Endodontics is the branch of clinical dentistry concerned with the prevention, diagnosis and treatment of diseases of the dental pulp and their sequela. In reality this implies root canal treatment. This volume lays the foundations for rationally-based endodontic treatment.

endodontic procedure for pain relief should be 83 properly appraised within a broader plan of care before definitive root canal treatment. • Due consideration should be given to the fundamentals of infection control in planning and preparing for treatment. • Sealing rubber dam isolation is mandatory for endodontic care. This does not need to be complicated or time consuming. Further Reading Dajani AS, Taubert KA, Wilson W, Bolger AF, Bayer A, Ferrieri P, Gewitz MH, Shulman ST, Nouri S,

exciting options for canal preparation and obturation, coronal access can be overlooked as a dreary – if sometimes stressful – precursor to be dispensed with quickly before the main event. In fact, coronal access holds the key to success and rewards those who check and refine their preparation before racing to the next stage. 86 A lower molar, well treated in the distal canal, but with a short and inadequate root filling mesially is shown in Fig 4-2. In haste to get on, the chamber was not

always concentric. When searching and probing for the pulp in a root, it can only be in the centre of the mass of dentine which it formed (Fig 5-2b,d). What About Apical Calcification? Failure to reach length in a canal is often blamed on apical calcification. In truth, canals do not suddenly calcify in their apical reaches, and are more commonly wider in this protected apical region than further coronally where external irritants can provoke dentine deposition. Deep obstructions usually

(Fig 6-1b). Fig 6-1b Longitudinally, preparations should be centred on the original canal and form smooth, regular tapers, from apical to coronal. Irrigants support enlargement by lubricating the path of instruments and flushing cutting debris, which may otherwise cause blockages and compromise cleaning. 130 Critically, they also clean the complex webs, fins, anastomoses and accessory canals which instruments will never be guided to enter (Fig 6-2). As such, they should have antimicrobial, and

buccal nerve and infiltrating beneath the periosteum of the thin lingual plate over the tooth apices may be helpful. Intraosseous injections in the form of: • periodontal ligament infiltration • intraseptal infiltration • delivery though a puncture hole in the buccal cortical plate 50 may also be potent supplements. Sometimes it is necessary to infiltrate directly into pulp tissue, which operates by high-pressure concussion of pulpal nerves and is independent of the anaesthetic agent. This
