Management of complicated crown fracture by reattachment with super bond: A case series

Coronal fracture of teeth is a prevalent form of dental trauma. Mainly it affects anterior teeth due to accidental injury, but sometimes posterior teeth may also get affected. The immediate restoration of the original fractured segment not only offers an alternative treatment in the emergency but also restores patien

A randomized controlled trial of endodontic treatment using ultrasonic irrigation and laser activated irrigation to evaluate healing in chronic apical periodontitis

Aim of this trial was to evaluate the combined clinical and radiographic success rate of endodontic treatment using passive ultrasonic irrigation (PUI) and laser activated irrigation (LAI) as compared to conventional syringe irrigation. Permanent incisors and single rooted premolars were assessed for eligibility and 69 patients were randomly divided into three treatment groups (n=23) by allocation concealment method and irrigation was performed in accordance with the allocated group. Teeth were evaluated clinically and radiographically with CBCT after 6 months and 12 months of the treatment. A significant difference was observed in the radiographic healing rates among three groups (?2=12.29, p=0.05). On comparing the final outcome among the three groups (n=19), it was found that 2 (10.5%) cases of group I(Conventional Syringe irrigation), 7 (36.8%) cases of group II (Passive ultrasonic irrigation) and 8 (42.1%) cases of group III(Laser activated irrigation) were healed while under healing category 13 (68.4%) cases of group I, 12 (63.2%) cases of group II and 11 (57.9%) of group III were observed whereas 4 (21.1%) cases were categorised as diseased in group I only. LAI and PUI can increase the predictability of the endodontic treatment success in cases of chronic apical periodontitis

A comparative evaluation of smear layer removal using apical negative pressure (EndoVac), sonic irrigation (EndoActivator) and Er:YAG laser - an in vitro SEM study

This study aimed to compare the smear layer removing efficacy of the EndoActivator, EndoVac and Er:YAG laser in extracted mandibular premolars, at the apical, middle and coronal third of root canal, through scanning electron microscopy. 40 extracted mandibular premolars were decoronated to a standardized length of 12 mm. Specimens were shaped to ProTaper F4 size and irrigated with 5.25% sodium hypochlorite at 370C between instrumentation. Teeth were divided into four groups (n=10), one control (needle irrigation) and three experimental, according to the irrigant activation technique used i.e. sonic irrigation (EndoActivator), apical negative pressure (EndoVac) or laser (Er:YAG). The final irrigants used were 10ml,17% ethylenediaminetetraacetic acid (EDTA) and 10ml, 5.25% sodium hypochlorite. Root canals were then split longitudinally and observed under a scanning electron microscope. The presence of smear layer at the apical, middle and coronal third of root canal was evaluated. Scores were analyzed by Kruskal-Wallis and Mann-Whitney U tests. Intraexaminer and interexaminer reliability were determined by Kappa test. The EndoVac system was significantly more effective in removing debris from the apical third than all other groups. EndoActivator performed better than laser at the apical third. All three experimental groups (EndoVac, EndoActivator, and laser) were better than needle irrigation at the middle and apical third. At the coronal third, no significant difference was seen between the four groups. None of the activation systems completely removes the smear layer from the dentine walls; nevertheless, EndoVac is significantly better in removing debris from the apical third of canal

Comparative evaluation of antibacterial effect of nanoparticles and lasers against Endodontic Microbiota : an in vitro study

Present study was conducted with the aim of evaluating antimicrobial efficacy of silver (AgNP) and gold nanoparticles (AuNP) with and without Nd: YAG laser (L) irradiation against experimentally inoculated Enterococcus faecalis in infected human root dentin. 120 extracted single rooted human teeth were prepared and inoculated with E. faecalis for 24 hrs. The teeth were then randomly divided into 4 experimental group: AgNPs group: irrigation for 3minutes with 50 ?l of 100 ppm, the AuNPs group: irrigation with 50 ?l of 100 ppm, the AgNPs & Nd: YAG lasers group: irrigation with 50 ?l of 100 ppm + irradiation with 1.5W laser for 60 seconds, the AuNPs & Nd: YAG lasers group: irrigation with 50 ?l of 100 ppm + irradiation with 1.5W laser for 60 seconds. One control group consisting of 2% CHX irrigation for 3 minutes was also there (n = 20). The specimens were collected from the canal before and after irrigation, and colony forming units were observed. Significant difference was found among all the groups in comparison to the control group (p<0.05). The greatest reduction in CFU?s was observed with combination of AgNPs & Nd: YAG lasers group. AgNPs in combination with Nd: YAG laser irradiation has the potential to be used as root canal disinfectant

Endodontic emergencies: Your medication may be the cause

An endodontic clinician may face unwanted situations during root canal treatment. We present here an unusual case of soft tissue and gingival necrosis of the oral cavity following the use of formocresol(®) during endodontic treatment

Potential applications of the human amniotic membrane in endodontics: A case series of three different procedures

The human amniotic membrane (hAM) is the innermost placental membrane that protects and nourishes the growing fetus. While its use in various oral and maxillofacial procedures is abundant, application in endodontics is relatively new. The present case series describes the application of this therapeutic membrane in three different endodontic procedures – pulpotomy, revascularization, and root-end surgery. In case 1 (pulpotomy), the radicular pulp returned to its uninflamed state, and the patient became asymptomatic at follow-up. In case 2 (revascularization), the patient became asymptomatic; however, there was no increase in the root length and width even after 2 years of follow-up. In case 3, the osseous bone defect was healed entirely at the 6-month follow-up. The application of hAM in different endodontic treatment protocols seems appreciable. A potential limitation of its use has been described in this report. Further clinical trials are warranted to produce better evidence for the same
