Authors: Vadavadagi Suneel V , Dhananjaya Kiran M , Yadahalli Rashmi P , Lahari M , Shetty Shilpa R , Bhavana BL 
Published: July 2019

ABSTRACT

Introduction
Endodontic restoration becomes a challenging task for the clinician because of severe loss of coronal tooth structure owing to trauma, caries, restorative, and endodontic procedures. The restoration of these teeth requires the use of a post and core as individual units or as abutment supports for fixed or removable restorations in a predictable long-term manner.

Aim
To compare and assess the compressive bond strength of glass, quartz, and carbon fiber posts restored with porcelainfused- to-metal (PFM) crown.

Materials and methods
A total of 45 upper central incisor teeth having straight root canals, similar anatomically root segments, and fully developed apices were selected. Teeth were divided into three groups of 15 teeth after endodontic treatment. Group I: Teeth inserted with the prefabricated glass fiber post. Group II: Teeth inserted with the quartz fiber post. Group III: Teeth inserted with carbon fiber post. The posts were placed and core was fabricated using composite restoration followed by PFM crown cementation using adhesive resin. Compressive load required to fracture the tooth was measured using a universal loading machine. The difference between the variables was assessed by one-way analysis of variance, followed by Tukey's post hoc test.

Results
The compressive strength exhibited by carbon fiber posts was highest with a mean of 668.33 ± 26.397, followed by quartz fiber post (635.80 ± 30.390). Least compressive strength was exhibited by glass fiber post (567.53 ± 26.632). An analysis of variance shows statistically highly significant difference (p < 0.005) among the posts used.

Conclusion
This study concluded that the carbon fiber posts had higher compressive strength than other quartz, glass fiber posts.

Clinical significance
Endodontic treatment results in loss of a significant part of the tooth structure. Posts restore these teeth and provide retention.

ABSTRACT

Introduction
Mishri is one of the form of smokeless tobacco, which is a roasted, powdered preparation made by baking tobacco on a hot metal plate until it is uniformly black, after which it is powdered. It is noted that mishri use is more commonly used by the women of low socioeconomic status, hence the need was felt to conduct this study among women mishri users of slums. Also, the consequences of mishri use are little known, hence an effort is made to find out its ill-effect on oral health.

Objective
To assess knowledge, attitude, and practice (KAP) among women using mishri regarding its effects on their oral and general health.

Materials and methods
A 6-month KAP study was conducted among 100 women who were using mishri. Snowball sampling was used. Oral examination of the participants was also done for oral potentially malignant disorders, such as leukoplakia, erythroplakia, oral submucous fibrosis, and hyperkeratinized pouch.

Results
About 61% of the population used mishri for cleaning the teeth and others used it as quid; 0.85% of the total participants knew that the use of mishri may lead to precancerous lesions/conditions. Only 17% knew that mishri use can cause gum disease; 84% of the population was willing to quit the habit of using mishri.

Conclusion
It is concluded that all the participants had poor knowledge. Attitude toward quitting mishri use was found to be good. About 4% of the participants reported about quitting the habit.

Clinical significance
There is need to create awareness regarding harmful effects of mishri usage in this particular area to improve oral health status.

Treatment of Extrusive Luxation in Permanent Teeth: Literature Review with Systematic Criteria
Authors: Okamoto Roberta , de Faria Lorraine P , Amaral Marina F , de Almeida Melyna M , Brandini Daniela A , Poi Wilson R 
Published: July 2019

ABSTRACTIntroductionExtrusive luxation is a traumatic dental injury caused by the action of oblique forces, characterized by partial displacement of the tooth out of its socket. The ideal treatment for this type of trauma involves repositioning the tooth in its socket. However, in cases where the tooth cannot be repositioned, different options may be considered, such as intentional reattachment and orthodontic intrusion. The aim is to review the literature on the extrusive luxation of permanent teeth while assessing the risks of complications for two methods of delayed treatment for extrusive luxation.Materials and methodsAn electronic search from August 2005 to August 2014 was performed by two reviewers independently, and conflicts were resolved by a third reviewer. The databases used were PubMed and Scopus; the reviewers performed a manual search of the following journals: Dental Traumatology, American Journal of Orthodontics, and Clinical Oral Investigation.ResultsAfter removing the duplicate studies, 328 articles were found. Out of these, 321 were rejected as not addressing the proposed research topic. In addition, five articles were excluded because apical repositioning was used for treatment. Therefore, four articles formed the basis of the study.ConclusionFactors, such as root formation, the degree of tooth mobility, and the presence of tooth vitality were decisive for the choice of treatment. However, both treatments were effective and showed favorable results, i.e., without periodontal and root damage.Clinical SignificanceKnowledge of the risks of complications among two methods of delayed treatment for extrusive luxation, as well as other important factors to take into consideration when choosing a treatment assists dentists in improving the prognostic.How to cite this articleAmaral MF, de Almeida MM, de Faria LP, Brandini DA, Poi WR, Okamoto R.

ABSTRACT

Purpose
To report a case of post-LASIK unilateral corneal ectasia.

