ABSTRACT
Background: Stature plays a major role in forensic identification. It is also considered to be one of the fundamental compo- nents of physical anthropology. When a full skeleton is not available, stature can be estimated from incomplete human remains. Teeth form an excellent material for anthropological, genetic, odontologic and forensic investigations. Various studies have ventured to ascertain the usefulness of tooth crown measurements in stature prediction. Methodology: Tooth lengths of all 28 teeth except 3rd molars were measured on digital OPG using inbuilt software IMPAXH (Agfa, Belgium). Stature was measured from the vertical distance from the vertex of head to the floor. Correlation between the tooth length and height of an individual was done by Pearson correlation test and linear regression analysis for prediction of stature from tooth length. Result & conclusion: Overall the results revealed that individual tooth variables have a good correlation with stature with r value ranging from 0.12-0.57 and p value less than 0.05. Among the tooth lengths, the length of the maxillary right molars showed the highest correlation with stature followed by maxillary right premolars and maxillary right canine than the other teeth. Regression equation was generated from tooth length, to predict height.
ABSTRACT
Novel coronavirus has recently gained attention of the global community after it was first reported from Wuhan, China. It has been declared as global health emergency with implications to all people. Droplets of bodily fluids, such as saliva or mucus, from an infected person are dispersed in the air or on surfaces by coughing or sneezing and could be the main source for the further spread of infection. All healthcare professionals including Dental Surgeons should help to prevent transmission of this deadly virus. It’s a virus affecting both human and animals and spreads from animals and person to person in close proximity, similar to other respiratory illnesses, such as the flu. This review article mainly highlights the types, epidemiology, transmission and addresses the implications of 2019 n-CoV from the health professionals perspective and discusses the necessary preventive precautions that should be strictly followed in a dental setup so as to prevent further spread of infection.
ABSTRACT
Background and Objectives: Quid-chewing habit is a common and old tradition in India. It causes various potentially malignant disorders. Therefore, a study was undertaken to analyze the association of various quid-chewing habit patterns and different oromucosal lesions. Materials and Methods: A cross-sectional study was conducted on 150 cases, where all the individuals selected were having quid-chewing habit and oromucosal lesions. Detailed habit history was taken through preformed questionnaire, clinical examination was done, and the lesion was subjected to incisional biopsy and confirmed histopathologically. Results: The male to female ratio of various quid-chewing habit and oromucosal lesions was 9:1. The middle aged were more commonly involved. Of the various types of quids chewed, a combination of processed betel and processed tobacco which is commercially available was used by majority of the individuals. Oral submucous fibrosis (OSMF) was seen in majority of the cases. Interpretation and Conclusion: The present study confirms the association between betel, tobacco, and various lesions such as OSMF, leukoplakia, chewer's mucosa, lichenoid reaction, and chemical burn. It also confirms the strong association of betel to OSMF and tobacco to leukoplakia
ABSTRACT
Aims: The frequency, with which restricted mouth opening is encountered in the clinical practice, makes it essential to establish what constitutes the normal range. This study was undertaken to evaluate the normal range of mouth opening in adult population in south India. Settings and Design: randomized clinical study conducted on dentate adult patients to evaluate the normal range of mouth opening. Materials and Methods: 500 healthy patients aged between 18-59 were randomly selected and divided into four groups according to their age ranges. The maximum inter-incisal distance and width of right and left three fingers at the first distal inter-phalanges were measured using vernier calipers. Statistical analysis used: ANOVA test, student t test and pearsons correlation test. Results: The mean value and range of maximum mouth opening of 50.3mm±6.26mm for males and 49.9mm±6.74mm for females was recorded. These values were significant and correlated with the width of three fingers. It was found that the greatest mean maximum mouth opening was recorded in youngest age group and lowest was recorded in older age group in both genders. Conclusions: The mean mouth opening value decreases with age and is lesser in females as compared to males of same age. This study demonstrated that individuals in all the four groups were able to vertically align their right and left three fingers between the upper and lower central incisors upto the first distal interphalangeal folds thus suggesting that, width of three fingers can be used as 'tool' to distinguish 'normal' from 'restricted' mouth opening.
ABSTRACT
Background and Objectives: Oral submucous fibrosis (OSF) is a chronic condition of the oral cavity which results in permanent disability. A number of studies have proven that the management of premalignant diseases should include antioxidants. Therefore, a study was carried out to evaluate the efficacy of spirulina as an antioxidant adjuvant to corticosteroid injections in the management of 40 oral submucous fibrosis subjects of south Karnataka and north Kerala. Materials and Methods: An intervention study was conducted on 40 oral submucous fibrosis cases, 40 patients were divided into two groups, group A (spirulina group) and group B (placebo group). Group A received spirulina 500 mg twice daily and biweekly intralesional steroid injection of Betamethasone 4 mg/ml for 3 months and group B was given placebo capsules twice daily and biweekly intralesional steroid injection of Betamethasone 4 mg/ml for 3 months. The results were analyzed with the paired " t" test and the unpaired " t" test. Results: Clinical improvements in mouth opening was significant in the posttreatment period in both Spirulina and placebo groups. Both the groups showed statistically significant reduction in burning sensation. However, when both groups were compared, mouth opening and burning sensation was found to be statistically very highly significant in favor of the spirulina group. Conclusion: Spirulina can bring about clinical improvements in OSF patients. The observed effects suggest that spirulina can be used as an adjuvant therapy in the initial management of OSF patients. However, studies involving larger samples and longer period of treatment follow up are suggested in the future.
ABSTRACT
Fusion has been described as a developmental anomaly characterized by the union of two adjacent teeth. Few cases of this rare anomaly in primary dentition have been reported in Indian population. A rare case of bilateral fusion between primary mandibular lateral incisors and canines is presented in this report.
