Differences in the tooth whitening effect between strawberry juice and apple juice in-vitro

Bleaching is the tooth whitening by applying chemical materials oxidizing the organic tooth pigmentation and creating smaller and lighter molecules. Commonly used in the tooth bleaching is hydrogen peroxide. Strawberry and apple contain hydrogen peroxide and ellagic acid which will bond with an unsaturated bond of the tooth pigmentation. The purpose of this research was to finding out and measuring the tooth whitening level and effectivity between the strawberry and apple juice. The type of this research was a true experimental (in-vitro), using 30 samples of maxillary premolars with cutted radicular until the CEJ. Samples were divided into 3 groups (immersed in strawberry juice; apple juice; and mineral water); with three times daily immersion in one week. The tooth colour level was measured using a spectrophotometer. Data were analyzed using the one-way ANOVA and LSD test. The results showed significant differences among all groups. Normality test showed the variance between homogenous groups, with the p-value of 0.198 (p ≥ 0.05). The one-way ANOVA test results showed a significance value (0.000), indicated a significant degree of the tooth whitening level between all groups. The LSD test results showed that the tooth whitening level in group I (immersed in strawberry juice) was significantly different to group II (immersed in apple juice) and group III (immersed in mineral water), with a significance value of 0.01 and 0.00 ( p ≤ 0.05). The tooth whitening level in group II was significantly different from group III, with a significance value of 0.03 (p ≤ 0.05). There were differences in the tooth whitening level between immersion in strawberry juice, apple juice, and mineral water, with the most effective tooth whitening level found in the strawberry juice immersion

The effect of Beetle leaves (Piper Betle Linn) for dental caries formation

Dental caries is still the main problem in dental and oral health. Caries is caused by several factors working simultaneously. The main principle of management caries is by prioritizing preventive action and avoiding invasive action. Beetle leaves are medicamentous plant which are widely cultivated and very beneficial for Indonesian people. Its active content enable beetle leaves to be used as antimicrobial, antiseptic, antifungal, antioxidant, and disinfectant. The government of Indonesia and WHO greatly support the utilization of natural resources as medical cure. Currently we can find a lot of toothpaste and mouthwash products which use beetle leaves as additional ingredient. Various researches have proved that the use of beetle leaves extract as mouthwash, toothpaste and chewing beetle leaves may decrease plaque score. Chavicol and chavibetol content enable beetle leaves to function as very good antimicrobial. Beetle leaves also contain charvacrol, eugenol, methyl eugenol, cadinene, and seskuiterpene, which can function as antiseptic. Beetle leaves may effect salivary function and secretion and also impede the forming of dental caries

Comparison of the removal of calcium hydroxide medicaments on the root canal treatment irrigated with manual and sonic agitation technique

Introduction: Irrigation of the root canal is an important part of the endodontic treatment. Root irrigation technique can be done with the manual and sonic system by using 2.5% NaOCI solution. Calcium hydroxide [Ca(OH)2 ] is used as a medicament for root canal sterilization. Root canal treatment will fail due to the imperfect removal of Ca(OH)2 residue. The objective of this research was to analyze the comparison of the removal of Ca(OH)2 medicaments on the root canal treatment irrigated with manual and sonic agitation technique using 2.5% NaOCI. Methods: The methods used in this study was experimental laboratory. The sample used was 30 maxillary incisors. The teeth were then divided into two groups randomly, then the root canal preparation was done by the crown down technique with irrigation using 2.5% NaOCI. The radicular part of the teeth was then split longitudinally, given a standardized groove in the one-third of the apical part, then applied with water-solved calcium hydroxide. The teeth were unified afterwards by using flowable composites, then soaked in the artificial saliva. The sample of the 1st group was irrigated by manual agitation technique, and the 2nd group by sonic agitation technique. The data results were analyzed by Kruskal-Wallis and Mann-Whitney tests. Results: The results of Ca(OH)2 removal were different between manual agitation technique compared to the sonic agitation technique. Conclusion: The irrigation using 2.5% NaOCl with the sonic agitation technique were proven to be more effective in removing Ca(OH)2 from root canals than the manual agitation technique

<strong>Differences of Micro-CT evaluation of the obturation sealing capability between thermoplastic carrier-based condensing techniques and lateral heat condensation techniques</strong>

ABSTRACT  Introduction: Root canal filling is an important part of root canal treatment that aimed to seal the root canal system, to prevent bacterial penetration and their toxins into periradicular tissues and to provide favourable environment for periapical healing. Thermoplasticized technique were developed to produce filling with homogenous mass, to achieve optimal sealing ability and to increase the quality of root canal filling. The aim of this study is to analyzed differences of Micro-Computed Tomography (Micro-CT) evaluation of the obturation sealing capability between thermoplastic carrier-based condensing techniques and lateral heat condensation techniques. Methods: This study was conducted under an in-vitro quasi experimental methode to 36 specimens of maxillaris centralis incisivus which were divided to 3 groups, (A) thermoplasticized carrier-based technique (GuttaCore System), (B) warm lateral condensation technique (heat carrier SystemB), (C) cold lateral condensation as control group. Sealing ability is evaluated based on the measurement results of volume percentages of filling material and sealer, volume of void, and surface density, that which was calculated from the 3D volumetric image of Micro-CT device. Data were statistically analysed using Analisis of Variance (ANOVA) and t-test. Result: The result showed significant difference of percentage filling material and sealer volume in apical third (p0.05). Conclusion: Thermoplastized carrier-based technique is not better than warm lateral technique.
