This study evaluated the bond strength of different adhesive agents to TheraCal LC and mineral trioxide aggregate (MTA) and examined the morphologic changes of these materials with different surface treatments. A total of 120 specimens, 60 of MTA Angelus (AMTA), and 60 of TheraCal LC, were prepared and divided into six subgroups according to the adhesive agent used; these agents included Scotchbond Multipurpose, Clearfil SE Bond, Clearfil Protect Bond, Clearfil S Bond, OptiBond All-in-One, and G-aenial Bond. After application of adhesive agents, Filtek Z250 composite resin was placed onto the specimens. Shear bond strengths were measured using a universal testing machine, followed by examination of the fractured surfaces. The surface changes of the specimens were observed using scanning electron microscopy. Data were compared by two-way analysis of variance. Although no significant differences were found among the bond strengths of different adhesives to AMTA (p = 0.69), a significant difference was found in terms of bond strengths of different adhesives to the TheraCal LC surface (p < 0.001). The total-etch adhesive system more strongly bonded to TheraCal LC compared to the bond with other adhesives. TheraCal LC bonded significantly more strongly than AMTA regardless of the adhesive agents tested. Resin-modified calcium silicate showed higher bond strength than AMTA in terms of the composite bond to these materials with different bonding systems. On the other hand, the highest shear bond-strength values were found for composite bonds with the combination of TheraCal LC and the total-etch adhesive system.

Background/Aim Traumatic dental injuries are among the most serious dental public health problems in children. The aim of this retrospective study was to evaluate the dental trauma profile of primary and permanent teeth among children aged 0–15 years who presented to a university hospital. Material and Methods The study included 650 patients (1,000 primary and permanent teeth) who presented with a history of dental trauma to the Department of Pediatric Dentistry, Faculty of Dentistry, Erciyes University between 2016 and 2019. Traumatized teeth were assessed according to the Andreasen classification. The following information was recorded: age, gender, teeth affected by trauma, etiologies of trauma, place and season of trauma, type of trauma, type of treatment, and time between the trauma and treatment. Results In total, 650 patients (240 females, 410 males) and 1,000 incisors (212 primary teeth, 788 permanent teeth) were evaluated. The average age of the patients was 8.89 ± 3.41 years, and dental injuries were more frequent between 8 and 10 years of age. The maxillary central incisors, both primary (40.1%) and permanent (42.8%), were the most frequently affected teeth. The main cause of traumatic dental injuries was falls. Most accidents occurred at school and home. The most common type of dental injuries recorded was luxation injuries in the primary teeth (21.5%) and enamel‐dentin fractures (35.9%) in the permanent teeth. Only 48 teeth were treated during the first hour after injury. Conclusions The most common type of traumatic injury affecting permanent teeth was enamel‐dentin fractures, and primary teeth were luxation injury. Only 4.8% of teeth were treated within the first hour after trauma.

Although there was no significant difference in the development of dental caries or the prevalence of enamel defects between children with congenital heart disease and healthy children, the care score was low in children with congenital heart disease. In addition, children with congenital heart disease had a higher rate of pulled primary teeth and delayed treatment of decayed teeth.
