A case of chronic myeloid leukemia presenting as oral ulcers.

The oral signs and symptoms may reflect undetected serious systemic diseases. Depending on the oral manifestation, the dentists and physicians make attention and focusing on specific diagnoses. Here, we represent one such case which was diagnosed after oral signs and symptoms followed by peripheral smear report as chronic myeloid leukemia. Leukemia is among the most prevalent neoplasia, which represents between 30% and 51% of that total. Leukemia is characterized by uncontrolled production of immature white blood cells, causing a series of clinical and oral manifestations, which are important in disease diagnosis. Due to their clinical importance, all such lesions deserve the full attention of dental doctors. Early detection of leukemia is very important because it provides a favorable prognosis.

Gender determination using diagonal measurements of maxillary molar and canine teeth in davangere population.

BACKGROUND: Mesiodistal and buccolingual measurements of the teeth have been the traditional means of determining gender which sometimes are difficult to measure. AIMS AND OBJECTIVES: To assess the degree of sexual dimorphism in upper permanent canines and first molars using diagonal diameters and to evaluate the applicability of diagonal measurements in sex determination. MATERIALS AND METHODS: Mesiobuccal-distolingual (MBDL) and distobuccal-mesiolingual (DBML) measurements of the crown and cervix of maxillary canine and maxillary molar were taken using digital vernier callipers in 100 upper dental casts obtained from 50 males and 50 females of the age group of 17-25 y. RESULTS: With step wise discriminant function analysis, results were statistically significant with males showing higher diagonal measurement values. The classification accuracy for males was 69% and in females was 73% with overall accuracy of 71%. RESULTS showed that canines exhibited highest accuracy with cervical measurements being more dimorphic. MBDL measurements were found to be more reliable. Most dimorphicmeasurements included right molar cervical MBDL, left molar cervical MBDL followed by right and left molar crown MBDL. CONCLUSION: In cases of tooth rotations, crowding, certain fillings and attritions where traditional mesio-distal and bucco-lingual measurements are not applicable, diagonal measurements could be of help in predicting gender.

Quantitative estimation of sodium, potassium and total protein in saliva of diabetic smokers and nonsmokers: A novel study.

AIMS: The aim of the study was to evaluate the difference in sodium, potassium, total protein in whole saliva in diabetic smokers, diabetic nonsmokers and healthy controls. MATERIALS AND METHODS: Nonstimulated saliva samples were collected from a group of diabetic smokers, diabetic nonsmokers, and controls. Supernatant after centrifugation was used to determine the levels of sodium, potassium, and total protein by using semiautomatic analyzer. RESULTS: There exists a statistical difference in the levels of potassium and total protein between diabetic smokers, nondiabetic smokers, and controls. Difference in the levels of sodium is only significant with nondiabetic smokers and controls. CONCLUSION: Diabetes mellitus is known to alter the composition of saliva. The purpose of this study was to estimate and compare the levels of salivary potassium, sodium, and total protein in smoker diabetic patients and nondiabetic smokers and controls, and to explore potential of salivary electrolytes [Na+, K+] and total proteins as markers. The estimated values of salivary constituents add to the data already recorded in Indian population. However, further studies using large samples are required to evaluate the findings in our study.

Cheiloscopy and its patterns in comparison with ABO blood groups.

OBJECTIVE: The aim of this study is to determine the distribution of different lip print patterns among subjects having different ABO and Rh blood groups and to determine the correlation between their characters and blood groups. MATERIALS AND METHODS: The present study was done on 150 individuals who were randomly selected and blood groups of these subjects were analyzed. RESULTS: The results revealed no association between distribution of lip print (cheiloscopy) pattern and blood groups. CONCLUSION: Lip print pattern does not show any correlation between blood groups.

Determination of sex from tooth pulp tissue.

OBJECTIVE: This study was carried out to determine the reliability of sex determination from teeth pulp tissue. PATIENTS AND METHODS: This study was carried on 60 maxillary and mandibular premolars and permanent molars (30 male teeth and 30 female teeth) which were indicated for extraction. The teeth were categorized into three groups of 20 each (10 from males and 10 from females).Group 1-pulp tissue from teeth examined immediately after extraction. Group 2- and Group 3-pulp tissue examined from teeth one and five month after extraction, respectively. Teeth was sectioned and pulpal cells were stained with quinacrine dihydrochloride. The cells were observed with fluorescent microscope for fluorescent body. Gender was determined by identification of Y chromosome fluorescence in dental pulp. RESULTS: Freshly extracted teeth and for those examined one month later, sensitivity, specificity, positive predictive value, negative predictive value, and efficiency were all 100%. CONCLUSION: The fluorescent Y body test is shown to be a reliable, simple, and cost-effective technique for gender identification in the immediate postmortem period up to one month.
