According.to.the.National.Health.and.Nutrition.Examination.
Survey. (NHANES),. there. were. approximately. 86. million. participants.
that. reported. ever. using. marijuana.. Marijuana. users. are.
known.to.develop.dry.mouth.and.to.eat.snacks.after.smoking..This.
study.examines.the.association.between.marijuana.use.and.active.
caries,.considering.demographic.and.behavioral.characteristics,.in.
a.national.probability.sample..This.cross-sectional.analysis.utilizes.
NHANES. 2005-2006. data.. The. study. sample. represents. a. total.
weighted.population.of.146.million.adults.ages.20.to.59..The.dependent.variable.is.the.presence.or.absence.of.active.decay..Marijuana.
use.is.the.independent.variable,.with.sociodemographic.variables.
as.covariates..Using.a.multivariate.logistic.regression.analysis.with.
complex.survey.design,.the.weighted.results.indicate.that.marijuana.
is.a.significant.factor.when.demographic.and.behavioral.variables.
are. included.. Furthermore,. marijuana. users. are. 34%. more. likely.
to.have.caries.present.than.non-users..Females.are.26%.less.likely.
than.males.to.have.active.caries..Those.with.the.lowest.education.
(less.than.9 th .grade).were.almost.6.times.more.likely.as.those.with.
the.highest.education.(above.college);.obese.people.are.36%.more.

Low.levels.of.Vitamin.D.are.associated.with.substantial.cognitive.decline.in.the.elderly.using.MMSE..To.date,.no.study.has.evaluated.cognitive.decline.in.Vitamin.D.deficient.patients.attending.a.
multidisciplinary.medical.clinic.utilizing.ERP.P300.measurements..
80. patients. having. varied. clinical. diagnoses. were. assessed.
(mean. age=53.99;. [19.5y,. 79.7y]).. They. were. 58.75%. female.
and. 41.25%. male.. We. compared. serum. 25(OH)D. deficient. (25.
nmol/L)..
Patients.with.Vitamin.D.deficiency.had.average.P300.latency.
and.voltage.of.335.52ms.and.4.720microV,.respectively;.the.normal.Vitamin.D.group.had.average.P300.results.of.327.71ms.and.
5.36microV,.respectively..The.average.PTH.levels.were.36.11pg/
mL.and.45.52.pg/mL,.for.the.Vitamin.D.deficient.and.normal.group,.
respectively.
ANOVA.of.gender.and.Vitamin.D.levels.was.not.significant.
for.P300.latency,.but.the.interaction.term,.gender.x.Vitamin.D.level,.
in.the.ANOVA.for.P300.voltage.was.significant.(F=4.40,.p=.039)..
Examination. of. the. means. showed. that. for. males,. P300. voltage.
was.significantly.greater.(t=-2.33,.p=.027).in.the.normal.(5.83).vs.
low.(3.39).Vitamin.D.groups..Although.the.overall.model.for.PTH.
was.not.significant,.examination.of.the.means.showed.a.trend.for.
females,.such.that.PTH.was.significantly.greater.(t=-2.33,.p=.024).
in.the.normal.(45.40).vs.low.(32.19).Vitamin.D.groups..
Our.data.concurs.with.reports.suggesting.Vitamin.D.deficiency.
