Background: Several methods have been employed for diagnosing inflammatory conditions including biomarkers, enzymes and various other clinical parameters. Dermatoglyphics is one such field which has gained entry in Forensic Medicine, Forensic Odontology and in General Medicine for diagnosing chronic inflammatory conditions. Periodontitis is a chronic inflammatory condition associated with destruction of periodontal tissues. This study aimed to assess the relationship between the fingerprint patterns and chronic periodontitis Methods: A total of 60 patients, belonging to both healthy and chronic periodontitis subjects were assessed by a commercially available fingerprint scanner. All the fingerprint images were assessed for the fingerprint pattern and the ridge count manually. The results were tabulated as percentage frequency distribution for the type of fingerprint pattern. The ridge count is shown as mean ± SD. Unpaired t test was applied to test for statistical significance. Results: The frequency distribution showed equal percentage of Radial Loop type of fingerprint pattern in subjects of both Health and Chronic Periodontitis. Statistical analysis showed Plain Whorl type of fingerprint pattern more significant in subjects having Chronic Periodontitis Conclusion: It was concluded that there might be a relationship between type of fingerprint pattern to the chances of a person having Chronic Periodontitis.

BACKGROUND: Dermatoglyphic patterns that are often utilized in judicial and legal investigations are valuable in diagnosis of many diseases related to genetic disorders. Caries, being infectious in origin, might be related to genetics as well. Hence, these patterns are of significance in predicting caries development.MATERIALS AND METHODS: DMFT (decayed, missing, filled teeth) score of 300 female subjects within the age group 0f 18-25 years were recorded and accordingly divided into 3 groups of 100 each; group 1 (DMFT score=0), group 2 (DMFT score < 5) and group 3 (DMFT score ≥ 5). Dermatoglyphic patterns were recorded using Cummins and Midlo method. pH meter was used for recording salivary pH accurately. Fingerprint patterns and salivary pH recorded were correlated with DMFT scores of subject and control groups. Statistical analysis was performed using ANOVA and Chi-square tests (P < 0.05).RESULTS: The mean salivary pH was least in group 3. The predominant dermatoglyphic pattern observed in groups 1 and 2 was loop pattern whereas, in group 3, whorl pattern was predominant. The TFRC (total finger ridge count) was higher in group 3 compared to the other two groups.CONCLUSION: Caries-free people showed inflated frequency of loops, whereas subjects with high decay score had additional share of whorls. The TFRC was higher in individuals with high DMFT score, and salivary pH was inversely proportional to the DMFT score.

ABSTRACT The authors report a female patient with XXi constitution for the long arm of the X chromosome associated with thyroid abnormalities, high digital ridge count and chronic suppurative otitis media. This is followed by a discussion of the correlation between genotype and phenotype, comment on the Lyon hypothesis, the relationship of thyroid abnormalities to this condition, autoimmune disease, unbalanced sex chromosomal constitution and the association with a high total digital ridge count. Finally a single hypothesis is proposed for the associated clinical entities that have been found and the suggestion that the classification of this particular type of gonadal dysgenesis be considered as a new syndrome, the »XX-isochromosome syndrome«.

Dermatoglyphics is the scientific study of epidermal ridges and their configurations on the palmar region of hand and fingers and plantar region of foot and toes. Diabetes mellitus is a metabolic disorder characterized by hyperglycemia resulting from defect in insulin secretion, action or both. Dermatoglyphic patterns are genetically determined and can be used as supportive for diagnosis of various hereditary disorders including T2DM. This study was carried out to compare palmar dermatoglyphic pattern in T2DM and control group and compare with previous studies. A hospital based case control study was conducted 100 cases of T2DM are taken from Basaweshwar hospital Gulbarga, and another 100 persons are included as control group. The palms and fingers are smeared with ink to bring out the dermatoglyphiic patterns which were subsequently studied.There was increased number of whorls and decreased number of ulnar loops in both T2DM patients compared with normal individuals. Total finger ridge count and Absolute finger ridge count is increased in both T2DM patients and there is also increased atd angle. The knowledge of dermatoglyphics in patients with T2DM and essential hypertension can be utilized to find out genetic correlation. The existence of such relation might be important for the screening programme for prevention of T2DM.

Abstract Background and aims : Syndactyly is congential fusion between fingers which may vary from simple fusion of skin to fusion betweeo bony componeots of fingers. The aim of this study was to find out the range of dermatoglyphic abnormalities io syndactyly patient because of close association between underlying tissue (derived from mesoderm) and overlying epidermis (derived from ectoderm) duriog embryogenesis of hand. Materials and methods : Present study was carried out io 20 patients with congenital syndactyly of fingers. The authors evaluated fingertip patterns, axial triradius, palmar pattern, flexion creases, a-b ridge count, digital triradii and pattern intensity. Results : Remarkable dermatoglyphic variations were observed io syndactylous hands, which were rare io normal hands. Conclusion : There are certain specific associations between anomalous hands and dermatoglyphic patterns indicating that underlying mesenchyme influences the development of epidermis derived from ectoderm and so the ridge pattern.
