Orthodontic movement of a horizontally fractured tooth: a case report

Dental Traumatology, Jun 1, 2005

Traumatic injuries in teeth and their supporting structures occur most commonly in young patients... more Traumatic injuries in teeth and their supporting structures occur most commonly in young patients, and vary in severity from enamel fractures to avulsions (1). Root fractures, combined injuries of pulp, dentin, cementum and periodontal ligament, are less frequent injuries comprising 0.5-7% of all trauma cases (1-3). Horizontal root fractures are more frequently observed in the maxillary anterior region and in the 11-20 year age group male patients (1). They occur in fully erupted teeth with complete root formation (4, 5) and are frequently seen in the middle third of the root followed by apical and coronal third fractures (5, 6). The prognosis of the root fractures in the coronal third is poorer than the root fracture in the middle or apical third. The clinical presentation of a horizontal root fractures may vary from an extruded or displaced crown to a clinically normal tooth (5). Generally, fractured roots are diagnosed within a short time after the injury but occasionally they are identified at subsequent routine dental appointments (7). The reduction and alignment of the displaced segments and stabilization and relief of the occlusion may be applied in horizontal root fractures if it is located below the alveolar crest and there is no oral communication (6, 8, 9). Then the tooth should be monitored for pulpal vitality (9). Fractures that do not heal after the initial treatment may need additional treatment consisting endodontic, periodontal and orthodontic procedures (5). However, healing of root fractures without treatment is also presented in many reports (6-8, 10-12). The sequelae of root fractures may be divided into four categories; (i) healing with calcified tissue, (ii) healing with connective tissue, (iii) healing with bone tissue, and (iv) granulation tissue without healing (8). Different types of healing may depend on the proximity, repositioning and the fixation of the fragments and on the absence of infection (8). This paper reports a case of horizontal root fractured tooth that was healed satisfactory without treatment and moved orthodontically after prolonged time from trauma. Case A 15-year-old man referred to the endodontic clinic at the School of Dentistry, Selçuk University, Turkey in 1996. He had recurrent pain and swelling on the maxillary anterior region. The patient's medical history was unremarkable. Clinical examination revealed that there were hyperemia and edema in the apical region of the maxillary right incisor tooth. It

IL‐1β and TNF‐α levels were determined by enzyme‐linked immunosorbent assays. The samples were divided into two groups according to the presence or absence of clinical signs including swelling and/or fistula, pain on palpation and/or percussion, and pus discharge from canals. Periapical exudate samples were divided into two groups according to size of periapical radiolucent area.Results The mean concentration of IL‐1β (72.79 ng mL−1) in periapical exudates was approximately 12‐fold higher than TNF‐α (6.17 ng mL−1). There was no significant correlation between these cytokines (P &gt; 0.05). IL‐1β levels in canals with larger radiolucent areas (long axis ≥1 cm) were significantly higher than those with small areas (P &lt; 0.05). There was a tendency toward higher levels of IL‐1β in groups with clinical signs, but the differences were not significant (P &gt; 0.05).Conclusions Periapical exudate levels of both cytokines failed to reflect periapical disease state.

Sixty-five extracted human maxillary central incisors with intact crowns were used. Following obturation with gutta-percha and a root canal sealer using a lateral condensation technique, the coronal aspects of the root canal fillings were covered with a 1-mm thick protective base placed to a level 1 mm apical to the labial cemento-enamel junction (CEJ). The teeth were than stained artificially with fresh blood over a period of 18 days. One or other of the bleaching materials (group 1: SP monohydrate + water, group 2: SP trihydrate + water, group 3: SP tetrahydrate + water, group 4: SP monohydrate + hydrogen peroxide (HP), group 5: SP trihydrate + HP, group 6: SP tetrahydrate + HP) were placed in the pulp chamber of the discoloured teeth and sealed with Cavit for 21 days. They were replaced with fresh preparations after 3, 7 and 14 days. The shades of the tooth crowns were evaluated at baseline and at 7, 14 and 21 days. Comparison of tooth shades was completed at each interval and analysed statistically using the chi-squared test. There was no statistically significant difference between the groups at 7, 14, 21 days. Period of bleaching significantly affected the outcome (P &amp;amp;lt; 0.01). No colour changes were noted in the control teeth. The data obtained from this study demonstrate that sodium perborate can be used mixed with water rather than with hydrogen peroxide for bleaching discoloured teeth.

