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.

Summary

Denture stomatitis increases resilient liner surface roughness. All denture liners became rougher after 14 days of wear, regardless of oral tissue health, indicating material degradation over time.

Background:

Resilient liners are used in complete dentures to improve comfort and fit.
Denture stomatitis, an inflammation of oral tissues under dentures, can affect liner properties.
Surface roughness of denture materials is a critical factor influencing biofilm accumulation and oral health.

Purpose of the Study:

To evaluate the effect of denture stomatitis and duration of wear on the surface roughness (Ra) of resilient denture liners.
To compare the surface roughness changes in different types of resilient liners and acrylic resin control specimens.
To understand the relationship between oral tissue health and the physical properties of denture biomaterials.

Main Methods:

A randomized clinical trial involving 30 patients with complete dentures, with and without denture stomatitis.
Insertion of acrylic resin (control), silicone-based, and acrylic resin-based liners into dentures.
Surface roughness (Ra) measurements taken at baseline, and after 7, 14, and 21 days of prosthesis use.
Statistical analysis using three-way ANOVA and Student-Newman-Keuls test.

Main Results:

Patients with denture stomatitis exhibited significantly higher surface roughness (Ra) on their denture liners (P < .001).
All tested liner materials demonstrated increased surface roughness after 14 days of clinical use.
The increase in roughness occurred irrespective of the patients' soft tissue health condition.

Conclusions:

Denture stomatitis is associated with increased surface roughness of resilient denture liners.
Prolonged use of complete dentures leads to a progressive increase in liner surface roughness.
These findings suggest that material degradation and biofilm accumulation may be accelerated in patients with poor oral hygiene or compromised tissue health.
