Comparing the outcome of necrotic cases using two different treatment methods.

Area of Science:

• Endodontic treatment outcomes
• Regenerative endodontics

Background:

• Necrotic teeth with periapical bone loss present a challenge in endodontic treatment.
• The efficacy of single versus multiple appointment endodontic procedures using intercanal medicaments requires further investigation.

Purpose of the Study:

• To compare the success rates of endodontic treatment in necrotic teeth using a two-appointment approach with calcium hydroxide versus a single-appointment approach without intercanal medicaments.

Main Methods:

• Forty-three necrotic single-rooted teeth with periapical bone loss were instrumented and irrigated.
• Twenty-three teeth received calcium hydroxide as an intercanal medicament for 10-21 days before obturation (two appointments).
• Twenty teeth were treated in a single appointment without intercanal medicaments.
• Treatment success was evaluated one year post-operatively based on radiographic evidence of lesion reduction or absence and absence of symptoms.

Main Results:

• All 23 teeth treated with calcium hydroxide (two appointments) demonstrated successful outcomes.
• Twelve of the 20 teeth treated in a single appointment were successful.
• A statistically significant difference in success rates was observed between the two groups.

Conclusions:

• Utilizing calcium hydroxide as an intercanal medicament in a two-appointment endodontic treatment protocol for necrotic teeth leads to a more reliably successful outcome.
• The findings suggest that multi-visit endodontic therapy incorporating calcium hydroxide enhances treatment predictability in compromised cases.
