Objective: The aim of this in-vitro study was to compare dentinal adaptation of conventional obturating material and GuttaFlow in young permanent teeth of child patients. Materials and Methods: Ten young permanent anterior teeth with closed foramen were selected for the study. Root canal preparations were carried out using a step back technique. The canal was alternately irrigated with 5.25% sodium hypochlorite solution and 17% EDTA and normal saline. After root canal preparation specimens were randomly divided into two groups (n=5). GROUP "A": Obturated with zinc-oxide eugenol sealer and gutta-percha cone using cold lateral obturation technique. GROUP "B": Obturated with GuttaFlow as per the manufacturer′s instruction. The teeth were split into two halves. Five randomly chosen longitudinal split teeth samples each from Group "A" and Group "B" was observed under scanning electron microscope to access the interface between obturating material and dentin at the level of 2 mm from the apex. Results: On statistical analysis the dentinal adaptation (m) of Group A was observed with a mean of 0.52 and standard deviation 0.15, while the value of mean and standard deviation were noted 0.12 and 0.02 for Group B. The "t" value on comparison of Group A and Group B is 5.79 with "P " value of <0.001, which is highly significant. Conclusion: From result of the study it can be concluded Group B samples showed significantly superior seal when compared with Group A. Complete seal was not observed in any of Group A samples.
Intentional replantation of oblique crown-root fracture - A case report
(2012) Manoj Upadhyay; Vinod Upadhyay; Amrit Tandan; Vivek Choukse; Sulabh Kumar
The purpose of this case presentation is to review the clinical procedures involved in intentional replantation of a maxillary central incisor following a complicated crown-root fracture. The treatment of complicated crown-root fractures is often compromised by a fracture below the gingival margin and/or bone. This makes isolation difficult and comprises the hermetic seal that is critical for a successful endodontic treatment. Orthodontic or surgical extrusion with gingivectomy has been suggested; however, these approaches can be expensive, time-consuming, esthetically compromising, and unsatisfactory when the fracture line is deep below the gingiva. Our presentation will discuss the treatment options for such cases and introduce the concept of intentional replantation as an option to manage oblique crown-root fractures in permanent anterior teeth.
Oral ulceration with low dose methotrexate therapy in a psoriasis patient: A case report
(Institute of Medico-Legal Publications, 2014) Suraj Pandey; Vinod Upadhyay; Sunil Verma; Manoj Upadhyay
Methotrexate (MTX) is a well established drug used in the treatment of various neoplastic diseases. The efficacy of MTX against rheumatic diseases was first demonstrated in the early 1950s when aminopterine, a precursor of MTX, was used for rheumatoid arthritis (RA). Recently it has been increasingly used as a once-weekly, low-dose treatment of disorders such as psoriasis and rheumatoid arthritis. As a consequence it is likely that dentists will encounter patients taking this drug in general dental practice. While certain adverse effects of low-dose methotrexate therapy have been described in detail, oral complications have received little attention. Ulceration in oral mucosa can occur as a side effect at any time during the course of methotrexate therapy. This may be due to lack of folic acid supplementation or overdosage due to confusion regarding its once-weekly regime. Even though adverse effects occur in oral cavity, potential still exists for specifically preventing and reversing its toxicity. Here, we are presenting a case report of low dose methotrexate therapy (LDMTX) induced oral ulceration in a patient suffering from Psoriasis. This article also summarises the uses and pharmacology of low-dose methotrexate and the mechanisms that lead to general and oral toxicity. © 2014, Indian Journal of Public Health Research and Development.
