The Dental-BIOfilm Detection TECHnique (D-BioTECH): A Proof of Concept of a Patient-Based Oral Hygiene.

To date, no strong long-term data have been reported about new innovative clinical protocols to manage oral hygiene. An improper management of oral hygiene may lead to an increase in dental implant failure, and to an increase in infective complications in prosthetic rehabilitation. Personalized techniques are strongly required in dentistry and dental hygiene. A customized and personalized approach to oral hygiene is crucial in ensuring not only effective treatment, but also a careful analysis of the general health status of the patient involved in the therapeutic process. D-BioTECH is an acronym for Dental BIOfilm Detection Technique: it is based on a tailored approach to patients, ensuring that the operator actively interacts with the patient and their specific needs, especially during the domiciliary therapy. D-BioTECH is an approach to preventive care: in D-BioTECH, both dental hygienists and dentists play a central role. The use of a personalized approach to oral hygiene is the first step towards increasing implant and prosthesis survival rate; moreover, personalized medicine is strategic for managing and preventing the biological complications associated with several dental risk factors.

Therapeutic efficacy of chlorhexidine-based mouthwashes and its adverse events: Performance-related evaluation of mouthwashes added with Anti-Discoloration System and cetylpyridinium chloride.

OBJECTIVES: To compare 3 mouthwashes: 0.20% chlorhexidine (CHX) with Anti-Discoloration System (ADS), 0.20% CHX and 0.12% CHX with 0.05% cetylpyridinium chloride (CPC), in terms of reduction of plaque and gingival bleeding and side effects. METHODS: Mild gingivitis patients were randomly divided into three Groups: they underwent professional oral hygiene and received instructions: oral rinse with 10 mL for 1', twice a day, 30' after tooth brushing, for 14 days. Primary outcomes were plaque and gingival bleeding, assessed with Plaque Control Record and Gingival Bleeding Index. Feedback questionnaire and spectrophotometer evaluated secondary outcomes: adverse events. Timing of the study was T0 (baseline), T1 (professional oral hygiene) and T2 (14th day after mouthwash use). RESULTS: Sixty-six patients were recruited, two patients dropped out, and 64 patients completed the study. PCR T1-T2 mean variation was 30.67 (SD = 15.22; 95% CI 23.55 to 37.80; P = 0.000), 19.93 (SD = 11.03; 95% CI 14.90 to 24.95; P = 0.000) and 16.24 (SD = 15.35; 95% CI 9.60 to 22.88; P = 0.000) respectively in Groups 0.2% CHX + ADS, 0.2% CHX and 0.12% CHX + CPC. GBI mean variation (T0-T2) was -9.82 (SD = 9.27; 95% CI -5.48 to 14.16; P = 0.000), -19.31 (SD = 11.33; 95% CI -14.15 to -24.47; P = 0.000) and -21.13 (SD = 12.56; 95% CI -15.70 to -26.56; P = 0.000) respectively in Groups 0.2% CHX + ADS, 0.2% CHX and 0.12% CHX + CPC. Statistical significance was found in lower efficacy of 0.2% CHX + ADS Group. Patients tolerated 0.12% CHX + CPC mouthwash better in bleeding perception (95.5%; P = 0.046), burning sensation (13.6%; P = 0.006), and mouthwash taste (100%; P = 0.000). Results on staining were no statistically significant (P = 0.106). CONCLUSIONS: Addition of CPC allows reduction of CHX percentage in mouthwash formulation while keeping equal efficacy and less side effects. ADS addition decreases CHX efficacy in reducing plaque and bleeding, while resulting more tolerated than CHX.

Periodontal Effects of a Transposed Versus a Conventional Flap in Mandibular Third Molar Extractions.

