED), Tukey-Kramer and Dunnet tests (P < 0.05). Representative specimens were evaluated using scanning electron microscopy (SEM). Results: There was no significant difference between the acids used (P = 0.0510) and the applications (P = 0.8989). All of the treated groups were statistically different from the positive control. When using passive application, the use of HCl + AlO 3 resulted in higher roughness when compared with HCl + Pum. Additionally, this treatment was statistically different from the passive application of H 3 PO 4 (negative control) (P < 0.05). However, SEM analysis showed that the treatment with AlO 3 resulted in an enamel surface with a more polished aspect when compared with Pum. Conclusion: AlO 3 may be a suitable particle for use in microabrasive systems.

Arpita Saha, Mounabati Mohapatra, Susama Patra, Kaushik Saha
April-June 2015, 6(2):254-256
DOI:10.4103/0976-237X.156060  PMID:26097367
Arteriovenous malformations (AVMs) are rare vascular lesion in the buccal fat pad (BFP). One of the important complications associated with these lesions is phlebolith formation within it. To the best of authors' knowledge, there is no medical literature on AVM with phlebolith formation in BFP till date. The present case is a 12-year-old boy who presented with a swelling in the right side of the face, clinically diagnosed to be sialocele with sialolith. Excision of the mass was done, and histopathology revealed AVM with the formation of phlebolith. This rare entity needs to be kept in mind while evaluating a case of calcification in BFP. The first case of AVM with phlebolith formation in BFP is reported here along with brief review of literature.

Claudio Poggio, Alberto Dagna, Andrea Vinci, Riccardo Beltrami, Lucia Cucca, Luciano Giardino
April-June 2015, 6(2):201-205
DOI:10.4103/0976-237X.156046  PMID:26097355
Background: Chelating agents are believed to aid root canal irrigation and to be able to remove the inorganic smear layer. Aims: The purpose of the present study was to evaluate and to compare the decalcifying capability of different irrigating solutions (Tubuliclean, Largal Ultra, ethylenediaminetetraacetic acid 17%, Tetraclean, Tetraclean NA). Materials and Methods: Sixty maxillary central incisors were used. Root canals were instrumented and irrigated. From each root, four comparable slices of cervical dentin were obtained. At three successive 5-min interval immersion times, the concentration of calcium extracted from root canal dentin was assessed with an inductively coupled plasma-atomic emission spectrometer. Statistical Analysis Used: Data were analyzed by means of Kruskal Wallis and Mann-Whitney tests. Significance was predetermined at P < 0.05. Results and Conclusions: For all irrigating solutions, the maximum amount of Ca 2+ extracted from root canal dentin samples was reached after 10 min contact time except for citric acid-based agents (Tetraclean and Tetraclean NA) which induced a higher and still increasing calcium release even after 10 min contact time. In order to obtain an efficient decalcifying action on dentin and to facilitate the biomechanical procedures, citric acid-based irrigants can be applied.

Bilateral nephrocalcinosis and amelogenesis imperfecta: A case report
Alok Patel, Chetana Jagtap, Chetan Bhat, Rohan Shah
April-June 2015, 6(2):262-265
DOI:10.4103/0976-237X.156063  PMID:26097369
Amelogenesis imperfecta (AI) is a group of hereditary disorders that affect the quality and/or quantity of dental enamel. This paper describes the clinicopathological features of a patient who was born of nonconsanguineous parents and who presented with oral alterations, including yellow and misshapen teeth, intrapulpal calcifications, delayed tooth eruption, and gum enlargement. Scanning electron microscopy of the teeth revealed hypoplastic enamel, and a renal ultrasound detected bilateral nephrocalcinosis, leading to a diagnosis of AI and nephrocalcinosis syndrome. Since nephrocalcinosis is often asymptomatic and can be associated with impaired renal function, dentists who see children with a generalized and thin hypoplastic AI should consider a renal ultrasound scan and referral to a Nephrologist. Children with nephrocalcinosis should also be considered for a dental check.

AM Savita, E Sarun, Shivli Arora, Swathi Krishnan
April-June 2015, 6(2):206-210
DOI:10.4103/0976-237X.156047  PMID:26097356
Context: Periodontitis is predominantly due to exaggerated host response to pathogenic microorganisms and their products which causes an imbalance between the reactive oxygen species-antioxidant in gingival crevicular fluid (GCF). Glutathione is an important redox regulator in GCF and maintenance of stable reduced glutathione (GSH):oxidized glutathione (GSSG) ratio is essential for periodontal health. Aims: The present study was undertaken to evaluate and compare the level of glutathione and redox balance (GSH: GSSG ratio) in GCF of chronic periodontitis patients, periodontally healthy controls and also to evaluate the effect of nonsurgical periodontal therapy on the level of glutathione and redox balance during 3 months postoperative visit. Study Design: Baseline GCF samples were collected from 20 chronic periodontitis patients and 20 periodontally healthy subjects for GSH and GSSG levels estimation. Periodontitis patients were recalled 3 months postnonsurgical periodontal therapy to re-sample GCF. Materials and Methods: GSH and GSSG levels were measured by high-performance liquid chromatography. The values were statistically analyzed by Paired t-test. Results: The mean GSH and GSSG values in GCF were found to be significantly lower in periodontitis patients pre- and 3 months post-nonsurgical periodontal therapy, compared with those in the control group subjects. In addition, the successful nonsurgical therapy even though leading to a significant improvement in the GSH and GSSG levels, does not restore glutathione concentration to the levels seen in healthy subjects. Conclusion: Successful nonsurgical periodontal therapy leads to significant improvement in the redox balance (GSH: GSSG ratio) in chronic periodontitis patients.

