Intensity of quartz-tungsten-halogen light-curing units used in private practice in Toronto.

BACKGROUND: The authors conducted a study to determine light intensity and heat/glare measurements of quartztungsten-halogen (QTH) light polymerization units used in dental offices. METHODS: Research assistants visited 100 dental offices and assessed 214 QTH light units. They recorded each unit's model, age, service history, light intensity and heat/glare emissions. RESULTS: Mean light intensity was 526 milliwatts per square centimeter (120-1,000 mW/cm2), with 26 units having intensity less than 300 mW/cm2. The mean light unit age was 5.6 years. Light units older than three years had significantly lower output intensities than those that were one, two or three years old. The authors found a wide range of heat/glare measurements (3-300 mW/cm2), with 4.6 percent of the units having values greater than 50 mW/cm2, including three with values of more than 200 mW/cm2. The mean light intensity of units serviced in the preceding year was 539 mW/cm2; it was 418 mW/cm2 for units serviced from one to six years previously. CONCLUSIONS: Light intensity and heat/glare values varied among the 214 units; some units had values well outside the recommended levels. Each unit's age and service history significantly affected its intensity. An awareness campaign is needed to promote testing, repair or replacement of light polymerization units. Periodic testing of light polymerization units should be considered by regulatory bodies to ensure optimum quality of composite restorations. CLINICAL IMPLICATIONS: Light polymerization units in some private dental offices in Toronto had intensities that may result in composites restorations with inferior properties. Dentists need to regularly monitor the intensity of the light polymerization units and maintain the units to ensure quality composite restorations.

Clinical evaluation of prazosin in 20 private practice patients.

The safety and efficacy of prazosin alone and in combination with polythiazide are being assessed in an ongoing study of private patients. All patients entering the study have diastolic pressures consistently greater than 100 mm Hg while taking placebo. Thus far, 20 patients have been given therapy for periods ranging from three to 10 months. In patients with mild hypertension, prazosin in a dosage of 5 mg three or four times a day was consistently effective in lowering blood pressure to less than 100 mm Hg and often reduced it to less than 95 mm Hg. The patients with moderate to severe hypertension responded particularly well when polythiazide was added to prazosin, while those continuing to receive prazosin alone for a comparable period showed no further improvement. Few if any side effects were observed which can be attributed to prazosin.

[The elderly patient in private practice].

The aim of this study was to get an overview on therapeutic measures and recall compliance of elderly patients treated in a private dental office. Data regarding the dental treatment und prosthodontic rehabilitation were collected from a total of 429 patients who were 65 years old and older (average: 75.8 years). 94 patients (23%) were edentulous and had dentures in both jaws, whereas 335 patients still had remaining teeth in one or both jaws. Only 8 patients had a full complement of teeth. 239 patients (55%) had complete oral rehabilitation. Few fixed partial prostheses and mainly removable partial und complete dentures were inserted. 190 patients did not get new reconstructions, because 1) they did not need it, or 2) they did not want it. In some cases, existing prostheses could be adapted or repaired. Almost all patients with remaining teeth were in need of periodontal treatment. 54% of them underwent periodontal therapy. Maintenance care was supported by regular recall. 65% of the patients appeared regularly according to their individual interval. A strong correlation could be established between regular recalls, the extent of rehabilitation and the number of remaining teeth.

Dental injuries of permanent teeth treated in private practice in Athens.

Although there are several epidemiological studies on dental trauma internationally, there are not many studies that record, analyse and follow different kinds of dental trauma treated in a private office, and that evaluate how parameters such as type of dental trauma, as well as time lapse until treatment might influence the final outcome and the prognosis of the teeth. The sample consisted of 242 patients, 6-17 years of age, with 369 injured teeth treated within a period of 5 years. All the case were treated by the first author and were followed for at least 3 years. The treatment modalities used were based upon the clinical examination and the history of the case and included direct and indirect pulp capping, partial pulpotomy, pulpotomy, pulpectomy and splinting. The type of trauma was classified based on WHO classification partially modified. Seventy six percent of the teeth suffered only hard tissue injuries and 22% had only periodontal ligament PDL) trauma. Of the total number of teeth class I represented 3%, class II 59%, class III 20% and class IV 2%. Of the PDL injuries 14% of the teeth suffered concussion, 69% luxation and 17% exarticulation. The highest incidence of dental trauma was observed at the age of 10. Sixty eight percent of the patients sought treatment 3 days or more after the trauma had occurred delayed treatment), while only 32% within the first 3 days (immediate treatment). The main reasons for delayed treatment were neglect (50%) and unawareness 37%). Of the teeth with delayed treatment 43% became necrotic, while only 28% of the teeth that were treated on time needed pulpectomy. Luxations caused more pulp necrosis (46%) than Class I (0%) Class II (7%) or Class III (34%) type of trauma. The data from this study suggested that a most of the dental injuries on permanent teeth were class II or III type, b) a high percentage (68%) of the patients sought treatment more than 3 days after the injury (delayed treatment), c) delayed treatment caused more necrotic teeth, d) the public should be informed of the importance of immediate treatment in an effort to improve the prognosis of the pulp, e) dentists should be informed of the appropriate treatment of dental injuries since 10.3% of the cases were mistreated.

