    This study compared fluoride levels in commercially available black, green, and matcha teas. All teas had some fluoride content, but the values differed significantly among all of the brands and types. Drinking tea could aid caries prevention but may increase the risk of fluorosis if consumed to excess.

  • Oral Medicine, Oral Diagnosis, Oral Pathology An unusual case of oral phleboliths without evidence of associated vascular anomalies

    João Adolfo Costa Hanemann

    This case report describes the discovery of noncalcified phleboliths that were not associated with any vascular anomalies, which is an unusual presentation. The finding of negligible calcium in the recently developed lesions suggests that the calcification process of phleboliths is relatively slow.

    When the outcomes of a pediatric dentistry training initiative for general dentists were evaluated, participants reported an increase in the number of children treated and the scope of services they provided. Training initiatives seeking to enhance the clinical skills and knowledge of general dentists may be an effective tool for increasing access to care for children.

  • Prosthodontics Comparison of different methods for obtaining centric relation: a systematic review

    A systematic review of the literature was conducted to verify which technique generates the greatest reproducibility of the centric relation. Based on the guided methods and swallowing technique, it is not possible to conclude which technique can generate the greatest reproducibility of the centric relation. However, analysis suggests that in most cases intraoral gothic arch tracing is superior or equivalent to guided methods.

    Evaluation of the cone beam computed tomograms of 90 patients revealed that chewing-side preference does not influence the volume of the mandibular condyle or coronoid process or the dynamic parameters of the temporomandibular joint.

    The erosive potential of powdered juice drinks on dental enamel was evaluated in 2 stages: physicochemical characterization and erosive challenge testing. In stage 1, the pH and titratable acidity of powdered juices were analyzed. In stage 2, the erosive effect of 5 juices was tested using a pH cycling model and bovine dental enamel blocks. The results demonstrated that commercially available powdered juice drinks, especially lemon juice, present erosive potential and lead to surface loss of dental enamel.

    Jose Obed Garcia-Cortes

    This systematic review examined the literature regarding the outcomes of endodontic treatment vs extraction and implant-assisted replacement. Meta-analyses revealed that both treatments had similar outcomes, with endodontic therapy proving slightly better when survival rates were considered as failure rates.

  • Periodontics Contemporary minimally invasive VISTA approach for gingival recession coverage: a case series

    Rajendran Poornima 
    Anand Meena

    In this case series, the vestibular incision subperiosteal tunnel access (VISTA) technique was used, without additional grafting, to treat Class I or II gingival recession at 28 sites in 10 patients. The posttreatment clinical attachment level, Gingival Index, width of attached gingiva, and height of gingival recession improved significantly compared to baseline. The mean percentage of root coverage achieved was 78.99%, and 19 sites showed 100.0% root coverage.

  • Special Care Dentistry Medical comorbidities associated with autism spectrum disorder and their impact on dental care

    Evan Spivack

    Individuals with autism spectrum disorder, a neurodevelopmental disorder affecting communication, behavior, and socialization, often present with multiple medical comorbidities that affect dental treatment. This article reviews the most common of these neurologic, psychiatric, and gastrointestinal issues and explores their relevance to dental care.

  • Pediatric Dentistry Impact of social media on the oral hygiene habits of children and adolescents: a randomized controlled clinical trial

    Sabrina Natasha Digiacomo Sarwer-Foner

    Ricardo de Sousa Vieira

    This study compared the impact of conventional and digital education approaches on the oral hygiene outcomes and habits of children and adolescents. Students were randomly allocated to the control group, which received conventional oral health education, or the experimental group, which received both conventional education and digital oral health content through WhatsApp Messenger. Both groups presented a 30% reduction in PI after the educational interventions, but the experimental group flossed significantly more frequently than the control group. The smartphone app seemed to be an effective auxiliary resource for providing oral health education.
