Association between bariatric surgery and oral health: a literature review

Objective: to review the literature on the relationship between oral health and bariatric surgery in obese individuals. Methods: articles published until March 2021 were searched in the Medline/PubMed, LILACS, BBO, and Web of Science databases. The search used a combination of descriptors related to the words: obesity, bariatric surgery, and oral health. Results: one hundred thirty-five studies were identified in the database search. Of these, 47 were included in this review. The oral changes investigated in the literature for individuals who underwent bariatric surgery were dental caries, tooth wear/erosion, hypersensitivity, periodontal disease, hyposalivation, halitosis, and changes in mastication and oral soft tissue. The evaluated articles showed methodological controversy regarding the study design, follow-up period, sample size, and assessed clinical parameters, which complicated the comparison of studies. Final considerations: there is no consensus in the literature regarding the relationship between oral health and bariatric surgery in obese individuals. Further prospective cohort studies should be conducted to investigate this association better.(AU)

Comparative Effect of Calcium Mesoporous Silica Versus Calcium and/or Fluoride Products on the Reduction of Erosive Tooth Wear and Abrasive Enamel Lesion

Abstract Objective: To evaluate the effect of a calcium nanocompound on the reduction of erosive tooth wear and abrasion. Material and Methods: Bovine enamel specimens (BE), were randomly assigned to the following groups (n = 10): G1 = Calcium mesoporous silica nanoparticles (Ca2+MSNs); G2 = casein phosphopeptide-amorphous calcium phosphate (CPP-ACP, 2% CPP-ACP, GC®); G3 = casein phosphopeptide-amorphous calcium fluoride phosphate (CPP-ACFP, 2% CPP-ACP + 900 ppm F-, GC®); G4 = sodium fluoride NaF (900 ppm F-, positive control); and G5 = distilled and deionized water (negative control). Each product was applied to the exposed area for one minute, three times per day for three consecutive days, and followed by the immersion of the specimens in Sprite Zero™ - a low-pH solution (2.58) for five minutes (Coca-Cola™). After the first and last erosive challenges of the day, the specimens were submitted to abrasion in a toothbrush machine for 15 seconds (200 g/BE). The specimens were analysed using 3D non-contact optical profilometry, with tooth structure loss (TSL) measurements and scanning electron microscopy (SEM). TSL values were analysed by Kruskal-Wallis and Mann-Whitney tests (p<0.05). Results: There were no significant differences between G1 (10.95 µm) and G3 (10.80 µm) treatments for TSL values; however both resulted in significantly reduced TSL values compared with the G5 (16.00 µm) (p<0.05). The G4 (12.26 µm) showed no statistically significant difference when compared to the G5 (16.00 µm). The groups G1 and G3 presented higher surface preservation than the G5. Conclusion: Ca2+MSNs was effective for reducing tooth surface loss caused by erosive tooth wear and abrasion.

Analysis of enamel and material wear by digital microscope: an in-vitro study

Abstract: The objective of the study was to analyze the surface area (SA) of the wear caused by simulated chewing on human enamel and opposing restorative material, namely: composite resin (CR), porcelain fused to metal (PFM), lithium disilicate (LD), or monolithic zirconia (MZr). Forty-eight premolars were selected as enamel specimens and divided randomly into 4 groups (n = 48; n =12) used as antagonists in chewing simulation (250,000 loading cycles) against one of the four selected test materials. Enamel and material specimens were scanned and evaluated under digital microscope, and wear SA (mm2) were recorded. Descriptive statistics, paired t-test, one-way ANOVA, and post-hoc Tukey-HSD tests were used for statistics (p < 0.05). The smallest and largest SA were exhibited by enamel against LD (0.80 mm2) and PFM (1.74 mm2), respectively. PFM (3.48 mm2) showed the largest SA and CR (2.28 mm2) showed the smallest SA. Paired t-test for SA values showed significant difference (p < 0.05) in all wear comparisons between materials and enamel antagonists. The wear of materials were greater than that of their respective enamel antagonists (p < 0.05). One-way ANOVA of the logarithmic means of wear SA revealed significant differences (P<0.05). Post-hoc Tukey test revealed significance for PFM (p < 0.05) with other materials. Wear of all test materials was greater compared to the wear of enamel antagonists. PFM and LD caused the largest and the smallest enamel wear, respectively. CR, LD, and MZr are more resistant than PFM to wear after simulated chewing against enamel.

