Evaluation of dermatoglyphic patterns using digital scanner technique in skeletal malocclusion: A descriptive study

The objective of this study was to determine the survival rate of extra-alveolar implants after three months of placement. Also, a questionnaire on the subject's response to the implants were distributed. The records of patients who had extraalveolar implants placed in the department of orthodontics were collected. A total of 32 samples were selected for this study-7 Buccal Shelf (BS) implants and 25 Infra-Zygomatic Crest (IZC) implants. Stability of the TADs were checked using probe and tweezer on the third review. A questionnaire consisting of five questions were distributed to the subjects. Descriptive Statistics was calculated in terms of frequencies and percentages using SPSS software 23.00. Chi-square association test was also performed to associate the extra-alveolar TADs and the discomforts experienced after its placement. The results of this study showed that out of 32 implants only two reported with failure. From a patient point of view, restricted mouth opening, mild swelling was noted during the initial few days of placement. In this study , a high success rate of 93.75% was recorded for extra-alveolar TADs. Patient discomfort was observed initially after the placement of the TADs which subsided over a period of 2 weeks.

“…Our extensive research expertise ranged from epidemiological studies to randomised clinical trials that have been published in reputed journals(felicita, 2017a, 2017b, 2018; felicita, Thirumurthi and Jain, 2017; korath, Padmanabhan and Parameswaran, 2017; krishnan, Pandian and rajagopal, 2017;Charles et al, 2018;Pandian, krishnan and kumar, 2018;reddy et al, 2018;Chinnasamy et al, 2019). This knowledge was instrumental for us to compare the plaque retention in ceramic and metal brackets.…”

Evaluation of Plaque Retention in Stainless Steel and Ceramic Brackets – A Qualitative Comparative Study

To evaluate the plaque retention in stainless steel and ceramic brackets using OHI-S Index and Turesky et al Modified Quigley Hein Plaque Index. The study was done on 40 subjects who were scheduled for fixed orthodontic treatment. The plaque index of subjects was recorded according to the OHI-S index and Turesky et al Modified Quigley Hein Plaque Index methods. Descriptive statistics and Independent sample t-test was used to see the difference in plaque index in factors having two variables. Also chi-square test was performed to associate between the frequency of brushing and the plaque indices.The mean of metal brackets with OHI-S index was 1.36 +0.72 and Turesky Index was 1.58+ 0.74 .Mean of ceramic brackets with OHI-S index was 1.68 + 0.38 and Turesky Index was 1.63 + 0.94. On doing independent-t-tests, t was observed that the ceramic brackets showed higher plaque index scores than metal brackets, but this was not statistically significant. The difference in plaque index between stainless steel and ceramic brackets proved to be statistically insignificant, thereby concluding that in terms of plaque reduction ,any one of the two brackets could be used.

“…Previously our team has done extensive research that ranged from epidemiological studies to randomised clinical trials that have been published in reputed journals. (Felicita, 2017a(Felicita, , 2017b(Felicita, , 2018Felicita, Thirumurthi and Jain, 2017;korath, Padmanabhan and Parameswaran, 2017;krishnan, Pandian and Rajagopal, 2017;Charles et al, 2018;Pandian, krishnan and kumar, 2018;Reddy et al, 2018;Chinnasamy et al, 2019) .we have also done clinical trials on bond strength (Samantha, 2017). We wanted to compare the shear bond strength of the new adhesive-Brace Paste with that Enlight -an orthodontic adhesive produced by Ormco and hence this study.…”

A Comparison of Shear Bond Strength of two Visible Light Cured Orthodontic Adhesives -An In-vitro Study

2020

The aim of the study was to evaluate and compare the shear bond strength of the brackets bonded with two different orthodontic light cure adhesives.Twenty extracted human premolars were divided into 2 groups. Premolar brackets were bonded to the tooth specimens in each group with their respective adhesive according to the manufacturer's instructions. Group1-bonded with Enlight (ORMCO) and Group2-tooth specimen bonded with Brace Paste (American Orthodontics) and then examined for shear bond strength. The teeth were placed in INSTRON universal testing machine at crosshead speed of 0.5 mm/minute, and the shear force to remove the brackets was recorded. The independent t test revealed that there was no significant difference between the shear bond strength of the two groups. The mean shear bond strengths of two adhesive systems showed no significant differences.(P value-0.068) Thus either of the composite adhesives would provide similar results with respect to the bond strengths.
