Abstract

Purpose

To evaluate imbibition and syneresis in four commercially available irreversible hydrocolloid (alginate) impression materials at different time intervals (10, 20 and 30 minutes).

Materials and methods

Eighty samples of four commercially available irreversible hydrocolloid (alginate) impression materials Algitex (DPI, Mumbai), Plastalgin (Septodont, Cedex, France), Zelgan 2002 (Dentsply), Finndent (Pyrex Polykem) were made. Twenty samples each of four irreversible hydrocolloid (alginate) impression materials were grouped into four groups (I, II, III and IV). Measured quantity of alginate powder and liquid was used to make samples. The samples were evaluated for imbibition and syneresis at different time intervals (i.e.10, 20, and 30 minutes) by weighing on electronic analytic balance. The data were analyzed using the one-way ANOVA, post hoc test and t-test.

Results

The statistical data revealed that imbibition within four groups of irreversible hydrocolloid (alginate) impression materials were not significant. Regarding syneresis there was insignificant difference between the four groups but within the group itself they showed significant difference between them depending upon the time interval. It was observed that Group I showed significant difference in syneresis at time interval of 10 to 20 minutes. Group II showed significant difference in syneresis at time interval of 10 to 30 minutes.

Conclusion

This study demonstrated that four groups of irreversible hydrocolloid (alginate) impression materials showed different rates of imbibition and syneresis at time interval of 10, 20 and 30 minutes depending upon molecular weight, calcium concentration and environmental conditions.

Effectiveness of Premedication with Analgesics vs Placebo for Success of Inferior Alveolar Nerve Block in Irreversible Pulpitis

Abstract

Aim

To conduct a randomized-placebo controlled clinical trial to compare the effectiveness of premedication with analgesics vs placebo for success of inferior alveolar nerve block in irreversible pulpitis.

Materials and methods

The study consisted of 80 adult patients attending operative Outpatient Department in Baqai Dental College. Informed Consent was obtained from each participant. Subjects were randomly divided in four groups comprising of 20 subjects in each group. Group A received piroxicam (Feldene 20 mg, Pfizer), group B received diclofenac potassium (Fastaid Plus, 50 mg platinum pharmaceutic), group C received naproxen sodium (Synflex 550 mg, ICI), and group D received a placebo drug becefol (Abbott). Medication was given 1 hour before initiating endodontic treatment. After 1 hour of oral administration of tablets, inferior alveolar nerve block using 1.8 ml of 2% lidocaine containing 1: 200,000 epinephrine was given. After 15 minutes, access cavity preparation was initiated and patients were asked to inform if they experienced pain. Patients were excluded from the study if they experienced pain but if the patient did not feel pain endodontic treatment was continued. p-value was set at 0.05. Data was analyzed by using Chi-square test (SPSS 19).

Results

The result showed that out of 80 patients who participated in the study, success rate for piroxicam came out to 90% (10 male and 8 female patients), followed by diclofenac potassium with 75% success rate (9 male and 6 female patients), naproxen sodium with 35% success rate (3 male and 4 female patients) and placebo with 10% success (1 male and 1 female patient).

Conclusion

The current study concludes that premedication given 1 hour before injecting anesthesia is helpful in reducing pain intensity and thus causing inferior alveolar nerve block to be effective.

Evaluation of Microleakage in Class V Composite Restoration using Different Techniques of Polymerization

[Year:2012] [Month:January-March] [Volume:2] [Number:1] [Pages:6] [Pages No:10 - 15]

Abstract

Aims

The purpose of this study was to evaluate the effect of light intensity and curing cycle of quartz tungsten halogen (QTH) and plasma arc curing (PAC) lights on the microleakage of class V composite restorations.

Materials and methods

A total of 60 freshly extracted human maxillary premolars were used for this study. Standardized class V cavities were prepared and restored with microhybrid resin composite. According to the curing protocol, the teeth were then divided into three groups (n = 20): QTH curing (standard and soft start mode) and PAC high intensity irradiation.

  The microleakage was evaluated by immersion of the samples in 50% silver nitrate solution. The samples were then sectioned, evaluated under a stereomicroscope and scored for microleakage.

Statistical analysis used

Dye leakage scores were obtained, and analysis was done using Student's t-test.

Results

Light curing with QTH light in the soft start mode, showed the least leakage in the composite restoration, which was highly significant when compared with the other groups (p < 0.01). Light curing with QTH light in the standard mode, showed moderate microleakage, which was statistically significant (p < 0.05), when compared with the PAC high intensity curing. Curing with PAC light in high intensity mode resulted in severe microleakage along the cavity margins.

Conclusion

Within the limitations of the study, it may be concluded that:

1. The high intensity PAC light resulted in maximum leakage, when compared to the other groups in the study.

2. The soft start polymerization mode offers a distinctive advantage over the standard curing protocol, in terms of microleakage, for the QTH curing lights.

Clinical significance

In the clinical scenario, soft start curing regimen offers a distinctive advantage over the conventional mode of the QTH curing and the high intensity rapid curing offered by the PAC light.
