Evaluating the Thickness of the Root Canal Dentin Wall in Primary First Molars Using Cone-beam Computed Tomography.

Aim: To evaluate the thickness of the root canal dentin wall in the cervical, middle, and apical third of primary first molars. Materials and methods: Cross-sectional study consisting of 30 cone-beam computed tomography (CBCT) images of primary maxillary and mandibular first molars, with crown, and root integrity. The wall dentin thickness of each canal was measured in three axial views, divided into distal (D), mesial, lingual/palatine, and buccal surfaces. Results: The smallest dentin wall thickness of the maxillary molar was located on the mesial surface of the mesiobuccal (MB) canal apical third (mean 0.55 ± 0.04 mm). The buccal and palatal (P) surfaces of the distobuccal (DB) and P canals showed the smallest dentin thickness on the cervical third (0.62 ± 0.02 mm). On the mandibular molar, we found the smallest dentin thickness on the apical third [lingual surface of the MB canal and buccal surface of the mesiolingual (ML) canal] with a mean of 0.41 ± 0.07 mm. Additionally, the dentin thickness is average of the D canal was about 0.67 ± 0.11 mm. Conclusion: It is essential to understand the primary first molar's anatomy to reduce possible complications in pediatric patients from instrumentation during root canal treatments. Clinical significance: Pulpectomy is among the most challenging procedures in pediatric dentistry and the knowledge of the root anatomy of primary teeth allows the professional to make better clinical decisions and reduce possible risks during root canal treatment.

Association between knowledge and attitudes towards pediatric obstructive sleep apnea and dental specialty.

OBJECTIVE: To associate the knowledge and attitudes about Pediatric Obstructive Sleep Apnea (POSA) with the specialty of dentists in Metropolitan Lima, Peru. METHODS: A cross-sectional, analytical observational study was carried out during 2021-2022. Two hundred and ten orthodontists and pediatric dentists were surveyed using the adapted and validated Spanish translation of the OSAKA-KIDS questionnaire and additional sociodemographic questions. RESULTS: The data indicated an association between dental specialty and the professional's knowledge about POSA. Orthodontists were 59% less likely to have acceptable knowledge, compared to pediatric dentists (p = .013, IC 95% 0.21-0.83). The study revealed an association between the professional's attitudes and three intervening variables: age (p = .025), clinical experience (p = .049) and sector of practice (p = .020). CONCLUSION: Knowledge was associated with the dental specialty of professionals in the sample included, whilst attitudes were not.

Calidad de vida relacionada a la salud oral de preescolares peruanos en el año 2018 / Qualidade de vida relacionada à saúde bucal em pré-escolares peruanos em 2018 / Oral health-related quality of life in peruvian preschool children in 2018

Antecedentes: Existen pocas investigaciones que muestren cómo la caries de aparición temprana (CAT) afecta a la mayoría de los niños peruanos. Sin embargo, es aún menor la cantidad de estudios que muestran cómo la CAT y la necesidad de tratamiento (NTx) afectan la calidad de vida de los menores. Objetivo: Evaluar el impacto de la salud bucal sobre la calidad de vida según CAT y NTx en preescolares del Perú. Materiales y métodos: Se realizó un estudio descriptivo-transversal conformado por una muestra de 360 niños de 3 a 5 años de una institución educativa pública del distrito de Independencia, en Lima. Los niños fueron examinados con el índice CEOD, NTx y el cuestionario de Escala de impacto de la salud oral en infancia temprana (ECOHIS). Los datos fueron analizados con estadística descriptiva y para relacionar se usó ANOVA y Kruskal Wallis (p<0,05). Resultados: La prevalencia de CAT fue de 73,6% y la NTx más requerida fue la "obturación superficial". Se encontraron diferencias estadísticamente significativas tanto para CAT como para NTx en relación con todos los dominios de calidad de vida. Conclusiones: La CAT y la NTx tienen impacto negativo en la calidad de vida de los preescolares.

Background: Few studies have investigated the effect of early childhood caries (ECC) on Peruvian children; there are even fewer studies of how ECC and treatment needs (TNs) affect the quality of life of these children. Objective: To assess the impact of oral health on the quality of life, according to ECC and TNs, of Peruvian preschool children. Materials and methods: A descriptive cross-sectional study was conducted, consisting of a sample of 360 children aged 3 to 5 years from a public educational institution in the district of Independencia, Lima. The children were examined using the decayed, missing, and filled teeth (DMFT) index, the TNs index, and the early childhood oral health impact scale (ECOHIS) questionnaire. The data were analyzed with descriptive statistics using ANOVA and the Kruskal-Wallis test to establish relationships (p <0.05). Results: The prevalence of ECC was 73.6%, and the most required TN was "surface filling." Statistically significant differences were found for both ECC and TNs in relation to all quality of life domains. Conclusions: ECC and TNs have a negative impact on the quality of life of preschool children.

Surgical excision of mucocele with local anesthesia in an 8-month-old baby / Excisão cirúrgica de mucocele sob anestesia local em um bebê de 8 meses de idade

Mucoceles are common disorders of the minor salivary glands, occurring specially on the lower lip. Their occurrence in newborn babies has rarely been reported. In addition, the surgical removal of oral lesions in babies has often been performed with general anesthesia, which option is usually related to the patients' ages, irrespective of the lesion's size and the access to anatomic region where it is located. The present report, however, details the treatment of a mucocele excision performed in an 8-month-old baby with local anesthesia. This case illustrates well that knowledge of the lesion and dentist's experience in the attendance of babies is important, as often only conservative treatment with local anesthesia is required. Therefore, clinicians and parents should be reassured that early surgical intervention under local anesthesia will provide a swift and satisfactory resolution to the problem.

Mucocele é uma ocorrência comum nas glândulas salivares menores, que acontece, principalmente, no lábio inferior. Em bebês, tem sido raramente reportada na literatura. Em adição, a remoção cirúrgica de lesões orais em bebês tem sido realizada sob anestesia geral, cuja opção geralmente se refere à idade do paciente, sem ter relação com o tamanho da lesão e o acesso à região anatômica onde está localizada. O presente caso clínico, no entanto, descreve a excisão da mucocele realizada em um bebê de 8 meses de idade, sob anestesia local. Esse caso ilustra bem que o conhecimento da lesão e a experiência do dentista no atendimento de bebês é muito importante, já que somente um tratamento conservador sob anestesia local é necessário. Portanto, clínicos e pais devem ser alertados para o fato de que uma intervenção cirúrgica precoce sob anestesia local irá proporcionar uma resolução rápida e satisfatória do problema.

Knowledge and attitude of parents or caretakers regarding transmissibility of caries disease.

Dental caries is a transmissible infectious disease in which mutans streptococci are generally considered to be the main etiological agents. Although the transmissibility of dental caries is relatively well established in the literature, little is known whether information regarding this issue is correctly provided to the population. The present study aimed at evaluating, by means of a questionnaire, the knowledge and usual attitude of 640 parents and caretakers regarding the transmissibility of caries disease. Most interviewed adults did not know the concept of dental caries being an infectious and transmissible disease, and reported the habit of blowing and tasting food, sharing utensils and kissing the children on their mouth. 372 (58.1%) adults reported that their children had already been seen by a dentist, 264 (41.3%) answered that their children had never gone to a dentist, and 4 (0.6%) did not know. When the adults were asked whether their children had already had dental caries, 107 (16.7%) answered yes, 489 (76.4%) answered no, and 44 (6.9%) did not know. Taken together, these data reinforce the need to provide the population with some important information regarding the transmission of dental caries in order to facilitate a more comprehensive approach towards the prevention of the disease.
