Supernumerary teeth are often asymptomatic and impacted within the jawbone, typically identified during routine radiographic examinations. While cases of impacted fourth molars have been reported, bilaterally erupted fourth molars are exceedingly rare. This case report presents a unique instance of symmetrically erupted maxillary fourth molars, along with an impacted fifth molar in the right upper jaw. A 38-year-old male presented with food impaction and discomfort in the area of the left maxillary third molar. Clinical examination revealed bilaterally erupted fourth molars, and a panoramic radiograph incidentally uncovered an impacted fifth molar in the right maxilla. Cone beam computed tomography confirmed these findings. The left maxillary fourth molar was diagnosed with periapical periodontitis. Both the left maxillary third and fourth molars were extracted under local anesthesia. Periodic follow-up of the right fourth and fifth molars was recommended based on symptom progression and patient preference. The patient expressed satisfaction with the treatment plan and surgical outcome. This report documents a rare case of symmetrically erupted fourth molars with an associated impacted fifth molar in the maxilla. The treatment strategy and surgical approach should be tailored to the patient's symptoms and willingness to undergo the recommended procedures.
多生牙通常无症状且埋伏于颌骨内，一般在常规影像学检查时被发现。虽然有报道称存在埋伏的第四磨牙病例，但双侧萌出的第四磨牙极为罕见。本病例报告呈现了一例上颌第四磨牙对称萌出且右上颌有一颗埋伏第五磨牙的独特病例。一名38岁男性因左上颌第三磨牙区域食物嵌塞和不适前来就诊。临床检查发现双侧第四磨牙已萌出，全景X线片偶然发现右上颌有一颗埋伏的第五磨牙。锥形束计算机断层扫描证实了这些发现。左上颌第四磨牙被诊断为根尖周炎。在局部麻醉下拔除了左上颌第三和第四磨牙。根据症状进展和患者意愿，建议对右侧第四和第五磨牙进行定期随访。患者对治疗方案和手术结果表示满意。本报告记录了一例上颌第四磨牙对称萌出并伴有一颗埋伏第五磨牙的罕见病例。治疗策略和手术方法应根据患者症状和接受推荐治疗的意愿进行调整。
