Influence of age on the behavior of dental pulp of dog teeth after capping with an adhesive system or calcium hydroxide

This study evaluated histomorphologically the influence of chronological age of the dog on the dental pulp-healing process after capping with the All Bond 2 system or with calcium hydroxide paste. The animals were divided according to age into young and adult groups. Class 5-type cavities were prepared, and the pulp was submitted to an exposure of a diameter of 0.5 mm. The pulp of the teeth was then protected with the adhesive system or with a calcium hydroxide paste. Sixty days after treatment, the results obtained with the adhesive system in the young group were significantly better than those in the adult group. With calcium hydroxide, the results were similar for both groups. The pulp treated with calcium hydroxide exhibited a complete hard tissue bridge and a pulp without inflammatory reaction, a fact not observed when the adhesive system was used. In conclusion, the chronological age of the pulp influenced the comparative results only for the adhesive system (P = 0.1), and the total results were better with calcium hydroxide than with the All Bond 2 system (P = 0.01).

Referral letters in oral medicine: an approach for the general dental practitioner

The aim of this study was to analyze the contents of referral letters related to clinical history and reason for consultation. A total of 236 consecutive referral letters were evaluated. Analysis of the referral letters was based on key items concerning patient identification. chief complaint, previous consultation. laboratory investigation and use of drugs for the chief complaint. A database was organized (Epinfo 6.04) and the chi (2) test (a = 0.05) was applied to the results. of the 800 files examined. only 30%, (236) had a referral letter. of the 236 referral letters. 67% were from dentists, 22% from physicians and 11% from unidentified professionals. Patient age did not appear in 70%, of the letters and the chief complaint was mentioned only in 55%. The letters had no details such as description of the oral lesion (80%), anatomical site (34%), size (99%), symptoms (83%), or period of evolution (92%). Clinical diagnosis was not included in 84% of the letters. Less than 5% of the referral letters contained information about previous consultation and laboratory investigation. The chi (2) test showed significant differences for ail items of the referral letter. Referral letters did not satisfy minimal requirements about clinical history or reason for consultation. leading to failed communication among professionals. Based on this study, we suggest that standard letters are important to improve the quality of the letters, reducing the rate of omission of relevant items.