The aim of this study was to compare a transposed with a repositioned flap by assessing the periodontal effects on the second molar and primary healing after extraction of partially impacted lower third molars. A total of 24 patients requiring partially impacted mandibular wisdom tooth removal were enrolled in the study. The test group (n = 12) underwent a transposed flap procedure, whereas the control group (n = 12) underwent a repositioned flap procedure. Plaque index, probing depth, bleeding on probing, and width of keratinized tissue were recorded the day of surgery (T1) and after 60 days (T4). Wound dehiscence was assessed on the mesio-distal and bucco-lingual directions at days 2 (T2), 7 (T3), and T4. No significant differences have been observed in the periodontal parameters between the groups at T1 and T4 (P > 0.05). Similarly, no difference was found at T2, T3, and T4 in wound dehiscence incidence (P > 0.05). To date, no data exists on the use of transposed flaps in third molar surgery; thus a comparison of results cannot be done. Further studies with larger population are needed to investigate the potential advantages of this type of flap.

Evaluation of the esthetic properties of developmental defects of enamel: a spectrophotometric clinical study.

OBJECTIVES: Detailed clinical quantification of optical properties of developmental defect of enamel is possible with spectrophotometric evaluation. Developmental defects of enamel (DDE) are daily encountered in clinical practice. DDE are an alteration in quality and quantity of the enamel, caused by disruption and/or damage to the enamel organ during amelogenesis. METHODS: Several clinical indices have been developed to categorize enamel defects based on their nature, appearance, microscopic features, or cause. A sample of 39 permanent teeth presenting DDE on labial surface was examined using the DDE Modified Index and SpectroShade evaluation. The spectrophotometric approach quantifies L* (luminosity), a* (quantity of green-red), and b* (quantity of blue-yellow) of different DDE. CONCLUSIONS: SpectroShade evaluation of the optical properties of the enamel defect enhances clinical understanding of severity and extent of the defect and characterizes the enamel alteration in terms of color discrepancy and surface characterization.

Parental Knowledge and Its Impact on Nutrition and Oral Health Habits in Children: A Cognitive Investigation.

Background: The correlation between the intake of certain nutrients and the development of oral pathologies has been demonstrated by several studies. The objective of this epidemiological investigation was to evaluate parents' knowledge and awareness of children's nutrition starting from the early stages of childhood. Methods: A questionnaire with 35 questions was handed over to 120 parents of infants aged 4 to 24 months. Among these, 20 questionnaires were excluded because they were incomplete; hence, the final sample analyzed consisted of 100 questionnaires. The outcome of this study revealed that the parents are well aware of many common topics, but their knowledge regarding specific prevention measures, i.e., the use of systemic fluoride as per the international guidelines, needs proper attention. Results: and Conclusions: After analyzing all the collected data, it is possible to conclude that prevention is the best investment to avoid the onset of the carious pathology, which can be possible through parental education, for example, by raising awareness among expectant mothers, through different actions in the territory. However, further research is needed as this study has some limitations and the convenience sample is hospital-based and not effectively representative of the whole population.

Home treatment protocol for dentin hypersensitivity with hydroxyapatite-based biodynamic toothpaste and lactoferrin: a pilot study.

BACKGROUND: In recent years, there has been a gradual increase in cases of dentin hypersensitivity, often related to gingival recession, enamel abrasion from brushing, and wear of root cementum. This condition can affect patients of all ages but is more common between 20 and 40 years of age, especially in females and individuals with periodontal disease. The study aimed to evaluate and compare the efficacy over time of a product for at-home treatment of dentin hypersensitivity. METHODS: One hundred five patients aged between 28 and 65 years were recruited, each with at least two hypersensitive teeth due to erosions, abrasions, gingival recessions, and/or periodontal diseases. Participants were selected through the Schiff Test and anamnestic evaluations, with compilation of periodontal records. Patients are instructed to use the product three times a day, to be applied with a soft-bristled toothbrush and/or topically as a gel on teeth with strong sensitivity and deep cervical lesions and gingival recessions. RESULTS: There were no statistically significant differences between measurements at baseline and after scaling. However, significant differences were observed in follow-ups from the 1st to the 8th week, with a progressive decrease in values. The average trend of product efficacy increases over time according to the Schiff Test, with a significant improvement observed at follow-ups conducted after four and eight weeks. CONCLUSIONS: The results indicate that the product enriched with biomimetic hydroxyapatite and lactoferrin is effective in reducing the painful symptoms of dentin hypersensitivity and in counteracting the inflammatory state of the supporting tissues.