Bariatric surgery impact on gastroesophageal reflux and dental wear: a systematic review / Impacto da cirurgia bariátrica no refluxo gastroesofágico e no desgaste dental: uma revisão sistemática

ABSTRACT Introduction: Several oral problems may be perceived in individuals who were submitted to bariatric surgery, due to metabolic and behavioral changes relative to diet and oral hygiene. Tooth wear appears to suffer impact after bariatric surgery, because there may be an increase in gastroesophageal reflux. Objective: To systematically review the literature regarding the impact of bariatric surgery on gastroesophageal reflux and tooth wear. Method: The following databases were accessed by two independent, calibrated examiners: PubMed, Medline, Lilacs, Scielo and Cochrane using the following descriptors: "bariatric surgery" AND "dental erosion" OR "bariatric surgery" AND "dental erosion" AND "gastroesophageal reflux disease". After excluding duplicate studies, 12 studies were initially evaluated by the title and abstract. The excluded studies were those without relevance to the present research, literature review studies and case reports. Thus, four articles were included in this study. All the articles evaluated indicated high association between gastroesophageal reflux and tooth wear in patients submitted to bariatric surgery. Association of these outcomes was more evident six months after the surgical procedure. Conclusion: Patients submitted to bariatric surgery showed higher prevalence of gastroesophageal reflux and tooth wear.

RESUMO Introdução: Diversos problemas bucais podem ser percebidos nos indivíduos que foram submetidos à cirurgia bariátrica, frente às mudanças metabólicas e comportamentais referentes à alimentação e higienização. O desgaste dentário parece sofrer impacto após a cirurgia bariátrica, uma vez que pode ocorrer o aumento do refluxo gastresofágico após a operação. Objetivo: Analisar o impacto da cirurgia bariátrica no refluxo gastresofágico e no desgaste dentário por meio de uma revisão sistemática da literatura. Método: As seguintes bases de dados foram acessadas por dois examinadores independentes e calibrados: PubMed, Medline, Lilacs, Scielo e Cochrane usando os descritores: "bariatric surgery" AND "dental erosion" OR "bariatric surgery" AND "dental erosion" AND "gastroesophageal reflux disease". Após a exclusão dos estudos duplicados, 12 estudos foram avaliados inicialmente pelo título e resumo. Foram excluídos os sem relevância para a presente pesquisa, os de revisão da literatura e os relatos de caso. Sendo assim, foram incluídos neste estudo quatro artigos. Todos os artigos avaliados indicaram uma alta associação entre refluxo gastresofágico e desgaste dentário em pacientes submetidos à cirurgia bariátrica. A associação destes desfechos foi mais evidente após seis meses do procedimento cirúrgico. Conclusão: Pacientes submetidos à cirurgia bariátrica mostram maior prevalência de refluxo gastresofágico e desgaste dentário.

Erosive tooth wear-why clinicians should be aware of this condition

Introduction: Erosive tooth wear (ETW) is defined as a chemical-mechanical process leading to the cumulative loss of hard dental tissue without the involvement of bacteria. Objective: to give to clinicians an overview about most important ETW topics. Data source: main scientific data base (PubMed, Lilacs) in the last 10 years, with the keywords: dental erosion, diagnosis and prevention. Classical articles were selected for the realization of an integrative literature review. Data synthesis : the prevalence of ETW has been reported to range from 10% to 80% in children and 4% to 82% in adults. The management of ETW should include early diagnosis, the evaluation of different etiological factors, risk identification and the proposal of preventive measures to avoid the progression of the condition. These measures include fluoride exposure, use of low abrasive toothpastes, clinical monitoring, and in more severe cases sealant application and restorations. Patients suffering from eating disorders with purging behaviour and gastroesophageal reflux disease are considered the most important risk groups. Conclusion : Clinicians should be aware of this condition with growing prevalence, once substance loss is an irreversible condition, providing prompt preventive measures during the early stages that are essential to reduce ETW.

