“…In vitro studies showed BPA and BPA derivatives were detected in saliva. 49,50 These results in line with numerous in vivo studies that tested the BPA and BPA derivatives content in saliva. 48,51,52 Nevertheless, some studies detect the BPA decreased in saliva after placement of dental sealants during several weeks observation period.…”

The utility of dental materials to posing oral diseases have impact in the risk of Bisphenol A (BPA) exposure which can be harmful to human organs. BPA used in dentistry is related to the production of polycarbonate plastics and epoxy resins. For instance, composite filling materials and dental sealant are containing BPA that can promote risk to endocrine-disrupting, estrogenic effect, and renal exposure. The current study is reviewing the BPA exposures of dental materials and it impact risk to the systemic health. This systematic review critically evaluates, and the information gathered form several literatures. The source of these articles was Pub Med and Web of Science, search done with the following terms: BPA of dental materials, BPA exposure, BPA and health risks, BPA, and oral health. BPA exposure found in oral mucosa and saliva after the application of BPA-containing dental materials. BPA derivatives used in dental products have not been evaluated for the endocrine disruptor, estrogenicity. BPA exposures can be absorbed through the oral mucosa and may lead to internal exposures the absorption of BPA from the gastrointestinal tract. Manufacturers should be required to report complete information on the chemical composition of dental materials and strict precaution application techniques must be considered by the practitioner.

“…It has been confirmed that low pH negatively affects the release of BPA. Therefore, frequent exposure to low pH due to consumption of various beverages after sealant treatment may negatively affect the chemical stability of the sealant in the oral cavity [59]. Composite materials may be considered a potential long-term source of BPA and therefore should not be neglected when assessing overall exposure to endocrine disrupting chemicals.…”

Pierre Robin Sequence and 3D Printed Personalized Composite Appliances in Interdisciplinary Approach

et al. 2022

This paper introduces a complex novel concept and methodology for the creation of personalized biomedical appliances 3D-printed from certified biocompatible photopolymer resin Dental LT Clear (V2). The explained workflow includes intraoral and CT scanning, patient virtualization, digital appliance design, additive manufacturing, and clinical application with evaluation of the appliance intended for patients with cranio-facial syndromes. The presented concept defines virtual 3D fusion of intraoral optical scan and segmented CT as sufficient and accurate data defining the 3D surface of the face, intraoral and airway morphology necessary for the 3D design of complex personalized intraoral and extraoral parts of the orthopedic appliance. A central aspect of the concept is a feasible utilization of composite resin for biomedical prototyping of the sequence of marginally different appliances necessary to keep the pace with the patient rapid growth. Affordability, noninvasiveness, and practicality of the appliance update process shall be highlighted. The methodology is demonstrated on a particular case of two-year-old infant with Pierre Robin sequence. Materialization by additive manufacturing of this photopolymer provides a highly durable and resistant-to-fracture two-part appliance similar to a Tübingen palatal plate, for example. The paper concludes with the viability of the described method and material upon interdisciplinary clinical evaluation of experts from departments of orthodontics and cleft anomalies, pediatric pneumology and phthisiology, and pediatric otorhinolaryngology.