Effect of Different Graft Material Consistencies in the Treatment of Minimal Bone Dehiscence: A Retrospective Pilot Study.

Among different therapeutic strategies proposed in the case of bone volume deficit, guided bone regeneration (GBR) is a consolidated surgical procedure. The objective of this study is to retrospectively evaluate the behavior of two bone grafts with different consistencies in the GBR procedure by measuring the volumetric tissue changes 1 year after surgery. For this retrospective analysis, 25 cases of GBR with simultaneous implant insertion were selected. A total of 13 were grafted with a porcine cortico-cancellous bone mix (CCBM group), and 12 were grafted with a pre-hydrated granulated cortico-cancellous bone mix of porcine origin blended with 20% TSV gel (Collagenated-CCBM). A collagen membrane was fixed to cover the bone defect. A total of 42 implants were placed with computer-guided surgery. Preoperative and 12-month postoperative digital impressions were used to evaluate dimensional changes. Student's t-test used for independent samples showed no statistically significant differences between the integrated distance (p = 0.995) and mean distance (p = 0.734). The mean integrated distance in the CCBM group was 41.80 (SD. 101.18) compared to a mean of 42.04 (SD. 66.71) in the Collagenated-CCBM group. Given the limitations of this study, in patients with peri-implant bone dehiscence, simple heterologous and collagenated heterologous cortico-cancellous bone grafts are suitable for filling the bone defect to promote bone regeneration, although further studies are needed.

Oil Pulling and Polyphenols: Treatment of Gingivitis Patients with 'Itri Extra-Virgin Olive Oil'.

OBJECTIVES: The aim of the study was to evaluate the effectiveness of extra virgin olive (EVO) oil and fruity oil for the treatment of gingivitis. MATERIALS AND METHODS: A sample of 75 patients over 18 years of age with gingivitis induced by plaque bacteria was divided into three groups: study group A, with extra virgin olive oil; study group B, with fruity oil; and control group C. In the two study groups, EVO oil was administered as a mouthwash to patients with gingival inflammation. The protocol included a daily application of the product for 30 days, with three recalls 15 days apart. Clinical parameters of plaque formation and gingivitis, including plaque index (PI) and bleeding index (BI), were assessed at each recall and scored on a specific periodontal chart. The control group received no mouthwash treatment in addition to normal daily oral hygiene procedures, and the same clinical parameters as the study group were evaluated. Data were evaluated using SPSS 27.0 software for Windows (SPSS Inc., Chicago, IL, USA). Then, the pre- and post-treatment values of the groups were compared using Student's t-test, setting p < 0.05 as the significance level. RESULTS: Comparison of the three groups showed that extra-virgin olive oil was an adjuvant in the treatment of gingival inflammation, improving PI and BI. In group A, the mean plaque index showed a 48% reduction, and the bleeding index showed a 64% reduction after 30 days. In group B, the mean plaque index showed a 35% reduction and a bleeding index reduction of 43% after 30 days. CONCLUSIONS: The collected data showed significant improvements in the formation of bacterial plaque and gingivitis. The exact mechanism of such treatment is still to be elucidated. As a result of this, further studies with a different sample of patients than those used and a comparison with other products need to be addressed to verify and demonstrate the antibacterial and anti-inflammatory effects of the components of this natural product.

Impact of Stress on Periodontal Health: Literature Revision.

