Are oral health and fixed orthodontic appliances associated with sports injuries and postural stability in elite junior male soccer players?

Table 2 Injury Frequency in the Past Year (IFPY) by Oral Status

Number of sport injuries past year	Oral Status
Number of sport injuries past year	Both GP/DC and FOA absent N (%), ASR	Current or past FOA N (%), ASR	GP/DC present FOA absent, N (%), ASR
0	20 (42%) + 1.9	26 (35%) + 0.9	12 (19%) - 2.6
1.	13 (27%) - 0.3	20 (27%) - 0.5	21 (33%) + 0.9
2–3	13 (27%) - 0.8	17 (23%) - 2.1	29 (45%) + 2.9
4 or more	2 (4%) - 1.3	12 (16%) + 3.0	2 (3%) - 1.9

ASR Adjusted Standardized Residual (|ASR| > 1,96 indicates cell with observed frequency significant different from the expected frequency); GP/DC Gum problems and/or dental caries; FOA Fixed Orthodontic Appliance; IFPY is significantly associated with oral status (χ²(6 df) = 19.9, p < .005)
