Dentin-predentin complex and its permeability: pathology and treatment overview.

This review paper focuses attention on tissue changes which may take place in dentin and on localized alterations in tissue formation in the predentin area. A number of reaction patterns has been described in dentin affecting both the inorganic and organic components. Dentinal tubules may become partly or completely obturated by growth of the peritubular dentin. Precipitation of mineral salts within the tubules, which may be a reprecipitation of minerals from adjacent demineralized dentin, represents a fundamentally different mode of obturation of dentinal tubules. Initially, demineralization selectively affects the peritubular dentin. If dentin is exposed to the oral environment, the surface layer may become hypermineralized. The surface layer of dentin, exposed by grinding, becomes covered by a smear layer. Displacement of the contents of the tubules or of the odontoblasts is a characteristic change in the organic components. Odontoblast destruction or degeneration will lead to a lack of, or reduced, predentin formation. Changes in the protein components which lead to alterations in dentin permeability have also been reported. The structure of the interface between dentin and localized formations of irregular secondary dentin varies considerably. If there is no tubular communication between primary and secondary dentin, the interface will act as an impermeable barrier. Changes in dentin, including irregular secondary dentin formation, affect the permeability of the tissue. Such changes are clinically important for the outcome of all types of restorative work performed on vital teeth.

Intravenous flunitrazepam (Rohypnol) in conservative and restorative dentistry.

The study was undertaken to assess the suitability of intravenous flunitrazepam (Rohypnol) in patients requiring sedative cover for prolonged dental surgery. Fifty patients received up to 2 mg flunitrazepam to induce a satisfactory level of sedation. Further maintenance doses and local anaesthesia were given if required. The results showed the level of sedation and working conditions, as assessed by anaesthetist and surgeon, to be satisfactory in all but one patient. The majority of patients remained slightly drowsy the following morning but all stated they would undergo a similar procedure again.

The effect of supplemental oxygen on postoperative nausea and vomiting in children undergoing dental work.

Administration of 80% intraoperative oxygen has been proposed as being a cheap, safe and effective means of reducing postoperative nausea and vomiting (PONV) but no studies have been performed in the high risk paediatric population. We tested whether 80% intraoperative oxygen reduces PONV in well children undergoing elective day-stay dental treatment under general anaesthesia. Ninety-five children received standardized sevoflurane, morphine, vecuronium anaesthesia with either 30% or 80% intraoperative oxygen and no antiemetic prophylaxis in a randomized, double blind, prospective trial. There was no difference in PONV or in the use of rescue ondansetron between the groups. The total incidence of PONV was 40% in the group that received 30% oxygen and 33% in those that received 80% oxygen. High inspired intraoperative oxygen was not found to significantly reduce PONV in well children undergoing dental work under general anaesthesia.

Practice variation: learned and socio-economic factors.

Much variation exists in the practice of dentistry with regard to diagnosis of caries and recommendations for treatment. This is a particular problem with respect to the replacement of restorations, with responsible factors related to both the patient and the dentist. The aim of this paper is to look at factors, exclusive of clinical data, that may explain why there is so much variation in the practice of dentistry, and specifically pertaining to replacement of restorations. Due to the paucity of studies related specifically to dentists, findings from physician studies will be presented. No studies are available that compare variation in medical and dental practices, but since both professions deal with the provision of health care and function in similar circumstances, comparisons are arguably generalizable between the two groups. Development of clinical judgment will be explored based on dental training experiences, and two explanatory models of practice pattern variation will be discussed--the dentist as a self-fulfilling practitioner and the dentist as the patient's agent. Along with these models, the matter of uncertainty in clinical practice and the development of routines will also be discussed in light of explaining variations.

Simple and safe method to prepare patients with prosthetic heart valves for surgical dental procedures.

Temporary discontinuation of high-intensity oral anticoagulant treatment is not recommended in patients undergoing dental surgery. This policy is not based on solid data from randomized clinical trials but on expert consensus. The alternative, i.e., to continue treatment and treat patients with tranexamic acid mouthwash, often is not applicable. A prospective cohort study was carried out to evaluate bleeding and thromboembolic complications in patients bearing prosthetic heart valves and registering International Normalized Ratio (INR) values between 2.0 and 4.5, who underwent dental procedures after a 2-day suspension of warfarin treatment. One hundred four consecutive patients receiving high-intensity anticoagulation underwent 123 dental procedures after 2 days' warfarin withdrawal. No major bleeding complications occurred in the week after the procedure; minor bleeding requiring local measures occurred in two patients. No thromboembolic events and no cases of bacterial endocarditis were recorded in the 3 months after the procedure. A mean decrease in INR by approximately 1.0 U (from 2.95+/-0,59 to 1.87+/-0,46) occurred after 2 days' warfarin suspension. Seven days after reinitiation of warfarin, INR values returned to the therapeutic range in 90% of cases. The calculated average time spent at INR less than 2.0 (critical value) was 28 hours. Two days' warfarin suspension is a simple and safe policy for patients with prosthetic heart valves undergoing dental surgery.
