PORTLAND — Mainers have given their approval to two bond issues totaling nearly $15 million.

With 28 percent of the precincts reporting, voters on Tuesday were favoring a $5 million bond package aimed at improving dental care by a margin of 57 percent to 43 percent. Of the total, $3.5 million will be awarded to a Maine university or college to assist in the creation of a teaching clinic, a major step toward the formation of Maine’s first dental school.

The other bond question, which sought nearly $10 million to acquire conservation lands, was being favored by a 64-36 margin.

Half a million dollars will go to the Department of Conservation to preserve state parks and properties it manages. The remainder will be distributed by the Land for Maine’s Future Board.
