Melatonin plays an essential role in the regulation of bone growth. The actions that melatonin exerts on odontoblasts may be similar to its action on osteoblasts. This research aimed to evaluate the pulp response to melatonin used for direct pulp capping to evaluate the antioxidant effect of melatonin administered orally and its influence on dental pulp. Direct pulp capping was performed on the upper molars of Sprague Dawley rats using melatonin or Mineral Trioxide Aggregate (MTA). The study groups were: MTA; Melatonin; MTA + Melatonin administered orally; and Melatonin + Melatonin administered orally. In the latter two groups, the animals drank water dosed with melatonin ad libitum (10 mg/100 mL). After 30 days, the animals were sacrificed, and 5 ml of blood, the kidneys, and the liver were extracted in order to evaluate oxidative stress using thiobarbituric acid reactive substances testing (TBARS). Fragments of the maxilla containing the study molars were prepared for histological evaluation. The degree of pulp inflammation and pulp necrosis, the presence of reparative dentin and dentin bridging the pulp chamber, the presence and regularity of the odontoblastic layer, and the presence of pulp fibrosis were evaluated. No significant differences were found between the four study groups for any of the studied histological variables. The oral administration of melatonin did not modify the local effects of MTA or melatonin on dental pulp, or reduce basal-level oxidative stress. The effect of melatonin on pulp is similar to that of MTA and may be used as an agent for direct pulp capping.

Direct pulp capping involves the application of dental materials to the exposed pulp in an attempt to act as a barrier, protect the dental pulp complex and preserve its vitality. The materials for direct pulp capping should ideally adhere to dental pulp tissue as soft tissue and dentin as hard tissue with tight sealing. We therefore developed visible light-induced crosslinkable gelatin which is capable of adhesive to soft tissue and hard tissue.

Indirect Pulp Capping

The dental pulp was capped indirectly or directly, or partial vital pulpectomy was performed on the 12 functionally most important teeth of 24 beagle dogs. For pulp capping, calcium hydroxide was used, followed by zinc phosphate as a lining, and the preparation was restored with amalgam or composite material. Histological sections were prepared and examined for degree and type of pulp inflammation (hyperaemia, pulpitis, necrosis or gangrene). Degenerative changes of dental pulp (vacuolation, calcification, amyloid or hyaline changes) were also determined. For indirect pulp capping the width of predentine in crown and root dental pulp was measured, and for direct pulp capping and partial pulpectomy (vital pulpotomy) the width and quality of the dentinal bridge were graded. The radical method of partial vital pulpectomy of the coronal part of the dental pulp in dogs produced better quality and continuity of the dentinal bridge than the less radical method of direct pulp capping. This was particularly obvious in small single root teeth such as incisors.

SUMMARY This study evaluated the pulpal response in human dental pulp to direct pulp capping with the Single Bond Adhesive System (SBAS) after 10% or 37% phosphoric acid etching and after capping with Calcium Hydroxide (CH). The degree of bleeding and hemostasis conditions was considered during the adhesive technique. The pulps of 78 sound premolars were capped with SBAS after 37% phosphoric acid etching (Group I) or 10% phosphoric acid etching (Group II) and CH (Group III-control). The cavities were restored with a resin composite (Charisma). After 1, 3, 7 and 30 days, the teeth were extracted and processed for light microscopical examination (H/E, AgNOR silver stain and Brown-Brenn). The patients were followed for postoperative symptomatology evaluation. Clinical results showed the possibility of hemostasis with saline solution only. There was no statistical difference between bleeding generated by 10% and 37% acid solutions. In some cases, contact of the pulp tissue with SASB started the bleeding process, thus damaging the adhesive technique. The histological response was similar in Groups I and II, without signs of cellular differentiation and dentin neoformation up to 30 days. Bacteria were not observed in any specimens. In the control group (CH) at day 7, the pulps exhibited cells with high synthetic activity (Ag-NOR-positive) underneath the area of coagulation necrosis. Dentin bridging was observed at the thirtieth day. The postoperative period was asymptomatic for all groups. In conclusion, SBAS should be avoided for vital pulp therapy, while CH remains the capping agent of choice for mechanically exposed human dental pulp.
