Abstract

The ultimate mission of root canal obturation is to avoid penetration of oral fluids containing bacteria, to periapical tissues. The purpose of research is far from clinical observations reveal whether there are periapical changes in dependence on the type of coronal restoration of the teeth that were either not covered by artificial crowns. 96 intra-oral X-rays and 50 panoramic X-ray images and records of medical cards of patients (Form .043) primary dental patients (30 women and 20 men) who applied for the purpose of prosthetic treatment, carried out an analysis of 344 teeth, 291of which were endodontycally treated and have medical indications for crowns covering and 53teeth were covered with crowns with preserved pulp. Teeth were divided into eight groups by type of restoration and divided by gender. Term follow-up after endodontic treatment ranged from 4 to 7 years. The calculation of ratios is in the analyzed groups. Shares in the groups were compared using Student's t-test. The result of the study found that from 112 endodontic treated teeth not covered with crowns only 14 teeth are applied pinning system while the teeth covered with crowns from 232 in 107 pins were used for reinforcing construction. Preference for rebuilding tooth with flexible pin provided only 2.68% and 3.88% of cases, that respectively indicates the lack of prevalence of modern methods as the method of choice.

Endodontic treated teeth that were covered by crowns, have better long-term outcomes compared with dental crowns that are not covered. Pin designs reduce the likelihood of seal failure under occlusal forces root system and thus improve prognosis results. Cast metal core has statistically efficient results compared to standard metal pins. The teeth with intact crowns covered with pulp had the lowest periapical pathology among all groups, indicating the need of use this method if conditions permit clinical situation. The study confirmed the need for a high crown and root absence of microleakage to achieve a high level of success for clinical results. Obtained clinical data give perspectives for further research of coronal reconstruction options to achieve a higher level of clinical success. As a result of comprehensive clinical and radiological examination the role of necessity of quality sealed teeth restauration was established which have indications for covering with the crown, to reach statistically higher level of periapical pathology absence.
