    In this case report the author illustrates a protocol for post-extraction fullarch rehabilitation produced with the use of computerized virtual treatment planning and guided surgery. In a 74-year old man presenting a failed maxillary attachment-retained removable partial denture, a treatment plan focused on the immediate loading of a post-extraction full-arch prosthesis was developed. Starting from prosthetic analysis a modular scan template for CBCT examination was designed, with a 3D simulation software a protocol for guided implants placement and prosthetic rehabilitation was setup. With the support of this procedure, the author performed the extraction of eight teeth, the placement of eight implants (including extraction sites) with flapless approach, and the immediate load of a provisional screw retained prosthesis. At one year follow-up clinical and radiographic results were stable. In selected cases, this protocol may offer significant advantages, including one-day treatment, reduced post-surgical discomfort and immediate improvement in function and aesthetics

    Aim This study is a statistical retrospective analysis on the correlation between intake of systemic fluoride, oral hygiene conditions and frequency of dental caries in primary and permanent dentitions in a sample of pediatric subjects. The aim of our study was to evaluate in a sample of patients how the caries index (dmft and DMFT) could vary according to the assumption of systemic fluoride supplements, the oral hygiene condition (measured with the Oral Hygiene Index - OHI-S) and the age of the first pediatric dentistry visit. Materials and methods The study is based on the analysis of a sample of 1000 subjects (500 males and 500 females), aged between 3 and 14 years old (mean 9.3) conducted in the division of Pediatric Dentistry at the University of Rome Tor Vergata. Results Caries frequency in primary teeth is not significantly influenced by patient gender, fluoride intake and duration of fluoride intake; it is significantly influenced by the age of the first pediatric dentistry visit (p<0.001) and Oral Hygiene Index (p<0.001). Caries frequency in permanent teeth is not significantly influenced by patient gender (p>0.1), duration of fluoride intake (p>0.1), it is significantly influenced by age of the first pediatric dentistry visit (p<0.001) and Oral Hygiene Index (p<0.001). We found a positive correlation between number of deciduous teeth decayed and permanent teeth decayed (p<0.0001). Conclusion This study does not support the hypothesis that systemic fluoride intake may reduce the prevalence of caries in deciduous and permanent teeth. A high Oral Hygiene Index and early age of the first pediatric dental examination seem to have a positive effect on reducing the prevalence of tooth decay

    Preserving periodontal soft tissues (ST) is crucial to ensure long-term stability of dental health. Gingival recession (GR) can lead to both functional and aesthetic challenges, often necessitating surgical solutions. Techniques such as the coronally advanced flap (CAF), either alone or combined with grafts, have been documented as practical approaches. However, a significant drawback of autogenous grafts is the harvesting process, which extends the healing time at the donor site and increases patient discomfort. This study aims to evaluate the most reliable methods for addressing graft rejection (GR) using cellular allografts (CAF) along with a novel xenogeneic acellular dermal matrix (xeno-ADM), providing insight and guidance for clinicians in their decision-making process. A literature review was conducted from March to June 2020, using PubMed, the Cochrane Library, and manual searches of key journals, including the Journal of Periodontology, International Journal of Periodontics and Restorative Dentistry, Journal of Clinical Periodontology, and Journal of Periodontal Research. The investigation explored GR classification systems, surgical flap designs for root coverage procedures (RCP), and the graft types used in these interventions. All reviewed RCP techniques demonstrated reductions in recession depth (RD) and gains in clinical attachment level (CAL), making them viable for clinical use. Both CAF and tunnelling techniques are skill-intensive and require practice to achieve full root coverage. Xeno-ADM (NovoMatrix) emerges as a promising substitute for subepithelial connective tissue grafts (SCTG), offering ease of use, unlimited availability, reduced postoperative morbidity, rapid vascularization, and excellent tissue integration. However, additional research is warranted to assess its longterm stability at least one year after surgery

