Association between sociodemographic factors and noncavitated and cavitated caries lesions in 8- to 12-year-old Mexican schoolchildren.

ABSTRACT: The aim of this study was to evaluate the association between sociodemographic factors and noncavitated and cavitated caries lesions in Mexican schoolchildren.This cross-sectional study was conducted in 2020 on 8-to-12-year-old schoolchildren of different socioeconomic status (SES). The caries was evaluated using ICDAS II, SES was evaluated using three categories---a high, middle, or low-income level---of the CONAPO. Multinomial logistic regression analyses were performed in order to ascertain the associations between socioeconomic factors and noncavitated and cavitated caries lesions.The prevalence of noncavitated lesions was 38.0% and cavitated lesions was 43.4% in permanent dentition. In all the samples, 50.6% of schoolchildren had poor oral hygiene. About 52.5% of the mothers and 64.7% of the fathers had less than 9 years of education. Schoolchildren with a low-income level have more cavitated lesions (ICDAS II 4-6) than schoolchildren with high-income level (56.3% vs 15.8%, P = .009). The multinomial logistic regression models showed that mother's level of education <9 years and low-income level were significantly associated with cavitated caries lesions (ICDAS II 4-6), [odds ratio = 1.79 (1.17 - 2.75); P = .007], [OR = 2.21 (1.23 - 3.97); P = .008], respectively. The socioeconomic level was not associated with noncavitated caries lesions (ICDAS II 1-3).An association was found between the presence of cavitated caries lesions and the subject's mother's level of education and a low-income level. Socioeconomic factors were found to be associated with inequalities in caries distribution in the age group studied.

Untreated cavitated dentine lesions: impact on children's quality of life.

The aim of the present investigation was to assess the impact of dental caries prevalence and the consequences of untreated cavitated dentine lesions on quality of life of 6- and 7-year-old Brazilian children. A total of 826 schoolchildren were assessed using ICDAS and pufa (to score consequences of dental caries on soft tissues) indices. History of extraction and toothache was recorded. Oral health-related quality of life was assessed using the Brazilian version of the Early Childhood Oral Health Impact Scale (B-ECOHIS). A multiple logistic regression model was used to analyze the relationship between the prevalence of dentine carious lesions, pufa, history of extraction and toothache with the B-ECOHIS scores. A total of 587 questionnaires were analyzed. The prevalence of cavitated dentine lesions and pufa was 74.8 and 26.2%, respectively. Some 21.8% of children reported toothache and 9.2% had had at least one tooth extraction. The chance (OR) for children with cavitated dentine lesions, pufa ≥1, history of extraction and toothache of having higher B-ECOHIS scores than those not affected was 1.90 (95% CI: 1.18-3.06), 6.26 (95% CI: 3.63-10.83), 6.87 (95% CI: 2.75-17.16) and 3.68 (95% CI: 2.12-6.39), respectively. Children's quality of life was negatively influenced by untreated cavitated dentine lesions and their consequences.

Recovering the function and esthetics of fractured teeth using several restorative cosmetic approaches. Three clinical cases.

The teeth most commonly affected by trauma are the maxillary central incisors. The most frequent types of traumatic dental injuries to permanent teeth are enamel fractures, enamel and dentine fractures, and enamel and dentine fractures with pulp involvement. This article describes three clinical cases with different levels of traumatized maxillary incisors and several cosmetic approaches for recovery of the esthetics and the masticatory function, as well as the social/psychological aspects of treatment. All cases involved young adult men. The three clinical cases involve dentin and enamel fractures, dentin and enamel fractures with pulp exposure, and dentin and enamel fractures with pulp exposure associated with root fracture. The cosmetic treatments used to resolve fractures were direct composite resin by layering technique, indirect all-ceramic restorations (laminate veneer and ceramic crowns over the teeth), and immediate implant after extraction followed by immediate loading (ceramic abutments with ceramic crown over implant). In all three cases, excellent functional and esthetic results were achieved by use of these treatment modalities. The patients were very satisfied with the results.

