The Influence of Two Etiological Factors of Pulp Diseases on the Success of Regenerative Endodontic Procedures in Immature Human Teeth (A Comparative in-Vivo Study)

Abstract

Endodontic revascularization is a simple procedure, relatively inexpensive and easily performed. In addition to this, the chances of saving the tooth will still be high in case of failure with revascularization, as traditional endodontic lines of treatment will still be available (19). Eventually it is of less significance if the newly regenerated tissue is a true pulp tissue or pulp- like, as long as the immature root continues to develop and grows stronger by the deposition of mineralized tissue in the root canal (2). In our study, 48 patients with immature permanent and necrotic anterior teeth were allocated. These cases were equally divided into 2 groups; Caries Group (Group A) and Trauma Group (Group B). Both groups received calcium hydroxide for 2 weeks as an intracanal medicament in the first visit, then bleeding was induced into the disinfected canals in the second visit, as part of the revascularization procedure. Cases were sealed using white MTA coronal plug and composite. Cases were followed up regularly at 3, 6, 9 and 12 months.

Cases were evaluated both clinically and radiographically. Clinical evaluation included obtaining a pre and postoperative detailed history from both the patients and guardians, regarding the presence or absence of pain, swelling or a sinus tract. Radiographic evaluation included measurements of the change in root thickness, length and apical diameter using standardized radiographs. All data were collected and tabulated for statistical analysis.

Clinically, cases were asymptomatic and in function along the follow-up period. Some cases experienced mild discomfort postoperatively that lasted only for a few days. There was a
