Risk factors for recurrence of periodontal disease in patients in maintenance care in a private practice.

J Clin Periodontol. 2019 Jul 4. doi: 10.1111/jcpe.13165.



To assess periodontal and dental conditions in individuals in maintenance care after periodontal therapy in private practice, and identify risk factors for recurrence of disease and tooth loss.


100 patients attending a routine recall visit were included. All had been treated for periodontal disease and were in maintenance since ≥2 years.


Examinations took place 18.0 (±8.71) years after the start of periodontal therapy. 40.1±22.5 recall visits were registered during this time. 91% of the participants had an initial diagnosis of chronic, 9% of aggressive periodontitis. The average participant was 46 years old and had 26 teeth. 283 of 2549 initially present teeth were lost, half of them being molars. Periodontal and endo-periodontal complications accounted for only 16 lost teeth. The prevalence of all probing depth (PD) categories decreased significantly. The longer the time, the more frequent the recall visits, and the more was spent during the maintenance phase the greater was the reduction. Multivariate analysis rendered BMI and smoking as factors influencing number of sites with PPD ≥4 mm and BOP.


Tooth loss and periodontal tissue damage can be contained over prolonged periods if periodontal disease is treated and patients attend regular maintenance care.

Are You Curing Your Dental Materials? checkUp Lets You Know.

Are you curing your composites?
Curing composites does not mean turning on the curing light and assuming since the top layer is hard everything has been done properly.  There are many importation aspects to properly curing all of the materials that we use in our daily workflows. Since about half of our procedures require a curing light. From bonding agents, composites and core materials all of these require proper cure times based on the power output of the lights along with excellent technique.  Incomplete curing causes a host of problems for both the patient and dentist.

There is a new product on the market that is more then just a radiometer and its from a company called Blue Light Analytics.  They have a device called checkUp. Using Bluetooth the device connects to an app on your smartphone. It looks like a small hockey puck and not only measures the power output of your curing light but uses artificial intelligence to query its database of materials to guide you on the proper curing times for all your materials.

Here are some screenshots of my recent use of checkUP. One of the interesting things I have found out is my brand name barriers actually reduce my output by approximately 100mw/cm2.

For a limited time you can purchase the checkUp device and service by clicking here for the July special of 50% off

Comprehensive assessment of dental behaviour and oral status in patients with tongue piercing—results of a cross-sectional study

First Online:



Aim of this cross-sectional case-control study was the comprehensive examination of oral health, oral behaviour and oral health-related quality of life of patients with tongue piercing. Furthermore, different piercing related factors and the presence of habits should be considered regarding their potential association to piercing-related complications.

Material and methods

Participants with tongue piercing (n = 50) and a matched control (n = 50) were included. Dental examination included decayed-, missing- and filled-teeth-index (DMF-T) and the presence of non-carious tooth defects. Periodontal examination contained of periodontal probing depth (PPD), bleeding on probing (BOP) and recession. Piercing-related factors, oral behaviour as well as oral health-related quality of life [German short form of oral health impact profile (OHIP G14)] were assessed based on questionnaires. Statistics: Man-Whitney U test, chi-square and Fisher’s exact test (significance level p < 0.05).


Participants with tongue piercing suffered from worse DMF-T, PPD, BOP and recession (pi < 0.01). Higher prevalence of enamel cracks and trough-shaped abrasions were found in piercing-group (pi < 0.01). Additionally, participants with tongue piercing showed worse oral behaviour, insufficient cleaning of piercing and in majority of cases (80%) calculus formation at piercing surface as well as comparable OHIP-G14 to control (p = 0.39). While piercing design was associated to both, recession and non-carious tooth defects (pi < 0.05), only infractures of enamel were associated to the presence habits (p = 0.04).


Patients with tongue piercing show insufficient dental and periodontal health as well as reduced oral behaviour. Thereby, piercing design and wearing period is associated to recessions and non-carious tooth defects.

Clinical relevance

Increased attention of patients wearing tongue piercing in dental practice is necessary.

Case Report Mandibular incisor extraction: A treatment alternative for large maxillary midline diastema

International OrthodonticsInternational Orthodontics

Available online 3 July 2019


Maxillary midline diastema is a common aesthetic concern of dental patients. Various treatment modalities have been employed to close diastemas. This case report describes an unusual orthodontic treatment approach for a 25-year-old African American female patient with a large maxillary midline diastema of 5 mm, bialveolar dental protrusion and unilateral Class III malocclusion. The treatment included one mandibular incisor extraction, followed by retraction of the incisors. At the end of the 16-month active treatment period, favourable aesthetic and occlusal outcomes were attained. Closure of midline diastema, good overjet and overbite with Class I molar relationships were achieved.

Clinical significance

Fixed orthodontic treatment with single mandibular incisor extraction can be an effective treatment choice for a large maxillary midline diastema. With careful selection of the case and treatment planning, successful results can be obtained.

Nd:YAG laser and calcium sodium phosphosilicate prophylaxis paste in the treatment of dentin hypersensitivity: a double-blind randomized clinical study

This double-blind, placebo-controlled, randomized clinical trial evaluated the effectiveness of Nd:YAG laser and a calcium sodium phosphosilicate–containing paste (NovaMin®) in the treatment of cervical dentin hypersensitivity (CDH).

Materials and methods

Seventy patients were randomly allocated into the following experimental groups: control-placebo, calcium sodium phosphosilicate paste (NovaMin®), and Nd:YAG laser (1 W, 10 Hz, 85 J/cm2). Pain was evaluated by means of a visual analog pain scale (VAS) after evaporative stimulation with a jet of air and tactile stimulation with an exploratory probe, before treatment (baseline) and after 5 min, 1week, and 4 weeks. When patients presented more than one tooth with CDH, the mean of the values obtained was calculated. Irradiation with Nd:YAG laser was performed twice in the mesial-distal and twice in the occlusal-gingival direction. The NovaMin®-containing paste was applied with a rubber cup at low speed for 60 s. Patients of the placebo group received simulations of the two treatments. As the data presented normal distribution, the two-way ANOVA repeated measures test was used.


In all the experimental times, reduction in pain was demonstrated in comparison with baseline for all treatments (p < 0.05); however, there was no difference among the experimental groups in any of the time intervals evaluated (p > 0.05).


All treatments were equally effective in reducing the pain of CDH.

Clinical relevance

Nd:YAG laser irradiation and the calcium sodium phosphosilicate paste could reduce the symptoms of CDH; thus, they stand out as viable alternatives for the treatment of this condition.