Bruxismo de sueño en niños y adolescentes / Sleep bruxism in children and adolescents

El bruxismo es una actividad muscular mandibular repetitiva, caracterizada por apriete y rechinamiento dentario. Se considera un fenómeno regulado por el sistema nervioso central, principalmente, e influido por factores periféricos. Tiene 2 manifestaciones circadianas distintas: puede ocurrir durante el sueño -indicado como bruxismo de sueño- o durante la vigilia -indicado como bruxismo despierto-. El bruxismo es mucho más que solo el desgaste que podemos observar en los dientes: de hecho, se asocia con dolor orofacial, cefaleas, trastornos del sueño, trastornos respiratorios durante el sueño como el síndrome de apnea e hipoapnea del sueño, trastornos del comportamiento o asociados al uso de fármacos. Además, se ve influido por factores psicosociales y posturales, lo que indica que parafunciones oromandibulares, los trastornos temporomandibulares, la maloclusión, los altos niveles de ansiedad y de estrés, entre otros, podrían influir en la ocurrencia de bruxismo. Su etiología es considerada hoy como multifactorial. Su detección temprana, diagnóstico, tratamiento y la prevención de sus posibles consecuencias en los pacientes es responsabilidad del pediatra y del odontólogo. El objetivo de esta revisión es actualizar los conceptos sobre esta patología y alertar a los profesionales de la salud sobre su detección precoz y su manejo oportuno.

Bruxism is a rhythmic masticatory muscle activity, characterized by teeth grinding and clenching. This is a phenomenon mainly regulated by the central nervous system and peripherally influenced. It has two circadian manifestations, during sleep (sleep bruxism) and awake states (awake bruxism). Bruxism is much more than just tooth wearing. It is currently linked to orofacial pain; headaches; sleep disorders; sleep breathing disorders, such as apnea and hypopnea sleep syndrome; behavior disorders, or those associated with the use of medications. It is also influenced by psycho-social and behavior factors, which means that oromandibular parafunctional activities, temporomandibular disorders, malocclusion, high levels of anxiety and stress, among others, may precipitate the occurrence of bruxism. Nowadays, its etiology is multifactorial. The dentist and the pediatrician are responsible for its early detection, diagnosis, management, and prevention of its possible consequences on the patients. The aim of this review is to update the concepts of this disease and to make health professionals aware of its early detection and its timely management.

[Global Beauty and functional rehabilitation by scheduled hearing in a Bruxism case]

Bruxism is an unconscious behavior characterized by contractions of the masticatory muscles outside the physiological functions. The dentist is required to manage the oral consequences of bruxism; the most remarkable one is dental wear. When the dental degree of damage becomes important, a total fixed prosthetic treatment must be conceived. The prosthetic rehabilitation aims at restoring all the occlusal functions [centering, guidance], to allow the entire masticatory system to operate with minimal constraints. It must redefine esthetic criteria, reestablish a good functional occlusal stability and optimize the functions of the masticatory system. These basic concepts are illustrated by the presentation of a clinical case of a patient suffering from bruxism

Prevalence and severity of tooth wear in 12 to 15 year old school children in the Gurgaon district, Haryana, India: a cross-sectional study / Prevalência e severidade de desgaste dentário em escolares de 12 a 15 anos de idade no Distrito Gurgaon, Haryana, India: um estudo transversal