Setting
Department of anterior segment and Refractive surgery, Rothschild Foundation, Paris.

Case report
A 33-year-old woman was referred with a history of unilateral post-LASIK ectasia in her left eye, 18 months post operatively. Her best-corrected visual acuity was 20/20 with a manifest refraction of +1.75 (–4.75 × 90). Orbscan ii® revealed an inferior steepening associated with irregular astigmatism. The preoperative Placido topographies revealed a slight skewed radial axis in the right eye associated with an inferior-superior keratometry difference of 1.6 Diopters at 3 mm. in the left eye that developed ectasia, regular symmetric astigmatism was present. Uncorrected visual acuity improved to 20/25 2 weeks after keraRing® segment insertion.

ABSTRACT
To describe a case of very asymmetric ectasia successfully treated by femtosecond laser-assisted intracorneal ring segment implantation, in which the diagnosis of unilateral ectasia in the right eye was based on the clinical findings including history, follow-up, and advanced diagnostic data. The patient's history was positive for ocular allergy with moderate- to-intense eye rubbing only in the right eye. The uncorrected distance visual acuity was 20/63 in the right eye and 20/32 in the left eye. The corrected distance visual acuity (CDVA) was 20/40 in the right eye (-1.75-4.00 × 35°) and 20/16 in the left eye (-0.50-0.25 × 115°). After femtosecond laser-assisted intracorneal ring segment implantation, the right eye improved CDVA to 20/20-1. Concerning ectasia/keratoconus diagnosis, the left eye remained stable over 1 year of follow-up with unremarkable topometric, tomographic, and biomechanical findings. Epithelial thickness mapping by spectral domain optical coherence tomography and very-high-frequency digital ultrasound demonstrated epithelial thickness within normal limits in the left eye. Advanced diagnostic methods along with clinical data enable the distinction from unilateral ectasia cases and subclinical (fruste) keratoconus. Literature review is also performed along with case presentation and discussion.

Serum Vitamin B12 and Folate Levels in Mothers and their Newborns: An Observational Study
Authors: Krishnaswamy Priyanka H , Prabhu Sujatha , Pandith N Ashwini , Shetty Achal 
Published: July 2019

ABSTRACT

Aim
To estimate the average serum values of vitamin B12 and folate in women with a term pregnancy and the cord blood of their newborns. To find if any correlation exists between the levels of serum B12 and folate in the mother and that of the neonate.

Materials and methods
A prospective observational study of serum B12 and folate levels and the respective cord blood concentrations of 51 term, nonanemic, pregnant women and in the cord blood of their newborns at delivery.

Results
Fifteen women were B12 deficient (29.4%) with the mean being 189.25 ± 94.2 ng/mL and 14 neonates were B12 deficient (27.45%) with their mean being 321.86 ± 143.68 ng/mL. One woman was folate deficient (1.96%) with the mean being 13.13 ± 5.15 ng/mL and one neonate was folate deficient (1.96%) with the mean being 15.68 ± 4.61 ng/mL. There was a significant correlation between maternal and neonatal B12 levels with a Pearson's coefficient of 0.74 (p-value of < 0.01) and a significant correlation between maternal and neonatal folate levels with a Pearson's coefficient of 0.44 (p-value of < 0.01).

Conclusion
There is a high incidence of maternal B12 deficiency in the Indian community, which has a positive correlation with neonatal levels. Treatment of B12 and folate deficiency should be a part of routine antenatal treatment, and neonates should be followed up and treated if found to be B12 or folate deficient.

Clinical significance
In India, where large numbers of women are anemic, deficiency of vitamin B12 and folate is overlooked when treatment of anemia is undertaken in most hospitals. In addition, women with undetected and subclinical deficiency may transmit it to their newborns with a cycle that is self-perpetuating unless broken with adequate intake or supplementation.

Published: July 2019

ABSTRACTIntroductionIncrease in life expectancy implies the need for more attention to the health of the elderly population, and oral health is not an exception. This study determined the frequency of major oral and dental health problems among institutionalized elderly adults in Qazvin, Iran.Materials and MethodsIn this cross-sectional study, 112 residents of geriatric nursing homes participated. History of systemic diseases and oral symptoms was asked and recorded; then, participants undertook a clinical intra- and extraoral examination. Examination consisted of oral mucosa, periodontal and dental assessment, and temporomandibular joint (TMJ) assessment.ResultsIn total, 93 women and 19 men with an average age of 74.9 (±14.7) and 71.6 (±11.3) years respectively, were examined. A total of 73 patients were completely edentulous. Examination of the oral mucosa showed that 48 patients (42%) had changes in their oral mucosa. Pale mucosa and fissure tongue had the most frequency. However, denture stomatitis was the most prevalent disorder related to the denture. Xerostomia was the most frequent complaining symptom (67.8%) followed by dysphagia (53.7%) and dysgeusia (25.8%). A total of 26 patients (23.2%) had abnormal “clicking” sounds during TMJ assessment.Decayed, missing, and filling teeth (DMF) index in 39 dentate patients revealed 89.7% had decayed teeth, 100% had missing, and 2.6% had filling teeth. Community Periodontal Index of Treatment Needs (CPITN) revealed more than half of the participants had deep or shallow pockets.ConclusionOral and dental health of elderly people in this study was not acceptable. They should be persuaded that there are continual needs for oral health care. Oral examination should be performed as part of development programs for older adults.How to cite this articleMojabi KB, Azimi S, Khansari M.

