Summary

<span style="font-family: TribuneItalic; font-size: 9pt; color: #000000; font-style: normal; font-variant: normal;"><em>The growth and development play an important role in orthodontics mainly in bone, because it can determine the maturity of the </em><span style="font-family: TribuneItalic; font-size: 9pt; color: #000000; font-style: normal; font-variant: normal;"><em>bone. Bone maturity evaluation is very important in orthodontic treatment, because there are many individual variations in growth </em><span style="font-family: TribuneItalic; font-size: 9pt; color: #000000; font-style: normal; font-variant: normal;"><em>and development such as time, duration and velocity of the growth. Nutritional status during pregnancy and infant period will </em><span style="font-family: TribuneItalic; font-size: 9pt; color: #000000; font-style: normal; font-variant: normal;"><em>influence the growth and the development of bone. Protein diet is an important factor, which will determine the optimal calcification </em><span style="font-family: TribuneItalic; font-size: 9pt; color: #000000; font-style: normal; font-variant: normal;"><em>during bone growth and development stages. Bone calcification, in orthodontics, can be used to estimate the bone maturity for </em><span style="font-family: TribuneItalic; font-size: 9pt; color: #000000; font-style: normal; font-variant: normal;"><em>diagnosis and treatment planning. The purpose of this study was to recognize ones ability to surpass calcium and phosphor deficiency </em><span style="font-family: TribuneItalic; font-size: 9pt; color: #000000; font-style: normal; font-variant: normal;"><em>because of pre and postnatal protein deficiency. There were three groups of samples of Rattus norvegicus rats. The first group was </em><span style="font-family: TribuneItalic; font-size: 9pt; color: #000000; font-style: normal; font-variant: normal;"><em>the control group with standard diet, the second was the infant group with pre and postnatal protein deficiency, and the third group </em><span style="font-family: TribuneItalic; font-size: 9pt; color: #000000; font-style: normal; font-variant: normal;"><em>was young rat at weaning age with pre and postnatal protein deficiency supplemented with enough protein in the diet. Bone </em><span style="font-family: TribuneItalic; font-size: 9pt; color: #000000; font-style: normal; font-variant: normal;"><em>calcification stage was analyzed: 1) Histologically by measuring epiphyseal width on right femur; 2) by measuring calcium and </em><span style="font-family: TribuneItalic; font-size: 9pt; color: #000000; font-style: normal; font-variant: normal;"><em>phosphor concentration on left femur with Spectrophotometry Atomic Absorption and spectroscopy ultra light visible. The data </em><span style="font-family: TribuneItalic; font-size: 9pt; color: #000000; font-style: normal; font-variant: normal;"><em>were analyzed by one way ANOVA continued by t test. The result showed that: 1) there was significant (p < 0.01) epiphyseal width </em><span style="font-family: TribuneItalic; font-size: 9pt; color: #000000; font-style: normal; font-variant: normal;"><em>difference between group I and II, I and III (p < 0,01) but there was not significant difference between group II & III (p > 0.05); 2) </em><span style="font-family: TribuneItalic; font-size: 9pt; color: #000000; font-style: normal; font-variant: normal;"><em>there was significant calcium and phosphor concentration on bone between group I, II and III (p < 0.01). It was concluded that bone </em><span style="font-family: TribuneItalic; font-size: 9pt; color: #000000; font-style: normal; font-variant: normal;"><em>calcification damage because of pre and post natal protein deficiency was an irreversible process. Protein supplement after bone </em><span style="font-family: TribuneItalic; font-size: 9pt; color: #000000; font-style: normal; font-variant: normal;"><em>calcification could not restore the condition.</em></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span><br style="font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: -webkit-auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px;" /></span>
