Clinical Study Evaluating Solventum™ Vitrebond™ Pulp Protect Liner/Base for Direct Capping of Pulpal Exposure

A Multi-site, Single-Arm Clinical Study Evaluating the Efficacy of Solventum™ Vitrebond™ Pulp Protect Liner/Base for Direct Capping of Pulpal Exposure Due to Trauma, Deep Caries, or Mechanical Etiology Under Dental Restorations

This research study is looking at the safety and effectiveness of Solventum™ Vitrebond™ Pulp Protect Liner/Base for direct pulp capping (DPC) on permanent teeth that have pulp exposure due either to deep cavities, trauma, or other accidental causes. Dental pulp is the part of the tooth that contains the nerves, blood vessels, and cells that keep teeth healthy. The DPC procedure is done by dentists to help preserve tooth health if there is pulp exposure during the tooth restoration or due to trauma. Participants must have at least one permanent tooth with pulp exposure that needs DPC to be eligible for the study.

• Intervention / Treatment: Device: Vitrebond™ Pulp Protect Liner/Base

Detailed Description

This is a multi-site, single-arm, prospective clinical study evaluating Solventum™ Vitrebond™ Pulp Protect Liner/Base treatment for direct pulp capping on permanent teeth. Vitrebond™ Pulp Protect Liner/Base is a new product designed to be placed under dental fillings that can be used as a "Liner/Base" to create a lining between the tooth and the filling to reduce sensitivity, and for direct pulp capping if there is a small amount of dental pulp exposed during the restoration.

The purpose of this clinical study will be to assess the effectiveness and safety of Vitrebond™ Pulp Protect for direct pulp capping on permanent teeth that have pulp exposure due either to deep cavities, trauma, or other accidental causes. The primary objective is to evaluate Vitrebond™ Pulp Protect Liner/Base in maintaining pulp vitality (a measure of tooth health) when used for pulp capping, measured at 1-year post-restoration. The secondary objective of this study is to evaluate treated teeth for abnormal clinical signs or symptoms for up to 5 years after treatment to assess long-term safety and effectiveness. The success of Vitrebond™ Pulp Protect for direct pulp capping in this single-arm clinical study will be determined based on an assessment of pulp vitality one year after restoration compared to a pre-specified performance goal derived from literature using calcium hydroxide as the reference comparator.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Pulp Vitality at 1-year	Pulp vitality, assessed by pulp sensibility testing using a refrigerant spray intended for dental use. A positive response from the pulp sensibility test is indicative of the pulp vitality of the tooth (primary endpoint). Categories for pulp vitality will include: Vital pulp (normal): Positive response from the pulp sensibility test that subsides within 5 seconds.; Reversible pulpitis: Positive response from pulp sensibility test that lasts greater than 5 seconds up to approximately 30 seconds.; Irreversible pulpitis: Prolonged positive response from pulp sensibility test that lasts more than approximately 30 seconds.; Non-vital pulp: Negative response from the pulp sensibility test.	1 year post-restoration

The American Academy of Periodontology definition of tooth mobility is the movement of a tooth in its socket resulting from an applied force. Categories for pathological tooth mobility using the Miller's tooth mobility index will include: Class 0: normal (physiologic) movement when force is applied; Class 1: < 1 mm (horizontal)a. mobility greater than physiologic; Class 2: ≥1 mm (horizontal),tooth can be moved 1 mm or more in a lateral direction (buccolingual or mesiodistal); andinability to depress the tooth in a vertical direction (apicocoronal); Class 3: ≥1 mm (horizontal and vertical)tooth can be moved 1 mm or more in a lateral direction (buccolingual or mesiodistal); andability to depress the tooth in a vertical direction (apicocoronal)	baseline, 3 months, 6 months, and 1, 2, 3, 4, and 5 years post-restoration
Spontaneous pain	Spontaneous pain not due to a stimulus will be self-assessed by subjects for each study tooth at scheduled visits. The baseline spontaneous pain assessment should be conducted a minimum of 3 hours after completing the restoration to allow time for the anesthesia to wear off. The baseline assessment may be conducted via phone to ask the subject if they are experiencing any spontaneous pain in the study tooth and must be completed within 1 week of the tooth restoration. The absence of spontaneous pain is desired. Spontaneous pain is defined as prolonged intense pain that doesn't respond to over-the-counter pain medication, and/or pain that wakes you up from sleep. Categories for spontaneous pain will include: Presence of spontaneous pain; Absence of spontaneous pain	baseline, 3 months, 6 months, and 1, 2, 3, 4, and 5 years post-restoration
