Low-Level Laser Therapy for Management of Hypersensitivity in Molar-Incisor Hypomineralization and Oral Health-Related Quality of Life: Case Report.

The aim was to report the use low-level laser therapy (LLLT) in the management of hypersensitivity in an adolescent with molar incisor hypomineralization (MIH) and the impact of LLLT on his oral health-related quality of life (OHRQoL). Clinical examination revealed severe MIH with hypersensitivity, in all first permanent molars and incisors. The treatment proposed was desensitization with fluoride and esthetic rehabilitation of the affected teeth. Then, LLLT was applied perpendicularly in a continuous mode (wavelength of 808 nm, power of 100 mW, dose of 1 J, and fluence of 35 J/cm2). The visual analogue scale was applied each session of LLLT. The child perceptions questionnaire (CPQ11-14) was administered at the beginning and the end of the treatment. It was concluded that LLLT can be indicated in the management of hypersensitivity in an adolescent with severe MIH to control pain and to improve his OHRQoL.

Overweight/obese children are associated with lower caries experience than normal-weight children/adolescents.

AIM: To compare (a) enamel carious (EC) and dentin carious (DC) lesions and (b) caries risk, between normal-weight (NW) and overweight/obese (OW) children/adolescents. DESIGN: In this cross-sectional study, 91 participants aged 6-12 years were classified according to the body mass index (BMI): NW (n = 50) and OW (n = 41). Caries experience was evaluated using the International Caries Detection and Assessment System (ICDAS) with two thresholds: "EC/DC" (ICDAS 1-3/4-6) and "DC" (ICDAS 4-6). Caries risk was determined by the Caries Management by Risk Assessment (CAMBRA) system. A logistic regression analysis was performed to determine the association among OW, caries thresholds, and caries risk. RESULTS: Caries experience was similar for both groups at the "EC/DC" threshold (P = .477) and higher for the NW group at the "DC" threshold (P = .009). For CAMBRA, caries risk classification was similar for both groups (P = .082). The logistic regression showed the OW group was less likely to exhibit radiographically visible proximal carious lesions (odds ratio [OR] of 0.330, P = .019), thick biofilm visible on the tooth surface (OR = 0.360, P = .019), high caries risk (OR = 0.367, P = .039), and moderate-to-high caries levels (OR = 0.190, P = .022). CONCLUSION: OW children/adolescents had lower caries experience, at both ICDAS thresholds, and lower caries risk, compared to NW children/adolescents.

Inflammatory markers in saliva as indicators of gingival inflammation in cerebral palsy children with and without cervical motor control.

AIM: To evaluate the relation among gingival inflammation, salivary osmolality, levels of IL-1ß, IL-6, IL-8, TNF-α, and s-IgA concentrations in children with spastic CP with or without cervical motor control in a cross-sectional study. DESIGN: Unstimulated whole saliva and the gingival index were collected in 37 and 34 CP children with and without cervical motor control, respectively. The data were dichotomized as follows: (=0) absence of gingival inflammation and (≥0.1) presence of gingival inflammation. RESULTS: The group without cervical control presented statistically higher mean values of salivary osmolality, s-IgA, and cytokines. In addition, statistically positive correlation between the gingival index and salivary cytokines was observed in the group with cervical control. Salivary osmolality, salivary cytokines, and s-IgA from both groups presented a significant positive correlation. Significant differences (P = 0.00336) in the values of salivary osmolality were observed between the CP individuals with (93.9 ± 32.7) and without gingival inflammation (74.4 ± 16.6). ROC analysis was performed, and values of salivary osmolality >80 indicated a sensitivity of 0.54 and a specificity of 0.79. CONCLUSIONS: Children without cervical motor control presented a more pronounced oral inflammatory status that was characterized by higher levels of cytokines.

Gingivitis and salivary osmolality in children with cerebral palsy.