Tooth wear is an ever increasing problem. However, literature on tooth wear prevalence is scarce. Therefore, the aim of the present study was to assess the prevalence and severity of tooth wear among 12 to 15 year old children of private schools of Farukhnagar block (Gurgaon) Haryana. Material and Methods: 973 school children in the age group of 12 to 15 year from the Gurgaon district were included in the study. All permanent teeth were examined by two trained calibrated examiners using CPITN probes in four surfaces, namely cervical (C), buccal (B), occlusal (O) or incisal (I) and palatal (P) or lingual (L) surface using Tooth Wear Index (TWI) . SPSS 19 was used for descriptive statistics and chi-square test. Results: A total of 26,230 teeth were examined. Overall prevalence of tooth wear was 29.7%. Most frequently affected teeth were the Incisors (15.4%), followed by the Molars (7.4%). Incisal/occlusal surface was the most commonly affected surface. All the tooth wear lesions observed were mostly confined to the enamel (76.4%). Boys had statistically significant higher tooth wear prevalence (16.2%) compared to girls (13.5%). Dental fluorosis determined higher tooth wear prevalence (61.5%). Conclusion: There is high prevalence of tooth wear among school children, and boys have more tooth wear compared to girls. Dental fluorosis is associated with high risk for tooth wear. Thus tooth wear poses a significant public health problem, and steps should be taken for early diagnosis, prevention and management...

O desgaste dos dentes é um problema crescente. No entanto, a literatura sobre a prevalência de desgaste dentário é escassa. Portanto, o objetivo do presente estudo foi avaliar a prevalência e a severidade do desgaste dentário entre as crianças de 12 a 15 anos de idade de escolas particulares de Farukhnagar (Gurgaon) Haryana. Material e métodos: 973 crianças em idade escolar na faixa etária de 12 a 15 anos do bairro de Gurgaon foram incluídas no estudo. Todos os dentes permanentes foram examinados por dois avaliadores treinados calibrados utilizando sondas CPITN em quatro superfícies [cervical (C), vestibular (B), oclusal (O) ou incisal (I), e palatina (P) ou lingual (L)] da superfície do dente por meio do Índice de Desgaste Dental (IDD). O SPSS 19 foi utilizado para a estatística descritiva e teste do qui-quadrado. Resultados: Um total de 26.230 dentes foi examinado. A prevalência de desgaste dentário foi de 29,7%. Os dentes mais afetados foram os incisivos (15,4%), seguidos pelo molares (7,4%). A superfície incisal/oclusal foi a mais comumente afetada.

Conclusão: Há uma alta prevalência de desgaste dentário em escolares, e os meninos apresentam mais desgaste em comparação com as meninas. A fluorose dental é associada ao alto risco de desgaste dentário. Assim, o desgaste do dente representa um importante problema de saúde pública, devendo ser tomadas medidas para o diagnóstico precoce, a prevenção e o tratamento...

Impact of filler size and distribution on roughness and wear of composite resin after simulated toothbrushing

OBJECTIVES: Nanofilled composite resins are claimed to provide superior mechanical properties compared with microhybrid resins. Thus, the aim of this study was to compare nanofilled with microhybrid composite resins. The null hypothesis was that the size and the distribution of fillers do not influence the mechanical properties of surface roughness and wear after simulated toothbrushing test. MATERIAL AND METHODS: Ten rectangular specimens (15 mm x 5 mm x 4 mm) of Filtek Z250 (FZ2), Admira (A), TPH3 (T),Esthet-X (EX), Estelite Sigma (ES), Concept Advanced (C), Grandio (G) and Filtek Z350 (F) were prepared according to manufacturer's instructions. Half of each top surface was protected with nail polish as control surface (not brushed) while the other half was assessed with five random readings using a roughness tester (Ra). Following, the specimens were abraded by simulated toothbrushing with soft toothbrushes and slurry comprised of 2:1 water and dentifrice (w/w). 100,000 strokes were performed and the brushed surfaces were reanalyzed. Nail polish layers were removed from the specimens so that the roughness (Ra) and the wear could be assessed with three random readings (µm). Data were analyzed by ANOVA and Tukey's multiple-comparison test (α=0.05). RESULTS: Overall outcomes indicated that composite resins showed a significant increase in roughness after simulated toothbrushing, except for Grandio, which presented a smoother surface. Generally, wear ofnanofilled resins was significantly lower compared with microhybrid resins. CONCLUSIONS: As restorative materials suffer alterations under mechanical challenges, such as toothbrushing, the use of nanofilled materials seem to be more resistant than microhybrid composite resins, being less prone to be rougher and worn.

