ABSTRACT

INTRODUCTION: The aim of this study was to compare postoperative pain and success rate following pulpotomy and root canal treatment. METHODOLOGY: Fifty-four permanent teeth with carious exposures were randomly divided equally into 2 groups. Mineral trioxide aggregate pulpotomy was performed in the experimental group and root canal treatment was performed in the control group, using standardized protocols. The treated teeth were restored with base of glass-ionomer cement followed by composite restoration. Pain was recorded every 24 hours for 7 days after intervention. Clinical and radiographic evaluations were done every 3 months for 18 months. The data collected were statistically analyzed. RESULTS: At the end of follow-up, overall success rate was 85% in the pulpotomy group and 87.5% in the root canal treatment group (P > .05). Significant difference in pain incidence and pain reduction was found between the 2 groups (P < .05), with lower scores reported in the pulpotomy group. CONCLUSION: Pulpotomy can be an alternative treatment for management of symptomatic permanent teeth with deep caries lesions.

ABSTRACT

A 10-year-old DSH cat was referred for a dental evaluation and extraction procedure. Subsequently, the animal developed an acute onset of ocular discharge. Ophthalmologic examination revealed presence of unilateral ocular mucoid discharge leading to a diagnosis of epiphora secondary to nasolacrimal duct obstruction. Dacryocystorhinography was performed and confirmed the presence of a nasolacrimal duct obstruction, presumably acquired after an invasive dental procedure. Additionally, a vinyl cast in situ study of the nasolacrymal apparatus was performed to demonstrate the route of the nasolacrimal duct in the cat and its relationship to oral dental structures. This report documents an unusual case in which excessive inflammation/edema following tooth extraction caused acute epiphora secondary to extraluminal compression of the distal nasolacrimal duct.

ABSTRACT

BACKGROUND: Traumatic injuries of permanent teeth with incomplete root formation are frequent during childhood. Adequate therapy is important for the further destiny of teeth with damaged pulp. OBJECTIVES: To evaluate the effect of pulpotomy and high pulpotomy on the pulp and on root development, and the effect of platelet rich plasma (PRP) with hydroxyapatite (HAP) as a carrier and hydroxyapatite alone on apexogenesis. MATERIAL AND METHODS: The study included eight monkeys (Cercopithecus aethiops) in which high pulpotomies were performed on the mandibular lateral incisors and canines, and pulpotomies were performed on the mandibular central incisors and premolars. The materials used in the study were commercial HAP (Apatec®, Stomygen) and PRP (prepared at the Torlak Institute of Immunology and Virology, Belgrade, Serbia.). Histological and radiological evaluations were done six months after the treatment. RESULTS: Considering the differences between HAP+PRP treated teeth in the pulpotomy group and teeth in the high pulpotomy group, two times more root growth retardation was observed in the high pulpotomy group. In the high pulpotomy group, root growth retardation was less common in HAP+PRP treated teeth (42.9%) than in HAP treated teeth (50%). In the pulpotomy group, retardation of root development was also less common in HAP+PRP treated teeth (25%) compared to HAP treated teeth (50%). There were differences between the pulpotomy and high pulpotomy groups, but without statistical significance. CONCLUSIONS: The application of endogenous growth factors in conjunction with the preservation of dental pulp vitality can result in a good outcome for pulp therapy of injured teeth, which means successfully completed apexogenesis.

ABSTRACT

PURPOSE: The aim of this study was to compare the effect of white mineral trioxide aggregate (MTA) to that of formocresol (FC) as pulp dressing agents in pulpotomised primary molars. METHODS: In this clinical trial study, 60 lower second primary molars of 46 children were treated by a conventional pulpotomy technique. The teeth were randomly assigned to the MTA (experimental) and FC (control) groups by random numbered table. Following removal of the coronal pulp and haemostasis, the pulp stumps were covered with an MTA paste in the experimental group. In the control group, FC was placed with a cotton pellet over the pulp stumps. The teeth of both groups were restored with stainless steel crowns. Children arrived for clinical and radiographic follow-up evaluation after 6, 12 and 24 months. RESULTS: The treated teeth in FC group (n = 18) were clinically and radiographically successful after 24 months. The radiographic follow-up evaluation revealed one failure (furcation involvement) in 18 molars treated with MTA after 24 months. The treated teeth in MTA group were clinically successful 24 months postoperatively. Pulp canal obliteration was observed in one of the teeth treated with MTA and four of the teeth treated with FC. CONCLUSION: MTA could be used as a safe medicament for pulpotomy in cariously exposed primary molars and could be a substitute for FC.

ABSTRACT

BACKGROUND/AIMS: The aim of this study was to analyse the residual periodontal attachment in teeth extracted by East German dentists in order to determine a possible 'forceps level'. METHODS: Out of about 8000 extracted teeth collected from a dental waste disposal company, 500 teeth were randomly selected. After exclusion of wisdom teeth and premolars extracted for orthodontic reasons (intact teeth with attachment > 90%), coronal and root caries, fillings, pulp exposure and incomplete root fillings (based on X-rays) were registered. The periodontal ligament was stained with 1% Fuchsin Red and measured with a light microscope. RESULTS: For intact teeth (DF = 0, periodontal disease definition I), the mean periodontal attachment (50.5% +/- 16.0) was significantly lower than for teeth with carious defects or fillings (64.7% +/- 18.8. unpaired t-test: p < 0. 00 1). There was a marked increase in frequency of extractions in intact teeth below 70% periodontal attachment and 37% were extracted at attachment levels between 50 and 69%. Teeth with pulpal involvement showed significantly different frequency distributions and mean attachment values (77.9% +/- 17.8) than the remaining teeth (periodontal disease definition II; 55,2% +/- 15.5). CONCLUSIONS: A considerable number of teeth with no or minor coronal destruction were extracted at an attachment level of 50-70%, regardless of the tooth type. The threshold for 'periodontal' extractions seem to be too low and undifferentiated, which calls for an improvement in knowledge of periodontal diagnosis and treatment.

