Abstract
This longitudinal study done in Dr.sameer Hatem private clinic by the aid of Dr.Abbas Hayder, that was collected
for 93 patients who are treated in the clinic and periodic inspection and imaged radiographically during this period of
time to obtain the total healing for periapical lesion (radiolucency), all these patients show no sign and symptoms of
pain or swelling after root canal therapy, the patients are examined by using (woodpecker intra oral x-ray sensor and
CSN x-ray machine)
This samples was selected between the age of 13 and 82 years old, 48 female and 45 male. Time required for the
samples to be healed between 7 months – 1 year and 4 months for the whole samples.
General health for these patients included healthy, and some of them are medically compromised patients with some
systemic disease (Hypertension, Diabetes, Angina pectoris, Atherosclerosis, Epilepsy, Hypotension and Asthma)
In this sample there was 15 diabetic patients and one of them was 18 years old and the course time required for this
patient was 7 months.
This sample include 15 smoker patients, some of them are heavy smoker who smoke more than 20 cigarettes per
day.
Conclusion: In this study concluded that the process of repairing endodontically treated teeth depends not only on
the correct clinical approaches to promote a better RCT (such as use of good irrigant solution, intracanal dressing,
and root canal filling), and in this study we highlighted the impact of the systemic factors (such as chronic diseases,
hormones, and age) that can change the host's immune defenses and interfere in the outcome of root canal treatment
and in the healing process and the healing time of nonsurgical root canal treatment..
