SELECTION OF OBTURATIONS MATERIALS IN PULPECTOMY TREATMENT OF DECIDUOUS TEETH

Introduction: Pulpectomy is the procedure of taking the entire pulp tissue from all the roots and corona of a tooth. There are several materials for obturation / root canal fillers in deciduous teeth, namely zinc oxide eugenol (ZOE), calcium hydroxide and iodoform paste a mixture of calcium hydroxide. A 6 year old boy patient came to RSGM with his parents seeking for treatment a tooth with a large cavity in the upper left posterior region and had been pain before. Intraoral examination revealed deep caries in the occlusal tooth 65 which reaching the pulp, percussion (-), palpation (-), mobility (-), vitality (-). Radiographic examination of tooth 65 showed a radiolucent image that had reached the pulp and the root canals had not yet undergone resorption. The diagnosis of this case was pulp necrosis at tooth 65. Case management: The treatment plan to be carried out was non-vital pulpectomy on tooth 65 and used technique non-vital pulpectomy because the tooth had already necrosis. Discussion: The filler used is ZOE. The reason for choosing this material was because it was indications for the use of ZOE material for teeth with necrosis. Conclussion: ZOE has anti-inflammatory and analgesic properties that can reduce pain

ABSTRACT Aim The purpose of this study is to compare the efficacy of calcium hydroxide and zinc oxide eugenol as a root canal filling material in primary teeth using endodontic pressure syringe system. Materials and methods A total of 40 primary mandibular molars were selected and divided into two groups-group I (calcium hydroxide was used as root canal filling material) and group II (zinc oxide eugenol used as canal filling material). Clinical review was undertaken at 1, 3, 6 and 9 months interval for evaluating pain, tenderness, mobility and any other sign of pathology. Radiographic examination was done at interval of 3, 6 and 9 months for the evaluation of any change in the radiolucency around the apices and inter-radicular space. Resorption of root and filling material was also assessed. Results Reduction in the clinical symptoms were noted in both groups (p < 0.01). All the 20 cases in group I demonstrated a decrease in size of radiolucency. However in group II, an increase in radiolucency was observed in 2 teeth at 3 months radiographic examination. Further no decrease in the size of radiolucency was noticed at subsequent follow-up visits. Complete resorption of overfilled material was observed at the 3 months radiographic examination for group I whereas partial resorption of overfilled material was seen at 6 months radiographic examination for group II. Conclusion The findings of the present study indicate that calcium hydroxide could be used exclusively or as an alternative to zinc oxide eugenol as a root canal filling material for the primary teeth.

Abstract Objective The aim of this study was to evaluate the viability of stem cells from exfoliated and deciduous teeth (SHED) on dentin surface treated with triple antibiotic paste or calcium hydroxide. Materials and Methods Nine single-rooted extracted premolars were prepared appropriately and divided into three groups. In group A, the root canals were left empty, a triple antibiotic paste was placed in the root canals of group B, and calcium hydroxide was placed in the root canals of group C. After 1 week, the intracanal medicaments were removed, and stem cells were seeded on the treated surface of the specimens for 1 more week. The cells were stained and then observed under confocal microscope over the entire surface of each test material. Counting of the cells was made by Image J (3D) software, as well as manually. Statistical Analysis To investigate any statistically significant differences between the experimental groups, statistical tests including Kruskal–Wallis and Mann–Whitney U-test were performed. Significance level was set to P < 0.05, and all analyses were performed with SPSS IBM program, v. 21. Results Groups B and C showed statistically significantly higher number of cells compared to Group A, whereas cells developed in a substrate of calcium hydroxide residues appeared in majority with distinct cores and widened unlike other groups. Conclusions The effect of calcium hydroxide manifested better results regarding the number of stems cells on root canal surfaces.

The aim of this systematic review was to determine whether there is a root canal filling for deciduous teeth equally or more effective than zinc oxide-eugenol cement (ZOE). Six clinical trials selected for inclusion were independently reviewed by two researchers. Only two showed statistically significant different success rates between the test and the control groups. One found that an iodoform paste with calcium hydroxide () performed better than ZOE, and the other found that ZOE performed similarly to . The other four studies compared ZOE with an iodoform paste (IP), a calcium hydroxide cement , or . In these trials, the success rates in the ZOE groups were slightly lower than in the other groups. There seems to be no convincing evidence to support the superiority of any material over ZOE, and both ZOE and appear to be suitable as root canal fillings for deciduous teeth.

