| Summary: | Root canal treatment is a treatment to preserve the teeth in the oral cavity.
The failure of this treatment is often caused by the bacteria which attached to the
walls of the dentin, and also the presence of smear layer. The complexity of the
anatomy of the tooth requiring irrigation solution to improve the cleaning of the
root canal. An ideal irrigation solution requires an ability to penetrate into the
dentin walls. The aim of this study was to determine the effect of the contact
duration of Phaleria Macrocarpa as the irrigation solution towards extensive
penetration into the dentin wall.
This research used 18 mandibular second premolars which cut on the
coronal section and the apical third. Subjects were divided into groups of
irrigation solution extracts Phaleria macrocarpa and NaOCl each of 9 subjects.
Each group were divided into 3 sub-groups each of 3 subjects. Sub-group I were
irrigated for 3 minutes, sub-group II for 5 minutes, sub-group III for 7 minutes.
Each group of subject were divided into 3 groups. Group I were irrigated for 3
minutes, 5 minutes in group II and group III for 7 minutes. The subjects were
tested the ability of penetration with a broad viewing area of penetration into root
canal wall dentin. Each subject was cut into 3 segments of upper, middle, and
bottom with a thickness of 1 mm, and were captured with a camera macrodigital
then processed with AxioVision software and digital imaging. The data were
analyzed using Manova test and LSD test followed by the 95% confidence interval
(P<0.05).
Manova test result showed a significant effect of contact duration of the
Phaleria macrocarpa extracts irrigation solution NaOCl against extensive
penetration to the root canal dentin walls (p<0.05). LSD test result showed a
significant difference between the duration of contact 3 minutes, 5 minutes, and 7
minutes of irrigation solution Phaleria macrocarpa extract with a solution of
NaOCl (p<0.05). In conclusion, contact duration of Phaleria Macrocarpa
extracts irrigation solution affect the extensive of penetration to the tooth root
canal dentin walls.
