If you thought the dentists in Oregon are scared of a ballot issue that would permit people other than dentists to fit and install false teeth, consider the doctors in North Dakota.

There, voters will decide Tuesday whether to pass an initiative that could allow the state to set maximum rates for all kinds of health services - those of doctors, dentists, hospitals, nursing homes, opticians, chiropractors, nurses and physical therapists - as well as prescription drugs.

Not surprisingly, the state's medical, dental and hospital associations are denouncing the measure as unclean, ungodly and worse yet, socialized medicine. And the proponents, the Teamsters Union and the Farmers Union, claim it will do for health care costs what California's Proposition 13 did for property taxes.

The Oregon and North Dakota measures are just two of about 200 ballot issues that voters in at least 38 states will consider next week.

The issues offer a little something for everyone.

If you like duels, you'll love Mississippi. There, the question is whether to repeal a section of the state constitution that forbids duels.

Assuming the measure passes, it still won't make the state a haven for 20th century Aaron Burrs. The practice is also barred by statute.

In its effort to clean out obsolete sections of its 1890 constitution, Mississippi is also asking voters to repeal a mandate for segregated schools and one that discriminates against men by declaring that the state librarian must be a woman.

But a lost job opportunity in Mississippi may be one gained in Wyoming. If you're a woman there and you want to work in the mines, you can vote to repeal a state constitutional provision banning women from mines.

If you're a gambler, there are proposals to permit betting on jai alai in New Jersey, casino gambling in Miami Beach and partmutuel horse racing in Virginia and two Indiana counties. In Virginia the vote may be close but the proponents of gambling seem to be ahead by a length.

If you like drinking, try Oklahoma, where there's a measure to allow franchising of strong beer, or kansas, where Johnson and Wyandotte counties will vote on allowing liquor by the drink in certain restaurants, or Montana, where you can vote to allow the sale of wine in grocery and drug stores.

Then there's Michigan, which has a proposal to raise the drinking age from 19 to 21, and Heber City.Utah, where the whole town is bitterly divided over an issue that would outlaw beer sales on Sundays. Opponents have accused the Mormon proponents of "regligious demagoguery," and Gene Gardner, a Mormon supporter of the measure has argued. "I think we shoulde have our say. We're the majority."

If you thought homosexual rights are an issue only in California - where Proposition 6 would refuse teaching jobs to anyone who admitted being gay or advocated homesexually - don't overlook Seattle and Dade Country, Fla.

In Seattle the vote is expected to be close on an initiative to repeal ordinances barring discrimination against gays in housing and employment.

In Dade County, where singer Anita Bryant led a successful campaign last year that repealed a gay rights ordinance, voters this time are being asked to approve a measure undoing the 1977 action. But this one is broader - it would ban discrimination not only on the basis of sexual preference but also race, religion, marital or military status, source of income and state of pregnancy.

This time the public seems apathetic and Bryant is keeping a low profile. Bob Green, her husband and manager says he's tired of the issue adding, "This is an aggravation we don't need again."

Equal rights for women in an issue in two states, neither of which is among the 35 that have ratified the proposed Equal rights Amendment to the U.S. Constitution that would outlaw state and federal sex discrimination.

In Nevada, where the legislature has rejected the ERA three times, there is non-binding advisory measure that if approved would recommend ratification. In Florida, voters will consider a proposal to expand the state's bill of rights to ban sex discrimination.

Several states are giving their voters a chance to get tough on crime. California has an initiative to expand the categories of first degree murder for which the death penalty may be imposed. The measure, which seems sure to pass, would add such things as driving a getaway car while not actually committing the murder to the list of capital offenses.

Oregon, which abolished its death Penalty for murder in 1964, now has a ballot measure asking voters if they want to reinstate it.

Michigan has a measure that would deny bail to persons accused to armed robbery, rape or kidnaping or of any other violent crime if he or she is a repeat offender. Now bail can be denied only in cases of murder and treason.

South Dakota has an anti-obscenity measure that is a prosecutor's dream. It would outlaw all sorts of "objectionable" things and forbid a defendant from pleading guilty, thus forcing the material at issue to be judged as to its obscenity by a jury.

Any defendant found guilty would have to pay all investigation prosecution and court unless he or she wanted to plead guilty and in no way aided the defense. Supporters say the measure would deter smut peddlers; opponents say it may be unconstitutional as well as too stringent since there are only two adult bookstores and three adult movie houses in the whole state.

The nuclear issue has shifted to Montana, where voters will decide whether to impose the most rigid re it could provide safe storage of radio-active waste for future generations.

So far, however, no one has proposed building a nuclear plant in Montana.

School busing is an issue in the state of Washington, where there is a move to ban it except to the school nearest or next nearest a student's home. The measure is aimed at nullifying Seattle's plan, which went into effect this fall.

The city is the first larget community to implement a mandatory busing plan without a court order, and so far busing has worked without major hitches or controversies. Some polls say the measure will carry by a small margin.
