Molar-incisor hypomineralization (MIH) can result in minor injuries or major structural loss, especially in incisors and molars. Patients with MIH seek dental treatment early, usually in childhood. Choosing the best treatment option during this stage can be a challenge. Because these patients still present a mixed dentition, the use of prosthetic appliances is not usually the best option. This case report with a 7-year follow-up presents an overview of a conservative approach for the restoration of teeth affected by MIH...

The purpose of this study was to compare the depths of cure of a proximal box preparation filled in bulk with various approaches: filled with a bulk-fill or conventional composite; placed with a new perforated metal matrix, a traditional metal matrix, or a clear matrix; and polymerized with either occlusal-only or tri-sited light curing. After tri-sited curing, the use of the new perforated metal matrix band resulted in a depth of cure that was not significantly different from that achieved with the use of metal bands (removed during curing) or transparent matrix bands...

This study evaluated the effect of 3 commercially available calcium silicate materials (CSMs) on pH changes in simulated root resorption defects. Simulated root resorption defects were prepared on the facial root surface of 40 mandibular premolars. The depth of each defect was individually calculated to standardize the remaining dentin thickness to 1 mm. Prepared canals were obturated with the 3 CSMs. Ten specimens were kept as controls, filled with unbuffered normal saline. The pH measurements were taken at 1 hour, 6 hours, 1 day, 1 week, 2 weeks, 3 weeks, 1 month, and 2 months...

This study evaluated the effect of fiber inserts combined with composite resins on enamel and dentin margin microleakage. The fiber inserts were used with high- (x-tra fil) and low-viscosity (x-tra base) bulk-fill composite resins and as well as conventional composite resins (Grandio and Grandio Flow). In 96 sound, recently extracted molars, 2 standardized Class II cavities were prepared. The teeth were randomly divided into 8 groups of 12 teeth each, based on composite resin type and presence or absence of fiber inserts: groups 1 and 2, x-tra fil with and without fiber inserts, respectively; groups 3 and 4, x-tra base with and without fiber inserts; groups 5 and 6, Grandio with and without fiber inserts; and groups 7 and 8, Grandio Flow liner (gingival floor)/Grandio (remainder of cavity) with and without fiber inserts...

This case report describes the consequences of delayed (24 hours) reimplantation of an avulsed maxillary central incisor, findings over a 4-year follow-up period, and the management of ankylosis during facial growth. After a traumatic event, a 10-year-old boy was taken to a hospital emergency department due to injuries to his face, including avulsion of the maxillary left central incisor. Despite the short amount of time before arriving at the hospital (10 minutes) and use of the correct storage medium (milk), the tooth was not reimplanted, and the parents did not receive instructions to seek dental treatment...

Bioceramic materials are at the forefront of modern dentistry. Bioactive bioceramic endodontic materials promote pulpal and periapical tissue healing and are easy to use. Dentists can choose among many endodontic materials, depending on their needs. This article highlights the major differences among commercially available bioactive tricalcium silicate bioceramics, commonly known as mineral trioxide aggregate materials, to enable dentists to make appropriate decisions in the selection of these materials.

To avoid complications, the intimate relation between the maxillary sinus and dental roots deserves attention during surgical procedures. Accidental introduction of foreign bodies, such as dental implants, may irritate the maxillary sinus mucosa, causing sinusitis. Cone beam computed tomography (CBCT) has been proven to be suitable for diagnosis in these cases by providing the exact location of the foreign body. The present article reports 3 cases of foreign bodies inside the maxillary sinus associated with inflammatory processes...

This in vitro study evaluated the marginal microleakage of a bioactive restorative with other restorative materials in standard Class V preparations. Sixty previously extracted, noncarious human molars were randomly assigned to 3 experimental groups (n = 20): a bioactive composite resin, a universal hybrid composite resin, and a resin-modified glass ionomer restorative. Class V cavities were prepared on the facial or lingual surface of each tooth so that coronal margins were located in enamel and apical margins in cementum (dentin)...

Endodontic management of 3-rooted maxillary premolars is a challenge due to their complex anatomy and narrow root canal walls. This study aimed to evaluate, by microcomputed tomography (μCT), the apical enlargement and centering ability promoted by hand, rotary, and reciprocating instrumentation in 3-rooted maxillary premolars. Eighteen teeth were divided into 3 groups (n = 6) according to the preparation technique: crown-down hand, rotary, and reciprocating instrumentation. Instruments with similar apical diameters were used (25 and 40 mm for buccal and palatal canals, respectively)...

Dental care providers are likely to see patients who take bisphosphonates for various medical conditions, including osteoporosis, bony metastatic tumors, multiple myeloma, breast cancer, and prostate cancer. Bisphosphonates accumulate in areas of high bone turnover, leading to suppression of bone turnover and the aging of keratocytes. These adverse effects predispose the maxillary and mandibular bone to development of medication-related osteonecrosis of the jaw (MRONJ), specifically among oncology patients treated with intravenous bisphosphonate therapy...

The aim of this study was to evaluate the bond strength between an yttria-stabilized tetragonal zirconia polycrystal (Y-TZP) ceramic and a luting agent when submitted to plasma etching surface treatment before and after thermocycling (TC) with 3000 cycles of 5°C-55°C. The null hypothesis was that the surface treatments and thermocycling would not influence the bond strength. A total of 160 Y-TZP ceramic blocks in 2 sizes (10 size 1 and 10 size 2 blocks in each group) were distributed into 8 groups: group C (control), no surface treatment; group C-TC, TC without prior surface treatment; group SAO, sandblasting with aluminum oxide (Al2O3); group SAO-TC, sandblasting with Al2O3 followed by TC; group SAOS, sandblasting with silica-coated Al2O3; group SAOS-TC, sandblasting with silica-coated Al2O3 followed by TC; group PE, plasma etching; and group PE-TC, plasma etching followed by TC...
