    Effect of mouthwashes on the discolouration of restorative materials commonly used in paediatric dentistry
    (Springer, 2018) Ulusoy, N. B.; Arikan, V.; Oba, A. Akbay
    This was to investigate the effects of Klorhex, Tantum Verde, Kloroben, and Listerine on the discolouration of composite resin, compomer, giomer, and resin-modified glass ionomer. Fifty disc-shaped specimens from each restorative material (n = 50) were prepared; initial colour values were measured with a spectrophotometer. Forty specimens from each group were placed in the four different types of mouthwashes (n = 10), while the remaining 10 specimens were immersed in distilled water for 2 min, twice a day for a period of 3 weeks. Colour change (Delta E*) values were obtained and the results were evaluated statistically. The Delta E* of composite resin in Klorhex (0.84 +/- 0.37) was significantly lower than that of the other mouthwash groups. Moreover, composite resin showed the least colour change when compared with the other materials in all four mouthwashes. Resin-modified glass ionomer values were significantly higher in Tantum Verde (6.36 +/- 2.82) when compared with the other mouthwashes (p < 0.05). Clinically appreciable discolourations were observed in the resin-modified glass ionomer specimens placed in Tantum Verde and Listerine. Nano-filling composite resins are the most successful aesthetic restorative materials, whereas the commonly used resin-modified glass ionomers exhibit more aesthetically divergent results following the use of mouthwashes.

    Treatment of horizontal root fractured central incisors and 30 months follow up: 2 case reports
    (Ariesdue Srl, 2014) Arikan, V.; Celikten, Z. K.; Sari, S.
    Background Horizontal root fractures are rare in comparison to other types of injuries and according to the literature account for between 0.2% - 7% of all traumatic tooth injuries. Case reports Case 1: A 12-year-old girl was referred to our clinic with a complaint of tenderness and mobility as a result of an orofacial injury in her permanent upper left central incisor. A horizontal fracture was diagnosed on the middle third of the root during radiographic examination. Case 2: A 12-year-old boy was referred to our clinic with an injury to his upper left central incisor. During radiographic examination a horizontal fracture was diagnosed on the middle third of the root. Semirigid splints were applied to the teeth for 4 weeks without further treatment in both of the cases and they were followed-up for 30 months. At the end of the 30th month, the teeth were vital and they had no clinical signs nor symptoms. Also the radiographic examination showed healing with hard tissue in the fracture line for both of the cases. Conclusion Using semi-rigid splints without any further treatment resulted with hard tissue healing in both of the cases and was successful for the treatment of horizontal root fractures.
