Chronic Periodontitis Subclassification
- Localized Periodontitis - less than 30% @ mouth - attachment & bone loss
- Generalized Periodontitis - more than 30% @ mouth - attachment & bone loss
- Mild Pdtts - peridontal destruction @ not more than 1-2mm clinical attachment loss
- Moderate Pdtts - periodontal destruction @ 3-4mm attachment loss
- Severe Pdtts - periodontal destruction @ 5mm or more attachment loss
TemporoMandibular Disorder (TMD)
clinical problem that involves
1. TMJ
2. Masticatory Muscle
3. Associated structures
characterized by
1. Pain @ TMJ or Muscle of Mastication, Periacular Area
2. Limited Motion of Mandibular Range
3. TMJ Sounds during Jaw Function
Infection
- Microbes Proliferate @ Host Body
- General + or Local Defensive Pathological Rxn -> INDUCED
Etiology of Infx (Infx @ Haitiㅆㅂ년아ㅏ - HAOTI)
- Hematogenous Infx
- Adenogenous Infx
- Odontogenic Infx
- Traumatic Infx
- Iatrogenic Infx
Porcelain-Fused-to-Metal Crown (PFM)
- Dental Crown used to restore + protect a weakened tooth
- Main Components are
- Metal base
- Layer of porcelain on top
Bechet’s Disease
- Mouth-Eye-Genital Syndrome (눈코좆)
- Common @ 20-40岁 (男生!!))
- RAU or RAU-like Dx.
Symptoms (Behcet’s - GESR !! bacot geser lu WKWKW)
- Genital Ulcers
- Eye Damage
- Skin Lesion
- Recurrent Oral Ulcers
Frey’s Syndrome
Damage to or near Parotid Glands and From Damage to Auroculotempular N.
Happens due to a MISCOMMUNICATION between nerves that control SWEATING and those that control SALIVATION (production of saliva) after a previous injury or surgery in the area.
Dental Caries
- Infx. Microbiological Dx.
- Dental Caries results in
- Localized Dissolution
- Destruction of Calcified Tissue @ Teeth
Block Nerve Anesthesia / Nerve Block Anesthesia**
Managing Orofacial Pain without distorting anatomy of wound + without using narcotics
BNA (PAIN)
1. Posterior Superior Alveolar N. 🚫
2. Anterior Palatine N. 🚫
3. Inferior Alveolar + Lingual + Buccal N. 🚫
4. Nasopalatine N. 🚫
Chronic Periodontitis
- Bacterial Infx. of ALL parts of PERIODONTIUM (Bone, Cementum, Gingiva, Periodontal Ligament)
- IRREVERSIBLE - not the outcome of Gingivitis
- Usualy in Adults - Slow Progression
- 95% - Most Popular
- Clinical Manifestation - Bleeding, Bad Breath, Microbial Plaque, Periodontal Pockets (Deep, Suppuration)
Le Fort I Fracture (Low Maxillary Fracture @上 Lvl. 🦷)
- Maxilla is separated from the rest of Skull (Pterygoid Plates and Nasal and Zygomatic Structures)
- Occurs along Horizontal Line @ 上 Lvl. 🦷
- Because of Trauma - Forceful Blow to Face, Accidents, Fall
Le Fort II Fracture (Pyramidal Fracture @ Nasal Bone Lvl. )
- Fracture separates entire Midface from rest of Skull
- Occurs from Nasal Bones to Bones @ Eye Sockets (Orbits)
- Because of Trauma - High-Impact injury
Le Fort III Fracture (Craniofacial Disjunction @ Orbital Lvl. )
- Fracture separates entire Midface and Upper face (including nose, cheek, eye socket, bones surrounding them) from rest of Skull
- Occurs from Nose through Eye Sockets (Orbits) and continue to sides of Face
- Because of Trauma - Severe Trauma, Significant Falls
Ideal Normal Occlusion**
Proper Alignment and Positioning of 🦷 when Jaws come together during activity of Mandible
Individual Normal Occlusion
Alignment and positioning of their 🦷, while still functioning well, may have minor variations or deviations that are considered within the normal range for that person.
Pulp Cavity or Dental Cavity
- Cavity that contains
- Tissue
- Blood Vessels
- Nerves - Continuous with Periodontal Tissue thru Root Canal + Apical Foramen
Crown
- Caps placed @ top of damaged teeth
- Used to Protect, Cover, and Reshape (IF fillings dont solve the problem)
- Can be made of Metals, Porcelain, Resin, Ceramic
- Require good oral hygiene
Fundamental Principle of Cavity Preparation
- Remove ALL defects
- Conserve ALL healthy issue
- Locate Margins of Restoration as Conservative as possible
- Form Cavity so tooth withstand Occlusal (biting)
- Forces without Fracture and Displacement
- Allow for Esthetic and Functional Restoration - Give Protection to Dental Pulp
- Pay Attention to Systemic Dx.
Recurrent Aphthous Ulceration (RAU)/ RAS/ROU
- Common Ulcerative Lesion of Oral Cavity
- Recurrent, Painful
- 3 types: Minor, Major, Herpetiform
- Cause pain on Eating, Swallowing, Speaking
Calcified Tissues
- Dentin - yellowish white tissue, form bulk of tooth
- Enamel - brittle white tissue, head, covers crown of the tooth
- Cement - unusual form of bone that covers root of tooth
Impacted Tooth
- Tooth that fails to Erupt to Dental Arch within the Expected Developmental Window
- Caused by (ADE)
- Adjacent Teeth
- Dense Overlying Bone
- Excessive Soft Tissue/Genetic Abnormality
Fixed Bridge
- False Tooth (Pontic) that is held by Abutment Teeth @ either side of gap
- Typically made from Porcelain
- 4 Main Types (TCM-I)
- Traditional
- Cantilever
- Maryland
- Implant-supported
