Patient Overview
A male in his thirties presented with complaints of sensitivity and discomfort localized to his lower right first molar (tooth 46). He reported no systemic health issues and had no known allergies.
Presenting Complaint
The patient described intermittent, sharp pain triggered by hot or cold food and beverages. The discomfort had been present for several weeks. He had also noticed a visible cavity in the buccal pit area of the tooth.
Clinical Examination
On inspection, a deep carious lesion was identified in the buccal pit of tooth 46, with associated discolouration and softening of enamel and dentin. Mild tenderness was elicited on probing, but percussion testing was negative, indicating that the pulp had not yet become inflamed or infected.
Diagnosis
The findings were consistent with buccal pit caries extending into the dentin, without signs of pulpitis or periapical pathology. The tooth remained vital.
Treatment Provided
1. Carious Tissue Removal
- The lesion was carefully excavated to remove all demineralized and infected dentin.
- Care was taken to avoid pulp exposure while ensuring complete debridement.
2. Pulp Protection
- A calcium hydroxide liner was applied to the deepest portion of the cavity.
- This helped protect the pulp and stimulated secondary dentin formation.
3. Restoration
- The cavity was restored using composite resin, selected for its aesthetic qualities and reliable sealing ability.
- The material was incrementally placed and cured to ensure a durable and snug fit.
Postoperative Plan
The patient tolerated the procedure well and reported immediate relief from thermal sensitivity. A follow-up appointment was scheduled to evaluate the success of the restoration and monitor the pulp status over time.
Notes
Buccal pit caries on posterior teeth like tooth 46 can be deceptively invasive due to the deep pit and groove anatomy. This case highlights the importance of early diagnosis and the use of pulp-protective materials such as calcium hydroxide when lesions approach the pulp. Composite resin serves both functional and aesthetic purposes in restoring the tooth.
Conclusion
Effective management of deep buccal pit caries in tooth 46 was achieved through meticulous excavation, judicious use of pulp-protective lining, and a well-executed composite restoration. Ongoing follow-up is essential to ensure long-term success and tooth vitality.