Glandular Odontogenic Cyst Mimicker: A Novel Entity
Authors: Azmi Kehkashan E 
Published: July 2019

ABSTRACTGlandular odontogenic cyst (GOC) is an uncommon developmental odontogenic cyst of jaws with a frequency of approximately 0.2%. Because of its aggressive biological behavior including its malignant transformation potential, recently collaborative efforts by few researchers have laid down certain histopathological criteria segregating it from its mimickers which include dentigerous cyst, lateral periodontal cyst (LPC), or botryoid cyst, radicular cyst, and central low-grade mucoepidermoid carcinoma. Therefore, cautious histopathological evaluation is necessary of GOC mimickers in order to prevent its overdiagnosis. Here, we present a case of GOC mimicker in a 12-year-old male patient in left maxillary region.How to cite this articleAzmi KE, Patel S, Pathak J, Swain N.

Published: July 2019

ABSTRACTAim of the studyTo determine the solubility of nanohybrid (NH) composite resins when immersed in saliva substitute and distilled water.Materials and methodsA total of 60 disc-shaped samples (n = 30) were prepared in teflon molds of diameter 10 mm × 2 mm thickness from two NH composite resins. They were light-cured following which the samples were removed and weighed three times using a digital balance. Samples were then immersed in test solutions, i.e., 100 mL of distilled water and saliva substitute each stored for 24 hours and 7, 14, 21, and 28 days in an incubator at 37°C at 100% humidity. At the time intervals mentioned, the samples were removed from the incubator, washed with distilled water, blotted dry, and weighed. Samples were again immersed in fresh test solutions. Difference in preweight and postweight of samples was calculated and data were analyzed using appropriate test by testing normality. A p-value < 0.05 was considered to be significant.ResultsThe results were analyzed using one-way analysis of variance (ANOVA). As observed from the baseline weight to the 28th day weight, there was a loss of weight of the samples in all the groups except NH composite resin (Flash) in distilled water.ConclusionFrom the results of the study, it was observed that there was no statistically significant difference in weight, with respect to the solubility of the two NH composite resins and the two solutions tested. Clinical significance of the study is that the NH composite resin that shows lesser solubility can be the choice for an esthetic restorative material in patients for long-term results.How to cite this articleMahajan RP, Shenoy VU, Sumanthini MV, Walzade PS.

Cysticercosis presenting as Neck Swelling: A Rare Case diagnosed on Ultrasound Report
Authors: Chandak Manoj G , Rawlani Shivlal M , Chandak Rakhi M 
Published: July 2019

ABSTRACTIntroductionCysticercosis is a condition that occurs when humans are infested by the larvae ofTaenia solium, acting as an intermediate host instead of definitive occurrence in neural and extra-neural forms. The latter commonly involves subcutaneous tissue, skeletal muscles, and eyes.Aims and objectivesOral cysticercosis is a rare event, and it represents great difficulty for clinical diagnosis. In present report we report a case of cysticercosis in the right submandibular region where it presented as a large, soft cystic swelling and tried to explain the clinical sign & symptom of oral cysticercosis. We emphasize on the importance of ultrasonographic and routine microscopic examinations for the diagnosis of even apparently innocuous lesions in submandibular regions.ResultsThis is a very rare case of oral cysticercosis showing neck swelling extended from the lower border of the mandible to the thyroid cartilage. The diagnosis was made by sonography and confirmed by gross and microscopic examination of cysticercosis cellulosae. In ultrasonography, there was well-defined cystic lesion with hyperechoic eccentric tiny nodules.How to cite this articleChandak RM, Chandak MG, Rawlani SM.

Authors: Sahni Daisy , Aggarwal Anjali , Gupta Tulika , Kaur Harjeet , Chawla Kunal , Goyal Suresh K 
Published: July 2019

ABSTRACT
The congenital anomalies of kidney are not uncommon. The incidence of renal anomalies varies from 1:400 for horseshoe kidney to 1:10,000 for bilateral renal agenesis. The most of this available data is from western populations. Little or no data is available on incidence of renal anomalies in Indian population. Our objective was to determine the incidence of congenital renal anomalies in Indian population. A retrospective analysis of observations made from 1,900 consecutive autopsies for presence of congenital renal anomalies was done. In 1,900 autopsies, there were nine cases of congenitally anomalous kidneys (42%). These anomalies included three cases of horseshoe kidney (16%), two cases of extrarenal calyces (12%), and one each of renal ectopia with fusion, trilobar kidney, polycystic kidney and unilateral renal agenesis. The incidence of renal anomalies in Indian population is relatively less as compared to their western counterparts.
