简要总结
This trial is test the dentin hypersenstivity using Giomer based Varnish versus Bioactive glass air polishing system in patients with non-cervical lesions.
详细描述
To investigate the clinical effectiveness of Giomer based varnish versus Bioactive glass air polishing System in the management of dentin hypersensitivity and tooth color change in the cervical lesions.
P:Patient/Population: Middle aged patients complaining of cervical dentin hypersensitivity. I: Giomer varnish containing surface pre-reacted glass fillers. C: Bio-active glass air polishing system: O:Dentin Hypersenstivity (Primary Outcome) was assessed by three different stimuli (evaporative , thermal and tactile) . O: Color Change (Secondary Outcome). T: Baseline, T1, T2, T3. S:a randomized clinical trial.

研究组 & 干预措施
Giomer varnish containing surface pre-reacted glass fillers
Giomer-based varnish is a light-curable varnish/desensitizer. The surface pre-reacted glass (S-PRG) filler is a bioactive trilaminar structure with a multifunctional glass core embedded in resin matrix. It can release and recharge fluoride ions. When it becomes in contact with the oral fluids, it starts to bind to the collagen fiber and release six different types of ions like fluoride, calcium, phosphate that help in the formation of apatite crystals and seal the open dentinal tubules with a long-lasting effect Brand name: S_PRG (Shofu-Japan)
干预措施: Giomer varnish containing surface pre-reacted glass fillers (Other)
Bioactive Glass Air Polishing
Bioactive glass powder delivered by an air-polishing device (ProJet 1) equipped with a 0.6-mm-diameter nozzle and a particle size range: 38-90 µm . A bioactive material that reacts with saliva to deposit Hydroxycarbonate Apatite crystals (HCA), which is very strong and resilient. The continuous release of calcium ions promotes constant protection and long lasting seal of the tubules. Using the air polishing delivery system helps to provide a huge amount of calcium and phosphate particles at the exposed surface of the tooth. Moreover, the air pressure aids in pushing these particles inside the dentinal tubules to a considerable depth. Air polishing using such powder provides a bifunctional advantage of occluding the dentinal tubules. However, there is limited clinical trials testing the efficacy of the bioactive glass powder air polishing system in minimizing the dentin hypersensitivity

结局指标
主要结局
Pain due to dentin hypersenstivity
时间窗: baseline preoperative, immediate postoperative, 1 , 6 and 12-months' time
Dentin hypersensitivity was assessed by three different stimuli (evaporative , thermal and tactile) to simulate the different situations in which Dentin hypersensitivity arises. Using the Visual Analog scale (VAS), the participant marks the pain intensity on a graduated 10 cm straight line (0 = no pain, 10 = extreme pain)
次要结局
- Color change (Tooth discoloration)(Baseline preoperative, immediate postoperative, 1,6 and 12-months time)
