Decayed, missing and filled teeth index and dental anomalies in long-term survivors leukaemic children: a prospective controlled study

Objective: The aim of this prospective controlled study is the comparison between long-term children survived leukaemia and a control group in terms of the decayed, missing or filled permanent teeth (DMFT) and dental anomalies. Study design: Fifty-two long term children survived leukaemia, aged from 8 to 15 years (27 females, 25 males; mean age 11.5 years) were evaluated for the possible effects of the anti-leukaemic therapy on dental development and compared to a control group of 52 healthy children (27 females, 25 males, mean age 11 years). All long-term children who survived were at least 24 months in continuous complete remission. The study of the dental status with a routine oral examination and panoramic radiographs was performed. The DMFT (recorded according to the WHO criteria) and dental anomalies were registered and evaluated. Results: The results of this study evidence that long-term children survived leukaemia, in comparison with the control group, have an higher risk to develop dental caries and show a greater severity of dental anomalies including V-shaped roots, dental agenesis, microdontia, enamel dysplasias. Conclusions: Paediatric patients with haemathological diseases require a special attentions in dental care in addition to the antineoplastic treatment. Therefore, oral hygiene and oral health can be maintained thanks to a close cooperation between the paediatric oncohaematologists, pediatrics dental surgeons and dental hygienists

Aging and oral care: An observational study of characteristics and prevalence of oral diseases in an Italian cohort

Background: Poor oral health is a common condition in patients suffering from dementia. Several aspects of this systemic pathology contribute to causing oral problems: cognitive impairment, behavior disorders, communication and, motor skills deterioration, low levels of cooperation and medical-nursing staff incompetency in the dental field. Objectives: The objectives of this study were to evaluate the prevalence and the characteristics of oral pathology in a demented elderly population, as well as to check the association between the different degree of dementia and the oral health condition of each patient. Materials and Methods: In this observational study (with cross-sectional design) two groups of elderly patients suffering from dementia, living in two different residential care institutions were recruited. The diagnosis of dementia of each included patient was performed using the Clinical Dementia Rating Scale. In order to evaluate the oral health condition of the included subjects, each patient underwent a physical examination of the oral cavity, during which different clinical parameters were analyzed (number of remaining teeth, oral mucosa, periodontal tissues, bone crests). To each parameter, a score was assigned. Spearman’s Rho test was used. Results: Regarding the prevalence of oral pathology in elderly suffering from dementia, it emerged that 20.58% of the included patients had mucosal lesions and/or new mucosal formations (in most cases undiagnosed and therefore untreated). The prevalence of periodontal disease was equal to 82.35% and a marked clinically detectable reabsorption of bone crests was found in almost all patients (88.23%). 24.13% of patients, who underwent the oral examination, had totally edentulous maxillae and/or with retained roots, without prosthetic rehabilitations. The correlation index r showed the presence of a linear correlation (inverse relationship) between the degree of dementia and the state of health of the oral cavity of each patient. Conclusions: Several factors contribute to poor oral health in the elderly suffering from dementia: cognitive functions deterioration, behavioral disorders and inadequate medical-staff nursing training on oral hygiene. This study also demonstrated that the lower the dementia degree is, the lower tends to be the oral health status. In order to guarantee a complete assistance to these patients, residential care institutions should include in their healthcare program specific dental protocols

Clinical Management of Oral Lichen Planus: A Systematic Review

Aim: The clinical management of OLP represents a considerable challenge for the oral physician. The aim of this review is to assess the main intervention used in the management of OLP and the efficacy of every type of treatment.Materials and Methods: We searched and analyzed PubMed database for articles on OLP management. Only randomized controlled trials, comparing an active treatment with placebo, or between different active treatments, were considered in this systematic review. Only patients with symptomatic OLP were included and interventions of all types were considered (topical treatment, systemic drugs, non pharmacological intervention).Results: A total of 25 randomized controlled trials were examined and included in this review. Steroids are the most frequently employed drug in the treatment of OLP and their efficacy and safety are demonstrated. Also calcineurin inhibitors and photo-dynamic therapy are used in different studies for OLP management, with positive results.Conclusion: Topical steroids remain the first-line treatment for symptomatic OLP, however, many different pharmacological and non-pharmacological therapies would represent a valid alternative for its management, but, nowadays they require further investigations

Successful Rehabilitation of Partial Edentulous Maxilla and Mandible with New Type of Implants: Molecular Precision Implants

The extraction of teeth results in rapid bone resorption both vertically and horizontally in the first month. The loss of alveolar ridge reduces the chance of implant rehabilitation. Atraumatic extraction, implant placement in extraction socket, and an immediate prosthesis have been proposed as alternative therapies to maintain the volume and contours tissue and reduce time and cost of treatment. The immediate load of implants is a universally practiced procedure; nevertheless a successful procedure requires expertise in both the clinical and the reconstructive stages using a solid implant system. Excellent primary stability and high bone-implant contact are only minimal requirements for any type of implant procedure. In this paper we present a case report using a new type of implants. The new type of implants, due to its sophisticated control system of production, provides to the implantologist a safe and reliable implant, with a macromorphology designed to ensure a close contact with the surrounding bone

Oral Health in Migrants: An Observational Study on the Oral Health Status of a Migrant Cohort Coming from Middle-and Low-Income Countries