Stress is a physiological response of the body to stressful life events but may not be when the individual is persistently exposed to the stress trigger, and it negatively affects certain physiological functions, thus triggering psychosomatic diseases. In literature, chronic stress and inadequate coping strategies are found to mediate the risk and development of periodontitis; mechanisms have therefore been proposed to explain the effects of stress on the periodontium. Since stress is a prevalent problem in modern life and given the importance of maintaining oral health, the present literature review aimed to estimate the association between stress and periodontal disease. The research question adopted is the following: "Are psychological stress and periodontal disease related?" The search was conducted in August 2022 and limited to articles in electronic databases from 2017 to 2022 in English, excluding reviews and literature reviews. From the electronic databases, a total of 532 articles were identified and became 306 after reviews and duplicates were removed. An additional bibliographic search was conducted through the same electronic databases, controlled terms and keywords including only systematic reviews, which were previously excluded. Through the bibliography cited in the systematic reviews, an additional 18 articles were identified, with a new total of 324. As a result of reading the title and abstract of these 324 articles, an additional 295 were excluded. Reading the full text of the remaining 29 studies, 2 articles were excluded due to non-adherence to the eligibility criteria. The remaining 27 results were included in our literature review. It has been suggested in the literature that adverse socioeconomic conditions elicit a stress response, which can trigger periodontal inflammation. Most of the 27 articles included in the study confirm and demonstrate a positive association between psychological stress and periodontal disease. Numerous studies have shown the mechanisms through which chronic stress negatively affects periodontal tissues. Therefore, in the light of the results obtained from this review, it is important that oral health professionals, also for general health purposes, consider stress factors among the risk factors of periodontal disease, its severity and decreased efficacy of treatments. It is therefore advisable to act preventively through the interception of chronic stress.

In-vivo colour stability of enamel after ICON® treatment at 6 years of follow-up: A prospective single center study.

OBJECTIVES: This in-vivo clinical study provides subjective and objective documentation on colour stability of enamel after resin infiltration at a mean observation time of six years after treatment. METHODS: 76 teeth previously treated with ICON® due to hypomineralized lesions of enamel were recalled for a follow-up at the 1st Observation Unit of the Department of Oral and Maxillofacial Sciences, "Sapienza" University of Rome (Italy). Colour stability was assessed: i) subjectively by patients using FDI-colour matching criteria; ii) objectively by calculating CIEDE2000 colour differences between the affected/treated and sound enamel in each tooth at T0 (baseline), T1 (one year) and T2 (six years) based on spectrophotometric data. Analysis of correlation between FDI and CIEDE2000 data was performed. RESULTS: Two teeth were lost to follow-up prior to 72 months. No unwanted effects were reported by patients. Number of FDI scores 1 and 2 were 13.5%, 90.6% and 93.2% at T0, T1 and T2, respectively. ΔE00 was evaluated at 6.8 (SD3.8) at T0. ΔE00 was 5.8 (SD3.1) between T0 and T1 and 1.3 (SD0.6) between T1 and T2. ΔE00 reduction (T1-T0) was significantly but only fairly correlated with FDI scores at any follow-up. CONCLUSIONS: This study shows that caries infiltration satisfactorily masks aesthetically relevant lesions after longer follow-up. Subjective and objective outcomes showed a fair correlation mainly for the initial masking effect. CLINICAL SIGNIFICANCE: This prospective clinical trial demonstrates the excellent subjective and objective colorimetric stability of enamel treated with ICON® 6 years after treatment.

Mindfulness as a tool for reducing stress in healthcare professionals: An umbrella review.

BACKGROUND: Health care providers (HCPs) and health care students experience a huge amount of stress due to high workloads and pressure to perform and are likely to develop anxiety, depression and burnout. OBJECTIVE: The objective was to carry out an umbrella review of systematic and narrative reviews on the effectiveness of mindfulness-based interventions in reducing stress and improving well-being in HCPs and health care students. METHODS: Systematic and narrative reviews that examined the impact of mindfulness-based interventions on HCPs and healthcare students' perceived stress were identified through a systematic search of three electronic databases: PubMed, Scopus and Web of Science. RESULTS: Fifteen articles were included in the analysis: eleven systematic and four narrative reviews. Studies' quality varied from critically low to high. The different interventions showed positive results in reducing stress in both HCPs and students, with mindfulness-based stress reduction (MBSR) course having the major impact. CONCLUSIONS: MBSR techniques and other mindfulness based interventions resulted to be potentially effective in reducing stress. However, despite the vast amount of data collected by the studies and the promising results, several limitations affected the validity of the studies. Therefore, more research that considers the critical aspects of this field is required, in order to provide more reliable results.

