Patients' perception of orthodontic retainers: a systematic review.

BACKGROUND: Orthodontic retainers are widely used to prevent relapses after orthodontic treatment; however, evidence about patients' perceptions of retainers is lacking. OBJECTIVE: To assess patients' perception of orthodontic retainers. SEARCH METHODS: PubMed, Web of Science, Scopus, LILACS, LIVIVO, Cochrane Library, and gray literature (Google Scholar) were searched without date or language restrictions. A manual search of the reference lists of the included articles was also performed. SELECTION CRITERIA: Studies comparing patients' perceptions of wearing orthodontic retainers were included. DATA COLLECTION AND ANALYSIS: According to the study design, the risk of bias (RoB) assessment was performed using RoB 2.0 or ROBINS-I. The level of evidence was assessed through the GRADE (Grading of Recommendations, Assessment, Development and Evaluation) tool. RESULTS: Seventeen studies met the eligibility criteria. After the RoB assessment, 12 randomized controlled trials presented a high RoB, and 4 non-randomized controlled trials presented a moderate RoB. The certainty of evidence was classified as very low for the four assessed outcomes. The studies generally reported an initial temporary negative impact of orthodontic retainers. Different esthetic, functional, and ease-of-use advantages are reported using removable and fixed retainers. A quantitative analysis was not performed due to the considerable clinical and methodological heterogeneity among the studies. CONCLUSION: The current evidence, although very limited, suggests that orthodontic retainers have an initial negative impact related to discomfort and functional limitations, but they seem to regress over time. There is a preference for thermoplastic over Hawley-type retainers. However, thermoplastic retainers cause different functional difficulties, and bonded retainers present the advantage of affecting speech function less than orthodontic removable retainers, although they can facilitate oral hygiene problems. REGISTRATION: PROSPERO (CRD42022306665).

Can lingual spurs alter the oral health-related quality of life during anterior open bite interceptive treatment? A systematic review.

INTRODUCTION: The use of lingual spurs has been described as one efficient option, with great stability of results, but with scarce information of toleration for use in the mixed and permanent dentition phases. OBJECTIVE: The purpose of this study was to assess the impact of lingual spurs on the oral health-related quality of life of children and/or adolescents during anterior open bite treatment. METHODS: The review was recorded in the PROSPERO database. Eight electronic databases and partial gray literature were searched, without restrictions until march 2022. A manual search was also performed in the references of the included articles. Studies assessing the impact of lingual spurs on the oral health-related quality of life were included. Risk of bias was assessed using JBI or ROBINS-I tool, according to the study design. The level of evidence was assessed through GRADE. RESULTS: Five studies met the eligibility criteria. Two non-randomized clinical trials had a serious risk of bias. Of the case-series studies, two had a low risk of bias and the other, a moderate risk of bias. The certainty of the evidence was classified as very low for all the evaluated results. In general, the studies reported an initial negative impact with the use of lingual spurs, however this was transitory in nature. A quantitative analysis was not performed due to the great heterogeneity between the studies. CONCLUSION: Current evidence, although limited, suggests that lingual spurs have an initial transient negative impact during interceptive treatment. Additional well-conducted randomized clinical trials are needed.

