Advanced peri-implantitis treatment is a clinical challenge. Reconstructive surgery is not suggested in defects with limited bony walls and/or in those with a suprabony defect. All studies of peri-implantitis reconstructive surgery have considered a marginal surgical approach. However, in the present case report, a new apical approach is presented for the reconstruction of an advanced peri-implantitis lesion.First, a non-surgical phase combines prosthetic, mechanical, and chemical strategies. Second, a surgical phase combines the apical nonincised papillae surgical approach (NIPSA) with biomaterials and a connective tissue graft.Successful results have been obtained when using a NIPSA for the treatment of peri-implantitis, despite the unfavorable characteristics of the peri-implant defect.

Cancers have a highly negative impact on the quality of life of paediatric patients and require an individualised oral treatment program for the phases of the disease. The aim of this study was to update existing research on oral care in children diagnosed with cancer. We carried out a literature search (in English, Spanish and Portuguese) in the Pubmed, Cochrane Library, EBSCO, WOS, SciELO, Lilacs, ProQuest, and SCOPUS databases and the websites of hospitals that treat childhood cancers. We found 114 articles and two hospital protocols. After review, we describe the interventions necessary to maintain oral health in children with cancer, divided into: phase I, before initiation of cancer treatment (review of medical record and oral history, planning of preventive strategies and dental treatments); phase II, from initiation of chemo-radiotherapy to 30–45 days post-therapy (maintenance of oral hygiene, reinforcement of parent/patient education in oral care, prevention and treatment of complications derived from cancer treatment); phase III, from 1 year to lifetime (periodic check-ups, maintenance, and reinforcement of oral hygiene, dental treatments, symptomatic care of the effects of long-term cancer treatment). The use of standardised protocols can avoid or minimise oral cancer complications and the side effects of cancer therapies.

Background: Early Childhood Caries (ECC) is a prevalent chronic pathology, and it has a negative impact on the oral and general health of the child patient. Aim: To evaluate the knowledge, attitudes and practices of Spanish paediatricians regarding early childhood caries according to the professional’s years of experience. Material and Methods: A cross-sectional questionnaire was conducted by Spanish paediatricians via WhatsApp and e-mails from January to April 2021. Data were analysed using Chi-squared test, Fisher’s exact test and Cramer’s V test. Results: There were a total of 359 participants. Most respondents were women (81.3%) with up to 10 years of professional experience (31.2%) in primary health care and public health. In most cases, participants had an excellent knowledge of primary dentition (90.8%), but they ignored (56%) when the first visit to the dentist should occur. Regarding the aetiological factors of caries, oral hygiene and prevention, a lower rate of knowledge was observed. The majority of participants (80.8%) were not able to identify white spot lesions and enamel defects (76%). They considered that their knowledge in oral health was deficient, highlighting the need to increase their training. Less experienced paediatricians were found to have higher success rates. Conclusions: The level of knowledge and attitudes regarding early childhood caries of the evaluated paediatricians should be improved. Paediatricians had difficulties in identifying early caries lesions and enamel defects. Nevertheless, a higher level of knowledge and positive attitudes towards dental caries has been detected among paediatricians with fewer years of professional experience.

The use of fluoridated toothpastes is considered the most rational method in dental caries control, and it is recommended for all ages people, but for this they must be established at a minimum concentration of 1,000 ppm of total soluble fluoride, in pediatric patients. The objective of the study was to determine the concentration of total and soluble fluoride present in toothpastes marketed in Spain for pediatric use.A descriptive and cross-sectional study was carried out throughout 2019, analyzing 11 toothpastes for pediatric use marketed in Murcia, Spain. The concentration of fluoride (ppm F=mg F/Kg) total (FT), soluble (FTS) and fluoride ion (F) and MFP (FPOAmong the analyzed toothpastes, 45% contained NaF (sodium fluoride), 45% MFP (sodium monofluorophosphate) and 10% both types of salts. The abrasive used was silica. 98% of the analyzed toothpastes showed total fluoride contents similar to those described by the manufacturer, only 3 toothpastes had fluoride concentrations lower than those described. The range obtained from FT oscillated between 398 -1,474.6 ppm F, and 100% of the toothpastes did not show differences between values of total fluoride and soluble fluoride.Most of the analyzed toothpastes contain a concentration of soluble fluoride between 1,000-1,500 ppm Fluoride, corresponding to the values described by the manufacturers However, there are still toothpastes with values lower than those recommended, minimum 1,000 ppm F, that do not allow effective anticaries activity from a public health point of view.El uso de pastas dentales fluoradas es considerado el método más racional en el control de caries dental, y es recomendado para personas de todas las edades, pero para ello han de establecerse en una concentración mínima de 1.000 ppm de fluoruro total soluble, en pacientes pediátricos. El objetivo del estudio fué determinar la concentración de fluoruro total y soluble presente en pastas dentales comercializadas en España para uso pediátrico.Se realizó un estudio descriptivo y transversal durante el año 2019, analizando 11 pastas dentales de uso pediátrico comercializadas en Murcia, España. Se analizó la concentración de fluoruro (ppm F=mg F/kg) total (FT), soluble (FTS) e ión de Flúor (F) y de MFP (FPOEntre las pastas dentales analizadas, el 45% contenían NaF (fluoruro sódico), 45% MFP (monofluorofosfato de sodio) y un 10 % ambos tipos de sales. El abrasivo de todas era sílice. El 98% de las pastas dentales analizadas mostraban contenidos de flúor total similares a los descritos por el fabricante, solamente 3 pastas presentaban concentraciones de flúor inferiores a las descritas por el fabricante. El rango obtenido de FT oscilaba entre 398-1.474,6 ppm F, y el 100% de las pastas dentales no mostraron diferencias entre valores de flúor total y flúor soluble.La mayoría de las pastas dentales analizadas contienen una concentración de flúor soluble entre 1.000-1.500 ppm F, correspondiéndose con los valores descritos por los fabricantes. Sin embargo, todavía existen pastas dentales con valores inferiores a los recomendados de mínimo de 1.000 ppm F que no permiten tener la actividad anticaries efectiva desde el punto de vista de salud pública.

This study evaluated the effect of the topical application of melatonin in accelerating bone formation associated with implants 2 months after their application to the tibiae of rabbits. Twenty New Zealand rabbits were used. Twenty implants treated with melatonin and 20 control implants without melatonin were placed in the proximal metaphyseal area of each tibia. Studies of new bone formation were subsequently made at 15, 30, 45 and 60 days. Cortical width and cortical length of new bone formation were measured. Following implantation, an anteroposterior and lateral radiologic study was carried out. Collected samples were sectioned at 5 μm and stained using hematoxylin-eosin, Masson's trichromic and Gordon-Switt reticulin stains. After a 60 day treatment period, melatonin increased the length of cortical bone (95.13±0.42%) versus that around control implants (62.91±1.45%). Related to the perimeter of cortical bone of the tibiae, melatonin induced new bone 88.35±1.56% versus 60.20±1.67% in the control implants. Melatonin regenerated the width and length of cortical bone around implants in tibiae of rabbits more quickly than around control implants without the addition of melatonin.
