Teeth

Teeth

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...

Assessment of the Mouth

Assessment of the Mouth

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.

Area of Science:

Periodontology
Dental Prognosis
Risk Assessment

Background:

Tooth-level prognostic systems are crucial for planning treatment and assessing risk in periodontally involved teeth.
The Miller-McEntire index previously outperformed other systems but had limitations.
This study developed and evaluated a modified system, the Periodontal Risk Score (PRS), to address these limitations.

Purpose of the Study:

To develop and evaluate the prognostic performance of the Periodontal Risk Score (PRS).
To create a more effective tool for predicting tooth loss due to periodontitis.

Main Methods:

Retrospective data analysis from patients receiving periodontal treatment at a university setting.
Utilized univariate and multivariate Cox proportional hazard regression models.
Analyzed prognostic capability for predicting tooth loss due to periodontitis (TLP).

Main Results:

The PRS successfully stratified TLP risk at baseline across different tooth types.
The index demonstrated excellent predictive capacity for TLP after controlling for maintenance, age, and sex (Harrell C-index of 0.947).
A total of 6762 teeth from 281 patients were followed for a mean of 22.6 years.

Conclusions:

The Periodontal Risk Score (PRS) shows excellent predictive capability for both anterior and posterior tooth loss due to periodontitis.
The PRS accurately predicts long-term tooth loss in a population treated by dental students and residents.
The study recommends using the PRS or similar systems for establishing tooth prognosis.
