OBJETIVOS: Avaliar a prevalência e distribuição de três anomalias dentárias: agenésias, dentes supranumerários e impactações (excluindo o terceiro molar). Como objetivo secundário, avaliar a prevalência e distribuição de terceiros molares impactados.
MATERIAIS E MÉTODOS: Foram analisadas ortopantomografias de pacientes que frequentaram as consultas de Medicina Dentária da FMDUL entre abril de 2019 e abril de 2022. Para cada anomalia, estabeleceram-se critérios de inclusão e exclusão, avaliando-se os seguintes parâmetros: sexo, idade, localização e dente, bem como, para a impactação de terceiros molares, a angulação e a patologia associada. Na análise estatística, utilizou-se o teste Qui-Quadrado (χ2) e uma significância de 95% (p=0,05).
RESULTADOS: Foram analisadas 1145 ortopantomografias. Nas agenésias, a prevalência foi de 7,32%. O sexo feminino (60,87%), a faixa etária dos 12-19 anos (39,13%), a maxila (75%) e o dente 12 (22,92%) foram os mais afetados. Nos dentes supranumerários, a prevalência foi de 1,96%. O sexo masculino (85,71%), a faixa etária dos 20-29 anos (85,71%), a maxila (100%) e o dente 29 (55,56%) foram os mais afetados. Nas impactações (excluindo o terceiro molar), a prevalência foi de 2,38%. O sexo feminino (65,22%), a faixa etária dos 50- 59 anos (26,09%), a maxila (70,37%) e os dentes 13 e 23 (33,33%) foram os mais afetados. Na impactação de terceiros molares, a prevalência foi de 16,95%. O sexo masculino (50,81%), a faixa etária dos 20-29 anos (40,54%), a mandíbula (54,71%), o dente 38 (28,27%), a angulação vertical (39,01%) e a radiolucidez distal (41,18%) foram os mais prevalentes.
CONCLUSÃO: As anomalias dentárias estudadas afetam sexos, faixas etárias e dentes diferentes, mas a maxila assume-se, maioritariamente, como localização preferencial. Nas impactações de terceiros molares, a angulação vertical e a radiolucidez distal são as mais prevalentes. Mais estudos com protocolos e amostras padronizados são necessários de forma reduzir o erro e clarificar os resultados.
AIMS: To determine the prevalence and distribution of three dental anomalies: agenesis, supernumerary teeth and impacted teeth (excluding third molar). The secondary aim was to determine the prevalence and distribution of impacted third molars. MATERIALS AND METHODS: Orthopantomography radiographs of patients who attend dental medicine appointments in FMDUL between April 2019 and April 2022 were analyzed. For each anomaly, inclusion and exclusion criteria were established and different parameters were assessed: gender, age, jaw and tooth, as well as, for impacted third molar, teeth angulation and associated pathology. Statistical analysis was made using Chi-Square test (χ2) and a significance of 95% (p=0.05). RESULTS: There were analyzed 1145 orthopantomography radiographs. The prevalence of agenesis was 7.32%. Females (60.87%), 12-19 years (39.13%), maxilla (75%) and tooth 12 (22.92%) were the most frequently found. The prevalence of supernumerary teeth was 1.96%. Males (85.71%), 20-29 years (85.71%), maxilla (100%) and tooth 29 (55.56%) were the most frequently found. The prevalence of impacted teeth (excluding third molar) was 2.38%. Females (65.22%), 50-59 years (26.09%), maxilla (70.37%) and teeth 13 and 23 (33.33%) were the most frequently found. The prevalence of impacted third molar was 16.95%. Males (50.81%), 20-29 years (40.54%), mandible (54.71%), tooth 38 (28.27%), vertical position (39.01%) and distal radiolucency (41.18%) were the most frequently found. CONCLUSION: The studied anomalies affect different genders, ages and teeth, but maxilla is, mostly, the most prevalent location. In impacted third molars, vertical angulation and distal radiolucency were the most frequently found. More studies with standardized protocols and samples are required to reduce the error and to clarify the results.
