Intraoral symptoms presented by patients with systemic disease may not be originated simply from their teeth and periodontal tissue. Because the specific systemic disease could be expressed in oral cavity, thorough inspection, differential diagnosis and appropriate dental treatment must be required. Authors report two cases of dental patients with systemic disease in department of advanced general dentistry. For accurate diagnosis, proper treatment and appropriate medical consultation, it is impossible for general dentist to emphasize importance of medical history taking too much.

Impaction of tooth is a situation in which an unerupted tooth is wedged against another tooth or teeth or otherwise located so that it cannot erupt normally. The supernumerary tooth is also called as hyperdontia and defined as the condition of having additional tooth to the regular number of teeth. The most common supernumerary tooth is a mesiodens, which is a mal-formed, peg-like tooth that occurs between the maxillary incisors. The supernumerary tooth is commonly impacted but they are frequently impacted on maxilla. Ectopic impaction of supernumerary tooth on mandibular condyle, coronoid process, ascending ramus, and pterygomandibular space is very rare condition. In this case, we report a case of impacted supernumerary tooth on mandibular sigmoid notch without definite pathologic change.

본 연구는 거대 편도를 가진 기능성 III급 부정 교합자의 구대 편도 절제술 전후의 인두강, 설골, 두부 위치의 변화 양상에 대해 알아보기 위해 단국 대학교 부속 치과 병원 교정과에 내원한 남녀 환자 42명을 대상으로 연구하여 다음과 같은 결론을 얻었다. 1. Enlarged tonsil을 보이는 기능성 3급 부정교합자는 1급 부정교합자보다 혀는 전방에 위치하고 설골은 하방에 위치한다. 2. Tonsillectomy 후에 편도 절제술전과 비교하여 혀는 후방에 위치하고, nasopharynx은 증가 양상을 보이며, 설골은상, 후방에 위치하며 counterclockwise rotation 양상을 보인다. 3. Tonsillectomy 후에 nasopharynx depth변화와 하악 전치 경사도, 혀의 수직적 변화와 cranial base에 대한 hyoid axis, hyoid의 수직적, 수평적 변화와 두경부 경사도, 두경부 경사도와 하악 전치간에 95% 유의수준으로 상관성을 보인다. 4. Tonsillectomy 후에 설골 장축의 counterclockwise rotation시 hya-NL의 감소와 nasopharyx의 증가를 보이고, 혀의 거상시 hya-NL의 감소를 보이며, 혀의 후방위치시 h-h1의 증가와 hya-ba-n의 감소를 보인다. This study was carried out in order to find out the changes of the pharyngeal airway, hyoid bone and head posture before and after tonsillectomy in functional class III malocclusion patients. For this study, 21 Angle's class I patients and 21 Angle's class III patients, totally 42 subjects were chosen. The results were as follows; 1. In comparison to Class I group, tongue was more anteriorly and hyoid bone was more inferiorly positioned in functional Class III group 2. In comparison to pre-tonsillectomy, tongue was more posteriorly positioned and larger nasopharynx depth was shown in post-tonsillectomy. In post tonsillectomy, the hyoid bone was displaced posteriorly and superiorly and counterclockwise rotation was shown. 3. The level of significance for the correlation shown was 5 percent (p<0.05) indicating that: The change of nasopharyx depth was correlated to the inclination of lower incisors. Vertical change of tongue posture was correlated to the hyoid axis change. Vertical change of hyoid bone was correlated to the horizontal change of hyoid bone, craruocervical inclination. The change of craniocervical inclination was correlated to the inclination of lower incisors. 4. After the tonsillectomy, counterclockwise rotation of hyoid axis was associated with decease of hya-NL and large nasopharyngeal airway. High posture of the tongue was associated with decrease of hya-NL. Posterior posture of the tongue was associated with increase of h-hl,and decrease of hya-ba-n.
