Comparative Study of Experimental Dental Adhesive With and Without Phosphoric Acid Pretreatment...

Dental Caries

The intent of this study is to evaluate the clinical performance of an experimental dental bonding agent for use with dental restorative composites with and without pretreatment of the tooth dentin and enamel using phosphoric acid etching.

Clinical Evaluation of Nanoionomer Filling in Primary Teeth

Dental Caries

This clinical trial was performed to evaluate the nano-filled resin modified glass ionomer (RMGI) -with a brand name of "Ketac Nano"- as a filling material for the treatment of caries in primary teeth. Children aged 5-8 years were selected and treated with either Ketac Nano or another conventional RMGI called Vitremer. Then, the treated children were evaluated at baseline, after one yeat and after two years. The hypothesis to be tested in the present study was: The clinical performance of nano-filled RMGI (Ketac Nano) in class I primary molars will differ from that of its preceding conventional RMGI (Vitremer).

Indirect Pulp Capping With Resin Modified Glass Ionomer

CariesDental1 more

In deep carious lesions, presenting risk of pulp exposition, a treatment option is the partial caries removal of carious tissue followed by provisional restoration, while this approach is called indirect pulp capping. The aim of this double-blinding controlled randomized clinical trial is to evaluate the success of indirect pulp capping using only resin-modified glass ionomer, while the additional layer of calcium hydroxide was used as control. The sample of 112 molars and/or premolars (n=56), presenting deep carious lesions, from patients with age between 15 and 30 years treated in dental clinic at Department of Dentistry of Federal University of Sergipe. The selected carious lesions must be reached 2/3 of dentin, observed in bite-wing radiography, without pulp involving and/or other factor that to compromise the evaluation. After detailed anamneses, the selected teeth will be radiographed e all carious tissue from surrounding walls will be removed. At the floor of cavity, the carious tissue will be partially removed using hand dentin excavators, remaining the caries-affected dentin and avoiding the pulp exposition. The removed carious tissue from the floor of cavity will be evaluated for presence of Lactobacilos e Estreptococos Mutans, while the remaining dentin will be evaluated for consistency, colour and humidity. Randomly, the cavity will be provisionally restored with: Control - dress and cement of calcium hydroxide followed resin-modified glass ionomer; or Experimental - only resin-modified glass ionomer. The distance between the base of restoration and the pulp cavity cap will be measured by bitw-wing radiography. The patients will be re-evaluated after 15 days, while the teeth with compromised pulp vitality will be excluded from the study. The remaining patients will be evaluated after 6 months. The distance between the base of restoration and the pulp cavity cap will be measured again, followed by provisional restoration removal. The remaining caries-affected dentin from floor of cavity will be fully removed and a bacteriological evaluation performed. The consistency, colour and humidity of this tissue will be evaluated too. Finally, the permanent restorations will performed.

Is Biodentine, as Successful as, Mineral Trioxide Aggregate

Dental Caries

: A split-mouth controlled clinical trial was carried out on 21 healthy, three to seven years old children, with 42 pairs (84 molars) of contralateral mandibular primary molars indicated for pulpotomy. One paired tooth in one side was designated to Biodentine (Group 1) and the other side for MTA (Group 2) as a pulp medicament. All pulpotomized teeth were finally restored with stainless steel crowns. Subjects were monitored clinically and radiographically at one, three, six and 12 months.

Comparison of Biodentine and MTA Pulpotomies in the Primary Molar Teeth 3 Year Follow up

PulpotomyDental Caries

The aim of this study is to compare two pulpotomy medicaments in primary molars clinically.A total of 200 primary molars with deep caries were treated with two different pulpotomy medicaments (Mineral Trioxide Aggregate and BiodentineTM) in this study. The inclusion criteria for tooth selection were no clinical and radiographic evidence of pulp pathology. During 36 months of follow-up at 3-month intervals, clinical and radiographic success and failures were recorded.

Survival of Endocrowns Made From Different Ceramics

Pulp DiseaseDental2 more

Restoration of endodontically treated teeth requires a means to protect the cusps from the wedging forces of occlusion. When there is extensive loss of tooth structure, cuspal coverage is warranted. Usually this is in the form of indirect restoration. Traditionally, full coverage crowns have been used which would require further removal of sound tooth structure. Recently, adhesive alternatives have been introduced which allow for conservation of tooth structure. Different materials can be used for this purpose. The evidence on the long-term survival of these materials is scarce. This study aims to investigate the short and medium-long term survival rate of these prostheses.

Evaluation of CAMBRA Versus ICCMS Caries Risk Assessment Models Acquisition On Treatment Plan

Dental Caries

randomized clinical study to evaluate 'caries management by risk assessment' Versus 'international caries classification and management system' Caries Risk Assessment Models Acquisition On Treatment Plan In Young Adult Population with null hypothesis that International Caries Classification and Management System (ICCMS™) will have the same clinical performance as Caries management by risk assessment (CAMBRA)
