T he effects of liquid protein diet (LPD) on gingival collagen metabolism were evaluated in young rats. Experimental animals received a LPD, while pair‐fed and ad libitum groups received a 20% casein diet. Prior to sacrifice at days 23, 35 and 48 post‐partum, animals from each group were injected with C 14 ‐proline. Gingival tissues from the palate were excised and analyzed for collagen content and collagen synthesis. Results of body‐weight changes at day 48 showed a 20% decrease in the LPD group, while pair‐fed and ad libitum groups increased 47% and 267%, respectively. Collagen content per gram of gingiva was not significantly different among the three groups. Gingival collagen synthesis, however, did show significant differences among the three groups. It was concluded that while LPD effects on the overall body condition were profound, LPD exerts minimal effect on gingival collagen metabolism in young rats.
