This study aimed to evaluate the orthodontic effect and efficiency of substituting third molars for missing first or second permanent molars systematically....
Forty-six patients (69 third molars total) with missing permanent molars replaced by third molars were selected. The angulation, crown-to-root ratio, and periodontal condition of the third molars befo...
The average orthodontic treatment time was 33.9 ± 5.6 months, and the average angulation change of third molars during treatment was 49.8 ± 29.8°. The average height of mesial alveolar bone increased ...
If the indications and timing of treatment were well-controlled, third molars would be excellent substitutes for missing first or second permanent molars through the orthodontic method....
Molar incisor malformation (MIM) is a dental anomaly rendering first permanent molar pulps inflamed/necrotic at a young age. It often affects permanent incisors, primary second molars and less frequen...
Five MIM first permanent molars were examined with micro-computed tomography (micro-CT) for 3D morphology, with scanning electron microscopy for microanatomy, with energy-dispersive X-ray spectrometer...
Micro-CT confirmed dentin abnormalities in the middle and cervical third of the crown in the form of the radiodense 'cervical mineralized diaphragm' (CMD). This was peripherally intertwined with ename...
An interconnection of anomalous cervical enamel with crown CMD dentin preceded to the severe pulp chamber and root dysplasias in MIM molar teeth....
This paper provides an insight into the historical recommendations regarding removal of mandibular third molars, as set out by the Royal College of Surgeons of England and the National Institutes of H...
This prospective study was designed to determine the prognosis of second molars with external root resorption (ERR-M2s) caused by embedded third molars (EM3s) following EM3 removal and explore related...
This study consecutively enrolled 58 participants who had asymptomatic second molars with apical external root resorption caused by EM3s. EM3s were extracted, and follow-up examinations were conducted...
A total of 63 ERR-M2s from 58 patients (16 males and 42 females; 19-57 years of age) were evaluated. At the last follow-up, 56 teeth (89%) remained asymptomatic and normal response to heat and cold te...
Asymptomatic ERR-M2s have a high probability of remaining normal pulp without further intervention after EM3 extraction, especially in younger patients. No intervention except follow-up and observatio...
Molar incisor hypomineralisation (MIH) and hypomineralised second primary molars (HSPMs) are commonly seen dental developmental problems with a mean prevalence of around 14% and 9%, respectively, but ...
This study evaluated the occlusal status of the maxillary third molars that erupted spontaneously after extraction of the maxillary second molars and investigated the factors that influenced the occlu...
We assessed 136 maxillary third molars in 87 patients. Alignment, marginal ridge discrepancy, occlusal contact, interproximal contact, and buccal overjet were used to score the occlusal status. Occlus...
G, A, and P groups comprised 47.8%, 17.6,% and 34.6% of the sample, respectively. Age was the lowest in the G group at both T0 and T1. The maxillary tuberosity space at T1 and the amount of the change...
Good-to-acceptable occlusion was seen in 65.4% of the maxillary third molars after maxillary second molar extraction. Insufficient increase in the maxillary tuberosity space and Nolla stage 8 or highe...
To assess whether the prevalence of dental caries is associated with the presence of molar-incisor hypomineralisation (MIH) in first permanent molars (FPMs)....
A cross-sectional study was conducted with a sample of 5368 FPMs from 1342 children aged 8-10 years from Florianopolis, Brazil. Dental caries was evaluated with the Decayed, Missing and Filled Teeth (...
The presence of MIH was associated with a 6.15 times higher prevalence of dental caries in FPMs (PR: 6.15; 95%CI: 4.18-9.04). A monthly family income ≤2 minimum wages and the caries experience in the ...
The presence of MIH showed a significant association with the prevalence of dental caries in FPMs. Thus, dentists should be alert to cases of MIH. Once the condition is detected, preventive measures s...
Whether there is a relationship between impaction of the third molars and the onset of crowding remains to be determined, and extraction of third molars after orthodontic treatment is left to the judg...
The aim of this systematic review and meta-analysis is to identify the risk factors of external root resorption (ERR) on second molar (M2) due to presence of impacted third (M3) molar based on cone- b...
Search of PubMed...
M2 in close proximity to mesio-angular impacted M3 had 50% higher risk of root resorption than with vertical impacted M3 (RR 0.50 95% CI [0.35, 0.73],...
ERR in M2 was significantly affected by the contact with impacted M3 and most importantly, the inclination of M3. The presence of mesio-angular, horizontal or transverse impacted M3 in close proximity...
Studies were selected, using appropriate key words, from the following databases: Cochrane Central Register of Controlled Trials; Medline (via Pubmed); Scopus/Elsevier; and Embase. A manual search was...
Inclusion criteria included prospective studies and randomised controlled trials published in English, with a minimum 6-month follow-up reporting on parameters of periodontal healing distal to the man...
The 17 studies meeting the inclusion criteria underwent validity assessment and data extraction, including risk of bias analysis. Meta-analysis was performed to calculate mean difference and standard ...
The periodontal parameters investigated yielded the following results after meta-analysis: overall PPD reduction of 1.06 mm at 6 months and 1.67 mm at 12 months; final PPD of 3.81 mm at 6 months; CAL ...
Although M3M removal results in modest improvement in periodontal health distally of the second mandibular molar, periodontal defects remain onwards of 6 months. There is limited evidence suggesting a...
