Use of a Penrose Drain for Decompression of a Large Periapical Lesion: A Case Report With 4.5-Year Follow-up.

Managing large cyst-like periapical lesions poses significant challenges, especially when nonsurgical treatment or retreatment options are ineffective. Despite its efficacy, decompression remains an underutilized minimally invasive alternative in modern dentistry. This case report describes the use of a Penrose drain for decompression following aspiration and irrigation to manage a large periapical lesion associated with a 56-year-old man's maxillary lateral incisor. The lesion had caused thinning and perforation of the facial and palatal cortical plates, as well as the inferior border of the nasal fossa. Cone-beam computed tomography was used to evaluate the lesion preoperatively and to assess the healing progress postoperatively. Complete 3-dimensional healing was observed after a subsequent root-end surgery performed 3.5 years post-decompression. This report suggests that decompression using a Penrose drain in combination with aspiration and irrigation could be a simple but effective modality for managing large cyst-like periapical lesions when nonsurgical endodontics are attempted and deemed ineffective.

Use of Vital Pulp Therapies in Primary Teeth 2024.

Purpose: The purpose of this study was to present an evidence-based guideline for primary teeth with deep caries or trauma requiring vital pulp therapies (VPT). Methods: A systematic review/meta-analysis on vital primary teeth resulting from trauma or caries was conducted using GRADE to assess the certainty of evidence for clinical recommendations. A decision tree was provided for choosing VPTs. Results: No articles on trauma VPT were found. For VPT in primary teeth with deep caries, indirect pulp treatment (IPT) or pulpotomy using the calcium silicate cement (mineral trioxide aggregate [MTA] or Biodentine®) show increased success over using direct pulp capping (DPC) and other pulpotomies. Different liners do not affect IPT success (high certainty) or DPC capping agents' success (very low certainty) after 24 months. It is strongly recommended, with high certainty from 24-month data, that calcium silicate cement pulpotomy is preferred over formocresol, ferric sulfate, zinc oxide eugenol pulpotomy, and other pulpotomies. Using selective caries removal and IPT for deep caries is strongly recommended with moderate certainty over complete and stepwise removal. Statistically, this results in significantly fewer pulp exposures. No caries removal and Hall technique crown may be used when indicated (moderate certainty at 24 months). For vital primary incisors with deep caries, pulpotomy was significantly better statistically than pulpectomy. Teeth diagnosed with/without reversible pulpitis pain showed comparable success after 12 months of treatment by IPT or calcium silicate cement pulpotomy. The following had little or no significant effect on MTA pulpotomy success: coronal pulp removal methods; irrigation solution; method to control hemorrhage; base over MTA; treatment in one or two visits; anterior or posterior teeth. Conclusions: Indirect pulp treatment or calcium silicate cement pulpotomy is likely to increase vital pulp therapy success over other VPTs such as direct pulp capping and other pulpotomies after 24 months (moderate certainty).

Primary Tooth Vital Pulp Treatment Interventions: Systematic Review and Meta-Analyses.

Purpose: to update the 2016 systematic review evidence for vital pulp therapy (VPT) for primary teeth affected by caries or trauma. Methods: The population, intervention, comparison, outcomes, and study (PICOS) design inclusion/exclusion was used for multiple databases. Risk of bias, meta-analyses using RevMan, and certainty of evidence was created. Results: A total of 299 studies were included; no trauma was found. Indirect pulp treatment (IPT) resulted in 97 percent success. Two calcium silicate cement (CSC) pulpotomies' success using mineral trioxide aggregate (MTA) and Biodentine® were 94 percent and 90 percent, respectively, greater than for direct pulp capping (DPC; 86 percent) and other pulpotomies (moderate certainty). The success of IPT versus pulpotomy at 24 months showed no significant difference (P=0.31). Different liners or capping agents did not affect the success of IPT (P=0.79) or DPC at 24 months (P=0.24). The two CSC pulpotomies were not significantly different based on 24-month success (P=0.34). The formocresol pulpotomy success at 24 months was significantly lower than for MTA (P=0.02). Ferric sulfate had a significant lower success at 24 months than MTA pulpotomy (69 percent versus 92 percent; P=0.03). Zinc oxide eugenol, as a singular pulpotomy, had low success (65 percent). Selective/stepwise caries removal did significantly better at avoiding pulp exposures than complete excavation (P<0.001). Complete, selective, and no caries removal (Hall technique [HT], steel crown placement with no caries removal) had no significant difference in pulp vitality success for deep caries at 24 months (P=0.29). For deep caries affecting vital incisors, pulpotomy had significantly greater success than pulpectomy (P=0.002). The following had no significant effect on MTA pulpotomy success: coronal pulp removal methods; irrigation solution; method to control hemorrhage; base over MTA; treatment in one or two visits; and anterior or posterior teeth. Conclusions: Vital pulp therapy success of indirect pulp treatment or two calcium silicate cement pulpotomies demonstrated improved success over direct pulp capping and other pulpotomies based on 24-month evidence with moderate certainty. The Hall technique did not significantly reduce pulp vitality success versus caries removal.
