Time to fracture (Ttf) and Length of fractured fragments (mm) of reciproc blue R25 used in one first mandibular molar with truss access cavity (TAC) or conservative access cavity (CAC).

Table 1: Time to fracture (Ttf) and Length of fractured fragments (mm) of reciproc blue R25 used in one first mandibular molar with truss access cavity (TAC) or conservative access cavity (CAC).

Endodontic access cavity	Cyclic fatigue (TtF) (seconds)		Fractured fragment length (mm)
Endodontic access cavity	Mean	SD	Mean	SD
CAC	742.5^a	188.949	5.18^a	0.16
TAC	631.6^b	199.737	5.12^a	0.18

The same letters in a column show differences not statistically significant (P > 0.05).

SD: Standard deviation.
