Pathways of the pulp

[...]... death of the pulp, may result from an untreated irreversible pulpitis or may occur immediately after a traumatic injury that disrupts the blood supply to the pulp Whether the necrotic remnants of the pulp arc liquefied or coagulated, the pulp is still quite dead Regardless of the type of necrosis, the endodontic treatment is the same Within hours an inflamed pulp may degenerate to a necrotic state Pulp. .. The terms used in a clinical classification suggest the signs and symptoms of the disease process The primary purpose of a clinical classification is to provide terms and phrases that can be used as a means of communication within the dental profession In the final analysis, the pulp is either healthy or not and must either be removed or not The extent of the disease process may affect the method of. .. patient must be told about the reason for the test and how the test will be performed One or two teeth on the opposite side of the mouth (preferably the contralateral teeth) should be tested first so that the patient becomes acquainted with the sensation Testing the opposite side of the mouth also lets the clinician know the patient's normal level of response The electrode of the pulp tester should be generously... necessarily pathologic; they can be mere manifestations of degenerative aging in the pulpal tissue However, their presence may cause other insults to the pulp and may increase the difficulty of negotiating the root canals The incidence of calcifications in the chamber or in the canal may increase with periodontal disease, extensive restorations, or aging As the percentage of the population categorized... mobility In more severe cases the patient is febrile The extent and distribution of the swelling arc determined by the location of the apex, the location of the adjacent muscle attachments, and the thickness of the cortical plate The acute apical abscess is readily distinguishable from the lateral periodontal abscess and from the phoenix abscess 1 With the lateral periodontal abscess there may be swelling... may appear on the film When posterior teeth are being investigated, a bite-wing film provides an excellent supplement for finding the extent of carious destruction, the depths of restorations, the presence of pulp caps or pulpotomies, and dens invaginatus or evaginatus Generally it is true that the deeper the caries and the more extensive the restoration the greater is the probability of pulpal involvement... Generally, the thicker the enamel is, the more delayed the response Accordingly, thin anterior teeth yield a quicker response and broad posterior teeth a slower response because of the greater thickness of enamel and dentin An additional function of the electric pulp tester is testing vital teeth that have been anesthetized for pulp extirpation If the vital pulp has been profoundly anesthetized, the electric... infiltration of the maxillary teeth, starting with the most distal, should be used After each subperiosteal infiltration (0.25 ml) the clinician should wait 3 minutes The pain will cease completely with the onset of anesthesia around the source of the pain The most effective technique is intraligamentary injection administered in the distal sulcus of each suspect tooth When the offending tooth is anesthetized... quickly after the stimulus is removed is characteristic of reversible pulpitis Finally, a painful response that lingers after the thermal stimulus is removed indicates a symptomatic irreversible pulpitis Electric Pulp Tests The electric pulp tester is designed to stimulate a response by electric excitation of the neural elements within the pulp The patient's response to the electric pulp test does... repaired Diagnosis is confirmed by the general absence of symptoms, the presence of a radiolucency, and the absence of pulp vitality Radiographically the lesions may appear large or small, and they may be either diffuse or well-circumscribed The additional presence of a sinus tract indicates the production of frank pus Symptoms are generally absent because the pus drains through the sinus tract as quickly
