Retrospective analysis of the outcomes of pulpotomies in traumatised permanent anterior teeth

A Partial Pulpotomy in Traumatized Permanent Incisors With Pulp Exposure

A complicated crown fracture in a permanent incisor is one of the most difficult traumatic dental injuries to deal with. Treatment involves multiple visits and invasive intraoperative interventions and this is a very costly procedure. However, progress in vital pulp therapy and adhesive dentistry may allow practitioners to treat these injuries with a conservative method. Correct diagnosis of the pulp is important as it forms the basis for the establishment of an appropriate management strategy. A partial pulpotomy is indicated if the patient has significant pulp exposure or if it is reported after a considerable delay. It has been reported that partial pulpotomies after complicated crown fractures have a 96% success rate. Other studies have reported that partial pulpotomy is a treatment of choice after a complicated traumatic crown fracture, with a very high success record. Traditionally, calcium hydroxide has been applied as a dressing agent. However, research has recently focused on other calcium silicate cements (CSC), such as Biodentine (BD). This study aimed to illustrate the successful management of a vital permanent incisor with complicated crown fractures, which were treated by partial pulpotomy using Biodentine material and evaluated for healing clinically and radiographically. No radiographic signs of failure or clinical symptoms were detected over a one-year period.

A retrospective study of emergent traumatic dental injuries in permanent teeth in Xi'an, China

Traumatic dental injury is one of the common injuries seen in the emergency department. To determine the distribution features of emergency traumatic dental injuries in Xi'an, China, data from the medical records of 623 patients (aged 6-78 years) were evaluated and analyzed according to age, gender, etiology, factors predisposing teeth to injury, and types of teeth traumatized. The patient records of 397 males (63.7%) and 226 females (36.3%), with a 1.8:1 male-to-female ratio, were included. The total number of traumatized teeth was 1475. The highest frequency of dental trauma was found in the 19- to 30-year age group (30.7%). The greatest frequency of dental trauma injuries was in May (13%). Over one-third of patients with traumatic injuries to permanent teeth (n = 218, 35%) injured 2 permanent teeth. The most commonly affected teeth were the maxillary central incisors (59.3%). The most common type of trauma was concussion (20.4%). There was statistically significant difference among the type composition ratio of age groups (P < .05). The most common causes of dental trauma were falls (50.2%). There was statistically significant difference among the etiological composition ratio of age groups (P < .05). Combined injuries were present in 120 teeth in 103 patients (16.5%). The epidemiological characteristics of dental trauma in Xi'an shows that the occurrence of dental trauma is closely related to the age, sex, time, type of injury, and cause of injury. There exists cross-correlation among the epidemiological factors. The most common type of trauma is concussion and the most common cause of dental trauma is fall. High incidence of combined injuries needs extra attention.
