Humanisation and health needs in children: present or future?

AIM

For a few years, teledentistry has been an emerging innovative strategy with potential in the field of paediatric dentistry. There are still few studies in this regard, so further research is needed to verify and ensure that teledentistry is not only an accessible mode of communication, but above all effective and evidence-based. This study aimed to use a preliminary telematic approach to promote the compliance of patients in the developmental age during the first dental visit.

MATERIALS

Two hundred patients were selected according to the eligibility criteria, and distributed in two groups: a study group with the preliminary telematic approach (ATP) before the first visit and a control group with traditional first visit without ATP. Through an ordinal semi-proportional regression model, the degrees of collaboration between the study and control groups were compared, correcting the estimate for age groups, the presence of systemic pathologies, disorders of cognition, attention and learning, degree of anxiety and previous medical-dental experiences.

CONCLUSION

The preliminary telematic approach could be useful as a support to the traditional paediatric dental visit, to promote better management and fidelity of the patient, reducing anxiety and increasing collaboration during the first visit.

Antibacterial and clinical effectiveness of a mouthwash with a novel active system of amine + zinc lactate + fluoride: a randomized controlled trial

OBJECTIVES

To support the daily oral hygiene of patients experiencing gum inflammation, a new mouthwash was developed containing an amine + zinc lactate + fluoride system. In vitro and clinical efficacy was assessed using traditional methods as well as using novel site-specific and subject-specific analyses of the clinical data.

MATERIALS AND METHODS

This mouthwash was evaluated in a 12-h biofilm regrowth assay against a negative control mouthwash and in a 6-month plaque and gingivitis clinical study as compared to a negative control mouthwash. Analyses of healthy versus inflamed sites, visible plaque versus non-visible plaque sites, as well as subject-level evaluations bring new perspectives to the overall performance of this mouthwash and its significance from a patient outcome perspective.

RESULTS

Studies demonstrated that this new mouthwash provided long-term (12-h) antibacterial activity after single application in vitro and reduced clinically all plaque and gingivitis parameters after 3 months and 6 months of use when compared to the negative control mouthwash. Examination of site-level and subject-level data determined that this mouthwash significantly increased the number of healthy sites in the oral cavity and significantly improved the gum health of subjects in the study, as compared to the negative control mouthwash.

CONCLUSIONS

In vitro and clinical research has demonstrated the antibacterial and clinical benefits of this mouthwash containing an amine compound + zinc lactate + fluoride system.

CLINICAL RELEVANCE

Our subject-specific and site-specific analyses provide the dental practitioner with tools that can be used to guide patients who suffer from gingivitis toward optimal product selection and use.

CLINICAL TRIAL REGISTRATION

The trial was registered at ClinicalTrials.gov (reference no. NCT05821712).

Effect of a stannous fluoride toothpaste on dentinal hypersensitivity: In vitro and clinical evaluation

BACKGROUND

The authors conducted an in vitro and a clinical study to assess the effect of a toothpaste containing stannous fluoride to occlude dentin tubules and reduce dentinal hypersensitivity.

METHODS

For the in vitro study, the authors treated the surface of human dentin specimens with test or control toothpaste slurries and then evaluated them by using various spectroscopic techniques. For the clinical study, male and female participants who met the inclusion criteria brushed their teeth twice daily for 1 minute with test or control toothpaste. The authors assessed dentinal hypersensitivity by using tactile and air blast stimuli at baseline and after 4 and 8 weeks. All statistical tests of hypotheses were 2 sided, with a significance level of α set at .05.

RESULTS

Results from in vitro studies showed that the test toothpaste effectively occluded the dentinal tubules with a deposit consisting of tin, zinc, phosphate, and silicon. The test and control toothpastes occluded the tubules 82% and 35%, respectively. Clinically, at the 4- and 8-week examinations, the test toothpaste provided statistically significant (P < .001) improvements in tactile dentinal hypersensitivity scores of 27.8% and 42.0% and in air blast hypersensitivity scores of 21.4% and 32.3%, respectively, relative to the control toothpaste.

CONCLUSIONS

The in vitro results indicate the toothpaste containing 0.454% stannous fluoride effectively coated dentin surfaces and occluded patent dentin tubules. Compared with the control toothpaste, the test toothpaste provided a significant reduction in dentinal hypersensitivity after 8 weeks of product use.

PRACTICAL IMPLICATIONS

A multi-benefit option for patients with dentinal hypersensitivity.

