title: Hospital dentistry and the occurrence of pneumonia

description: ABSTRACT Objective: To determine the oral health conditions of the elderly patients hospitalized and restricted to the bed and to correlate with the development of infections at a distance, especially pneumonia. To verify if the daily follow-up of the dental surgeon improves oral health and reduces the occurrence of respiratory infection in hospitalized elderly patients. Methods: Quasi-experimental study with hospitalized and bed restricted elderly, two simple randomized groups, one group was evaluated and monitored daily by the dental surgeon, the other group was evaluated and received guidance on health care and oral hygiene and of dental prostheses. Results: Both groups presented poor health and oral hygiene and prosthetic conditions. There was improvement in the oral health conditions of both groups. Seven percent of the patients developed pneumonia during the period of hospital stay and the oral health of these patients were considered regular or bad. Conclusion: The performance of the dental surgeon promoted improvements in the oral health of both groups in the first evaluation, with no statistical difference between the group that received daily follow-up and the group that received guidelines, so it was concluded that oral health care should be a behavior of the team multidisciplinary, dentistry should intervene if the changes interfere in the clinical condition of the patient and offer training and support to the multidisciplinary team that is in the first line of care with hospitalized patients.

title: Surgical removal of large mucocele in a young patient: case report

description: ABSTRACT Mucocele is a term applied to the clinical manifestation of phenomena that may affect the minor salivary glands. There are different forms of treatment reported in the literature, including total enucleation. The objective of this study is to describe a surgical technique for removal of Mucocele in a teenage patient. A 16-years-old, female, attended the sector of Pediatric Dentistry of Camilo Castelo Branco University - campus São Paulo / SP. The patient’s main complaint was “a bubble in the mouth that punchs and fills again, feeling salty taste.” At the clinical examination, a circumscribed, mucosa-like, floating-palpation lesion was observed, with a 1.7 cm diameter in the lower lip, with characteristics similar to Mucocele. In the planning of the case, we opted for the surgical removal treatment with anatomopathological analysis. The prognosis for the surgical removal of the lesion was very favorable due to some established criteria: age of the patient, location, depth and size of the lesion.

title: Diagnosis and management of eosinophilic granuloma of the jaw: a case report

description: ABSTRACT The eosinophilic granuloma is the most common form of the Langherans’ cell histiocytosis. In the majority of cases it is represented by a unilocular osteolytic lesion which can occur in adults and children. It is an intraosseous destructive lesion characterized by the presence of vast numbers of eosinophils and histiocytes. It can be localized or multifocal. The tumor is more prevalent in the first two decades of life and tends to affect mandibular body and angle. Most frequent signs and symptoms are pain, swelling, ulceration, gingival necrosis, alveolar bone destruction with mobility and loss of teeth. Therapeutic interventions for this pathology are surgical curettage, local radiotherapy and chemotherapy. This article presents the case of a 9-year old patient who came in for treatment with facial swelling, pain, tooth mobility and intraoral ulcer in the vestibular sulcus of the right mandibular angle region. Imaging and incisional biopsy were obtained. After the histopathological examination confirmed the diagnosis of eosinophilic granuloma, the lesion was removed by curettage and a reconstruction titanium plate was inserted to avoid a pathological fracture. After 14 years of follow-up no recurrence was found and mandibular growth was not impaired. A discussion about this type of tumor is presented, based on the current literature.

title: Photodynamic therapy as an aiding in the endodontic treatment: case report

description: ABSTRACT This article describes the application of Photodynamic Therapy as an aid to the endodontic treatment performed on a permanent tooth iatrogenically perforated and with pulp necrosis. After clinical and radiographic examination, the coronary access, curettage of the drilling area and mechanized preparation with the Reciproc System were performed. The drilling area was sealed with Mineral Trioxide Aggregate after prior alkalinization and decontamination by a calcium hydroxide buffer. After successive intracanal medication changes, the remission of the fistula, a clinical sign of endodontic infection, was not observed. Photodynamic therapy was then performed to reduce bacterial load in the root canal system, which resulted in fistula suppression. Then, it was possible to end the treatment with the obturation of the ducts by the Tagger Hybrid thermomechanical technique. After a year of proservation, the tooth presents no symptomatology and it is concluded that the Photodynamic Therapy was an effective solution in this case.

title: Can the silane heat treatment influence the bond durability between resin cements and a dental ceramic?

description: ABSTRACT Objective Evaluate the influence of silane heat treatment in bond durability between two resin cements and CAD/CAM feldspathic ceramic. Methods 40 feldspathic ceramic blocks were obtained, and were duplicated in microhybrid composite. All ceramic blocks were etched with 10% hydrofluoric acid for 20 s and received application of silane agent. The blocks were randomizedinto eight groups (n=5) according to the surface treatments and luting agents: P- Panavia F; PAg- Panavia F + Aging; HP- Heat Treatment + Panavia F; HPAg- Heat Treatment + Panavia F + Aging; R- RelyX ARC; Rag- RelyX ARC + Aging; HR- Heat Treatment + RelyX ARC; HRAg- Heat Treatment + RelyX ARC + Aging. The heat treatment was performed in furnace at 100 °C for 2 min. All blocks were cemented and cut to obtain samples with adhesive area of 1 mm2. Aging was performed with 10000 thermal cycles. The samples were subjected to microtensile bond strength test. Results The three-way ANOVA test revealed a significant interaction between cement versus heat treatment (p=0.001) and heat treatment versus thermal cycling (p=0.001) indicating that there was a change in bond strength due to surface treatment and aging. Conclusion Therefore, the heat treatment of the silane at 100 ºC for 2 minutes obtained higher values of bond strength between the resin cement and a feldspathic ceramicafter aging.

