Abstract:
Introduction: Increased orthodontic treatment duration has always been a subject of concern for both orthodontists and patients. Various methods have been evaluated in the past to expedite tooth movement each having its own merits and demerits. Platelet rich plasma is being used as a valuable adjunct to promote tissue regeneration in various specialities of medicine and dentistry. Therefore the objective of this trial was to evaluate the effect of platelet rich plasma on rate of orthodontic tooth movement
Methodology: This randomized controlled trial was conducted on 2 parallel arms. It was conducted at Orthodontics department, Armed Forces Institute of Dentistry, Rawalpindi, from May 2018 to July 2019. Ten patients were included in this study who required extraction of maxillary frist premolars for orthodontic treatment. After alignment and extraction of maxillary first premolars, canine retraction was started with closed Ni Ti coil spring on both sides of the maxillary arch on a 17 x 25 SS wire. PRP from 5 ml blood was prepared and 60 units were injected into the buccal vestibule of patient on one side of the arch which was the experimental side. The other side served as the control side . Random allocation to be control or experimental side was done by lottery method. The distance between the lateral incisor and the canine was measured on both sides before starting canine retraction. The same measurements were recorded after four weeks of retraction. The difference between pre and post retraction measurements was recorded. The difference in the rate of canine retraction between experimental and control sides was compared using Wilcoxon signed rank test considering p value of <0.05 significant and results were analyzed using spss 21 software
Results: Ten patients were randomized to control and experimental groups. Results were analysed on intention to treat basis. The mean rate of tooth movement on the control and experimental sides was 0.83±0.64mm and 2.14±1014mm respectively. There was an overall increase of 1.603 ± 0.5037 mm movement per month on the experimental group. No harms were detected.Thus there was an approximately a 3 fold increase in rate of orthodontic tooth movement with a ratio of 2.91:1 in experimental and control group.
Conclusion: Platelet rich plasma is an effective minimally invasive technique for increasing the rate of orthodontic tooth movement.

Abstract:
Introduction and Objectives: The presence of impacted canine (IC) can cause malocclusion or pathologic problems in adjacent teeth. Considering the importance of identifying the canine and its adjacent root resorption in orthodontic treatment, as well as the lack of studies, the aim of this study was to investigate the relationship between the position of maxillary IC and adjacent root resorption (ARR) in Cone Beam Computed Tomography (CBCT).
Methodology: In this study, 30 radiographic clichés were evaluated with the New Tom software. The angles between the longitudinal axis of the maxillary IC and the longitudinal axis of the central and lateral teeth adjacent to IC, and the angle between the longitudinal axis of the maxillary IC with the functional occlusal plan were measured, and then the data were analyzed for investigation the relationship between the position of maxillary IC and the ARR.
Findings: Women with the prevalence of 73.3% and the age group of 15-14 years with the prevalence of 36.7% had the most prevalent of IC. Position of IC was palatal in 80% of cases. 13.4% of the samples had degrees of ARR. In addition, age and gender had no significant correlation with the ARR, and the relationship between unilateral or bilateral of IC and ARR and relationship between position of IC and ARR were not statistically significant.
Conclusion: The results of this study demonstrated that the ARR of IC is independent of age, sex, unilateral or bilateral and position of impaction.

Title: Prevalence of Tongue Lesions among Dental Students in Faculty of Dentistry Universitas Padjadjaran
Biography:
Meelaashah is a dental student who is studying in University of Padjadjaran, Indonesia. She has completed her Sarjana Kedokteran Gigi (SKG) which is the first degree before entering the clinical practice. She has done her research in oral medicine titled “Prevalence of Tongue Lesions among Dental Students in Faculty of Dentistry Universitas Padjadjaran”.
Abstract:
There are various lesions can be found on the surface of the tongue. Around the globe, many researches has conducted to observe the condition of the tongue lesions but not in Indonesia that focuses on dental students. This research is carried out to obtain the prevalence of tongue lesions among dental students in Faculty of Dentistry Universitas Padjadjaran.
The study used descriptive method and total sampling. The research was conducted on 250 clinical dental students in Rumah Sakit Gigi dan Mulut Unpad. Tongue lesions were examined and the data were recorded. The data were presented with simple frequency distribution table.
The result showed that the prevalence of tongue lesions is 68%. The types of tongue lesions found are fissured tongue (2.9%), coated tongue (13.5%), physiologic pigmentation (0.6%) and crenated tongue (46.5 %). The prevalence of combined tongue lesions are fissured tongue and coated tongue (4.7%), fissured tongue and crenated tongue (8.2%), geographical tongue and coated tongue (0.6%), geographical tongue and crenated tongue (1.2%), coated tongue and crenated tongue (21.2%) and physiologic pigmentation and crenated tongue (1.2%).
The conclusion of this study stated that the prevalence of crenated tongue is the highest among dental students followed by coated tongue, fissured tongue and physiologic pigmentation. For combined lesions, coated tongue and crenated tongue has highest prevalence followed by fissured tongue and crenated tongue, fissured tongue and coated tongue, geographical tongue and crenated tongue, physiologic pigmentation and crenated tongue and the least is geographical tongue and coated tongue.

Title: Comparison of the Outcomes of Different class II Treatments Protocols using ABO-OGS, PAR Index and IOTN

Abstract:
Introduction
Various treatment modalities are used to treat skeletal class II malocclusion. Treatment success should be evaluated to ensure that each case is finished ideally. Therefore, this study was aimed to compare the outcomes of different skeletal class II treatment modalities.
Materials and Methods
A cross-sectional study was conducted using pretreatment and post-treatment dental casts, photographs, and radiographs of 135 subjects equally divided into Clark’s Twin Block (CTB), upper first premolars’ extraction (UPE), and class II elastics (C2E) treatment modalities. The post-treatment casts and radiographs were scored according to American Board of Orthodontics-Objective Grading System (ABO-OGS). Peer Assessment Rating (PAR) Index and Index of Orthodontic Treatment Need (IOTN) were assessed using pretreatment and post-treatment casts. Wilcoxon-Signed Rank test was used to compare the pretreatment and post-treatment malocclusion scores. Mann-Whitney U test and Kruskal-Wallis test were used to compare the scores among different treatment modalities. Level of significance was kept at p ≤ 0.05.
Results
The ABO index indicated that cases treated with C2E had the greatest incidence of treatment failure (40%) followed by CTB (33.3%), and UPE (20%). The changes in the PAR scores indicated a significant (p < 0.001) improvement for CTB (93.2%), UPE (90%), and C2E treatment (87.2%). Similarly, changes in the pretreatment and post-treatment IOTN-DHC and IOTN-AC scores were significant (p ≤ 0.001) for all the treatment modalities.
Conclusions
All class II treatment modalities show significant changes after orthodontic therapy using different indices. However, treatment with C2E has shown less improvement than the others.
