Characteristics of Cracked Teeth with Reversible Pulpitis After Orthodontic Banding-A Prospective Cohort Study.

INTRODUCTION: Cracked teeth with reversible pulpitis can be managed with orthodontic bands in the interim before definitive restorations. The aim of this study was to determine short-term outcomes of these teeth following orthodontic band placement. The time taken for definitive pulp diagnoses after orthodontic band placement and associated prognostic factors was also analyzed. METHODS: One hundred twenty-five patients with a cracked tooth with reversible pulpitis each were recruited. Preoperative data including patient and tooth factors were collected. Cracked teeth were banded and reviewed until symptoms resolved before referral for coronal coverage. Kaplan-Meier and Cox analyses were performed to analyze pulp survival of these teeth. Prognostic factors were investigated using Pearson's chi-square and Student's t-test. RESULTS: One hundred twenty-two cracked teeth were analyzed. One hundred thirteen (92.6%) teeth had the pulpitis resolved within 2 months (median 40.0; interquartile range 28-61). The median time taken for progression to irreversible pulpitis or pulp necrosis for teeth that required root canal treatment was 3 months (median 90.0; interquartile range 68-110). No prognostic factors were associated with the resolution of pulpal symptoms. However, higher preoperative triggered pain scores (P < .05, hazards ratio 1.547) and absence of a distal marginal ridge crack (P < .05, hazards ratio 0.638) were correlated with a longer duration before definitive pulp diagnoses. CONCLUSION: Following orthodontic band placement, a normal pulp diagnosis was achieved in 92.6% of cracked teeth with preoperative reversible pulpitis. Definitive pulp diagnoses could be determined in approximately 2 months. Teeth with higher preoperative triggered pain scores may require a longer review period.

Psycho-social perspectives of nonsurgical versus surgical endodontic interventions in persistent endodontic disease.

INTRODUCTION: Patients' experiences related to dental treatment could influence care-seeking behaviour and engender personal bias. Although endodontic retreatment and apical surgery are procedures often performed to manage previously treated teeth with persistent disease, there is lack of information regarding psycho-social perspectives of patients who undergo these treatments. Our aim was to compare experiences of patients who received these two treatment modalities using a qualitative approach. METHODS: A purposive sample of patients was taken from our previous study utilizing the Oral Health Impact Profile to compare oral health-related quality of life of 150 patients who received retreatment and apical surgery. Patients who reported impact and no impact were invited to participate in focus group discussions (FGDs). Eighteen patients from the retreatment group and 15 patients from the surgical group participated in six FGDs. Thematic analysis was conducted to identify key themes. RESULTS: Four themes emerged: (1) psycho-social disability associated with dental procedures, (2) physical disability associated with dental problems, (3) reliance on dentist's advice for treatment and (4) self-management to preserve treated teeth. Patients undergoing endodontic retreatment reported significant time loss from work and were less informed of alternative treatment options. However, they were pleased with the aesthetics of their teeth, especially if new crowns were made. Patients undergoing surgery experienced anxiety related to loss of control during surgery and apprehension on visualizing the wound post-surgery. They reported more impact on their diet, social interaction and sleep quality and some felt self-conscious due to post-treatment gingival recession. Patients in both groups placed great trust in professional advice and expressed a clear desire to maintain their natural dentition. There was low awareness regarding long-term care and future sequelae of their treated tooth. CONCLUSIONS: Patients reported different psycho-social and physical impacts following endodontic retreatment and apical surgery. Patients undergoing endodontic retreatment were more satisfied with aesthetic outcomes but experienced greater impact related to complexities and length of time taken for treatment. Patients undergoing surgery were better informed of treatment options but experienced greater physical and psycho-social disability during the recovery phase. Clinicians could consider incorporating findings from this study into the patient-dentist discussion.

Factors Influencing Quality of Life after Surgical and Nonsurgical Interventions of Persistent Endodontic Disease.

INTRODUCTION: Nonsurgical endodontic retreatment and apical surgery are predictable procedures for the management of endodontically treated teeth with persistent disease. However, there is no information available that compares these treatment modalities based on patients' oral health-related quality of life (OHRQOL). The aims of this study were to compare the OHRQOL of patients who received nonsurgical endodontic retreatment versus those who received apical surgery and to identify correlations between OHRQOL, clinician-assessed healing outcome, and other factors. METHODS: Patients who received treatment at 2 dental hospitals with a recall period of 6-24 months were invited to participate. They underwent follow-up examination and were surveyed with the Oral Health Impact Profile (OHIP-14). Healing outcomes were determined by clinical and radiographic evaluation. Potential influencing factors for OHIP-14 scores were investigated. RESULTS: One hundred fifty patients (75 patients from each group) participated in the study. There were no differences in OHIP-14 scores between both groups at the follow-up. The overall adverse impact on OHRQOL was low, with patients experiencing greater impact in the domains of "physical pain" and "psychological discomfort." Women and patients who had preoperative pain reported a greater impact. There was an overall high healed and healing rate for both groups. No correlation was found between OHIP-14 scores and healing outcome. CONCLUSIONS: Patients who received nonsurgical endodontic retreatment and apical surgery reported comparable OHRQOL, with women and patients with preoperative pain reporting greater impact. Both treatments are viable options for the management of persistent endodontic disease based on clinician- and patient-reported outcome assessments.
