RSBO , 2011,
Abstract: Introduction: One of the most common sequelae observed after dental trauma is root resorption. Objective: The aim of this study was to classify and discuss the external root resorption after a dental trauma, based on a literature review. Literature review: A bibliographic search was performed in the following databases: Medline, PubMed, and Lilacs, from 1997 to 2010. The following descriptors were used: Root resorption, Dental trauma and Classification. From a total of 152 articles found, 25 were selected: 24 in English and 1 in Spanish. Classic articles were also used in our study. External root resorption after dental traumas can be divided into superficial, inflammatory and replacement. It can also be verified in primary dentition as physiological and atypical resorptions. Conclusion: Each type of resorption presents clinical features as well as radiographic and histological aspects. Therefore, the dentist should know these characteristics to perform an early diagnosis and appropriate treatment, minimizing the sequelae related to this problem. Moreover, in primary dentition, the differential diagnosis between physiological and pathological resorption is important to avoid over-treatment.
Sequelae of Trauma to Primary Dentition
Pesquisa Brasileira em Odontopediatria e Clínica Integrada , 2006,
Abstract: Objective: The aim of this study was to determine the presence of clinical and radiographic signs of injury to the maxillary primary incisors and the children carers' knowledge about dental trauma ocurrence in a 45 children group from three to eight years old. Method: Before the clinical examination, the carers were asked about their children's dental trauma events. After that, took course the maxillary incisors clinical and radiographical examination, excluding the ones with caries, fillings, or pulpar treatments. Results: Discoloration (50.0%) was the most common present sign of trauma followed by avulsion (17.6%) and the pulp canal obliteration (56.3%) was the major result of the radiographical signal. Boys had more trauma recorded than girls and the maxillary central incisors were the most vulnerable to injury. Besides, the amount of trauma recorded by clinical and radiographic examination was bigger than that reported in the questionnaire by mothers or children carers. Conclusion: The results related in this study reinforce the need of immediate attention to trauma on deciduous dentition and long term observation of the developing permanent successor.

Abstract: The treatment of children presenting dental trauma in the primary dentition requires a different approach from that used in the permanent dentition, because there is a very close relation between the apex of the traumatized primary tooth and the successor permanent bud. The possible consequences on the permanent teeth should be considered when performing early treatment in order to prevent further damage. Also, the probable trauma’s late sequelae should be taken into account both for primary and permanent dentition. Given the subject’s importance, this chapter aimed to report this issue broadly. This comprises the anamnesis, general, intraoral, and radiographic examination and the comprehensive treatment of the patient. Additionally to the classification of dental injuries, we highlighted the diagnosis, required treatment,prognosis, and follow-up of each clinical situation. A topic on soft tissue lesion was included, because it has a great impact on both the child and family. Moreover, it could be associated with other trauma types. Since the analysis of the child’s vaccination status is suggested, in face of cases demanding that tetanus vaccine be valid, the recommendation of the Brazilian Ministry of Health was also informed. Furthermore, there is an item on dental splinting, parenting advice, and trauma consequences on primary and successor permanent teeth. At the end of the chapter, two tables summarize the early and delayed treatment of trauma involving primary tooth’s enamel, dentin, pulp, and supportive tissues.

RSBO , 2012,
Abstract: Introduction: Dental trauma to primary teeth or to the jaws may cause disorders on the development of permanent successor teeth. The alterations may either occur at the time of accident or be caused by post-traumatic consequences. Objective: The aim of this paper is to present cases of alterations on permanent dentition following dental trauma to primary teeth. Case reports: Three cases are presented in this paper. The severity of the post-traumatic sequels shown by the permanent teeth kept a direct relationship with the extent of the impact and patient’s age at the accident. These sequels resulted in whitish or brownish opacities, enamel hypoplasia, root dilacerations, and total arrest of root development. Conclusion: It can be concluded that the protocols for patients who had experienced dental trauma must observe a systematic clinical and radiographic follow-up as well as alternatives of treatment for the primary and permanent teeth involved. Prognostics and treatments related to the sequels in permanent teeth may be obtained from a close analysis of clinical and radiographic aspects, avoiding more damages to the stomatognathic system. The severity of the sequels is directly related to the degree of permanent tooth formation (child’s age), type of dental trauma and extent of the impact.

