Comparative efficacy of photo-activated disinfection and calcium hydroxide for disinfection of remaining carious dentin in deep cavities: a clinical study.

Sharma S, Logani A, Shah N - Restor Dent Endod (2014)

Bottom Line: Successful outcome with an increase in radiographic grey values were observed in all three groups.However, on inter-group comparison, this change was not significant (p > 0.05).They can be used independently in IPT, since combining both does not offer any additional therapeutic benefits.

ABSTRACT

Objectives: To comparatively evaluate the efficacy of photo-activated disinfection (PAD), calcium hydroxide (CH) and their combination on the treatment outcome of indirect pulp treatment (IPT).

Materials and methods: Institutional ethical clearance and informed consent of the patients were taken. The study was also registered with clinical registry of India. Sixty permanent molars exhibiting deep occlusal carious lesion in patients with the age range of 18 - 22 yr were included. Clinical and radiographic evaluation and set inclusion and exclusion criteria's were followed. Gross caries excavation was accomplished. In group I (n = 20) PAD was applied for sixty seconds. In group II (n = 20), CH was applied to the remaining carious dentin, while in group III (n = 20), PAD application was followed by CH placement. The teeth were permanently restored. They were clinically and radiographically followed-up at 45 day, 6 mon and 12 mon. Relative density of the remaining affected dentin was measured by 'Radiovisiography (RVG) densitometric' analysis.

Results: Successful outcome with an increase in radiographic grey values were observed in all three groups. However, on inter-group comparison, this change was not significant (p > 0.05).

Conclusions: PAD and CH both have equal disinfection efficacy in the treatment of deep carious dentin. PAD alone is as effective for treatment of deep carious lesion as calcium hydroxide and hence can be used as an alternative to CH. They can be used independently in IPT, since combining both does not offer any additional therapeutic benefits.

Figure 2: Densitometric analysis of remaining affected dentin after IPT.IPT, indirect pulp treatment.

Mentions: Radiographic evaluation also included measuring of relative density of the remaining dentin using a software available on RVG machine. The 'Intraoral' option in the main menu bar of the Kodak RVG Trophy Imaging Software 6.12.10.0 was used. The 'Tools window' was navigated and 'Densitometric analysis' was clicked. Two defined and repeatable points (i.e. A and B) were identified in the immediate post-treatment and subsequent follow-up bitewing radiographs (Figure 2). 'A' denoted a mark 0.5 mm below the deepest part of the restored cavity and 'B' referred to a mark exactly perpendicular to A on the roof of the pulp chamber. The average grey value along the line joining the two points was noted and correlated with the data obtained on subsequent follow-up. Statistical tests were performed using the Stata 11.0 software (Stata Corp, College Station, TX, USA). The p value was set at 0.05.
