No full textHeritability of Lip Print and Finger Print Pattern among South Indian Population
No full textBACKGROUND:
Establishing human identity using skeletal and dental trait provides comprehensive data for routine forensic investigations. Human beings have genetically inherited characters. Genes located in the chromosome are the reason for this inheritance. The traits that are produced from such genes are likely to show strong association.
AIM AND OBJECTIVES:
To investigate the heritability of lip print and fingerprint pattern among south Indian population. To analyze the correlation between lip print and finger print pattern among parents and their off spring’s . The percentage of resemblance of lip print pat terns and fingerprints pat tern among parents and their offspring.
MATERIALS & METHOD:
The total sample size of the study includes 136 families in the South Indian population. For the sample size calculation, G*Power software was used with a power of 0.80. Informed consent was taken
from each of the participants. A thorough case history was recorded and detailed clinical examination was per formed. Materials were are A4 sheets, cellophane tape, dark colored lipstick, lipstick application brush, wett issue wipes, tissue papers, stamping ink pad, scissors were used.
RESULTS:
In this study, lip print and finger print pat terns were obtained among the family members categorized in 3 groups and statistically evaluated for the correlation and similarities of lip print and finger print pat terns, the predominant lip print pat tern in the entire study population was type II (branched grooves). The predominant fingerprint
pat tern in the entire study population was type II ( left loop) in both right and left index finger . Significant association between lip print pat terns among grandparents, parents and children were not iced in our study. Index finger prints pat tern showed positive correlation between family members.
CONCLUSION:
Further studies with large samples involving more study parameters may add to the findings of our study. A detailed analysis of different aspects of this evidence can be achieved by standardizing the methods and proposing the minimum matching points required. Besides al l this, the anthropological aspects of lip print pat terns and fingerprint pat terns should be practical, which can enable narrowing down of the investigation process
Correlation of Oral Health Status of Parents and their Children of Age Group 6 - 12 years using OHI-S, DMFT and Deft indices

Dental caries is the most prevalent disease among chi ldren al l
over the world. Despi te substant ial scient ific breakthroughs and the
fact that caries can be prevented, i t cont inues to be a major publ ic
heal th issue. Dental caries is influenced by a number of r isk variables
including age, gender, dietary habi ts, fluoride exposure, socioeconomic
status of parents , parental knowledge of oral heal th and oral
hygiene pract ices. As mo t h er s b e i n g r e s p o n s i b l e f o r c h i l d r e n ’ s h e al t h ,

METHODOLOGY:
A cross-sect ional study was conducted among 130 school
chi ldren aged 6 to 12 years and thei r mothers in Kelambakkam,
Chengalpat tu district after approval f rom Inst i tut ional Ethics
Commi t tee. Informat ion regarding demographic detai ls l ike name, age,
g en d e r , p a r e n t ’ s s o c i o -economic status (Head of the fami ly educat ion,
occupat ion and income) and maternal educat ion were recorded in the
pre-designed quest ionnaire. The socio-economic status was el ici ted
using Modi fied Kuppuswamy scale (2019). Dental caries and oral hygiene status of chi ldren and thei r mothers were recorded using deft ,
DMFT and OHI-S indices respect ively. Al l the data were tabulated and
analyzed using SPSS software 20.0.
RESULT:
The car ies prevalence in primary and permanent dent i t ion of the
chi ldren was 68.5% and 58.5% respect ively. P earson cor relat ion
analysis revealed that there is a significant posi t ive cor relat ion
between chi ldren and mother ’ s caries status (p = 0.0001) and oral
hygiene status (p = 0.0005). Children from lower socioeconomic status
had higher dental caries experience in primary and permanent
dent i t ion, as wel l as poor oral hygiene , when compared to chi ldren
from upper socioeconomic class. However, only dental car ies in the
primary dent i t ion (p = 0.015) and oral hygiene status (p = 0.0008)
indicated stat is t ical ly significant dif ferences. Lower caries experience
in the primary dent i t ion and bet ter oral hygiene status were
signi ficant ly associated to higher maternal educat ion, but there was no
such associat ion in the permanent denti t ion .
CONCLUSION:
Oral heal th status in 6 to 12 year old school chi ldren was found
to be cor related to mother ’ s oral health status, socioeconomic status of
parents and maternal education
A Cross Sectional Comparative study of Tooth Print as a Biomarker for Personal Identification in Normal and Fluorosed Teeth Surface
No full textAIM OF THE STUDY:
The aim of the present study is to analyse and assess the enamel rod end patterns for personal identification in normal healthy teeth and fluorosed teeth.
MATERIALS AND METHOD:
The present study comprises of two groups. Group I – fluorosed teeth (case group) and Group II – Normal teeth (control group). Age groups: 20 – 30 years, 30 – 40 years, 40 – 50 years. Each group comprises of 30 males and 30 females. 360 samples collected from 120 participants were considered for the analysis of tooth print pattern. The maxillary central incisor, canine and first premolar were selected. Enamel rod end pattern was recorded using acetate peel technique and analyzed using Verifinger® standard SDK version 11.1 software
RESULTS:
In the present study we have recorded and observed the tooth print pattern in fluorosed teeth and compared with normal tooth. Unlike the normal teeth which have a complete pattern, the fluorosed teeth showed an variation from complete to incomplete or inter-rupted pattern in our study. The difference in obtaining the enamel rod end patterns between normal and fluorosed teeth is statistically significant in central incisor and canine with p value 0.005 and 0.031 respectively but not in premolars where the p value is 0.06. The difference in obtaining the enamel rod end patterns between the age groups is not statistically significant with any of the teeth with p value 0.9 for central incisor and canine and with p value 0.43 for canine. The difference in obtaining in enamel rod end patterns between the gender is statistically significant among central incisor, canine and premolar with p value 0.006, 0.023, 0.022 respectively.
CONCLUSION:
Forensic odontology plays a very significant role in identification of deceased individuals based on the mortal remains of dental structures. Tooth print as a biomarker for personal identification is a recent evolving forensic concept. The technique is very simple and identification is based on the enamel rods end patterns on the outer surface of tooth. In the present study we have made an attempt to study the tooth print pattern in fluorosed teeth and have compared with the normal teeth. In our study we found a very unique complete to incomplete or interrupted tooth print pattern in fluorosed teeth in addition to the complete pattern. The application of these tooth print pattern as a reliable biomarker for personal identification requires further studies with larger sample size involving the entire dentition as well as studying all the surfaces of a single tooth