Characteristics, Diagnosis and Treatment of Compound Odontoma Associated with Impacted Teeth.

Compound odontoma is a malformation typical of young adults below the age of 20, with a slight preference for the male gender and the anterior region of the maxilla. Clinically asymptomatic, it can be detected during a radiological investigation in connection with the persistence of deciduous dental elements and the impaction of definitive ones. The treatment of choice is excisional surgery and recurrence is a rare event. The need for orthodontic therapy for impacted elements is usually not necessary because in most cases, odontomas are small, circumscribed lesions the size of a permanent tooth. In this article, the diagnostic and therapeutic surgical excision procedure is presented in three patients at developmental age with large compound odontomas associated with at least one retained canine, and in two of the cases, with serious transmigration to the impacted tooth elements.

Quality of Life and Stress Management in Healthcare Professionals of a Dental Care Setting at a Teaching Hospital in Rome: Results of a Randomized Controlled Clinical Trial.

In the healthcare environment, more and more people experience work-related stress. The Faculty of Medicine and Dentistry of Sapienza University of Rome, having observed the need to take care of healthcare professionals, has set itself the objective of providing useful tools such as additional and necessary personal protective equipment for healthcare professionals. OBJECTIVE: To promote health through better management, skills, and the use of strategies and solutions to identify, decompress, and neutralize those responsible for work-related stress mechanisms in order to take care of those who care (CURARE CURANTES). MATERIALS AND METHODS: A randomized controlled clinical trial was conducted. The participants were enrolled by three departments of the Department of Dental and Maxillofacial Sciences of Rome; in consideration of emotional involvement of health professionals who work there. A motivational program was offered. RESULTS: There were 17 and 16 healthcare professionals in the intervention and control groups, respectively. Levels of the mental composite score (MCS) varied both in the pre-post phase of the intervention group (p = 0.002), and between the intervention group and control group in the post phase (p = 0.006). No significant differences were observed for the physical composite score (PCS). Similarly, there were no significant differences regarding the positivity scale (PS) and the two dimensions of work-related stress (job demand and decision latitude). CONCLUSION: This study demonstrates the efficacy of yoga training practiced directly in the workplace and wearing work clothes, entering the work context, not weighing further on the healthcare workload, and being a way to carry out physical activity even in those cases in which professionals do not have the time to do it in their free time.

Long-Term Effectiveness of Treating Dentin Hypersensitivity with Bifluorid 10 and Futurabond U: A Split-Mouth Randomized Double-Blind Clinical Trial.

BACKGROUND: The definition of dental hypersensitivity is "pain derived from exposed dentin in response to chemical, thermal tactile or osmotic stimuli which cannot be explained as arising from any other dental defect or disease". One of the treatments proposed is tubular occlusion. The aim of this in vivo split-mouth randomized clinical trial was to evaluate the clinical efficacy of a in-office application of a fluoride varnish (Bifluorid 10) and a bonding resin (Futurabond U) in adults with dentin hypersensitivity. MATERIAL AND METHODS: A total of 180 teeth were treated with Bifluorid 10 and 160 with Futurabond U. Outcome measurements were taken one or two weeks before treatment, at baseline at the application days, at 1 week and at 1-6 months after first treatment. RESULTS: Both treatments reduced pain intensity. Bifluorid 10 and Futurabond U have similar efficacy in reducing SCHIFF-measured pain reduction, while Bifluorid 10 is significantly more efficient for VAS-measured pain reduction, mainly due to long-term pain reduction. Patient age has a significant negative influence on pain reduction, while the influence of patient gender and BEWE of the tooth is insignificant. CONCLUSIONS: Bifluorid 10 and Futurabond U are effective in the treatment of dental hypersensitivity. The RCT was registered at the US National Institutes of Health (ClinicalTrials.gov) #NCT04813848.

