Main Article Content
Abstract
Background: Vital pulp therapy is a restorative dental procedure aimed at preserving the vitality of the tooth and maintaining the normal condition of the pulp tissue, allowing continued root development. The treatment promotes healing of the injured pulp tissue.
Objective: To present a method of vital pulp therapy involving partial removal of the coronal pulp tissue, with an alternative treatment option being complete removal of the coronal pulp tissue, and to demonstrate the success of the treatment after a 2-year follow-up period.
Methods: In this 2 cases, two 8-year-old Thai boys sustained trauma from a fall, resulting in fractures of the maxillary central incisors (#11 and #21) and maxillary central incisor #21 with pulp exposure. Radiographic examination revealed that root formation was incomplete, with only two-thirds of the root developed.
Results: The treatment involved removing the inflamed coronal pulp tissue (Partial pulpotomy) and covering it with Mineral Trioxide Aggregate (MTA) (Retro MTATM), followed by restoration with composite resin to prevent microleakage and to restore the normal tooth contour, improving the patient’s confidence.
Conclusions: Follow-up evaluations were conducted at 1 month, 3 months, 6 months, 1 year, and 2 years. The results showed normal root development of both anterior teeth, positive to cold test, increased root length, thickened root dentin and closure of the root apex with no signs of periapical inflammation or infection. The patient was able to maintain normal daily activities without any complications.
