Biography:

Sin-Yeon Cho has obtained endodontic specialist board in Korea in 2013 and completed his PhD from Yonsei University in 2014. He is working in National Health Insurance Hospital Ilsan Hospital in Korea and researching intentional replantation using clinical study, finite element analysis and basic experiment. He has published 3 papers regarding intentional replantation and periodontal ligament regeneration in Journal of Endodontics within the last 2 years.

Abstract:

Intentional replantation is a useful and indispensable procedure that can be applied lastly for tooth preservation in situations where non-surgical endodontic treatment and apical surgery are difficult. However, there are many practitioners who are afraid of the outcome of the procedure because of the rejection due to the operation that accompanies the extraction, and the few studies that can predict the prognosis. I investigated the results of intentional replantation and the major factors affecting the intentional replantation based on the results of analysis of 300 cases performed for 10 years at Yonsei University Dental College Hospital in Korea. Th e purpose of this study is to provide a more precise prediction of the prognosis by analyzing the time of failure and the results of preoperative periodontal status. In addition, we analyzed the outcome factors of extra-oral time and retro-fi lling materials, and discussed the precautions for improving the success rate. We also wanted to share the method for safe extraction with less tooth fracture and root damage. It is the ultimate goal of this lecture that many practitioners will come to intentional replantation with more comfortable mind through such contents.

Her major interest relies on the subject of prosthodontics, temporomandibular disorders and geriatric dentistry.

Abstract:

Quality of Life (QoL) of a patient relates to the satisfaction their denture. Geriatric patient who are well satisfi ed with their daily lives, usually also satisfi ed with their complete denture. Th is study was conducted to assess the QoL pre- and postcomplete denture insertion using a validated Malay language version of Geriatric Oral Health Assessment Index (GOHAI) by single interviewer. It focuses on functional limitation, oro-facial pain, psychological and behavioral impact among patient attended USIM Polyclinic. A sample was taken from 22 edentulous patients and the new denture will be prepared by third year dental students. Th e data comprised of 54.5% male and 45.5% female. Th e mean age was 64.45±5.63 year. Th e QoL of geriatric patient pre-insertion was mostly aff ected in oral function. Th e highest mean for pre-insertion (baseline data) was in functional limitation with mean score 3.18 (SD=1.71) for the problem in chewing. Th e lowest baseline mean recorded were 0.59 (SD=1.18) and 0.59 (SD=0.96) for limitation of contact with people and the used of medication to relieve pain, respectively. Overall, QoL for post-insertion within one to two months was improved. Th e statistical signifi cance with Wilcoxon-Signed-Rank test, pre and 
post-insertion were in oral function (3.18±1.71 and 2.09±1.74, p value=0.03) and psychological impact (2.45±1.26 and 3.50±1.27, p value=0.01). Th e highest changes mean score was in psychological impact with score 1.05. As a conclusion, the placement of complete denture in edentulous patient increase QoL among geriatric patients.

She is the Founder and CEO of Noavadental Research Group, Iran. She has attended many international congresses and she is also a private practitioner and a researcher mostly in orthodontics.

Abstract:

Aim: The aim of this study is to evaluate the stability of innovative interconnected orthodontic mini screw system i.e., Seifi Twin Screws (STS) compared with conventional temporary anchorage device (TAD) configuration by using finite element method.

Materials & Methods: A configuration of titanium mini screw with 8 mm long and 1.6 mm diameter and a cantilever spring inserted on mini screws were designed by a computer aided design software Solidworks 2015. Three-dimensional models were created for each mini screw configurations. The size of each element was 0.4 mm and an isotropic type was used in model construction. Loads in different directions have been applied on models and reactions of system, stress distribution and strains were calculated by finite element based software (ABAQUS 6.14.4).

Results: The finite element analysis was a suitable approximation of clinical simulation in relation to stress distribution and force application. Analyzing the von Mises stress values showed significant lower maximum stress, less undesirable movements and less rotations in the innovated system.

Conclusion: The finite element base analysis demonstrated that the innovated model of STS can be adapted as a clinical orthodontic tool. The usage of innovated system is advantageous in terms of biomechanical stability and lower load deflection rate.

Title: Clinical Measurement Of Maximal Mouth Opening In Children: A Pioneer Method.

Time : 14:20-14:50

Speaker
Biography:

Arun Kumar has completed his Masters in Dental Surgery in the subject of Pedodontics and Preventive Dentistry from Pandit Bhagwat Dayal Sharma University of Health Sciences in India. He is currently working as an Assistant Professor at Post Graduate Institute of Dental Sciences. He has published more than 68 papers in reputed international and national journals.

