This randomized, multicenter clinical trial evaluated the effectiveness of 2 treatments for deep caries lesions - partial caries removal (PCR) and stepwise excavation (SW) - with respect to the primary outcome of pulp vitality for a 3-year follow-up period. Inclusion criteria were as follows: patients with permanent molars presenting deep caries lesions (lesion affecting ≥ 1/2 of the dentin on radiographic examination), positive response to a cold test, absence of spontaneous pain, negative sensitivity to percussion, and absence of periapical lesions (radiographic examination). Teeth randomly assigned to PCR (test) received incomplete caries removal and filling in a single session. Outcome success was evaluated by assessment of pulp vitality, determined by pulp sensitivity to a cold test and the absence of periapical lesions. Data were analyzed by a Weibull regression model with shared frailty term (survival analysis). At baseline, 299 treatments were executed: PCR, 152 and SW, 147. By the end of the 3-year follow-up period, 213 teeth had been evaluated. Adjusted survival rates were 91% for PCR and 69% for SW (p = 0.004). These results suggest that there is no need to re-open a cavity and perform a second excavation for pulp vitality to be preserved (Clinical trials registration NCT00887952).
This study supports the PCR as a single-visit technique to manage deep caries lesions in permanent teeth.
Aim: The aim of this study was to evaluate the effectiveness of partial removal of carious dentine and restoration in a single session (PDR) and stepwise excavation (SW), both of which are treatments for deep carious lesions, in Public Health Services in Brazil. Methods: Inclusion criteria: patients ≥6 years old, permanent molars with deep caries lesions (having a radiolucency halfway or more into dentine) and pulp vitality but absence of spontaneous pain, positive percussion test, and periapical alterations. The subjects received either PDR (test group) or SW (control group). The radiological and clinical exams were performed after a mean time of 18 months. Outcomes: success was defined as pulp sensitivity to cold test and absence of periapical alterations. Results: Of the 299 treatments performed, 146 were SW and 153 were PDR; 122 were amalgam restorations and 168 resin-composite restorations. There were no differences between the groups regarding the baseline characteristics (i.e. age, gender and family income). After 18 months, 212 evaluations were performed, which indicated 99 and 86% success rates in the PDR and SW groups, respectively (p = 0.016). Reasons for failure were: PDR – 1 pulpitis; SW – 8 pulpitis; 1 osteitis; 4 necrosis; 1 endodontic treatment. None of the baseline variables were significantly associated with the outcomes. Conclusion: The retention of carious dentine does not interfere in pulp vitality. Data from this 18-month study suggest that the procedure of reopening the cavity to remove the residual infected dentine is not necessary.
This study assessed the extent to which clinically measured oral health conditions, adjusted for sociodemographic and oral health behavior determinants, impact adversely on the oral health-related quality of life (OHRQoL) in a sample of Belgian young adults. The null hypothesis was that, among young adults, the oral health conditions would have no impact on their quality of life. The participants were 611 new patients aged 16-32 years seeking consultation at the Saint-Luc University Hospital in Brussels in 2010-2011. The patients (56.0% female) were examined for their oral health conditions and answered a validated questionnaire about sociodemographic and oral health behavior determinants in addition to questions about their OHRQoL. The abridged Oral Health Impact Profile-14 was used to assess the OHRQoL. Interexaminer reliability for caries was 0.86 (95% CI 0.84-0.89, nonweighted κ). The outcome was a high score on the OHRQoL (median split). Hierarchical logistic regression analysis showed that young adults with clinical absolute D1MFS scores between 9 and 16 (OR = 2.14, p = 0.031) and between 17 and 24 (OR = 3.10, p = 0.003) were significantly more likely to report a high impact on their quality of life than those with lower scores. Also, periodontal conditions compromised significantly (OR = 1.79, p = 0.011) the quality of life of young adults. In conclusion, this study identified oral health conditions with a significant adverse effect on the OHRQoL of young adults. However, the prevalence of young adults reporting impacts on at least 1 performance affected fairly often or very often was limited to 18.7% of the sample.
This paper explores some of the most relevant questions faced by dental practitioners when diagnosing early erosive tooth wear (ETW) and implementing non-operative management of this condition over time. It focuses on the identification of clinical signs and common locations of ETW lesions, the assessment of individual risk and the implementation of non-operative management strategies, aiming to arrest and/or reduce the rate of ETW progression and avoid its advance to pathological stages. To this end, we present a novel and comprehensive approach that considers the whole dentition of patients rather than individual groups of teeth or dental surfaces only, illustrating it with a series of clinical photographs. Dental practitioners may find this approach particularly helpful as it closely simulates the clinical examinations of patients of all age groups carried out in daily practice. The clinical signs of early ETW lesions are subtle and often not perceived as relevant by unaware clinicians. However, the early diagnosis and implementation of non-operative management strategies, especially at younger ages, is fundamental for the proper control of ETW over time.
