Paedo Exam

It is important to look at the occlusion in every patient but especially in child patients as early diagnosis of occlusal anatomy will allow timely orthodontic intervention.
Note:
-Overbite: normally 3-4mm or 30% but look for openbites, deep bites, incomplete overbites (where there is overlap but anterior teeth don't contact). Class 2 often has a deep overbite
-Overjet: normally 2-2mm. Increase may suggest thumbsucking. OJ may be indicative of angles class. Edge to edge or crossbite in class 3, reduced in class 2 div 1, increased in class 2 div 2.
- Angles class
-Crossbites: anterior, posterior lingual crossbite or buccal crossbite (scissor bite)
-Excessive wear-> interferences
-Presence of canine bulge
-Missing teeth/Later eruption of permanent teeth/exfoliation of deciduous teeth
