Task: Question Answering
Input (English): Context: AIM, MATERIAL AND METHODS: Endodontic treatment of a total of 303 teeth with pulpitis and periodontitis was performed with a new calcium-carbamide-formaldehyde paste. In three children with fractured teeth with complications, the applied treatment was combined (2 teeth with apical osteotomy and 1 with cystectomy). Control examinations were carried out at months 6, 12 and 24 and clinically healthy teeth and teeth with complications were registered.', 'In the pulpitis group the clinically healthy teeth were 97.55% +/- 1.08 at the 6th month; 96.85% +/- 1.26 at the 12th month and 92.92% +/- 2.41 at the 24th month. In teeth with periodontitis 91.56% +/- 3.05 were clinically healthy at the 6th month; 93.83% +/- 2.67 at the 12th month and 98.03% +/- 1.98 at the 24th month. No statistical significance of the differences between pulpites and periodontites was found (P > 0.05). Recovery of the bone structure was observed in the teeth with combined endodontic and surgical treatment at the 12th month.\Question: Do endodontic treatment of permanent teeth in children with a new calcium-carbamide-formaldehyde paste?
Output (English): The calcium-carbamide-formaldehyde paste stimulates bone regeneration and closing of the apex without coloring the hard dental tissues.
