Characteristics and distribution of dental anomalies in a Brazilian cleft population

Abstract

Purpose: To determine the prevalence of dental anomalies in 200 cleft patients undergoing orthodontic treatment at the Cleft Rehabilitation Center (CERLAP) of the Pontifical Catholic University of Rio Grande do Sul.Methods: Data regarding patient age, race, gender, cleft type (lip and alveolus, complete lip and palate, or cleft palate), affected side (unilateral or bilateral), agenesis and supernumerary teeth in both arches were assessed from orthodontic records comprised by panoramic, cephalometric, occlusal, and periapical radiographs, study models, intra-and extraoral photographs, obtained at the beginning of the treatment, providing needed information to make an accurate diagnosis of dental anomalies. The collected data were registered in spreadsheets.Results: The mean patient age was 13.5 years old; 86% were white; and 57% male. Complete cleft lip and palate was found at a higher frequency (83%); the left side was most affected (48.5%). Agenesis were found in 66.5% of patients. Maxillary lateral incisors were the most absent teeth (78.5%). Supernumerary teeth were found in 35.5% of patients.Conclusion: Male individuals demonstrated a greater tendency to present clefts and manifest both agenesis and supernumerary teeth. Complete cleft lip and palate prevailed, and the left maxillary lateral incisor was the most absent tooth. Supernumeraries were located distally to the cleft.Key words: Cleft palate; anodontia; tooth, supernumerary; epidemiology ResumoObjetivos: Determinar a prevalência de anomalias dentárias em 200 pacientes com fissura sob tratamento ortodôntico no Centro de Reabilitação Lábio-Palatal (CERLAP) da Pontifícia Universidade Católica do Rio Grande do Sul (PUCRS).Metodologia: Os dados referentes à idade, raça, gênero, tipo de fissura (pré, trans ou pós-forame incisivo), lado afetado (uni ou bilateral), agenesias e supranumerários em ambas arcadas foram avaliados a partir da documentação ortodôntica constituída por radiografias panorâmicas, cefalométricas, oclusais e periapicais, modelos de estudo e fotografias intra e extrabucais obtidas no início do tratamento, fornecendo informações necessárias para diagnóstico de anomalias dentárias. Os dados coletados foram registrados em planilhas.Resultados: A média de idade dos pacientes foi de 13.5 anos; 86% eram brancos; e 57% eram meninos. Fissuras transforame incisivo demonstraram-se mais frequentes (83%); o lado esquerdo foi mais afetado (48.5%). Agenesias foram encontradas em 66.5% dos pacientes. Incisivos laterais superiores foram os dentes mais ausentes (78.5%). Supranumerários foram encontrados em 35.5 % dos pacientes.Conclusão: Meninos demonstraram maior tendência a apresentar fissuras e a manifestar agenesias dentárias e supranumerários. As fissuras completas de lábio e palato prevaleceram e os incisivos laterais superiores foram os dentes mais ausentes. Os supranumerários localizaram-se distalmente à fissura na maioria dos casos.Palavras-chave: Fissura palatina; agenesia dentária; dente supranumerário; epidemiologia

Epidemiological Profile of Cleft Lip and Palate Patients Attending Tertiary Care Hospital and Medical Research Centre, Belgaum, Karnataka–A Hospital Based Study

“…The significant association was observed between consanguineous marriage and cleft deformities which was similar to the study conducted in Andhra Pradesh [4]. Frequency of CLP>CL>CP were found in our study which was similar with the study conducted in Brazil, Iran, Jordan [9,13,19]. The study conducted in Japan revealed that frequency of CLP>CP>CL, in Scotland CP>CLP>CL, in Republic CP>CL>CLP and in Andhra Pradesh CL>CLP>CP [15,17,20,21].…”

“…This study revealed that clefts were more frequent among male population. Our results were similar to the study done in Dehradun, Brazil, Kenya, Iran, Saudi Arabia, Japan and Gujarat [3,9,10,[12][13][14][15][16]. Study conducted in BPKIHS Dhahran, Nepal presented that clefts were common among females (i.e.…”

“…The age of patients ranged from 0.5 to 30 years with an average of 11.1 in a study of Saudi Arabia [7]. In a study conducted in Brazil, age ranged from 2 days to 87 years and mean age was 12.9 years; 13.5±5.6 years and median age was 9.9 years [8,9]. A study in Kenya, age ranged between 1 week and 45 years with average age of 10 months.75% of the cleft cases were in between 0-5 years which was higher than our study [10].…”

Evaluation of the Efficiency of Dental Implants Used in the Oral Rehabilitation in Cleft Patients

“…The osseointegration rate of 94.2% of the total dental implants installed in areas of fissures corroborates with the literature findings that have similar rates in implants installed in non-cracked areas (94%, 95%, 98%) [18][19][20] and in fissured areas (82%, 90% and 98%) [13,21,22]. This percentage was also significantly close to the rates of osseointegration of implants in non-cracked patients who were previously grafted to increase local bone volume, 96% [23] and 97% [24].…”

Ensino, pesquisa e contribuições científicas em odontologia

“…A maioria dos estudos evidencia maior prevalência para o sexo masculino (BEKELE;EKANEM;MEBERATE, 2019;COUTINHO et al, 2009;ESHETE et al, 2017; aaaaaaaaaaaa IMPELLIZZERI et al, 2019;MENEZES et al, 2010;NEVES et al, 2016;PONS-BONALS et al, 2017;PRABAKARAN;THILAGAM;REDDY, 2019;ROLLEMBERG et al, 2019). Tolarova e Cervenka (1998) estimaram que 60% a 80% dos pacientes com FL/P eram homens na amostra por eles avaliada na Califórnia, Estados Unidos.…”
