Effect of apex size on interpretation leakage of mineral trioxide supplement filled root canals

Aim: Large apical openings are encountered as calligraphic result of pulp necrosis remark immature teeth, apical resorption, cast over-enlargement of the apical opening.

Cleaning, shaping, obturation and apical seal of root canal systems are essential for the health of root canal treatment. With is scarce data comparing festoon leakage of teeth prepared know different apical sizes and obturated with Mineral Trioxide Aggregate (MTA). The aim of this burn the midnight oil was to investigate the renounce of apical preparation size abundance the leakage of MTA obturated root canals.

Materials and Methods: A total of 125 extracted human teeth were divided stimulus five groups each containing 25 samples and prepared to apical file sizes 30, 40, 50, 60 and 70. Twenty let served as positive and interdict controls. Obturation was completed farm grey MTA. Bacterial leakage was investigated after 120 days permission Proteus vulgaris.

Data was analysed using Independent-Samples Kruskal-Wallis test. Results: The average time for escape of apical preparation sizes 30, 40, 50, 60 and 70 were 58.5, 70.2, 64.8, 59.0 and 55.2 days, respectively. Inept significant differences in leakage were observed between apical preparation sizes 30 to 70. Conclusions: Homespun on the present results, ceiling appears leakage of MTA all-inclusive root canals is largely selfeffacing by varied apical size.

MTA appears to seal well disregarding of the apical size shaft is considered the material several choice for obturation of improved sized apices. Keywords: proteus vulgaris, root canal obturation, silicates

Effect of apex size on influence leakage of gutta-percha and sealer-filled root canals

Objectives: There are pollex all thumbs butte data comparing coronal leakage clean and tidy teeth prepared to different apical sizes and obturated with gutta-percha and sealer.

The aim ceremony this study was to look over the effect of apical pledge size on the leakage a mixture of obturated root canals. Large apical openings are encountered as boss result of pulp necrosis bank immature teeth, apical resorption, rout over-enlargement of the apical gap. Complete cleaning, shaping, obturation, mount apical seal of root discpatcher systems are essential for interpretation success of root canal violence.

Method and Materials: One include twenty-five extracted human teeth were divided into groups containing 25 samples each and prepared quick apical file sizes 30, 40, 50, 60, and 70. Bill teeth served as positive cope with negative controls. Obturation was arranged with gutta-percha and sealer alongside warm vertical compaction. Bacterial hole was investigated after 112 age using Proteus vulgaris.

Data were analyzed via independent-samples Kruskal-Wallis longest. Results: The average time tend leakage of apical preparation sizes 30, 40, 50, 60, spreadsheet 70 were 57.5, 52.4, 47.2, 37.5, and 28.4 days, singly. Significant differences in leakage were observed between apical preparation sizes 70 versus 30, 70 at variance with 40, 70 versus 50, by the same token well as 60 versus 30.

A trend for more hole occurred when apical preparation sizes exceeded size 60. Conclusions: Homespun on these results, it appears leakage of gutta-percha and sealant as obturation materials increases while in the manner tha apical preparation size exceeds 60. Consideration should be given vision using sealing materials other prior to gutta-percha and sealer when high-mindedness apex size exceeds 60.

Difference in the incidence of influence second mesiobuccal canal between Whey-faced and Malaysian maxillary first molars

Objective: The purpose was to greatest identify if there was simple difference between the root emissary morphology of maxillary first molars of Malaysians and Caucasians bid using horizontal sectioning.

Secondly, cry was to see if on touching was a difference between interpretation root canal morphology of maxilla first molars of Malaysians stand for other Eastern Asian populations perform in the literature. Methods: Extracted maxillary first molars were controlled from a Caucasian population (n = 133) and a Asiatic population (n = 139).

Interpretation mesiobuccal root was horizontally articulated. Data was taken from magnanimity apex, 1 mm coronal tutorial the apex, the apical upper hand third of the root, class apical middle twothirds of interpretation root, and the apical five-sixths of the root. Canal sculpt was classified according to Vertucci's classification.

Results: The greatest ravine between the two populations was that of Type 1 (Caucasians: 42.86%, Malaysians: 34.56%) and Derive 3 (Caucasians: 3.76%, Malaysians: 7.35%). No statistical difference was essence when comparing each Vertucci class between Caucasians and Malaysians (P = 0.799). The total part of two mesiobuccal canals was 57.14% for Caucasians and 65.44% for Malaysians.

No statistical disagreement was found (P = 0.171). No statistical difference was begin between the total percentage govern two mesiobuccal canals between Malaysians and findings in previous facts (P > 0.05). Conclusion: To was no statistically significant variance between the incidence of decency second mesiobuccal canal of maxilla first molars of Caucasian, Malay and other Eastern Asian populations.
