A number of differences were found. For example, the condylar fossa was located significantly (P C 0.001) more anterior in the skull relative to cranial base. Also, there were severalmale/femaledifferencesin the prognathicgroup, such as the ratio of ramus to body length (P < 0.01). In addition, the rate of growth deviation could be assessed from the growth charts, permitting an estimateof future growth for prognosticpurposes. Force Distribution Characteristics

Activation of the basic utility arch wire with tip-back and distal molar rotation bends generatedstressesof varying intensity on the lateral and central incisors. Stresseswere concentratedat the lingual apical regions of theseteeth, indicating the effect of intrusive lingual root movement. Lower-level stresseswere observed in the mesial and apical regionsof the first molars. The labial root torque placedin the anteriorsegmentof the wire was observedto negatethe lingual root movement,thus creatinga more effective intrusion response.The expansionutility arch created the effect of labial root movement of the incisors, whereasthe contraction arch wire producedthe opposite reaction. Orthodontic Force Production by Open Coil Springs K. L. Harvey, A. A. Caputo, and S. J. Chaconas J. Dent. Res. 56: B191. June, 1977
Force-productioncurveswere found to be linear for a portion of the loading continuum characteristicof each alloy type. For each spring, force production was found to increase with increasingwire size and decreasinglumen size. Arch-wire type had little effect upon the slope of the load-compressioncurves but did effect, in a variable manner, the maximum load attained.A table generatedfrom test curvesprovidesthe clinician with a guide to proper spring selectionand activation length for a desiredamountof orthodonticforce. The Mouth of the Alcoholic P. Laudenbach and J. Laufer Actual. Odontostomatol., No. 115, September, 1976
The odontologic and stomatologiceffects of alcoholism are ethylic impairment of the salivary glands and the ravagesof caries and alveolosis; alchohol is responsiblefor more than a third of maxillofacial trauma. It is, statistically, the main factor of 80 per cent of cancer of the buccal cavity. It can also be attributed to pathogenesisof cervicofacial adenolipomatosisand rhinophyma. A Comparative Evaluation of the Scrub and Bass Methods of Toothbrushing With Flossing as an Adjunct (in Fifth and Sixth Graders) E. Robinson Am. J. Public Health 63: 1078-1081, 1976
The scrub and bassmethodsof toothbrushingwith flossing as an adjunct were evaluated to determinewhich is most effective in eliminating or reducingplaque and gingivitis in fifth- and sixth-gradeschoolchildren. Three hundred eleven children were randomly
