Treatment OutcomesTreatment Outcomes

Retrospective studies have shown that the success rate of teeth without apical periodontitis remaining free of disease after initial treatment or those with orthograde retreatment is 92 to 98 percent. The chance of teeth with apical periodontitis to completely heal after initial treatment or retreatment is 74 to 86 percent, and their functionality over time determined to be 91 to 97 percent.

The difference in outcome between initial treatment and orthograde retreatment

does not appear to be significant.

Susceptibility of a Polycaprolactone-Based Root CanalFilling Material to Degradation. II. Gravimetric Evaluationof Enzymatic Hydrolysis…..Tay et al

Polycaprolactone is susceptible to enzymatic biodegradation via ester bond cleavage. This study examined the susceptibility of Resilon, a polycaprolactone-based root filling material to enzymatic hydrolysis. Resilon, gutta-percha, and polycaprolactone disks, prepared bycompression molding, were incubated in phosphatebuffered saline, lipase PS or cholesterol esterase at 37°C for 96 h. They were retrieved at different time intervals for gravimetric analysis and scanning electron microscopy. The materials exhibited slight weight gains when incubated in phosphate-buffered saline that can be attributed to water sorption. Gutta-percha showed similar weight gains in

the two enzymes. Conversely, Resilon and polycaprolactone exhibited extensive surface thinning and weight losses after incubation inlipase PS and cholesterol esterase. Glass filler particles in Resilonwere exposed following surface dissolution of the polymer matrix, creating rough surface topography. Biodegradation of Resilon by bacterial and salivary enzymes warrants further investigation oftheir activities using cultures of endodontically relevant microbes and human saliva extracts.