Introduction. The oral health conditions of migrants coming from middle-and low-income countries to developed countries have been shown to be poorer than those of the host population. Since the phenomenon of migration has continued to grow over the past five decades, the oral health status of migrant populations should be an issue of great concern. Objectives. The objective of our observational study was to analyse the periodontal health status and the prevalence of dental caries and lesions of the oral mucosa in a migrant cohort resident in Italy, assessing the association between the oral health status and the educational level of the included patients. Materials and Methods. Our research was conducted at the dental department of Policlinico Tor Vergata (Rome, Italy). A sample of 200 migrants coming from middle-and low-income countries, aged between 3 and 37, was included in our study. Each patient underwent a physical examination of the oral cavity, recording the DMFT/dmft index, Community Periodontal Index of Treatment Needs (CPI), and lesions of the oral mucosa. The one-way ANOVA test was used to establish the correlation between the oral health status and the educational level of the participants. Results. Many participants (62.5%) showed a DMFT/dmft Index ≥ 4; only 27% of the migrants had a DMFT/dmft Index lower than 4, and only 21 of them (10.5%) were recorded at 0. A CPI equal to 0 or 1 was observed in 131 patients (65.5%), while only 30 participants presented a CPI equal to or higher than 4 (15%), and 19.5% (39 patients) were assigned to code 2 and 3. Significant statistical differences were found in the CPI after adjusting data for the educational level of the included participants (p-value < 0.01). Conclusions. The data obtained in our research highlighted poor oral conditions among the analysed migrant population, recording a high prevalence of dental caries and inadequate oral hygiene habits

Polymerization shrinkage and spherical glass mega fillers: Effects on cuspal deflection

Purpose. The Authors analyzed the effect of spherical glass mega fillers (SGMF) on reducing contraction stress in dental composite resins, by means of a cavity model simulating the cuspal deflection which occurs on filled tooth cavity walls in clinical condition. Materials and methods. 20 stylized MOD cavities (C-factor = 0.83) were performed in acrylic resin. The inner surface of each cavity was sand blasted and adhesively treated in order to ensure a valid bond with the composite resin. Three different diameter of SGMF were used (i.e. 1, 1,5, 2 mm). The samples were divided in 4 groups of 5 each: Group 1 samples filled with the composite only; Group 2 samples filled with composite added with SGMFs, Ø1mm (16 spheres for each sample); Group 3 samples filled with composite added with SGMFs, Ø1,5 mm (5 spheres for each sample); Group 4 samples filled with composite added with SGMFs, Ø2 mm (2 spheres for each sample). Digital pictures were taken, in standardized settings, before and immediately after the polymerization of the composite material, placed into the cavities. With a digital image analysis software the distances from the coronal reference points of the cavity walls were measured. Then the difference between the first and second measurement was calculated. The data were analyzed by means of the ANOVA test. Results. A significative reduction on cavity walls deflection, when the composite resin is used in addiction with the SGMFs was observed. The SGMFs of smallest diameter (1mm) showed the better outcome. Conclusion. The SGMFs are reliable in reducing contraction stress in dental composite resins

Biology of Drug-Induced Gingival Hyperplasia: In Vitro Study of the Effect of Nifedipine on Human Fibroblasts

Background: It has been proven that the antihypertensive agent nifedipine can cause gingival overgrowth as a side effect. The aim of this study was to analyze the effects of pharmacological treatment with nifedipine on human gingival fibroblasts activity, investigating the possible pathogenetic mechanisms that lead to the onset of gingival enlargement. Methods: The expression profile of 57 genes belonging to the “Extracellular Matrix and Adhesion Molecules” pathway, fibroblasts’ viability at different drug concentrations, and E-cadherin levels in treated fibroblasts were assessed using real-time Polymerase Chain Reaction, PrestoBlue™ cell viability test, and an enzyme-linked immunoassay (ELISA), respectively. Results: Metalloproteinase 24 and 8 (MMP24, MMP8) showed significant upregulation in treated cells with respect to the control group, and cell adhesion gene CDH1 (E-cadherin) levels were recorded as increased in treated fibroblasts using both real-time PCR and ELISA. Downregulation was observed for transmembrane receptors ITGA6 and ITGB4, the basement membrane constituent LAMA1 and LAMB1, and the extracellular matrix protease MMP11, MMP16, and MMP26. Conclusions: The obtained data suggested that the pathogenesis of nifedipine-induced gingival overgrowth is characterized by an excessive accumulation of collagen due to the inhibition of collagen intracellular and extracellular degradation pathways

Measurement of Oral Epithelial Thickness by Optical Coherence Tomography

Optical coherence tomography (OCT) is a real-time, in-situ, non-invasive imaging device that is able to perform a cross-sectional evaluation of tissue microstructure based on the specific intensity of back-scattered and reflected light. The aim of the present study was to define normal values of epithelial thickness within the oral cavity. OCT measurements of epithelial thickness were performed in 28 healthy patients at six different locations within the oral cavity. Image analysis was performed using Image J 1.52 software. The healthy epithelium has a mean thickness of 335.59 ± 150.73 µm. According to its location within the oral cavity, the epithelium showed highest values in the region of the buccal mucosa (659.79 µm) and the thinnest one was observed in the mouth’s floor (100.07 µm). OCT has been shown to be useful for the evaluation of oral mucosa in vivo and in real time. Our study provides reference values for the epithelial thickness of multiple sites within the oral cavity. Knowledge of the thickness values of healthy mucosa is, therefore, of fundamental importance
