QUESTIONS from Dental providers & Answers– DENTOCLUDE F

DentoClude F is a USFDA approved novel/proprietary finely ground bioglass  indicated to use as a desensitizing agent for dentin surfaces by blocking dentin tubules to help prevent micro-leakage and to use under direct or indirect restorations following dentin etch and prior to dentin adhesive application. 

Inlays and onlays are cemented in the mouth using adhesive resin luting cements. These materials are placed in the inlay/ onlay and placed onto the prepared tooth.  Bonding agents can be applied to dentine before cementation of inlays and onlays.

Literature supports the usage of bioactive glasses in various aspects of dentistry including dental restorative materials. Many luting cements and dental adhesives were enhanced with bioglass for its biocompatibility and to decrease the microleakage and improve the bond strength without compromising their mechanical properties.

In-vitro study demonstrated that Bioactive glass powder added to the resin-dentin bonded interface that previously has been shown to reduce leakage does not decrease the bond strength. Indeed it showed superior bond strength compared to the control by three times. No adhesive failure was seen. (Reference: Sally Marshall paper/ slides)

A Study was conducted to compare the effect of bioactive glass, hydroxyapatite, and diode laser desensitization on shear bond strength of resin composites to dentin at different time intervals. Seventy-two caries-free maxillary premolars were selected. Buccal surfaces were flattened to expose dentin. Teeth were divided into four groups according to treatment modality (control with no pre-treatment, Tooth paste with bioactive glass, Hydroxyapatite Desensitizer, diode laser). Bonding was performed using self-etch adhesive followed by composite build up. Universal testing machine was used to determine shear bond strengths immediately after bonding, after 3 months, and 5 months storage in artificial saliva. Pre-treatment with BG and hydroxyapatite desensitizers increased, whereas diode laser decreased mean shear bond strength of composite to dentin as compared to control group. No statistical significant difference in shear bond strength values was seen in groups after storage.

Effect of Desensitization Using Bioactive Glass, Hydroxyapatite, and Diode Laser on the Shear Bond Strength of Resin Composites Measured at Different Time Intervals: An In vitro Study. Contemp Clin Dent. 2017 Apr-Jun;8(2):244-247. doi: 10.4103/ccd.ccd_155_17. PMID: 28839410; PMCID: PMC5551329.

DentoClude F can be used immediately after self-etchant adhesive as the dental bonding composition dissolves the smear layer, demineralizes the dentin to expose dentin matrix and primes the etched dentin surface. In addition, the bioactive glass and adhesive penetrate the demineralized dentin to form the hybrid layer. Then the dental bonding can be cured.

Energy-dispersive x-ray analysis/EDX maps of a study conducted to test the hypothesis that the presence of bioactive glass, which is known to precipitate hydroxyapatite when placed in aqueous environments that contain calcium and phosphate, will reduce leakage of resin-bonded dentin showed that bioactive glass particles were embedded in the dentin to a depth of 5-10 µm below the surface. The maps further suggested that the materials are present in both the adhesive and the dentin itself.

A review of the present literature supports clinical applications of prefabricated implants made of Bioglass ceramics, as has been used in calvarial and midface bone reconstructions as well as for the repair of orbital floor fractures. Also, present experience with Bioglass in particulate form, preferably mixed with small amount of autogenous bone, support the convenience of this biomaterial over alternate forms of synthetic graft materials. 

 A 5-year evaluation on Bioglass cones was conducted to examine the effectiveness of Bioactive cones as space fillers after removal of tooth roots to delay the resorption of alveolar ridges (Stanley et al). High rate (85.7%) of cone retention after 5 y Placement of Bioglass into fresh sockets promoted alveolar ridge preservation and is said to be a material of choice for endosseous ridge maintenance implants to prevent alveolar ridge resorption.

Retrospective review was conducted to evaluate Particulate bioglass as a grafting material in the treatment of periodontal intrabony defects. Results demonstrated the efficiency of Bioactive glass as an adjunct to conventional surgery in the treatment of intrabony defects.                                                    

Histological observations on biopsies harvested following sinus floor elevation using a bioactive glass material of narrow size range were made to evaluate the bone augmenting capacity of Bioactive glass particles in human sinus floor elevations. Results demonstrated that a 1:1 mixture of autogenous bone/Bioactive glass particles seemed a promising alternative to autogenous bone only, when low amounts of bone tissue are available for sinus augmentation
