Determination and provision of basic knowledge and skills level Basic level control tests Test 1 Patient is 30 year-old. The oral cavity examination determined that dental formula is in accordance to age, but the frenulum of the upper lip is short, thick, intertwining with the gingival papilla. There is the 4 mm diastema on the maxilla. The mesiobuccal cusp of the first permanent molar of the maxilla occludes with the buccal groove of the first molar of the mandibular. The sum of the width of 12, 11, 21, and 22 is 27 mm. What factor causes the diastema? 1. Macrodentia. 2. Abnormality of the frenulum of the upper lip. 3. Macroglossia. 4. Adentia. 5. Harmful habits.
Test 2 19 year-old man. Intraoral examination revealed that the dental formula is in accordance to the patient age. There is an absence of contact of the upper and lower incisors and absence of the vertical overlap. The space between incisor edges of the upper incisors to the lower incisors is 4 mm in vertical plane. The patient has mouth breathing and infantile swallowing. He has got a biting habit (pencil biting). What kind of malocclusion is there? 1. Anterior open bite. 2. Deep bite. 3. Anterior crossbite. 4. Mesial occlusion. 5. Distal occlusion.
Test 3 21 year-old woman. Intraoral examination revealed that the dental formula is in accordance to the patient age. There is the vertical space of 6 mm between the upper and lower incisors. The patient has nasal breathing; there are tension of the lips and tongue thrusting from the upper lip during swallowing. What is the abnormal function of the maxillofacial system in this case? 1. Breathing through the mouth. 2. Infantile swallowing. 3. Mature swallowing. 4. Lazy chewing. 5. Harmful habit of cheek sucking.
Test 4 20 year-old man. The oral cavity examination determined the dental formula is in accordance to age. The overbite is 1/3 of the lower incisors. The mandibular incisors contact with the palatal surfaces of maxillary incisors. The midlines of both arches coincide. The mesiobuccal cusp of the maxillary first permanent molar occludes with buccal groove of the mandibular first molar. What occlusion is this? 1. Bimaxillary protrusion. 2. Crossbite. 3. Orthogenic occlusion. 4. Orthognathic occlusion. 5. Distal occlusion.
Test 5 32 year-old man. Extra-oral examination revealed that the proportion of the face is disturbed because of the lengthening of the lower face height. Intra-orally: there is the vertical space of 5 mm between upper and lower incisors. The patient has nasal breathing; there are tension of the lips and tongue thrusting from the upper lip during swallowing. What is the abnormal function of the maxillofacial system in this case? 1. Breathing through the mouth. 2. Infantile swallowing. 3. Mature swallowing. 4. Lazy chewing. 5. Harmful habit of cheek sucking. KEYS
