The principal reason of gingival inflammation is bacterial plaque, along with other predisposing factors. These predisposing factors are calculus, malocclusion, faulty restorations, complications associated with orthodontic therapy, self- inflicted injuries, use of tobacco & radiation therapy. The contributing factors to gingival inflammation & periodontal destruction are deficient dental resto...

Theodore maiman in 1960 invented the ruby laser, since then lasers technology has holded the attention in dental practice and has revolutionised dental treatment. Lasers have been used in initial periodontal therapy, surgery, and also in implant treatment. Lasers have various periodontal applications including calculus removal; for removal of the pocket epithelium; soft tissue excision, incisio...

BACKGROUND Dental implants require regular maintenance. It is crucial that the instrument used for maintenance be able to remove plaque and calculus from the implant surface effectively and efficiently, while causing minimal damage to its circumference. Some ultrasonic scalers may be useful for implant maintenance; however, no clinical study has examined this. This study evaluated the treatment...

Children suffering from decreased renal function may demand unique considerations regarding special oral and dental conditions they are encountered to. It is mentioned that renal function deterioration may affect the hard or soft tissues of the mouth. Having knowledge about the high prevalence of dental defects, calculus, gingival hyperplasia, modified salivary composition and tissue responses ...

This study is a follow-up of one made in 1998-99 on first-year dental students in Monastir. Now in their fifth year, we assessed the effect of dental studies on students' oral health practices and dental health. Of the 155 students in the first study, 140 were still enrolled. Periodontal troubles, malocclusion and dental decay affected 84.3%, 80.0% and 43.0% of the students respectively. Compar...

OBJECTIVES Dental infections, such as periodontitis, associate with atherosclerosis and its complications. We studied a cohort followed-up since 1985 for incidence of angina pectoris with the hypothesis that calculus accumulation, proxy for poor oral hygiene, links to this symptom. METHODS In our Swedish prospective cohort study of 1676 randomly selected subjects followed-up for 26 years. In ...

This paper describes levels and progression of supra- and subgingival calculus undisturbed by active professional intervention or home care between 1970 and 1985 in Sri Lanka, or when removed at regular intervals between 1969 and 1988 in Norway. In the Sri Lankan tea laborers, both supra- and subgingival calculus formation started before age 14 years. At 40 years of age, all participants and al...

AIM To describe the oral health status of a group of Brazilian patients with chronic renal failure. MATERIAL AND METHODS Retrospective review of the medical records of patients with chronic renal failure, of whom 13 (4.5%) were in a predialysis stage, 158 (55%) were on hemodial...

BACKGROUND Dental diseases are among the most frequently reported health problems in drug abusers. However, few studies have been conducted on oral health of methamphetamine (meth) abusers in China. The aim of the present study was to investigate the caries and periodontal health profile of former meth abusers in Eastern China. METHODS A cross-sectional study was conducted on 162 former meth ...

Introduction Deposits of dental calculus when present either above the gingival margin or within periodontal pockets retain pathogenic microorganisms and their products, and have been linked to gingivitis and periodontitis.1,2 To ensure that clinicians are able to reliably detect calculus deposits, a range of special devices have been developed to augment traditional examination methods which r...
