then - mechanical irritants cause of perio, treat by scaling to remove depositsnow- bacterial pathogens overwhelm host's immune response, now control pathogenic bacteria | Etiology: |
then- complete calculus removal is necessary for healingnow - remove all clinically detectable deposits | Calculus removal |
then - deeply imbedded in cementum, had to root plan to glassy smoothnow - toxins loosely associated with outer layers of cementum, easily removed with light instrumentation or ultrasonic acoustic turbulence | Bacterial endotoxins |
then- subgingival instrumentation limited to rootsnow - instrument the entire pocket =root, pocket space, soft tissue wall, adherent plaque removed from tooth, unattached plaque removed from pocket space, ultrasonic instruments of choice for unattached plaque, lavage beneficial | Treatment of pocket environment - |
then skilled clinician can detect allnow - skilled clinician effective 50% on residual calculus | Detection of residual calculus |
then - too technically difficult beyond 5 mmnow - closed debridement as successful as surgical debridement at all levels of disease | Closed debridement |
then- limited to supra usenow- as effective as hand scaling, detoxify root surface | Ultrasonic instrumentation |
then- all root surfaces within a pocket MUST be root planednow-extent of instrumentation necessary to achieve tissue health varies, when tissue does not respond then root plane | Extent of subgingival instrumentation |
| >Instrument tooth surface - clean and smooth -Remove calculus - explorer detection, smooth -Biologically acceptable root surface -Soft tissue response >Disrupt plaque -Reduce microorganisms below the client's threshold >Restore gingival health -Monitor plaque control -Decrease inflammation -Clinician maintain healthy microbial environment -Create environment client can maintain -Create maintainable pockets -Sufficient time for healing >Create an environment client can maintain -Inform client of treatment limitations | Goals of Instrumentation |
- mechanical instrumentation of the crown & root surface of the teeth to remove plaque, calculus, and stainsOutcome assessment - all clinically detectable calculus removed | Scaling |
- definitive treatment procedure designed to remove cementum or surface dentin that is rough, impregnated with calculusRationale Smooth root surface so as to decrease surface where plaque & calculus may attach Outcome - instrument all of root surface, NOT glassy smooth "Rifled" roots | Root planing |
| - supra/subgingival debridement & deplaquing with minimum of tooth structure removal Removal of foreign material including biofilm, its by-products, toxins, calculus, Crown, root, pocket space, pocket wall, underlying tissue Conserve tooth & root surface Combination of hand & ultrasonic instrumentation | Debridement |
- preventive procedure to remove local irritantsBiofilm, calculus, stain | Prophylaxis |
- polishing agents to remove stains & plaqueSelective polishing | Coronal polishing |
Mechanical disruption of non-attached subg. Biofilm & by-products from sulcusRe-evaluation appt & MTX | Deplaquing |
| -Arresting progress of periodontal disease by removing: Biofilm Biofilm retentive calculus -Create an environment that assists in maintaining tissue health Increase the effectiveness of patient self-care Eliminate areas of biofilm retention -For a periodontally involved tooth, the primary pattern of healing is through the formation of a long junctional epithelium Maybe also gingival recession | Rationale for Periodontal Debridement |
- gross scaling leaves behind partially removed deposits that are rough, irregular and covered with bacteria As the marginal tissue shrinks, it closes off the entrance to the pocket, providing a protected environment and the microorganisms continue to grow | Proliferation of microorganisms |
- incomplete calculus removal allows the gingival margin to tighten around the tooth, prevents drainage of bacterial toxins = can develop into perio abscess. Medically compromised and clients with deep infraboney pockets are at risk | Abscess formation |
-Tight marginal tissue at subsequent appointments | Difficult instrumentation |
- removable of visible deposits combined with improved appearance of gingiva may influence the client to forego future treatment "What they can't see can hurt them" | Decreased client motivation |
-Multiple appointments in which the entire mouth is instrumented ... "I thought you cleaned all of my teeth at the last appt.?" | Client frustration |
incomplete calculus removal/healing at the margin present problems:proliferation of microorganisms abscess formation difficult instrumentation decrease client motivation client frustration | Gross Scaling |
-treat as many teeth as you can treat thoroughly at one appointment-complete one sextant/quadrant same side of mouth -start with sextant and then move to quad *Start most infected quad OR area of client's chief complaint | Sextant/Quadrant |
| 1. Treat as much as you can in posterior sextant before moving on to the anterior teeth 2. Always scale one side of the mouth - increased client comfort, they can eat in comfort 3. Start in area with deeper pockets unless client has chief complaint concentrate another area 4. Divide posterior and anterior - different instruments instrument facial and lingual surfaces of posterior sextant before moving on | Sextant/Quadrant |
Scale entire mouth in 2 appointments scheduled 24 hours apart (medical model)2 week use of CHX mouth rinse Microorganisms do not have time to repopulate areas -Sextant scaling modified plan >>> clean sextant by sextant and then at the last appointment use ultrasonic on entire mouth | Full Mouth Disinfection |
