<![CDATA[Oral squamous cell carcinoma (OSCC) accounts for more than 90% of the reported oral cancer cases inthe world. Even though the habits such as tobacco usage, smoking and old age are the main risk factors fordeveloping oral squamous cell carcinoma some factors like chronic mucosal irritation(CMI) from mechanicaland functional factors also play a significant role in the etiology of oral squamous cell carcinoma. The aimof this study was to analyse the prevalence of oral squamous cell carcinoma with history of chronic mucosalirritation and to evaluate various parameters like gender, age, site of the lesion and etiology of chronictrauma in OSCC cases with chronic mucosal irritation history. This retrospective study included a samplesize of n= 78 ( 73 = OSCC with other etiology, 5= OSCC with etiology of chronic mucosal irritation). Dataregarding the sample cases were selected after the review and analysis of records of about 86000 patientswho visited our institution between june 2019 and march 2020. The retrieved data were tabulated in MSExcel and exported to SPSS for statistical analysis. Prevalence of oral squamous cell carcinoma cases withchronic mucosal irritation history was 6.41% for a duration of 8 months. Etiology associated with chronicmucosal irritation was found to be tooth related factors in all the sample cases. 80% of the oral squamous cellcarcinoma cases associated with chronic mucosal irritation history were males and 20% were females and80% of the OSCC samples with CMI were above 40 years of age. In 60% of OSCC with CMI history werefound to be on buccal mucosa followed by tongue and gingivobuccal sulcus. The present study providesan overview and explains the need of considering chronic mucosal irritation as an etiological factor for thedevelopment of OSCC without the association of tobacco habit.]]>

<![CDATA[Oral squamous cell carcinoma (OSCC) is more common with 90% of malignant neoplasm in oral cavity.Multiple factors leading to OSCC like genetic alterations, ?hr???? exposure, micro environmental carcinogens,premalignant disease like oral epithelial dysplasia, mitochondrial membrane damage and viruses infectionslike HPV (human papillomavirus). RETN gene belongs to the family of mouse resistin-like genes. Humangenetic variations are found to influence inter-individual variation observed in disease susceptibilities, drugresponse, response to an infectious disease. At the molecular level these sequence variations influence geneexpression, protein production, function, disease susceptibility in particular individuals. The present in silicostudy determines the possible association of RETN polymorphism with that of oral squamous cell carcinomain different populations. In this study the RETN gene polymorphism rs321975 was analysed in comparisonto the global frequencies. The present study attempts to identify the possible reason for the selection of “A”allele in the south asian population. Furthermore, genotyping analysis has to be performed in a south Indianpopulation to ascertain the association between RETN polymorphism (rs3219175) and OSCC.]]>

<![CDATA[Posterior crossbite refers to inadequate transversal relationship of maxillary and mandibular teeth. Posteriorcrossbite can be unilateral left, unilateral right or bilateral. The causes of this malocclusion are deleteriousoral habits, early loss of primary teeth, hereditary factors and environmental factors. It is important to knowthe prevalence of posterior crossbite in order to provide proper treatment as early as possible. Posteriorcrossbite when not treated early, can result in skeletal changes. The aim of the study was to assess theprevalence of posterior crossbite in children of chennai. The present study was a retrospective observationalstudy conducted in a university dental hospital located in Chennai. Data of 7415 Pediatrics patients betweenJune 2019-March 2020 were reviewed. Patients from 6 to 13 years who had posterior crossbite were noted.This was followed by Excel tabulation . Data analysis was done in SPSS software using Chi square testfor comparison of groups. About 1.4% children visiting university dental hospitals among 4292 childrenhad posterior crossbite. Children of 10 to 13 years had more prevalence of posterior crossbite (P=0.349,statistically not significant) and prevalence of posterior crossbite was more in boys than girls (P= 0.175,statistically not significant)]]>

<![CDATA[Hand sanitizers are helpful to decrease infections in the hand. Alcohol based hand sanitizers are used incommon because alcohol is an antiseptic. Face mask has many layers which removes dust and microorganismwhich is present in the air. The benefit of hand sanitizer and face mask is to control the further spread ofdisease among people. Usage of hand sanitizer is one of the hygienic practices. Face masks protect usfrom disease spread and protect us from pollution Hand sanitizer has 60% of alcohol content which killsmicroorganisms. The aim of the study is to assess the awareness about hand sanitizers and face masks in thisdisease spread among college students. In previous studies usage of face mask and hand hygiene are highamong adults. Hand sanitizers cannot be used by people having allergies because in some sanitizers theyhave 90% of alcohol content which causes allergies. Alcohol based sanitizers are accepted being used byabout 95% of people. This study consists of 15 self structured questionnaires. The study was approved by theInstitutional Review Board. The data was collected and evaluated in the SPSS and the statistical significancewas analysed in chi-square. We conclude that many are aware about the usage of hand sanitizer and facemask controlling the disease spread.]]>

<![CDATA[Restoration of decayed primary teeth is important and significant for proper maintenance of child healthand also for the development of their teeth. The materials preferred for restoration are composite, glassionomer, compomer, resin modified glass ionomer cement, stainless steel crown. Therefore it is importantto have knowledge about materials and its uses which makes the durability of restoration longer. The aimof the study is to assess the knowledge and awareness of various dental biomaterials used in pediatricpatients among the undergraduate dental students. A questionnaire of 12 questions based on different dentalbiomaterials used in pediatric patients was prepared and it responded by 140 students. Data was collectedand with the help of SPSS software data was analysed. Only 9% of students were aware that pit and fissuresealants are bound to tooth surface by both chemical and mechanical bonding. Only 33% opted correctlythat stainless steel crowns are semi permanent restorations. Amalgam was the most used restorative materialin primary molar by both the male and female students. The material of choice for restoring primary molarswith proximal caries and in multi surface carious lesions is glass ionomer cement. The students consideredease of manipulation and durability of the restorative material while selecting it for use in pediatric cases.Within the limitations of this survey, it can be concluded that the participants have an average level ofknowledge about various dental biomaterials used in pediatric patients.]]>

<![CDATA[Initial arch wires are the firsts arch wires to be inserted into the fixed appliance at the beginning of orthodontictreatment and are used mainly for the alignment of teeth by correcting crowding and rotations. With anumber of different types of orthodontic arch wires available for initial tooth alignment, it is importantto understand which wire is most efficient. The purpose of this study was to evaluate the choice of initialalignment archwires in treating patients with moderate to severe crowding with the MBT and Damonappliances. Sample included 50 patients aged 18 years and above,selected from the pretreatment recordsof the patients reported to the Department of Orthodontics,Saveetha Dental College,Chennai.Results ofthe study was obtained by evaluating the initial archwires used in case of MBT and Damon appliances.This study revealed that 85.7% out of the 35 MBT cases used 0.014 NiTi as the initial archwire and all ofthe Damon cases started with 0.013 CuNiTi.The collected data were entered into an Excel sheet(MicrosoftExcel 2007) and statistical analysis done. The association between gender and initial alignment archwiresin moderate to severe crowding cases was found using Chi-square association test in IBM SPSS software,which showed a statistically not significant difference (p -value >0.05) , hence there is no gender differencein the choice of initial alignment archwires in moderate to severe crowding patients.]]>
