Summary
Palatal rugae patterns in Indonesians are unique and predominantly line, sinuous, and curve shapes. These unique palatal rugae (PR) offer supplementary forensic identification data when primary methods are limited.
Area of Science:
- Forensic Odontology
- Anthropology
- Human Identification
Background:
- Palatal rugae patterns offer complementary forensic identification data.
- Useful when primary identifiers are limited or for population differentiation.
Purpose of the Study:
- Identify palatal rugae patterns in a modern Indonesian population.
- Compare findings with previous studies.
- Assess suitability for forensic applications.
Main Methods:
- Analyzed 100 archival dental casts (47 male, 53 female) from Indonesian patients.
- Recorded age, ethnic/geographic origin.
- Applied Trobo classification for rugae shape analysis.
Main Results:
- Predominant rugae shapes: line, sinuous, and curve (approx. 83%).
- All recorded individual palatal rugae patterns were unique.
- Consistent with slow rugae loss (1 per 15 years post-adulthood).
Conclusions:
- Palatal rugae patterns provide valuable supplementary identity information.
- Requires antemortem data for effective use.
- Recommends 3D oral/dental scanning and pattern recognition for data retention and analysis.

The oral cavity, or the mouth, is a complex structure in humans that plays a vital role in our day-to-day lives. Its role is not only in chewing and swallowing food; it also plays a role in speech and facial expressions.
Teeth: The teeth are the hardest structures in our bodies. Humans have two sets of teeth throughout their lifetime: deciduous (baby) teeth and permanent teeth. Each tooth consists of several parts: the crown (visible part), the root (embedded in the jaw), enamel (hard outer...

01:27Histology of the Small Intestine
4.8K
The small intestine exhibits a unique histological structure that significantly enhances its function in digestion and nutrient absorption. These structures include circular folds, villi, and various specialized cells that collectively facilitate the digestion of food.
The intestinal lining features transverse folds called circular folds, each housing fingerlike projections known as intestinal villi. These villi are covered by a layer of simple columnar epithelium, also referred to as...

01:28Development of the Oral Microbiota
37
The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...

01:15Teeth

The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
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...

00:49The Tongue and Taste Buds
42.2K
The surface of the tongue is covered with various small bumps called papillae, which either distribute what has been ingested (filiform papillae) or contain the sensory taste (or gustatory) receptor cells (fungiform, circumvallate, and foliate papillae). Embedded within each taste-related papilla are the taste buds—clusters of 30 to 100 gustatory receptor cells.

01:26Assessment of the Mouth
1.5K
A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.