Abstract: Caries has traditionally been assessed with WHO criteria including only obvious caries lesions. ICDAS has been developed to detect also the enamel caries lesions. This study aims to study caries and the associations of the number of caries lesions between the permanent and primary molars with ICDAS in the mixed dentition of the first and second grade primary school children. The clinical examinations of 485 children were conducted by four examiners with high reproducibility (inter- and intraexaminer kappas >0.9). The mean number of caries lesions—especially dentine caries—seemed to be higher in the second primary molars than in the first permanent molars. There were significant correlations between the number of lesions on occlusal and lingual surfaces between the primary and permanent molars. Enamel caries lesions, restorations, and caries experience did not increase according to age. Therefore, caries might be increasing in this population. As a conclusion, ICDAS recording seems to give appropriate information from the occurrence of caries lesions and its correlations between the primary and permanent teeth and surfaces. 1. Introduction Reliable, reproducible, and practical detection and assessment of dental caries lesions as an outcome of dental caries disease has been a challenge for a long time [1, 2]. The lesions can be detected on all surfaces of the primary, permanent, and mixed dentitions. Surface lesions can then be counted according to the type of the teeth (incisors, canines, premolars, and molars) or according to the surfaces (occlusal, proximal, and free smooth surfaces). Mixed dentition stage normally includes the age groups from 6 to 12 years, when the permanent teeth are erupting and the primary teeth exfoliating. The exfoliation is a special problem in the prospective clinical caries trials, when the tooth and surfaces need to be present in both of the examinations. However, also cross-sectional clinical studies can still give important descriptive information for monitoring the trends and for giving dental health a visibility for policy makers [3]. The mixed dentition is the first stage to study an association of the number of caries lesions between the primary and permanent teeth. Several studies have shown very clear correlations in caries experience between the primary and permanent teeth [4–9]. Traditionally, caries has been measured by DMFT/S index, where only teeth or surfaces with cavitated lesions extending into the dentine have been counted [10, 11]. Over the years, DMFT index has been criticized for several reasons

Abstract: The purpose of the study was to assess the pattern of prevalence of dental caries in the primary dentition among 5 year old children. The area of study was urban Pondicherry and the study population consisted of 1009 school children of both sexes (527 boys and 482 girls). A simple random sampling method was used to select the schools. Dental caries was assessed by the Dentition status and Treatment Need (WHO 1997). Statistical analysis was done using the Proportion test. The prevalence of caries was 44.4% among the study population, being higher in the boys (P < 0.05); In Mandibular arch in both the sexes (boys P < 0.05, girls P < 0.01); in posterior teeth (both sex wise & arch wise). Comparison of caries among anterior teeth (Boys vs Girls) [corrected] and posterior teeth (upper vs. lower) revealed higher caries prevalence in Maxillary anterior teeth (P < 0.001) and Mandibular posterior teeth (P < 0.001). In both the sexes and arches, primary second molars showed higher caries prevalence.

Abstract: Objective: There are various risk factors which play an essential role in the multifactorial disease “dental caries.” Although absence of interdental spaces in the primary dentition may increase the risk of dental caries, not many studies have been carried out to assess this correlation. This study was performed to assess the relationship between interdental spacing and dental caries in primary dentition.Materials and Methods: Five hundred 4-6 year-old children were enrolled into this study. Dental caries was recorded using the criteria given by Warren et al. Following this, impressions were made for the upper and lower arches and dental casts were poured. Interdental spaces were measured on the dental casts using a digital verniercaliper. The data obtained were subjected to statistical analysis.Results: The number of sites with interdental spaces was higher in the maxillary arch in comparison to the mandibular arch. The highest number of interdental spaces was observed between the maxillary anteriors. The number of demineralized, but non-cavitated tooth surfaces (d1)were higher than the number of cavitated tooth surfaces. This difference was significant in the mandibular anterior segment. Dental caries showed a negative correlation with interdental spacing. A significant correlation was found between dental caries and interdental spacing in the posterior segment of the mandibular arch.Conclusion: This study showed that children with no interdental spacing in the primary dentition are at higher risk for dental caries.

Abstract: The aim of this study was to investigate factors associated with caries experience in the primary dentition of one- to five-year-old children with cerebral palsy. A total of 266 dental records were examined, and caries experience was measured by dmft. The following variables were also analyzed: gender, oral hygiene, history of gastroesophageal reflux, use of medications for gastroesophageal reflux, gingival status, sugar intake and reports of polyuria, excessive thirst and xerostomia. For analysis purposes, the individuals were categorized as those with and without caries experience and subcategorized into the following age groups: one year; two to three years; and four to five years. After bivariate analysis, variables with a p-value < 0.25 were selected for incorporation into the Poisson regression models. Considering the limitations of the protocol, the level of oral hygiene perceived on the first appointment was the only factor associated with caries experience among two-to-fiveyear-old children with cerebral palsy.

Case Reports in Dentistry , 2012, DOI: 10.1155/2012/614652
Abstract: Supernumerary teeth are considered as one of the most significant dental anomalies during the primary and early mixed dentition stages. They are of great concern to the dentists and parents because of the eruption, occlusal, and esthetic problems they can cause. Supernumerary teeth occur more frequently in the permanent dentition but rarely in primary dentition. Mesiodens is the most common type of supernumerary teeth but rarely seen in lower arch. Early recognition and diagnosis of supernumerary teeth is important to prevent further complications in permanent dentition. Four cases of supernumerary teeth with mesiodens in upper and lower arch in primary dentition and their management have been discussed.
