COMPARISON OF THE ADAPTABILITY OF TWO FISSURE SEALANTS IN VARIOUS TOOTH FISSURE MORPHOLOGY PATTERNS: AN IN VITRO EXPERIMENTAL STUDY
Journal Title: Journal of Ayub Medical College Abbottabad - Year 2019, Vol 31, Issue 3
Abstract
Background: This study was conducted to compare the adaptation of resin-based sealants with that of Resin modified glass ionome-based sealants in various tooth fissure morphologies. Methods: It was an in vitro experimental study done at the Dow University and NED University, Karachi, Pakistan. Ten extracted human molars were randomly assigned to two groups, (n=5) each. Fissure sealant material (Resin based sealant or resin modified glass ionomer-based sealant) was applied on the occlusal surface of the tooth according to manufacturer’s recommendations. Specimens were thermocycled and then sectioned into three longitudinal parts in the bucco–lingual direction. Specimens were examined using scanning electron microscope for the adaptation of the sealant in the occlusal fissure. Mann-Whitney –U test and Kruskall-Wallis test were applied to compare the adaptability scores of sealant materials in the tooth fissure. Level of significance was kept at 0.05.Results: There were no significant differences in the adaptability scores among U-shaped (p-value=0.35), V-shaped (p-value=0.89), IK-shaped (p-value=0.52), I-shaped (p-value-=0.41) and Y-shaped (p-value=1.00) fissure patterns. Similarly, there were no significant differences observed between the resin-based sealant (p-value=0.95) versus RMGIC based sealant (p-value=0.63) for the adaptability scores in various tooth fissure morphologies. Conclusions: No significant difference was found between resin-based sealants and resin modified glass ionomer-based sealants for the adaptation in various tooth fissure patterns.

ASSOCIATION BETWEEN VARIATIONS IN SELLA TURCICA DIMENSIONS AND MORPHOLOGY AND SKELETAL MALOCCLUSIONS
Background: The growth of sella turcica is completed early in life, therefore it can be used as a stable landmark for the prediction of future skeletal malocclusions. This early diagnosis may help in planning less compli...
