The Effect of the Bass Intrasulcular Toothbrushing Technique on the Reduction of Gingival Inflammation: A Randomized Clinical Trial.

OBJECTIVES: The primary objective of this randomized controlled clinical trial was to investigate the effect of the Bass Intrasulcular Technique (BIT) on reducing gingival inflammation at 4 and 12 weeks compared with the toothbrushing techniques commonly used. METHODS AND MATERIALS: After receiving ethical approval from the Tufts Health Sciences Institutional Review Board, 55 subjects were invited to participate in the study. Only the subjects who presented with bleeding on probing (BoP) were enrolled. The test group (BT) was instructed on how to use the BIT, and the control group (NI) received no brushing technique instructions. Clinical measurements (probing depth, plaque score, BoP) of each tooth were recorded at 4 and 12 weeks. The toothbrushes of all participants were photographed and assessed by two blinded examiners using the ImageJ software. The statistical significance between the cohorts' BoP and their plaque score results was assessed via hierarchical logistic regression. The analyses were performed using the SAS software (version 9.4; SAS Institute, Cary, NC). RESULTS: Forty-eight participants were eligible to participate and were randomly assigned to one of the two groups (N = 24). The BT group showed significantly smaller percentages of BoP than the NI group at 4 (BT = 12.4% and NI = 31.4%) and 12 (BT = 11.6% and NI = 43.8%) weeks. The difference in plaque scores at 12 weeks was statistically significant (P = .0003) between the two groups. At 12 weeks, the Mann-Whitney U Test indicated that the difference between the groups in terms of toothbrush area was statistically significant (P = .043). CONCLUSIONS: Within the limitations of this randomized controlled clinical trial, the BIT used by participants in the BT group was significantly more effective in reducing gingival inflammation as determined by BoP than the techniques used by participants who had no instructions on brushing techniques; at 12 weeks, the BT group experienced less toothbrush deformation than the control group. CLINICAL RELEVANCE: BIT should be recommended particularly to patients exhibiting BoP and periodontal diseases.

Eye Safety in Dentistry and Associated Liability.

The first objective of this article is to expressan experimental-work-supported opinion ofits authors regarding the inadequacy of thepresent dental mask and regular eyewearcombination for protecting dental care practitioners. Its second objective is to suggestamending OSHA Standard 1910.133(a)(1) tomandate effective eye protection for dentalcare practitioners by requiring the use ofeffective means for closing the bottom gapsbetween the lower rims of the lenses of theprotective eyewear and the upper edge ofthe mask worn by the practitioner.The various types and sources of dentalpractice eye occupational hazards and thepossible entry routes of dental debris towarddental practitioners'eyes are discussed.Experimental work, confirming theinadequacy of the present dental mask andeyewear combination for protecting dentalcare practitioners, is presented.

An analysis of patient grievances in a dental school clinical environment.

Patient satisfaction is an integral part of assessing the quality of oral health care. As dental care becomes more impersonal, competitive, and expensive, the potential for patient complaints is on the rise. Dental school clinics may be more vulnerable to patient grievances due to inexperienced student providers, less efficient delivery of care, challenges related to continuity of care, and the complexity of adhering to institutional policies. Effective management of patient complaints can assist both individuals and institutions toward providing the highest quality of care achievable in the demanding dental education environment. Despite the obvious benefit, there is a dearth of recent studies that analyzed complaints in either the private practice setting or dental school clinics. The purpose of this study was to categorize and analyze the complaints received from patients seeking treatment at a large dental school clinic from 2005 to 2008. It was found that the combined complaints for all four years in descending order were regarding appointment, communication, money, quality, and other. No statistically significant association was found between the type of complaint and time of year. Most importantly, it was found that the system for recording complaints needed to be standardized in order to improve the quality of patient care. The findings from this study will not only facilitate adjustment of the school's current curricula and policies, but could also guide other institutions and private dental practitioners toward better patient care.

Treatment modalities for caries management, including a new resin infiltration system.

Seemingly against all odds, dental caries still affects most people in the US. While fluoridated products, school-based screening and cleaning programs, better patient education, and professional and chemotherapeutic interventions have all impacted certain populations, caries is still the most prevalent chronic childhood disease and continues to affect a high percentage of adolescents, young and middle-aged adults, and seniors. Much research has proven that dental caries is not just an occasional cycle of cavitation but a complex and infectious disease process. Historically, addressing the caries challenge has relied on prevention and restoration, with no intermediary means to stop lesion progression. Recently, a technique called caries infiltration was introduced that fills the noncavitated pores of an incipient lesion with a low-viscosity resin by capillary action, creating a barrier that blocks further bacterial diffusion and lesion development. This microinvasive method for stabilizing early lesions requires no drilling or anesthesia and does not alter the tooth's anatomic shape. In cases of white spot lesions in the esthetic zone, it also eliminates opaqueness and blends with surrounding natural teeth. This article presents an overview of caries prevention initiatives and a case demonstrating the new caries infiltration technique. Combined with shifting the focus to caries risk assessment, this promising technology may prove to be a significant addition to the profession's caries treatment armamentarium.
