Abstract

Background. Multi-appointment apexification using calcium hydroxide (CH) is the best known effective method of treatment. However, shortening the therapeutic procedure is desired.
Objectives. The essessment of apexification efficacy when using a mixture of CH-based material and hydroxyapatite (HA).
Material and Methods. Treatment based on the apexification technique was conducted in 12 incisors and 1 molar of 13 patients. In the research the mixture of CH-based material and HA powder was used. The mixture was cyclically exchanged and the presence of mineral barrier was clinically verified.
Results. Successful apical barrier formation was noted in 100% cases qualified for research. The average treatment time reached 6.77 months.
Conclusion. A mixture of CH and HA effectively stimulates the apexification process. However, further research is required to find if an admixture of hydroxyapatite accelerates the periapical mesenchymal cells’ organisation in relation to CH based-apexification.

Streszczenie

Wprowadzenie. Wieloseansowa apeksyfikacja z zastosowaniem wodorotlenku wapnia jest najlepiej poznaną skuteczną metodą leczenia. Dokłada się jednak starań w celu skrócenia długoterminowego postępowania w leczeniu zębów z nieuformowanymi wierzchołkami korzeni.
Cel pracy. Ocena procesu apeksyfikacji po zastosowaniu mieszaniny wodorotlenku wapnia i hydroksyapatytu.
Materiał i metody. Apeksyfikację przeprowadzono u 13 pacjentów w 12 zębach siecznych i 1 zębie trzonowym. W badaniach zastosowano mieszaninę wodorotlenku wapnia i hydroksyapatytu, którą cyklicznie wymieniano i jednocześnie przeprowadzano kliniczną kontrolę pod kątem obecności bariery wierzchołkowej.
Wyniki. Pomyślną apeksyfikację zanotowano w 100% przypadków zakwalifikowanych do leczenia. Średni czas leczenia wyniósł 6,77 miesiąca.
Wnioski. Mieszanina wodorotlenku wapnia i hydroksyapatytu jest skutecznym materiałem odontotropowym w procesie apeksyfikacji. Potrzebne są jednak wnikliwe badania, czy domieszka hydroksyapatytu przyspiesza transformację mezenchymy okołowierzchołkowej w stosunku do procesu zachodzącego z udziałem samego wodorotlenku wapnia.
