Impact of oral diseases and disorders on oral health-related quality of life of preschool children.

BACKGROUND The presence of oral diseases and disorders can produce an impact on the quality of life of preschool children and their parents, affecting their oral health and well-being. However, socioeconomic factors could confound this association, but it has not been yet tested at this age. OBJECTIVE To assess the impact of early childhood caries (ECC), traumatic dental injuries (TDI) and malocclusions on the oral health-related quality of life (OHRQoL) of children between 2 and 5 years of age adjusted by socioeconomic factors. METHODS Parents of 260 children answered the Early Childhood Oral Health Impact Scale (ECOHIS) (six domains) on their perception of the childrens OHRQoL and socioeconomic conditions. Two calibrated dentists (κ>0.8) examined the severity of ECC according to dmft index, and children were categorized into: 0=caries free; 1-5=low severity; ≥6=high severity. TDI and malocclusions were examined according to Andreasen & Andreasen (1994) classification and for the presence or absence of three anterior malocclusion traits (AMT), respectively. OHRQoL was measured through ECOHIS domain and total scores, and poisson regression was used to associate the different factors with the outcome. RESULTS In each domain and overall ECOHIS scores, the severity of ECC showed a negative impact on OHRQoL (P<0.001). TDI and AMT did not show a negative impact on OHRQoL nor in each domain (P>0.05). The increase in the childs age, higher household crowding, lower family income and mother working out of home were significantly associated with OHRQoL (P<0.05). The multivariate adjusted model showed that the high severity of ECC (RR=3.81; 95% CI=2.66, 5.46; P<0.001) was associated with greater negative impact on OHRQoL, while high family income was a protective factor for OHRQoL (RR=0.93; 95% CI=0.87, 0.99; P<0.001). CONCLUSIONS The severity of ECC and a lower family income had a negative impact on the OHRQoL of preschool children and their parents.

Impact of traumatic dental injuries and malocclusions on quality of life of young children

BackgroundThe presence of traumatic dental injuries and malocclusions can have a negative impact on quality of life of young children and their parents, affecting their oral health and well-being. The aim of this study was to assess the impact of traumatic dental injuries and anterior malocclusion traits on the Oral Health-Related Quality of Life (OHRQoL) of children between 2 and 5 years-old.MethodsParents of 260 children answered the six domains of the Early Childhood Oral Health Impact Scale (ECOHIS) on their perception of the OHRQoL (outcome). Two calibrated dentists assessed the types of traumatic dental injuries (Kappa = 0.9) and the presence of anterior malocclusion traits (Kappa = 1.0). OHRQoL was measured using the ECOHIS. Poisson regression was used to associate the type of traumatic dental injury and the presence of anterior malocclusion traits to the outcome.ResultsThe presence of anterior malocclusion traits did not show a negative impact on the overall OHRQoL mean or in each domain. Only complicated traumatic dental injuries showed a negative impact on the symptoms (p = 0.005), psychological (p = 0.029), self image/social interaction (p = 0.004) and family function (p = 0.018) domains and on the overall OHRQoL mean score (p = 0.002). The presence of complicated traumatic dental injuries showed an increased negative impact on the childrens quality of life (RR = 1.89; 95% CI = 1.36, 2.63; p < 0.001).ConclusionsComplicated traumatic dental injuries have a negative impact on the OHRQoL of preschool children and their parents, but anterior malocclusion traits do not.

Predictive factors for pulp necrosis in traumatized primary incisors: a longitudinal study

BACKGROUND This study aimed to assess factors associated with occurrence of pulp necrosis (PN) in traumatized primary incisors, which may contribute to the prognosis of this outcome. DESIGN Data were collected by single examiner through the analysis of clinical files of traumatized patients. The occurrence of PN in traumatized teeth was the evaluated outcome. Poisson regression analysis was applied to calculate the relative risk (RR) and the respective 95% confidence interval. RESULTS Five hundred and twenty-one files were assessed, summing up 727 traumatized primary incisors. The proportion of teeth affected by PN was 23.8%. Multiple regression analysis indicated the following factors as positively associated with PN: trauma with displacement, pulp exposure fracture, self-report of pain, yellow, grey and brown crown discoloration, internal root resorption, and bone loss. Trauma in 4- to 5-year old and more than 5-year-old children, pulp canal obliteration, and external root resorption with bone formation were negatively associated with PN. CONCLUSIONS Teeth that suffered more aggressive injuries, pain, some types of discoloration, and other radiographic findings (for instance, internal root resorption) are positively associated with the occurrence of PN. On the other hand, trauma in older children, canal obliteration, or external resorption show less probability of PN.

