Buonocore Memorial Lecture. Dentin caries: progression and clinical management.

A fundamental issue of restorative treatment is assessing the different conditions of cases not only from tooth-to-tooth but also from the activity of each caries lesion and the size of the cavity. In addition, restorative treatment is sometimes carried out for prosthetic and cosmetic purposes and involves cutting sound, unaffected dentin. These aspects are outlined in classic textbooks and are based on the principles described by Black (1908). However, each factor and its relative importance has changed over the years. Significant time has been devoted to improving the important technical aspects of performing restorative treatment. Traditionally, these aspects have primarily been related to cavity design, choice of restorative material and the clinical procedures involved. In this context, Dr Michael Buonocore's contributions must be recognized because the adhesive technique he introduced has become an integral part of modern operative dentistry. Operative dentistry today also focuses on cavity design and selecting restorative materials. Less effort has been placed on incorporating what is known about the pattern of caries progression and how it relates to caries removal or excavation. Although the reaction pattern of the pulp-dentin organ is quite different in terms of the nature of active (rapid-progressing) and arrested (slow-progressing) lesions, no widespread major distinction has been made regarding the different restorative treatment approaches in these situations. This presentation updates the progression and clinical management of dentin caries and how it relates to treating deep caries lesions.

Cvek pulpotomy: report of a case with five-year follow-up.

Partial pulpotomy (Cvek pulpotomy) is the treatment of choice for injured permanent incisor teeth with exposed vital pulp tissue and immature apices. This treatment preserves pulpal function, thus allowing continued root development. The present report describes the case of a permanent incisor with incomplete root end closure that underwent a Cvek pulpotomy, with subsequent apical closure. Five years post pulp therapy, the tooth remained symptom free.

Histopathologic study on pulp response to single-bottle and self-etching adhesive systems.

This study compared the pulp response to seven adhesive resins (three single-bottle and four self-etching primers) and their companion resin composite systems with a commercial calcium hydroxide material when applied to exposed monkey pulps. The control group was capped with Dycal (DY), while the experimental groups were capped with one of the following adhesive resin systems: AQ Bond (AQ), Single Bond (SB), Imperva Fluorobond (IF), One Step (OS), Prime&Bond NT (PBNT), Perme Bond F (PBF) and One-up Bond F (OBF). Histopathologic evaluation of pulp tissue disorganization, inflammatory cell infiltration, reparative dentin formation and bacterial penetration at the 3rd, 30th and 90th post-operative days was done using light microscopy. Data were analyzed using the Kruskal-Wallis test followed by the Least Significant Difference Test to determine differences between the control group and the experimental groups at each observation period. The correlation of inflammatory cell infiltration and bacterial presence was investigated by the Kendall correlation analysis. All tests were performed at a 95% level of confidence. The pulpal responses of groups DY, SB, OS, PBF and OBF were generally characterized by none-to-mild pulp tissue disorganization and inflammatory cell infiltration. Also, initiation of reparative dentin formation was found earlier in Group DY, resulting in more complete dentin bridges at the 30- and 90-day observation periods. Groups AQ, IF and PBNT had significantly more inflammatory cell infiltration and a lower incidence of reparative dentin formation than Group DY. A significant correlation was detected between inflammatory cell infiltration and the presence of bacteria. It is concluded that the pulp response to SB, OS, PBF and OBF is not significantly different from the calcium hydroxide preparation. However, calcium hydroxide capping resulted in a higher incidence and faster rate of reparative dentin formation.

Pulpal therapy for primary teeth: formocresol vs electrosurgery: a clinical study.

Post-operative clinical and x-ray findings on 80 primary molars were evaluated. These molars had undergone pulpal therapy by 2 techniques: pulpotomy with formocresol and with electrosurgery. The sample was selected from children between the ages of 4 and 7. A criterion for inclusion was each child must have at least 2 primary molars with pulp exposed by caries. Experimental molars with 1 or more of the following clinical or radiographic signs and symptoms were excluded: mobility, sensitivity to percussion, the presence of fistulae, groove drainage, apical or internal resorption, fetid smell and compromised furcation. Also excluded were patients previously diagnosed with diabetes, cardiopathy and renal alterations. Initially, a dinical and radiographic examination was carried out, followed by another at 1, 3 and 6 months after application of the techniques. No significant differences were found at the end of the period. However, electrosurgery had an advantage: it was faster to apply and dispensed with the use of formocresol. Further research is suggested, using larger samples and shorter evaluation periods.

Adhesive reattachment of a tooth fragment: the biological restoration.

Recent developments in restorative materials, placement techniques, preparation design, and adhesive protocols allow clinicians to predictably restore fractured teeth. Using a minimally invasive approach, treatment of the maxillary anterior region can be effortlessly completed within a single appointment. If the original tooth fragment is retained following fracture, the natural tooth structures can be reattached using adhesive protocols to ensure reliable strength, durability, and aesthetics. This article discusses the adhesive reattachment of a tooth fragment to a fractured incisor using a conservative preparation technique.

Outcomes of vital primary incisor ferric sulfate pulpotomy and root canal therapy.

