Based on a 2-year follow-up evaluation, the class I ART restorations seemed to have a high success rate, indicating the appropriateness of the ART approach in primary teeth.

Seventy primary molar teeth, carious exposed, symptom free, without any sign of root resorption in children aged from 3 to 6 years (main age 4.3yr) were treated with conventional pulpotomy procedures. Ferric sulfate 15.5% solution (applied for 15 second for 35 teeth) and formocresol solution (five minute procedure of Buckley's formula for next 35 teeth) have been used as pulpotomy agents. In both groups, pulp stumps were covered with zinc-oxide eugenol paste. Permanent restorations were stainless steel crowns. Clinical check up was every three-months and radiographic follow-up time was six and twenty months after treatment. Our results within this period revealed 100% clinical success rate in both groups. Radiographic success rate was in both groups 97.2%, while in 2.8% cases has shown internal root resorption. On the basis of these results, we can recommend ferric sulfate as a pulpotomy agent in primary teeth in substitution for formocresol at the moment.

Ninety-six patients, fifty-eight healthy patients and thirty-eight special needs patients, ranging in age from 3 to 31yr (average age 6.9yr) had received dental treatments under general anesthesia (GA) at Amiri Hospital. The mean number of dental procedures per child was 13.6 (SD±5.4) with a mean number of 15.6 procedures for healthy patients and 10.5 special needs patients. There was a statistically significantly higher number of dental procedures for healthy patients than for special needs patients (p<0.001). The number of pulpotomies and stainless steel crowns placed for healthy patients was significantly higher (3.5) than for special needs patients (1.3) with (p<0.001) The average number of extractions was similar for the two groups of patients, 2.8 for normal and 2.2 for handicapped. On the basis of these results, it was concluded that dental treatment under GA in hospital environment is beneficial for certain group of patients, such as very young children and those with special needs. Underlying medical conditions influenced the treatment provided.

The paper presents a discussion on etiology and treatment of maxillary central incisors impactions. Different treatment approaches which advocate teamwork approach, and importance of early diagnosis of such conditions is discussed.
