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
Introduction: Salivary gland tumors account for about 3% of head and neck tumors and the majority are benign in nature. Among these, the most common pathological type is pleomorphic adenoma also called the mixed tumor. It is a kind of tumor containing glandular tissue, myxoid and cartilage-like tissue. As the structure of the tissue is diverse, it is called a “mixed tumor.” Actinomycosis is a chronic suppurative bacterial infection caused by Actinomyces israelii. In this case report, we are presenting a rare co-existence of pleomorphic adenoma and Actinomycosis in the infratemporal fossa. Case description: A 40-year-old female patient complains of pain over the upper left back tooth region for the past 6months. The patient had a past history of a small lesion in 28 region which resulted in constant irritation. The patient had consulted the dentist for the same and underwent extraction of 28 and 38 three years back, which was thought to be the cause of the swell- ing. Conclusion: The case highlights the importance of proper history taking, clinical examination, and histopathological examina- tion in arriving at a precise diagnosis of a lesion irrespective of size and clinical presentation.
ABSTRACT
Verrucous carcinoma (VC) should be considered a distinct clinicopathologic entity different from the more common oral squamous cell carcinoma (OSCC) because of its unique biological behavior. Best way to understand the behavior of these carcinomas is to study them by means of molecular methods, especially in tumor progression tests and Bcl-X is an important antiapoptotic member of the Bcl-2 family and is one of the newest and most useful markers to determine the aggressiveness of many carcinomas. The relationship between this Bcl-X protein and carcinomatous behavior toward it is not studied extensively, which we attempted to evaluate using immunohistochemical analysis in selected carcinomas of the head and neck region. Method: We studied Bcl-X protein expression in sections of thirty OSCC and ten VC samples and correlated this with tumor differentiation. Results: There was a significant difference in cytoplasmic staining of Bcl-X expression with statistical analysis (P < 0.005) for VC and OSCC when compared as a group. No significance was seen among the different histological grades of OSCC and when compared with VC individually. Conclusion: The significant result between OSCC and VC suggests that their biologic course is comparable and can be helpful in differentiating them with each other for establishment of a better treatment protocol.
ABSTRACT
Medicinal and aromatic plants are gift of nature and are being used against various infections and diseases in the world since ages. Species of the genus Bridelia stipularis var scandens is reported to be used traditionally for treating various oral diseases. However, the antimicrobial effect of these plant materials against oral pathogens is not proved. Therefore, we have done the present study. Aim is to find out the anticandidal effect of water extract of Bridelia stipularis against four common oral candidal pathogens. The leaves after identification and authentication by a botanist were collected, air dried, pulverized to fine powder using household blender. The water extract was prepared using cold percolation method. The standard Candida species, Candida albicans, Candida parapsilosis, Candida glabrata and Candida tropicalis obtained from Post Graduate Institute (PGI), Chandigarh was procured. Antifungal activity was determined by Kirby Bauer well diffusion method and Time kill assay. All four species of Candida showed variable results with diameter of zone of inhibition ranging from 12mm to 21mm on Sabouraud’s dextrose agar with both 6 hour and 24 hour peptone water subculture. Time kill assay showed inconsistent results even after 24 hours of exposure with the crude extract of Bridelia stipularis. All four species of Candida causing oral infections are moderately sensitive to crude water extract of dried leaves of Bridelia stipularis.