Reattachment of anterior teeth fragments using a modified Simonsen's technique after dental trauma: report of a case.

This is a case report of a 9-year-old boy with complicated crown fractures of two traumatized teeth: left maxillary central and lateral incisors. The central incisor presented a small pulpal exposure of approximately 1 mm and the lateral incisor had an ulcerated and exposed pulp. Endodontic management included direct pulp capping, partial pulpotomy, and restorative management including reattachment of the teeth fragments using a modified Simonsen's technique. The reattached fragments were assessed clinically and radiographically at 12 months. The teeth remained vital, there were no color changes, and the restorations had an acceptable appearance.

Occurrence of talon cusp on a geminated maxillary central incisor: a case report.

This article reports an uncommon case of talon cusp on a geminated permanent maxillary central incisor, including details of the clinical and radiographic findings and treatment. A 28-year-old woman presented at the university dental clinic, and intraoral examination revealed a maxillary central incisor of abnormal size with a prominent accessory cusp on the lingual aspect. The case was diagnosed as talon cusp on a geminated tooth. Early diagnosis of this anomaly is important since it may cause clinical problems such as esthetic concerns, caries and tooth crowding. In the present case, these anomalies did not complicate the subsequent endodontic treatment.

Partial pulpotomy and tooth reconstruction of a crown-fractured permanent incisor: a case report.

Pulp exposure due to traumatic injuries in the anterior permanent teeth of adolescents is a common occurrence. A vital permanent maxillary incisor with complex crown fracture and pulp exposure was treated by partial pulpotomy and assessed clinically through pulpal sensitivity tests and radiographically for periapical healing. Partial pulpotomy consisted of pulp tissue removal to a depth of only 1 to 2 mm, then capping the pulpal wound with calcium hydroxide, lining with resin-modified glass-ionomer cement, and restoration with resin composite. At each recall (7, 15, 21, 50, 90, 150, and 250 days), no spontaneous pain was observed; the pulp showed signs of vitality and absence of periapical radiolucency after 90 days. For long-term success, partial pulpotomy is recommended as an option for cases of traumatic pulp exposure in permanent incisors with crown fractures.

Dental anomaly: dens evaginatus (talon cusp).

Dens evaginatus is a developmental anomaly characterized by the occurrence of an extra cusp shaped as a tubercle projecting from the palatal or buccal surfaces (talon cusp). In the anterior dentition, dens evaginatus is more commonly found in the maxilla and on the palatal surface of the tooth. The authors present a case of dens evaginatus in a maxillary central incisor, in which the evagination was removed and routine endodontic treatment was performed.

Necesidad o no del uso de colorantes durante la remoción de la dentina cariada: soporte microbiológico / Caries detector dye, its use during dentinal caries removal: microbiological support

La remoción completa de la dentina cariada es un proceso complejo, por la escasa definición de criterios objetivos para diferenciar la dentina infectada de la afectada. Una de las formas de reducir la subjetividad es la utilización de colorantes, aunque existe controversia respecto a las indicaciones, ventajas y desventajas de su uso. Este estudio comparó la efectividad de la técnica convencional óptica y táctil con la utilización de rojo ácido al 1 por ciento en la remoción de la dentina cariada, y microbiológicamente cuantificó y clasificó los microorganismos de la dentina remanente, en 34 pacientes con caries moderada. Se encontró que el 97 por ciento de las cavidades presentaron tinción de la dentina, siendo más frecuente ésta en la pared pulpar y unión amelodentinaria, pero el colorante no siempre tiñó bacterias, por lo cual llevó a remoción innecesaria de dentina y a varias exposiciones pulpares. El 61.81 por ciento del total de los microorganismos cultivables no se logró indentificar y su papel en el progreso de la caries no se conoce. Los S. mutans y Lactobacillus representaron sólo el 12.79 por ciento del total de los microorganismos. No se encontró correlación entre el frente de decoloración, el sitio de tinción y el frente bacteriano
