Abstract

Endodontic instrumentation is a critical step in root canal therapy that involves cleaning
and shaping the canal system. While it effectively removes infected tissue and shapes the canal for obturation, it also impacts the fracture strength of the treated tooth. So, endodontically treated teeth are considered to have a lower survival rate compared to vital teeth. Objective: This study aimed to evaluate the rate of influence of the factor endodontic treated and root-filling to the fracture strength of the tooth compared to the intact tooth. Materials and methods: After applying criteria for selection, fifty extracted
single-root noncarious teeth were randomly divided into 2 groups and 4 subgroups: 1а)
intact teeth, 1b) decoronated teeth, 2a) instrumented with Hedstrom file and obturated, 2b) instrumented with Hedstrom file and insert fiber post. After instrumentation, irrigation and obturation, all specimens were placed into EXMAL 1 models. Then, the fracture strength was tested with the Universal testing machine. Results: The intact teeth had the highest mean value of the fracture pressure among the specimen groups, i.e. 1346.9± 320.25 (min 954, max 2030), while the endodontic instrumentation decreased the tooth strength. At the same time, they had (instrumented and obturated group of
specimens) the lowest rate of pressure 867.23± 108.76 (min 647, max 1051). Fiber post subgroup had 802.13± 95.04 (min 647, max 963) force of fracture pressure in comparison to instrumented and obturated subgroup 932.33± 79.93 (min 806, max 1051), which had a higher rate of fracture resistance. Conclusion: The major risk factor that influence on the fracture resistance of the tooth is the endodontic instrumentation. Intact teeth have the highest rate of strength. Gutta-percha/Endometasone N single cone technique showed higher strength than obturated teeth and reinforced with fiberglass post.
