Biography:
Jiin Huey Chern Lin received her Ph.D. from Northwestern University Dept. of Biological Materials (Chicago, Illinois). She is Director of the Center for Biomaterials
Research, National Cheng-Kung University (Tainan, Taiwan) and Technology Founder/CTO of Joy Medical Devices Corp. (Luzhu, Kaohsiung). Professor Chern Lin

Abstract:
A series of synthetic, inorganic, highly osteoconductive and fully resorbable calcium-based bone substitute materials
(Ezechbone®) has been developed by a joint research project of National Cheng-Kung University and Joy Medical Devices
Corporation of Taiwan. Reported in this presentation include non-clinical performance and clinical follow-ups for diff erent
applications. Ezechbone®granule is a highly porous granular product characterized by its high resorption rate (totally resorbed
and replaced by new bone in 3-6 months), while Ezechbone®cement is featured by its unique non-dispersive behavior when
contacting blood/body fl uid without the need of any polymeric or another binder additive. Th is cement can be applied directly
aft er forming a paste or injected into bone void via a minimally invasive procedure. Th e safety and effi cacy of these medical
devices are confi rmed by a series of chemical/physical characterization and biocompatibility tests such as cytotoxicity, subchronic
toxicity, intracutaneous reactivity, skin sensitization, ocular irritation, endotoxin test, hemolysis test, genotoxicity, and
implantation. Animal models for implantation tests include SD rat femur body, New Zealand white rabbit femur condyle and
mandible, Lanyu pig mandible, and osteoporotic goat spine. Th e histopathologic examination indicates that the implant is
always intimately integrated with surrounding bone tissues. Majority of Ezechbone® Granule is readily resorbed and replaced by
new bone generally in a one-to-one resorption manner as early as 4W post-implantation. Th e early-stage new bone formation is
far faster in Ezechbone® Granule group than in an autologous group. Clinical case reports include sinus lift , ridge augmentation,
frontal bone augmentation and treatment for various types of fractures.

Abstract:
A hospital-based cross-sectional study was undertaken on diabetic patients aged between 19-79 years during the period of
April 2004 – December 2004 in the department of Pedodontics (former Preventive and Children Dentistry), Bangabandhu
Sheikh Mujib Medical University, Dhaka and at Diabetic Clinic at Rajshahi. Th is study was conducted to evaluate how tobacco
and betel nut along with other study parameters aff ect periodontal health in diabetics in the context of Bangladesh. Th e study
population included 34 males and 47 females. Based on the study results, all study subjects brushed their teeth regularly and
mostly with paste and brush. However, consistently the periodontal health in the middle sextants displayed better condition
than the posterior sextants. From this view, it can be presumed that in the middle sextants, the pocket formation is not usually
common maybe because the anterior region (middle sextant) is easy to clean and have more opportunity to catch extra exposure
to oxygen in comparison to posterior sextants. Th e present study also showed an interesting and a controversial connection
between periodontitis and tobacco and betel nut chewing among targeted diabetic patients. Th ough little is known about the
eff ects of tobacco and betel nut among diabetics, it is almost well established that tobacco and betel nut are harmful to oral
health even for people without diabetes. However, a person with diabetes who use tobacco or chew betel nut or both is at much
greater/higher risk for periodontal disease than a person who is non-diabetic. Even though this recent evidence supported the
role of tobacco as a potent risk factor for the edentulous mouth or in the mouth where less than two or three teeth are present
but this study gives a contrast result regarding periodontal health. Present study detected that gum bleeding is totally absent
among both the betel nut chewers as well as tobacco users and also they are not insulin dependent whereas most participants
of this study who are neither tobacco users nor betel nut chewers are insulin dependent. In this regard, data of the current
study indicate that tobacco and betel nut might be potentially helpful to control blood sugar among the diabetic cohort. It is
perceived that the betel nut has an antibacterial property and so it can suppress the salivary organisms for prolonged betel nut
users. In ancient period, for treating bleeding gums in Indian medicine betel nut is also used. In contrast, it might be possible
that because of using tobacco blood circulation gum may be hampered that eventually results in less or no gum bleeding.
Th erefore, it requires detecting the association between the higher periodontal index with the use of tobacco and betel nut
chewing habits. Since the sample size in this study was relatively small (81) and not representative, data have to be interpreted
with care. Th erefore, in order to validate these fi ndings a longitudinal study could be a good option to elucidate this perception more concretely.
Biography:
Aleksandar Gulin has completed his PhD at the age of 28 years from University of Zagreb School of Dental Medicine and Orthodontic residency as well from
University of Zagreb School of Dental Medicine. He is running his own private practice from 2011. He is a vice president of Croatian Society of Orthodontics. He is
lecturing in Croatia and internationally as well.
Abstract:
Today’s orthodontic practice is not driven by professional clinical decisions only; it is also highly infl uenced by the patient’s
diff erent demands. Nowadays the internet has enabled a direct access to information, thus enabling the patient to become
more easily self-informed and determined in his/her requests. In this lecture, presentation of possibilities of combining
corticotomy and its RAP phenomenon, TADs and cortical plates, shall be based on real cases with “what if…?” moments, when
the patients posed diff erent kinds of demand, such as: What if we try to save this tooth? What if I don’t want to extract my
premolars? What if we only help my GP to place implants and prosthetics by segmental orthodontics instead having braces on
all teeth? What if we do it by shortening the treatment to 9 (or 3) months because otherwise, I cannot accept it? 5 cases will be
presented in about 45 min long lecture.