Phototherapy and Tailored Brushing Method. Personalized Oral Care in Patients with Facial and Dental Trauma. A Report of a Case.

(1) Background: Traumatic dental injuries are frequent in children and young adults. The facial structures involved in dental trauma may include soft tissues of the face and mouth, bone and dental structures. Dental trauma often results in augmented dental anxiety. Phototherapy can improve stress and pain control thereby improving compliance in young patients with the necessary dental treatments, after dental trauma has occurred. (2) Methods: Phototherapy was performed to enable soft tissue healing. The Tailored Brushing Method (TBM), a personalized approach for at-home oral hygiene procedures, was also utilized, with the aim of improving biofilm control in traumatized patients. (3) Results: The approach hereafter presented made it possible to obtain subjective control of anxiety and pain documented on a visual analog scale (VAS) due to the innovative use of photo-biomodulation. In addition, for the first time, the TBM was adapted to the needs of a patient with facial trauma and illustrated. (4) Conclusions: Phototherapy and TBM were found to be effective in the combined treatment of soft tissue wounds and in the oral care of the traumatized patient.

Facial and Oral Manifestations Following COVID-19 Vaccination: A Survey-Based Study and a First Perspective.

(1) Background: Severe acute respiratory syndrome Coronavirus-2 (SARS-CoV-2) emerged in Wuhan, China, in late 2019. The development of effective and safe vaccines against SARS-CoV-2 has been extremely fast. The list of orofacial adverse effects of BNT162b2 and mRNA-1273 vaccines based on the clinical trials are reported to be rare. The aim of this study was to investigate the facial and oral manifestations of COVID-19 vaccination using a survey-based study. (2) Methods: The questionnaire was developed using Google Forms and sent anonymously to a total of 700 subjects (medical personnel) in Poland, Italy, and other EU countries. (3) Results: 223 people answered the questionnaire, mainly vaccinated with BNT162b2. Only 3.1% and 5.4% experienced oral and facial symptoms, respectively. General diseases presence and age have significant influence on the probability of oral symptoms occurrence after the second dose. Facial symptoms are correlated with general disease; autoimmune pathologies and age, at first and second dose, respectively. Gender, smoking and regular medication intake have significant influence on the probability of taking an absence day. Gender, age, and smoking have a significant influence on the duration of symptoms after second dose. (4) Conclusions: Based on the results of this preliminary survey, there is no observed significant correlation between vaccine administration for COVID-19 and facial and oral manifestations.

In Vivo Imaging-Based Techniques for Early Diagnosis of Oral Potentially Malignant Disorders-Systematic Review and Meta-Analysis.

OBJECTIVES: Oral potentially malignant disorders (OPMDs) are lesions that may undergo malignant transformation to oral cancer. The early diagnosis and surveillance of OPMDs reduce the morbidity and mortality of patients. Diagnostic techniques based on medical images analysis have been developed to diagnose clinical conditions. This systematic review and meta-analysis aimed to evaluate the efficacy of imaging-based techniques compared to the gold standard of histopathology to assess their ability to correctly identify the presence of OPMDs. DESIGN: Literature searches of free text and MeSH terms were performed using MedLine (PubMed), Scopus, Google Scholar, and the Cochrane Library (from 2000 to 30 June 2020). The keywords used in the search strategy were: ("oral screening devices" or "autofluorescence" or "chemiluminescence" or "optical imaging" or "imaging technique") and ("oral dysplasia" or "oral malignant lesions" or "oral precancerosis"). RESULTS: The search strategy identified 1282 potential articles. After analyzing the results and applying the eligibility criteria, the remaining 43 papers were included in the qualitative synthesis, and 34 of these were included in the meta-analysis. CONCLUSIONS: None of the analyzed techniques based on assessing oral images can replace the biopsy. Further studies are needed to explore the role of techniques-based imaging analysis to identify an early noninvasive screening method.

How Did the COVID-19 Pandemic Effect Dental Patients? An Italian Observational Survey Study.

