Description

RCT Diagnosis CLINICAL PULP A. Normal pulp -Symptom free unless stimulated B. Diseased pulp 1. Reversible pulpitis 2. Irreversible pulpitis a. Symptomatic Irreversible pulpitis b. Asymptomatic Irreversible pulpitis Reversible pulpitis -asymptomatic in absence of stimuli -sharp pain of short duration -normal periapical diagnosis -increase response to cold that is non lingering -symptom relieved once stimulus is removed Irreversible pulpitis -lingering painful thermal response esp. COLD (also hot) -throbbing pain causing sleepless nights -pain when biting (periapical involvement) a. Symptomatic Irreversible pulpitis -paroxysm of pain -excited by: * sudden temp change * cold,acid or sweet *pressure from food impaction b. Asymptomatic Irreversible pulpitis -basically symptomless unless stimulated -mild to mod. Painful response that lingers after removal of stimuli NECROSIS -death of pulp -devitalized pulp -non responsive pulp -pulpless (endo. Treated)

PERIRADICULAR A. Normal periapical tissue (WNL) - asympyomatic to tapping and palpation - intact lamina dura - normal pdl space B. Apical Periodontitis 1. Symptomatic (acute) Apical periodon. -inflammation of apical Periodontium -MAY/MAY NOT be assoc with apical radiolucency -mild discomfort to painful response to biting/percussion 3. Asymptomatic (chronic) Apical periodontitis - long standing periapical inflammatory lesion -no clinical symptom -Rx eveident:apical radiolucency *granuloma *cyst *chronic alveolar abcess *condensing ostetitis *apical scar diagnostics: di ko nilagay lahat -palpation -thermal test HOT then COLD -electric pulp test -test cavity -percussion (not a vitality test) -mobility & depressibility test -anesth test -radiograph

Centric Relation (aka retruded contact position/ligament guided position/bone to bone contact/terminal hinge position) - a maxillomandibular relationship where in the condyle-disc complex is in the most superior and anterior position against the articular eminence, and the condle contacts the avascular portion of the articular disc. The position is clinically discernible and is irrespective of vertical dimension and tooth contact. In this position the mandible is restricted to purely rotational movements. *Note: old definition - condyle is in the most superior and retruded position Centric occlusion - occlusion of opposing teeth when the mandible is in the centic relation position. May or may not coincide with the maximum intercuspal position. Maximum intercuspal position complete intercuspation of opposing teeth independent of condyar position....