Replantation after extended dry storage of avulsed permanent incisors: report of a case

Dental Traumatology, 2007

Oral trauma resulting in tooth avulsion creates special problems for the patient and the dentist.... more Oral trauma resulting in tooth avulsion creates special problems for the patient and the dentist. Avulsion accounts for 0.5-16% of traumatic injuries in the permanent dentition (1). Avulsion of permanent teeth can occur at any age, but is most common in young permanent dentitions. This is because the root is still not completely formed and the periodontium bone is very resilient (2). Normally, treatment of avulsed teeth is by replantation of the avulsed tooth into its own socket. As an emergency procedure it is advisable to replace a traumatically avulsed tooth, but unfortunately it has a rather low long-term success ratio when compared with routine endodontic therapy. One cause for this poor rate is the lack of recognition that avulsed teeth are presented in the dental office under different conditions that require different treatments (3). The replantation of an avulsed tooth should depend on the specific clinical conditions associated with that particular avulsed tooth. These clinical factors include the physiologic status of the PDL, the stage of root development and the length

Procedure durations were recorded. Patients answered a questionnaire on daily analgesic requirements and about clinical symptoms (pain intensity, chewing sensitivity and thermal sensitivity) after the anaesthetic effect had disappeared (Day 0) and on Days 1, 3 and 7 post‐treatment.ResultsThe total pulpectomy group was associated with the longest procedures (median, 24 min), followed by the partial pulpectomy and pulpotomy groups (P < 0.001 for all). In all three groups, pain intensity, thermal sensitivity and chewing sensitivity decreased significantly from the preoperative time‐point to Day 7 (P < 0.001 for all)....

After the filling procedure, apical leakage quantity was measured at 4 weeks using a fluid filtration method. One root from each group was processed for scanning electron microscopy and energy dispersive X-ray spectroscopy analyses. Both EDTA/MTA and laser irradiation/MTA combinations showed significantly lower microleakage than EDTA/iRoot BP and laser irradiation/iRoot BP combinations (p<0.05). Between groups of the same filling material, there were no significant differences among specimens treated with EDTA or laser (p>0.05). Both MTA and iRoot-BP demonstrated tag-like structures within the dentinal tubules when used in conjunction with EDTA.

Patients answered a questionnaire on daily analgesic requirements and about clinical symptoms (pain intensity, chewing sensitivity and thermal sensitivity) after the anaesthetic effect had disappeared (Day 0) and on Days 1, 3 and 7 post‐treatment.ResultsThe total pulpectomy group was associated with the longest procedures (median, 24 min), followed by the partial pulpectomy and pulpotomy groups (P < 0.001 for all). In all three groups, pain intensity, thermal sensitivity and chewing sensitivity decreased significantly from the preoperative time‐point to Day 7 (P < 0.001 for all)....

After the filling procedure, apical leakage quantity was measured at 4 weeks using a fluid filtration method. One root from each group was processed for scanning electron microscopy and energy dispersive X-ray spectroscopy analyses. Both EDTA/MTA and laser irradiation/MTA combinations showed significantly lower microleakage than EDTA/iRoot BP and laser irradiation/iRoot BP combinations (p<0.05). Between groups of the same filling material, there were no significant differences among specimens treated with EDTA or laser (p>0.05). Both MTA and iRoot-BP demonstrated tag-like structures within the dentinal tubules when used in conjunction with EDTA.

Subjects and Method: The teeth examined were 202 first molars (83 men, 118 women; age range, 18-68 years), 129 second molars (60 men, 69 women; age range, 18-77 years), and 15 third molars (7 men, 8 women; age range, 30-61 years) treated over a 4-yr period of time by 1 endodontist. The results were recorded on a computer program and all the proportions were analyzed by using chi-square (likelihood ratio) test and two proportions z-test. All levels of significance were set at p<0.05. Results: The prevalence of MB2s decreased from first to third molars (70.2%, 31.7%, 14.3%, respectively); type II (2 treatable canals that joined) and type III (2 treatable canals with 2 separate apical foramina) canal configurations were th...
