    Manpreet Kaur, Rajinder Kumar Sharma, Shikha Tewari, Satish Chander Narula

    IntroductionDryness is known to be associated with inflammatory diseases such as dry eye disease and atopic dermatitis. There is significant water loss from the oral cavity during mouth breathing. This study is conducted to estimate the influence of mouth breathing on the outcome of scaling and root planing (SRP) in chronic periodontitis (CP).Materials and methodsCP patients comprising of 33 mouth breathers (MBs) and 33 nose breathers (NBs) were recruited. Thirty patients in each group completed the study. At baseline, plaque index (PI), gingival index (GI), bleeding on probing (BOP), probing depth (PD), and clinical attachment level (CAL) were measured. SRP was done in both groups. At the 4th, 8th, and 12th week, PI, GI, and BOP were recorded. PD and CAL were also assessed at the 12th week.ResultsAt the 12th week, there was significantly less improvement in GI at palatal sites of maxillary anterior and maxillary posterior teeth in MB group. Sixty-nine percent of BOP positive sites with PD >4 mm were converted into BOP negative sites with PD ≤4 mm in maxillary posterior palatal sites in NB. This success was 38% in MB.ConclusionControl of periodontal inflammation by SRP in CP patients is affected at palatal sites of mouth breathers.

  • Experience with bruxism in the everyday oral implantology practice in the Netherlands: a qualitative study
    BDJ Open Pub Date : 2018-11-09
    Magdalini Thymi, Annemiek Rollman, Corine M. Visscher, Daniel Wismeijer, Frank Lobbezoo

    ObjectiveTo explore how bruxism is dealt with by accredited oral implantologists within daily clinical practice.Materials and methodsNine semi-structured interviews of oral implantologists practicing in non-academic clinical practices in the Netherlands were performed, and thematic analysis was conducted using a framework-based approach.ResultsOral implant treatments in bruxing patients were a generally well-accepted practice. Complications were often expected, with most being of minor impact. Contradictive attitudes emerged on the topic of bruxism being an etiologic factor for peri-implant bone loss and loss of osseointegration. Views on the ideal treatment plan varied, though the importance of the superstructure’s occlusion and articulation features was repeatedly pointed at. Similarly, views on protective splints varied, regarding their necessity and material choice. Bruxism was diagnosed mainly by clinical examination, alongside with patient anamnesis and clinician’s intuition. There was little attention for awake bruxism.DiscussionBruxism was generally not considered a contraindication for implantological treatments by accredited oral implantologists. Views on the interaction between bruxism and bone loss/loss of osseointegration varied, as did views on the ideal treatment plan.ConclusionsThere is a need for better understanding of the extent to which, and under which circumstances, sleep and/or awake bruxism can be seen as causal factors for the occurrence of oral implant complications.

  • The antibacterial efficacy of a foam mouthwash and its ability to remove biofilms
    BDJ Open Pub Date : 2018-09-27

    Objectives/Aims To evaluate the antimicrobial activity of a newly developed foam mouthwash containing a modified lactoperoxidase system in vitro. Materials and methods Biofilms of five bacterial species were developed on hydrophobic and hydrophilic surfaces whilst salivary-based biofilm was grown on tooth enamel. Each surface was exposed to the foam mouthwash or saline in vitro. Optical density and scanning electron microscopy (SEM) was used to determine retention of the biofilm following 5 or 30 s exposure time. Results The foam mouthwash was active against biofilms formed by S. aureus, K. rhizophila, M. thailandicus, E. coli, and C. violaceum and eliminated significant amount of biofilm from each surface; immature 4 h biofilm was less resistant than 24 h biofilm. A 30 s rinse showed best performance, with removal of up to 66% of biofilm from the hydrophilic surface. SEM imaging confirmed oral biofilm removal from the enamel surface after a 5 s rinse with the foam mouthwash. Discussion Foam mouthwash demonstrated a significant impact on growing biofilm when compared against saline solution. Growing biofilms were more susceptible to the action of the foam mouthwash, which justifies after-meal use of the mouthwash when traditional dentifrices may not be accessible. Conclusions Foam mouthwash can be a convenient on-the-go format of oral care products that can be used after meals or when needed to reduce the risk of biofilm-associated oral conditions.