Objective: The present study aimed to evaluate and compare six different materials commonly used for filling the root canals of primary teeth for antimicrobial efficacy against some of the microorganisms commonly found in infected root canals. Study design: In this experimental in vitro study six root canal filling materials were tested for antimicrobial efficacy against eight microbial strains using the agar diffusion method. Results: Zinc oxide eugenol paste exhibited the strongest antimicrobial potential followed by Endoflas™, zinc oxide-calcium hydroxide-sodium fluoride mixture, zinc oxide-calcium hydroxide mixture and calcium hydroxide paste (Apexcal™). The addition of sodium fluoride to the zinc oxide-calcium hydroxide mixture enhanced the antimicrobial efficacy. Metapex™ demonstrated minimal inhibition and Vaseline™ was non-inhibitory. Conclusions: All the test filling materials demonstrated varying antimicrobial activity against the microorganisms tested. Zinc oxide eugenol paste and materials containing zinc oxide were found to be more effective against the microorganisms compared to materials without zinc oxide.

Composite Resin Restoration

External Root Resorption (ERR) is a pathological condition that can lead to tooth loss if not diagnosed and treated correctly. Calcium Hydroxide Ca(OH)2 is an intracanal medicament, which is used in cases of teeth with pulp necrosis, peri-radicular lesions and ERR. This paper describes the endodontic management of a tooth with severe ERR using injected non-setting Ca(OH)2 paste. A 28-year-old patient was referred for endodontic evaluation of tooth 47, which presented an extensive composite resin restoration and was negative to cold test. Panoramic and periapical radiographs revealed the presence of a filled pulp chamber, calcified root canals, ERR on the mesial and distal roots, and apical periodontitis in the mesial and distal roots. The diagnosis of asymptomatic apical periodontitis and severe ERR was established, and conventional root canal treatment combined with non-setting Ca(OH)2dressing was chosen. After five months, no more discharge from the root canal was observed, and a decrease in the size of the periapical lesion and arrest of ERR was detected. The root canal was filled, and the patient was referred for restoration. At the 6-months follow-up, radiographic examination evidenced periapical repair and containment of the ERR process. Chemomechanical root preparation in association with a non-setting Ca(OH)2 dressing protocol allows positive outcomes during the management of severe ERR associated with pulp necrosis and periapical inflammation.

Clinical Signs And Symptoms

Root canal and furcal perforations are causes of endodontic therapy failure and different materials that stimulate tissue mineralization have been proposed for perforation treatment. In the first case, a patient presented tooth 46 with unsatisfactory endodontic treatment and a periapical radiographic lesion. A radiolucent area compatible with a perforating internal resorption cavity was found in the mesial root. The granulation tissue was removed, and root canals were prepared. The intracanal medication was composed of calcium hydroxide and the perforation cavity was filled with Portland cement. The 11-year followup showed radiographic repair of the tissue adjacent to the perforation and absence of clinical signs and symptoms or periapical lesion. In the second case, a patient presented with edema on the buccal surface of tooth 46. The examination showed a radiolucent area in the furcation region compatible with an iatrogenic perforation cavity. The mesial root canals were calcified, and only the distal root canal was prepared. The cavity was filled with a calcium hydroxide-based paste and the distal root canal was obturated. In sequence, the perforation cavity was filled with Portland cement. The 9-year followup showed the tooth in masticatory function with radiographic and clinical aspects compatible with normality.

The purpose was to assess the elimination of Enterococcus faecalis in vitro in human mandibular premolars after chemomechanical preparation with or without the use of a calcium hydroxide dressing. After 60 days of contamination with E. faecalis, the root canals were prepared using the Crown-Down technique combined with 2% chlorhexidine gel irrigation. Then, the specimens were divided into two experimental groups, treated in a single visit or in multiple visits, and two control groups. The multiple-visit group received a dressing with calcium hydroxide for 14 days (CalenTM) and the single-visit group did not receive any medication. In the two control groups, the canals were filled with BHI after chemomechanical preparation with 2% chlorhexidine gel or distilled water. Microbial samples were taken from the root canals for colony forming unit count for each phase of the treatment using sterile paper points inside the root canal lumen. Data were ranked and analyzed by the Kruskal-Wallis statistical test. The residual microbial colonies were then assessed. The results showed that chemomechanical preparation using 2% chlorhexidine gel with no intra-canal dressing reduced by 100% the E. faecalis contamination of the root canal lumen. The calcium-hydroxide group that received the 14-day intra-canal dressing allowed a small number of bacteria to grow between visits, but without statistical differences between groups.

