Study Notes
Oral Examination
- A systematic oral examination is essential for routine dental checkups and for individuals with dental issues.
- Inspect the entire oral mucosa, and any ulcers lasting over three weeks require further investigation.
- Quickly assess periodontal condition using a periodontal probe, pockets exceeding 5mm warrant a thorough assessment.
- Chart the teeth present and examine each tooth for caries and restorations.
- Examine the occlusion, including the patient's bite, the path of closure, prematurities, and displacements.
- Evaluate teeth wear.
Radiology and Radiography
- Radiography is the process of creating radiographic images, while radiology involves the interpretation of these images.
- Radiographic images arise from the varying absorption of X-rays by different tissues.
- Radiographic quality depends on tissue density, beam intensity, emulsion sensitivity, processing techniques, and viewing conditions.
Intra-Oral Views
- Intra-oral radiographs are created using a stationary anode (tungsten) and direct current.
- Direct-action dental film (high detail) utilizes either D or E speed film, with E speed being twice as fast as D, thus requiring less radiation exposure for the patient.
- Rectangular collimation minimizes unnecessary radiation exposure to tissues.
- A periapical radiograph captures the entire tooth, the root, and surrounding periapical tissues
- Two primary intra-oral techniques: Paralleling technique and Bisecting angle technique.
Sedation and Behavior Management
- Sedation may be necessary for anxious children to improve cooperation, manage gag reflexes, or to supplement local anesthesia (e.g. for difficult extractions).
- Oral, intramuscular, intravenous, per rectum, and inhalation methods are used for sedation, each with its own indications and risks.
- Nitrous oxide/oxygen mixture is commonly employed for sedation in children.
- Introduce the "happy air" separately to the dental treatment.
- Encourage parental presence to provide comfort and facilitate consent adjustments if needed, but ideally, parents should act as "silent helpers."
- General anesthesia should be reserved for dental procedures when other management methods are unsuitable, and alternative strategies and risks should be discussed with parents.
Tooth Structure Abnormalities
- Enamel development involves an organic matrix followed by mineralization.
- Disruptions in this process can lead to enamel hypoplasia and hypomineralization.
- Hypoplasia: Pitted, grooved, or thinned enamel due to matrix formation disturbance.
- Hypomineralization: Hypocalcification resulting in opaque, white, yellow, or brown enamel.
- Most enamel disturbances produce both hypoplasia and hypomineralization, but usually, one predominates.
Etiological Factors for Enamel Disturbances
- Localized causes: Infection, trauma, irradiation, and idiopathic factors.
- Generalized causes:
- Environmental: Pre-natal (e.g. rubella, syphilis), neo-natal (e.g. prolonged labor, premature birth), post-natal (e.g. measles, congenital heart disease, fluoride, nutritional deficiencies).
- Hereditary: Affecting only teeth (e.g. amelogenesis imperfecta) or accompanying systemic disorders (e.g. Down syndrome, tuberous sclerosis).
Chronological Hypoplasia
- Enamel hypoplasia related to the extent of tooth formation at the time of the insult.
- Affects tooth number 2 more prominently near the incisal edge compared to teeth 1 and 3 due to its later formation.
Molar Incisor Hypomineralization (MIH)
- Etiology is currently unknown.
