Abstract:
Mouth sores, mouth ulcers, or Oral Mucositis (OM) are abrasions of the mucosal layer of the oral cavity. OM is an
important issue for cancer patients since most patients undergoing chemotherapy or radiation therapy face a risk of
developing OM. In some patients these ulcers become so severe that they have to delay or discontinue the cancer treatment.
Th e objective of the project was to conduct a systematic search for most prevalent drugs and type of cancers associated with
OM, a knowledge not well documented. Our research on the extent of cancer drugs leading to OM revealed that about 38 drugs
cause OM in >30% of the patients. Secondly, an analysis of number of drugs that cause OM in diff erent cancers revealed that 20
drugs cause OM in breast cancer, 19 in lung cancer, 16 in non-Hodgkin’s lymphoma, 13 in acute lymphocytic leukemia, 12 in
melanoma and 11 in ovarian cancer. Further, the data from NCI website revealed fi ve cancers – Bladder, breast, colorectal, lung,
and prostate – Encompass a signifi cant population of patients that are suff ering from OM induced by chemotherapy. Oft en
medical professionals circumvent OM by maintaining good oral health e.g., by regular use of oral rinse. However, most oral
rinses contain alcohol and cannot be used by patients with OM. ClÅSYS oral rinses are alcohol free, sulfate free, pH balanced
and contain stabilized chlorine dioxide. Because of its non-irritating nature and antibacterial and sanitizing properties of
stabilized chlorine dioxide, ClÅSYS unfl avored oral rinse is most appropriate choice for circumventing OM in cancer patients.
About 40 customers and 140 Dentists and Hygienists responded to our survey. Most respondents recorded relief using ClÅSYS
oral rinse in conditions such as dry mouth and mouth sores.

Abstract:
Introduction: Student attitudes and behavior towards their own oral health status could refl ect their understanding of the
importance of oral health promotive activities.
Study Objectives: Th is was a qualitative and exploratory study designed to gain a deeper understanding of the extent to which
the undergraduate curriculum could act as an enabler for student oral health self-care practices.
Methods: Data collection comprised of document analysis (curriculum review) and in-depth face-to-face interviews with
undergraduate dental therapy and oral health students and academic staff at the University of KwaZulu-Natal. Ten students
volunteered to participate in the study while fi ve academic staff were purposively selected. A separate interview schedule was
developed for students and staff respectively. Th e emergent themes from document analysis were compared to the analyzed
data from the interviews.
Results: Th e curriculum was underpinned by a strong foundation in prevention, and there was consensus among respondents
that the curriculum met the needs for undergraduate training in preventive dentistry. Th e following themes emerged from
data analysis: curriculum support for self-care practices; depth and scope of clinical training; role of clinical supervisors and
challenges in clinical training. Respondents agreed that the curriculum could infl uence students’ attitudes towards self-care
practices such as tooth brushing and fl ossing but that academic responsibilities and clinical contact time placed constraints on
these practices.
Conclusion: Th e undergraduate curriculum does provide support for enabling student knowledge acquisition and positive
attitudes, but more eff ort is required to enable oral health behavioral modifi cations among students

Raul Eduardo Rivera Quiroga
Antonio Narino University, Colombia
Title: First multicenter characterization of oral yeasts from healthy individuals in Colombian dental clinics
Biography:
Raul Eduardo Rivera Quiroga is a Biologist with a Master’s degree in Biomedical Sciences. He is PhD student at the University of Quindio, Director of Research at the
Faculty of Dentistry at the Antonio Nariño University, Armenia and Member of the Research Group of Health Oral of the same university. He has published 4 papers in
reputed journals and has been an Evaluator of the Colombian Association of Faculties of Dentistry (ACFO), Colombia.
Abstract:
Few studies in Colombia provide an approximation of the prevalence of oral fungal colonization, data related to diff erent species
or their biological, clinical and epidemiological aspects. Considering this, a multicenter study was carried out to identify the
most frequently occurring oral yeasts in healthy adult individuals who attended dental clinics at the Antonio Nariño University
in nine diff erent Colombian cities. Oral rinse samples were obtained from 96 adult healthy patients and cultured and identifi ed by
panfungal PCR sequencing. Association between sociodemographic variables and oral health habits with presence of oral fungi and
mixed colonization was made by a correspondence analysis and contingency table and logistic regression was performed to evaluate a
possible relationship between these variables with a signifi cance of p<0.05. 57.3% of healthy individuals had oral yeast and 21.8% had
mixed colonization. Th e most prevalent yeast was Candida albicans (52%), C. parapsilosis (17.9%) and C. dubliniensis (7.57%). Yeasts
with low frequency (1.5%), included Pichia kluyveri, Rhodotorula mucilaginosa and Geotrichum candidum. Yeasts most frequently
associated in mixed colonization were Candida albicans and Candida parapsilosis. Th e presence of mixed colonization was related
to the use of dental prostheses (P<0.006), dental aparatology (P<0.016) and O´leary index (P<0,012). Th is is the fi rst study that
characterizes oral yeast in a Colombian healthy population, showing a relationship between using dental prostheses and having dental
appliances with having mixed colonies of oral yeasts and reveals a possible synergy between C. albicans and C. parapsilosis.