Tooth wear in patients submitted to bariatric surgery

Bariatric surgery may cause frequent vomiting episodes and gastroesophageal reflux, which promote the contact of gastric acids with the teeth leading to irreversible loss of tooth structure. The aim of this study was to assess prevalence of tooth wear in bariatric patients. One hundred and twenty-five patients were examined at a Public Hospital in São Luis, MA, Brazil, between July and October 2010, being patients who had already been submitted to the bariatric surgery at least 6 months previously (Bariatric group), morbidly obese patients who were on the waiting list for this surgery (Obese group) and patients who were waiting for ambulatory medical care in other sectors (Control group). The patients answered an investigative questionnaire and were clinically examined using the Basic Erosive Wear Examination (BEWE) scoring system, which allows the classification of the severity of noncarious dental lesions (NCDL) and evaluation of risk. All patients presented some degree of tooth wear at different levels. However, the presence of NCDL was associated with the group to which the patient belonged. The bariatric patients showed higher prevalence and a statistically significant level of risk with regard to NCDLs when compared with the other patients, followed by the obese and control groups. Reflux and vomiting did not seem to influence NCDL positively.

Cirurgia bariátrica pode provocar freqüentes episódios de vômito e refluxo gastroesofágico o que promove o contato dos ácidos gástricos com os dentes fazendo que haja perda irreversível de estrutura dental. Este estudo teve como objetivo avaliar a prevalência de desgaste dentário em pacientes bariátricos. Foram examinados 125 pacientes em um Hospital Público de São Luís, MA no período de julho a outubro de 2010, distribuídos em pacientes que já tinham sidos submetidos à cirurgia bariátrica há pelo menos 6 meses (Grupo bariátrico), obesos mórbidos que estavam na lista de espera para esta cirurgia (Grupo obeso) e por pacientes que esperavam por consulta médica ambulatorial em outros setores (Grupo controle). Os pacientes responderam a um questionário investigativo e foram examinados clinicamente utilizando o “Basic Erosive Wear Examination” - BEWE (Índice Básico do Desgaste Erosivo) que permite a classificação da severidade das lesões não-cariosas e avaliação de risco. Todos os pacientes apresentaram algum grau de desgaste dentário em diferentes níveis. No entanto, a presença de LDNC (lesão dental não-cariosa) estava associada ao grupo que o paciente pertencia. O grupo bariátrico apresentou maior prevalência e nível de risco em relação às LDNC’s estatisticamente significante quando comparado aos outros grupos, seguido pelo grupo de obeso e controle. Refluxo e vômito parecem não influenciar positivamente nas LDNC.

Interfaces between bariatric surgery and oral health: a longitudinal survey / Interface entre cirurgia bariátrica e saúde bucal: estudo longitudinal

PURPOSE: To evaluate oral changes, such as dental caries, periodontal disease, dental wear and salivary flow in bariatric patients. Fifty four obese patients who underwent bariatric surgery were studied before (n=54), up after 3 months (n=24) and 6 months (n=16). METHODS: Indices for evaluating oral conditions were: DMFT, CPI, DWI and salivary flow. OIDP questionnaire was used to assess the impact of oral health on quality of life. ANOVA and Spearman correlation were used (p<0.05). RESULTS: DMFT was 17.6±5.7, 18.4±4.1 and 18.3±5.5 (P>0.05), presence of periodontal pockets in 50 percent, 58 percent and 50 percent of patients (p>0.05), tooth wear in dentin present in 81.5 percent, 87.5 percent and 87.5 percent before, 3 and 6 months after surgical treatment respectively. There were differences between the three periods for prevalence and severity of dental wear (p = 0.012). Salivary flow was 0.8±0.5 ml/min before surgery, 0.9±0.5 ml/min for 3 months and 1.1±0.5m/min for 6 months (p>0.05). The impact of oral health on quality of life decreased with time after bariatric surgery (p= 0.029). CONCLUSION: The lifestyle changes after bariatric surgery and these changes may increase the severity of pre-existing dental problems. However, these alterations in oral health did not influence the quality of life.

