Reattachment of a fractured fragment to the remaining tooth is challenging but one of the best treatment protocol in regards to aesthetics, function as well as patients acceptance. This case report presents a 20 years old male with an oblique complicated crown fracture of maxillary left central incisor tooth. The procedure used to repair the fracture regarding this case included flap surgery with endodontic treatment. The root canal was filled with a root canal sealer and gutta-percha. After root canal obturation, fragments were reattached with duel cure composite resin using a glass fibre post. After 12 months evaluation, clinical and radiographic examinations showed a stable reattachment, good aesthetics and healthy periodontium.
In the present study, a conservative approach for removal of a fractured instrument located at the apical root area of maxillary left central incisor of a 35 years old male was performed and the clinical outcome was evaluated. On clinical examination, localized swelling associated with discharge of pus was seen near to the affected tooth. Furthermore, the tooth was restored with temporary filling and it was severely discolored. On radiographic examination, a radiolucent area around the apex was seen and there was a fractured instrument at the apex of the tooth. Tooth was then treated as nonsurgical endodontic technique and an attempt to remove the fractured instrument was undertaken. The results confirms that fractured instrument was successfully removed by using the File Braiding technique and after 3 months follow up, the tooth was asymptomatic and radiograph shows complete healing of the periapical lesion.DOI: http://dx.doi.org/10.3329/updcj.v2i1.13957 Update Dent.

Bacteremia is common with manipulation of the teeth and periodontal tissues during dental procedures. Majority of dental office visits result in some degree of bacteremia that warrants antibiotic prophylaxis before a dental procedure to reduce the frequency, nature or duration of bacteremia. This study aimed to collect data on prophylactic use of cephradine which is most preferred in dental procedures in Bangladesh. A total 2219 of patients both adult and children above 5 years were enrolled to assess use of antibiotic, its dose and duration for antibiotic prophylaxis during dental procedures. Efficacy of antibiotic prophylaxis in terms of clinical cure, further dose modification and need to change antibiotic was evaluated at day 10 of antibiotic use and in case of root canal therapy at day 30. Any side effect of antibiotic use recorded within 3 days was considered for safety evaluation. This was a non-controlled, multicentre, observational study. 2016 (90.9%) of the patients received cephradine as prophylactic antibiotic with a mean dosage of 500mg (487.48+60.99) and duration of treatment was 3-7 days (5.47+1.03). Some of the dentists also preferred amoxicillin (149, 6.7%) and cephalexin (54, 2.4%) for prophylaxis. The majority of the patients (1657, 82.2%) who had prophylaxis with cephradine had no clinical sign of infection and some of the patients needed to change their initial dose or change of the antibiotic. Overall 1816 (81.8%) patients were found having no clinical sign of infection on antibiotic prophylaxis. Among the patients 239 (10.7%) needed to change the dose of prescribed antibiotic and 55 (2.4%) were required to change their prescribed antibiotic. However, the data on type of infection was not recorded. 109 (4.9%) patients were lost to follow up on Day 10. Prescribed antibiotic prophylaxis was not associated with adverse events in majority (91%) of the patients. Some of the patients reported diarrhea (104, 4.7%), stomach upset (68, 3.1%) and dizziness (31, 1.4%) during antibiotic use. However, those were self-limiting and no dose adjustment, discontinuation of therapy or withdrawal from the study was required. No serious adverse events were reported. Cephradine 500 mg for 5 days course was preferred as prophylactic antibiotic in dental procedures in this study. Majority of the patients had no clinical sign of infection on evaluation at day 10. Cephradine therapy was mostly not associated with adverse events in patients; however, diarrhea, stomach upset and dizziness were reported in some patients that were self-limiting.Bangladesh Journal of Dental Research and Education Vol.5(2) 2015: 49-54
