Abstract:
BACKGROUND: Kissing molars (KMs) is defined as a state in which the apex of two impacted molars face opposite directions and the occlusal surfaces touch each other and the crown is in one follicle. Class III KMs have been reported previously; however, reports on class III KMs in young people (< 18 years of age) are limited.
METHODS: Here, we present the case of KMs class III confirmed at an early age, supported by a review of the literature. The patient was a 16-year-old female and experienced discomfort in the left molar of the lower jaw and visited in our department. We diagnosed KMs based on an impacted teeth on the buccal side, near the lower jaw wisdom teeth, and a cyst-like low-density area observed around the crown of both teeth, as revealed by computed tomography. We decide to extract the tooth and enucleate the cyst under local anesthesia as the patient experienced discomfort due to occlusion. Furthermore, the cyst-like structure removal and tooth extraction including tooth root were necessary as the patient had KM class III, possibly inducing complicated malocclusion. Although no previous reports recommended timing for KMs tooth extraction, we propose that extraction at an early stage is important regardless of age especially in class III cases.
CONCLUSIONS: We report a case of KM class III detected at an early age.
摘要:
背景:接吻磨牙(KM)被定义为这样一种状态,其中两个阻生磨牙的顶点朝向相反的方向,并且咬合面彼此接触,并且牙冠在一个毛囊中。以前曾报道过III级KM;然而,关于青少年(<18岁)的III类KMs的报告有限。
方法:这里,我们介绍了早期确诊的KMsIII级病例,在文献综述的支持下。患者是一名16岁的女性,下颌左磨牙不适,并在我们部门就诊。我们根据颊侧受累的牙齿诊断了KMs,靠近下颌智齿,在两颗牙齿的牙冠周围观察到囊肿状的低密度区域,计算机断层扫描显示。我们决定拔除牙齿并在局部麻醉下摘除囊肿,因为患者因咬合而感到不适。此外,由于患者患有III级KM,因此需要切除囊肿样结构和拔牙,包括牙根,可能诱发复杂的错牙合畸形.尽管以前没有报告推荐KMs拔牙的时机,我们认为,无论年龄如何,早期提取都很重要,尤其是在III类病例中。
结论:我们报告了一例早期发现的III级KM。