Gingival fibromatosis: a case report

AIM

Gingival Fibromatosis is characterised by a large increase in the gingival dimension which extends above the dental crowns, covering them partially or completely. The causes of the disease may have a genetic origin, in which case gingival hyperplasia may occur in isolation or be part of a syndrome, or acquired origin, which comes from specific drugs administered systemically. A form of gingival fibromatosis of idiopathic origin has been described. The therapy involves mainly the surgical removal of the hyperplastic gingival tissue, although in these cases recurrences are frequent.

CASE REPORT

A 9 years old male patient came to observation at the Clinic of Pediatric Dentistry of the Tor Vergata Polyclinic of Rome. After Primary Gingival Fibromatosis was diagnosed, the therapeutic choice was to wait and postpone gingivectomy at the end of the development phase.

Sinus augmentation in two patients with severe posterior maxillary height atrophy using tissue-engineered bone derived from autologous bone cells: a case report

Implant placement in the edentulous maxilla often represents a clinical challenge because of insufficient bone height after crestal bone resorption and maxillary sinus pneumatization. In this study, tissue engineering techniques were used to increase bone height in the posterior maxilla before implant placement. Periosteal biopsies were harvested, and osteoblast precursor cells were isolated and cultured on three-dimensional fleeces (nonwoven polyglactin-910 fibers connected by poly-p-dioxanon bonding sites) in vitro. Tissue-engineered bone chips were implanted into the sinus cavity using a lateral window approach. Four months post-sinus augmentation, implants were placed and subsequently restored. During a 12-month follow-up period, no implant failure was observed.

Comparative evaluation of the efficacy of three commercially available toothpastes on dentin hypersensitivity reduction: an eight-week clinical study

OBJECTIVE

The objective of this eight-week, single-center, three-cell, double-blind, and randomized clinical study was to evaluate the dentin hypersensitivity reduction efficacy of three commercially available toothpastes: 1) Colgate Sensitive Pro-Relief Toothpaste (also marketed as elmex Sensitive Professional); 2) Sensodyne Rapid Relief Toothpaste; and (3) Crest Cavity Protection Toothpaste.

METHODS

150 subjects, having two teeth with tactile and air blast hypersensitivity, were assigned to one of the three study groups (50/group). Subjects were then asked to brush their teeth for one minute, twice daily, with the given toothpaste. The dentin hypersensitivity and oral tissues were evaluated at baseline, two weeks, four weeks, and eight weeks. Comparison of the treatment groups with respect to gender was conducted using a chi-square analysis, and with respect to age and baseline hypersensitivity scores was performed using the analysis of variance (ANOVA). Within-treatment effects were analyzed using the paired t-test, while the analysis of covariance (ANCOVA) was used to examine between-treatment effects. The post hoc Tukey test was performed for pair-wise comparisons. All statistical tests were two-sided using a significance level of alpha = 0.05.

RESULTS

After two, four, and eight weeks of daily use of the products, all three groups showed a statistically significant reduction from baseline in tactile and air blast dentin hypersensitivity (p < 0.05). Colgate Sensitive Pro-Relief toothpaste produced a significant improvement in mean tactile and air blast dentin hypersensitivity scores, and was more effective than Sensodyne Rapid Relief toothpaste and Crest Cavity Protection toothpastes (p < 0.05).

CONCLUSION

Colgate Sensitive Pro-ReliefToothpaste, used twice daily, significantly reduces dentin hypersensitivity, and is significantly more effective in reducing dentin hypersensitivity than Sensodyne Rapid Relief Toothpaste and Crest Cavity Protection Toothpaste.

Rapid treatment of Class II malocclusion with piezocision: two case reports

An increasing number of adult patients are seeking orthodontic treatment to enhance their smile or their masticatory function. In this fast-paced and self-conscious society, time and esthetics have become increasingly important. One of the biggest challenges an adult orthodontic patient faces is the time spent wearing brackets. Over the years, several surgical techniques have been developed to address this issue and reduce overall treatment time. Although very effective, these techniques have proven to be quite invasive. A new, minimally invasive procedure (piezocision) is presented that combines microincisions and localized piezoelectric surgery to achieve similar results rapidly and with minimal trauma.

Comparing the efficacy in reducing dentin hypersensitivity of a new toothpaste containing 8.0% arginine, calcium carbonate, and 1450 ppm fluoride to a benchmark commercial desensitizing toothpaste containing 2% potassium ion: an eight-week clinical study in Rome, Italy

OBJECTIVE

The objective of this double-blind dentin hypersensitivity clinical study was to investigate the effectiveness of a new desensitizing toothpaste containing 8.0% arginine, calcium carbonate, and 1450 ppm fluoride as sodium monofluorophosphate (MFP), compared to that of a benchmark commercially available desensitizing toothpaste containing 2% potassium ion, dosed as 5.0% potassium nitrate, and 1450 ppm fluoride as sodium fluoride (NaF).

