pulpotomy (34.5%) had low success rates after -1 %-year follow-up, and the vast
majority of the treatments failed due to pain.
The final part of the dissertation focuses on possible factors shaping endodontic
treatment quality among GDPs. A factor that could explain a sub-optimal treatment
quality was a low rate of adoption of new technology (such as nickel-titanium
instruments, apex locators and warm gutta-percha techniques). Also the rare use of
rubber dam was noted (Study IV). Other factors influencing treatment outcome
investigated amongst the GDPs were their endodontic knowledge, arid their skills and
attitude to various endodontic topics based on 'self-assessments'. The creation of an
aseptic operation field was regarded as the most difficult procedure, whereas root
canal treatment was evaluated as relatively easy and was carried out rapidly (Study
II). With respect to treatment outcome the GDPs seemed to put too much emphasis
on factors associated with clinical symptoms, and too little emphasis on factors
related to infection condition such as 'periapical status' and 'root canal infection'
(Study V). Concomitantly, the GDPs regarded the technical root filling quality as
important for the outcome of the treatment (Study V). The vast majority of the GDPs
rarely assessed themselves as being at a non-satisfactory level with respect to 'root
canal preparation procedure' and 'root filling procedure'. The only topic where the
GDPs assessed themselves as being at a non-satisfactory level was 'microbiology'.

In the interplay between the dentist and the patient, the second most frequent
malpractice claim category was endodontic treatment (Study VI). The most frequent
reason for sub-optimal endodontic treatments was technical shortcomings and
technical treatment complications. Male dentists and female patients were overrepresented
in the material indicating a sex influence on aspects of the patient-dentist
communication that are important for liability claims. No specific attention was paid to
the importance of an aseptic technique during root canal treatment in the available
reports from the complaint boards. Thus, the focus on endodontic infection control
seems not yet entirely integrated between the education platforms found within the
universities in Denmark.