Abstract:

Measurement of normal maximum mouth opening (MMO) in children is an important diagnostic criterion in the evaluation of the stomatognathic system. The aim of this study was to determine the MMO in children of age 3 to 12 years and to examine the possible influence of age, gender, height and body weight on MMO. Assessment of MMO was accomplished with a modified Vernier Caliper, by measuring the distance between the incisal edges of the upper and lower incisors during maximal mouth opening up to the painless limit. The study consisted of 1383 children, who were randomly divided into two groups based on their dentition: Group-1: Children with primary dentition, Group-2: Children with mixed dentition. The group-1 was sub-grouped based upon age. Sub-group-1: Children with 3 years of age, Sub-group-2: Children with 4 years of age, Sub-group-3: Children with 5 years of age. The group-2 was sub-grouped in sub-group-4: Children of age 6-8years; Sub-group-5: Children of age 8-10 years; Sub-group-6: Children of age 10-12 years. For each subject three readings were recorded in millimeters and the mean value was considered. The age, gender, height and body weight of each child were also recorded at the same time. P value of <0.05 was considered to be significant. The results of the present study revealed that MMO in Indian children were 41.61 mm, 44.9 mm, 46.81 mm, 46.04 mm, 48.53 mm and 52.38 mm for boys and 40.09 mm, 44.22 mm, 46.2 mm, 45.95 mm, 47.27 mm and 52.05 mm for girls at age of 3, 4, 5, 6-8, 8-10 and 10-12 years, respectively. Furthermore, significant associations were observed in between MMO, age, gender, height and body weight.

Abstract:

Objectives: Th e present study evaluated the level of salivary α-amylase (sAA) in healthy individuals and myofascial pain syndrome (MPS) patients and evaluated the reliability of salivary α amylase as a biomarker for pain.
Methods: Following ethical approval, the salivary sample for estimation of amylase was taken using Navazesh method of clinically diagnosed MPS patients (criteria by RDC) (group-1) and age and sex matched control group (group-2). Visual analog scale (VAS) score for each individual was recorded co-related with salivary amylase. Statistical analysis was done using SPSS
soft ware 16.0.
Results: Th e sAA was signifi cantly higher amongst group-1 (149.92±21.1) compared to group-2 (91.18±5.4). Th ere was signifi cant diff erence in VAS among diff erent age groups and sex. Th e salivary α amylase levels progressively reduced in patients as the age increased in group-1. However, mild negative correlation was found between VAS and sAA in group-2.
 
Conclusion: Th e study highlights the sensitivity of sAA as an eff ective marker in assessment of pain severity in MPS patients on the basis of VAS scale. Th e level of salivary α-amylase was signifi cantly correlated with the pain severity assessed by VAS.

She has reviewed research articles in esteemed journals.  

 

Abstract:

Aim: The aim of this study was to find out the therapeutic correlation between cervical dysfunction and myofascial pain dysfunction syndrome (MPDS).

Materials and methods: The study included 46 patients out of which 23 had MPDS with cervical pain (group I), and 23 patients had only MPDS (group II). Detailed history and examination of the patients were carried out, and the factors taken into consideration were pain and tenderness of muscles of mastication and neck muscles, maximum comfortable mouth opening, and cervical range of motion. All the patients were randomly divided and advised physical exercises, light amplification by stimulated emission of radiation (LASER) therapy, and the combination of both exercise and LASER. Patients were assessed for the relief of signs and symptoms of myofascial pain and cervical pain post treatment, every month for 2 months.

Results: Both the groups showed a similar response to all the different treatment modalities. In group I, the patients also had relief in their cervical pain although the treatment was directed for MPDS. Patients from both the groups who were advised LASER and combination of both exercise and LASER showed better response in terms of reduction in visual analog scale, number of tender muscles, and increased maximum comfortable mouth opening post treatment and during the follow-up, as compared with the patients who were advised only exercise.

Conclusion: Patients having cervical pain showed significant improvement comparable with patients having no cervical pain. Hence, the conclusion drawn was that there is a positive interrelationship between MPDS and cervical (neck) pain; MPDS may act as a catalyst for precipitating cervical pain.

Leina Nakanishi

University of Pelotas, Brazil

Title: Experimental one-step self-etch adhesives and bonding to caries-affected dentin

Time : 16:10-16:30

Speaker
Biography:

Leina Nakanishi has completed her graduation from Federal University of Pelotas, Brazil. She is currently pursuing PhD at the School of Dentistry, Federal University of Pelotas, Brazil in Dental Materials.

Abstract:

This study evaluated the shear bond strength (SBS) of experimental one-step self-etch adhesives containing three different concentrations of acidic monomer (GDMA-P) to sound dentin (SD) and caries-aff ected dentin (CAD). Microcosm biofilms were formed over dentin discs and cultivated under anaerobic conditions for 14 days. A biofi lm model was used with intermittent availability of 1% sucrose in a culture medium for 4 hours daily. Six groups were defi ned by diff erent GDMA-P concentrations (5%, 20% and 35%) and dentin type. Bovine dentin discs for each group (n=10) were included in acrylic resin and the adhesives were applied. An elastomer mold with cylindrical orifi ces (1.5 mm diameter) was used to obtain two cylinders of composite resin on the surface. Aft er 24 hours, the cylinders were subjected to SBS test in a mechanical testing machine. Data were analyzed by ANOVA and Student-Neuman-Keuls test (5%). Failure modes were observed under magnifi cation. SBS results were statistically diff erent between substrates. Mean±standard deviations to sound dentin (MPa) were: 5.62±1.90AB (5%), 4.82±2.3B (20%), 6.41±1.91A (35%) and to caries-aff ected dentin were: 3.81±1.46B (5%), 5.91±1.55A (20%) and 3.52±1.3B (35%). The group of 20% GDMA-P showed higher bond strength to caries-aff ected dentin than sound dentin. In all the groups adhesive failures were predominant.