RESUMO Introdução: O uso de esporões linguais tem sido descrito como uma opção eficiente, com grande estabilidade de resultados, mas com poucas informações quanto à tolerância de seu uso nas fases de dentição mista e permanente. Objetivo: O objetivo deste estudo foi avaliar o impacto dos esporões linguais na qualidade de vida relacionada à saúde bucal de crianças e/ou adolescentes durante o tratamento da mordida aberta anterior. Métodos: Essa revisão foi registrada no banco de dados PROSPERO. Oito bases de dados eletrônicas e parte da literatura cinzenta foram pesquisadas, sem restrições, até março de 2022. Uma busca manual também foi realizada nas referências dos artigos incluídos. Estudos avaliando o impacto dos esporões linguais na qualidade de vida relacionada à saúde bucal foram incluídos. O risco de viés foi avaliado usando a ferramenta JBI ou ROBINS-I, de acordo com o desenho do estudo. O nível de evidência foi avaliado por meio do GRADE. Resultados: Cinco estudos preencheram os critérios de elegibilidade. Dois ensaios clínicos não randomizados apresentaram sério risco de viés. Dos estudos de série de casos, dois tiveram baixo risco de viés e o outro, risco moderado de viés. A certeza da evidência foi classificada como muito baixa para todos os resultados avaliados. Em geral, os estudos relataram um impacto negativo inicial com o uso dos esporões linguais; porém, de caráter transitório. Não foi realizada análise quantitativa, devido à grande heterogeneidade entre os estudos. Conclusão: As evidências atuais, embora limitadas, sugerem que os esporões linguais têm um impacto negativo transitório inicial durante o tratamento interceptativo. São necessários mais ensaios clínicos randomizados bem conduzidos.

Lower fixed retainers: bonded on all teeth or only on canines? A systematic review.

OBJECTIVE: To evaluate the stability after orthodontic treatment between two types of lower fixed retainers: those bonded onto all anterior teeth or those bonded only onto the canines. MATERIALS AND METHODS: The following electronic databases were consulted: PubMed, Scopus, Web of Science, Cochrane Library, Lilacs, OpenGrey, ClinicalTrials, and Google Scholar. No restriction of language or year were applied. After selection of studies, risk-of-bias evaluation and qualitative synthesis of the included studies were performed using The Cochrane Collaboration's tool for randomized studies and the "Risk of Bias in Non-randomized Studies of Interventions" (ROBINS-I) tool for nonrandomized studies, and a summary of the overall strength of evidence was presented using the "Grading of recommendations, assessment, development and evaluation" tool. RESULTS: Among the 180 studies retrieved from the searches, five were included in this review. Three of them showed a low risk of bias, while two presented a high risk of bias. With regard to stability, two studies reported better stability for retainers bonded to all six teeth, while the other three showed no difference. The retainer bonded to all teeth presented a higher breakage rate in one study. CONCLUSIONS: Stability seems better with lower fixed retainers bonded on all anterior teeth. The breakage rate may not change according to the bonding. However, studies with greater methodological soundness are necessary to reach a more reliable conclusion.

Doença de Riga-Fede: relato de dois casos - um conservador e outro radical / Riga-Fede disease: double case report - a conservative and other radical

A lesão de Riga-Fede é uma ulceração traumática na superfície ventral da língua comumente associada a dentes natais ou neonatais. Esta lesão pode resultar em uma inadequada sucção do leite e alimentação, colocando o recém-nascido em risco de deficiências nutricionais. Nestas circunstâncias, intervenções dentais devem ser feitas com tratamento conservador (suavização da borda incisal) ou radical (exodontia). A decisão pelo tratamento radical é feita na presença de debilidade nutricional causada pela dificuldade de amamentação, em casos de mobilidade dentária avançada, rizogênese em estado inicial e diante de lesões com maiores extensões. O atual trabalho visa discutir dois casos com diferentes tratamentos, um conservador em que o paciente apresentava 28 dias de vida, discreto comprometimento na alimentação e não estava perdendo peso; e outro radical, em que o paciente apresentava 6 dias de vida dificuldade na alimentação e perda de peso

Riga-Fede disease is a traumatic ulceration on the ventral region of the tongue, usually associated with natal or neonatal teeth. This lesion can result in an inappropriate milk suction and feeding, leading the newborn in risk of inadequate nutrients intake. Under this circurnstances, dental intervention must be done as a conservative treatment (smoothening off the incisors edges) or radical (extraction). Oecision for the radical treatment is taken due the pre sence of nutritional deficiency by breastfeeding difficulty, in cases of advanced dental mobility teeth with initial rhizogenesis and larger lesions. The main objective of the present study is discuss two cases with different treatments, a conservative over a patient with 28 days of life quiet deficiency feeding and no weight 1055. And other radical, on a 6 days life patient with inappropriate feeding and and weight loss