AIM: To investigate the influence of salivary osmolality on the occurrence of gingivitis in children with cerebral palsy (CP). DESIGN: A total of 82 children with spastic CP were included in this cross-sectional study. Oral motor performance and gingival conditions were evaluated. Unstimulated saliva was collected using cotton swabs, and salivary osmolality was measured using a freezing point depression osmometer. Spearman's coefficient, receiver operating characteristic (ROC), and multiple logistic regression analyses were performed. RESULTS: Strong correlation (r > 0.7) was determined among salivary osmolality, salivary flow rate, visible plaque, dental calculus, and the occurrence of gingivitis. The area under the ROC to predict the influence of salivary osmolality on the occurrence of gingivitis was 0.88 (95% CI 0.81-0.96; P < 0.001). The cutoff value of 84.5 for salivary osmolality presented good sensitivity and specificity, both higher than 77%. The proportion of children presenting salivary osmolality ≤84.5 mOsm/kgH2 O and gingivitis was 22.5%, whereas for the group presenting osmolality >84.5 mOsm/kgH2 O, the proportion of children with gingivitis was 77.5%. Salivary osmolality above 84.5 increased the likelihood of gingivitis fivefold, whereas each additional 0.1 mL of salivary flow reduced the likelihood of gingivitis by 97%. CONCLUSION: Gingivitis occurs more frequently in children with CP showing increased values of salivary osmolality.

Oral manifestations of systemic alterations in early childhood.

AIM: This study aimed to describe certain common oral manifestations during early childhood that should be known by the pediatric dental surgeon. BACKGROUND: The correct diagnosis and treatment of oral manifestations during early childhood is important for children's development. The pediatric dentist is responsible for maintaining oral health in children, since they change constantly during their development and growth. CASE REPORT: Four cases of oral lesions are described, in which the diagnosis and related approach for each one is reported. The first was an acute primary herpetic gingivostomatitis, the second, pseudomembranous candidiasis, the third, chickenpox and the last was molluscum. CONCLUSION: Professionals who treat children in this age group must be able to diagnose and treat common oral manifestations when necessary and should refer the child to a pediatrician for effective treatment if the presence of any systemic alteration is suspected. CLINICAL SIGNIFICANCE: Pathognomonic signs of the most common oral manifestations in early childhood should be known by dentists to improve early diagnosis and proper management.

Association of salivary parameters and erosive tooth wear in preschool children.

The aims of this study were to 1) assess the association between erosive tooth wear (ETW) according to the BEWE (Basic Erosive Wear Examination) scoring system and salivary parameters and 2) compare salivary parameters according to ETW severity in the subgroup of children with ETW. This cross-sectional study included 52 preschool children aged 5 years paired by sex. A calibrated examiner assessed ETW using BEWE criteria, and stimulated saliva was collected to determine salivary flow, osmolality, pH, and buffering capacity. The children were divided into two groups: without ETW (n=26; BEWE score 0) and with ETW (n=26; BEWE scores 1 and 2). Logistic regression analysis was used to determine the magnitude of the association between ETW and salivary parameters and estimates of odds ratios (OR). In the unadjusted analysis, the ETW group was more likely to have lower salivary flow (OR = 0.079; 95%CI = 0.013-0.469; p = 0.005) and lower osmolality (OR = 0.993; 95%CI = 0.985-1.000; p = 0.049). In the adjusted analysis, salivary flow remained significantly associated with ETW (OR = 0.087; 95%CI = 0.014-0.533; p = 0.008). Lower salivary osmolality values were observed in ETW, especially in preschool children with more severe ETW (BEWE score 2). Receiver operating characteristic (ROC) determined a salivary osmolality cutoff point of < 201 for the presence of ETW. In conclusion, salivary flow rate was significantly associated with ETW prevalence. Lower values of salivary osmolality were observed in preschool children with distinct erosive lesions with significant loss of tooth structure (BEWE 2).

Gingival inflammation and hematological parameters in children with visceral leishmaniasis: A cross-sectional study.

