| Kanazawa et al. [47] | 2019 | 70 (intervention: n = 35, control: n = 35) | Mean (s.d.) = 74.8 (8.0) in the intervention group and 78.6 (6.8) in the control group | RCT | 6 months | Intervention group: maxillary and mandibular CD fabrication and dietary advice | Dietary intake estimated by BDHQ | Higher dietary intakes of several nutrients including protein (ANCOVA, mean = 100.2 g in intervention group vs. 93.3 g in control group, p < 0.01) were seen in the intervention group at 3 months post-intervention, but not at 6 months post-intervention. |

| Nabeshima et al. [50] | 2018 | 32 | Mean (s.d.) = 73.2 (7.7) | Non-RCT | 3 months | PD placement and dietary counseling | Dietary intake estimated by BDHQ | Dietary intake of vegetables (linear mixed model, effect size between post-intervention and baseline = 74 g), α- (70 μg) and β-carotenes (1036 μg), and dietary fiber (2.5 g) increased at follow-up evaluation 3 months after the PD placement. Serum concentration of carotenoids and vitamin C remained consistent. |

| Suzuki et al. [48] | 2018 | 62 (intervention: n = 31, control: n = 35) | Mean (s.d.) = 75.3 (8.2) in intervention group and 78.6 (6.6) in control group | RCT | 3 months | Intervention group: maxillary and mandibular CD fabrication and dietary advice | Dietary intake estimated by BDHQ | Higher dietary intakes of several nutrients, including protein (ANCOVA, mean = 101.6 g in intervention group vs. 93.5 g in control group, p < 0.01), were seen in the intervention group at 3 months postintervention. |

| Suzuki et al. [49] | 2019 | 59 (intervention: n = 30, control: n = 29) | Mean (s.d.) = 74.8 (8.0) in intervention group and 78.6 (6.8) in control group | RCT | 6 months | Intervention group: CD fabrication and dietary advice | MNA-SF | Higher MNA-SF score (Mann–Whitney U test, median [IQR] = 13 [13,14] in intervention group vs. 13 [[11], [12], [13]] in control group, p < 0.01) was seen in the intervention group at 6 months postintervention. |

ANCOVA = one-way analysis of covariance, BDHQ = brief-type self-administered diet history questionnaire, CD = complete denture, PD = partial denture.
