Insights
Lip print patterns, unique to individuals, aid personal identification. The
Area of Science:
- Forensic Odontology
- Human Identification
- Dermatoglyphics
Background:
- Lip print patterns exhibit unique characteristics for each individual.
- These unique patterns are valuable for personal identification purposes.
- Previous research has established the basis for lip print pattern classification.
Purpose of the Study:
- To investigate the prevalence of various lip print patterns in children.
- To analyze the distribution of lip print patterns based on gender.
- To compare lip print pattern distribution across different racial groups.
Main Methods:
- A cross-sectional study involving 300 children was conducted.
- Participants were recruited from the Dental Outpatient Department of Kanti Children's Hospital, Nepal.
- Digital photography was employed to capture lip print images.
Main Results:
- 'Long vertical' (Type I) lip prints were the most frequent (41%).
- 'Unspecified' (Type V) lip prints were the least frequent (2.7%).
- Significant gender-based differences were observed for Type I (males) and Type IV (females) patterns. 'Type I' was common in both Caucasian and Mongolian children.
Conclusions:
- The 'Long vertical' (Type I) pattern is the most prevalent among children studied.
- All lip print pattern types, as per Suzuki and Tsuchihashi classification, were observed.
- Lip print analysis offers a potential tool for identification in pediatric populations.
Background:
Lip print patterns are unique in every individual. The uniqueness of lip print pattern assists in the personal identification. The objectives of the present study were to study the different lip print patterns among the children visiting Kanti Children's Hospital, and to compare the distribution of lip print patterns based on gender and race.
Methods:
A cross-sectional study was conducted among 300 children visiting the Dental Outpatient Department of Kanti Children's Hospital, Kathmandu, Nepal. Convenience sampling method was used to choose the study subjects. Digital photography method was used to record the image of lips.
Results:
The study showed 'Long vertical' (Type I) as the most frequent (41%) type of lip print pattern, whereas 'Unspecified' (Type V) was the least frequent (2.7%) type. Prevalence of 'Type I' pattern was significantly higher in males as compared to females (p=0.007) whereas prevalence of 'Type IV' pattern was significantly higher in females as compared to males (p=0.006). 'Type I' pattern was the commonest lip print pattern among both Caucasians and Mongolian, whereas 'Type V' (2%) and 'Type IV' (3.7%) were the least common lip print patterns in Caucasians and Mongolian children respectively.
Conclusions:
'Long vertical' (Type I) was the most common lip print pattern among the children visiting the Dental Outpatient Department of Kanti Children's Hospital, Kathmandu, Nepal. Nevertheless, in higher or lesser numbers, all kinds of lip print patterns as described by Suzuki and Tsuchihashi were seen in the study population.

The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.

01:15Teeth
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...

The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...
