Overview of method of research: Case Report

Case History:
13 year-old male fell and hit his maxillary incisors on the floor. Proper initial precautions were taken and upon clinical examination and transillumination the lateral incisors were classified with a subluxation injury and were both slightly mobile. The central incisors both presented with MFLI Ellis Class II fractures. These centrals also displayed moderate mobility, sulcular bleeding, mild palpation sensitivity and were diagnosed with “extrusive luxation”.

Treatment:
1. Prophy brush to clean labial surfaces of incisors.
2. Dead-soft ligature wire was twisted upon itself to make a double strand and left incisors were treated with L-Pop for 20 sec., air thinned and cured for 10 sec.
3. The splint wire was placed passively across the left lateral incisor at the gingival 1/3 in order to allow continued use of ortho retainer. A small amount of compomer (Hytac) was placed on each tooth and pressed into place with a hand instrument and light cured for 40 seconds. The same was repeated for the central.
4. Same steps were taken for the right incisors and proper occlusion was verified.
5. Exposed dentin was covered with a thin layer of vitrebond and peripheral enamel was reduced slightly with a diamond bur.
6. Self-etching adhesive was added to liner and enamel for 30 seconds.
7. Composite “bandage” was placed with the use of a matrix band and wedge.
8. The child was prescribed amoxicillin to help in periodontal and pulpal healing.
9. PA radiograph was taken and revealed NSF.
10. Re-evaluation in 8 days revealed unremarkable findings other than slight mobility of the central incisors. Patient reports wearing his ortho retainer daily.
11. The splint was removed with a slow speed diamond bur and all incisors were asymptomatic with unremarkable findings.

Discussion:
Compomer materials are polyacid-modified, resin-based composites. Although they contain glass filler particles, they are appropriate for interim restorations, with sufficient strength and durability for a passive splint yet are cut away easily once they have served their purpose.

Key points/Summary:
Using a self-etching adhesive bonding system and compomer material facilitates both the resin bonding and its removal.

Assessment of Article:
Nothing “earth shattering”, but interesting enough.
