Bioactive Basics: What You Need to Know

Bioactive materials help stimulate the natural remineralization process. In the presence of saliva, they elicit a biological response that forms a layer of apatite and a natural bond between the material and the tooth.*

Pulpdent’s research focuses on developing bioactive materials that imitate the physical and chemical properties of teeth, help neutralize conditions that cause dental caries, and maximize the potential for remineralization.

ACTIVA BioACTIVE materials behave favorably in the moist oral environment. They participate in a dynamic system of ionic exchange with saliva and tooth structure, continuously releasing and recharging calcium, phosphate and fluoride and responding to pH changes in the mouth. When the pH is low, the demineralization process releases calcium and phosphate ions from both the teeth and ACTIVA. When the pH increases, these ions are available to combine with the fluoride ions in our saliva and precipitate onto the teeth in the form of acid-resistant fluorapatite.

The addition of a patented rubberized-resin molecule to the ACTIVA resin matrix absorbs stress and shock and delivers unprecedented toughness and fracture resistance.

ACTIVA BioACTIVE materials are strong, esthetic and durable, and offer an
alternative to traditional composites, which are strong and esthetic but are passive and without bioactive potential, and to glass ionomers, that release a significant amount of fluoride but have poor esthetics and undesirable physical properties.

ACTIVA Receives 2019 Top Bioactive Product Award from The Dental Advisor

ACTIVATM BioACTIVE-RESTORATIVETM received the Top Bioactive Product Award from THE DENTAL ADVISOR for 2019. The original bioactive composite continues to impress dentist evaluators.

ACTIVA BioACTIVE responds to pH changes in the oral environment by releasing and recharging calcium, phosphate and fluoride. This unique chemistry supports the natural remineralization process and helps form a seal between the material and the tooth. Unlike traditional composites, which are generally hydrophobic and brittle, ACTIVA BioACTIVE contains a shock-absorbing rubberized resin that resists chipping and wear. Dentist evaluators found that “the esthetics were excellent at 2 years.”

“To be considered for an award, products must receive an excellent rating by THE DENTAL ADVISOR, as well as stand out from all others in the market place,” said Dr. Sabiha Bunek, The Dental Advisor’s Editor-in-Chief. ACTIVA BioACTIVE responds to pH cycles and an evaluator for THE DENTAL ADVISOR noted that “the uptake of Calcium, Phosphate and Fluoride could have a positive effect.” (The Dental Advisor Evaluator Comments, Top Product 2018).

In 2017, The Dental Advisor rated ACTIVA™ BioACTIVE-RESTORATIVE™ as excellent, with 5 plus (+++++) and a 98% clinical performance rating after the second year of a long-term clinical evaluation of 194 anterior and posterior restorations. Dentist evaluators used the material for a variety of applications, including 1, 2, 3 and 4 surface restorations and core build-ups.

ACTIVATM BioACTIVE is an esthetic bioactive composite that imitates the physical and chemical properties of teeth. It contains no Bisphenol A, no Bis-GMA and no BPA derivatives.

Direct from the Operatory: Class II Restoration with ACTIVA BioACTIVE-RESTORATIVE

By: Dr. Jack Griffin

The patient presented with interproximal decay between the bicuspid and molar (Figure 1) and needed Class II restorations on both teeth.

Figure 1. Shows interproximal decay between the bicuspid and molar.

Using an Isolite system to ensure proper isolation, I placed wedges before drilling. This technique creates pressure on the PDL, helping to protect the gingiva while also making it easier to place a sectional matrix. I placed a caries indicator to make decay removal more efficient by staining debris, denatured collagen, decalcification, and decay.

Figure 2. Shows placement of sectional matrix and separating ring.

Afterwards I removed the pre-operative wedges, placed a sectional matrix and a separating ring (Figure 2). A total etch with 37% phosphoric acid was done for 15 seconds, rinsed thoroughly and a universal bonding agent placed predominantly on the enamel. The restoration was bulk filled using ACTIVA BioACTIVE-RESTORATIVE (Figure 3) and then light cured from the lingual, buccal and then occlusal sides.

Figure 3. Shows bulk filling with ACTIVA BioACTIVE-RESTORATIVE using the convenient bendable metal cannula.

After curing, I removed the matrix materials and contoured the restoration with a round bur, light pressure, and water. The occlusion was checked and adjusted before smoothing and polishing the moist tooth with a rubber composite polishing cup. The final restoration meets the aesthetic demands of the patient while providing the ionic exchange to combat long-term restoration failure.

Direct from the Operatory: Embrace Pit & Fissure Sealant

by Dr. Josh Wren 

A 7-year-old male patient came to my clinic for a 6-month recall examination and cleaning. We had placed two occlusal-lingual resin restorations one year earlier to repair carious lesions on teeth # A and J. There was organic debris present in all pit and fissures of the fully erupted 6-year molars (Figure 1), but not in the primary teeth. When questioned, the caregiver stated that the patient brushes his teeth with no parental supervision and had brushed just before coming to this exam. 

Figure 1. Organic or food debris is often found on examination of first permanent molars despite good hygiene for other teeth.

All first permanent molars were free of decay, and after consent was obtained, the patient was prepared for sealants on all the permanent molars. The Isolite device was chosen for its ability to treat opposing molars simultaneously. A thorough air-water blast was used to assess if a fissurotomy was indicated or if we should proceed with a non-abraded sealant procedure. 

Thorough cleaning and air-water blast were not sufficient to remove the organic debris from the permanent molars, so I chose a 330 bur to lightly prepare each groove (Figure 2).

Figure 2. Shows preparation of all grooves in a lower left first permanent molar after gentle removal of debris using a 330 bur.

This technique requires only a gentle approach to round the deep grooves, not the normal preparation for a cavity. After preparation, 37% phosphoric acid was applied to the enamel for 20 seconds, rinsed, and lightly dried, removing all surface water, but not desiccating the tooth. Embrace WetBond Pit and Fissure Sealant was applied to the grooves and cured for 20 seconds (Figure 3).

Figure 3. 37% phosphoric acid was applied for 20 seconds, rinsed and lightly dried, and then Embrace WetBond Pit and Fissure Sealant was applied and cured.

An explorer examination was performed to check the margins and attempt to remove the sealant from the tooth-sealant interface. No detectable margin was present (Figure 4). 

Figure 4. Final result. Smooth margins of Embrace sealant are undetectable with an explorer.
