Inlay **
indications :
- initial lesions
- replacing failed amalgams/composites
contraindications :
- cracked teeth
- wide isthmus/deep pulpal - esthetic concerns
Junctional Epithelium (JE)**
- Epithelium @ base of Gingival Sulcus
- calibrated periodontal probe is used to measure the probing depth of the gingival sulcus. The probing depth of the gingival sulcus, however, can be considerably different from the true gingival sulcus depth
Laceration
- A tear in the epithelial and subepithelial tissues
- Most frequent type of soft tissue injury
- Involve the external surface only, but others extend deeply into the tissue
Local Anesthesia***
reversible blocking of peripheral nerve conduction by the proper application of local anesthetic agents, temporary blocking a painful stimulus from nerve endings to the central nervous system, and not loss of consciousness
Localized moderate chronic periodontitis
Chronic separation of the periodontal tissue from the root by 3-4 millimeters of clinical attachment loss in less than 30% of sites as measured from the cementoenamel junction to the base of the probable pocket (gingival sulcus).
Major Aphthous Ulcer (MjAU)
- It is termed MjAU and MjRAS
- Site: occurred on mpvable non keratinizing oral surfaces, such as the corner of the mouth, and soft palate, uvula
- Lesion: single, 10~30 mm in diameter and the ulceration is deeper, with clear margin, a little hard on the bottom
Minor aphthous ulcer (MiAU)
- The most common type, 80% of the RAU
- Most MiAU occur in the non-keratinized part of the
membranes - Number and size: single or multiple, 5~10 mm (Diameter)
- Painful
- Shallow and round to oval
Malocclusion
misalignment of teeth and/or incorrect relation between the maxilla and mandibula.
Nevoid Basal Cell Carcinoma Syndrome
- bifurcation of rib
- lamellar calcification of the falxcerebri
- multiple nevoid of the skin
- multiplekeratocysts
Normal Pulp
- Asymptomatic and produces a mild to moderate transient response to thermal or electrical stimuli.
- The response subsides almost immediately when the stimulus is removed.
- No painful response to percussion or palpation.
- Radiographs reveal no calcification or tooth resorption, and the lamina dura is intact.
Obstructive Asphyxia
pathological changes caused by lack of oxygen in respired air, resulting in hypoxia and hypercapnia.
Caused by :
- foreign bodies
- collapsed mandibular fracture
- grossly displaced and swollen tissues
- hematoma
- occluding edema from fractured larynx or trachea
Odontoblast Phenotype
Large columnar cells arranged in an epithelioid sheet along the junction between dentine and pulp, all the way down to the root apex
Odontogenic infection
- infection that originates within a tooth or in the closely surrounding tissues.
- It is one the commonest diseases in origin for oral and maxillofacial region and symptoms with the infections in other places.
- The common local signs include redness, swelling, high local temperature, pain and dysfunction
Onlay
- cover all the occlusal surface
- inset into the cavity to recover the shape and function of tooth
Osseointegration
a direct, structural and functional connection between ordered, living bone and the surface of a load-carrying implant
