Abstract

Background: Importance of fluoride in dental restorative materials for preventing secondary caries. Several commercially available tooth-colored dental restorative materials, such as glass ionomer cement, resin composites, and compomers were used for this study.

Aim: To evaluate the amount of fluoride release from tooth-colored restorative materials [Conventional Glass Ionomer Cement (GC Fuji II)], Resin-modified Glass Ionomer Cement (ACTIVA BioACTIVE-RESTORATIVE), and Giomer (BEAUTIFIL II LS)] using ion-selective electrode (ISE) and spectrophotometer using zirconyl alizarin red dye method.

Materials and methods: A total of 90 extracted premolars were divided into two control groups and four experimental groups. Group I: GC Fuji II/ISE; Group II: BEAUTIFIL II LS/ISE; Group III: ACTIVA BioACTIVE-RESTORATIVE/ISE; Group IV: GC Fuji II/Spectrophotometer; Group V: BEAUTIFIL II LS/Spectrophotometer; and Group VI: ACTIVA BioACTIVE-RESTORATIVE/Spectrophotometer. The amount of fluoride released was analyzed using an ion-selective elective method and spectrophotometer. The results were analyzed using a one-way analysis of variance and Scheffe post hoc tests (P ≤ 0.05).

Results: Groups I and IV exhibited the highest fluoride release (1.42 and 1.12 ppm), which was statistically significant (P < 0.05) compared with Groups II and V, which showed the least using both methods. The fluoride release pattern of ACTIVA BioACTIVE (Groups III and VI) restorative was significantly lower than that of glass ionomers and showed no significant difference from the giomers groups (Groups II and IV).

Conclusion: Conventional glass ionomer cement (GIC) showed the highest fluoride release followed by enhanced resin-modified GIC and giomer irrespective of the methods used. Fluoride ion concentration values obtained from the ISE method, and spectrophotometer method were comparable. Alizarin red dye can be used as an alternative to sulfanilic acid azochromotrop dye for the estimation of the release of fluoride ions from dental materials, which is known to be sensitive and much more economical compared with the latter.

期刊介绍： It is a journal aimed for research, scientific facts and details covering all specialties of dentistry with a good determination for exploring and sharing the knowledge in the medical and dental fraternity. The scope is therefore huge covering almost all streams of dentistry - starting from original studies, systematic reviews, narrative reviews, very unique case reports. Journal scope is not limited to these subjects and is more wider covering all specialities of dentistry follows: -Preventive and Community dentistry (Dental public health)- Endodontics- Oral and maxillofacial pathology- Oral and maxillofacial radiology- Oral and maxillofacial surgery (also called oral surgery)- Orthodontics and dentofacial orthopedics- Periodontology (also called periodontics)- Pediatric dentistry (also called pedodontics)- Prosthodontics (also called prosthetic dentistry)- Oral medicine- Special needs dentistry (also called special care dentistry)- Oral Biology- Forensic odontology- Geriatric dentistry or Geriodontics- Preventive and Social Medicine (Public health)- Our journal appreciates research articles pertaining with advancement of dentistry, preventive and community dentistry including oral epidemiology, oral health services research, oral health education and promotion, behavioral sciences related to dentistry, dental jurisprudence, ethics and oral health, economics, and quality assessment, recent advances in preventive dentistry and community dentistry.
