For standard single implant placement, prophylactic systemic antibiotics either before or after, or before and after the surgical procedure do not improve patient-reported outcomes or prevalence of postsurgical complications.
In this study, the provision of PM led to minimal tooth loss, especially due to periodontitis, for a mean period of 10 years after APT. The completion of APT without PM may predispose patients to lose more teeth compared with patients who undergo PM.
The median VAS scores for all PROM parameters were generally low and reduced to near zero over a week following all three surgical procedures tested. Time after surgery and shorter surgery duration were associated with lower VAS scores in all the PROM parameters in this cohort of patients. Surgery type was not associated significantly with VAS after adjustment with other important confounders. Low prevalences of post-surgical complications were reported.
Aim: The aim of the present study was to determine the facial gingival profiles of teeth with a healthy periodontium in an Asian population.
Methods:A total of 51 patients with a healthy periodontium were examined. Gingival thickness (GT) and gingival width (GW) were assessed at the maxillary and mandibular incisors to the first molars. GT was measured by transgingival probing (GT-TGP), and probe visibility through the marginal gingiva (GT-TRAN) was assessed. Results between groups (anterior and posterior, tooth types) were analyzed using one-way analysis of variance and t-test.
Results:The mean age was 30.3±11.4 years, with 27 females and 24 males. The mean GT-TGP was 1.39±52 mm, while the mean GW was 4.59±1.34 mm. Considerable intra-individual and interindividual variation in GT (TGP and TRAN) was noted. GT increased from the anterior to posterior, and was thinnest at the mandibular centrals to the first premolars and maxillary canines. GT-TGP and GW were influenced by tooth type, plaque, recession, and TRAN, but not age, sex, or ethnicity. GW were recorded lowest at the mandibular canines and all premolars. Thin gingiva was recorded at 63.8%-92% (GT-TGP<1.5 mm) and 75%-90% (GT-TRAN) of the anterior teeth.
Conclusion:A high percentage of anterior teeth had thin marginal gingiva. There was poor agreement between GT-TGP and GT-TRAN.

The purpose of this review article is to provide the dental practitioner with an understanding of the interrelationship between periodontics and orthodontics in adults. Specific areas reviewed are how periodontal tissue reacts to orthodontic forces, influence of tooth movement on the periodontium, effect of circumferential supracrestal fiberotomy in preventing orthodontic relapse, effect of orthodontic bands on the periodontium, specific microbiology associated with orthodontic bands, mucogingival considerations and time relationship between orthodontic and periodontal therapy. In addition, the relationship between orthodontics and implant restorations (e.g., using dental implants as orthodontic anchorage) will be discussed.
This study evaluated the use OF bioactive glass (BG) for repairing/regenerating periodontal intrabony defects. Fourteen systemically healthy patients participated. Each patient had 2 contralateral sites with > or = 6 mm clinical probing depth and radiographic evidence of an intrabony defect. One defect was treated with flap debridement plus BG (test) and the other with flap debridement alone (control). Baseline measurements included gingival index (GI), plaque index (PI), position of the free gingival margin (S/FGM), clinical attachment level (CAL), probing depth (PD), and mobility. At the time of surgery and at surgical reentry (9 to 13 months later), hard tissue measurements included: stent to defect base, bone crest to defect base, and defect width at the bone crest. One-way repeated ANOVA was used to analyze the treatment effect. Friedman's test was used to detect any significant changes of GI, PI and mobility at different time periods (baseline, 3 months, 6 months, and reentry). For multivariate analysis, the random coefficients mixed effect model was applied to adjust the intra-correlation effect. Both treatments resulted in decreased PD and gain of CAL. These changes were only significant (P < 0.05) for the BG treated sites (PD reduction = 1.24+/-0.43 mm, CAL gain = 0.87+/-0.38 mm) from baseline. Defect fill was significant for test (1.1+/-0.4 mm) and control (1.4+/-0.4 mm) alike (P < or = 0.01). Although BG treated sites had more PD reduction and CAL gain than debridement only controls, there were no statistically significant differences between groups for any parameter measured. Further studies are required to clarify the beneficial effects, if any, of BG alloplast in treating periodontal intrabony defects.
ObjectivesTo investigate the effect of defined versus undefined periodontal maintenance after implant therapy on the prevalence of peri‐implant complications.Material and MethodsTwo hundred patients who underwent dental implant therapy in the National Dental Centre Singapore (NDCS) from 2005 to 2012 were recruited. One hundred patients had regular periodontal maintenance (defined maintenance programme group, DMP), and the other 100 patients had no documentation of periodontal maintenance (undefined maintenance programme group, UMP). Full‐mouth bleeding scores (FMBS), periodontal probing depths (PPD) and peri‐implant probing depths (PiPD) were evaluated within 6 months of prostheses delivery (T0) and at re‐examination (T1). Peri‐implant bone level changes were analysed radiographically.ResultsThe mean follow‐up time was 6.8 years. Five out of 289 implants were lost (cumulative survival rate = 98.3%). 6.0% of DMP patients and 20.0% of UMP patients had peri‐implantitis (p = .003). Peri‐implantitis was defined as bleeding on probing, increase in PiPD and peri‐implant bone loss ≥ 0.5 mm. At the implant level, 4.0% of the DMP group implants and 17.2% of the UMP group implants were diagnosed with peri‐implantitis (p = .0003). One implant in the DMP group and 13 implants in the UMP group had bone loss ≥ 2 mm (p < .0001). Multivariate regression showed that absence of regular maintenance (OR = 0.24, p = .003) was significantly associated with peri‐implantitis.ConclusionsRegular periodontal maintenance was associated with a lower prevalence of peri‐implantitis and peri‐implant bone loss. Patients with treated periodontitis without regular maintenance after implant placement were at higher risk for developing peri‐implantitis.