Does the Decline in Caries Prevalence of Latin American and Caribbean Children Continue in the New Century? Evidence from Systematic Review with Meta-Analysis

Objective To carry out a systematic review with meta-analysis of prevalence of caries in Latin America and Caribbean children considering studies performed in this new century. Methods Two reviewers searched PubMed, Embase, LILACS and governmental databases through May 2016 to identify papers published in English, Portuguese or Spanish. Studies in those countries performed with 5–6 or 11–13 year-old children and that presented separate prevalence figures from primary and permanent teeth were selected. We performed a descriptive analysis of studies and meta-analysis to calculate the overall prevalence and 95% confidence intervals (95% CI) in both primary and permanent teeth. We also analyzed the trends of prevalence of caries through the years and influence of other variables on caries prevalence using multilevel analysis. Results Seventy-five studies were included from the 1,306 articles initially retrieved. The meta-analysis of caries prevalence grouped for Latin American and the Caribbean countries were highly different from Brazil and other investigated countries for primary teeth (5–6 years-old—Brazil: 0.52, other countries:0.70) and permanent teeth (11–12 years-old—Brazil: 0.56, other countries: 0.63). For studies conducted only in Brazil the prevalence was significant lower for primary but not for permanent teeth. In Brazil, a downward trend of caries prevalence was observed in 11-13-year-old children. Conclusion Despite the decline of caries prevalence in permanent teeth, mainly in Brazil, the disease still affects more than half of the children population in Latin American and Caribbean countries in the 21st Century.

Pulp polyp in traumatized primary teeth – a case–control study

AIM To assess clinical characteristics and other factors associated with the occurrence of pulp polyp in traumatized primary teeth as well to evaluate the impact of pulp polyp occurrence on clinical decision-making after traumatic injuries. MATERIAL AND METHODS This study was divided into three phases. First, occurrence and clinical characteristics of pulp polyp were assessed followed by a descriptive analysis and categorical tests of association. Secondly, a case-control design was used, and the occurrence of pulp polyp was set as the outcome. In third phase, the occurrence of pulp polyp after fracture with pulp exposure was investigated as a variable possibly associated with clinical decision-making (dental extraction/endodontic treatment). Logistic regression analyses were used, and odds ratios and 95% confidence interval (OR; 95% CI) were calculated in second and third phases. RESULTS Occurrence of pulp polyp in traumatized primary teeth was of 2.3%. Hyperplastic tissue color and proliferation size were not associated with the time to seek treatment after injury (P > 0.05). Children up to 2 years of age had more chance of having pulp polyp in comparison with older children (3.15; 1.15-8.64). Teeth with crown-root fracture had more chance of dental extraction in the therapeutic approach than the teeth with only crown fracture (4.36; 1.10-17.32). Presence of pulp polyp was not associated with the treatment carried out. CONCLUSIONS Occurrence of pulp polyp in traumatized primary teeth is not frequent and is associated with the age when traumatic dental injury occurs but does not interfere directly with the therapeutic approach.

Mucocele of the lower lip in a 1-year-old child

Mucocele is a common oral mucosal lesion, but it is rarely observed in the infant. The aim of this study is to present the case report of a 1-year-old male patient, with a mucocele of the lower lip, describing the clinical characteristics and surgical treatment performed under local anesthesia with no recurrence observed after nine months follow-up, and also to show the histological features of this benign oral lesion.