AIMS: This cross-sectional study aimed to assess gingival inflammation in 67 children aged 1-8 years (mean age 3.07) with visceral leishmaniasis (VL) at the time of hospitalization (D1) and 7 days after the first interview (D7) and compare the main hematological changes between the two time points. METHODS AND RESULTS: The biofilm index was verified at D1 and D7 using the Simplified Oral Hygiene Index (OHI-S) and the gingival inflammation index based on the gingival index (GI), along with hematological parameters. The mean OHI-S was 2.35 ± 0.93 at D1 and 1.47 ± 0.75 at D7. The mean GI was 0.56 ± 0.59 at D1 and 0.11 ± 0.32 at D7. The variable OHI-S at D1 could predict GI at D1, as an increase in the OHI-S value by one unit was associated with an increase in the GI D1 value by 0.36 units (p < .05). Multivariate linear regression analysis showed that none of the hematological variables were predictive of gingival inflammation at D1 and D7. CONCLUSION: Children with VL had poor oral hygiene on the first day of hospitalization. Clinically, the oral hygiene status progressed from poor at D1 to regular at D7. After 7 days the gingival bleeding scores also reduces.

Temporomandibular disorder in individuals with spinal cord injuries.

OBJECTIVE: This study evaluated Temporomandibular Disorder (TMD) in individuals with Spinal Cord Injuries (SCI) compared to individuals without physical disabilities. DESIGN: Cross-sectional. SETTING: International Fair of Technologies in Rehabilitation and Accessibility (REATECH) and School of Dentistry at the University of São Paulo (USP), Brazil. PARTICIPANTS: In total, 19 patients with SCI and 19 patients without SCI (36.9 ± 11.4 years old) were examined by a calibrated examiner. METHODS: using the following parameters: cervical spine mobility, palpation of muscle groups of the head and neck, functional manipulation of the lateral and medial pterygoids, and joint palpation (Diagnostic Criteria). The pattern and amplitude of mandibular movements were determined during screening using the Helkimo index. STATISTICAL ANALYSES: Student's t-test, chi-square, Fisher's exact and Shapiro-Wilk test were used. RESULTS: The groups did not differ in the presence of noise, pain, temporomandibular joint palpation, locking, dislocation, jaw pain, muscle sensitivity, or in pain, mobility of the cervical spine and functional manipulation. With respect to the jaw mobility index, the groups differed in range of movement (P = 0.020) and maximum right lateral movement (P = 0.007), with the worst values in the SCI group. The groups also differed in relation to lateral flexion in cervical mobility, in which the group without SCI presented better results (P = 0.046). CONCLUSION: The Spinal Cord Injuries group showed higher levels of TMD in terms of range of movement, lateral flexion, and maximum right lateral movement, than the individuals without physical disabilities, demonstrating a clinical significance between cervical and mandibular disability in this group.

Prevalence of dental trauma in individuals with special needs.

BACKGROUND: Individuals with special needs exist throughout the world. The last demographic census (IBGE, 2002) in Brazil indicated that 14.5% of the total population (24.5 million) present some type of impairment. This study aimed to evaluate the prevalence of dental trauma (DT) in individuals with special needs and the first attendance by a dental surgeon of patients admitted to the special care clinic of the School of Dentistry of Universidade Paulista (UNIP), Brazil, between 2001 and 2005. MATERIAL AND METHODS: The sample included 544 individuals with special needs aged 1-20 years old (mean 10.7 ± SD 5.3). Patient medical records were reviewed for demographic and clinical data, including medical diagnosis, gender, age, presence of DT and whether the attendance provided was the first time the patient had sought dental treatment. RESULTS: The individuals were distributed into 11 subgroups according to medical diagnosis. The DT prevalence determined was 9.2% (n = 50), with no difference in relation to gender. The majority (78.3%) of the individuals were seeking dental treatment for the first time at an advanced age. CONCLUSIONS: The present data suggest that DT prevalence in individuals presenting special needs is more common in permanent dentition and that the first attendance by a dental surgeon is delayed.

