The Rootcanal treatment is considered as the most accurate one
followed in (( dentistry )), which need a right diagnosis and exact
treatment steps to be performed completely for an excellent
prognosis treatments ended by along time –perfect success.
One aim of the root canal treatment is providing compact
three dimensional seal for the canal system to prevent germs
enter and its products across both the apical and coronal
ways.
Gutta-Percha is the most use material to fill the radicalism
ca
nals. It has limited importance in spite of many
specifications as lack of the link to the ridge canal.
Aim of the study was To Compare the efficiency of R
ProTaper and R-Endo retreatment files in the removal of
conventional gutta-percha and resin coated gutta-percha and
time required. 60 extracted single root premolars were selected,
and then divi
ded into two groups according to the obturation
material. Next, each group was divided into two groups
according to the methods of retreatment.
Pulpectomy was performed on 100 primary teeth and the radiograph
was exposed immediately post treatment to observe weather the root
canal filling was: flush-undefiled or overfilled.
Teeth were examined periodically, clinically and radio graphically to
assess success of the treatment.
To evaluate the technical quality of root canal treatment performed by
undergraduate students and to detect iatrogenic errors.
This study aimed to asses of role of obturation material (zinc oxide and eugenol
cement with gutta-percha points, Resilon) on the efficiency of endodontic retreatment with Pro-taper
system of the following respects: the degree of cleanliness of the
canal, complications, working time.
