口腔常识的误区及正确指导.pptVIP

少年时期11~15岁 专家指出一般的牙性畸形，恒牙列早期(即十二三岁)是最佳牙齿矫正的时机，因为这时儿童刚换完牙，并且处于生长发育比较旺盛的时候。正畸医生把这段年龄称为“黄金时期”。 一般来说，临床儿童常见的颌面畸形可分为两类：牙性畸形和骨性畸形。由于骨性畸形可发展导致颜面部畸形，因此骨性畸形的矫正，应在儿童处于生长发育高峰前期进行矫治(女孩10-12岁，男孩11-13岁)。 特殊情况特殊对待 一种情况例外，那就是前牙反咬牙合(俗称“地包天”)。这种畸形对儿童的颌骨发育有比较严重的影响，一旦发生应立即矫正，最早矫正可以开始于3岁半左右。通常只需要3-6个月的时间，就可以将反咬在下颌牙齿内侧的乳上前牙推移出来。  孕前期20~30岁 孕前期口腔检查容易被大家忽视，而孕妇怀孕后发生口腔疾病，会出现治疗风险高、难度大的问题。妇女在怀孕前就应做好口腔检查与保健，发现问题应及时治疗，为整个孕期与哺乳期排除口腔隐患。 两大原因使孕妇易患口腔疾病：一是因为孕妇怀孕后体内的激素水平增高，而牙龈细胞中含特异性的雌激素和睾丸素受体，牙龈就成为一些性激素的靶器官。所以孕妇易患妊娠性牙龈炎、妊娠性牙龈瘤和牙体牙髓病等口腔疾病。 　　另一个重要原因是孕妇缺钙。这是因为胎儿及母乳的钙来源于母亲，孕产妇在大量钙流失的情况下，牙齿更容易受菌斑及外界因素的影响而患牙病，会出现多个牙齿的龋坏，甚至发展成牙髓炎或根尖炎，影响孕妇及胎儿的营养摄入，给自身和胎儿都造成不良影响。 孕妇在怀孕前3个月及后3个月都不宜实施口腔手术。前3个月容易引起流产，后3个月容易引起早产。因此，孕前检查及口腔保健就显得格外重要。女性在准备怀孕前，应到正规口腔医院做一下全面的口腔检查，全面了解牙齿情况。 健美牙齿 灿烂人生 Thank you!