The pneumatization of the maxillary sinus often results in a lack of sufficient alveolar bone for implant placement. In the last decades, maxillary sinus lift has become a very popular procedure with predictable results. Sinus floor augmentation procedures are generally carried out using autologous bone grafts, bone substitutes, or composites of bone and bone substitutes. However, the inherent limitations associated with each of these, have directed the attention of investigators to new technologies like bone tissue engineering. Bone marrow stromal cells have been regarded as multi-potent cells residing in bone marrow. These cells can be harvested from a person, multiplied outside his body using bioengineering principles and technologies and later introduced into a tissue defect. We present a case where tissue-engineered autologous osteoblasts were used along with demineralized freeze-dried bone for sinus floor augmentation.

"Social six" teeth refers to the maxillary incisors and canines that play a vital role in the appearance of an individual and absence of any one of them has a significant psycho-social impact. Hence, early treatment and rehabilitation of the same are extremely important. A multitude of treatment options ranging from orthodontic extrusion, extraction followed by implant placement, fixed partial denture, and auto-transplantation have been advocated. This case report discusses the unique amalgamation of platelet-rich fibrin (PRF), demineralized freeze-dried bone graft with use of PRF membrane during auto-transplantation of an impacted central incisor. The authors have focused on maximum usage of autogenous materials in the most economic and least invasive manner. Furthermore, this amalgamation has been used to provide rehabilitation in the least span of time.

Pyogenic granuloma (PG) is an inflammatory reactive hyperplasia of connective tissue. It usually arises in response to various stimuli such as low-grade local irritation, traumatic injury, hormonal factors or certain kinds of drugs. It predominantly occurs in the second decade of life in young females and rarely may cause significantly alveolar bone loss. It managed by conservative surgical excision and removal of causative irritants. This paper presents the case of a PG in a 55-year-old male with severe alveolar bone loss in the affected site, managed by surgical intervention.

Gingival fibromatosis is a condition characterized by a slow, progressive increase in the gingival tissue that develops as either an isolated disorder or as part of the clinical characteristics of diverse syndrome. The present case report describes a rare case of gingival fibromatosis and its management using scalpel in combination with electrosurgery. A 15-year-old girl patient presented with a chief complaint of gingival overgrowth covering all the surfaces upper and lower teeth. The growth was excised with periodontal knife in combination with electrosurgery under local anesthesia. After 1-year of follow-up, healing was uneventful with no recurrence. Combined technique for the removal of gingival overgrowth represents a unique treatment approach where minimal postoperative bleeding and discomfort were observed.

Background: Periodontitis is an inflammatory disease characterized by the loss of connective tissue and alveolar bone. Different factors are associated with the onset and prognosis of this disease, both environmental and genetic. The latter particularly relate to molecules secreted as a function of the host immune response, such as pro-inflammatory cytokines. Studies indicate that the polymorphism c. 3954C > T in the interleukin-1 β encoding gene (IL1B) can be considered as an aggravating factor in the periodontitis condition. Aims: This study aimed to evaluate whether there is an association between the IL1B c. 3954C > T gene polymorphism and the prevalence of periodontitis in the population from Vitσria da Conquista-Bahia, Brazil. Materials and Methods: A total of 347 subjects (134 cases and 213 controls) who provided epithelial tissue of the oral cavity and saliva samples for DNA extraction and quantification of IL1B, respectively, were selected. Genotyping was performed by polymerase chain reaction-restriction fragment length polymorphism followed by electrophoresis in agarose gel. The evaluation of the cytokine concentration was performed by enzyme-linked immunosorbent assay. Statistical Analysis: Statistical calculations involved in this work include Chi-square test, Fisher Exact test, Mann-Whitney and Kruskal-Wallis tests. Results: Our findings revealed that: (i) No statistically significant relationship between periodontitis and the polymorphism studied was observed; (ii) no significant difference between the concentrations of IL1B in saliva between the case and control subjects and between the genotypes of these individuals and the concentrations of this cytokine. Conclusions: We conclude that, in the sample evaluated, the IL1B c. 3954C > T polymorphism did not present as an etiological factor for periodontitis.
