The most common endodontic treatment of primary teeth is pulpotomy, which is used in the case of carious, iatrogenic or traumatic damage of the pulp. As prerequisite for such a procedure, the patient has to be free of clinical symptoms, according to the DGZMK.1 As per UK Guideline2 and Weisshaar,3 this condition is still met in cases of temporary discomfort or short, spontaneous pain...

I 29 research _ primary teeth endo I roots3_2010 The mortal amputations were attributed partly to Toxavit-devitalisationandpartlytotreatmentofgan- grenous teeth. Devitalised teeth were treated in the same manner as vital teeth. Gangrenous teeth were treatedwithdifferentmethods.Simplemortalampu- tations were performed in a manner similar to a vital amputation. Root-canal fillings (partial or complete) weresimplyfilledwithpaste.Insomecases,theroots were finished through artificial fistulation, which was done interradicularly—mostly with a Cavit lifter through the mucosa—and in a few cases after the mucosa had been shifted with a turbine bur. All endodontic measures, including the fillings, were performed in one appointment. Additional vis- its were only necessary when massive bleeding oc- curred, when a composite filling was required and in devitalisation cases. In the first two cases, the cavity was filled with excess N2 or with zinc oxide-eugenol following N2 application. N2 application and imme- diate amalgam sealing of the cavity without lining materials is still the most time-saving method. In exceptional cases, stainless-steel crowns served as definitive restoration. _Results A total of 559 primary teeth were treated endo- dontically between 1992 and 1998.

In 22 cases, root filling or mortal amputation was followed by artificial fistulation. Root-canal treatment of 11 gangrenous primary molars was performed without fistulation. The following gives the average age of the patients who underwent a pulpotomy: maxillary first molar: 7 years, 6 months maxillary second molar: 7 years, 5 months mandibular first molar: 6 years, 6 months mandibular second molar: 6 years, 6 months After treatment, 11.8% (n = 66) of the young patientsdidnotreturntothepractice,whichleftonly 88.2% of the original patient group (n = 493) for Figs. 5–9_13-year-old patient.