The primary aim of this observational survey study was to assess patients' attitudes toward clinical dental practice during the COVID-19 pandemic; the secondary aim was to evaluate patients' attitudes towards oral health by maintaining an appropriate lifestyle and oral hygiene at home. The questionnaire was developed using Google Forms. The questionnaire consisted of three parts: Part A-geographic, demographic, and personal data; Part B-patients' attitude toward oral health selfcare and lifestyle; Part C-patients' attitude toward dental practice. This survey, conducted during the months of November and December 2020, enrolled 1135 subjects throughout Italy. All data were statistically analyzed. COVID-19 has changed patients' approach to dental procedures. Most of the people interviewed lived in families, and their greatest fear was infecting a family member. Restrictive measures forced people to stay at home, which led to an increased consumption of various types of food, including cariogenic foods. People said they felt safe when they went to the dentist, but they also paid special attention to measures to prevent contagion. Among the measures that should be introduced in similar situations in the future, people wanted telemedicine, a phone recall, and the possible use of video clips for home oral care instructions.

A retrospective cohort study on peri-implant complications in implants up to 10 years of functional loading in periodontally compromised patients.

BACKGROUND: Prevalence of peri-implantitis is directly proportional to the time of functional loading. The aim of this retrospective study was to assess the survival and success rates as well as the incidence of peri-implantitis among patients with a history of periodontitis and among implants with 1 to 10 years of functional loading. METHODS: We evaluated clinical records of periodontally compromised patients treated between January 1998 and July 2002, with implants enrolled in a supportive periodontal and peri-implant treatment follow-up program. The following assessment indexes during follow-up were recorded: suppuration on probing, modified bleeding on probing, probing depth, implant mobility, bone changes, and criteria of success of Albrektsson. RESULTS: Clinical data of 475 patients with 1,991 implants were analyzed for a period of 10 years of functional loading. The survival and success rates were 91.8% and 75.4%, respectively, and the cumulative incidence of peri-implantitis among patients was 24.4%. The survival rate was 96.1%, and the success rate was 83.7% among implants. The incidence of peri-implantitis exhibited a peak rate after the seventh year (2.1%). The prevalence of peri-implantitis increased from 3.2% to 9.7% between 5 and 10 years of follow-up, and the peri-implantitis rate among implants was 12.9% after 10 years of functional loading. CONCLUSION: Peri-implantitis begins to appear more frequently after the fifth year of functional loading, especially between the seventh and eighth years of function.

Diagnostic Drama. Use of ICDAS II and Fluorescence-Based Intraoral Camera in Early Occlusal Caries Detection: A Clinical Study.

BACKGROUND: Early diagnosis of occlusal caries is of paramount importance for a minimally invasive approach in dentistry. The aim of the present in vivo clinical prospective study was to compare the diagnostic outcomes of visual subjective evaluation between the International Caries Detection and Assessment System (ICDAS-II) and an intraoral fluorescence-based camera (VistaCam iX Proof, Dürr Dental, Bietigheim-Bissingen, Germany) for the detection of pits and fissures in early caries lesions of posterior teeth. METHODS: The study included 1011 posterior teeth in 255 patients aged 13-20 years (mean age 16 ± 2.2 years). Two blinded operators evaluated all the occlusal surfaces and the first assigned an ICDAS-II code, while the second assessed the VistaCam score: sound enamel (score 0-1.2); initial enamel decay (score 1.2-1.5); dentine caries (score 1.5-3). RESULTS: Some 283 (28%) of the assessed teeth were ICDAS-II code 0; 334 (33%) code 1; 189 (18.7%) code 2; 176 (17.4%) code 3; and 29 (2.9%) code 4. The level of agreement between the two procedures was expressed by using Cohen's and Fleiss' kappa statistics and performing McNemar's test. VistaCam assessed in 513 (50.7%) sound enamel; in 292 (28.9%) initial enamel decay; and in 206 (20.4%) dentine caries. CONCLUSIONS: This comparative study showed a poor agreement between the two diagnostic methods, especially between ICDAS-II 0, 1 and 2 codes and fluorescence assessments.
