2.2 Data Collection
Demographic (age, gender, and parental education status), Early Childhood Oral Health Impact Scale (ECOHIS) and QoL data were evaluated. The dentition period and dental occlusion status were determined by an intraoral examination, and the Decayed, Missing, and Filled Teeth (DMFT/dmft) index was applied along with the Simplified Oral Hygiene Index (SOHI).
2.3 SOHI: Six teeth, considered representative of all anterior and posterior teeth, were evaluated (numbers 16, 26, 11, 31, 36, and 46). The facial surfaces of teeth 16, 26, 11, and 31, and the lingual surfaces of teeth 36–46, were also evaluated. After obtaining debris and calculus scores on a 4-point (0–3) scale, the SOHI was administered.
2.4 DMFT index: The decayed, filled, and lost teeth of the participants were identified, and the data were recorded based on the DMFT/dmft scale (DT: decayed teeth, MT: lost teeth, FT: filled teeth, dt: decayed primary teeth, mt: lost primary teeth, ft: filled primary teeth).
2.5 ECOHIS-T: This scale consists of 13 questions answered using 4-point Likert scales (14). The data were recorded by a single pedodontist. The first nine and final four questions comprise the child impact scale (CIS) and family impact scale (FIS), respectively. The CIS covers four domains and the FIS two domains. The CIS includes one question on symptoms, four on function, two on psychological processes, one on self-perception, and one on social communication. The FIS consists of two questions each on parental distress and family function. Each question is scored between 0 and 5; total scores therefore range between 0 and 52 (0–36 CIS and 0–16 for FIS) (15).