Caries experience in individuals with cerebral palsy in relation to oromotor dysfunction and dietary consistency.

The aim of this study was to investigate caries experience in individuals with cerebral palsy (CP) who have oromotor dysfunction and relate it to age and dietary consistency. Noninstitutionalized individuals with CP (n = 108) aged 4-19 years (mean: 10 years, 1 month +/- SD 4 years, 5 months) were recruited for this study. Subjects who were severely impaired (35.2%) had orofacial motor dysfunction most frequently, followed by those who were slightly affected (27.7%), moderately affected (20.4%), and very slightly affected (16.7%). Age was a statistically significant factor for oromotor dysfunction (p= 0.007), with the youngest individuals having the most severe oromotor problems. Dietary consistency and oromotor function were statistically significant influence on the DMF index (p= 0.0352). The highest total DMF values were measured for individuals who were severely impaired and also the youngest, as well as for those receiving liquid diets. Early rehabilitation, intervention, and prevention are important for these individuals.

Inflammatory markers in the saliva of cerebral palsy individuals with gingivitis after periodontal treatment.

The aim of this study was to evaluate the effect of periodontal treatment on the salivary cytokine levels and clinical parameters of individuals with cerebral palsy (CP) with gingivitis. A non-randomized, clinical trial was conducted in individuals diagnosed with spastic CP. Thirty-eight individuals were enrolled in the study and were categorized according to gingival index scores between 0-1 or 2-3, assigned to groups G2 or G1, respectively. Periodontal treatment comprised oral hygiene instructions, conventional mechanical treatment and 0.12% chlorhexidine applied as an adjunct. Clinical parameters and saliva samples were collected at baseline and at the 15-day follow-up visit. Bleeding on probing and periodontal screening and recording were determined. Non-stimulated saliva samples were obtained, and the salivary flow rate, the osmolality and the levels of cytokines IL-1ß, IL-6, IL-8, IL-10, TNF-α and IL-12p70 were evaluated by a cytometric bead array. The Wilcoxon test, the Mann-Whitney test, Spearman correlation analysis, Poisson regression analysis and an adjusted analysis were performed (α = 0.05). The groups differed significantly in periodontal clinical parameters at baseline and at follow-up. Salivary flow rate and osmolality were similar in both groups at both timepoints. However, TNF-α and IL-1ß levels were higher in G1 than in G2 at baseline. Mechanical treatment resulted in improved clinical parameters for both groups. Furthermore, mechanical treatment resulted in a significant reduction in salivary IL-1ß and IL-8 levels for both groups after treatment. Periodontal treatment performed in individuals with CP and gingivitis reduces the levels of TNF-α, IL-1ß, IL-6 and IL-8.

Communication Application for Use During the First Dental Visit for Children and Adolescents with Autism Spectrum Disorders.

PURPOSE: The purpose of this study was to develop and evaluate an application (app) facilitating patient-professional communication among individuals with autism spectrum disorder (ASD) and compare it with the Picture Exchange Communication System (PECS). METHODS: Forty nine- to 15-year-olds were randomly divided into two groups: G1 (app; N equals 20) and G2 (PECS; N equals 20). Initially, the visual contact timing of the groups was measured. Pictures of a room, ground, chair, dentist, mouth, low-speed handpiece, and air-water syringe were presented to both groups. Each picture was shown up to three times per appointment to evaluate whether or not the child accepted the procedure. After dental prophylaxis, caries experience was recorded. RESULTS: The prevalence of dental caries was 37.5 percent. Differences in the number of attempts required for each picture to acquire the skill proposed were found between the groups (Mann-Whitney, P<0.05). A significant difference in the median number of attempts (G1 equals 9.5 and G2 equals 15) and appointments (G1 equals three and G2 equals five) was observed (Mann-Whitney, P<0.05). CONCLUSIONS: The app was more effective than the Picture Exchange Communication System for dentist-patient communication, decreasing the number of appointments required for preventive dental care and clinical examinations.