    Obiettivi Il morbo di Riga-Fede (MRF) è una condizione patologica benigna del bambino caratterizzata da lesioni ulcerose a carico di lingua, muco­sa geniena, gengive o pavimento della lingua, causate più frequen­temente dall’azione traumatica di denti natali/neonatali. La sintoma­tologia dolorosa può essere as­sente o acuta, fino a impedire al bambino di alimentarsi. Scopo del lavoro è una revisione della letteratura sulle possibilità di cura proposte per MRF e la de­scrizione di due casi clinici con di­verso approccio terapeutico. Materiali e metodi È stata condotta una revisione si­stematica della letteratura ri­guardo il trattamento del morbo di Riga-Fede associato a denti natali e neonatali. È stata eseguita una ricerca sui database PubMed, Scopus e Goo­gle Scholar aggiornata al 1° aprile 2020. Per compilare la revisione sistematica è stato eseguito il pro­tocollo PRISMA (Preferred Repor­ting Items for Systematic Reviews and Meta-Analysis). Tutti i casi clinici descritti in lette­ratura identificati sono stati cata­logati per età, sesso, presenza di elementi natali o neonatali, sede della lesione, complicanze clini­che, trattamento e tempi di gua­rigione. Risultati Negli studi revisionati, sono stati oggetto di osservazione e di piano terapeutico 44 casi clinici. I tratta­menti descritti sono stati: estrazio­ne dentale (41,3%), ameloplastica (14,3%), restauro additivo dei margini incisali (7,5%), biopsia escissionale (7,5%), utilizzo di placche occlusali (2,9%), applica­zione topica di corticosteroidi (9,7%), lidocaina gel 2% (5,2%), piante acantacee (2,9%), fluoro (2,9%), acqua ossigenata (2,9%) e low level laser therapy (2,9%). Discussione e conclusioni L’avulsione dentaria e l’amelopla­stica sono i due trattamenti elettivi per il morbo di Riga-Fede. L’estrazione è indicata nel caso in cui il bambino non è in grado di alimentarsi a causa della sintoma­tologia dolorosa o quando vi è un alto di rischio di ingestione/inala­zione degli elementi presenti a causa dell’elevata mobilità. L’ameloplastica è indicata invece nei casi in cui la mobilità degli elementi presenti non è tale da presentare il rischio di ingestio­ne/inalazione. Il restauro additivo dei margini in­cisali e l’applicazione di una placca occlusale sono due tratta­menti proposti in letteratura ma difficilmente attuabili data l’età neonatale. In associazione a tali trattamenti sono state proposte applicazioni topiche a base di corticosteroidi e l’utilizzo di laser a diodi al fine di ridurre la componente algica e infiammatoria. Implicazioni cliniche Il presente studio indirizza il clinico verso la scelta terapeutica più in­dicata, alla luce dell’ottimizzazio­ne del risultato finale.OBJECTIVES Riga-Fede disease (MRF) is a be-nign pathological condition of the child characterized by ulcerative lesions of the tongue, buccal mucosa, gum or floor of the tongue, most frequently caused by the traumatic action of natal/neonatal teeth. Painful symptoms can be absent or acute, until the child is prevented from feeding. The purpose of the work is a literature review of the proposed treatment possibilities for MRF and the description of two clinical cases with a different therapeutic approach. MATERIALS AND METHODS A systematic review of the litera-ture was conducted regarding the treatment of Riga-Fede disease associated with natal and neonatal teeth. A search was performed on the PubMed, Scopus, and Google Scholar databases as of April 1, 2020. The PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analysis) protocol was used to compile the systematic review. All clinical cases described in the identified literature, have been catalogued by age, gender, presence of natal or neonatal elements, location of the injury, clinical complications, treatment and healing times. RESULTS In the revised studies, 44 clinical cases were observed and treated. The treatments described were: dental extraction (41.3%), ameloplasty (14.3%), additive restoration (7.5%), excisional biopsy (7.5%), use of bite (2.9%), topical application of cortico-steroids (9.7%), lidocaine gel 2% (5.2%), acantaceous plants (2.9%), fluorine (2.9%), oxygenated water (2.9%) low level laser therapy (2.9%). DISCUSSION AND CONCLUSIONS Dental avulsion and ameloplasty are the two elective treatments for Riga-Fede disease. Extraction is indicated in the case where the child is unable to feed due to painful symptoms or when there is a high risk of ingestion/inhalation of the elements present due to high mobility. Ameloplasty is indicated in cases where the mobility of the teeth does not cause risk of inges-tion or inhalation. The additive restoration of the in-cisive margins and the application of a bite are two treatments pro-posed in the literature but difficult to implement because of the neonatal age. In combination with these treatments, topical applications of corticosteroids-based solutions and the use of diode lasers have been proposed in order to reduce the algic and inflammatory component. CLINICAL SIGNIFICANCE This study directs the clinician towards the most suitable therapeutic choice, in light of the optimization of the final result
