NCT06183320
Treatment clinical trial, randomized, controlled, parallel, double-blinded, with two groups, that aims to evaluate the best application strategy when using a flowable bulk fill composite (Opus Bulk Fill Flow APS, FGM, Brazil) in class II cavities. Volunteers will be selected and recruited, following inclusion criteria and pre-established exclusion criteria. All volunteers will be informed and sign a term of clarification and consent. 38 enrolled patients will receive 76 Class II dental restorations, made in two different ways, one from each experimental group. Authors will perform restorations with an incremental composite (Vittra APS - FGM) associated with a bulk-fill flowable composite (Opus Bulk Fill Flow APS - FGM), in class II cavities, exposing (Group BP) or not (Group IP) the bulk fill flowable composite to the cavosurface angle on the proximal wall of the restorations. In both groups, Opus Bulk Fill Flow APS resin will be used in the bulk technique with up to 5mm depth increments, leaving 1 mm in the occlusal for incremental Vittra APS composite resin. Immediate post-operative tooth sensitivity will be evaluated after one week. Restorations will be evaluated every 6 months for pain assessment, shape, fractures, staining or recurrent caries, using FDI scores. To determine in which group each tooth will be enrolled, the authors will randomize the teeth.

NCT07265804
This study evaluated the regenerative outcomes of immature permanent teeth with necrotic pulps treated using three scaffold types-blood clot, platelet-rich fibrin (PRF), and concentrated growth factor (CGF)-combined with either 5% or 17% EDTA as the final irrigant. Thirty teeth were randomly assigned to six treatment groups and followed clinically and radiographically for 12 months. Cone-beam computed tomography (CBCT) was used to assess root development parameters, including root length increase, apical diameter change, hard tissue formation, and periapical lesion volume. Clinical assessments included pain, swelling, sinus tract formation, percussion sensitivity, and pulp sensitivity testing. The study aimed to determine whether different scaffold materials and EDTA concentrations influence regenerative healing responses in immature necrotic teeth.

NCT06615544
The overall aim of this study is to evaluate the clinical performance and safety of the new dental dual-cure adhesive for luting indirect ceramic restorations (inlays and onlays). The primary aim is to determine the rate of postoperative hypersensitivity occurrence after using the new adhesive for the placement of indirect restorations. The secondary objective of this study is to assess the long-term clinical performance of the new adhesive in terms of marginal quality, retention/fracture rate of the ceramic restorations, and vitality/fracture rate of the restored teeth.
NCT06918639
Preservation of pulp tissue would allow it to continue to exert its defensive and physiological functions and more tooth tissue would be preserved, leading to less weakening of the tooth. In addition, root canal treatment is a more complex therapeutic process that requires the use of more instruments, more time and more visits. To date, most clinical studies that have evaluated the success of pulpotomy treatments have been conducted on teeth with immature apexes. More studies are needed to evaluate VPT success in the permanent dentition in the long term. In accordance with the above, the main objective of the study will be to determine the success of partial or total pulpotomy treatment in permanent teeth (\>18 adults) with a closed apex and symptoms compatible with irreversible pulpitis. At the same time, the association of factors related to the patient, the treated tooth and specific treatment factors with the success of pulpotomies will be determined. On the other hand, the patient, perception and satisfaction with the treatment received will be evaluated. All treatments (pulpotomies and restorations) will be carried out by the principal investigator. After recording the preoperative data, clinical and radiographic examination, a diagnosis will be made according to the classification of Wolters and collaborators , which will also guide us in the choice of pulp treatment: PP o CP Partial pulpotomy or complete pulpotomy. The maximum pulp haemostasis time will be 10 minutes. In both treatments, in the same appointment, the definitive restoration of the tooth will be carried out. The evaluations will be performed at one week, 3 , 6 and 12 months postoperatively. This evaluation shall be performed by an examiner who shall be different from the one performing the treatment. The main outcome of the present study will be the determination of the success of the pulpotomies. \- Is vital pulp therapy a highly successful treatment for teeth with irreversible pulpitis?. Outcome measure 1: Success rate of vital pulp therapy \- Do patients feel satisfied with this conservative pulp treatment? Outcome measure 2: Patient´s satisfaction with vital pulp therapy

NCT06273410
Despite significant advances in composite materials, they are still perceived as technique-sensitive and exhibit failure related to excessive wear and polymerization shrinkage. Cention N is a recently introduced alkasite restorative that contains special reactive fillers. Its application in restorative dentistry may be significant, promoting remineralization of carious lesions \& reduction of polymerization shrinkage. The study will aim to compare the clinical performance of Cention N (with and without adhesive) and composite resin (Filtek Bulk Fill) in class I restorations using FDI criteria. Thirty-six class I cavities will be selected and equally allocated into 3 groups: Group I (n=12): (Cention N with adhesive), Group II (n=12): (Cention N without adhesive) \& Group III (n=12): composite resin (Filtek Bulk Fill) in class I cavities. Patients will be followed up at 1 week 3, 6, and 12 months and evaluated using the FDI criteria. Postoperative sensitivity, staining, and recurrent caries will be evaluated in this clinical trial.

Objective: To evaluate the clinical performance of indirect resin composite restorations, which were luted with two different resin cement, in posterior teeth for up to 2 years. Methods: From February 2017 to May 2017, a total of 43 patients (21 men, 22 women; mean age.), received 48 onlay restorations made of laboratory-processed indirect composite (Gradia, GC, Japan). 27 onlay restorations (Group A) were luted using an etch and rinse resin cement (Variolink II, Ivoclar Vivadent) and 22 onlay restorations (Group B) were luted using a self-adhesive resin cement (Relyx U200, 3M ESPE). Patients were followed until May 2019. Two independent calibrated examiners evaluated the restorations at 3-time points: 2 weeks after placement (baseline), 6 months, and then annually, using the modified USPHS/FDI criteria.
NCT03933176
This randomized, multi-centric, controlled clinical trial will assess the effectiveness of a simplified restorative protocol used after the selective carious tissue removal in posterior teeth presenting deep carious lesions. Only a regular bulk-fill composite will be used in the simplified restorative protocol following the application of universal adhesive. A liner with resin-modified glass ionomer will be used over the pulpal floor before the composite placement in the control group. The longevity of restorative procedures and post-operative sensitivity were defined as the main and secondary outcomes.