title: CPP-ACP complexe as an alternative to treatment of incisor molar hypomineralization: case report

description: ABSTRACT The objective of this study was to report the clinical treatment of a child with Incisor Molar Hipomineralization. A 5-year-old Brazilian child, male gender, was diagnosed with Molar Incisor Hypomineralization, reporting high teeth sensitivity. After anamnesis and clinical examination, treatment was conducted with three weekly applications of fluoride varnish containing 5% CPP-ACP complex. Also, it was advice to the patient for using a toothpaste containing fluoride and CPP-ACP (MI Paste Plus). After that, molars with great tooth structure loss were restored with resin modified glass ionomer cement. Prior to the first topical application of varnish with CPP-ACP and fluoride toothpaste containing CPP-ACP, a sensitivity test was conducted using thermal stimulus and facial pain scale. It was observed relative sensitivity decrease between sessions, reporting no sensitivity at the last session before the restoration. The treatment of Molar Incisor Hypomineralization teeth with CPP-ACP complex associated with fluoride varnish can be an alternative to reduce sensivity.

title: Dental age estimation of Jordanian children: applicability of Demirjian method

description: ABSTRACT Objectives: To evaluate the accuracy of Demirjian method in estimating the chronological age of male and female Jordanian children and to establish a new dental age curve if the Demirjian method was not found to be accurate. Methods: Orthopantomograms (OPTs) of 1374 Caucasian Jordanian children (684 females and 690 males) aged 4 to16 years were selected and the dental age was determined by Demirjian method. The chronological ages of the children were obtained by subtracting their birthdates from the date of taking the radiograph. The OPTs were obtained from Archives of Dental Teaching Clinics /XXX and other private orthodontic practices in Irbid and Amman. Results: Demirjian method overestimated chronological age in female and male subjects aged 4 to 8 years. Afterwards, the method underestimated chronological age in females aged 9-11 years and 14-16 years. In male subjects, chronological age was underestimated in subjects aged 9-12 years and 15-16 years. New the dental age curves for Jordanian females and males were constructed. The constants for the quadratic model for the new curves were (b0=-25.341, b1=17.557, b2=-0.623) for females and (b0=-29.809, b1=17.396, b2=-0.595) for males. Conclusion: Demirjian method overestimated the chronological age of Jordanians below the age of 8 years and underestimated the age of Jordanians above 8 years. A new DA standard for Jordanian children was developed and tested for accuracy.

title: Individual biosafety barrier in dentistry: an alternative in times of covid-19. Preliminary study

description: ABSTRACT The return to dental practice in pandemic times is a new challenge due to the generation and dispersion of droplets and aerosols that may contain the SARS-CoV-2 virus, the etiological agent of covid-19. In the last months some droplet and aerosol containment strategies have been circulating on the internet, however, until now there is no evidence in the literature to prove the effectiveness of such barriers. Thus, using a microbial dispersion model with the fast handpiece, the aim of this preliminary study was to compare the dispersion caused by the the dental drill (DD) alone or in association with an individual biosafety barrier (IDBD / DD), which consisted of a layer of PVC film combined to a layer of polypropylene mounted on a frame. The dental drill was activated for one minute having had the water from the reservoir been replaced with a suspension of Lactobacillus casei Shirota. Petri dishes containing MRS agar were positioned at 50, 100 and 150 cm from the headboard of the dental chair at different angles (90 and 0 degrees). At 50 cm, the mean (standard deviation) of L. casei Shirota for DD was 13,554.59 (493.48) CFU, while for IDBD / DD was 570.67 (60.54) CFU (p &lt;0.0001), establishing a 96% reduction. Considering these preliminary results, the individual biosafety barrier proved effective in reducing dispersion from the dental drill in this study model, which suggests that this barrier may be a viable option to optimize biosafety in the dental environment.

title: COVID-19 pandemic impacts to Dentistry

description: ABSTRACT Objective: To achieve a literature review on the impacts of COVID-19 on dentistry. Methods: Analysis of scientific articles contained in the LILACS and PubMed platforms that fulfill the informative purpose of the research. Results: The production of aerosols during dental procedures could be highlighted as the most dangerous agent, the literature recommends restricting the type of service only to emergencies and reducing the use of rotating instruments or cough-inducing equipaments. New protective measures must be taken, such as the type of PPE used and the frequency of asepsis of the workplace, since any surface that has been exposed to oral or pharyngeal secretions may contain a load of viral particles, an online triage is also recommended before any assistance. Due to the easy spreading of this disease and the possibility of asymptomatic patients, the current best measure is avoiding the execution of procediments. Conclusion: COVID-19 will be a milestone for the current generations of health professionals, it could also be an advance for use distance technologies and integration of new biosafety techniques.
