“…11,12 Moreover the caries PI = Plaque Index; GI = Gingival Index prevalence of the 12-year-old children in this study (84%) with a mean decay of 2.9 teeth are far exceed those in Hong Kong with 21% prevalence and 0.16 of decay score and also the ethnic minority groups in China whom decay prevalence and mean decay score of 35% and 0.6 respectively. 13,14 The highest prevalence of caries in 5-year-old children was found in the maxillary incisors. Longer duration of exposure to cariogenic challenge according to the chronological tooth eruption sequence might be the cause of this prevalence.…”

Jakarta is the capital city of Indonesia which is surrounded by its satellite cities Bogor, Depok, Tangerang, Bekasi. Nonetheless, scarce information are available of the current oral health of children. Objective: The study aims to describe caries and gingival status among 5 and 12 years old children in Jabodetabek. Jabodetabek is an abbreviation of Jakarta, the capital city of Indonesia, and the satellite cities in its surrounding (Bogor, Depok, Tangerang, Bekasi). Methods: The survey was done in 2014 and had already got ethical approval. Design of this study was crosssectional. Subjects were 5-year-old and 12-year-old Indonesian children living in Jabodetabek, selected using cluster sampling method. One trained examiner performed the clinical examination. Caries experience was measured using DMFT index, severity of decayed teeth was assessed using PUFA index, gingival status and oral hygiene were measured by Loe and Sillness modified index. Results: A total of 390 5-year-old and 458 12-year-old children with balanced proportion between girls and boys participated in the survey. The prevalence of caries experience among the 5-yearold children and 12-year-old children were 90% and 84% respectively. The mean DMFT and DT scores among the 5-year-old children and 12-year-old children were 7.5±5.5 and 6.8±4.8; 3.2±2.2 and 2.9±2.1 respectively. Pulp involvement were apparent in 45% and 23% of caries in 5 and 12-year-old children respectively. Most children, 45% 5-year-old children and 92% 12-year-old children had substantial amount of plaque. Moreover, 68% 12-year-old children had gingivitis. Conclusion: Dental caries were prevalent among 5 and 12-year-old Indonesian children in Jakarta and its satellite cities. The oral health condition of most of the children were poor.

“…It became a topic of concern at the end of the 20 th century, also becoming of interest to clinical dental practice and dental public health [1,2]. Epidemiological surveys in various countries showed a high prevalence of dental erosion in children [2,3].…”

“…An increased prevalence of dental erosion was also seen in the UK between 2000 and 2002, increasing by 45% in 2000 and 2001 and by 60% in 2002 [2]. Dental erosion is defined as the condition of tooth surface loss or enamel demineralization caused by chemical processes that do not involve bacterial activity [1,7]. Early symptoms of tooth erosion are characterized by white spots on the enamel surface that are round, smooth, and shiny under a microscope, and subsequently dissolve enamel layer by layer [7,8].…”

Abstract. This study assesses the dental erosion status of 12-year-old Indonesian children and studies the determinants of dental erosion of these children. The survey was performed in 2016 with ethics approval. A multistage cluster proportional to size random sampling method was adopted to select 12-year-old children in 24 primary schools in Jakarta. The parents were asked to complete a self-administered questionnaire concerning their children's diet and oral health habits. The children were examined by a single calibrated examiner. Detection of dental erosion followed basic erosive wear examination (BEWE) criteria. A total of 487 children participated in the survey. Most children (88%) had at least some signs of erosion (BEWE > 0), with dentin being involved in 50% of the cases (BEWE = 2). Dental erosion was significantly related to gender, the frequencies of citric tea consumption, parent's dental knowledge, father's education, and dental caries (OR = 3.148). The 12-year-old Indonesian school children who lived in Jakarta had signs of erosion, although severe erosion was not found. Screening programs should be provided to identify risk groups so early preventive measures can be taken.

“…Although many reports worldwide agree that the presence of dental caries had declined in the population [3], there are also, recent published studies presenting an alarming increase in the presentation of caries [4] [5]. These controversial results produced by a unique and well established methodology of measuring and rating caries among subjects, provoke and encourage epidemiologists in the field of oral health and public oral health to re-visit the DMFT index which was established more than 75 years ago.…”

Background: The well-established DMFT index has been used for over 75 years as a key for measuring dental caries in dentistry. DMFT is applied to permanent dentition and expressed as the total number of teeth decayed (D), missing (M), or filled (F), tooth (T) in an individual. Objectives: The objective of this study is to build a mathematical model for the existing DMFT index and compare its parameters by suggested new mathematical model. Mathematical Models: Fixed Model: Is a mathematical model for the existing DMFT index and will be considered as fixed model; in which all individuals under screening will have the same probability θ, 0 ≤ θ ≤1 of dental caries. In this fixed model the unit of the screening is the individual, and will be evaluated for caries as a dichotomous (0, 1) variable. Random Model: The new suggested model is a random model that suggests a mouth of an individual as an environment and the tooth is a unit of research. In this random model, only the teeth in one mouth have the same probability θ, 0 ≤ θi ≤ 1 where 1, 2, , i k =  ; number of screening individuals. Expected Outcome: Mathematically, the fixed model will highlight what the value 1 will hide as information and hence this may explain why the average of DMFT is may be overestimated for any sample studied using fixed model. The random model will yield a cumulative weighed probability on the function of the number of teeth screened per mouth θ, 0 ≤ θ ≤ 1, hence the average DMFT index will be weighed against the number of teeth screened per all subjects. Conclusion: The random model yields an average and more realistic expected value for the population studied. Furthermore, in such model, it is easy to estimate the variance and it is obvious that this model yields the smallest variance.