Pulp Calcification in Traumatized Primary Teeth – Classification, Clinical And Radiographic Aspects

OBJECTIVE The aim of this study was to standardize the nomenclature of pulp alteration to pulp calcification (PC) and to classify it according to type, quantity and location, as well as relate it to clinical and radiographic features. STUDY DESIGN The dental records of 946 patients from the Research and Clinical Center for Dental Trauma in Primary Teeth were studied. Two hundred and fifty PC-traumatized upper deciduous incisors were detected. RESULTS According to radiographic analysis of the records, 62.5% showed diffuse calcification, 36.3% tube-like calcification, and 1.2% concentric calcification. According to the extension of pulp calcification, the records showed: 80% partial calcification, 17.2% total coronal calcification and partial radicular calcification, and 2.8 % total coronal and radicular calcification. As for location, only 2.4% were on the coronal pulp, 5.2% on the radicular pulp and 92.4% on both radicular and coronal pulp. Regarding coronal discoloration, 54% were yellow and 2% gray. In relation to periradicular changes, 10% showed widened periodontal ligament space, 3.1% internal resorption, 10% external resorption, 10.4% periapical bone rarefaction. CONCLUSIONS Since PC is a general term, it is important to classify it and correlate it to clinical and radiographic changes, in order to establish the correct diagnosis, treatment and prognosis of each case.

Giant Cell Fibroma in a Two-Year-Old Child

The giant cell fibroma is a benign nonneoplastic fibrous tumor of the oral mucosa. It occurs in the first three decades of life in the mandibular gingiva, predominantly, showing predilection for females. This article reports a case of giant cell fibroma in a 2-year-old girl, which is an uncommon age for this lesion. The patient was brought for treatment at the Research and Clinical Center of Dental Trauma in Primary Teeth, where practice for the Discipline of Pediatric Dentistry (Faculty of Dentistry, University of São Paulo, Brazil) takes place. During clinical examination, a tissue growth was detected on the lingual gingival mucosa of the lower right primary incisors teeth. The lesion was excised under local anesthesia and submitted to histological examination at the Oral Pathology Department of the Faculty of Dentistry, University of São Paulo, which confirmed the diagnosis of giant cell fibroma. There was no recurrence after 20 months of monitoring. This instance reinforces the importance of oral care from the very first months of life in order to enable doctors to make precocious diagnosis and offer more appropriate treatments for oral diseases, as well as to promote more efficient oral health in the community.

Endodontic and restorative treatment of fused primary anterior teeth — Case report

Fused teeth present a high predisposition to caries, which occurs due to the possibility of bacterial plaque accumulation in the fissures or grooves in the union between the teeth involved. This paper reports the case of a 2-year-old boy presented with a fused left maxillary central and lateral incisors which crown was destroyed by caries, and the endodontic and composite resin based restorative treatment performed, that restored aesthetics, function and preserved the primary teeth in the dental arch until their natural exfoliation.

Variability in the proportion of components of iodoform-based Guedes-Pinto paste mixed by dental students and pediatric dentists

OBJECTIVE Guedes-Pinto paste (GPP) is an iodoform paste used in most dental schools in Brazil. The paste is a composite of medicines (Rifocort , camphorated paramonochlorophenol [PMCC], and iodoform) used for endodontic treatment of primary teeth. The aim of this study was to evaluate the proportion variability of GPP components when mixed by undergraduate dentistry students and pediatric dentists. MATERIALS AND METHODS The study was divided into 4 groups: G1 (15 undergraduate students), G2 (15 specialists in Pediatric Dentistry), G3 (15 professors with clinical activity), and G4 (7 professors-researchers). All volunteers prepared GPP according to the original specifications: the same visual proportion for each component. The components were weighed using an analytical balance and the percentage was calculated. RESULT After normality (Kolmogorov-Smirnov) and homogeneity tests (Levene test), the data were submitted to analysis of variance and intraclass correlation coefficient tests (P<0.05). The percentage means of each respective group were as follows: Rifocort 20.2%, 20.8%, 26.7%, 27.3%; camphorated PMCC 9.2%, 8.1%, 6.7%, 5.1%; and the iodoform 70.6%, 71.1%, 64.7%, 67.6%. There were no significant differences between groups for the component percentages. There was a high intraclass correlation coefficient (G1 0.945; G2 0.951; G3 0.921; and G4 0.870). CONCLUSION The proportion of GPP was similar in all the groups, allowing us to conclude that ideal GPP proportion, based on the entire group mean, was 23.8% of Rifocort® ; 7.0% of camphorated PMCC; and 69.2% of iodoform.
