Stage II and stage III periodontitis clinical burdens of HIV-1 undergoing antiretroviral therapy.

OBJECTIVES: The aim of this retrospective cross-sectional study was to estimate the association of HIV-1 infection under highly active antiretroviral treatment (HAART) on the clinical parameters of periodontitis. MATERIALS AND METHODS: A total of 205 patients were divided in two groups: 74 HIV + and 131 HIV - . Periodontal probing depth (PPD), clinical attachment loss (CAL), bleeding on probing (BOP), and visible supragingival biofilm (VSB) were recorded. The association of HIV-1 infection with the presence of at least 3 sites with PPD ≥ 5 mm and/or CAL ≥ 4 mm in non-adjacent teeth was estimated using binary logistic regression models. RESULTS: The variables HIV-1 infection (OR = 5.53, p < 0.0001, 95% CI: 2.45-13.64), age [range 35-50 years old (OR = 5.73, p < 0.0001, 95% CI: 2.49-13.20); > 50 years old (OR = 6.29, p = 0.002, 95% CI: 1.94-20.42)], and VSB (OR = 23.68, p < 0.0001, 95% CI: 8.07-69.53) showed a significant direct association with BOP outcome. CONCLUSIONS: HIV-1 infection under HAART did not have association with the presence of at least 3 sites with PPD ≥ 5 mm and/or CAL ≥ 4 mm. However, HIV patients on HAART had direct association of HIV-1 infection with BOP and an inverse association with PPD. CLINICAL RELEVANCE: These results support that monitoring gingival bleeding associated with oral prophylaxis would be beneficial in the prevention and management of periodontitis in HIV-1 patients on HAART.

Recall Rates of Patients in Endodontic Treatments: A Critical Review.

The number of patients that return for recall appointments has great importance to validate endodontic treatment outcomes. The purpose of this review was to investigate the rate of return on recall and the main factors that influence this rate of return. A literature review was performed in the PubMed database for the years from 1978 to 2017, using the following keywords: recall rate, endodontic treatment, endodontic retreatment, apical surgery. The inclusion criteria were: prospective studies in English, and in vivo research with humans, which included patient return rates. A total of 35 studies that fulfilled the established criteria were selected. The percentage of patients who returned on recall was 56%. More female patients (60%) attended the recall appointments than male (40%). The three main reasons for not returning were: patients did not observe the follow-up appointment (490), not returning due to a lack of interest (99) and changing their address (222). The age of the patients attending the appointments varied from 28.6 to 62 years old, with the highest percentage of patients that returned ranging from 40 to 52.5 years old. According to the literature the optimal rate of return for follow-up treatment should be greater than 80%, for the validity of the research. However, the reality presented in the studies is far from ideal. Many studies do not even mention these rates of return in their methodologies or in their results, which may mask the true treatment success rates.

An unusual osteoma in the mandibular condyle and the successful replacement of the temporomandibular joint with a custom-made prosthesis: a case report.

BACKGROUND: An osteoma is a benign tumor of bone with unknown etiology and is considered rare, mostly restricted to the craniofacial skeleton. CASE PRESENTATION: This case report describes an uncommon condylar osteoma in a 67 years old white female patient with laterognathism to the left side, limited mouth opening, aesthetic change and pain associated with the right temporomandibular joint (TMJ). The histopathological examination confirmed osteoma. The lesion was surgically excised and immediate reconstruction was carried out using a custom-made total TMJ prosthesis. The patient has been in follow-up for 2 years, with no symptoms. CONCLUSIONS: Unilateral total TMJ prosthesis can be considered to replacement of TMJ after osteoma excision with resection of the condyle.

Extrusive, Intrusive Luxation and Avulsion in a 7-Year- Old Child: One year of Clinical, Radiographic and Tomographic Follow-Up

ABSTRACT: Dental trauma is a serious injury that occurs frequently in children and adolescents, requiring urgent dental care. The upper central incisors are the most vulnerable teeth to such traumatic injuries, which can lead to bite restrictions, difficulties in phonation and esthetical questions. The aim of this study was to report the success of a conserva tive approach carried out on a 7-year-old patient, victim of multiple dental trauma, involving permanent and deciduous teeth. The male patient fell from his own height, causing soft tissue lacerations and dento-alveolar traumatism in both deciduous and permanent teeth. Complementary examinations (periapical radiographs and computed tomography) were carried out. Based on the diagnoses the patient was referred to specialists for appropriate treatment. The present report highlights the importanc e of an early diagnosis, suitable treatment and follow-up of patients after an alveoli-dental trauma and shows the direct relationship of this approach with the prognosis of the patient and the tooth.

RESUMEN: El trauma dentario es una lesión grave que ocurre con frecuencia en niños y adolescentes y requiere atención dental urgente. Los incisivos centrales superiores son las piezas dentarias más vulnerables a dichos traumas, pudiendo generar restricciones en la mordida, la fonación y a nivel estético. El objetivo de este estudio fue reportar el éxito de un enfoque conservador llevado a cabo en un niño de 7 años de edad, víctima de un trauma dentario múltiple, que involucró tanto dientes temporales como permanentes. El paciente masculino, cayó desde su propia altura, causando laceraciones en los tejidos blandos y traumatismo dento- alveolar en piezas de ambas denticiones. Se llevaron a cabo exámenes complementarios (radiografías periapicales y tomografía computarizada). Basado en el diagnóstico, el paciente fue referido a especialistas para realizar el tratamiento apropiado. El presente reporte destaca la importancia de un diagnóstico precoz, un tratamiento adecuado y el seguimiento de los pacientes luego de un trauma dento-alveolar, y cómo este enfoque muestra relación directa con el pronóstico del paciente y del diente.

Clinical signs and bacterial communities of deciduous necrotic root canals detected by PCR-DGGE analysis: research association.

OBJECTIVE: This study sought to investigate the possible association between clinical and radiographic data of the patients with the bacterial community profiles involved in cases of necrosis in primary root canals. METHODS: Microbial community profiles for 25 samples from necrotic deciduous root canals were analyzed using the polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE) fingerprinting approach. These results were related to the clinical and radiographic data of these patients. RESULTS: The analysis showed a large diversity of microbial communities in necrotic deciduous root canals. The statistical results pointed out that posterior and anterior teeth were associated with <20 bands and >20 bands in PCR-DGGE method, respectively. A relationship was verified between ages >4 years old and posterior teeth and, ages ≤4 years old and anterior teeth. CONCLUSIONS: The data showed a polymicrobial community and pointed out the association of age with necrosis in anterior and posterior teeth.

Periradicular lesions in HIV-infected patients attending the faculty of dentistry: clinical findings, socio-demographics status, habits and laboratory data - seeking an association

OBJECTIVE: The purpose of this study was to estimate the prevalence of periradicular lesions in HIV-infected Brazilian patients and to assess the correlation of several factors with the periradicular status. METHOD: One hundred full-mouth periapical radiographs were evaluated. A total of 2,214 teeth were evaluated for the presence of periradicular lesions, caries lesions, coronal restorations, pulp cavity exposure and endodontic treatment. RESULTS: The prevalence of periradicular lesions was 46%. There were no significant differences between individuals with or without periradicular lesions with respect to their socio-demographic status, habits, laboratory data and route of HIV infection. However, the presence of a periradicular lesion was statistically correlated with the number of teeth with endodontic treatment (p = 0.018), inadequate endodontic treatment (p = 0.025), images suggesting pulp cavity exposure (p = 0.002) and caries lesions (p = 0.001). CONCLUSIONS: The prevalence of periradicular lesions in HIV-infected individuals was 46% and was not related to HIV infection. .