METHODS

A total of 80 subjects were entered into the study, and stratified into two balanced groups according to their baseline mean tactile and mean air blast sensitivity scores. The two groups were randomly assigned to use either the new arginine toothpaste or the benchmark commercially available desensitizing toothpaste containing 2% potassium ion. Subjects were instructed to brush their teeth twice daily (morning and evening) for one minute with their assigned toothpaste and a commercially available soft-bristled toothbrush. Dentin hypersensitivity examinations, which included tactile and air blast sensitivity measures, were conducted at baseline, one week, two weeks, four weeks, and eight weeks. Subject examinations were conducted by the same dental examiner at each examination period.

RESULTS

This clinical study demonstrated that the new toothpaste, containing 8.0% arginine and 1450 ppm fluoride as MFP in a calcium carbonate base, provided a significant reduction in dentin hypersensitivity when used over a period of eight weeks. The study also showed that the new arginine toothpaste provided significantly greater reductions (p < 0.05) in dentin hypersensitivity in response to tactile (38.9%, 28.8%, and 11.6%) and air blast (16.8%, 26.4%, and 33.8%) stimuli than the benchmark commercial desensitizing toothpaste containing 2% potassium ion and 1450 ppm fluoride as NaF in a silica base, after two weeks, four weeks, and eight weeks of product use, respectively.

CONCLUSION

A new toothpaste containing 8.0% arginine, calcium carbonate, and 1450 ppm fluoride as MFP provides significantly increased hypersensitivity relief (p < 0.05) as compared to a benchmark commercial desensitizing toothpaste containing 2% potassium ion, dosed as potassium nitrate, after two weeks, four weeks, and eight weeks of product use.

RESULTS

This clinical study showed that the new toothpaste containing 8.0% arginine and 1450 ppm fluoride as MFP in a calcium carbonate base provided a significant reduction in dentin hypersensitivity when used over a period of eight weeks. The study also showed that this new arginine toothpaste provided significantly greater reductions (p < 0.05) in dentin hypersensitivity in response to tactile (37.0%, 30.0%, and 12.2%) and air blast (23.9%, 32.0%, and 29.3%) stimuli than the commercial sensitive toothpaste containing 2% potassium ion and 1450 ppm fluoride as NaF in a silica base, after two weeks, four weeks, and eight weeks of product use, respectively.

CONCLUSION

A new toothpaste containing 8.0% arginine calcium carbonate, and 1450 ppm fluoride as sodium monofluorophosphate (MFP) provides significantly increased dentin hypersensitivity relief (p < 0.05) compared to a commercial sensitive toothpaste containing 2% potassium ion after two weeks, four weeks, and eight weeks of product use.

Desensitizing efficacy of a new toothpaste containing 5.5% potassium citrate: a 4-week clinical study

PURPOSE

To evaluate the desensitizing capabilities of a new toothpaste containing 5.5% potassium citrate (Colgate Sensitive Multi Protection Toothpaste) to another toothpaste containing 3.75% potassium chloride (Sensodyne Total Care F Toothpaste).

METHODS

A 4-week clinical study was conducted in 75 subjects at the University of Rome, at Tor Vergata, in Rome, Italy, using a double blind, stratified, two treatment design. Tactile sensitivity as well as air blast sensitivity assessment was used to compare the efficacy of the two products.

RESULTS

There was no statistically significant difference in tactile sensitivity scores and air blast sensitivity scores between the tested toothpastes at baseline, 2 weeks and 4 weeks. Both toothpastes provided statistically significant improvement in tactile sensitivity scores and air blast sensitivity scores after 2 weeks of use and 4 weeks of use as compared to baseline scores.

Light and scanning electron microscopic report of four fractured implants

Although they are fortunately rare, implant fractures can cause significant problems for both clinicians and patients. The authors present a light and scanning electron microscopic study of four fractured implants in two patients. Both patients had parafunctional habits (bruxism), hypertrophic masticatory muscles, and wear of occlusal surfaces. The scanning electron microscopic study of the fractured surfaces of all four implants showed the presence of fatigue striations. Bending overload was probably created by a combination of parafunctional forces, bone resorption, posterior location of the implants, and implant diameter.

[Role of computerized tomography in endosseous implantology]

The Authors are proposing the use of computerized tomography for the evaluation of osseous structures of the maxilla and mandible before installation of titanium fixtures. The results indicate that the CT scan can give information about the structure and bone density. The height and the width of the alveolar osseous crests and the relationship with the incisive canal and the mandibular canal are clearly demonstrated. The CT scan can facilitate the measurement of the space available in order to install the titanium fixtures.
