It was revealed that although the most frequent type of injury in permanent dentition was uncomplicated crown fracture, the root canal treatment was the most common treatment in permanent dentition. This finding suggests that when the checkup time after the injury was delayed, the pulp could lose vitality. This finding reveals that it is important to inform the parents about dental trauma and the importance of bringing their children fast to a dentist in trauma cases.

The aim of the study was to evaluate the efficacy of plaque removal of three different toothbrushes on mentally disabled children in two different age groups. A manual triple-headed brush (SuperBrush; Dento Co. AS [junior, regular]) compared with a new manual toothbrush (CrossAction; Oral-B [35 compact, 40 regular]) and an electric toothbrush with an oscillating rotating head (Braun Plaque Control 3D [Braun 3D]; Oral-B [D15525]). Fifteen children aged 6-12 (Group A) and 15 children aged 13-18 (Group B) with mild mental disabilities participated in the single-blind clinical study. To obtain a plaque-free condition at baseline, professional tooth-cleaning was performed on each participant. After instructions on how to use the toothbrushes, each group started the experiment. After 1 week of application, the Quikley Hein (QH) plaque index and the approximal plaque index (API) were used to assess the oral hygiene status of each participant. This was followed by a week of recess before each group switched to the next type of toothbrush. The study lasted for 5 weeks. Compared to the two other brushes, the Braun 3D was more effective in removing plaque (means of QHI: 1.54 (Braun 3D), 1.77 (SuperBrush), and 2.15 (CrossAction) in total; means of API 1.37 (Braun 3D), 1.52 (SuperBrush), 1.94 (CrossAction). The study indicated that the electric toothbrush is the most effective for removing dental plaque in mentally disabled children, whereas the SuperBrush is a good alternative.

This 12-week clinical study evaluated the impact of 10% CPP-ACP and 5% sodium fluoride varnish regimes on the regression of nonorthodontic white spot lesions (WSLs). The study included 21 children with 101 WSLs who were randomised into four treatment regimes: weekly clinical applications of fluoride varnish for the first month (FV); twice daily self-applications of CPP-ACP paste (CPP-ACP); weekly applications of fluoride varnish for the first month and twice daily self-applications of CPP-ACP paste (CPP-ACP-FV); and no intervention (control). All groups undertook a standard oral hygiene protocol and weekly consultation. Visual appraisals and laser fluorescence (LF) measurements were made in weeks one and twelve. The majority of WSLs in the control and FV groups exhibited no shift in appearance, whereas, in the CPP-ACP and CPP-ACP-FV groups, the lesions predominantly regressed. The visual and LF assessments indicated that the extent of remineralisation afforded by the treatments was of the following order: control ~ FV < CPP-ACP ~ CPP-ACP-FV. Self-applications of CPP-ACP paste as an adjunct to standard oral hygiene significantly improved the appearance and remineralisation of WSLs. No advantage was observed for the use of fluoride varnish as a supplement to either the standard or CPP-ACP-enhanced oral hygiene regimes.
