Combining the Non-Surgical Treatment with Extracts of Croton Lechleri and Myrciaria Dubia to Solve Gingival Cleft

Nowadays, the "pink" aesthetic possesses a significant role in the success of a dental treatment. Extended or small recessions should be solved to achieve harmony between tooth and gingival tissue. Gingival cleft (GC) is a condition that can lead to unpleasant gingival recession in the anterior area. The etiology of GC is still not clear and is often resolved using surgical treatments that, although minimal, are still interventions which can cause risks and discomfort to the patient. Therefore, this case report aims to propose a non-invasive treatment for GC, consisting of a combination of a non-surgical technique with herbal extracts therapy. A non-smoker, healthy patient was subjected to professional oral hygiene treatment supported by Croton Lechleri resin application and at-home supplementation with natural vitamin C (Myrciaria Dubia). The patient entirely followed the instructions and, after 12 months, the GC almost disappeared. In spite of its limitations, since further clinical cases are needed, the proposed non-surgical periodontal technique combined with herbal extracts therapy can represent a promising way to solve or at least reduce GC, before considering surgical treatment

The effect of miniaturized manual versus mechanical instruments on calculus removal and root surface characteristics: An in vitro light microscopic study

bjectives: The aim of this study was to evaluate by light microscopy analysis the effect of the use of miniaturised piezoelectric tips versus mini-five area specific curets on calculus removal and postoperative root surface alterations. Methods: A total of 20 extracted teeth were used. Two square surfaces (5×5 mm) were marked on each root surface with a diamond bur mounted on a high-speed handpiece. Before and after instrumentation, a series of magnified images (4.2×) of each experimental surface were taken with a standardized approach. According to a randomization list, the two surfaces on each sample were instrumented in a standardised fashion either with a mine-five curet or a slim piezoelectric tip. The images were processed using an imaging software. Data were summarised as means and standard deviations for the two outcomes (calculus and alterations.) at each time (pre and post) for both of the groups (manual and mechanical). Results: Both manual and mechanical instrumentation significantly reduced the calculus deposits (p < .001) without significant differences between the two groups. Both manual and mechanical treatments significantly increased alterations (p < .01). There was a statistically significant evidence of a greater increase in alterations from mechanical treatment. Conclusions: Slim mechanical piezoelectric tips and manual mini-five area-specific curets have similar effects on calculus removal. Manual instrumentation results in a more homogeneous postoperative root surface with less root alterations

A 3-day randomised clinical trial to investigate the desensitising properties of three dentifrices

Background: Aim of the study was to evaluate the relative abilities of three desensitizing dentifrices to the rapid relief of dentinal hypersensitivity (DH). Methods and Materials: Using a double-blind, randomized design, three dentifrices [1) containing 8% arginine, 1450ppm sodium monofluorophosphate; 2) containing 8% strontium acetate, 1040ppm sodium fluoride; 3) containing 30% micro-aggregation of zinc-carbonate hydroxyapatite nanocrystals] were compared after 3-day treatment. Participant’s DH was evaluated at baseline and after 3 days using Airblast, Tactile, Cold water and Subjective tests. Results: The final sample consisted of 85 subjects: 29 received the arginine-based dentifrice (group 1); 27 the strontium acetate-based dentifrice (group 2); 29 the dentifrice based on zinc-carbonate hydroxyapatite (group 3). All dentifrices were largely effective to reduce DH: the percentage of score reduction from baseline to 3 days was greater than 30% for all tests (except for subjective test of group 2). The comparison among the three dentifrices showed that after 3 days there was an improvement in Airblast (mean percentage of reduction 39.2% in group 1; 42.0% in group 2; 39.2% in group 3), Cold water (41.5%; 51.8%; 50%), Tactile (50.3%; 40.1%; 33.8%) and Subjective (33.1%; 17.4%; 31.4%) test scores, with differences being significant for Cold Water and Subjective tests. For Airblast and Tactile tests there were no significant differences across groups at 3 days. Moreover, no significant differences at any test were observed in a subset of patients that were followed up to 8 weeks: all dentifrices were all highly efficacious. Conclusions: This study documented that the three tested dentifrices significantly reduced DH after 3-day treatment, supporting their utility in clinical practice. This is the first report documenting the rapid relief from DH of a zinc-carbonate hydroxyapatite dentifrice

Clinical Study Risk Assessment of BRONJ in Oncologic Patients Treated with Bisphosphonates: Follow-Up to 18 Month

Objectives. Bisphosphonates related osteonecrosis of the jaw (BRONJ) is a pathological condition characterized by bone exposure or latent infection in patients treated with the drug. The aim of the study is to monitor the BRONJ level of risk health in patients with cancer, according to a preventive clinical protocol, which is firstly aimed at reducing risk factors such as the periodontal infections. Materials and Methods. 10 patients participated in the protocol and were evaluated at baseline and after 3 and 18 months of treatment with bisphosphonates, through full mouth plaque and bleeding scores (FMPS and FMBS), clinical attachment level (CAL) measurement, and the occurrence of osteonecrosis. Results. The mean plaque and bleeding were reduced and the CAL has not shown significant changes and in no cases was there manifestation of BRONJ. Conclusion. The protocol proved crucial for the maintenance of good oral health conditions by eliminating the risk of BRONJ during the observation period
