Detecting Caries in Clinical Practice

In this section, the focus is on the clinical examination methods used to detect caries and non-carious defects in dental practice.

Visual Examination

• Visual examination is crucial for detecting caries.

• Conducted in a dry, well-illuminated field to enhance accuracy.

• Incipient carious lesions may disappear when wet, emphasizing the importance of a dry environment.

Tactile Examination

• Tactile examination involves using an explorer tool.

• Care must be taken to avoid iatrogenic cavitation.

• False positives can occur due to explorer tip catching on non-caries defects.

Radiographic Examination

• Radiographs are highly valuable for caries detection.

• Different stages of carious lesions are visible on radiographs.

• Lesions are often smaller radiographically than clinically due to mineral loss requirements for detection.

Transillumination

• Transillumination is a newer method for caries examination.

• Involves shining light through contact areas of teeth to detect shadows indicating carries or other defects.

Dentistry Technology and Examination

The discussion covers new technologies in dentistry such as laser fluorescence, digital imaging, fiber optic transillumination, quantitative light-induced fluorescence, and electrical conductance for caries detection. Specific examinations for amalgam restorations are also highlighted.

New Technologies in Dentistry

• Laser fluorescence, digital imaging, fiber optic transillumination, quantitative light-induced fluorescence, and electrical conductance are utilized for caries detection.

• These technologies offer better specificity according to research.

Amalgam Restorations Examination

• Unique features of amalgam restorations include a bluish hue due to leaching of corrosion products or underlying color.

• Proximal overhangs, marginal gaps or ditching are examined; minor issues may self-seal but significant ditching (>0.5mm) indicates replacement need.

• Voids, fracture lines, and budding fractures in posterior teeth are monitored closely.

Tooth Structure Erosion and Wear

This section delves into different types of tooth structure loss including erosion caused by acidic substances or gastric acid without bacterial involvement. It also discusses abrasion from mechanical wear and attrition due to functional contacts with natural teeth.

Tooth Structure Loss Types

• Erosion:

• Caused by acidic foods or beverages leading to chemical loss without bacterial involvement.

• Manifests as cupping on cusp tips of posterior teeth; can affect restorations' appearance.

• Abrasion:

• Pathologic wear from abnormal mechanical processes like toothbrush abrasion or crown grinding.

• Attrition:

• Occlusal wear from functional contacts with opposing natural teeth; distinct from abrasion involving artificial crowns.

Hypersensitivity and Treatment Planning

Hypersensitivity results from exposed dentinal tubules on root surfaces causing pain via fluid movement stimulation near the predentin. Treatment planning prioritizes addressing the patient's most critical needs first.

Hypersensitivity Causes

• Hydrodynamic Theory:

• Pain arises from fluid movement stimulating mechanoreceptors near predentin due to various triggers like temperature changes or air drying.

Treatment Planning Principles

Treatment Planning Phases

The video discusses the different phases of treatment planning in dentistry, ranging from urgent care to maintenance.

Urgent Phase

• Urgent phase addresses acute oral health needs, such as emergency patients experiencing pain, infections like abscesses, and swelling.

• Treatments in this phase include endodontics, extractions, and temporary restorations.

Control Phase

• Focuses on caries control by eradicating active oral diseases and managing risk factors contributing to these diseases.

• In operative dentistry, the emphasis extends to gum disease (periodontics) and promoting oral hygiene and a healthy diet.

Restoration Criteria & Preventive Dentistry

This segment delves into criteria for restoring a tooth and emphasizes preventive dentistry practices to avoid disease manifestations.

Restoring a Tooth Criteria

• Considerations for restoring a tooth include assessing the patient's caries risk level based on various factors like existing lesions and dietary habits.

• The lesion should extend to the dentin-enamel junction with cavitation present before restoration is necessary.

Preventive Dentistry

• Emphasizes preventing disease manifestations before they occur through remineralization of incipient lesions using fluoride.

• Recommends treating caries-prone pits and fissures with sealants as part of preventive measures.