Title: Establishment of sexual dimorphism in North Indian population by odontometric study of permanent maxillary canine
Biography:
Shalini Gupta BDS, King George's Medical University Lucknow, Uttar Pradesh, India.
Abstract:
Aim: To investigate whether sexual dimorphism can be established by odontometric study of permanent maxillary canine teeth as
well as inter-canine width in north Indian population.
Study Design: Th e study was carried out at Department of Oral Pathology & Microbiology, King George’s Medical University,
Lucknow, India on students and patients reporting at OPD. Out of total 180 subjects examined 90 subjects were female and 90 were
male. Impressions of the upper arch were made using alginate and casts poured in dental stone. Th e mesiodistal diameter of the
crown of permanent maxillary canine both on right and left sides and inter-canine width were measured. From these measurements,
maxillary canine index was calculated. Th e percentage of sexual dimorphism was assessed for all the parameters.
Results: In the present study, the mesiodistal diameter of maxillary canine for both right (p=0.001) and left side (p=0.005) was
signifi cantly higher among male subjects than females, Similar observation was found for inter-canine width too (p=0.0001). However,
the maxillary canine index for right and left was almost similar (p>0.05) for both male and female subjects. Th e sexual dimorphism in
right and left mesiodistal diameters of maxillary canine was 4.2% and 3.6%, respectively. For, inter-canine width it was maximum i.e.
13.7%. However, sexual dimorphism in right and left canine index showed negative values i.e. -2.1% and -0.9% respectively.
Conclusion: Th ere was sexual dimorphism in mesiodistal diameter and inter-canine width of permanent maxillary canine teeth.
Sexual dimorphism was more on right permanent maxillary canine teeth than left permanent maxillary canine

Title: Evaluation of the effect of low level laser therapy after gingivectomy on wound healing
Biography:
Yuksel Kiran has completed his PhD from Gaziantep University. He worked at Zirve University in Gaziantep in Turkey and now he is Head of Periodontology Department
of Ishik Universite in Erbil in Iraq.
Abstract:
Despite the use of lasers in dentistry from the 1980s until today, the use of low level laser therapy laser (laser bio-stimulation) is
not very common in periodontology. Th e aim of this study is to evaluate the eff ect of low power 980 nm diode laser therapy aft er
gingivectomy and in comparison to the non-surgical periodontal treatment on bone healing. Twenty systemically healthy patients
with gingival hyperplasia due to chronic infl ammation in the maxilla or mandibular anterior region at least in 6 teeth symmetrically
were included. Bleeding on probing, gingival index, plaque index, clinical attachment levels were recorded at the beginning and 1
month aft er treatment. Th e patients were underwent scaling and root planning treatment aft er one week of periodontal diagnosis.
Th e curvatures of the gingiva of patients were evaluated for the need of gingivectomy and gingivoplasty and were done for the
patients that need this operation. Th e sides that applied laser therapies were determined by using coin toss and the other sides were
protected from irradiation by putting at least 5 mm thickness of silicon made appliance. the laser of power 4 J/cm (980 nm) were
applied at 0, 1, 3 and 7 days and the surgical area of all the patients at 0, 3, 7 and 15 days were painted with paint mira-2-tone and the
taken photographs by the Image J programs were evaluated. Clinically, Kolmogorov-Smirnov test was used for checking the normal
distribution of wound healing and VAS results. Willcoxon test and Friedman test were used to compare the dependent two groups or
multiple groups, subsequently. Th e results showed that there were no signifi cant diff erences between groups in SD, KAS, PI, GI, VAS
and wound healing but there were a decreased in VAS values at 3 and 7 days. Th e area that applied DDL showed a decrease in pain.
Aft er this study, 980 nm low level therapy upon the clinical parameters could have a positive eff ects when applied aft er gingivectomy
and gingivoplasty.
