Chairside Dental Assisting Unit 2 Periodontal Charting - Answer -ensures where patients gums/tissues is Define: marginal gingiva, attached gingiva, and alveolar mucosa - Answer -Gingival margin: the area around neck; collar around mouth: where you floss. Around necks of teeth where enamel meets cementum its marginal gingiva(curved) Attached gingiva: directly attached to bone when healthy. Lining of cheek and lips is alevolar mucosa: free not attached to bone. Peritnized tissue is tough What happens to marginal gingiva when you have periodontal disease? - Answer -When you have periodontal disease: the tissue resedes. Margin is straight not curved What is the process of periodontal probing? - Answer -Insert at distil line angle. Parallel to line angle of tooth. Walk 1-2mm distil until contact. Walking stroke 1-2 mm to mesial contact Record 6 numbers per tooth. 3 on buckle/facial and 3 on lingual distal line then to mesial for every tooth. PSR: spot probing Periodontal Chart information: - Answer -Each probing box Box has 3 section: distil, facil, mesial readings. Red/blue pen. Blue for 1-3 readings. Red readings 4 or higher. Bleeding points are writen with red. With dot or star above or too right of reading. If bleeding you star that or dot that number. Recession: tissue moving away from margin Mast. Mucosa: free lining in gingiva Farcation involvement (how many roots): If so much bone lose in recession in map: roots are visible : farcation (bifarcasion for mandibular an trifarcation for maxillary) can take probe and go through Can put farcation invovlement 1. maxillary molars have 3 and premolars have 2. blocked out if no farcation (single rooted tooth) Maxillary molars have 3 roots and mandiublar have 2 roots Periodontal probes - Answer -used to locate and measure the depth of periodontal pockets. tips can be color coded to make the measurements easier to read. tapered to fit into the gingival sulcus/has a blunt or rounded tip. Six measurements are taken and recorded for each tooth. available in many designs It's a three unit bridge PFM bridge outline the crown of the tooth and facial occlusal and lingual and hatch lingual surface. This bridge needs to be done (bc red ink) There is an X tooth needs to be extracted is one diagnol line. : the X is blue that extracted Join them to show that this is a bridge Full Gold Crown - Answer -Hatched on facial lingual and occlusal Really expensive today, rarely see it. Implant - Answer -longer longevity then crown; implant down the root of tooth, you hatch it horizontal lines through it to indicate implant (the root) Drifting - Answer -area where it is drifting, wherever it is drifting draw an arrow that way Rotated - Answer -if rotated not drifting, then draw a circle in that direction Periodical abscess - Answer -circle at the apex of the tooth (root of the tooth) Root canal - Answer -one line down the root of tooth impacted/unerupted - Answer -circle impacted tooth; not yet in Missing/extracted - Answer -X, can be drawn through it To be extracted - Answer -needs to be extracted, one line through it, when completed draw another line to create X. Stainless steel crown - Answer -put SS on occlusal surface shell filled with cement to put on tooth Sealant - Answer -- Put one S, indicate teeth has sealants: take composite material that is not filled, and filling the deep pits and fishers G. V. Black's Cavity Classification - Answer -used to describe location of decay/ and or condition universal to all dentists/ easy for one dentist to read another dentist's records Black described/ developed 5 cavity classes a 6th added at later date Cavity classification 1 - Answer -any decay in pit and fissures (predominately posterior teeth) areas we generally seal--> just occlusal surface Cavity classification 2 - Answer -MOD (medial, occlusal, distal) moved on and passed the marginal ridges extended cavity classification I (pit and fissure with inter proximal involvement) Cavity classification 3 - Answer -anterior tooth (involves mesial and distal) involves the proximal surfaces medial and distal: no incisal involvement Cavity classification 4 - Answer -inter proximal of anterior; now have incisal involvement Cavity classification 5 - Answer -smooth surface: down by facial gingival margin or lingual gingival margin Cavity classification 6 - Answer -have decay on cusp tips (because of grinding and sports drinks) Cavity wall - Answer -internal surface of prepared tooth external wall - Answer -M, D, F, L surface of prepped tooth extending to external tooth internal wall - Answer -walls that do not extend onto external surface axial wall - Answer -know: axial wall: runs parallel to pulp long axis of tooth; internal/runs parallel to pulp or long axis of tooth
