ABSTRAKLaju aliran saliva merupakan salah satu faktor penting pembentukan karies. Laju aliran saliva yang adekuat dapat mencegah proses pembentukan karies dan perkembangan penyakit periodontal dan infeksi oral. Status gizi adalah salah satu faktor yang mempengaruhi laju aliran saliva. Salah satu parameter status gizi adalah Body Mass Index (BMI). Tujuan penelitian ini adalah untuk mengetahui hubungan antara BMI dengan laju aliran saliva. Penelitian ini merupakan penelitian observasional dengan pendekatan crosss sectional study yang dilakukan pada 24 orang mahasiswa Fakultas Kedokteran Gigi Universitas Andalas yang berumur 18 -25 tahun yang memenuhi kriteria inklusi dan eklusi. BMI ditentukan dengan rumus BMI dengan satuan kg/m 2 . Laju aliran saliva ditentukan dengan metode Sialometry Navazesh (2008) dalam satuan ml/menit. Analisa data univariat dilakukan untuk mendeskripsikan masing-masing variabel, untuk melihat distribusi normal (p > 0,05) dilakukan uji normalitas Kolmogorov Smirnof test. Setelah terbukti variabel terdistribusi normal, selanjutnya dilakukan uji korelasi regresi untuk mengetahui hubungan antara BMI dengan laju aliran saliva. Berdasarkan hasil uji korelasi didapatkan rata-rata BMI mahasiswa Fakultas Kedokteran Gigi Universitas Andalas adalah ± SD = 24,50 ±6,02 kg/m 2 dan laju aliran saliva adalah ± SD = 0,29 ± 0,10 ml/menit. Hubungan antara BMI dengan laju aliran saliva menunjukkan hubungan sedang dengan arah negatif (r = -0,451). Hasil uji regresi linear diketahui bahwa Laju Aliran Saliva = 0,404 -0,008*(BMI). Koefisien regresi BMI 0.008 menyatakan bahwa setiap penambahan 1 BMI maka akan menurunkan laju aliran saliva sebanyak 0,008 ml/menit. Penelitian ini menyimpulkan bahwa terdapat hubungan bemakna antara Body Mass Index (BMI) dengan laju aliran saliva. Pada kelompok obesity memiliki laju aliran yang lebih rendah dibandingkan individu non obese (underweight, normal weight dan overweight). Sedangkan laju aliran saliva pada kelompok underweight tidak ditemukan penurunan laju aliran saliva. Gi. Ind. Desember 2015; 1(2): 156 -162 ABSTRACT: Relationship between Body Mass Index and Saliva Flow Rate (A Study in Faculty of Dentistry, Andalas University). Saliva flow rate is an affecting factor of caries formation. Adequate saliva flow rate can prevent cariess formation process and progression of periodontal disease and oral infection. Nutritional status is known as an influencing factor of saliva flow rate. The parameter of nutritional status is Body Mass Index (BMI). The purpose of this study is to discover the relation between BMI and saliva flow rate in College Students of the Dentistry Faculty Andalas

Background: The motivation for selecting a dentist career is the complex consideration. Knowing and understanding dental students' motivation is important for institutions to manage learning systems to create dentists that can fulfill the needs of the community. Purpose: to describe the motives and perceptions of undergraduate and postgraduate dental students attending Faculty of Dentistry, Andalas University. This study was conducted to 120 academic and clinical students in this institution. The students were instructed to fill a questionnaire consisting of 25 questions. Eight questions were scored from 1 to 2 , 1 question was a multiple choice question and the rest were scored from 1 to 4. The data were tabulated by Microsoft Excel, factor analysis was tested by SPSS software. Results: Fifty three percent of students chose dentistry in the first place. The most common factors choosing dentistry are internal or external motivation, profession, and remuneration. Dental students showed a strong tendency to pursue higher study and managing private dental clinics. Conclusion: humanity, flexibility, and financial status were found to be important motivating factors. Hence, it may be a good idea to establish educational programs in the faculty to educate students based on their career choices.

Background: Periodontal disease is preceded by an inflammation in the gingiva surrounding the teeth called gingivitis. It is an untreated gingivitis causing hard tissue damage (alveolarbone). This inflammation increases the activity of ALP enzyme. Zinc is an Alkaline Phosphatase co-factor. Aim: This study aims at proving the connection between Alkaline Phosphatase (ALP) and zinc within the food of the Minangkabau people in West Sumatra, Indonesia. 60 samples are involved in this study. ALP level is tested by using ELISA technique. Zinc level in Minangkabau food is measured by Food Frequency Questionnaire (FFQ). Data is analyzed by means of univariate to describe each variable , Kolmogorov Smirn of Test is used to see the normal distribution ( p > 0.05). Result: Pearson correlation is conducted to see the correlation between ALP level and zinc clevel in Minangkabau food. The study reveals that ALP activity is higher in mild periodontitis compared to mild gingivitis and healthy control. Zinc level is significantly lower in mild periodontitisthanin mild gingivitis and healthy control individuals. The relation between ALP and zinc level indicates strong correlation with positive direction (r = -0,884). Conclusion: Zn decreases ALP activity and shows that zinc complement has both preventive and curing effects in periodontitis patients.

Introduction: Gingivitis is a mild form of periodontal disease with clinical signs of gingiva that is red, swollen and bleed easily without alveolar bone damage. MMP-8 has been linked to the diagnosis of periodontal disease, the severity of periodontal inflammation, the development and follow-up of treatment. Zinc can be a combination in periodontal therapy after scaling root planning. The author aims to determine the effect of zinc supplementation and zinc mouthwash on MMP-8 levels after scaling root planning in gingivitis patients. Methods: Subjects were teenage students aged 16-18 years, suffering from moderate gingivitis and severe gingivitis based on the parameters of the Gingival Index and Bleeding on Probing examination. The

Background: This paper discusses palatal rugae patterns and their contribution in the identiication of individuals and the determination of family lineage in West Sumatera, Indonesia. Identifying an individual is a prerequisite for the issuance of death certiicate as well as for personal, social and legal reasons. The most common techniques used in this context are dental records, ingerprint and DNA comparisons. However, under certain circumstances, these cannot always be used. But interestingly, palatal rugae patterns are preservable because they are impervious to disasters and hostile conditions and can be used as alternative human identiication techniques. This paper argues that the study of palatal rugae (rugoscopy) cannot only help to reveal a person's identity but also to determine their family lineage. Objective: The present study was carried out to ascertain whether there is any hereditary patterns in the palatal rugae patterns of the mother, father, and the ofpring in one family. Method: This is a cross sectional study of 48 samples consisting of 12 families in Luhak Nan Tigo. The parents and ofspring (son or daughter) of each family were randomly selected. Palatal rugae impression was recorded using alginate while palatal rugae patterns were noted and recorded. One Way ANOVA test (SPSS 17) was used as statistical anaysis method. Result : The study shows that there is a signiicant similarity in curved, wavy, and straight rugae patterns (p> 0.05) as well as in primary, secondary, and fragmented rugae based on the family tie between the father, mother, sons and daughters of the Minangkabau ethnic. Unilateral and circular rugae tests are insigniicant (p <0.05). Conclussion : This is a cross sectional study whose results are only based on 48 samples consisting of 12 families, therefore further studies are needed with a larger sample quantity. The results of this study indicate the role of factors in the patterns of palatal rugae.