OBJETIVO: Avaliar alterações bucais, como cárie dentária, doença periodontal, desgaste dentário e fluxo salivar, em pacientes bariátricos. MÉTODOS: Cinquenta e quatro pacientes obesos, submetidos à cirurgia bariátrica, tiveram suas condições bucais avaliadas antes (n=54), aos 3 meses (n=24) e aos 6 meses (n=16) após a cirurgia bariátrica. Os índices para avaliação das condições bucais foram: CPOD, IPC, IDD e o volume de fluxo salivar. O questionário OIDP foi utilizado para verificar o impacto da saúde bucal na qualidade de vida. ANOVA e correlação de Spearman foram utilizados para análise estatística (p<0,05). RESULTADOS: CPOD foi 17,6±5,7, 18,4±4,1 e 18,3±5,5 (p>0,05), bolsa periodontal foi encontrada em 50 por cento, 58 por cento e 50 por cento dos pacientes (p>0,05) e o desgaste dentário em dentina em 81,5 por cento, 87,5 por cento e 87,5 por cento dos pacientes, respectivamente antes, 3 meses e 6 meses após a cirurgia bariátrica. Houve diferença significativa entre os três períodos estudados, quanto à prevalência e à severidade do desgaste dentário (p=0,012). O fluxo salivar foi 0,8±0,5 ml/min antes, 0,9±0,5 ml/min aos 3 e 1,1±0,5 ml/min aos 6 meses após cirurgia (p>0,05). O impacto da saúde bucal na qualidade de vida diminuiu com o tempo decorrido após cirurgia bariátrica (p=0,029). CONCLUSÕES: As mudanças no estilo de vida após a cirurgia bariátrica podem aumentar a gravidade de problemas bucais pré-existentes. Entretanto, esta alteração na condição bucal pode não influenciar a qualidade de vida.

Tomada de decisão para as lesões cervicais não-cariosas por cirurgiões-dentistas da cidade de São Miguel do Oeste-SC / Decision making for non-carious cervical lesions by dentists in the city of São Miguel do Oeste-SC

O presente estudo avaliou a tomada de decisão dos cirurgiões-dentistas da cidade de São Miguel do Oeste, Santa Catarina, em relação à classificação, etiologia e o tratamento das lesões cervicais não-cariosas. A pesquisa foi descritiva e utilizou como instrumento de pesquisa questionários com perguntas a respeito de duas imagens clínicas de lesões cervicais não-cariosas. A amostra contou com 31 cirurgiões-dentistas sócios da Associação Brasileira de Odontologia de Santa Catarina. Os resultados mostraram que a maioria dos cirurgiões-dentistas classificou a lesão da primeira figura como abrasão (54,8%), sendo a sua principal etiologia a escovação dentária (87,1%) e o tratamento escolhido foi a proservação com aplicações tópicas de flúor e desensibilizantes (90,3%). A segunda figura foi classificada como abfração (67,7%), sendo as forças oclusais a sua principal etiologia (41,9%), seguida pela escovação dentária (38,7%) e o tratamento de escolha foi restaurador (87,1%). Verificou-se que apesar da dificuldade na determinação do diagnóstico, das causas e do tratamento desse tipo de lesão, a maioria dos profissionais tomou decisões semelhantes frente às lesões cervicais não-cariosas.

The present study has evaluated the decision making of the dentists acting in São Miguel do Oeste, Santa Catarina, related to the classification, etiology and treatment of non-carious cervical lesions. The study was descriptive and used as research instrument, questionnaires with questions about two clinical images of non-carious cervical lesions. The sample was composed of 31 dentists, all belonging to the Association of Brazilian Dentists of the state of Santa Catarina. The results show that most dentists classified the first picture lesion as abrasion (54.8%). The toothbrushing of the teeth was the preferred etiology (87.1%) and the chosen treatment was follow up with topical fluoride and desensibilizing agents (90.3%). The second picture was classified as abfraction (67.7%) and the occlusal forces were the main etiology (41.9%), followed by toothbrushing (38.7%) and the treatment of choice was the restoration (87.1%). It was concluded that in spite of the difficulty in determining the diagnosis, the etiology and treatment of this type of injury, most professionals decision maked cervical lesions similar.