Cervical radiculopathy treated with chiropractic flexion distraction manipulation: A retrospective study in a private practice setting.

BACKGROUND: Although flexion distraction performed to the lumbar spine is commonly utilized and documented as effective, flexion distraction manipulation performed to the cervical spine has not been adequately studied. OBJECTIVE: To objectively quantify data from the Visual Analogue Scale (VAS) to support the clinical judgment exercised for the use of flexion distraction manipulation to treat cervical radiculopathy.Design and setting A retrospective analysis of the files of 39 patients from a private chiropractic clinic that met diagnostic criteria for inclusion. All patients were diagnosed with cervical radiculopathy and treated by a single practitioner with flexion distraction manipulation and some form of adjunctive physical medicine modality. Main outcome measures The VAS was used to objectively quantify pain. Of the 39 files reviewed, 22 contained an initial and posttreatment VAS score and were therefore utilized in this study. RESULTS: This study revealed a statistically significant reduction in pain as quantified by visual analogue scores. The mean number of treatments required was 13.2 +/- 8.2, with a range of 6 to 37. Only 3 persons required more treatments than the mean plus 1 standard deviation. CONCLUSION: The results of this study show promise for chiropractic and manual therapy techniques such as flexion distraction, as well as demonstrating that other, larger research studies must be performed for cervical radiculopathy.

Osseointegrated implant for single-tooth replacement: a retrospective multicenter study on routine use in private practice.

BACKGROUND: Implant restorations first started with total edentulism. Later, the scientific community gave its approval for restorations in partial edentulism, and only recently some studies confirmed the validity of the treatment for single-tooth replacement. PURPOSE: The purpose of the study was to evaluate implant survival and prosthesis stability of Brånemark implants (titanium screws) when used routinely for single-tooth replacement in all regions. MATERIALS AND METHODS: Two hundred and fourteen patients received 252 implants for single-tooth replacement over a period of 8 years at five private clinics in Italy. The patients were treated in accordance with the protocol for Brånemark implants, and the data gathered have been analyzed according to established evaluation methods. RESULTS: During the observation period, 10 failures were recorded and 229 restorations were carried out. After the first year of loading, the total cumulative survival rate (CSR) was 96%, which then remained stable over the study time. The most frequent complication was loosening of the abutment screws (n = 22), amounting to 35% of all of the complications. This problem was related mainly to earlier types of abutments, whereas the more recent design, CeraOne abutment, showed a low frequency of screw loosening. CONCLUSIONS: The high survival rate, which is similar to that presented for prospective multicenter studies for single-tooth restorations with Brånemark implants, led to the conclusion that the use of this treatment modality is a reliable treatment for routine use in all oral regions.

[An empirical report on fissure sealing in private practice with a duration of up to 10 years].

This study reports a follow-up on 2415 occlusal sealings performed in a dental office. After nine to ten years service time, the survival rate of all sealed surfaces dropped to 69.5% because of either occlusal or interproximal carious activities. Retention of the sealings was intact in 91.5% after one year, but dropped to 58.2% after nine years. In the control group 49.3% of the grooves showed either caries or fillings during the last check-up whereas this occurred in only 7.3% of the sealed teeth (ratio 7:1). The difference among those two groups was even bigger (45.7% vs. 5%, ratio 9:1) when excluding all two-sided fillings. The costs of restoring one tooth surface in the control group was on average two to three times higher than for the sealings group. There is no doubt about the beneficial prophylactic effect of the use of sealants, even in the context of the private dental office, and no inconvenient side-effects have been found. The results concerning the retention rate of sealing in this study from a private dental office are comparable with the average of those reported in many papers from U.S. Dental Schools, they are even slightly better for the caries incidence.

Job satisfaction and retention of social workers in public agencies, non-profit agencies, and private practice: the impact of workplace conditions and motivators.

The authors examine a selected array of agency-influenced work and employment conditions and assess their impact upon social workers' job satisfaction, motivation, and intention to seek new employment. The study makes correlations with past empirical studies on job satisfaction and retention, with staff development concerns as stated in social work administration textbooks, and with conditions subject to administrators' influence. Some specified motivational issues included are salary, fringe benefits, job security, physical surroundings, and safety. The analysis demonstrates the contribution of certain contextual and motivational factors to a prediction of job satisfaction or of intent to leave the organization.