AIM: The aim of this study was to evaluate the efficacy of different lengths of time of passive ultrasonic irrigation (PUI) in removing calcium hydroxide (CH) paste from root canal, using scanning electron microscopy and energy dispersive spectrometry (SEM/EDS). MATERIAL AND METHODS: Fifty-four human premolars were used. After coronal access, a size #15 K-file was used to obtain apical patency. Root canal preparation was performed using WaveOne 40.08 instruments. CH paste was placed into the root canal. Specimens were stored in a humid environment, and after seven days, they were divided into five groups (n=12) according to the irrigation protocols: Manual– a size #40 K-file; PUI/1– 1 min; PUI/2– 2 min; PUI/3– 3 min; and Control– without CH paste. An elementary chemical microanalysis (SEM/EDS) was performed to quantify the presence of calcium on the dentinal walls. RESULTS: The percentage of calcium was higher in all experimental groups when compared to the control group (P < 0.05); but no differences among them were found (P > 0.05). CONCLUSION: The amount of calcium hydroxide paste on the dentinal walls was not dependent on length of time of ultrasonic activation. SEM/EDS analysis seems to be a reliable method to assess CH paste removal from the root canals.

Background: The success of the endodontic treatment is largely dependent on the sealing achieved by root canal obturation. The application of sealer fills imperfections and increases adaptation of the root filling to the canal walls. Aim: To evaluate the sealability of experimental nanosealers (nano calcium hydroxide and nano bioactive glass) and to compare it with the commercial zinc oxide eugenol sealer using a dye penetration method. Materials and Methods: Sixty single-rooted mandibular premolars were selected. The tooth crowns were removed so as to obtain standardized 15-mm-long root specimens. The root canal was instrumented with Protaper Ni-Ti rotary file and the final file size was up to # F4/.06 (in vitro study). They were then randomly allocated into 3 groups of 20 specimens each (n=20) according to the sealer used for obturation, and all samples were filled with single cone gutta-percha (#40/06) and one of the tested sealers. All teeth were coated with nail polish and then suspended in 2% methylene blue dye for 7 days. Stereo-microscope (x10) was used to evaluate the sealability of newly introduced nanosealers. The data were statistically analyzed by ANOVA test followed by post hoc analysis (P < 0.05). Results: Significant improvement shown by the presented study suggests that nano calcium hydroxide sealer showed significantly less dye leakage than nano bioactive glass sealer and zinc oxide eugenol sealer. Conclusion: The results of this study showed that the synthesized nano-powder sealers are suitable for use in root canal therapy to prevent leakage. The root canal can be sealed better by using smaller nano-powder particle sizes. In addition, the two groups exhibited significant differences in leakage in comparison with commonly used ZOE sealer.

ABSTRACT Aim To evaluate the interference of the intracanal medication Calen® (SSWhite, São Paulo, Brazil) on the filling of simulated lateral canals. Materials and methods Twenty human anterior teeth were used. Before the endodontic filling procedures the access of cavity was made, and after this root canals were made in all the teeth to simulate the presence of lateral canals. After preparation, the teeth were randomly divided into two groups (n=10). In group I, the root canal system was filled directly after chemicalmechanical preparation; in group II, endodontic treatment was performed in multiple sessions, and after preparation the calcium hydroxide-based intracanal medication Calen® was inserted. After the period of 7 days, the root canals were vigorously irrigated and then they were filled. Next, the teeth were radiographed to verify the quality of the filling. Results The results demonstrated that the teeth treated in a single session, without calcium hydroxide medication, presented 47 canals out of 60 with radiographic evidence of filling, whereas the teeth in which intracanal medication was used, only 07 presented a radiographic image compatible with filling (p < 0.05). Conclusion The use of the calcium hydroxide-based medication Calen made it difficult to obtain a hermetic filling of the root canal system. Clinical significance The clinical significance of this work basing on the fact that once the dentist knowing that property obliteration of calcium hydroxide can be taken care when they are used in the presence of lateral canals.
