Interdental plaque reduction after use of different devices in young subjects with intact papilla: A randomized clinical trial.

OBJECTIVES: To determine the efficacy of 4 different oral hygiene regimens involving adjunctive interdental cleaning devices in unsupervised young subjects with intact interdental papilla. MATERIAL AND METHODS: Sixty periodontally healthy subjects were randomly allocated to 4 groups following different oral hygiene regimens (T-7): use of manual toothbrush alone; manual toothbrush plus dental floss; manual toothbrush plus interdental brushes; and manual toothbrush plus rubber interdental picks. Oral hygiene instructions (OHI) were given. One week after (T0), professional supragingival scaling and polishing was performed, and subjects were then reseen every 2 weeks (T14 and T28). At T-7, T0, T14 and T28, full-mouth plaque score (FMPS), full-mouth bleeding score (FMBS) and angulated bleeding index (AngBI) were taken. RESULTS: During the first week (T-7/T0 unclean phase), FMPS decreased significantly in all groups except the group using dental floss. At T28, a significant decrease in FMPS (P < .001, all groups) and FMBS (P < .05, all groups except the group using flossing P < .001) was noted. Interdental FMPS showed significantly lower values in subjects treated with interdental brushes or rubber interdental picks vs toothbrushing alone (P < .05). The use of interdental picks was associated with reduced interdental FMBS when compared to flossing (P < .05). CONCLUSION: In young subjects, with no interdental attachment loss, toothbrushing or toothbrushing and adjunctive interdental cleaning devices such as dental floss, interdental brushes or interdental rubber picks can significantly reduce both plaque and gingival inflammation. Use of interdental brushes or rubber picks reduces more interdental plaque in comparison with toothbrushing alone.

Conservative surgical management of patients with bisphosphonate-related osteonecrosis of the jaws: a series of 120 patients.

We evaluated retrospectively the efficacy of local resection for patients who presented with bisphosphonate-related osteonecrosis of the jaw (BRONJ). We studied 120 subjects with who required local resection of 129 BRONJ lesions that had not responded to medical treatment. The primary outcomes were improvement of the clinical stage of BRONJ and resolution of disease, and the secondary outcome was the influence of the surgeon's experience on the healing of the lesions. Age, sex, underlying diseases, smoking, and coexisting conditions were recorded. Logistic regression analysis was used to isolate factors that could potentially affect the outcome. Most of the lesions (n=107, 84%) improved postoperatively, 20 showed no change, and one got worse. One patient died. Stratification indicated complete healing and total resolution of disease for all 26 stage I lesions, improvement for 67 of the 77 stage II lesions, and for 14 of the 25 stage III lesions. The disease resolved in 67 of the 69 stage II lesions, and 14 of the stage III cases. Logistic regression indicated that smoking and the stage of disease could affect the outcome. Analysis of the surgeons' learning curve showed that performance improved significantly over time. Complete healing after local resection increased from 40% to 80% over a period of eight years (p<0.001). We conclude that local resection may be the treatment of choice in BRONJ stages I and II. Stage III might be better treated with either resection or clinical monitoring according to the condition of the patient.

Risk factors influencing BRONJ staging in patients receiving intravenous bisphosphonates: a multivariate analysis.

The objective of this study was to determine, retrospectively, the influence of various risk factors on the staging of bisphosphonate-related osteonecrosis of the jaw (BRONJ) in a population attending a department of dentistry and oral surgery in Italy. Data were collected from the electronic and paper medical records of 90 patients receiving intravenous bisphosphonates. Two experienced and calibrated examiners used the American Association of Oral and Maxillofacial Surgeons updated 2009 classification to record the stage of BRONJ lesions. Multivariate ordinal logistic regression was performed to determine individual risk factors negatively affecting BRONJ staging. The factors associated with a worse BRONJ staging were high bisphosphonate cumulative dose (odds ratio (OR) 1.70, 95% confidence interval (CI) 1.02-2.82; P=0.04), smoking (OR 1.80, 95% CI 1.03-2.80; P=0.04), steroid intake (OR 1.70, 95% CI 1.00-2.87; P=0.05), and a maxillary location of the lesion (OR 3.50, 95% CI 1.81-6.77; P<0.01). Tooth extraction was the event that most negatively influenced BRONJ staging (OR 1.60, 95% CI 1.00-2.81; P=0.05), in comparison to other events such as prosthetic trauma, implant treatment, oro-dental infection, and periodontal disease. Certain clinical and medical risk factors may determine a more severe staging of BRONJ lesions. Future studies are necessary to confirm these findings.

The influence of educational level and oral hygiene behaviours on DMFT index and CPITN index in an adult Italian population: an epidemiological study.

OBJECTIVES: To estimate the influence of educational level and oral hygiene behaviours on the prevalence and severity of dental caries and periodontal disease in an adult Italian population attending the Oral Hygiene department of a public Dental Clinic. METHODS: Dental caries was diagnosed according to the World Health Organization criteria. The DMFT index (decayed, missing, filled tooth) was used to record the dental caries' experience. The periodontal status was assessed using the community periodontal index of treatment needs (CPITN). Questionnaires on educational level and oral hygiene behaviours were also collected. RESULTS: A total of 350 patients were enrolled. The mean DMFT value reported was 4.37 ± 3.06, and higher values were observed for male patients (P < 0.05). Increased CPITN scores and DMFT values were significantly correlated with lower level of education (P < 0.05). Subjects of high educational status showed significantly better oral hygiene habits (P < 0.05). CONCLUSIONS: The oral health status, in terms of periodontal disease and dental caries, appears correlated with patients' educational level.
