## Case: Vertical Fracture Diagnosis ### Question Have a look at this maxillary occlusal radiograph. Then, look at the periapical view of the same patient. What can you see, and why is the occlusal view important here? ### Findings and Reasoning * **Observations:** The maxillary occlusal radiograph clearly shows a vertical fracture running down the 2.1 from the crown onto the root surface. * **Comparison:** In the periapical view, the horizontal crown fracture is obvious (the tooth structure is missing) , but the vertical fracture is almost impossible to see. Even taking another periapical at a different angle only shows it slightly. * **Reasoning:** Radiographs are two-dimensional. Because of the specific angulation (roughly 65 degrees), a maxillary occlusal radiograph provides the best chance of capturing the true extent of fractures that a single periapical might miss. ## Case: Incidental Finding on Occlusal Radiograph ### Question Have a look at this maxillary occlusal radiograph (taken with a size 2 film). Has anyone noticed anything slightly unusual? ### Findings and Reasoning * **Observations:** There is a **mesiodens** present. * **Reasoning:** A mesiodens is a supernumerary tooth that is typically conical, inverted, and found near the midline of the maxillary arch (usually slightly off-center). This case demonstrates how much more information can be gained from an occlusal radiograph, as this was an incidental finding not necessarily related to the trauma. ## Case: Suspected Abuse (Non-Accidental Injury) ### Question Consider this case of a child who presented for a routine examination. What "red flags" should a clinician look for during a trauma assessment? ### Findings and Reasoning * **Observations:** The child had a pattern of bruising on the arm and face. Following a history, it was found the child had been beaten with a belt. * **Reasoning:** If you see bruises around the face or arms that are not consistent with the history provided or the reported mechanism of dental trauma, these are red flags for non-accidental injury or child abuse. Meticulous documentation and photography are essential for these cases. ## Case: Spontaneous Re-eruption of Intruded Teeth ### Question Have a look at this case where the 5.1 and 6.1 are essentially 90% intruded. What is the management and expected outcome? ### Findings and Reasoning * **Observations:** The teeth are almost entirely driven into the socket. * **Outcome:** Six months later, the teeth have spontaneously re-erupted. * **Reasoning:** Approximately 80% of intruded primary teeth will re-erupt spontaneously without intervention. However, there is a one-in-three chance that complications (like infection or ankylosis) will arise, necessitating close monitoring for at least 12 months. ## Case: 100% Intrusion vs. Avulsion ### Question A child presents after a fall; the parents couldn't find the tooth and believe it was knocked out (avulsed) in the playground. How do you confirm the diagnosis? ### Findings and Reasoning * **Clinical Observation:** Looking closely at the photograph, there is a visible bulge around the gingiva. * **Radiographic Findings:** The radiograph shows the tooth has not been avulsed; it is 100% intruded into the alveolar bone and gingiva. * **Reasoning:** On an occlusal exposure, "foreshortening" of the intruded tooth usually indicates buccal displacement (away from the permanent tooth follicle). A lateral radiograph (though rarely taken) would show if the apex has been forced through the buccal plate. ## Case: Vertical Fracture Diagnosis ### Question Have a look at this maxillary occlusal radiograph.

How does the clinical presentation change the treatment approach? ### Findings and Reasoning * **Case A (Interference):** The teeth have been pushed so far back that there is a "step defect" and the child cannot bite properly (occlusal interference). There is very little chance these will heal with conservative management; extraction is often necessary. * **Case B (No Interference):** The tooth is luxated but does not interfere with the bite. A conservative approach (soft diet, monitoring) is appropriate here, as there is a good chance of healing. ## Case: Ankylosis Complication ### Question Look at this image of a primary tooth following trauma. What has happened to the surrounding bone? ### Findings and Reasoning * **Observations:** The tooth is ankylosed. There is now a significant alveolar defect where the bone has failed to grow normally in that area. * **Reasoning:** If a traumatized primary tooth becomes ankylosed and is not monitored or managed, it can result in significant disturbances to alveolar bone growth and prevent the permanent tooth from erupting appropriately. ## Case: Pulp Polyp ### Question A child presents with a growth coming out of a fractured tooth. What is this condition? ### Findings and Reasoning * **Observations:** There is proliferative tissue (a "pulp polyp") or hyperplasia of the pulp. * **Reasoning:** This was a case of a complicated crown fracture that was either not detected or not treated initially. The chronic exposure of the pulp led to the development of this polyp, requiring the tooth to be extracted. ## Case: Gingival Dehiscence ### Question Look at this case where a "flap" of tissue developed following trauma. What is revealed underneath? ### Findings and Reasoning * **Observations:** A proliferative flap of granulation tissue developed. When gently raised, it reveals exposed alveolar bone (dehiscence). * **Reasoning:** This is a gingival defect that occurs when healing is inadequate following a luxation injury. ## Case: Infra-occlusion and Discoloration ### Question A child presents with pain in an upper primary molar. Looking at the anterior teeth, what subtle signs of previous trauma can you see? ### Findings and Reasoning * **Observations:** The 6.1 shows intrinsic discoloration (darkening). It is also slightly infra-occluded (sitting lower than the occlusal plane). * **Reasoning:** The infra-occlusion is a clinical sign of ankylosis, which can be confirmed with a percussion test. The discoloration indicates a previous traumatic event affecting the pulp. ## Case: Consequences of Repositioning Primary Teeth ### Question A 14-month-old boy sustained an intrusive and palatal luxation of the 5.1. The clinician repositioned the tooth under local anesthetic. Look at the 12-month follow-up versus the 4-year follow-up. What happened? ### Findings and Reasoning * **12-Month Follow-up:** The tooth appeared to have healed nicely in the right position with no discoloration. * **4-Year Follow-up:** The permanent successors (1.1 and 2.1) show significant defects, including crown malformation, enamel hypoplasia, discoloration, and dilaceration. * **Reasoning:** Repositioning a primary tooth is high risk. In this case, the act of repositioning likely pushed the primary root or a blood clot into the developing permanent tooth germ, causing irreversible damage. The consensus is **not** to reposition primary teeth. ## Case: Lateral Luxation and Occlusal Interference ### Question Look at these two different cases of lateral luxation. How does the clinical presentation change the treatment approach? ### Findings and Reasoning * **Case A (Interference):** The teeth have been pushed so far back that there is a "step defect" and the child cannot bite properly (occlusal interference).

He presents with blood everywhere and tissues over his mouth. You lift the lip and see multiple displaced teeth and soft tissue trauma. What is the systematic management? ### Findings and Reasoning * **Diagnosis:** Use a maxillary occlusal radiograph (size 2 film at 65 degrees) to determine if teeth are intruded or avulsed. * **Clinical Findings:** The 6.2 appears palatally luxated. Other teeth (5.2, 5.1, 6.1) may be intruded. * **Management:** * If intruded, there is an 80% chance of re-eruption but a 1 in 3 chance of complications. * Because of the extent of the soft tissue injuries and gingival wounds, this specific case requires referral to a pediatric dentist for debridement and suturing under general anesthetic. ## Case: "Little Johnny" (Complex Trauma) ### Question Little Johnny fell off the monkey bars.