| Instrument selection determined by: type and location of deposits probe =extent. Location and characteristics of clinical attachment loss explorer = determine amount, location and distribution calculus use curette for calculus detection to avoid switching back and forth supragingival calculus first with sickle subgingival next with curette OR ultrasonic = instrument entire pocket, begin coronally, ADAPT tip into interproximal areas | Sequence |

| Use thumb or index finger of non-dominant hand against instrument shank Concentrates stroke pressure against tooth surface Control working end throughout instrument stroke Advantages -concentrated stroke pressure for removal of tenacious subgingival deposits -creates a well controlled instrument stroke -reduces muscle strain and workload for the non-dominant hand Disadvantages Non-dominant hand cannot hold mirror | Stabilize Finger Assist |
Abnormal condition that occurs when vital dentin is exposed to the environmentPainful stimuli reach pulp and cause pain | Dental Hypersensitivity |
| Rapid onset ... Sharp, short, or transient pain Sharp pain ... Presents as chronic condition with acute episodes Short duration ... Cessation from pain upon removal of stimulus Respond to stimuli Discomfort that cannot be ascribed to any other dental problem Pain from something that would normally not cause pain | Characteristics of Dental Hypersensitivity |

Air syringe | Evaporation-dehydration of oral fluidsStimuli |
Alteration of osmotic pressure in tubules due to isotonic solutions of sugar and salt | Osmotic Stimuli |
Acidic foods, fruit drinks, sport drinks | Chemical Stimuli |
| -Primary cause are exposed dentin and open tubules -10% of developing teeth Cementum does not meet enamel -Abrasion, erosion, abfraction, dental caries, over instrumentation -Less common is loss of enamel exposing dentin -Soft tissue loss Gingival recession Periodontal surgery Aggressive tooth brushing -Stage is set by: Recession Loss of cementum Dentin exposure | Etilology of Dental Hypersensitivity |
-Covered by enamel on crown and cementum on root-Composed of fluid filled tubules, which become narrower in diameter as they extend from the pulp to the DEJ -Portals through which stimuli are transmitted to the pulp -Innervated with nerve fibers from the pulp chamber | Biology of Dentin |
-Innervated with nerve fiber endings that extend just beyond the dentinopulpal interface of the dentinal tubules-Odontoblasts extend their processes from the dentinopulpal interface about 1/3 through dentinal tubules -Nerves exhibit excitability like any other nerve to a stimulus | Biology of Pulp |
| Effects of OH Use of medium -->hard brush Aggressive toothbrushing Narrow band of attached gingiva Tight and short frenum Periodontal surgery Aging process Oral piercing Tooth fracture Facial orientation of tooth Excessive instrumentation in shallow sulcus NUG Perio surgery - crown lengthening Ortho movement Restorative procedures .... Crown preparation Metal oral jewelry, oral piercings Attrition, abrasion Dietary erosion from acids Brushing immediately after consumption of acids Gastric acids from morning sickness, self induced Abfraction Frequent use of abrasive stain removal products Root surface caries | Factors Contributing to Gingival Recession & Root Exposure |
-Cementum at cervical area is thin and subject to wear-Enamel and cementum do not meet -10% -Attrition, abrasion and erosion -Abfraction-Occlusal forces cause enamel rod fracture -Over-instrumentation - Improper stain removal | Loss of Enamel and Cementum |
Calculus formation: "protective" coveringSclerosis of Dentin: Mineral deposition within tubules as a result of traumatic stimuli (attrition or caries) Thicker highly mineralized layer of peritubular dentin (deposited within periphery of tubules) Sclerosis results in a smaller diameter tubule that is less able to transmit stimuli through tubule fluid | Natural Desensitizers |
| -Odontoblasts deposit dentin on the floor and roof of the pulp chamber, which decreases the size of pulp tissue over time Occurs only after teeth fully developed -Creates a "walling off" effect between the dentinal tubules and the pulp to insulate the pulp from dentin fluid disturbances caused by a stimulus -As aging occurs, secondary dentin accumulates, resulting in smaller pulp chamber | Secondary Dentin |
Formed in area where exposed dentin has been traumatized by a stimulus such as dental cariesSimilar to secondary dentin Insulates the pulp from dentinal tubule fluid disturbances | Tertiary Dentin/Reparative Dentin |
| Consists of organic and inorganic microcrystalline shavings of cementum, dentin Also contains tissue debris, odontoblastic processes and other microbial elements Temporary desensitization of teeth Teeth may become sensitive appx. 2-3 days after the appt. Plugs dentinal tubule orifice Smear plug, "bandage" Can dissolve by acids, disruption by ultrasonic, self-care Positive / negative effect - neg. may interfere with reattachment of periodontal tissues | Smear Layer |
| Stimulus at the outer aspect of dentin will cause fluid movement within the dentinal tubules, which signals the nerves in the pulp Dentinal tubules exposed Pain-producing stimuli present Initiate flow of lymphatic fluid within tubule Odontoblast and their processes act as receptor and transmit sensory stimuli Movement of tubular fluid cause nerve endings at pulpal wall to be stimulated and produce pain | Hydrodynamic Theory |
| 8-30% of adult population experiences hypersensitivity 20-30 years of age, peek Peek again @ 50 years Recession more prevalent among aged but dentin hypersensitivity is not-natural desensitization occur with aging Women report more pain then men Higher prevalence in perio patients Incidence and severity declines with advancing age due to the effects of sclerosis and secondary dentin Equally present in men and women BUT women report more frequently | The Sensitive Patient |