ABSTRACT

A clinical protocol is described for the treatment of intentional and unavoidable exposed pulps during crown preparation. The protocol includes a definitive cavity preparation to create space in the exposed dentin for an adhesive pulp barrier; procedures to develop the highly desirable hybrid zone to prevent microleakage; the use of a specific resinous material that serves as a long-term pulp barrier with a relatively neutral and biocompatible impact on the pulp; and the use of precise bipolar electrocoagulation to provide durable hemostasis for restoration of the pulp wall and a relatively clot-free surgical wound to facilitate healing. The protocol involves the application of gentle surgical and restorative procedures to support the inherent healing process to restore the health of the pulp. The patient presented was part of a larger investigation and was selected in an attempt to identify a fixed prosthodontic application of the proposed pulp therapy protocol.

ABSTRACT

OBJECTIVE: To study the effects of Nd: YAG laser irradiation on the canine tooth pulps. METHODS: The crown pulp of dog was exposed and excised by ND: YAG laser irradiation. Histopathological examination was used to check changes of the tissues in root canal and periodontium. RESULTS: The pulp of the crown could be successfully excised by Nd: YAG laser without harmful changes in either root canal or periodontal tissues. CONCLUSION: This study may provide an experimental basis for the clinical possibility of crown pulp excision by using Nd: YAG laser irradiation.

ABSTRACT

The aim of this study was to compare the effect of ferric sulfate (FS) to that of dilute formocresol (DFC) as pulp dressing agents in pulpotomized primary molars. Ninety-six primary molars in 72 children were treated by a conventional pulpotomy technique. Fifty-eight teeth were treated by a FS solution for 15 sec, rinsed, and covered by zinc oxide-eugenol paste (ZOE). In another 38 teeth, a cotton pellet moistened with 20% DFC was placed for 5 min, removed, and the pulp stumps were covered by ZOE paste. The teeth of both groups were sealed by a second layer of intermediate restorative material (IRM) and restored with a stainless steel crown. This is a report of the clinical and radiographic examination of 55 teeth dressed with FS and 37 teeth fixed with DFC, that have been treated 6 to 34 months previously (mean 20.5 months). Four teeth were excluded from the study due to failure of the patient to present for recall. Success rates of 92.7% for the FS, and of 83.8% for the DFC were not significantly different. Four teeth (7.2%) of the FS group and two (5.4%) of the DFC group presented internal resorption. Inter-radicular radiolucencies were observed in two teeth of the FS group and three teeth of the DFC group. The latter also presented periapical lesions. Success rates of both groups were similar to those of previous studies utilizing the traditional Buckley's formocresol.

ABSTRACT

BACKGROUND AND OBJECTIVE: Successful non-devitalizing treatment of localized pulpal lesions in mature teeth is not ensured using conventional endodontic techniques. The objective of this study was to evaluate CO2 laser surgical treatment of pulpal exposures in canine patients. STUDY DESIGN/MATERIALS AND METHODS: 17 permanent teeth with pulpal exposures of < or = 48 h duration received localized laser pulp surgery. Laser Parameters: pulse duration: 0.01 s, pulse interval: 1.0 s, spot size: 0.004 cm2, fluence: 276 J/cm2. Exposures were dressed with CaOH and Glass ionomer. Clinical and radiographic evaluations were performed by one blinded clinician 24 and 52 weeks after treatment. RESULTS: 15/17 laser-treated teeth assessed over > or = 1 year post-treatment remained clinically and radiographically healthy. CONCLUSION: These results demonstrate the feasibility of using the CO2 laser for localized pulp surgery. Further studies must optimize laser parameters and identify the range of clinical pathologies which can be treated using this modality.

ABSTRACT

The material comprised 37 young posterior teeth with deep carious lesions and exposed pulps, treated with partial pulpotomy and dressed with calcium hydroxide. The teeth were divided into two groups. Group 1 consisted of 31 teeth with no clinical or radiographic symptoms before treatment, Group 2 of 6 teeth with temporary pain, widened periodontal space periapically and/or productive osteitis, i.e. increased density of the surrounding alveolar bone. After an observation time of 24 to 140 months (mean = 56 months), healing had occurred in 29 of 31 teeth in Group 1 (93.5%) and in 4 of 6 teeth in Group 2. It was concluded that the present, as well as previously reported results indicate that partial pulpotomy may be an adequate treatment for young permanent molars with a carious exposure, although more studies are needed before the treatment can be recommended for routine clinical use.

ABSTRACT

The purpose of this study was to assess the long-term success of partial pulpotomy in traumatized permanent incisors. Seven years before this examination, 63 teeth that had been treated by partial pulpotomy six months to four years earlier were examined. At that stage, four teeth had pulp necrosis. The remaining 59 cases were recalled for re-examination. Of these, 40 were available for assessment 7.5 to 11 years after the partial pulpotomy treatment. Thirty-five of these teeth were successful, while the remaining five had root canal fillings, and three of them were restored by post and crowns. Of these, two were root treated in consequence of new trauma, and the other two for esthetic purposes. The fifth tooth has probably been root treated for similar reasons, as the patient reported not having had any pain or problem with the tooth. The high frequency of long-term success justifies recommending partial pulpotomy as the treatment of choice for traumatic pulp exposures in crown-fractured permanent incisors.
