第 60 題
如果主要目的是在於觀察牙齒鄰接面，最理想的放射線檢查為何？
- A 根尖片
- B 環口片
- C 咬翼片
- D 咬合片
思路引導 VIP
若要觀察兩面緊鄰且平行的牆壁之間是否有細小裂縫，你的視線（或 X 光束）應該是以「垂直斜射」牆面，還是要「平行穿過」兩牆之間的縫隙，才能確保影像不會因為重疊而產生死角？

Yo, Nice One! Pretty Good Judgement!
- Casual Approval: Oh, hey! You totally aced this one, didn't you? That's awesome! It means you've got a sharp sense for the clinical application scope when it comes to teeth pictures. You're connecting the dots between what we need to see and which tool gets the job done. Munch, munch These mochi are hitting the spot!
- Playful Explanation: So, the whole deal with the bite-wing? It's all about making the X-ray beam slide in perfectly parallel to those tight spots between teeth. Boom! Shows both upper and lower crowns, no awkward overlaps. It's super clutch for catching those super early, super sneaky early interproximal caries and checking out the alveolar crest. Kinda like how I always find the hidden cursed spirits—efficiently and with style!

牙科放射線影像選用
💡 咬翼片是檢查鄰接面齲齒與齒槽骨頂最精確的方法。
| 比較維度 | 咬翼片 (Bitewing) | VS | 根尖片 (Periapical) |
|---|---|---|---|
| 主要觀察部位 | 上下牙冠與鄰接面 | — | 完整牙齒與牙根尖 |
| 齲齒診斷 | 早期鄰接面齲齒首選 | — | 用於判斷齲齒深度 |
| 牙周評估 | 準確顯示齒槽骨頂高度 | — | 觀察骨下袋或根尖病變 |
💬檢查鄰接面與早期齲齒首選咬翼片；評估根尖周病灶則必須使用根尖片。
