Aesthetic and Functional Evaluation of a Universal One-Shade Composite in Primary Maxillary Incisors

2026年7月15日 更新者:Ruhi Sanvordekar、Goa Dental College

Evaluation of the Aesthetic and Functional Properties of A Universal One-Shade Composite Material With Chameleon-like Properties: A Longitudinal Split-Mouth Randomised Controlled Trial

  • Use of tooth-coloured fillings is an essential part of Pediatric dentistry as most patients desire fillings which look like natural teeth.
  • Lately, there is a vast variety of shade-choices in filling materials which complicates colour matching procedure, increases cost and increases treatment time.
  • Universal One shade composite filling materials have been developed to overcome these disadvantages. Omnichroma (Tokuyama Dental, USA) is one such material, introduced in 2019.
  • Manufacturer claims that it can match colour of surrounding tooth, irrespective of its shade, which may be an advantage for patients as well as pediatric dentists.
  • In child patients where chairside time, child's cooperation are important, this new one shade filling material Omnichroma, may prove to be better than multi shade composite filling materials, regarding color matching, color stability and other functional properties.
  • There are very few studies on this new material, that have assessed its actual performance in patients, and more studies would be useful to generate scientific evidence for dentists to use.
  • In this study we will fill one of your child's decayed front tooth with the new One shade filling material Omnichroma, and the other decayed front tooth with the usual conventional multi shade filling material 3M Filtek Z350 after colour matching followed by evaluation and taking of intraoral photographs.
  • You would be required to report for follow ups at 3, 6 and 12 months interval for a repeat evaluation and intraoral pictures.

次要结果测量

结果测量
措施说明
大体时间
Photographic/Digital Colour match
大体时间:Baseline, 3 months, 6 months, 12 months
A software was used to provide CIE L*, a*, and b* values for one point over the tooth surface (Pt B) and one point over the restoration (Pt A). The colour match/difference (ΔE) between the restoration (Pt A) and the adjacent tooth structure (Pt B) was calculated using the CIEDE2000 colour difference formula through the software algorithm. Lower ΔE values indicate a smaller colour discrepancy between the restoration and the surrounding tooth structure and were interpreted as better colour matching. Higher ΔE values indicate greater perceptible colour differences.
Baseline, 3 months, 6 months, 12 months
Photographic/ Digital Colour stability
大体时间:Baseline, 3 months, 6 months, 12 months
For the assessment of colour stability, ΔE values obtained at different follow-up intervals were compared over time at baseline (ΔE0), 3 months (ΔE₁), 6 months (ΔE₂) and 12 months (ΔE₃). Small differences in ΔE values across these time points were interpreted as indicating greater colour stability.
Baseline, 3 months, 6 months, 12 months