Introdução: a Hipomineralização Molar Incisivo (HMI) é um defeito qualitativo de desenvolvimento de esmalte que pode ocasionar fraturas pós-eruptivas (FPE), lesões de cárie e sensibilidade. Objetivo: relatar o tratamento de HMI severa através da cimentação de bandas ortodônticas para preservação da estrutura dentária em primeiros molares permanentes inferiores com FPE. Relato do caso: criança do sexo feminino, 10 anos de idade, apresentou-se com queixa de hipersensibilidade e fratura dentária associada à restauração prévia. Clinicamente, observou-se presença de HMI severa, com FPE associada à lesão de cárie em dentina nas superfícies oclusal e vestibular do dente 36 e restauração insatisfatória com cimento de ionômero de vidro (CIV) na superfície vestibular do dente 46 que apresentava opacidades demarcadas branco-creme. Radiograficamente, observou-se ausência de comprometimento pulpar. Após manejo por meio de abordagens não-invasivas (controle de biofilme e dieta e aplicação de verniz fluoretado), o tratamento proposto foi a cimentação de banda ortodôntica com CIV modificado por resina (Riva Light Cure®, SDI) nos dentes 36 e 46 para maior longevidade das restaurações. O tratamento restaurador atraumático (TRA) foi realizado no dente 36 previamente à cimentação da banda ortodôntica. Resultados: após o tratamento, a criança não relatou dor ou desconforto e as restaurações mantiveram-se intactas. A mãe da criança foi orientada quanto à importância de acompanhamento periódico a cada 4 meses. Conclusão: a cimentação das bandas ortodônticas com CIV possibilitou o manejo conservador de molares permanentes com HMI severa, com manutenção de sua funcionalidade oclusal, saúde pulpar e gengival, proporcionando melhor qualidade de vida à paciente.

Introduction: molar Incisor Hypomineralization (MIH) is a qualitative developmental enamel defect that can cause posteruptive enamel breakdown (PEB), caries lesions, and sensitivity. Objective: to report the treatment of a child with severe MIH through the cementation of orthodontic bands in lower first permanent molars with PEB to preserve tooth structure. Case report: female child, 10 years old, presenting hypersensitivity complaints and tooth fracture associated with previous restoration. Severe MIH was observed, with PEB associated with dentin caries on the occlusal and buccal surfaces of tooth #36 and unsatisfactory glass ionomer cement (GIC) restoration on the buccal surface of tooth #46 which had creamy-white marked opacities. There was no pulp involvement radiographically. After management through non-invasive approaches (biofilm and diet control and application of fluoride varnish), the proposed treatment was the cementation of an orthodontic band with resin-modified GIC (Riva Light Cure®, SDI) on teeth #36 and #46 to long-term lifespan restorations. Atraumatic restorative treatment (ART) was performed on tooth #36 prior to the cementation of the orthodontic band. Results: after treatment, the child did not report pain or discomfort and the restorations remained intact. The child's mother was instructed about the importance of periodic follow-up visits every 4 months. Conclusion: the cementation of orthodontic bands with GIC allowed the conservative management of permanent molars with severe MIH, maintaining their functional occlusion, pulpal and gingival health, providing a better quality of life to the patient.

Correlation of salivary immunoglobulin A with Body Mass Index and fat percentage in overweight/obese children.

