Summary
Age estimation using the tooth coronal index (TCI) from dental radiographs is a precise and inexpensive method. This study validated TCI for age determination in Indian adults using mandibular teeth.
Area of Science:
- Forensic Odontology
- Radiographic Age Estimation
- Dentinogenesis
Background:
- Age estimation is crucial in forensic and clinical contexts.
- Tooth coronal index (TCI) reflects age-related changes in pulp cavity size.
- Secondary dentin deposition reduces pulp cavity dimensions with age.
Purpose of the Study:
- To establish age estimation for Indian adults using TCI.
- To analyze radiographs of mandibular first molars and second premolars.
- To validate the coronal pulp cavity index for age assessment.
Main Methods:
- Utilized 400 intraoral periapical radiographs of mandibular second premolars and first molars.
- Included participants aged 20-60 years, both genders.
- Employed Pearson's correlation coefficient (r) for age and TCI analysis using SPSS.
Main Results:
- Strong negative correlations found: r = -0.865 (premolars) and r = -0.850 (molars).
- Developed regression equations for age prediction.
- Achieved low mean errors: 6.72 months (premolars) and 9 months (molars).
Conclusions:
- TCI provides a precise, non-invasive, and cost-effective method for age estimation.
- Radiographic analysis of mandibular teeth is effective for age determination.
- The TCI method is suitable for application in Indian adult populations.

01:11Oral Cavity

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...

01:24Nose and Nasal Cavity
12.3K
The nose is composed of an observable exterior segment (external nose) and an internal segment within the skull known as the nasal cavity (internal nose). The external nose, visible on the face, consists of a framework of bone and hyaline cartilage enveloped in skin and muscle and lined with a mucous membrane. This structure is supported by the frontal bone, nasal bones, and maxillary bone and is supplemented by a cartilaginous framework comprising the septal nasal cartilage, lateral nasal...

01:06What are Estimates?
8.9K
It isn't easy to measure a parameter such as the mean height or the mean weight of a population. So, we draw samples from the population and calculate the mean height or mean weight of the individuals in the sample. This sample data acts as a representative measure of the population parameter. These sample statistics are known as estimates.
The estimate for the mean of a sample is denoted by ͞x, whereas the mean of the population is designated as μ. Further, parameters such...

Aging is a complex biological phenomenon influenced by various processes that affect cellular and systemic functions. Several prominent theories attempt to explain its mechanisms, highlighting cellular limitations, oxidative damage, and hormonal changes as central factors in aging.
Cellular Clock Theory
The cellular clock theory posits that the human lifespan is closely tied to the finite capacity of cells to divide, a phenomenon governed by telomeres, which are protective caps at the ends of...

01:28Standing Waves in a Cavity
1.5K
A household microwave and lasers are examples of standing electromagnetic waves in a cavity. When two conducting metal plates are placed parallel at the nodal planes, it creates a cavity where standing waves are formed. The cavity between the two planes is analogous to a stretched string held at the points x = 0 and x = L. Here, the distance 'L' between the two planes must be an integer multiple of half of the wavelength. The wavelengths that satisfy this condition are given by:

01:26Masonry Cavity Walls
1.5K
Cavity walls feature a hollow space between the outer and inner wythes, connected only by corrosion-resistant metal ties. When water seeps through the outer wythe, it descends within this cavity, intercepted by flashing and eventually exiting through weep holes. To enhance moisture resistance, the inner wythe's cavity side often receives damp-proofing, doubling as an air barrier. The cavity can also house insulation to mitigate heat transfer.
