purpose for The Bass Method (sulcular)
most widely used; For all pt.s for dental biofilm removal adjacent to & directly beneath the gingival margin; for open embrasures, cervical areas beneath the height of contour of the enamel & exposed root surfaces; periodontal surgery;
adaptable to abutment teeth, under gingival border of F.P.D & orthodontic appliances
brush position forThe Rolling Stroke Method: (nonsulcular)
direct brush tips apically:max up & man down; place side of brush against attached gingiva; no 45 degree angle;

purpose for The Modified Stillman Method: (sulcular)
remove biofilm from cervical areas below height of contour & from exposed proximal surfaces; cleaning tooth surfaces & massage of the gingiva
purpose for The Charter's Method(nonsulcular)
the interproximal toothbrushing, used to stimulate marginal and interdental gingiva; to loosen debris and dental biofilm; following periodontal surgery; easily adapt to cervical areas below the height of contour of the crown and exposed root surfaces, for biofilm removal of abutment teeth and under the gingival border of a FPD and orthodontic appliances

direct relation, gingival damage, rounding
______ _______ exists between _______ ______ and the absence of end- ________
describe the stroke for Bass Method of brushing
Press brush filaments lightly into gingival sulculs and embrasures covering the gingival margin; vibrate back and forth with very short strokes without disengaging the brush; count at least 10 vibrations; reposition for the next group; repeat
Purpose for Rolling Stroke (nonsulcular)
Cleaning gingiva & removing biofilm/materia alba/ food debris
describe the stroke for the Rolling Stroke method
press lightly to flex filaments; when sides of filaments are pressed lightly against gingiva, gingiva will blanch; roll the brush slowly over the teeth; as the brush is rolled wrist is turned slightly; replace and repeat five times for each group of teeth
limitations for Bass Method
overeager brushers may brush too vigorously causing damage to the gingival margin; 45 degree angle requirement may be difficult for some pts.; pts may tend to seperate methods, performing rolling stroke first, instead of combining the two for complete sulcular brushing;
disadvantages of Modified Bass Method
brush not positioned into sulcus properly, or too much time spent trying to place brush tips into sulcus properly; injury to gingival margin from constant repositioning; premature sulcular brushing due to premature rolling stroke
brush position for Bass Method
Direct the filaments apically, Max up & Man down; position the sides of the filaments parallel with the long axis of the tooth; turn the brush head toward gingival margin at a 45 degree angle; directing brush tips into the sulcus
brush postition for the Stillman Method
place filaments partialy on gingiva & partialy on cervical areas; slightly directed apically; 45 degree angle; tissue blanching occurs with slight pressure on the gingival margin
describe the stroke for the Stillman Method
rotate the handle slightly causing the brush to go in a circular motion; brush ends maintaining position on the tooth surface; repeat several times for each group of teeth
position of brush for Modified Stillman Method
direct filaments apically, max. up and man. down; place side of brush on the attached gingiva; plastic portion of brush head should be level with occ/inc plane
strokes for Modified Stillman Method
same as stilman w/ rolling stroke included
limitations for Stillman Method
improper placement of bristles may cause tissue laceration; may ineffectively remove biofilm at the gingival margin cause by doing the rolling stroke too soon during brushing
brush position for Charters Method
direct filaments at a 45 degree angle; point toward incisal edge or occlusal; max. down; man. up; forcing tips into the interproximal area causing sides of bristles to come in contact with the gum margin for an ideal massage
limitations for Charters Method
brush ends do not engage the gingival sulcus to remove subgingival bacterial accumulations; brush placement limited in some areas, requires high digital dexterity
strokes for Charters Method
press lightly to flex filaments, forcing tips between the teeth; press sides of filaments against the gingival margin; vibrate brush gently but firmly, maintaining contact with tooth surface; count to 10 as you vibrate with a rotary motion; repostion the brush and repeat

procedure for use of power toothbrush
select brush with soft end-rounded filaments; select dentifrice with minimum abrasivity; place a small amount of dentifrice on the brush and spread over teeth; place brush in mouth before turning it on; vary brush position for each tooth surface; brush teeth and gingiva seperately; use light steady pressure
areas of special attention

brush position for occlusal brushing
place brush on occlusal surfaces of molar teeth with filament tips pointed into the occlusal pits at a right angle; position the handle parallel with the occlusal surface; extend toe of the brush to cover distal grooves of most posterior tooth
strokes for occlusal brushing
two acceptable strokes are suggested; vibrate brush in a slight circular movement while maintaining the filament tips on the occlusal surface; force filaments against occlusal surface with sharp, quick strokes; lift brush to dislodge debris, repeat about 10 times, moving from molar to premolar area, overlapping previous bush position

brush storage
brushes need to be kept in open air with head in upright position, apart from contact with other brushes; portable brrush container needs specific holes to give air temporarily until the brush is completely dry