Morfologia dentofacial e características oclusais dos índios Arara: revisitando o papel da hereditariedade e da dieta na etiologia da má oclusão / Dentofacial morphology and occlusal characteristics of Arara indigenous: revisiting the role of heredity and diet in the etiology of malocclusion

A influência da dieta e da hereditariedade nas características dentofaciais foi avaliada através do exame de duas populações indígenas amazônicas divididas por um processo de fissão linear. Os indígenas que constituem a aldeia Arara-Iriri são descendentes de um único casal expulso da aldeia Arara-Laranjal. O crescimento da aldeia Iriri ocorreu pelo acasalamento de parentes próximos, ratificado por um alto coeficiente de consanguinidade (F=0,25, p<0,001). A epidemiologia da má oclusão e das características da face foi analisada nos indivíduos entre dois e 22 anos, das aldeias Iriri (n=46) e Laranjal (n=130). A biometria da dentição e da face foi obtida em 55 indígenas em dentição permanente sem perdas dentárias, através da fotogrametria facial e dos modelos de gesso. O desgaste dentário foi examinado em 126 indivíduos através da análise de regressão múltipla. Os resultados revelaram uma determinação significativa da idade no desgaste dos dentes (R2=87,6, p<0,0001), que se mostrou semelhante entre as aldeias (R2=0,027, p=0,0935). Por outro lado, diferenças marcantes foram observadas nas características dentofaciais. Revelou-se uma face mais vertical (dolicofacial) entre os índios Iriri e o predomínio do tipo braquifacial nos indígenas da aldeia original, corroborado pela fotogrametria. Uma face sagitalmente normal foi observada em 97,7% da aldeia Laranjal, enquanto faces convexas (26,1%, RR-16,96) e côncavas (15,2%, RR=19,78) eram mais prevalentes na aldeia Iriri (p<0,001). A biprotrusão, com consequente redução do ângulo nasolabial, era uma característica comum entre os Arara, porém com maior prevalência no grupo Iriri (RP=1,52, p=0,0002). A prevalência da má oclusão foi significativamente mais alta na aldeia Iriri (RP= 1,75, p=0,0007). A maioria da população da aldeia original (83,8%) apresentou uma relação normal entre os arcos dentários, contudo, na aldeia resultante (Iriri), 34,6% dos indivíduos era Classe III (RP=6,01, p<0,001) e 21,7% era Classe...

The influence of diet and genetics on dentofacial features was examined through the analysis of two split indigenous Amazon populations originated by a process of a linear fission. The Arara-Iriri indigenous are descendants of a single couple who were expelled from a larger village (Arara-Laranjal). In the resultant new village, the initial expansion occurred through the mating of closely related people, causing a high coefficient of inbreeding (F=0.25, p<0.001). The epidemiology of malocclusion and facial characteristics were analyzed in individuals aged from 2 to 22 years, from the Arara-Iriri (n=46) and Arara-Laranjal (n=130) villages. The biometric study of the dentition and face was performed in the permanent dentition of the indigenous without tooth loss (n=55) by facial photogrammetry and dental casts analysis. Tooth wear was examined in 126 individuals in the permanent dentition through multiple regression analysis. Findings pointed out a significant determination of age on tooth wear (R2=87.6, p<0.0001), which was similar between the villages (R2=0.027, p=0.0935). However, we found marked differences in the dentofacial morphology. The indigenous of the Iriri village presented a more vertical face (dolichofacial) compared to the people of the original village, predominantly braquifacial. This clinical data was corroborated by facial photogrammetry. A sagitally normal face was observed in 97.7% of the Laranjal village, while convex (26.1%, RR=16.96) and concave faces (15.2%, RR=19.78) were significantly more prevalent in the Iriri village (p<0.001). Biprotrusion, with consequent reduction of nasolabial angle, was a common feature among the Arara indigenous, but its occurrence in the Iriri village was higher (RP=1.52, p=0.0002). The prevalence of malocclusion was significantly higher in the Iriri population (RP=1.75, p=0.0007). While the majority of the population (83.8%) in the Laranjal village presented a normal ...(AU)