PURPOSE: To compare ferric sulfate (FS) pulpotomy and primary tooth root canal therapy (RCT) in cariously exposed vital pulps of primary incisors. METHODS: A total of 133 incisors in 50 children were randomly selected to be treated by FS pulpotomy (64) or RCT (69). RESULTS: Two years after treatment, 77 incisors (41 FS pulpotomy, 36 RCT) were available for clinical and radiographic examination. There was no clinical evidence of pathosis in 78% of FS pulpotomy-treated and 100% of RCT-treated incisors. Two independent pediatric dentists evaluated periapical radiographs of the treated incisors. Incisors were classified into 1 of 4 treatment outcomes: N, normal treated incisor; H, nonpathologic radiographic change present; PO, pathologic change present, but not requiring immediate extraction; PX, pathologic change present, extract immediately. Survival analysis was applied. A moderate level of agreement between raters was found for incisors with outcome PX (K = 0.54). Intra-rater reliability was substantial for incisors with outcome PX (K = 0.61). No difference was demonstrated in the proportion of FS pulpotomy- and RCT-treated incisors rated PX at the 2-year recall (x2 = 0.6). RCT incisors demonstrated a significantly higher survival rate than FS pulpotomy incisors at 2 years (p = 0.04). CONCLUSIONS: Treatment outcomes for RCT incisors were not significantly different from FS pulpotomy-treated incisors at 2 years; however, at 2 years the survival rate of RCT incisors was statistically greater than that of FS pulpotomy-treated incisors.

Restoration modalities of severely injured anterior teeth--gingival integration, papillae support, and predictable imperfections.

This article presents 4 cases, each describing a different dental trauma and a different treatment modality. Because of various limitations, none of the results presented is esthetically perfect, but the outcomes were acceptable to both the operators and the patients. Such limitations should be predicted and discussed with patients before beginning treatment and should be regarded as acceptable compromises, unless other less conservative treatments are to be used.

Consequences of posterior cusp fracture.

Although posterior cusp fracture occurs frequently, its consequences are not well-delineated. This study recorded short-term outcomes (distribution of fractured teeth and cusps, fracture severity, and treatment received up to two years postfracture) for 517 fractured teeth from 498 subjects at a large group practice. Maxillary and mandibular tooth fractures occurred with similar frequency. In the maxillary arch, first and second molars and premolars fractured with roughly the same frequency; premolar fractures were more severe. In the mandible, first molars accounted for approximately 50% of all fractures and were most likely to be severe fractures. Nonholding cusps were more likely to fracture in both arches. Proportions of fractured teeth receiving "catastrophic" treatment were low (3% extraction; 4% endodontic treatment) and the large majority of fractured teeth were treated in a single visit using direct restorative materials. A knowledge of the relatively small proportions of fractured teeth that suffer serious consequences and the tooth-specific distributions of cusp fracture should help dentists and patients to make informed decisions regarding preventive restorative intervention prior to fracture.

Caries control and other variables associated with success of primary molar vital pulp therapy.

PURPOSE: This research evaluated initial treatment of deep dental caries with caries control (CC) procedure and the effect of other factors on the success of indirect pulp therapy (IPT) and formocresol pulpotomy (FP). METHODS: Retrospective chart audits were performed on 226 primary molars with deep caries approaching the pulp that were treated using IPT and FP. Mean follow-up was 3.4 years. CC with glass ionomer cement (GIC) was performed on 50 of the 226 teeth 1 to 3 months before pulp therapy. RESULTS: IPT therapy was successful 94% of the time, whereas FP was successful 70% of the time. The initial use of CC increased the IPT/FP success rate to 92% vs a 79% success rate in teeth without CC. Primary molar FP success on primary first molars was 61% vs 83% in second molars. IPT therapy was successful 92% of the time for first molars vs 98% of the time for second molars. Thirty-six percent of the FP-treated teeth exfoliated early vs 2% of the IPT-treated teeth. Primary first molars with reversible pulpitis had a higher success with IPT (85%) vs FP (53%). The type of final restoration did not affect IPT or FP success, except that FPs restored with an immediate IRM (Dentsply/Caulk, Milford, Del) restoration decreased success to 39%. CONCLUSIONS: IPT for the treatment of deep dental caries lesions produced greater long-term success than FP. FP success in primary first molars was lower compared to IPT success, especially in teeth with reversible pulpitis. Also FP-treated teeth showed significantly earlier exfoliation patterns. The prior treatment of deep dental caries lesions with CC procedures improved the subsequent IPT or FP success.

A retrospective evaluation of pulpotomy as an alternative to extraction.

Pulpotomy was performed as an alternative to extraction on 26 teeth over a period of 88 months. Patients were recalled to evaluate the status of each tooth. Seventeen teeth were still functioning with the original pulpotomy and amalgam restoration for periods of between 14 and 88 months. Five teeth were lost after an average of 35 months because they became symptomatic and the patients were unable to afford root canal therapy. Four teeth became symptomatic after an average of 36 months but the patients' economic status had changed and they were able to afford root canal therapy and keep the teeth functioning. The data suggest that pulpotomy may be an alternative to extraction for those patients who are unable to afford conventional endodontic therapy. This procedure has the potential to postpone the loss of the tooth for up to 88 months.