Obesity is considered a risk factor for periodontal health due to the low- grade inflammation promoted by the increased adipose tissue. OBJECTIVE: This study aimed to determine correlations and associations between gingival inflammation (Simplified Oral Hygiene Index, and Gingival Index), salivary immunoglobulin A (s-IgA), and salivary parameters (salivary flow and osmolality) in normal-weight and overweight/obese children. MATERIAL AND METHODS: Ninety-one children, aged 6 to 12 years old (8.6±1.9 years), were divided into two groups according to their body mass index (BMI), circumferences, skinfold measurements and body fat percentage: normal- weight group (NWG; n =50) and overweight/obese group (OG; n =41). A calibrated examiner performed the clinical examination using the Simplified Oral Hygiene Index, Gingival Index, and salivary collection. Data analysis included descriptive statistics and association tests ( p <0.05). RESULTS: OG presented statistically higher s-IgA values compared with NWG, especially among the obese children ( p <0.05). Significant positive correlations between s-IgA and salivary osmolality in OG ( p <0.05), and between s-IgA and BMI values ( p <0.05) and body fat percentage ( p <0.05) were observed among all the children. Effect size varied from moderate for s-IgA values ( d =0.57) to large for BMI ( d =2.60). CONCLUSION: Gingival inflammation and salivary parameters were similar for NWG and OG; however, s-IgA presented higher values in OG, with correlations between BMI and body fat percentage.

Association of salivary parameters and erosive tooth wear in preschool children

Abstract The aims of this study were to 1) assess the association between erosive tooth wear (ETW) according to the BEWE (Basic Erosive Wear Examination) scoring system and salivary parameters and 2) compare salivary parameters according to ETW severity in the subgroup of children with ETW. This cross-sectional study included 52 preschool children aged 5 years paired by sex. A calibrated examiner assessed ETW using BEWE criteria, and stimulated saliva was collected to determine salivary flow, osmolality, pH, and buffering capacity. The children were divided into two groups: without ETW (n=26; BEWE score 0) and with ETW (n=26; BEWE scores 1 and 2). Logistic regression analysis was used to determine the magnitude of the association between ETW and salivary parameters and estimates of odds ratios (OR). In the unadjusted analysis, the ETW group was more likely to have lower salivary flow (OR = 0.079; 95%CI = 0.013-0.469; p = 0.005) and lower osmolality (OR = 0.993; 95%CI = 0.985-1.000; p = 0.049). In the adjusted analysis, salivary flow remained significantly associated with ETW (OR = 0.087; 95%CI = 0.014-0.533; p = 0.008). Lower salivary osmolality values were observed in ETW, especially in preschool children with more severe ETW (BEWE score 2). Receiver operating characteristic (ROC) determined a salivary osmolality cutoff point of < 201 for the presence of ETW. In conclusion, salivary flow rate was significantly associated with ETW prevalence. Lower values of salivary osmolality were observed in preschool children with distinct erosive lesions with significant loss of tooth structure (BEWE 2).

Shprintzen-goldberg craniosynostosis: craniofacial and oral characteristics, diagnosis, and clinical management of a very rare syndrome / Craniossinostose de shprintzen-goldberg: características craniofaciais e orais, diagnóstico e manejo clínico de uma síndrome muito rara

ABSTRACT Shprintzen-Goldberg craniosynostosis syndrome, characterized by craniosynostosis and marfanoid habitus, is a very rare entity described in 75 individuals worldwide. This study aimed to present a case report of a 6-year-old female Brazilian child with Shprintzen-Goldberg's craniosynostosis syndrome. We described the craniofacial and oral characteristics and its clinical management, comparing to the existing literature. The patient presented with intellectual disability, craniosynostosis, ocular proptosis, low-set anomalous ears, and other skeletal and connective tissue defects. Oral features included malocclusion, micrognathia, pseudo-cleft palate, dental caries, and inefficient biofilm control. The treatment started with guidance on cariogenic foods, oral hygiene, and an indication to discontinue bottle feeding. Subsequently, the carious lesions were restored with composite resins, and the patient was referred for orthopedic surgery, orthodontic treatment, speech therapy, and nutritional counseling. The patient was followed for 5 years. This case report emphasizes the importance of knowing the craniofacial and oral characteristics for the diagnosis and clinical management of a female child with a rare Shprintzen-Goldberg's craniosynostosis syndrome. The case also highlights the need for oral health care in individuals with intellectual disabilities.