  • Oral health-related quality of life in patients with upper gastrointestinal and hepatic disorders in Pakistan: validation of the Oral Health Impact Profile-14 in the Urdu language
    BDJ Open Pub Date : 2018-04-27

    IntroductionThe Oral Health Impact Profile (OHIP-14) has been used extensively to measure the impact of oral disease on oral health-related quality of life (HRQoL) but has not been validated in the Urdu language or tested in gastroenterology.AimsTo validate the OHIP-14 for use in Pakistan and its ability to assess oral health in patients with upper gastrointestinal (GI) and hepatic disorders.DesignMulticentre, cross-sectional.SettingFour major tertiary care hospitals.MethodsThe OHIP-14 was tested for reliability and validity in 700 patients referred for oesophago-gastro-duodenoscopic (OGD) investigation of the symptoms of upper GI or hepatic disease. Socio-demographic details and oral examination findings (for oral lesions and DMFT) were recorded.ResultsThe mean (±standard deviation) total OHIP-14 score (range 0–56) was estimated to be 23.38 ± 10.47, indicating a significant impact of upper gastrointestinal and hepatic disorders on oral health. The reliability coefficient of the OHIP-14 was above 0.7 threshold, and the tool had good internal consistency (α = 0.83). When associated with worsening DMFT (decayed, missed, and filled teeth) index value, the highest correlations (p < 0.01) were detected with functional limitation (rs = 0.234), physical disability (rs = 0.230), and psychological discomfort (rs = 0.221).ConclusionThe OHIP-14 is a precise and valid instrument for assessing oral-HRQoL in a gastroenterological setting amongst Pakistani population.

  • Effectiveness of prosthodontic interventions and survival of remaining teeth in adult patients with shortened dental arches—Protocol for a systematic review and meta-analysis
    BDJ Open Pub Date : 2018-04-27

    To evaluate studies of the effectiveness of different tooth replacement strategies in adult patients with shortened dental arches (SDA). Specifically, the objectives of the proposed review are to determine the survival rates of different prosthodontic interventions; the risk of tooth loss with and without different prosthodontic interventions; and the impact of different tooth replacement strategies on oral-health related quality of life (OHRQoL).

  • Remediation of adult black dental stains by phototherapy

    Introduction and aimsThis study investigates the effects of the application of antimicrobial phototherapy on black-stained tooth surfaces. Key variables were area, color and time taken to reappearance of black stain following dental prophylaxis with and without antimicrobial phototherapy. Differences in bacterial composition of black stain (specifically Aggregatibacter actinomycetemcomitans, Tannerella forsythia, and Porphyromonas gingivalis) were analyzed.Material and methodsThe phototherapy device used was GLO™ Science LLC, New York, America, emitting light at 475 nm and a power of 3 W. Light was applied in 2 cycles of 8 min on 31 volunteers. Microbial identification was carried out on DNA extracted from black plaque. This study is registered with ClinicalTrials.gov, number NCT03309748.ResultsFollowing antimicrobial phototherapy, 64.5% of patients displayed reduced pigmentation area. Plaque color was lighter in 48.4% of subjects. Pigmentation area and depth of color returned to normal levels during the course of the study. Colonization by the three bacterial species decreased, although the changes were not statistically significant. We report a key novel finding showing elevated levels of colonization by Tannerella forsythia (83.9%) in adult black stain.ConclusionsApplication of phototherapy results in a reduction in area, color and bacterial colonization of black plaque in adults. The changes were not found to be statistically significant, perhaps owing to the low illumination power of the home-whitening device. For the first time, we document the elevated presence of Tannerella forsythia in adult black stain. We also demonstrate the potential application of a commercially available home-whitening device for black plaque treatment.