Microorganisms, usually from the dental caries, are the main sources of diseases in dental pulp (root canals) and periapical region. Facultative bacteria and fungi have been identified in therapy resistant persistent endodontic infection. The objectives of this study was to evaluate the antimicrobial efficacy of Mineral Tri Oxide Aggregate (MTA) against therapy resistant endodontic microorganisms. The efficacy of MTA was also compared with that of calcium hydroxide. Six standard bacterial stains were used: Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli, bacillus subtilis, Candida albicans and Enterococcus faecalis. The agar diffusion method on MullerHilton media was employed. The plates containing media were inoculated with the specified bacterial suspensions. Two standard holes were prepared on each microorganism inoculated plate with a copper puncher and one hole was completely filled with MTA & the other with Ca (OH) 2 . The plates were then kept at environmental temperature for one hour to ensure prediffusion and then incubated at 37 0 C for 24 hours. After 24 hours, the diameters of inhibition zones were measured. Tests were replicated for thirty times for each sample and mean values were taken. Zone of inhibition as measured for MTA and Ca (OH) 2 were statistically analyzed with Student's t-Test and Post Hoc Games Howell Test and were presented as mean ± SD to compare of efficacy of MTA and calcium hydroxide on different microorganisms. Both MTA and Ca(OH) 2 were found to produce zone of inhibition against Staphylococcus aureus (ATCC 25923), Pseudomonas aeruginosa (ATCC 27853), , Bacillus subtilis (BTCC 17 ), and Candida albicans (BTCC 493). MTA showed highest activity against S. aureus and lowest activity against P. aeruginosa which was similar to the activity range of Ca (OH) 2 against the mentioned organisms. But both of them failed to produce any activity against E. coli and. E. faecalis. MTA was found to produce a lower efficacy than Ca (OH) 2 while comparing the zone of inhibition between them and statistically it was significant. Mineral Tri Oxide Aggregate (MTA) showed antimicrobial efficacy against some therapy resistant microorganisms but it did not show antimicrobial efficacy against Escherichia coli and Enterococcus faecalis. MTA was found to produce a lower antimicrobial efficacy than Ca (OH) 2 .

Background: The greatest threats to developing teeth are dental caries and traumatic injury. If pulpal exposure occurs, then a pulpotomy procedure aims to preserve pulp vitality to allow for normal root development. Historically, calcium hydroxide has been the material of choice for pulpotomy procedures. Recently, an alternative material called mineral trioxide aggregate (MTA) has demonstrated the ability to induce hard-tissue formation in pulpal tissue. Objectives: This prospective study was conducted to observe the clinical and radiological findings of pulpotomies done with Mineral Trioxide Aggregate (MTA) &Calcium Hydroxide{Ca(OH)2} and to evaluate success rate of MTA in maintaining pulpal health in teeth with carious lesion. Materials and Methods: In this clinical trial study, 40 primary molars were treated by a conventional pulpotomy technique. They all fulfill the inclusion criteria and gave consent regarding this study. All selected teeth were evenly divided into 2 test groups. In group 1, the MTA pulpotomy (experimental) was performed, whereas in group 2, the conventional Ca(OH)2 pulpotomy (control) was done. The teeth of both groups were finally restored by Glass Ionomer Cement (GIC). The children were recalled for clinical and radiographic evaluations after 3, 6, and 12 months. Result: The follow-up evaluations revealed failure due to pain and swelling detected at 6 and 12 months postoperative evaluations in only 3 teeth treated with Ca(OH)2 and one treated with MTA. The remaining 36 teeth appeared to be clinically and radiographically successful 12 months postoperatively. Calcific metamorphosis was a radiographic finding in 4 teeth treated with MTA and 2 teeth treated with Ca(OH)2. Conclusion: Based on this clinical and radiographical evaluation study of 3, 6, and 12 months follow-up, MTA could be used as a safe material for pulpotomy in cariously and mechanically exposed primary molars and seems to be a suitable alternative to calcium hydroxide. Further research, however, is required to clarify this conclusion. DOI: http://dx.doi.org/10.3329/updcj.v3i1.17981 Update Dent. Coll. j: 2013; 3 (1): 24-31
Reversible pulpitis usually managed by conventional Root Canal Therapy (RCT) in our traditional endodontic practice. Considering biological integrity it is not up to the level of recent views. Even after following most advanced technology, many patients have to suffer for post endodontic events. Therefore, the aim of the study was to evaluate the post-treatment flare-up incidence following application of nano technology based materials (NZOE) considering its biological activity and sealing capability in case of reversible pulpitis.
