Abstract
BackgroundTo assess the correlation between different dermatoglyphic patterns with the terminal planes in deciduous dentition.Material and Methods300 children who are 3-6 years old with complete primary dentition were recruited and the pattern of molar terminal plane was recorded in the proforma. Finger prints of the distal phalanges of these subjects were recorded using ink and roller method and were analysed for the finger print pattern by a forensic specialist. The pattern were classified based on classification given by Galton. The finger ridge counts were also measured.ResultsUlnar loop pattern was the most predominant dermatoglyphic pattern. Absence of arch pattern in ring and little fingers of left hand and higher ridge count in left little finger when compared to the right hand were related to Mesial step. Presence of whorl pattern in both right and left middle finger and higher total finger ridge count in left hand when compared to the right hand were related to distal step. Flush terminal plane was related to absence of arc pattern in ring finger of left hand.ConclusionsDermatoglyphics can be used as a non invasive analytical tool to predict the terminal plane in primary dentition. Key words:Dermatoglyphics, terminal planes, primary dentition.
Highlights
The terminal plane of the second molars in the primary dentition have a significant role in determining the occlusion of the succedaneous dentition [1,2]
A significant reduction in arch pattern in the ring finger (p=0.023) and a significant rise in loop pattern in the little finger (p=0.008) were noticed in left hand while the right hand showed an increase in whorl pattern in the ring finger that was not significant (p=0.436)
The mean total finger ridge count in the left hand, right hand and both hands showed significantly lesser count in mesial step when compared with other terminal planes (p
Summary
The terminal plane of the second molars in the primary dentition have a significant role in determining the occlusion of the succedaneous dentition [1,2]. This study was aimed to assess the possible correlation between dermatoglyphics and the different terminal planes in primary dentition. To assess the correlation between different dermatoglyphic patterns with the terminal planes in deciduous dentition Material and Methods: 300 children who are 3-6 years old with complete primary dentition were recruited and the pattern of molar terminal plane was recorded in the proforma. Absence of arch pattern in ring and little fingers of left hand and higher ridge count in left little finger when compared to the right hand were related to Mesial step. Presence of whorl pattern in both right and left middle finger and higher total finger ridge count in left hand when compared to the right hand were related to distal step. Conclusion: Dermatoglyphics can be used as a non invasive analytical tool to predict the terminal plane in primary dentition