Use of a Picture Exchange Communication System for preventive procedures in individuals with autism spectrum disorder: pilot study.

The aim of the present study was to evaluate the use of the Picture Exchange Communication System (PECS) in individuals with autism spectrum disorder (ASD) in order to facilitate patient-professional communication during preventive procedures. In this study, 26 patients with ASD, between 5 and 19 years of age (10±3.3 y), were divided into two groups: G1 (n = 13) with no previous experience of dental treatment, and G2 (n = 13), with such previous experience. The initial approach followed the principles of the Son-Rise Program®. The seven PECSs presented the routine of the dental office: "room," "ground," "chair," "dentist," "mouth," "low," and "triple." Each PEC was used up to three times in order to acquire the skill proposed. It was verified that G2 required a greater number of times to achieve the acceptance of PECS "ground," "dentist," "mouth," and "triple" (p < .05). We concluded that PECS facilitated patient-professional communication during preventive procedures, including for ASD patients with previous dental experience.

Association Between Visual Inspection, Caries Activity Status, and Radiography with Treatment Decisions on Approximal Caries in Primary Molars.

PURPOSE: The purpose of this study was to evaluate the in vivo performance of the International Caries Detection and Assessment System (ICDAS), Lesion Activity Assessment (LAA), and bitewing radiographs (BW) in detecting carious lesions on approximal surfaces of primary teeth and determine their association with treatment decisions (TDs). METHODS: Eighty-nine primary molars (166 approximal surfaces) in 56 eight- to 12-year-old children were clinically evaluated by a single examiner before and after temporary tooth separation. After exfoliation/ extraction, the teeth were histologically analyzed for caries depth and activity. RESULTS: Sensitivities for ICDAS and ICDAS-LAA were higher after tooth separation, while specificities were lower (P<0.05). The sensitivity and specificity values for BW were 0.49 and 0.79, respectively. The strongest correlations were found between ICDAS and BW before and after tooth separation, and between ICDAS and ICDAS-LAA and ICDAS and TDs before tooth separation (P<0.05). CONCLUSIONS: The International Caries Detection and Assessment System assessment after tooth separation presented better clinical performance than bitewing radiography for the detection of approximal carious lesions in primary molars. There was a high correlation between treatment decisions based on ICDAS, ICDAS-Lesion Activity Assessment, and bitewing radiography, highlighting the functional similarity of these tools in the clinical decision-making process.

Different bacterial models for in vitro induction of non-cavitated enamel caries-like lesions: Microhardness and polarized light miscroscopy analyses.

The aim of this study was to compare different bacterial models for in vitro induction of non-cavitated enamel caries-like lesions by microhardness and polarized light microscopy analyses. One hundred blocks of bovine enamel were randomly divided into four groups (n = 25) according to the bacterial model for caries induction: (A) Streptococcus mutans, (B) S. mutans and Lactobacillus acidophilus, (C) S. mutans and L. casei, and (D) S. mutans, L. acidophilus, and L. casei. Within each group, the blocks were randomly divided into five subgroups according to the duration of the period of caries induction (4-20 days). The enamel blocks were immersed in cariogenic solution containing the microorganisms, which was changed every 48 h. Groups C and D presented lower surface hardness values (SMH) and higher area of hardness loss (ΔS) after the cariogenic challenge than groups A and B (P < 0.05). As regards lesion depth, under polarized light microscopy, group A presented significantly lower values, and groups C and D the highest values. Group B showed a higher value than group A (P < 0.05). Groups A and B exhibited subsurface caries lesions after all treatment durations, while groups C and D presented erosion-type lesions with surface softening. The model using S. mutans, whether or not it was associated with L. acidophilus, was less aggressive and may be used for the induction of non-cavitated enamel caries-like lesions. The optimal period for inducing caries-like lesions was 8 days.
